ENGINE
The lifter valves for the dynamic fuel management system have failed twice resulting in an immediate loss of power, rough driving, and low speed. To replace the first time, it cost $3500 at a mechanic. The 2nd time that it happened (8 months later), we now have to have the engine replaced and it cost almost $10,000. GM has refused to take any ownership in these faulty lift valves and someone is going to lose control of their vehicle when this occurs.

Transmission has created shuttering at speed and jarring total stop decelerating from 2nd into 1st gear. Beyond the transmission this vehicle completely stopped and lost power at 55 mph due to faulty valve lifters and pitted cam lobe. These were two separate incidents. Transmission cause lose of power on incline. Valve lifters cause lose of power at high speeds. The dash board read outs no longer worked and I was on a Highway without the ability to maintain speed.

POWER TRAIN
The transmission causes the vehicle to shudder, lurch from a stop, at times it won't move forward (from a stoplight etc), it won't reverse other times. When driving down a freeway, the transmission allows the engine RPM to surge wildly as if I had put it in neutral and pressed the accelerator. This started at 85k miles approximately. It's into 90k now. The transmission had to be replaced at a cost of $6000

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Were driving and vehicle repeatedly suddenly braked in the middle of interstate or highway without any warning. We are so traumatized, and scared of this vehicle. It has happened before. Dealership says there is nothing they can do. This could have caused our life. GMC should be held accountable.

SUSPENSION
I was driving the vehicle heard a loud thumping sound got out to look and the driver side tire was nearly off the vehicle! Had I been driving on the highway I could've been killed/seriously injured by loss of control by way of steering. It looks like the upper control arm completely seperated from the tire at the ball joint causing the tire to fall away from the vehicle. There is a current recall out there for this make, year, and model. The vehicle has been inspected by the manufacturer. No warning lamps or messages have appeared.

POWER TRAIN
Transmission is slipping into neutral from a slow start and re-engaging with a hard bang to the point it feels like I’ve been rear ended from a vehicle behind me. It’s done it twice in two weeks and it seems to happen when I’m leaving from a stop or slowing down and then come back into the accelerator.
