I know it's relative, but if you were a low mileage driver (like me) and drove like an old lady (like me) and were a stickler for maintenance (like me) ... shouldn't the majority of today's vehicles last many miles?
I've read the smaller JEEP SUV's were borderline junk, however, we had a Compass as a company vehicle that approached 100k trouble free miles. I'd be leery of a Fiat, but they're a tiny part of the U.S. market now.
Can't really think of any brand new junkers on the market.
I´ve got 2 Jeep Wranglers. One is a 2008 with about 186k or so miles. I´ve thoroughly beaten the scat out of it on trails ranging from mud to rocks to sand for 16 or so years and it´s reliability has been outstanding. The worst thing that ever happened was the computer getting fried, althoiugh I now suspect that it was a glitch caused by the electronic swaybar disconnect that would have been an easy fix. It runs like brand new. Maintenance is simple. It does use oil some of the time, but you just keep on top of it. It had the transmission replaced at 116k due to a noise and occasionally popping out of gear, but I would have lived with that if not for the lifetime warranty.
My 2018 JL Wrangler has been nearly flawless, and I´ve beaten harder on it than the 08. It is 5.5 years old and is just a blast to drive. No major issues. There have been 3 recalls now on the clutch, but mine has experienced no issues at all. It also had delamination on the nav screen but Jeep replaced that under warranty.
So if those are among the worst US vehicles, then the best must be perfect.
My 07 Corvette was trouble free, according to the previous owner and Carfax. 58k miles when I bought it. I had to replace a bad harmonic balancer, which is a very well known LS2 issue, but otherwise, it´s history is sterling. I´ve put nearly 2k miles on it in the 6 or so weeks I´ve owned it. I´ve seen these with 250k on them running great, so I have very high expectations for this car.
All of my vehicles get meticulous maintenance, including regular washes with high quality care products. But they get driven hard in the elements for which they were designed. They were not babied. I have zero complaints about their reliability. They´ve been as good as the Toyotas and Hondas I´ve owned.
The cars that belong in the garbage can, IMO, are BMW´s. Between my son, daughter, and her boyfriend, they´ve had about 6 of them. All have had expensive and frequent problems. My brother had a Z4 that was a hangar queen and it always had problems. He wound up paying 6 grand for a complete electrical re-wiring job.
I also had a 99 Mercedes E430 Sport. Loved the car, but it had little issues galore, like seat switches that repeatedly quit working and climate control units that went wonky. It also wore tires out waay prematurely and there was only one shop in town other than a dealer that even had the proper equipment to align it, let alone a tech that knew how to use it. I still liked that car, though. Great engine and transmission! Silky smooth and fast! And it had timeless styling. It still looks good on the road, even today, almost a quarter century since it was designed.
