Since I've owned the hybrid Yukon, I've had nothing but issues. GMC only made a limited amount of the hybrid models but due to the issues discontinued manufacturing them. Why weren't the vehicles taken off the market? started with the jolting from a stop, to not wanting to go into reverse, check engine light, to hybrid battery not shifting into gear, last power steering locked while driving then not starting at all. Had sat at the dealership for 4 weeks now sitting at another hybrid shop awaiting for the inverter converter control to be delivered and put in. Have spent thousands in the last 2 months repairing trying to figure out issues.
The contact owns a 2009 GMC Yukon denali xl. The contact stated while depressing the accelerator pedal, the vehicle experienced delayed acceleration. The contact stated that the check engine warning light was illuminated. The vehicle was taken to a local mechanic but was not diagnosed or repaired. The manufacturer was informed of the failure and informed the contact that they were unable to assist. The failure mileage was approximately 90,000.
Well the check engine light came on then the oil light came on I change the oil is still on the battery keeps dying I've already bought three new batteries nothing is working I'll still come out the car is dead check engine light keeps popping on and off the wheel the wheel thing keeps popping in and off I bought new tires it's still popping on and off I just don't know what's wrong.
Transmission dipstick tube broken. Not sure when it happened. It was noticed by my father about a week ago when he was looking things over. I just got the truck used from a dealer in sept.
I placed the vehicle in park on a level surface, I left the Yukon running and I got out and walked my great niece to a building about 30 feet from the vehicle. . I then turned to see the Yukon backing up on this flat surface, I ran to try and catch it but it hit a building and then came forward at me. I had to jump out of it's way and then chase it down. When I jumped in and hit the brake I then noticed it was in m1. I took it to a local GMC dealer who checked the transmission but reported finding nothing. I am now afraid of this car. How do you know when it will vibrate or jump from park to reverse again. This needs checking into. This Yukon went both backward & forward.
