“We were at a stop and we started to go and turn the truck hesitated and died in the middle of the road we restarted the truck back up and the check engine light came on and it hesitated when we started to go again and it was over excelerating and took a while to change from 1st gear to 2nd gear”
NHTSA complaint #11021339, filed 2017-09, 145,000 miles“My truck accelerates and abruptly stops while slowing down under 20 MPH. Under 20 MPH the engine is suppose to switch over to connect to hybrid battery system. Sometimes the vehicle abruptly stops while turning or sometimes the car cuts all the way off. I purchased the vehicle in 2010 and I have reported this problem since 2013. Overtime I took the vehicle back to the dealer and they would tell me that they couldn't duplicate the problem. I recently had major engine problems involving the lifters according to their diagnostic machine. The cost was 6000 to repair. …”
NHTSA complaint #11001416, filed 2017-06, 70,000 miles“Sometimes when I come to a stop my vehicle goes into the autostop mode, but when I go to accelerate it doesn't come out of autostop and jerks really hard then stalls out. Once I put the vehicle in park and restart it, it cranks right up but the check engine light comes on and stays on for about a day and then goes off on it's own. I have taken the vehicle to Gmc dealership twice and paid out about $700 for repairs that did not solve the problem. The dealership claims to not be able to find any codes even with the check engine light on. …”
NHTSA complaint #10762793, filed 2015-09, 84,000 miles“75% of the electric door locks on the above described Gmc yukon, including both rear door locks have failed in the locked position. This failure makes it difficult/impossible to open the doors - especially the rear doors. Because the car has only one exterior door lock; in order to open the interior manual rear door latches in an emergency, one must try to climb over/between the front seats (the head rests are no longer removable) - a stretch of 4'4 from the edge of the front seat to the latch which is located at the rear of the rear door. …”
NHTSA complaint #10576323, filed 2014-04, 32,106 miles“The contact owns a 2008 Gmc yukon denali hybrid. The contact stated that while driving 15 MPH, he applied the brakes but noticed that the vehicle had independently converted from the gasoline mode to electrical hybrid mode. The vehicle then stalled but regained power once the vehicle was at a complete stop. The vehicle was taken to the dealer for inspection but they could not diagnose the cause of failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 40,000.”
