What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Additionally, the clutch emitted heavy smoke, obscuring the driver's vision and road visibility. The vehicle was towed to the dealer. The dealer diagnosed that the clutch was worn out and needed replacement due to normal wear and tear. The manufacturer was notified of the failure by phone.
The contact stated that while driving at night with the low-beam headlights activated, there was a large dark shadow at certain angles, obstructing visibility while driving at various speeds. The shadow disappeared once the high-beam headlights were activated.
Improper factory alignment leading to excessive and premature tire wear on all four tires which creates a safety issue - tire blowout. Toyota refuses to address the issue since my car is 11 months old (within their 1 year warranty period) but has 15K miles (outside their warranty period).
The car showed a message that there is a system error and many warning lights came on, including the check engine light. Most of the warning lights indicated that many of the car's ADAS functions were disabled. The car also switched from AWD to FWD.
Driving my car normally when, at around 3,800 miles, my car threw a CEL and went into limp mode, while in traffic. I had to pull over safely, immediately shut off vehicle and have it towed to the dealership for diagnostic & repair. The code was the infamous P2C90 Crankcase ventilation leak check engine light code.
Hello, Today (01/21/2026), on my 2025 Toyota GR Corolla vehicle (odometer 5243 miles), after 3200 miles of driving with the updated engine control unit (ECU) as of 10/14/2025 according to the T-SB-0071-25, a P2C90 error appeared again with an Check Engine Light.
