Selected complaints filed with NHTSA by 2007 GMC Yukon owners, lightly cleaned up (personal details are redacted by NHTSA).
Travelling on an FM road, going 55 when Yukon began accelerating on its own, even when I took foot off the accelerator. tapped brakes, thinking cruise control had engaged. Vehicle swerved violently. Speed kept increasing. Saw I was traveling 75mph! Braked hard! Felt as if acceleration was fighting against the brakes. Then spun out in the middle of the highway, spinning around 1 1/2 times while fully braking. Finally I slowed enough to throw it into park, regardless of what it might do to my transmission, I had to stop the vehicle. I came to rest straddling the lane I had been in and the oncoming lane, facing the direction from which I came. Traffic behind me had seen my struggles in time to stop back far enough that they weren't endangered and there was no oncoming traffic at that moment. The fuel propulsion system (throttle?) seems to be at fault. …
2007 GMC Yukon denali. As I was driving...engine light came on, following with vehicle stability control, traction control disable then reduced engine power and it wont let me drive more then 20 MPH. Took it the dealer, replaced terminal wires, replaced BCM module ($1100). Two days later same lights comes back on dashboard...took it to the dealer and they told me I need throttle body replaced ($631). Then even more issues came, as you stopping for the stop light, but the truck jerking forward while foot on break and as stopping it makes a thud noise when slowing down. Contact GM said they'll be able to help me out but then they decline for any help and simply told me there is nothing they can do. Now dealer is telling me I need breaks, ball joints, up control arms, shocks. Truck has under less then 100K miles and most of these should last more then 100K. …
This is another incident that occurred the same week as my last complaint. While driving home from lunch I slowed the vehicle as I was going down a hill, this did not require any use of the accelerator pedal. Upon slowing down my vehicle displayed the following messages: "service traction control", "service stabilitrack", "reduced engine power". The SUV would not accelerate over 15mph requiring my to pull to the side of the road. The vehicle shook violently until I was able to put it in park and turn off the engine. After 10 minutes of sitting on the side of the road I stared the engine again. The SUV started right up but the "check engine" light remained on until the following day. Engine codes lead to a faulty throttle body position sensor which was replaced after the incident on 7/13. I took my vehicle to the GMC dealer today who informed me of the same problem yet again. …
Tl* the contact owns a 2007 GMC Yukon. The contact stated that the vehicle shuddered intermittently with the traction control and check engine warning lights illuminated. The contact stated that the vehicle hesitated while attempting to move off from a traffic light. The contact contacted jack winegardner Chevrolet (11001 md-210, fort washington, md 20744, [phone]) and was informed that the fuel injector and fuel rail needed to be cleaned. The vehicle was repaired. The contact added fuel injector cleaner however, the failure persisted. The vehicle was taken back to the same dealer and the contact was informed that the fuel pump was defective. The check engine warning light remained illuminated. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 244,000.
While driving to work on the interstate I approached slow moving traffic. Upon slowing down my vehicle displayed the following messages: "service traction control", "service stabilitrack", "reduced engine power". The SUV would not accelerate over 15mph requiring my to pull to the side of the road. The vehicle shook violently until I was able to put it in park and turn off the engine. After 10 minutes of sitting on the side of the road I stared the engine again. The SUV started right up but the "check engine" light remained on. This was a terrifying experience on a busy stretch of hwy 88 outside of chicago. I hope others do not have to go through this experience.
On 10/08/2020 I was driving in heavy traffic at 5 pm when the engine lost power and the dash started flashing first it was turning off the stability control system and the next message was going into reduced engine power mode. At that point, the vehicle dropped to about 30 MPH with full throttle and I had to maneuver thru traffic to get off the freeway. Not easy to do with a car that will only do 30 MPH or so. With caution lights blinking and waving at cars I nearly got rear-ended twice before I could get off the freeway.
My name is [redacted] , I reside in tucson az, I own ad my wife and I drive a 2007 g m c Yukon slt, my concern is our Yukon seems to lunge at times, what I mean is, when we stop our s u v at stoplights, stop signs, or pulling into our garage the RPM raises to what I feel is an unsafe level .which requires us to apply the brakes in a manner for which I and my wife feel is excessive pressure being applied to the brakes. We have expressed our concerns to our local g m c dealership more than five times in a one year time frame. Their response is we and our techs, can not duplicate the issue we have expressed! We both feel this is an unacceptable response. I know that the system involved is non mechanical system that operates the gas peddle it operates the accelerator peddle by the use sensors and or sending units.please advise. …
Tl contact owns a 2007 GMC Yukon. While driving at highway speeds or lower, the transmission shifts very hard. There is also a harsh pounding sound coming from the transmission. All of the electrical components on the instrument panel failed. The dealer changed the crankshaft sensor. While driving, the contact cannot tell when the gear is in neutral. The speedometer displays inaccurate speeds and the air bag light illuminates. The plastic on the window fell off and the front driver's side door handle sticks when it is pulled, and will not go back in. The contact hears a rubbing sound coming from the steering column. The instrument panel cluster has been replaced and the check engine light would remain illuminated. The current mileage was 29,000 and failure mileage was 10,229. Update 09/10/08 the lug nut caps were missing, the check engine light was on. The gas cap was not sealing. …
I was traveling on the freeway at about 70 MPH coming from a supervision training class along with a co-worker and the following sensor lights started appearing on my dashboard: traction control off, stabilitrak off. This has continued to happen on a regular basis. I have taken it to the GM service at least twice and private repair facilities numerous times and the situation continues. It is now 01-28-2014 and the situation continues and is getting worse. Alone with the above issues now the "reduce engine power" light comes on and the engine shuts down. It has become very dangerous to drive this vehicle and no repair facility, GM or otherwise, knows how to fix the problem. I have to drive so this vehicle is what I drive but, it is dangerous and GM needs to fix it or recall for this issue. …
I took my daughter to volleyball practice and when I stopped at a red light the car was accelerating even though I had my foot on the brake pedal and it moved on a jumping mode to the front. I got so scared. The car moved forward we could have been involved on an accident on an intersection or hit the car in front of us. As that happened I noticed in dashboard the rmp counter was moving up as if it was were accelerating. It was pretty scary my kids and I don't feel safe to ride on the only car we own. I had a mechanic tell me I should take it to the dealer because it's a safety hazard. That it seem to him as a throttle system failure and it was very dangerous. When I turn vehicle on it happens too.
