2011 Chevrolet Impala power train problems

“Grinding from turning. Numerous Radiators, Transmission problems over and over. Jerking not pulling. Stalling in the road.Control Arm needed again. Brakes and Rotors grinding.”

“Today, 6-12-2022, driving on US Highway 80 at 65 mph headed toward Phenix City, AL from Columbus, GA, the the engine shuddered, then the "Stabilitrack Service Light" came on, along with the check engine light, and a message for "reduced engine power." Then, the engine suddenly cut out as I was going uphill between the Riverchase Exit and the Summerville Exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under ZERO power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the Summerville Exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this Model, the Chevy Impala. I'm sure Chevrolet knows about this...the company should be forced to recall this car model and fix it before folks start getting killed due to…”

“The car was stopped at a stop sign, turned right onto the highway and the front wheels locked. The car would not move in any gear, even in neutral. A tow truck had to place front wheels on skids and drag onto the bed. The transmission repair shop never saw anything like it, all the gears on the trans axel were stripped smooth and metal fragments all over the inside of the transmission. Very dangerous situation if there would have been oncoming traffic.”

“AFTER ABOUT 30000 MILES THE TRANSMISSION SOLENOID(S) ARE GOING BAD INTERMITTENTLY. IT'S GOING TO BE A COSTLY REPAIR FOR A PART THAT COSTS AROUND 25 DOLLARS OR SO. THIS SEEMS TO HAVE BEEN A CONTINUING PROBLEM ON THE 4T65E TRANSMISSIONS. WHEN YOU ARE AT A COMPLETE STOP WITH THE VEHICLE IN DRIVE AND GO TO ACCELERATE YOU GET NO RESPONSE EXCEPT FOR HIGHER RPM'S AND THEN THE TRANSMISSION SUDDENLY ENGAGES AND YOU GET A VIOLENT SURGE FORWARD WITH A LOUD BANG. GM KNOWS ABOUT THE PROBLEM AND SHOULD INITIATE A RECALL TO INSTALL NEW AND IMPROVED SOLENOIDS.”

“THE BRAKES ARE AUTOMATICALLY STOPPING WHILE DRIVING ON A CITY STREET. THE TRANSMISSION HAS A PRESSURE VALVE CODE THAT WILL NOT GIVE A DEFINITE READING.THE AIRBAGS LIGHT STAYS ON ALONG WITH THE ABS AND STABILITY TRAK LIGHT STAYING ON.”

“VEHICLE RANDOMLY GIVES CHECK ENGINE LIGHT AND REDUCED ENGINE POWER, SERVICE STABILITRACK. AT THIS POINT ENGINE POWER REDUCED TO POINT THAT IS VERY DANGEROUS. WHILE PASSING (SAFELY) IT CAME ON AND I WAS STUCK IN ONCOMING LANE BECAUSE I DIDN?T HAVE THE POWER TO COMPLETE PASS. HAPPENS EVERY WEEK SEVERAL TIMES. THIS OCCURS WHILE DRIVING AND SITTING. EVEN IN PARK IT WILL OCCUR. COMPLETELY RANDOM WHETHER DRIVING, SITTING, OR IN PARK RUNNING. *TR”
