“My 2009 hybrid tahoe accelerates uncontrollably on occasion. The issue arrises commonly in stop-and-go traffic when the hybrid system starts/stops the gasoline engine regularly. I notice in many circumstances when switching gas/electric modes the vehicle lurches forward. The feeling is the same as letting out the clutch quickly on a vehicle with a manual transmission. I have done as much research as I can and it appears the problem points to issues with the transmission fluid pump(s) and/or control modules. …”
NHTSA complaint #11104779, filed 2018-06, 100,000 miles“I have never had any issues other than the recalls with my tahoe. I pulled into a parking space at my bank. As I got into the space. The brakes went to the floor and I put both feet on the brake pedal at this point. The rpms went up. It was like the engine came to life by itself. It self accelerated over the concrete spacer and sidewalk into the bank's brick wall. The airbag deployed upon impact. There was never a time it decelerated. There was no one in the car but me thankfully. There were no warning lights. There were no bells warning of the failure. …”
