Is it true that manufacturers make cars bad intentionally so they break after warranty and you have to buy parts or a new car?
>>28843139that's called "planned obsolescence" newfag and yes it's new
>>28843139>2026 and newer cars are required to have an Internet connection that tracks your every movement>car will not start if it has no Internet connection>cellular standards get depreciated every 10 years or so>government has found a way to make all cars completely unusable after 10 years
>>28843141the truth is that they wanted this since the mid 1960s but didn't have the r&d to make it happen.they couldn't comprehend making stuff like spindles and axles and control arms that just fail at all, to them this concept of a car that just fails was a farther off concept than one that could fly.they always wanted you buying more of their cars, take a hard look at the course of history and how narrow of a time people trusted fuel injected computerized cars, that was the narrow window before the bean counters realized they could finally build cars that fall apart by design.
>>28843150>the truth is that they wanted this since the mid 1960sThey had it. The average American car back then wouldn't last more than 3-5 years before completely rusting out. Getting a new car every 3 years was the norm, compared to every 7 years today (and today's cars are still drivable when people trade them in)They started having to dip the cars chassis in response to Japanese cars coming and beating them on price and reliability.
>>28843162>The average American car back then wouldn't last more than 3-5 years before completely rusting out.Bullshit.I have multiple vehicles from the 60s and theyre more solid than anything made in the past 30 years.>you have to be 18 to post here
>>28843167Survivor bias. There are good reasons that vehicles rolled over at 100k.
>>28843162>Getting a new car every 3 years was the normmaybe 8-12 years and it was excessive but when you're a fucking upper middle class non mechanic and too fucking stupid to fix anything thats what you do.
Realistically vehicles are made better than ever.https://www.caranddriver.com/news/a60882953/average-age-us-cars-trucks-suvs-rises/
>>28843139Yes ,and you have to be blind not to notice it.In April 2009, a class action suit was filed against BMW in connection with HPFP failures. BMW settled the suit in June 2010. On 26 October 2010, following an ABC News story about HPFP failures, BMW announced a recall of vehicles with the pump in question from manufacturing years 2007–2010. The recall was applied to 130,000 cars, resulting in the replacement of the HPFP in approximately 40,000 of these cars. In the United States, the warranty period for the HPFP was increased to 10 years and 120,000 mi (190,000 km).On some cars, the HPFP was replaced multiple times without resolving the issue, potentially leading to the car being refunded under the Lemon Laws in some states.The High Pressure Fuel Pump issue caused BMW North America to extend the warranty for this pump to 10 years or 120,000 mi (190,000 km).The warranty period for the fuel injectors was also increased, to 10 years or 120,000 mi (190,000 km).An updated design for the fuel injectors was also introduced.Due to problems with rattling wastegates caused by premature bushing wear,BMW extended the warranty period for wastegate-related issues to 8 years or 82,000 mi (132,000 km).These warranty extensions only apply to the United States.
>>28843176The average age being just 5 years before 2006 is astounding. Suggesting most people bought an assload of cars.
>>28843179Why wouldn't you when they were always improving and were cheap as dirt?It used to be that the moment a car passed 50-80k miles you'd start looking for a new one in order to maximize the trade-in value.Now cars are way too expensive and stealerships offer bottom dollar trade-ins (just to turn around and sell your old car for near its original MSRP) and cars haven't really improved on any front, so people stick with them for as long as they can. It's not that old cars couldn't go 250k+ miles, people just didn't care to keep them that long because the market supported quick car turnover.
Some cars in the 70s and 80s came with manuals BY THE MANUFACTURER on how to do shit like change the head gasket. today they warn you not to open the bonnet and pay several hundred for the manufacturer to fix it themselves.
>>28843246>today they warn you not to open the bonnet0_0How is this even legal?
