8. Description of the defect and risk to motor vehicle safety:
Tesla has not determined that a defect exists in either the Front Suspension Aft Link or the Rear
Suspension Upper Link and believes the root cause of the issue is driver abuse, including that driver
usage and expectation for damageability is uniquely severe in the China market. If the customer inputs an
abuse load (e.g., curb impact, severe pothole strike, etc.), then the parts may be damaged, leading either
to immediate failure or delayed failure from the compounding effects of the initial abuse and subsequent
load input.
Tesla has also not determined the existence of an unreasonable risk to motor vehicle safety. The
occurrence of such failures in China (approx. 0.1%) and elsewhere (less than 0.05%) remains
exceedingly rare and if a failure does occur, it is immediately apparent to the driver. For the Front
Suspension Aft Link, a full separation typically occurs at low speeds and high steer angles, most often
when the vehicle is in reverse. For the Rear Suspension Upper Link, the vehicle remains controllable after
the part has completely separated. Finally, Tesla is not aware of any crashes, injuries or deaths, or fires
related to this issue.
