“On December 12, 2025, I was in a head on car accident in my 2021 Toyota Corolla nightshade. I was slammed into the steering wheel which caused injury. My car has over $14,000 worth of damage to the front yet my airbags did not deploy. I have taken my car to Toyota several times over the past few years and every time I’ve asked about a remedy for this recall I’ve been told there is no remedy as early as June or July 2025 I had to bring my car in for a manufacturer defect with the engine that Toyota fixed for free. I asked them about the recall on the airbags. They again told me there was no remedy.”

“This Toyota Corolla hatchback is experiencing an issue where it is constantly giving an “ENGINE MAINTENANCE REQUIRED” light and when scanned, it says “coolant bypass valve malfunction”. There is already a recall for many Toyota Corolla Sedans experiencing this issue of this bypass valve being defective, but because this is a hatchback, it is not part of the recall when it should be. There is already a recall for vehicles affected with this issue: T-SB-0112-24”

“The vehicle displays an “Engine Maintenance Required” warning message shortly after the air conditioning is turned on. The warning does not usually appear immediately at startup but consistently appears when the A/C system is activated. The vehicle currently remains drivable, but the issue appears related to the engine cooling system and may involve the coolant bypass valve/flow control valve, which has been widely reported by other owners of similar model vehicles. The problem raises safety concerns because a cooling system malfunction could potentially lead to overheating while driving. The issue has been reproduced multiple times. A generic code scan at an auto parts store did not show stored engine codes. The vehicle was taken to a Toyota dealership and Toyota customer service was contacted regarding known coverage programs related to this issue, but the VIN was reportedly not included. Warning symptoms first appeared during normal driving and continue intermittently whenever the air conditioning system is used.”