>>28843139No and anyone who says yes is an absolute retard. It's never ever in a company's best interest to intentionally make a bad product. If it was then Nissan would be the most successful auto maker in the world. If you make a car and it breaks, people don't go "oh that car was a huge piece of shit, what a waste of money, I'm going to buy another one". They buy a different car. They more often than not buy a Toyota who has established a reputation for making cars that don't break down often
Yes.The counterpoint is that once you set that goal line, then you need to deal with the fact manufacture defects will push vehicles into warranty limits. You also have to deal with selling the same car, but in a area with longer nation warranted warranty. The economics is that you don't want them to break after warranty, but a bit down the line after that, so the defects from manufacture also pass the warranty line. But that also means the good engines from that production batch quickly passes 3x or 4x warranty.
>>28843246thats very british
>>28843272Then why are so many post 2010 cars built so shit poor and maintenance hostile?
>>28843272Although Mercedes-Benz does not explicitly state that "we earn more from parts than from cars," an analysis of its business model and financial reports clearly indicate that its after-sales business (spare parts, accessories, service) generates significantly higher margins than new car sales.While car manufacturers typically achieve single-digit profit margins on new car sales (often below 10%), spare parts are characterized by significantly higher margins, sometimes reaching several hundred percent (!)It's worth noting that in 2022, Mercedes earned an average of €7,135 per unit sold, making it one of the leaders in this field. However, it is the parts market that ensures a steady cash flow after a car is sold.
>>28843278I pick and choose my english dialects. Whichever sounds right to me is what i use. Be your own man.
Planned obsolescence and walled gardens.All thanks to lightbulbs, casino watches, and iPhones.. thanks white people for being greedy...
>>28843198When I went to the dealer they wanted to give me 5% off. Then they wanted to deduct that entire discount from the value of my trade and put me back at MSRP.
>>28843283i mean that its very british for your cars to have manuals how to fix it, american cars would never
>>28843246>today they warn you not to open the bonnet and pay several hundred for the manufacturer to fix it themselves.
>>28843141>>28843150GM has been doing planned obsolescence since the 1920s you historylets. This is nothing new, the only thing that is new is the ability to leverage new advents in computing to precisely calculate the very month a part will fail, so that it is right after warranty and not with huge variance as in the past.
Cars "fail" at around 150k miles because owners can't fathom that machines wear out and need routine maintenance.Your trans fluid is complete trash by 150k and any attempt at remedying that problem is far too late.Vehicles that haven't seen a spark plug change and run rough as fuck.People ignoring oil changes running around with 10% fuel contamination, blowing out their piston rings, excessive bore wear, bearing scuffing.By 150k the suspension is trashed and should be getting shock and strut replacement with all mounting parts for them including bolts.Calipers need a rebuild by the 3rd or so pad change. Brake fluid NEVER gets changed.It isn't the manufacturer's fault that machines wear out. It isn't the manufacturer's fault that people are too stupid to understand routine maintenance.They profit from the culture of it though so why waste effort, people are going to ignore reality anyways.>what save money for fixes I can't do that I have to get a new loan that's 25% or more of my income until I die
>>28843162If the japs lasted longer why are 60s and 70s jap cars so rare compared to American.
>>28843139g*rman ones do
>>28843336Because he intentionally omitted that while mechanically these jap cars were more sound, they had rust proofing that competed with the British in how fast it would crumple up the car.
>>28843328Really? I thought US brands from that era would be all for it. In fact i swear Ford was one of them.
>>28843335Other wear items that are relatively cheap and easy and go a long way in keeping the big stuff from breaking:>pcv/egr units>the electric signal solenoids for the trans line control and torque converter lock/unlock>coolant changes>keeping the fuel tank above 20% (gauge indicated)>changing battery before it's weak, cleaning batt terminals, greasing the terminals,>to prevent wire corrosion>air filter every 30k miles>cleaning the radiator>accessory belt, tensioner and idler
>>28843150Its even worse now, they want you financing their cars till they break and you roll over the negative equity into a new car. Its automotive usury
>>28843364they're made to be fixed easily but the car companies wouldn't tell yuo, they would assume you know how to already or you bought a haynes manual for it
>>28843282This, my dealer breaks even on service and sales but absolutely kills with parts and it's not even close
>>28843334That's not planned obsolescence, that's perceived obsolescence, perfectly harmless unless youre a consoomer. Now computer modeling and metallurgy is so refined these manufacturers can quite literally build a car to break right out of warranty
>>28843335Ah yes, it's my fault the plastic water pump cracked and failed
>>28843368Sounds like a lot of work...
