16: Chevrolet Tahoe 6.5L Diesel
In the 1990s, the Tahoe with the 6.5L diesel engine was a dream for many Chevrolet enthusiasts. The problem came with reliability, which was noticeably absent. The 6.5L diesel is well-documented for having many design flaws, from cracked heads to worse (via 6.5TurboGarage). Apart from its diesel reliability issues, this generation of the Tahoe had several flaws in general.
Interior quality in all GM trucks from the 1990s was lackluster at best. Door handles cracked and button fading is even more common. You’ll also run into problems like leather seats cracking along the sides. GM made millions by selling these trucks, but the interior quality and engine reliability would never lend you to believe that. For many Chevy fans, having a Tahoe with a diesel engine may have been a dream, but this generation is a nightmare.
