Safety recall repairs are done free by the brand's dealers. A mobile mechanic cannot do recall work. Enter your 17-character VIN at nhtsa.gov/recalls to see open recalls on your exact car. "Park it" means NHTSA and the maker say not to drive the vehicle until it is fixed.
What to check first
- Note whether the light is solid or flashing, and whether the car drives differently.
- Check that the fuel cap is tight – a loose cap can set an evaporative-system code on many cars.
- Look at the other gauges: temperature, oil pressure and battery warnings change how urgent it is.
- Have the code read – a mobile mechanic reads it with an OBD-II scanner and checks the cause, not just the code.