>>28843334facelifting the car every 3.5 years =/= planned obsolescence.
>>28843387Yes, it is your fault for buying a vehicle with a plastic water pump.
>>28843404Based, normies get fucked
>>28843329What piece of shit is this?
In the pate 90s it was well established that cars were built with a seven year lifespan. The was designed to die after seven years.
>>28843430This is why you don't see any cars from the 90s or 2000s on the roads anymore, but tons from the 80s and earlier.
>>28843433the 90s was a mistake
>>28843139Warranties are determined more by the product than the reverse. Manufacturers will determine how long X% of parts last, then say the warranty is slightly shorter. Don't like it, but yourself a whole new car instead of small parts
>>28843426Mercedes EQS
>>28843444Ah, an EV.People who buy EVs aren't typically the handy types, especially not people buying Mercedes-Benz EVs.
>>28843457Mercedes-Benz honestly died with Daimler.
>>28843281Because the people making the cars work for rich people who don't know anything about cars. >we need this much money to make the car better>no i will give you a lesser amount of money and just make it good enough brb i have to go buy a third golf courseThey suck because the parts are supplied by the lowest bidder. Because they laid off 25% of the rnd team. Because half of the factory workers are barely trained illegal immigrants. Because the focus testing groups said they wanted a bunch of features from more expensive cars so now you have to figure out a way to copy it without increasing the price, which means shoving even more low budget faulty tech in without proper testing
>>28843171>Survivor biasretarded reddit take because almost no domestic rwd car had issues going to 200k miles.>muh rustdoesn't count because they're literally putting corrosive salt on the roads, if you cared you wouldn't live in a yankee state.
>>28843397>>28843385Planned obsolescence includes obsolescence from styling changes as it is still 'planned'. I understand that's not what OP is strictly talking about but it is very much within that definition. It is still a way to get you to dump your car.
>>28843550Your cope is delicious
>>28843593NTA but you're the delusional one, no wonder you didn't respond to that anon with substance. Those buzzwords are your crutch, just remember it's easy to kick them out from under you.
>>28843598No reason to engage in actual conversation with him. Hundreds of thousand of them were built and hundreds of thousand died before the mythical 6 digit odometer rollover. I hate the myth that they were just built better
>>28843198Cuase they broke at 100kAsk anyone from that time was common for vehicles to be toast before then.
>>28843397Yeah dude forgets GM used the same power trains for years then only did marginal updates.
>>28843139A lot of GM shit feels like that.
>>28843272I talked to a retired GM engineer.He was part of the group that designed the V6s in the mid 90s.He said the engines were downgraded multiple times because corporate thought lasting over 150,000 miles was unrealistic for sales.I'm not joking.Planned obsolescence has been around since the late 70s at a minimum.Toyota assumes the lifespan of a car they make will be 200,000 miles.GM, Ford, Dodge exe assume 100,000mi or less.
>>28843139No, despite what some people think it wouldn't make sense. A lot of car brands heavily rely on brand loyalty to sell their vehicles IE "my grandpa drove a Ford, my dad drove a Ford, they were all reliable, so I'm gonna drive a Ford". In fact up until the late 90s a lot of cars rolled the odometer over at 100k because they didn't expect people to really drive the car past 100k miles.
>>28843904GM is the worst of the US car brands, this doesn't surprise me. Luckily enough the current L87 engine disaster might be enough to significantly hurt GM to where they actually have to make good cars/trucks again. So far the L87 recalls have cost GM over a $1b because its such a shit engine. Possibly the worst gas V8 made since the old Northstar, from any car brand.
>>28843608Anon,>>288439351 billion is a drop in the hat anon.These car giants are billions in debt.LT 6.2LJust the machining surfaces were shit.Otherwise it's not a bad engine.
>>28843904>Dodge exe assume 100,000mi or lessnot true, Dodge engineers their engines' rotating assemblies to go as long as possible so they can control in some respects where they fail (cheap, easily replaced plastic bits)their willingness to accept poor quality parts from suppliers and really unbelievably bad human quality control in the past has been their downfall. you literally can't trust mopars made in some years or some some factories or platforms or whatever not because of a pure failure in engineering like ford or gm but because of shitty careless factory workers or cheap suppliers.
