NHTSA Complaint #11711522 — 2023 TESLA MODEL Y

I am submitting this complaint to escalate a safety-related concern involving premature and abnormal tire wear on my Tesla Model Y, which has not been adequately addressed by Tesla. I purchased my Tesla Model Y in [Dec, 2023]. Within less than one year of normal driving, all four tires wore out significantly and required full replacement on 08/30/2024. The vehicle has been operated under normal city and highway conditions, and Tesla-recommended tire pressure was maintained consistently. This level of tire wear is well below reasonable tire life expectations and raises safety concerns, including reduced traction, increased stopping distance, and the risk of tire failure. After replacing the prematurely worn tires at my own expense, I reported the issue to Tesla Service and requested that the vehicle be inspected to determine whether alignment, camber, or suspension issues contributed to the abnormal wear. Tesla indicated that an evaluation would only be performed if I agreed to pay for diagnostic services, rather than proactively inspecting the vehicle for a potential underlying defect. As a result, no documented root-cause analysis or corrective action was provided at that time. During a later Tesla service visit for a separate suspension noise concern, Tesla replaced multiple front suspension components (including control arms and lateral/compliance links) and performed a four-wheel alignment under warranty. These repairs occurred after the tires had already been replaced, which created doubt as to whether the suspension condition at the time may have contributed to the earlier premature tire wear. Because the suspension was not evaluated when the abnormal wear occurred, the underlying cause remains unresolved. Replacing tires alone without timely evaluation of possible contributing suspension or alignment issues does not adequately address the associated safety risk.
