Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
MAS005265 MCL 26-17
To support an accurate battery health assessment and successful certificate generation, all prerequisites below must be completed before submitting the request. Dealers should verify the applicable software campaign status, explain the self-learning cycle to the customer, and confirm the required waiting period has elapsed.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
