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
- Check the battery age – most last three to five years.
- Make sure lights, chargers and accessories are off when the car is parked.
- Look for corroded or loose terminals.
- If it dies overnight, a parasitic drain test finds what is pulling power while the car is off.