>>28844051>Never replaced a Dodge transmission from the last 30 years.Anon......
>>28843139I design semi trucks and I've never heard of this. Bad design is an outcome of shitty project management 10/10 times. Here's how I've seen my employer change over the last 15 years.Old boomers started retiring. These guys weren't all experts, but a lot of them had a personal interest in cars and maintained some kind of classic muscle car. We do a hot rod show every year at work and these guys always had really beautiful stuff going. Some guys ran shops on the side too. These are mainly replaced by Mexicans, Indians, and women. Lots of excel and powerpoint jobs are created while the design teams get whittled down and outsourced. The big obvious problem aside from being so far from the plant environment and the customer is that these people generally don't work on cars or have them as hobbies, so the sort of practical, mechanical know-how goes out the door. There's been a big reorientation around having "good processes" because nobody can think or do work for themselves anymore. If you're working with India, the 13.5 hour time change means you have to give them a lot of explicit instructions and guides to follow because you'll be sleeping while they're working. And you can forget any working knowledge of SAE or ISO specs for things, that simply doesn't exist for them.Obviously this bad quality means bad parts. As warranty rates go up, so too does the frequency of recalls, FRACASes, and other internal course correction work. Because more and more time has to be spent on correcting women- and Indian-designed parts, the major project-level work starts to suffer. I knew one manager who would create clean-up jobs intended to be handled after a big program to ensure the time needed to correct all the bad work was had. Durability and reliability testing rarely catches all the variants in the programs either. You get to SOP and your oddball or edge case stuff might not have made it on a truck at all.
>>28843139>hahah yeah we're making it bad on purpose that's right...if only you knew
>>28843141Planned obsolecence is only new it you're a new fag. It's been that way since electronic replaced electrical in cars.
>>28843904>He was part of the group that designed the V6s in the mid 90s.>He said the engines were downgraded multiple times because corporate thought lasting over 150,000 miles was unrealistic for sales.yeah like others already pointed out, with the average millage being about 14-16,000 a year, and the average age of a car on the road in 90's being about 7-8 years old, he was right. building a car to last twice as long as the owner expects to drive it is just a waste.
>>28843150why then is the average age of cars on the road higher than it's ever been?
>>28843457>>28843444also the only thing under the hood are high voltage cables that WILL kill you if you don't know what you're doing
evil ford ceo: "hehe these stupid paypigs wont know what hit them when we pay for all these recalls"
>>28846487oh they only do recalls if their lawyers determine its cheaper then the lawsuits. ironically, if you ever hear about a recall, its because they are desperate for you to do it because itll save them money. otherwise why would they give a fuck, the costs of lawsuits is already rolled into the general running costs, those lawyers are already on retainer.
>>28846553you know what would be even cheaper? making a car that works.
>>28846562oh, no, god no, are you joking or something? how do you sell the same person a car every 5 years if the first car lasts forever, are you nuts or something?
>>28843368>>pcv/egr unitsWhat is this?
>>28843141Its not new, its a thing since Henry Fords days.
>>28843303>thanks white people for being greedyThe main people behind these changes don't identify as white for some reason.
>>28843334That's not the same as mechanical planned obsolescence. This was to sell more units since the car looked different it must be better than the previous year. The mechanical planned obsolescence really started taking off in the 80's-90's. Plastic parts started taking place of metal parts with GM knowing this new plastic part would fail faster.
>>28843139Conspiracy theory.
That's the American mentality yes and why you should NEVER buy American. The Asian mentality is make it as reliable as possible to boost the brand/corporate image worldwide as a manufacturer of quality.
>>28846643this. people dont know it but the reason japanese cars did so well was because they knew it was gonna be exported and they just straight up assumed americans would never remember to replace oil and coolant and designed around it
>>28843145>that tracks your every movementin the USA this has been happening for 2 decades; most people just didn't know
>>28846735Just because phones have SIMs doesn't mean we should accept cars having them.
