“I drove the car at 40mph through about 2 inches of standing water. This caused the undercarriage splash plate to become loose. It has not fallen off, but it will need to be repaired. The streets sometimes flood and none of the cars I’ve owned ever had this happen.”
NHTSA complaint #11650708, filed 2025-03“While driving on the highway under normal conditions with no road hazards present, the engine under cover (part #51441-42210) detached from my vehicle and the bumper clips broke, causing both the under cover and bumper to become damaged and requiring replacement. There was no collision, no debris, no pothole, or any other road hazard involved. The failure occurred solely under routine highway driving conditions. Upon taking the vehicle to my Toyota dealership, the service team acknowledged this is a known and recurring issue with the bZ4X model. …”
NHTSA complaint #11733142, filed 2026-04“I drove my 2023 TOYOTA BZ4X home from work after a heavy rainfall in Galveston, Texas in January 2024, had about 2-3 inches of rain on the road, driving about 15-20 miles per hour on my way home. Both front wheel wells/mud guard liners came off. I drove over one of the liner, stopped and picked it up. Also a liner in the back of the car's undercarriage was hanging out. Took the car to the dealership the next morning and was told since it's due to external force/rain. The warranty on a 6 months old car is not covered. Called Toyota cooperate office and was told the same thing. …”
