For an industry that has been around for over 100 years, there is no excuse for so many unreliable cars and trucks. The engineers should be ashamed of themselves.

[raiden]

I think we are at the point where we need to simply identify reliable models and consider all others unreliable.

My 2000 Ford F150 4.2 V6 is still going strong. No car payment in 18 years. Never been in the shop. Nickel and dime problems only. Everything works, looks like new . Has 167, 000 miles and I will keep driving it as long as I can. My wife's 2021 Santa Fe Calligraphy is riddled with transmission problems. These newer vehicles today are mostly junk.

Profits over care and quality. The dark side of the ego, corporate thinking.

We bought a new 2018 Ford Mustang with the 10R80 transmission. To say I hate the thing would be a maximum understatement.

[tonelocrian]

No surprises here, but you forgot to mention JEEP's
massively horrible reliability records

[monterreymxisfun]

As the owner of a manual transmission Nissan, the CVT automatic results in an abundance of parts in the salvage yard which is very helpful.

[robertdryburgh]

It's a real shame when 15 to 20 year old vehicles with 150K+ miles are more relisble 11:39 than new ones.

[CraigWarden]

Bought a 2019 f-150, 3.6 eco boost with 90k km. Didn’t reach 91k. The cam phaser issue claimed that engine, no warranty, and
$8, 000 Canadian to fix it. I didn’t have the 8 grand to repair it, so drove it back to the dealer. Left it there. Never, if I live to be 1000 will I ever buy a Ford product again. Such a common everyday issue, and zero Ford solutions. I wish I had discovered your channel sooner. Keep up the great job

As a german I think you don't understand something. German modern Cars have a lifetime from 100-150.000km (approx 60-100.000 miles) or 10 years. The german law is extrem hard (thank you Green Party) with getting every year a technical test where the car must be in condition new. So german car producer plan a "lifetime" only 10 years or 100.000km. Everything else can handle the german technical test every year only with extrem problems and extrem cost. And the newest law is .... it's forbiden (privat or in a garage) to repair cars older as 10 years. And it was forbiden before to repair cars at home or to store 2nd hand car parts for older cars at home. You can't imaginne what is going on in germany. For example the technical test every year, you must have new wipers or you don't get the test. The car colour is part of the registration papers, you change the colour and you have a problem with your registration papers. and so on and on and on. This situation is political, not technical. In Germany we live in a time german carmakers leave germany because the german Green Party want to destroy car driving, car producing, want to remove roads, trys do destroy big companys, and so on and on, one and only to change germany to a green paradiese. From where job or taxes are coming Greens don't care, Greens don't think, Greens are idiots.

My coworker bought a RAV4 and needed a new transmission before 100, 000 miles. Our three kids all have Subarus and so do we, Crosstrek, Forester, Legacy and Outback and they have been gold. Absolutely no transmission problems on any of them. The one Legacy did have a gasket issue and needed a new engine, but it had almost 300, 000 miles which more than most cars get and no other major problems. I’m sticking with Subaru!

[scottcook]

Had a 2009 Nissan Altima, the CVT transmission died with 51, 000 kms on it, Nissan replaced entire transmission under warranty, price then was $4000.00 for new transmission. I own a 2008 Nissan Frontier with a regular geared transmission and never have had a problem with it. Will never buy another vehicle with a CVT transmission. Also currently own a 2016 Mazda, CX-5 with a regular geared 6 speed transmission never have had a problem with it. It now has over 213, 000 kms on it.

[attilato]

so basicly dont buy a new or second hand Car, just maintain your old one .

[auburn]

I have a friend who is a Mercedes mechanic. He told me to never think about buying one. I’ll stick with my Lexus.

[allanzylbert]

I agree with Mercedes-Benz. I had 2 over the years, and both were great until they hit around 50k miles, just after the warranty ended and as you said, the big problems started. These Car Mfg should be ashamed, but as we see, they dont care

[martygillespie]

In defense of the manufacturers, some of these issues are being created by the need to meet government mandates. Notably CVT’s, small displacement turbocharged engines, cyllinder deactivation. Even Honda’s 1.5L turbo is leaking water into the oil and blowing head gaskets, and Toyota’s new twin turbo 6 on the Tundra is a disaster. And those two companies are historically the most reliable on the planet. When government mandates force extreme engineering, the consumer pays the price.

[spunkush]

Whats crazy is Subaru suggest fluid changes on their CVTs and diffs every 30k miles, but they dont suggest CVT fluid changes in the USA. They do this to reduce the "cost or ownership" number on the window sticker, but it dooms the CVT to fail.

[bradbowles]

We are going to keep our 2017 Toyota Sienna until we can’t drive it anymore. No turbo, no CVT and a proper V6 engine. Get the government out of the car manufacturers’ business.

[petestaint]

Shari, another awesome video. Thanks for the heads up on these piles of crap. 👍

[jswong]

The biggest reason why European cars' reliability today is absolute crap compared to 20-30 years ago is mainly due to nonsensical emission standards that borders on impossible to comply with internal combustion tech. You end up with engines being highly strung with high boost pressures, extremely lean air-fuel mixtures, high compression ratios, etc. These are all elements that should not coexist in an engine yet they're hallmarks of European engine tech today.
