Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“There is currently an ongoing recall for the GR Supra over the starter. I currently drive a 2020 and have had periodic starter malfunctions. This is when I go to start the car it states starter system malfunction then lets me still turn it on after clearing the error message. I have brought this up to my dealership and due to the intermittent nature of the issue they said they could not diagnose and that continuity was good so they would not replace it and if they did it would not be covered. …”

“There was a beep and then my dashboard went completely blank (was just dark) so I couldn't see any information such as how many miles per hour I was driving or how much gas I had or my navigational information or what gear I was in. Then the dashboard came back on and it said there was reduced driver assitance (but did not say what was wrong). The dealer says my dashboard should not have gone blank but they can't fix it since not sure why. This is very dangerous and should be addressed.”

NHTSA complaint #11455413, filed 2022-03

“Rear hatch will not open electrically and/or from the interior manual release handle. If someone gets stuck in the trunk or a pet, won't be able to come out. I had items I bought and if they included battery or dangerous item, my safety would be at risk. There is no rear realse hatch button from the outside the car. NO other problems or accidents. Is there any additional weight mounted on the rear hatch (e.g. a spoiler)? No Does the latch release electrically? No 4. When attempting to release electrically, does the latch make a noise? …”

“The 2020 - 2025 Toyota Supra is manufactured by BMW and uses virtually all components supplied by BMW. The vehicle includes dual climate controls (driver / passenger) and the temperature of the air from the vents is controlled independently. It is known by BMW that the blend door or the actuator (motor) - which regulates how much cold versus hot air is mixed per the control setting - can break or be deformed. This is a manufacturing defect in the heating unit, not a wear issue. …”
