At 19,873 miles the stabilitrak and reduced power lights came on and the trucks speed would drop to about 30 mph creating a dangerous driving situation. The same scenario happened at 37,643 miles, 57,522 miles, and 78,224 miles.
I took the truck back to the dealership each time and was told the problem was the accelerator pedal/sensor and they replaced the parts. The second time I took the truck back for the same problem, someone from GM contacted me after I raised questions and concerns in an online discussion group. To Chevy's credit, the woman who contacted me was able to extend the warranty.
This has been harrowing for me in the past on the interstate as I tried to cross traffic and exit at 30 mph. Since she works in town, my wife has been driving the truck and the same thing happened to her in June, 2017. She was turning left across morning work traffic on an uphill grade when the power reduced and she was creeping broadside to traffic coming over the hill on a state highway. Her words were, “Scared the bejeebers out of me.”
I am again told the problem is a sensor/accelerator pedal issue that makes the stabilitrack light come on and the truck go into reduced power mode. The pattern has been consistent, treat the symptoms but don’t fix the problem, which is a safety hazard. When the service rep told me it was the sensor in the accelerator pedal I was not surprised, same old tired song. The dealership has a clear record of the same part failing, my concern is what are they doing to find the cause of the failure. Replacing the part offers does not instill any confidence.
Justin, the “service” manager, called. I told him the problem had not been fixed and he said according to his records it had. I replied the symptoms had been treated again but the problem had not been fixed. His comment was the “fix” lasted 16 or 17 months so it was fixed. He misses the point, there is an underlying cause for the same part to continue failing and creating unsafe conditions when driving.
