Purchased this vehicle on 7/30/2022 from Tustin Toyota, 36 Auto Center Drive, Tustin, CA 92782. I also purchased an extended warranty to cover all future repairs for an additional $2,995 call 'extra care'. I had some warning lights come on after only driving the vehicle for a few days. I brought spent for hours waiting for the dealership on Aug. 1, 2022. The diagnosis was there was nothing wrong and [XXX], Advisor, told me it was normal for Mirai vehicle when it gets low on fuel for warning lights to come on. Sunday, August 7, driving at 2:15 pm PST going only 20 miles per hour, on a side street in Mission Viejo, CA, the right side air bags deployed, there was no impact, no accident. The car was inoperable as the electronics sensed there was a collision so the driving mechanism was disengaged. I had the vehicle towed to dealership on 8/8/2022 for repairs. I was there 7 am. At 4 pm. I spoke with [XXX], Advisor, and he told me because water was found on the floor mat on the passenger side, it affected wiring that is underneath the floor mat and caused a short, which caused the Air Bags to Deploy. This is a manufacturers defect to mount vulnerable wiring under a floor mat. I have two warranties on the vehicle and neither warranty wants to pay for the repairs. If all the Mirai all manufactured with this wiring under a floor mat, there needs to be a Factory Recall and this wiring needs to re reouted to avoid major accidents. If I had been driving in a major freeway, I this issue could have caused major accidents and death of myself and other surrounding drivers, as it also disengages the ability to safely drive the vehicle. The only thing that should deploy air bags is a collision - not faulty mounting of wiring under a floor mat. I need immediate investigation and action on this matter as this may affect thousands of vehicles since 2014 made by Toyota. [XXX] Phone / Text.

On August 1, 2022, I had only owned the vehicle for a few days, purchased July 28, 2022. Idiot dash lights came on. On the dash display it told me to take it vehicle back to the dealership, Tustin, Toyota, 36 Auto Circle, Tustin, CA 92680 [XXX], Service advisor claimed there was nothing wrong, lights come on when it low on fuel. One of those lights was the RED AIR BAG LIGHT. The dealership was negligent in faulty or no real inspection. I should never of been allowed to drive the vehicle out until the air bar light was dealt with. I drove away, thinking everything was okay but lights and warning signs were still flashing. [XXX] admitted to me that he was only really in charge of tires - nothing else. August 7th I was driving 20 miles per hr in Mission Viejo, residential neighborhood. The right air bag deployed, not accident and the engine was disabled by the computer in the car. I had the vehicle towed to my home and then on Monday, Aug. 8 had it towed back to the dealership, Tustin Toyota. Service writer [XXX] had a mechanic diagnosis; water from a drink had spilled on the passenger floor mat, which shorted out the wiring and circuit board, which caused the air bag to deploy. Had I been on the freeway going 65 mpg, I would have been dead. The engine stops where there is a deployment. It is ridiculous for a car manufacturer to not build the car correctly, and mount wiring, electrical and circuit boards in areas that will not encounter liquid or food issues and the vehicle owner should Not be held responsible for their design negligence. Burying instructions in small type in an ownerâs manual that no way takes the time to read is negligent at best. The occupants SAFETY at all times should be the TOP PRIORITY. No one at Geico, my insurance company has ever heard of this happening with ANY car. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
