2025 TOYOTA GR COROLLA — Complaint #2168650

Open-data reference.

NHTSA Complaint about FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL filed January 21, 2026

NHTSA complaint #2168650 (ODI reference 11712533) concerns a 2025 TOYOTA GR COROLLA and was filed on January 21, 2026. The owner reports the failure occurred on January 21, 2026. The report was geocoded to Washington based on the filer's self-reported location. The affected component is categorized as forward collision avoidance: adaptive cruise control, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.

The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.

Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same TOYOTA GR COROLLA cohort independently describe similar forward collision avoidance: adaptive cruise control failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2025 TOYOTA GR COROLLA shows the complete component-level complaint distribution alongside any active investigations or recalls.

Complaint Description

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. This happened during acceleration while entering the highway, when the engine speed reached between 3000 and 4000 RPM. This situation disables many of the vehicle's active safety systems (all-wheel drive, vehicle stability control, traction control, adaptive cruise control, lane keeping assist, etc.), exposing owners to unwarranted safety risks due to unexplained fluctuations in the crankcase ventilation monitoring system of a new and otherwise healthy engine. How can we get Toyota to release a better ECU firmware update to fix this problem? Obviously, the previous fix was not effective enough. Regards!
