NHTSA Complaint #11704120 — 2018 TESLA MODEL X

I own a 2018 Tesla Model X 100D. The high-voltage battery has failed twice in seven years. Tesla replaced both with re-manufactured batteries. My battery warranty ends in December 2026, and if it fails again the replacement cost is about $17,000. The car’s full-charge range has also dropped from over 300 miles when new to about 220–240 miles. The value of the car has dropped to around $24,000, largely because of battery issues and the risk of future failure. A high-voltage battery should not be failing this often. If it fails again after the warranty expires, the car is not usable or safe. I believe this may affect more owners than Tesla acknowledges. I am requesting that NHTSA review the safety and long-term reliability of Tesla’s high-voltage batteries and the re-manufactured replacements.
