When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2015 Chevrolet Sonic

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2017051 30,330 units in Canada

Lights And Instruments

Certain vehicles may fail to comply with the requirements of Canada Motor Vehicle Safety Standard 108 - Lighting System and Retroreflective Devices. The headlamp high-beam lens is not marked with the bulb type, contrary to the requirements of the standard. Correction: An manufacturing change has been undertaken to prevent this non-compliance condition from continuing. No corrective recall action is required as the non-compliance condition is deemed to be non-safety related.

Recall 2016292 1,882 units in Canada

Electrical

Certain vehicles equipped with a "Bring Your Own Media" (BYOM) radio may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 114 - Theft Protection and Rollaway Protection and CMVSS 208 - Occupant Protection in Frontal Impacts. The radio software may fail to provide an audible warning/reminder chime that meets the requirements of the standard when the key is left in the ignition and the driver door is opened, or when the driver fails to fasten their seatbelt. This can sometimes occur when the driver turns the ignition off with the headlamp or hazard warning flashers on and then restarts the vehicle while the radio is going through the “sleep” sequence. The loss of an audible warning when a key is left in the ignition may increase the risk of vehicle theft, and may fail to alert the driver that he or she is unbelted, increasing the risk of injury to the driver in a crash. Correction: Dealers will reprogram the radio with corrected operating software. Note: This recall involves vehicles that were previously repaired under recall 2016-191 that now require re-inspection and repair.

Recall 2016191 29,849 units in Canada

Electrical

Certain vehicles equipped with a "Bring Your Own Media" (BYOM) radio may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 114 - Theft Protection and Rollaway Protection. The radio software may fail to provide an audible warning/reminder chime that meets the requirements of the standard if the ignition key is left in the off position and the driver delays opening the driver’s door for more than 10 minutes, or opens and closes the door several times. The loss of an audible warning when a key is left in the ignition may increase the risk of vehicle theft. Correction: Dealers will reprogram the radio with corrected operating software.

Recall 2015279 4,592 units in Canada

Electrical

Certain vehicles may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 114 - Theft Protection and Rollaway Protection, and CMVSS 208 - Occupant Crash Protection. The radio may become inoperative, causing a no-chime condition and disabling the audible warning if the key is in the ignition and the driver’s door is opened, or if a front outboard seat belt is not buckled. A loss of the seat belt audible warning may increase the likelihood of a front outboard occupant being unbelted, increasing the risk of injury in a crash. Similarly, the loss of an audible warning when a key is left in the ignition may increase the risk of vehicle theft. Correction: Dealers are to program the radio with updated software.

The driver, and front passenger interior door handles the metallic chrome coating starts to lose its adhesive. When opening the door from the inside it cuts your hands if you don't notice it. Both door handles started to have the same issue within the same year. My children, my wife and myself all have been cut from the same problem. I tried to remove the parts that caused the injury due to us not being home and still required to use the door handles. I didn't want further injury to occur to my family.

Bowling Green, KY

ELECTRICAL SYSTEM

First sign of problem - Sept. 2021. Driving on highway at about 35 mph. Simultaneously, engine quit running, door locks unlocked and all dash lights came. In a matter of less than a second the doors relocked, forward momentum of vehicle caused transmission to kick start the engine and jolt forward rather violently. Then the dash lights went off and the vehicle resumed normal operation. This continued to happen with increasing frequency. I took the vehicle to the local Chevy dealer to set up an appointment for service. When I explained the problem to the representative, he told me that the battery was the likely cause. I went to an auto parts store and had the battery checked. It did, indeed, have a bad cell. I replaced the battery and the car operated fine for several months but the problem began to recur, infrequently at first but continued to worsen. I discovered later that the same problem also happened when when the car was sitting idling. The difference was that without the forward momentum of the car, the engine did not restart and required being shifted into neutral and started with the key. Also, when driving at a speed of less than about 30 mph, the forward motion was not enough to kick start the engine and shifting into neutral and using the key to restart was necessary while coasting in traffic. Final symptom, the above has happened only now the dash lights go out and the vehicle does not respond at all. After several minutes and several attempts the lights come back on and the vehicle runs. The car had 55,563 miles on it when I bought it and in just over 3 years, I have put 6,237 miles on it and it now sits because I am afraid to drive it. I have had the vehicle back at the dealer twice since having the new battery installed. They simply tell me that they cannot recreate to get a code and therefore cannot help.
