How to Act on This Recall
- Owners: Contact your authorized dealer to schedule the remedy at no cost. Remedy is covered under 49 U.S.C. 30120.
- Fleets: See the Fleet Recall Workflow Guide for the operator workflow to sweep your VIN list against this and other open campaigns.

How to verify your vehicle is affected
- Find your VIN. Locate your 17-character Vehicle Identification Number on the lower-left corner of your windshield, on the driver's-door jamb sticker, or on your vehicle registration. The VIN is the only reliable way to confirm whether a specific vehicle falls under a recall — make/model/year alone is not enough.
- Check your VIN on this site. Enter the VIN at /vin/ to see every open recall tied to your specific vehicle, including 21V953000. Our lookup pulls directly from the NHTSA recall database and refreshes daily.
- Cross-reference with the official NHTSA recall search. For a second source of truth, run the same VIN through https://www.nhtsa.gov/recalls. If both this site and NHTSA show the same campaign as open for your VIN, it applies — schedule the repair.
- Contact your dealer if affected. Bring the campaign number, your VIN, and your registration to an authorized dealer for the make. The dealer performs the remedy at no cost. If you've already paid for a related repair, bring the receipt — the manufacturer is required to reimburse pre-recall repairs that addressed the same defect.
