2012 Chevrolet Cruze Vehicle speed control Problems

“When the speed of the car starts to reach 50 miles a high pitch sound occurs. I cannot determined if it is related to when air conditioner is turned on. The noise will diminish when speed is lowered to about 45 miles. I cannot recall if this happens in the colder months but it does seem to happen in the summer.”

“I was driving down the interstate and my car started to lose power. The engine reduced power and service stabilitrak messages came up and the check engine light and traction control light came on. I got of the interstate and putted along, barely able to accelerate at stop lights, until I made it to my local chevy dealership. They don't seem to know what is going on and I'll probably end up doing a trial and error with sensors and throttles. …”

“My brakes keep going hard and not functioning properly. About a year ago I had my master cylander, brake booster, microswitch in the brake vacuum line, maf sensor and air intake hose replaced because the mechanic said those were the issues, I went 2 weeks without my vehicle, including breaking down for multiple days out of state.

Upon receiving a diagnostic reading, the code indicated a transmission control system or output shaft speed sensor. …”

“I was driving and the reduced engine power, service stabili track, check engine warnings came on. My car would only accelerate to 5mph. Luckily I wasn't on the freeway, was only going 20 MPH and almost home. Very dangerous. I put an end code reader on it and it's a p2135 code, throttle positioning sensor. I have been reading chevy Cruze forums as well as in chevy forums in the past week, a minimum of 1000 people that I can see have had this issue. Many have been in accidents because of this. Its occured in mainly chevy Cruze but also impalas, gmc vehicles. …”
