general problems of the 2008 GMC Yukon

The passenger-side frontal airbag inflators, the determination was made that the propellant in these inflators may degrade after long-term exposure to high humidity and temperature cycling, which could cause the inflator to rupture during a deployment.

When beginning to drive forward after coming to a stop at an intersection. The vehicle will often stall in the middle of the intersection. Requiring me to switch it transmission into natural and restart it as it’s rolling. I almost gotten rear ended many times I always get honked at. It just a matter of time before it causes an accident. It sometime happens after turning as well. I looked at forums on this GMC Yukon hybrid. And it looks like many other owners are asking the same question and nobody is coming up with any answers. Other customers say the dealer told them the hesitation is normal. I took my truck into a local repair shop and he called me after three weeks saying it was done, but it still had the check engine light on and still is stalling out in intersections. Charge me $2000. This has been happening daily since I got the vehicle.

It started shutting off at a light for autostop. But when it would turn green it would intermittently just drop out of autostop without restarting. Then may start back up or maybe not, many time after restarting at the light it would died in the middle of the inspection. A parasitic draw kept killing the accessory 12 v battery replaced the 12 v battery but the problem continued. When the truck was running it would run flawlessly,before stalling. The code said to replace the auxiliary fluid pump. I had it a new auxiliary fluid pump installed. After this the vehicle wouldnt crank. They then worked through a service bulliten fixing a list of areas were the harness was chaffed and shorted. The truck has been out of commission the past 10 months and intermittently started twice during this time, it ran rough for 5 mins and died out at the first stop sign and wont crank again. Some times it will crank but not start.

Truck stop without any warning for no reason oil is leaking from the truck for no reason just got it not long ago.

The vehicle caught fire while parked and ignition turned off. Fire appeared to start in the engine area. Vehicle had been parked and turned off for approx 1. 5 to 2 hours before the fire was reported.

The car flashes reduced engine power, stabilitrack off and the car can barely go 30 mph. The engine runs very rough when it is doing this also. My code scanner displays code 641 which is open 5volt reference on bank 1. It does this more when the weather outside is warmer or the car has been sitting still while running. On more than one occasion it has happened while pulling out into traffic causing near misses and other times while driving down the highway. Just yesterday it did it 20 times in a four mile stretch. This car is no longer safe to drive.

Driving at 70 mph on highway. Vehicle gauges begin to act erratically, vehicle heaves and lurches, then 100% power failure. Nothing worked, even hazzard lights. Airbag light flashing on and off. Was able to put vehicle in neutral and move to the side of the road where the vehicle stopped. There was no power at all, had to manually open door locks. After 10-15 minutes, the power came back on and I was able to restart the vehicle and drive home. Happened again on 3/23/14. Again driving at highway speeds, the electric components (radio, gauges, power cord accessories) begin acting erratically and then 100% complete power failure while driving. The gm dealer cannot duplicate or find the problem. I feel 100% unsafe in the vehicle especially with my kids.
