10 Cars That Damaged GM's Reputation

[Smokey]

Never owned any of below cars, but did own Ford Pinto. Really not a bad car, except when gear stick kept sticking.

From Popular Mechanics.....

GM has never had a stronger lineup of cars and trucks. But each of those cars is weighed down by the legacy of cars like the ten listed here.

1. 1971-1977 Chevrolet Vega


The art of building aluminum engine blocks was in its infancy back in 1971 and the unlined cylinder walls of Vega engines were scoring almost instantly. That led to lots of oil burned and early death for this engine. Throw in haphazard build quality and sheetmetal that you could practically hear rusting away, and the Vega truly rates as one of GM's great debacles.

2. 1980-1985 X-Cars


The problem wasn't so much the basic engineering of the X-Body cars as it was that no one apparently spent any time doing the detailed engineering that determines a car's success. So customers complained of disintegrating transmissions, suspension systems that seemed to wobble on their own mounts, and brakes that would make the whole car shudder every time they were applied.

3. 1976-1987 Chevrolet Chevette


The Chevrolet Chevette was already outdated when it appeared in 1976. Based on GM's "T" platform, it was a primitive, front-engine, rear-drive subcompact in a small-car world that was busy being revolutionized by front-drive cars such as the Honda Civic and Accord, Volkswagen Rabbit and Ford Fiesta. It was underpowered too, originally being offered with a 1.4-liter Four making 53 hp or a 1.6-liter version of the same engine rated at 70 hp.

4. 1982-1988 Cadillac Cimarron


There's nothing wrong with the idea of a smaller, more athletic Cadillac. But it was a terrible idea to rebadge the Chevrolet Cavalier and attempt to pawn it off as a true Cadillac.

5. 1991-1995 Saturns


Saturn's cars were thoroughly mediocre. Built around a steel space-frame with plastic body panels bolted on, there were gaps between the panels big enough to stick a hand through. Yes, the plastic panels were resistant to collision damage, but they discolored and faded quickly, and as they aged, they cracked. Beyond that, the first Saturns had four-cylinder engines that sounded like threshing machines but didn't make a lot of power. These cars were nothing special in either handling or looks, and they were neither particularly space- nor fuel-efficient.

2001-2005 Pontiac Aztek


While engineering the concept vehicle as a production machine, GM took an incredible wrong turn: the corporation decided to base the new Aztek on the existing platform of its front-drive minivans. And because the minivans had certain dimensions that would be expensive to change, the Aztek wound up with some of the most awkward dimensions imaginable.

1978*-1985 Oldsmobile Diesel V-8s


GM decided to base its new diesel V8 architecture on the existing gasoline Oldsmobile 5.7-liter V8's. Of course the modifications were extensive in order to handle the 22.5:1 compression ratio of diesel operation—much stouter iron block, new cylinder heads, reinforced bottom end—but it was still a series of modifications rather than a clean-sheet design. Soon after the 5.7-liter diesel V8 debuted in Oldsmobile full-size 88 and 98 models (during 1978), the engines started tearing themselves apart.

8. 1981-1984 Cadillac V-8-6-4


The technology was called "Modulated Displacement" back then, and the idea was that as engine load decreased, fewer cylinders in the engine would actually be fired to produce power. In other words, at full throttle, the "V-8-6-4" was a V8, as it reached speed it became a V6 and when cruising it was a V4. Unfortunately the solenoids and primitive electronics that were supposed to make this work rarely worked themselves. And even when the V-8-6-4 was running on all eight cylinders it was only making a laughable 140 hp.

9. 2003-Present Hummer H2


The problem with the H2 is that it's proudly politically incorrect in an era when the forces of political correctness are winning. The H2 gets crummy fuel mileage, its looks come straight out of the military at a time while the military is fighting an unpopular war, and it's freaking huge. When gas crested past $3 a gallon, the H2's sales cratered and they haven't recovered.

10. 1997-1999 EV1


With its aluminum structure, an incredibly aerodynamic body and a whole bunch of lead-acid batteries, the first-generation EV1 was able to go maybe 75 miles if driven with extreme care. The problem with the EV1 was that it was almost impossible to drive in traffic with anything approaching the ideal technique the car needed to stretch its range. So its real world range was often down around 40 miles and driving it was often a white-knuckle thrill ride as the driver tried to stretch out every last electron to make it to a charging station.
