Recalls

No recall campaigns are on record for this model.

How long do they last?

How this was calculated

Every model year is scored over an identical window: complaints filed with NHTSA during the first 60 months after that model year went on sale. Without this, older cars look worse purely because they have had longer to accumulate reports.

Limitations. Complaints are unverified reports submitted voluntarily by owners; they are allegations, not findings, and reporting rates vary between models. Model years with fewer than 60 months on the road are marked provisional and excluded from verdicts. Cross-model comparison is withheld pending production-volume data.