>>28843139>Is it true that repair guys fcuk up perfectly good cars to make you go away.Yes. My yearly inspection guys just decided to fail a car (with more faults than it went in with) because Mercedes parts cost more than regular parts.They're on a race to the bottom.
>>28846735Yep, young people have got cheaper insurance for about ten years now if they give the cars telemetrics to them directly.
>>28843139Its true for all mechanical engineering. Design steps are:1. What does the client need it to do2. What does the client need to pay to have it do the thing.3. How long does the client need it to do the thing4. How do we avoid responsibility of any problems that do come up.When choosing a bearing for example, you pick it based on how many hours you expect it to run and what kind of duty cycle you expect. You dont just go in the cataloge and pick the highest price bearing you can because itll last the longest. Now multiply that by every part in a car. Its honestly a miracle they still work after the warranty period at all. Maybe not chevys, but the rest of cars.
>>28846736m8, phones barely have sims anymore. i guess some of those poor people phones do, but there hasnt been a sim slot on apple phones since 14
>>28846768>appleWell there's your problem.
>>28846774what about it, boomer? you one of those guys who should be window shopping for coffins who complain about having to "take your eyes off the road" to change the music or something while driving, while the rest of us have been using the voice control for like, a decade now?
>>28846781VW voice control must be nearly thirty years old now. It's just as shite now as it ever was.Have fun with your staring at the camera that is making sure you are watching it.Have fun being micromanaged in your car.
>>28846783>It's just as shite now as it ever was.jesus christ boomer>Have fun with your staring at the camera that is making sure you are watching it.jesus christ boomer. dont forget your rotary phone and to vulcanize your bike tires or something

>>28846811Your mom still answers.
>>28843139Yes. Google "planned obsolescence".
Now Anon, this is important, so please pay attention.We have been trying to reach you about your car's extended warranty.If you don't send us your money immediately, you could be at huge financial risk from having to pay for all of your own car repairs.
>>28846822That as a pop up on your cars screen must be a pisser.
>>28846818i accept your concession
>>28843139Yes. Did some work on the inside of the industry and the given runtime of any component is 10,000hrs for a product with a 5 year guarantee. There's a lot of time spent calculating mechanical wear for this purpose and you typically achieve the target by using cheaper, faster wearing materials and components. The crazy part is if you go to far over the target hours the component is sent back to the drawing board.
>>28846826Yup, and it's only the beginning.Soon, all sorts of advertising content will be delivered to your direct line of sight whenever you start up your car!For safety's sake, your vehicle will be immobilized and you will be unable to drive until you view and acknowledge the advertisement.
>>28846854My car is the last generation that will tell you that you are being naughty without preventing you from being naughty.Future cars will by purpose make you want to take public transport.
>>28843139Yes. And it only gets worse as time goes on.Enjoy your plastic engines.
>>288468773D printed, no less.
>>28846881Metal 3d print heads and blocks ought to be easy.Forged items like rods and cranks less so.
>>28843139They don't do that to get you to buy another car, they're just cutting corners to be price competitive with all the other companies that are cutting corners
>>28844914Semis are a whole different beast because they're investments. In cars people care about the bells and whistles more than about how well it works at 150k miles. Why would a car manufacturer make their sedan thousands more expensive with things like metal thermostats, stronger chain guides, etc. If the consumer doesn't give a shit about it
Yeah. I saw Ferdinand Piech personally slash my tyres once my passat was out of warranty.
>>28843139Bought a 2018 Honda Ridgeline. Currently has an emissions light on and many functions of the truck are disabled until it is fixed. Look online to read many people have o2 censors failing early on these trucks. Only 74k. I have a 1999 Honda civic with 210k+ miles and the only thing I've done on that car was change oil and trans fluid from the first day I bought it.
>>28846943Oh no, a $100 part needs replacement after 8 years! Better finance a new one!
>>28846943>I have a 1999 Honda civic with 210k+ miles and the only thing I've done on that car was change oil and trans fluid from the first day I bought it.I assume the first day you bought it was last week?
>>28846768my iphone 14 has a sim slot
>>28846830you have to go back to preddit, zoom-zoom. get back on the bus.
