NHTSA Complaint #11681856 — 2014 TESLA MODEL S

Vehicle Information: 2014 Tesla Model S VIN: [XXX] Incident Date: [XXX] Component Affected: Suspension / Air Suspension / Ride Height Control Problem Description: On [XXX], while driving, my 2014 Tesla Model S suddenly raised itself to and/or beyond maximum ride height without any driver input. Immediately afterward, the front driver-side suspension collapsed completely, leaving the vehicle unsafe to operate. This appears to be an uncommanded overinflation event caused by Tesla’s suspension control system. It is not normal wear but a manufacturer-induced malfunction. If this failure had occurred at highway speeds, it could have caused catastrophic loss of control. The collapse of a suspension system without warning is a serious safety defect. Tesla’s service center in Moraine, OH, has refused to review the vehicle logs (which would confirm this sequence of failure) and has instead classified the incident as a standard part failure. As a result, Tesla is attempting to push full financial liability onto the owner instead of addressing what is clearly a safety-critical defect. Safety Concern: A sudden, uncommanded suspension height change followed by collapse could lead to total loss of vehicle control and a crash. This poses an ongoing risk to both Tesla drivers and the public. Requested Action: I am requesting that NHTSA investigate this failure mode as a safety defect in Tesla Model S vehicles and require Tesla to address these failures appropriately.
