Check it against this car’s mileage
Type the odometer reading on the actual car you’re looking at to see which of these problem areas owners tend to report before it, around it, or after it.
Too few owners named a mileage on this model to place issues against an odometer yet.

General Motors LLC (GM) is recalling certain 2018 Chevrolet Sonic vehicles. A joint in the driver's seat-back frame may not be properly welded, reducing the strength of the seat-back frame.
Risk: In the event of a rear-impact crash, the seat-back may fail, increasing the risk of injury.
Fix: GM will notify owners, and dealers will replace the driver's seat-back, free of charge. The recall began June 28, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 18178.

- Owners of this model report electrical system problems more than anything else. Has this car shown any electrical system symptoms, and are there repair records for it?
- Has this car been in any accident, and can you share a title history and any service records you have?
- How many owners has it had, do you have the maintenance records, and why are you selling it?
