2012 Chevrolet Cruze vehicle speed control problems

“Check engine light, traction control light, tire pressure light came on. Message on dash reported reduced engine power, service stabilitrak, and car slowed to 16 no more than 20mph and would not go any higher.”

“The contact owns a 2012 Chevrolet Cruze. The contact stated that while his daughter was driving at unknown speeds, the vehicle lost motive power after 45 minutes. The RPM increased, and the vehicle failed to accelerate. The driver was able to pull over. There were no warning lights illuminated. The vehicle was towed to an independent mechanic, who was unable to duplicate the failure. The contact stated that after driving for 45 minutes, the vehicle lost power and went into LIMP Mode. The transmission had seized in fifth gear. The vehicle was taken to the local dealer, where it was diagnosed that the speed control sensor had failed. The contact was informed that the speed valve and transmission control module needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 90,000.”

“The car began to shake uncontrollably on the freeway at 55/MPH . The car then marked "Engine Power is Reduced", causing the car to no longer accelerate more than 5-7/MPH. This is a very dangerous situation because it can cause a terrible accident on the road since it's a random inconvenience. I have heard that many of these types of cars "Chevy Cruze" seem to experience the same type of problem. With that being said it's safe to say that as an owner this situation is far out of my control and it's definitely a collective problem with the type of car and make that it is. I ask for this to be immediately looked into.”

“DRIVING DOWN THE INTERSTATE DOING 70-80MPH AND THE CAR STARTS DINGING-STABILITRACK, TRACTION CONTROL, AND REDUCED POWER ALL COME ON AND THE CAR LOSES POWER WITHOUT ANY WARNING AND COULDN'T DRIVE FASTER THAN 5 MPH AND HAD TO GET TO THE SHOULDER OF THE ROAD WITHOUT GETTING HIT BY OTHER VEHICLES DOING THE SAME SPEED. THIS VEHICLE WITH THIS ISSUE THAT CAME OUT OF NOWHERE SHOULD NOT BE DRIVEN ON THE ROAD. I HAVE HAD SEVERAL ISSUES WITH THIS VEHICLE AND CEL LIGHTS ON BUT NOTHING THAT ALMOST COMPLETELY STOPS VEHICLE WITHOUT WARNING AND ALMOST KILLS EVERYONE IN THE CAR! I GET THEY ARE TRYING TO SAVE THE ENGINE OR WHATEVER FROM FURTHER DAMAGE BUT I AM PRETTY SURE THAT I WOULD LIKE TO LIVE AND NOT KILL ANYONE ELSE IN THE PROCESS OF THIS SO CALLED SAFETY PRECAUTION THE VEHICLE TAKES ON.”

“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. I TOOK IT TO THE DEALER AND I NEED A NEW THROTTLE BODY, THERE IS NO SPECIAL COVERAGE ALTHOUGH ITS OCCURED IN THOUSANDS OF VEHICLES IF NOT 10S OF THOUSANDS! IT'S DANGEROUS! THERE IS A SPECIAL COVERAGE FOR PEDAL ACCELERATOR FRACTURE BUT THEY SAY MINE IS FINE AND NOT RELATED TO THROTTLE BODY. THIS NEEDS TO BE ADDRESSED WITH CHEVY AND IT SHOULD BE RECALLED OR HAVE SPECIAL COVERAGE. HERE IS A READOUT FROM THE MECHANIC.”

“I WAS DRIVING IN SUBDIVISION AT 20MPH AND VEHICLE WENT INTO LIMP MODE. IT HAD A MESSAGE SAYING ENGINE POWER REDUCED, SERVICE STABILITY TRACK AND CHECK ENGINE LIGHT WAS ON. IT WOULD NOT ACCELERATE MORE THAN 5MPH. THIS IS VERY DANGEROUS! LUCKILY I WAS NOT GOING 70 ON THE FREEWAY. I'VE BEEN READING ON CHEVY FORUMS AND GM FORUMS OF THIS HAPPENING TO THOUSANDS OF PEOPLE. MANY GOT IN ACCIDENTS BECAUSE OF REDUCED ACCELERATION TO 3 OR 5 MPH. I TOOK IT TO THE DEALER IT HAS A P2135 CODE AND IS DIE TO A BAD THROTTLE BODY AND THROTTLE POSITIONING SENSOR. THE CHEVY MANUFACTURER IS NOT WILLING TO DO ANYTHING ABOUT IT ALTHOUGH IT'S A KNOWN ISSUE TO CHEVY AND GMC CARS FROM MANY YEARS OF VEHICLES, FROM WHAT I'VE READ 2009 TO CURRENT YEAR. MINE IS A 2012 CHEVY CRUZE LT. THERE IS A SPECIAL COVERAGE OF PEDAL ACCELERATOR FRACTURE BUT THE DEALER SAID IT'S NOT RELATED TO MY ISSUE, I HAVE A HARD TIME BELIEVING THIS. HERE IS A NOTE OF WHAT THE DEALER LOOKED AT AND DIAGNOSED.”
