Help other owners — file with the regulator
If your vehicle is affected by this defect, filing a complaint with NHTSA, Transport Canada, DVSA, or your regional regulator helps build the data record. Each report contributes to pattern detection that can trigger formal investigations and recalls — protecting other owners of the same vehicle, not just you.
You can file at any time, even if your dealer or manufacturer is already handling repairs. The regulatory complaint is a separate channel that helps every owner of your vehicle.
Campaign codes across affected model years
The manufacturer internal campaign codes and NHTSA campaign numbers we have on file for every affected model year. Multiple codes on a single vehicle reflect successive campaigns — sometimes a new campaign supersedes an earlier repair that did not resolve the issue.
