NHTSA Complaint #11690162 — 2025 TOYOTA GR COROLLA

The car randomly reports an Engine Malfunction which results in many warning lights indicating that certain systems are non-functional. These include (but are not limited to): - Forward collision warning - Automatic emergency braking - Cruise control - Basically, any driver assistance feature that requires external sensors is turned off Also, the rear wheel drive is turned off so the car only drives using the front wheels. On each successive drive, with the engine turned off in between, some of these systems start functioning again. After 3 or 4 such driving cycles all the systems come back on. The dealer detected error code P2C90 (P2C9000) which refers to the positive crankcase ventilation system. The ventilation system was inspected and nothing was found to require repair. Others have reported this issue: - the video here shows the dash warning indicators: [XXX] - this person had to use the lemon law to return the car to Toyota [XXX] It is crazy that an errant emissions error disables the safety assistance features of the car.
