Filed Feb 4, 2022 · Brakes · 131,814 miles · MA

The contact owns a 2011 GMC Yukon. The contact stated that while driving at 60-65 MPH, the check engine warning light, the ABS warning light, the emergency parking brake warning light, the stability tract warning light, the warning indicator “Service Brake System” and other unknown warning lights illuminated. The brake pedal was depressed but felt rigid and failed to respond. The contact depressed the brake pedal with more pressure, but it hesitated to respond, causing 40 feet in stopping distance delay.

Having an ongoing issue while driving. I've ben on the highway in the rain and snow going 65-70 MPH as well as dry pavement. All of a sudden my dashboard will light up saying service traction control, brake system, ABS , park assist off and check engine lights up and blinks . I will loose my brakes I then have to pump my brakes several times to get to even slow down or stop . It's also happened when I am driving down a residential street. When I pull over turn the truck off and goes back to normal for a short distance. Weather doesn't seem to be a factor or speed. Taken vehicle to dealership and they don't find anything wrong. Had them replace bearings as well as speed sensors and it is still happening. And I had a code come up for cylinder misfire and knock sensor. Then take it garage and nothing is wrong.

Abs brake problem. Reoccurring engine problems such as misfire, low cylinder compression, afm lifters, camshaft, fuel mix and brake switch causes check engine light to come on. This causes stabilitrak and traction control to be turned off. Discussions with several mechanics indicated a new engine would be the only way to fix this problem. Even with a new engine, the problem persists. The check engine light continues to be "on" and stabilitrak and traction control continue to go on and off, and living in mi it is concerning me that I may lose these braking functions when I need them. Gmc has offered no solutions. Many, many forum discussions on the web indicate owners such as me should create a class-action lawsuit, as there does not appear to be a solution to this problem. The stabilitrak and traction control goes on and off as I am driving, typically on a highway.

Travelling at speed on the highway (60 MPH) , the engine light comes on and a stabilitrak message is shown. Power to the engine is dramatically reduced. Car shakes violently and it is difficult to get off the highway. A seconday message appears to check throttle body assembly. Very close to getting rear ended. This is a major defect that has to be addressed. It has also occurred on a 2014 gmc yukon xl that we own.

The truck was parked and running. It suddenly began to idle as if someone was pushing down on the gas. I immediately shut the car off. I turned it back on and the engine light was on and it read "reduced engine power". It seemed to drive ok. I called dealership and made apt for tuesday. (it was thursday) the next day I drove it to local garage to read engine code. It was p2135. The truck then stopped accelerating. It would not go over 25mph. It took about 2 full min to get it at that speed. When I would break, the truck would jump as if did not want to stop. The dealership diagnosed the problem as the throttle position sensor cover. I was informed that gmc is aware that there is a problem and has since corrected it. However, there is no recall as there is no alleged safety issues. I believe that when you have a 1,2, and 3 year old in the truck in rush hour, it is dark outside, and you are an hour away from home it is a huge safety issue when your truck won't accelerate! I have contacted gmc who refuses to take responsibility for this issue. Please issue a recall as this is a known problem.

The vehicle suddenly lost power and the stabili-trac system warning appeared in the dic, then the traction control system warning appeared in the dic, then engine power reduced by 16% in the dic. Drove vehicle to exit ramp and turned engine off. Vehicle restarted with only the check engine light on and no warnings in the dic. The engine did not however run smoothly. I took it to a dealer who clear some codes and replaced the tps. Checked all fuses. No further problem. However a friend has the same vehicle in a 2010 model. Same problem dealer replaced a throttle body. Check out the gm forum at [xxx] this forum shows literally hundreds of complaints about the same problem and in some cases causing accidents. My vehicle was repaired on 1-24-2013, and so far it appears that my problem has been resolved, however it appears gm is not really fixing the problem. I am concerned about this for the next out of town trip I take. *tr parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
