Motor mounts were broken what's resulted in the vehicle lunging me forward when coming to a stop. The check engine light for the hybrid battery also came on. The result is the car shaking and shutting off more than once when attempting to accelerate from a stopped position. Once was in a very busy intersection. It shut off when coming out of a bank parking lot and turning on to a busy street.

On numerous occasions (35 plus times in past 2 months) I have experienced a terrifying complete loss of power to every electronically controlled component of my vehicle. For 3 to 5 seconds I have absolutely no power steering, traction control or headlights. My dashboard display goes blank, all radio and ac display goes off as well as their functions, my door locks repeatidly lock and unlock and my acceleration stalls out. After the power interruption all my dashboard warning lights (abs/ airbags/ stabilitrack/ traction control/ check engine) flash on and off for a few seconds when they all stop flashing the traction control and stabilitrack warning lights remain glowing. On 1 occasion while driving 75 miles an hour in the rain on a toll road with my daughter in the vehicle I experienced this situation only power did not return for 6 to 8 minutes leaving me to wrestle my rolling vehicle across 3 busy lanes of 75 mph traffic to the shoulder without power steering. I had to sit there with my child as traffic flew by until power returned and I was able to restart my car. I was absolutely terrified we were gonna be hit but we were on an elevated section of the roadway so the concrete barrier prevented us from getting out on the passenger side while contact fast moving traffic made exiting the driver side impossible as well. These issues have occurred in every type of driving scenario or condition. Randomly occurring while turning, accelerating, driving on an incline, braking, hitting bumps with no consistent factor being present. The date below indicates the onset of these repeat occurrences.

When I press down on the gas, my vehicle stalls about five seconds before it actually takes off. When I try to stop, it does not stop right away as I press down on the break. I've almost rear another vehicle on several occasions while sitting at a red light. I have to stay at least 15 feet away from the vehicle in front of me. My vehicle has shut down while I was driving. My engine light comes on and goes off periodically. If I turn my wheel to sharply (reverse or forward), it jerks, makes a loud noise, and then it feels like its about to cut off. I feel really unsafe driving, however, I have no choice because I have to work.

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.

Airbags do not deflate upon impact and electrical system short circuit on the printed circuit board and harness electrical short.

Sirius xm signal is not working and I have had the dealer do a reboot/reset on the radio. The reset worked for 2-3 months when I took it to gilchrist Chevrolet in tacoma wa. I have lost signal again and dealership is not very helpful with this type of situation. Sirius xm points their finger at gm and gm is pointing their finger at sirius xm. I just want my radio to work. Dealership does not seem knowledgeable about hybrid cars that gm manufactured.

Rear door locks (actuators) stopped working. First passenger rear lock failed to open or close. This happened after warranty coverage had ended. After some research I have found out that this is a widespread gm issue especially with 2008-09 gm SUV type of vehicles. My understanding is that the actuator motor fails. It is also my understanding that this electrical failure is due to a very inexpensive electrical actuator is used for the locking mechanism. This is a real safety issue and I am wondering when gm will be held accountable.

The electric door locks that engage when the vehicle is placed in gear have stopped working. If a parent relies on this system the doors may not lock resulting in a dangerous situation. This is a system failure. . .

I have never had any issues other than the recalls with my tahoe. I pulled into a parking space at my bank. As I got into the space. The brakes went to the floor and I put both feet on the brake pedal at this point. The rpms went up. It was like the engine came to life by itself. It self accelerated over the concrete spacer and sidwalk into the bank's brick wall. The airbag deployed upon impact. There was never a time it decelerated. There was no one in the car but me thankfully. There were no warning lights. There were no bells warning of the failure. I would estimate it took 2-3 seconds to go from almost stopped in a parking space to hitting the brick. I am so shaken by this incident and I have no idea what to do. GMC has been informed.

The contact owns a 2008 Chevrolet Tahoe Hybrid. The contact stated that the keyless entry malfunctioned. After locking the doors electronically, while driving 25 mph, the rear passenger door opened. The contact took the vehicle to an authorized dealer who replaced the door actuator on the rear passenger door. Now the front driver and passenger side door actuators were also malfunctioning; the vehicle was being repaired by the dealer. The failure mileage was approximately 50,000.

Complete vehicle failure - gm has admitted that they are at a loss as to how to fix the many errors (22) that show up on diagnostics. It was towed 3 times in 5 days & has now been at the dealership for 2 weeks & is still not functional.
