Complaint history

When NHTSA received these reports. Changes in reporting alone do not establish a change in failure rates.

Problems owners report

Listed groups have at least 3 complaints. The page includes the 20 largest groups plus any additional flagged groups; some complaints are not assigned to a group.

AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.
