Purchased from Carvana. Nine days after purchase came out to a dead battery took it to the authorized dealer and they said the battery was a bad cell battery. Replace the battery. Six days after they replaced the battery it was dead again. This time they had it in the shop for two weeks before they found the issue. It had been aftermarket wired with a GPS tracking system that was draining the battery. They said if I have any further issues with it, I need to take it to a dealer. They gave me a bag full of multiple components that had been added to the vehicle. I do not know how Carvana missed them all.

There was an instance a couple months ago where I was driving and my ignition stopped. To my luck, I was in a safe area to stop but it is dangerous for this to be happening with my car while I am driving.

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.

THE RECREATIONAL TOWING INSTRUCTIONS REQUIRE THAT FUSES BE REMOVED (STEP 5) BEFORE NEXT STEPS INCLUDING SHIFTING VEHICLE INTO PARK AND TURNING IGNITION TO THE ON POSITION .

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Chevrolet Sonic verdict →
