Chevrolet Sonic stalling problems

Filed Jun 22, 2026 · Engine · TX

Engine Cooling System (Thermostat Housing / Water Outlet) The vehicle suffered a premature structural failure of the factory engine coolant thermostat housing. The component, which is manufactured from a fragile plastic composite, cracked completely open without warning, causing an immediate, rapid loss of engine coolant. This constitutes a severe safety hazard. A sudden, catastrophic loss of engine coolant under normal driving conditions puts the vehicle at immediate risk of severe engine overheating and sudden engine stalling or seizure while in motion. If the engine stalls unexpectedly in high-speed traffic, it strips the driver of power steering and braking assistance, drastically increasing the risk of a serious collision. General Motors is fully aware of this pervasive material defect across the Chevy Sonic model years, yet they refuse to issue a safety recall, forcing owners to operate vehicles with inherently flawed, dangerous plastic cooling components. They also refuse to help in getting the vehicle repaired or share the cost.

UNKNOWN -- During driving the vehicle the radio and power steering will stop working, locks and key for occasionally have issues, and the car shuts down and has to be re-started. Sometimes will take a minute or two to be able to be re-started. If car stalls at high speeds could cause a catastrophic accident, injuring possibly killing driver or other drivers due to not being able to control the car. Car has recently been serviced replacing the radiator, coolant tank, and purge valve (this was throwing the check engine light). No codes can be found and the problem cannot be duplicated. Happens at random times, nothing triggers it.

Car was taken to a mechanic. The diagnosis is that the 16186 Catalytic Converter Internal Damage. This forces the car to keep stalling. Upon further research, certain models had this recall. I called GM and they said my car is not one of the ones that had the recall how ever it has the same failure that the other recalls do.

01.24.2023 Purchased Chevy Sonic 2012 three weeks ago (12.27.22) w odometer at 33,688 and manuf. date of 03/2012. It has multiple recalls, inc transmission, that GM has reported resolved. I have had to schedule a transmission rebuild for $3,200.00 in February. After pressing on gas pedal, the vehicle hesitates as though it is going to stall, then lurches forward. On open road it will buck. When slowing down to stop or make turns, it bucks and lurches. The problems duplicate those stated in almost all of the complaints reported on this site. If GM has reported this vehicle as properly repaired, then I am stuck. Also, the questionable low mileage of a ten year old vehicle and dates of the recalls make me wonder about where and when or if all the recalls were truly resolved. There is one accident reported on this vehicle, Sept. 2022; was the accident caused by the same powertrain related problems?

Once again, my doors unlocked then relocked, my dashboard lights went out and the engine stalled. I was on the KU campus when this happened 3 times within 6 blocks. This is getting very scary, especially when i am in a busy area of town. No codes have ever popped up. This has been happening since May 2022. I will keep reporting, hopefully there will be a recall soon. Very frustrated with this situation!

On September 2, 2022, the locks on my car unlocked and relived while I was driving at about 20 mph. This keeps happening over the last 4-5 months. This time it happened twice in two blocks near my home. I have reported this several times. No codes ever come up. Sometimes the car will stall but always starts right back up. I know I am not the only one with this issue. Please find a cause and issue a recall to get this fixed! This can be very dangerous even life threading if there is an accident because of it.
