NHTSA Complaint #11683008 — 2020 TESLA MODEL Y

Problem: I purchased a 2020 Tesla Model Y Long Range AWD, EPA-certified at 316 miles. My vehicle consistently delivers only 120–150 miles per full charge, and just ~80 miles from the recommended daily 80% → 20% SOC window. This is less than half the advertised/certified range. I have meticulously logged trips since July 2025, recording start/end battery %, mileage, Wh/mi, and driving conditions. Even after following Tesla’s own efficiency guidance (Chill Mode, conservative HVAC, no Sentry Mode, no Cabin Overheat Protection, speeds at/below limits), the shortfall is repeatable. Company’s Response: Tesla repeatedly stated: No warranty action unless there is a system alert. My range loss is due to “short trips” or “driving habits.” They “cannot go off EPA numbers,” though Tesla advertises the EPA rating. To review my logs, I must pay $235/hour, while I cannot access my own internal vehicle data. On Aug 7, Tesla told me 33% SOC should equal their quoted range. In reality, I received only ~40 miles before needing to recharge. At my Aug 21 service visit, after 1.5 hours onsite, I was again told results were “normal,” despite my detailed logs showing otherwise. Why It Matters: EPA ratings are federally mandated certification numbers. Dismissing them as “not applicable” contradicts federal law and advertising practices. A consumer should not accept half the advertised range while being told it is “normal.” Charging $235/hour to access my usage data blocks validation of Tesla’s claims. What I Request: Investigation into whether Tesla is failing to deliver its EPA-certified range. Enforcement of Tesla’s 8-year/120,000-mile battery warranty, as my results suggest excessive degradation or defect. Requirement that Tesla provide consumers access to their own vehicle/battery data without fees. Written clarification of Tesla’s real-world range obligations under Arizona conditions.
