I got a code p2138 Throttle/Pedal Position Sensor/Switch. Upon doing my own research on this code I found out it is a manufacture defect. And they are aware this is caused because the manufacturer did not seal the antenna correctly so water gets in and damages wires and sensors

The vehicle is having electrical issues and it effects it by shutting off in the middle of traffic on a highway it also effects the throttle sensor by accelerating when you come to a stop at a stop light and the transmission jumps a gear when it does that.

While driving on a highway stabilitrack turns off then few seconds later traction control turns off then I get either a cylinder misfire or throttle body code. Truck then goes into reduced power mode with rough idle. I can clear the codes with obd reader and it runs fine for a while.

I own a 2010 Chevrolet Silverado 1500. While driving approximately 68 mph on the highway, the check engine warning indicator illuminated, service stabiltrack and reduced engine power warning all came on at once causing the truck to reduce speed quickly and dangerously on the highway. I was almost rear ended as the my speed went from 68 mph to less than 30 mph in an instant. Thankfully the gentleman was able to slow in time- through on his hazards and help escort me to the emergency shoulder. My truck has approximately 67,000 mile on it and this problem has now happened 5 times at various speeds. I have researched this matter and this is know issue and is all over the GM forums with multiple models. Each fix reported comes after customers have spent hundreds of dollars for the dealers to locate the issues. GM/Chevy are aware of this issue and yet there is nothing about a recall for this issue even though it is caused from a known defective part and causes a dangerous driving situation!

I was riding at about 25 mph engine reduce power light came on, engine had no power to pull. Engine stabilizer control light came on. This is about the third time this has happen. The first time it happen the vehicle had less than a 115,000 miles on it. The second time it happen I call the dealer they replaced a sensor on the throttle body. They told me if it didn't work that I would have to replace the throttle body out of my own pocket. Now it is doing it again. I think it something wrong with the throttle body system from the manufacturer. If this happens on a major highway it could cause injury or a fatality.
