Notes

SYSTEM: COOLANT SYSTEM.VEHICLE DESCRIPTION: PASSENGER CARS.

A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
