Owner reports
Selected complaints filed with NHTSA by 2007 GMC Yukon owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2007 GMC Yukon. The contact stated while driving 70 mph, the vehicle lost motive power and stalled. The contact pulled over, restarted the vehicle, and continued driving to her destination. The vehicle was not diagnosed nor repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 200,000.
We are making payments on this vehicle from tri-united in lubbock tx. All the engine lights are on and the air bags are missing this vehicle body appears to be wrecked the hood isn't sitting right. The dealership even asked if we could have the vehicle inspected in which it failed the first inspection.
I have had my vehicle for about 4 years now. I haven't had any issues with it up until July of last year (2014). I experienced my car jerking erratically and had to pull over. The car lost speed and could not accelerate. I had taken it to a mechanic who then said I needed a new transmission. I have had the transmission replaced. About 6 months later the jerking started again on and off, no loss of speed and it would only jerk going form first gear to second. I have not worried about it until now because the car would only jerk every so often. Now my traction control and stabilizer service warning message pops up. I have taken it to several places I have been told that I needed a throttle body, ABS module and both are not cheap to fix they all want to charge me $500- $1200 to fix the problem. I began researching and see that the issue I am having May be due to a manufacturing issue. …
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. …
While my wife was driving on the interstate highway at 55mph, the SUV check engine light came on, followed by a traction control warning on the display, then the vehicle went into "limp mode", reducing power and speed to approx 20 MPH. She turned on the hazards, and moved into the right lane as other vehicles went around her at the posted speed limit as the engine was bucking and missing. She exited the highway and limped the truck, barely getting up to 20 MPH to a service shop. They scanned the codes, the only one there directed them to change the throttle body, ($580). The vehicle ran good for 3 days, then all the same bells and whistles came back. GMC service said they have no knowledge of a problem. Upon researching this online, I found it's far from uncommon. If this has not caused an accident yet, its only a matter of time..
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.
As I was driving 'oil pressure is low, cut the engine off' warning came on and the oil light was on. That also triggered the traction control/stabilitrak light to come on. From then on whenever I drive the vehicle those lights come on as well as the check engine light. This is apparently a common problem with the GMC 2007 engine. There are multiple forms from Chevy, Cadillac, and GMC where consumers that have these engines are experiencing this problem. When we take it to dealerships we are told to change the engine. I was just quoted over $8000 to change this engine. I can't even sell this truck without losing my shirt. We need help out here. GM knows that this is a problem because the dealerships know. They are sweeping this under the rug until some people die because of it!
Tl* the contact owns a 2007 GMC Yukon. The contact stated that while driving, the vehicle started shaking while idling rough. The check engine warning light and several unknown warning lights illuminated. The contact heard a load revving sound coming from under the hood. The vehicle was driven to the residence. The contact scheduled an appointment with white plains Buick GMC (358 central ave, white plains, ny 10606, [phone]) to have the vehicle diagnosed. The contact received a callback and was informed that the engine needed to be replaced at a cost of $7,000. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 124,000.
2007 Yukon goes into reduced engine power on a regular basis. As a result, there was a crash on one particular incident. On a daily basis, it continues to and the engine cuts out as a result as well, no rhyme or reason. On the interstate, going 70 miles an hour the vehicle cut off, went into reduced engine power and myself and my family were just seconds short from losing our lives. This has all been reported to GM and we've gotten no resolution. Motherboards, gas pedals, gas caps, wires, everything you can think of has been replaced on my vehicle and it still goes into reduced engine power putting my families lives at risk. This is an extremely dangerous situation.
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.
