2007 Chevrolet Uplander LS 4dr Minivan (3.9L 6cyl 4A)
So far (in one year), the sliders don't work right, the amber lights melted the front fascia, it misses at idle, the traction control light comes on all the time, the body electrical harness plug leaks and shorts, rear pull strap broke off, the windshield drain floods the interior of the car when it rains, the front wheel bearings went out, the steering messes up (traction control), the rear quarter panel windows don't open, the rear shocks went bad, leveling air pump doesn't work, stabilizer bushings went bad, and makes clunking at low speed.
Oh, and the rear hatch is rusting.
I have not had one of these problems with my 2003 Toyota, which has 3x the mileage.
GM's problem is their culture.
Make it really cheap, but try to make it look good.
Instead, they need to focus on quality.
Spend a little more money where it is needed to produce a product that will last.
I can't believe they tricked me into thinking that maybe they finally got their act together.
I know if i bought a new car off the lot right now, it would be the same old problems, because the issue is systemic to GM, not the specific model.
