2017 LEXUS RX — SEATS

NHTSA Safety Complaint – Seat Heater Defect Vehicle: 2017 Lexus RX 350 Mileage at purchase: 45,430 Purchase date: Feb. 17, 2025 Dealer: Lexus of Tacoma at Fife, WA Description of Problem: The driver’s seat heater does not function properly. It is slow to activate (5–6 minutes), then overheats uncontrollably even when set to “LOW.” On multiple occasions, the seat became hot enough to cause burns through clothing. Defect Confirmed by Dealership Service Staff: Dealership staff confirmed that the driver and passenger seats heat at different rates. This matches a known defect identified in Lexus Technical Service Information Bulletin L-SB-0038-18 (Oct 10, 2018). Additionally, they confirmed that the drivers' seat spikes to uncontrolled high temperatures, even on the "LOW" setting. Despite this, the dealership refused to repair the issue without an extended warranty and suggested using a sheepskin seat cover to prevent further burns, which is prohibited in the vehicle manual. Safety Hazard: •The defect caused burns to the driver. •The driver's elderly mother, who has peripheral neuropathy in her legs, did not feel when the passenger heater was accidentally turned on, highlighting the risk of undetected burns should the heater defect remain unrepaired. •Risk of fire is also present given the uncontrolled heat and inherent electrical issue. Attempts to Resolve: Reported to dealership on 3/28/25. Dealer disclaimed responsibility. Reported again to dealership on 6
