What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Accelerator went to the floor on its own. Owner applied the brakes , the pedal resisted and became hard, causing the vehicle to collide. The dealer has not been notified.
While driving 30MPH hit a tree and front was in a v shape after accident. Air bags did not deploy. Radiator and hood were no good. The bumper was split in half and the hood buckled in a 45 degree angle.
If you use the turn signal, the steering wheel will start smoking. Took vehicle to dealer and dealer didn't want to fix it. Turn signals still worked when applied.
Car would get horrid gas mileage, occasionally stall, exhaust smell under hood, black exhaust. The crossover pipe from each exhaust manifold has a common cracking on the bellows and must be replaced, they run $2500 from GM which just crack again, or $425 for jeff m one that doesn't crack. The pipe cracks cause fresh air to enter the exhaust and the oxygen sensor thinks the cars running rich, causing horrible gas mileage, oil contamination, and stalling.
