NHTSA Complaint #11718285 — 2023 TESLA MODEL 3

A bolt securing the rear subframe assembly is loose and missing its nut. This condition has caused damage to the rear subframe assembly, which now requires replacement. The vehicle was inspected by a licensed dealer who confirmed on video that no impact damage, scraping, bending, or collision damage is present on any surrounding components. The only affected area is the bolt and nut connection point. The dealer's professional assessment is that this is consistent with a factory assembly defect — either the nut was never installed or was not properly torqued during manufacturing. No routine service or alignment would require access to this fastener. Tesla's service records for this VIN should confirm no prior work has been performed in this area, meaning the fastener has not been touched since the vehicle left the factory. Factory-installed suspension bolts of this type are typically secured with a locking mechanism or thread locker; a properly installed nut does not detach through normal vehicle operation. This constitutes a safety defect. A rear subframe fastener that was not properly secured at the factory could lead to suspension component failure, loss of vehicle control, and a serious accident. Tesla's service center has denied warranty coverage for this repair despite the vehicle being within its warranty period, citing that "a manufacturing defect would have presented itself earlier" and that because I am not the original owner, they "don't know what might have happened." Tesla quoted $2,812.49 to replace the damaged rear subframe assembly.
