2016 Chevrolet Sonic Complaints

ENGINE — Filed 10/15/2025

This car overheated and a head gasket blew. I am on a Facebook forum, and it seems like all of these cars have these problems. The Chevy Sonic ltz turbo 1.4 2016 is known for coolant issues and head gasket failures. My car only had 104,000 miles on it. It should last a lot longer than that, but this is a common issue. For some reason there was a recall but they stopped fixing cars with 1.4 engines that came out after 2014. There cars don't have temperature gauges and when they overheat they don't tell you until a light comes on the dash and by then it's too late and your engine is blown. This should be illegal. Chevrolet needs to fix this.

Radio malfunctions. Channels automatically change and touch screen doesn't work all the time. I believe 2015 Sonic has a recall for this issue , but not 2016. It appears to be the same issue.

ELECTRICAL SYSTEM,SEAT BELTS — Filed 08/04/2020

I BOUGHT A 2016 CHEVY SONIC LT IN JANUARY OF 2020. IT HAS ONLY HAS 30,000 MILES ON IT AND HAS BEEN WELL MAINTAINED. INITIALLY, I BELIEVED THAT THE COMPUTER WAS JUST SLOW. IN MARCH, 2020 I NOTICED THAT WHEN I WOULD TURN THE CAR ON THE RADIO/COMPUTER WOULD SOMETIMES TAKE SEVERAL MINUTES TO BOOT UP. THEN ONCE BOOTED, THE BACK-UP CAMERA LINES WOULD NOT SHOW UP. ONLY OCCASIONALLY WOULD THE GUIDING LINES APPEAR ON THE SCREEN. THEN, A PROBLEM DEVELOPED WHERE AFTER I TURNED THE CAR OFF AND LOCKED THE DOORS, THE RADIO WOULD CONTINUE PLAYING UNTIL THE VEHICLE WAS RESTARTED OR THE BATTERY WAS DISCONNECTED. THIS FIRST OCCURRED IN MAY 2020 AND WOULD OCCUR PERIODICALLY OVER THE NEXT SEVERAL MONTHS. IN JUNE 2020, THE RADIO WOULD RANDOMLY NOT BOOT WHEN STARTED OR BOOT EVEN MORE SLOWLY THAN USUAL. SOMETIMES I COULD DRIVE TEN OR TWENTY MINUTES BEFORE THE COMPUTER WOULD FINALLY TURN ON. OTHER TIMES THE COMPUTER WOULD NEVER TURN ON. YET AGAIN, THE ONLY SOLUTION WAS TO RESTART THE CAR OR DISCONNECT THE BATTERY. ON AUGUST 1, 2020, THE RADIO WILL NOT TURN ON AT ALL, EVEN AFTER RESTARTING THE CAR OR RECONNECTING THE BATTERY. NOW THAT THE RADIO IS COMPLETELY NONOPERATIONAL, OTHER SYSTEMS HAVE BEEN EFFECTED, TOO. FOR EXAMPLE, THE BLINKERS DO NOT SIGNAL PROPERLY. ALTHOUGH THEY BLINK, I DO NOT RECEIVE A NOTIFICATION THAT THEY ARE ENGAGED (NO BLINKING SOUND). THE SEAT BELT, DOOR AJAR, AND KEY IN IGNITION WARNING DO NOT SOUND ANYMORE EITHER. ADDITIONALLY, THE COLLISION NOTIFICATION AND LANE RECOGNITION NO LONGER PRODUCE AN AUDIBLE WARNING. IT DOES NOT MATTER WHETHER THE CAR IS STATIONARY OR IN MOTION, THE RADIO AND ALL RELATED SOUND COMPONENTS DO NOT WORK AT ALL. I HAVE NOT FOUND ANY SOLUTION YET. THERE HAVE BEEN RECALLS FOR PROBLEMS SUCH AS THESE FOR THIS VEHICLE, BUT NONE OF THEM ARE CURRENTLY OPEN.
