What this means for owners
- An investigation is not a recall. NHTSA has not made a defect finding here, and owners are not asked to do anything yet. If a safety defect is confirmed, the manufacturer recalls the vehicles and the repair is free.
- Check your vehicle for open recalls with a free VIN recall check.
- Had this problem? File a complaint with NHTSA. Owner complaints are the evidence ODI uses to open and expand investigations.
