Tl-the contact owns a 2008 GMC Yukon. The contact stated that while driving at approximately 25 mph, while approaching a stop sign the brake pedal was depressed but the vehicle did not stop. The gas pedal was depressed but the vehicle did not accelerate. Another vehicle crashed into the front passenger of the contact's vehicle. The air bags did not deploy. The contact suffered a concussion and the pregnant front passenger sustained back injuries and received medical attention. A police report was filed. The vehicle was towed to an independent mechanic where it was not diagnosed or repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000. Sg.
This is twice that I've received the p2138 throttle body sensor code, which causes reduced engine power and has subsequent issues around stabilitrack/awd. The first time was in the middle of an intersection, we limped out of the intersection at 3 mph. Today, my wife limped home from the store. This is extremely frustrating and should have been recalled a long time ago!!.
The vehicle does not accelerate when the accelerator is pressed. The vehicle take 5-10 seconds before responding, resulting in delay of merging and stalling at stop lights. It becomes dangerous when entering a highway and taking off, I have had individuals almost slam into me and I have ran into a construction zone. It suddenly take off, leaving the driver off guard.
Reduced engine power intermittently and without warning vehicle will not go above 35 mph. Has occurred five times with a different "fix" each time. One of the times it occurred my teenage son was driving on the interstate and had to pull over. Another time it happened my daughter was driving the vehicle and fishtailed taking a corner and had continued deceleration going up the bridge. Major safety issue!.
