Dear GM Executive Office, I am writing in frustration and disappointment after being told today by Chevrolet Customer Assistance that the case I opened (Case # [XXX]) was simply a "dealer complaint" and that no further help would be offered - despite my vehicle exhibiting a recurring, safety-related malfunction covered under Special Coverage N232395330 - Turbocharger Replacement. To Whom It May...

My car has had CAM shaft issues upon buying the car. I have taken the car to Chevrolet in Dallas and in Forney, TX and the car still has the same issue. My car engine check light has remained on and consulting a personal mechanic, they informed me that this could be a recall issue and that I should report it.
The contact owns a 2018 Chevrolet Sonic. The contact stated that while a 95-pound passenger was seated in the front passenger’s seat, the air bag system was deactivated. The vehicle was taken to the local dealer who was unable to determine a failure and indicated no failure was found. The manufacturer was notified of the issue. The failure mileage was 15,000.
The has as well as mileage is not accurate and it constantly changes even while not driving which is adding more miles to car than actually is and you will never know how much gas you have in car truly which is safety concern especially if you are driving on interstate and can’t tell how much gas you have in car and suddenly run out of gas while other are behind you going 70 mph which can cause a ...

MY RADIO TURNS OFF AND ON, ON ITS OWN. ALSO WHEN I HAVE MY BLUETOOTH TURNED ON FOR MY PHONE, IT GETS STUCK AFTER I HANG UP THE PHONE AFTER A CALL. I WAS DRIVING HOME FROM WORK ON A STATE ROAD. MY RIGHT WHEEL BEARING WENT OUT AND I HAD TO REPLACE IT LAST YEAR.
THE PASSENGER SEAT BELT DOES NOT CLIP OR WILL COME UNDONE AT ANY GIVEN TIME. I MADE THE DEALERSHIP AWARE OF THE CONCERN WHEN THE VEHICLE HAD APPROXIMATELY 39,000 MILES. THEY STATED THAT SINCE IT WAS OUT OF WARRANTY IT DID NOT QUALIFY FOR PRODUCTION DEFECT. THIS IS A SAFETY CONCERN THAT COULD ENDANGER THE LIFE OF A PERSON IF WEST BELT FAILS DURING A CRASH.

MY 2018 CHEVROLET SONIC RADIO SCREEN WENT BLACK WITHOUT WARNING WHILE I WAS DRIVING. I LOST ALL FUNCTIONS THROUGH THE RADIO SCREEN. THIS HAPPENED A SECOND TIME IN ROUTE TO WORK WITHIN A FEW DAYS. I'M CONCERNED THAT THE RADIO MAY GO BLACK DURING AN EMERGENCY WHEN I NEED TO USE ON STAR.
THE 2018 SONIC IS NOT SAFE TO DRIVE IN THE SNOW. IT HAS NO TRACTION TO START FROM A STOPPED POSITION, NO TRACTION TO STOP AND NO ABILITY TO CONTROL STEERING OR TURNING.
DURING NIGHT OPERATION, THE BACKLIGHT OF THE CENTER SCREEN IS SO BRIGHT IT CAUSES DIFFICULTY SEEING THE ROAD. THE INSTRUMENT CLUSTER IS AT AN ACCEPTABLE LEVEL (AS ADJUSTED BY THE SWITCH TO THE LEFT OF THE STEERING WHEEL), BUT THE CENTER SCREEN IS STILL TOO BRIGHT. A SIMPLE FLOATING SOFTWARE BUTTON ALLOWING A DISPLAY OFF FUNCTION WOULD ADDRESS ISSUE. AS IT IS, THE DISPLAY OFF FUNCTION IS HIDDEN ...
