Stop drivingWhat to do
- Notice when it happens (speed, braking, turning, cold or warm engine). It helps the mechanic.
- The most likely cause is oil leaking on hot engine parts: “Fix soon”.
- If anything feels unsafe, slow down, pull over somewhere safe and call for help.
- Check for open recalls with your VIN at nhtsa.gov/recalls. Recall repairs are free at the dealer.
