My complaint towards my 2008 chevy Tahoe Hybrid is while driving my trucks stalls, twice already while driving off a parking lot onto the street it has shut off on me. Is getting to a point that I am afraid to drive it, I took it to the chevy place they kept it for 8-10 through 8/17, pick it up and the very next day the truck began stalling, dropped it off on a Monday 8/21, called the service department on Friday 8/25 and they said they can't fix it but they are going to keep it over the weekend to see what they can do. I love my truck but afraid of it. . . I feel I am risking my life and the lives of the other drivers while I am on the rode.

Vehicle will jerk uncontrollably at times at parking lot speeds. Vehicle will stall at times when taking off from a stop. Vehicle will accelerate at times by itself witout pressing accelerator. Dealer claims it needs a new battery but cannot replicate problems. I disaggree with dealer and think vehicle is dangerous.

2008 hybrid tahoe slow reverse out of parking space, absolutely no pressure in the brakes. Put the pedal to the floor and vehicle came to rolling stop, 5-10 feet with pedal to the floor. Pressure returned after changing transmission to drive and pumping. Dealer could not duplicate. No warning lights or error codes when service checked it out. We completed buyback / lemon law with regard to this issue and transmission. Transmission was completely replaced at direction of gm engineers and had same issues present within 2-3 months.
