This page covers 6 recalls and 19 owner complaints for the 2021 Toyota Supra.
Electrical system complaints make up the largest share of what 2021 Supra owners report, with several describing concerns serious enough that they disconnected the battery or parked the vehicle outdoors as a precaution against fire risk. A smaller but notable group of owners report engine-related issues, though the specifics vary across those complaints. One recurring electrical symptom involves brake system warning messages appearing intermittently, including critical stop-driving alerts, with owners describing multiple dealership visits without a resolution. On the HVAC side, at least one owner reports a blend door actuator problem causing the driver's side to blow cold air while the passenger side stays warm, with heat only functioning properly at the highest temperature setting.

By System
The 2021 Toyota Supra has 6 recalls, the most serious being two separate fire risks: a starter relay that can corrode, overheat, and short circuit, and a fuel tank weld that can fail and leak fuel near an ignition source. The starter relay issue can occur even when the vehicle is parked and turned off, and one filing notes it specifically affects certain 2.0L-equipped vehicles. On the engine side, a software issue in the engine management system can cause a loss of brake assist during startup, though full mechanical braking remains available. There is also a seatbelt concern: a faulty retractor can fail to hold the belt correctly in a crash, raising the risk of injury to the occupant.
