We are having problems right now with our 2013 Denali Terrain. GM knows it is a defect but is refusing to acknowledge and is calling it “normal”. The car has the anti collision audio and visual alert system. It does NOT have the collision breaking system. We will be driving in absolutely perfect conditions and out of nowhere the alerts go off and the brakes seem to make a grabbing sensation. Immediately, you have an “uh-oh” moment and instinctually brake the car, thinking you are about to become an insurance claim. We have been on the terrain forum website and others experience the same problem, which is quite unsettling. We have been told it is pre-charging the brakes in case you have to use them and if we don’t want it to happen we should turn the collision system off.
I bought a 1980 Buick Skylark brand new and it was the buggiest car I ever owned. I had a moderately steep driveway and I could put my car in neutral or reverse and push both feet against the brake pedals as hard as I could and the car eased backward down the hill. Absurd.
And that was just one of a page worth of design defects that car had. I swore I’d never own another GM car but couldn’t resist a 2003 silverado z71 for my farm in KY at a very low price and good condition. The instrument clusted went TU. It only cost $85 to get fixed (Myairbags.com) but it was another case of GM’s “Test in Prod” attitude about foisting known defects onto the public.
That kind of thing from any company is unacceptable when there’s ant kind of safety issue.
