I do not know what component or system failed. I was at an appointment with my son when the receptionist informed me that my car alarm was going off and there was smoke coming out of it. I went out to investigate and it sounded like the engine was attempting to start continuously. My key fob would not unlock the car. The engine continued to attempt to start and i was certain the car was going to start fire. We called 911 and went back inside to avoid anyone being hurt. The car then caught fire and burned until the fire department put it out. It was towed to an impound lot where it caught fire again and was destroyed. See pictures for more information.

I noticed a crack forming in the windshield without seeing any signs of an impact. I took it in and Toyota had found a small indentation along the crack line that they claimed to be what caused the crack. This indentation along the crack line was superficial and did not have any of the "spider legs" type crack lines out of it. I have had older vehicles in the Pacific Northwest without this issue, and I thought this was odd so I took it to a 3rd party Master Window repair technician not associated with Toyota and they diagnosed it as a stress crack related to the heating element.

Imperfections in glass (all windows) which cause visibility problems in the daytime and nighttime driving. I have reported this to Toyota customer service center. A Toyota inspector has inspected the glass and Toyota refuses to correct this problem. I have had several glass company's and auto detailers look at the glass and they have told me that it is a factory defect.

Vehicle has constant transmitted engine vibration in steering wheel. Vibrations are causing tingling, numbness and joint pain. Vibrations are worse with increased engine RPM. Vibrations have been constant since car was purchased new in April, 2018. Car has 2400 miles on it currently, 5/23/18. Long trip (900 miles) was first time there was tingling and numbness which were unbearable at the 450 mile mark and the return trip was quite distracting and uncomfortable to say the least. For 2 weeks afterwards, tingling and numbness remained. Now after approx. 3 weeks, it takes about 10 minutes of driving for the tingling and numbness to return now feeling mild joint pain as well. Vehicle has been brought in for repair 3 times so far for this condition and the dealer and Toyota refuse to acknowledge the condition! I have already scheduled the 4th. Appointment at the dealer so I can commence my arbitration/lemon law claim. I purchased a vibration analyzer and the readings off the steering wheel far exceed safe recommended vibration levels established by N.I.O.S.H, /O.S.H.a. by a factor of at least 3 to 4 times! if I keep driving this vehicle it will turn into a personal injury lawsuit vs. A simple lemon law claim.

Toyota "all weather floor liners" are collapsing at the sides and becoming a tripping hazard. Toyota part number PT908-89160-02. Within week of buying new car, the floor liner on passenger side was collapsing on the sides. Reported to dealer. He checked with Toyota rep and was told it was not under warranty. We contacted the sales manager at dealership, he bought use new mats. Within six days of new mats, the same problem began again, see picture. Since Toyota has a history of floor mat issues, one would think this would be a be concern to them, apparently not.