>>28844914This is also why the Chinese are dominating, IMO. I’ll buy cheap chinkshit from Temu but it’ll still have well thought-out features, as if the designer was an actual user. It still breaks, of course, but it costs 1/100th of what something “Made in America (designed by jeets, made by niggers” does, functions better, and has the same lifespan/durability as jeetshit.
>>28843139GM certainly does. Some other companies are probably not quite as intentional about it and the incentives just bring them to the same place.
>>28846484I’ll be really curious to see how that math changes in coming years once all of the post-bailout cars become the oldest used options for most people. So many 90’s/early 00’s beaters that are still reliable out there keeping the used market alive. Once the oldest practical choice for people becomes something like a 2015 car, I don’t think that many of those are going to make it for decades the way cars used to. I bet that number goes way down (and also car ownership altogether along with it).
>>28846565Also, how am I supposed to monitor their every move and sell the customer’s data if they don’t have a new car loaded with telemetry?
>>28843430>>28843433Damn, Toyota and Honda must never received this memo. I see a lot of Toyotas and Hondas from the 90s: Civics, CRVs, Rav4s, 4Runners, Tacomas, Tundras, Land Cruisers quite a plenty around my city.I personally own a 98 4Runner with over 275k miles and it is being driven daily and taken off road every so often.
>>28846484i'd say it has to do with the advances in materials science and knowledge we have now. As an example, even the shitty chinese tyres you can get now probably have just as much grip as, if not more than, the premium performance tyres of a decade or two ago.CAD wasn't really a thing in the auto industry till the 70s at the earliest, and it gained momentum in the 80s. Back then if you had a part that you knew had to last X amount of time/cycles/whatever you'd overbuild it with some margin depending on how tight (or loose) management was, then build it to that. So you could get OEM parts that lasted a ridiculously long time. CAD software allowed the production of more complex shapes, but it was still yet to perform simulated stress testing of parts etc.Now with ridiculously powerful computers, manufacturers can simulate a part that will last pretty close to whatever duration is needed (such as the warranty period) and no more.
>>28847311jap bubble economy. everyone had bottomless R&D budgets. every customer is rich, luxury can only sell so much. we can afford to build parts that could survive a bomb dropped on them...but the customers still want more. what sort of funky gizmos can we add to get more sales?
>>28847311What city do you live in? I live and work as a courier in the greater metropolitan city of Melbourne and I rarely see any 90s cars on the road, and I'm on the roads for ten hours a day. I only see old classics on Sunday or extremely poor people driving old rust buckets. Even cars from the noughties are few and far between and the vast majority of the cars I see on Melbourne's roads are less than ten years old.
>>28847399I live in San Diego, CA, so one of few good thing about living in CA especially SoCal there is no concern with salt for snow/ice and general weather is not too much of a concern for steels to rust out on various cars.
>>28847419It hasn't snowed in Melbourne since 1986. Your argument is invalid.
>>28847520I didn't say anything about Melbourne being snowy or having harsh weather, all I said it was one of the few nice thing about living in SoCal and how vehicles here don't get fucked over due to weather conditions.If your car ownership of various car older year models are that bad then your population of car owners suck at maintaining their vehicles.
>>28847524Yeah, fair point. That's why I'm still using and maintaining my Windows95 machine because upgrading to newer technology is for wrenchlets.
>>28847273woah woah i said i already accepted it>>28847270oh. grim>>28846881no one mass produces 3d printed items, its too slow
>>28846484>>28847329Because MPG got so fucking good by 2015 that awd CUVs were getting 20 city/30 highway and midsize sedans like Altima were getting nearly 30 city and 40 highway. and the safety ratings were off the charts too. Its only trucks that went to shit in the 2010s, cars and midsize CUVs became fucking amazing
>>28843139They make em like that because that's that the normies want, have you ever tried to get a normie to pay for some control arms, some struts, whatever the fuck else is needed when the car has finally been paid off after 72 months, these people don't want to pay a dime to keep the car on the road, they would rather have a car that lasts less than a decade and they get a new one, and the car companies just said say no more, family.
