On the morning of July 21st the vehicle was parked in the garage the night before when all of the sudden our neighbors were yelling at my wife and I to exit the house because they saw fire flames and black smoke coming out of the garage. Everything in that garage and part of the house was destroyed. After it was safe to enter the house we noticed the damage was concentrated where the Toyota was parked, the explosion from the engine caused the hood to almost touch the windshield. Half the engine was gone.
While turning left out of a drive through my the steering locked up and shot to the left causing a run up on the curb. However after a second or two it cleared. Upon shutting the car off and restarting driving in a parking lot same problem occured steering wheel shot to left causing me to almost loose control then all electrical power was lost in the vehicle. The steering wheel fault came up on the dash and would not let me control the wheel.
Odometer Fraud. The contact purchased a 2017 Toyota Corolla. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 81,456 and at the time of registration, it was discovered that the mileage was 257,000.

While reversing out of a parking spot, I noticed my break and steering wheel felt extremely stiff. I lost control of the vehicle for a second until I instinctively pushed HARD on the break. I realized it was unsafe to continue reversing, so I switched from R (reverse) to D (drive), I let go of the break pedal slowly, but the car continued to reverse. I pushed hard on the stiff break again, and switched from D (drive), to P (park), I let go of the break pedal again, and the car continued to roll back in reverse still. I realized my cars breaks, steering wheel, and gears were being unresponsive. I kept my foot on the break pedal, used the parking stick and set the car into P (parking) again, and turned it off. The car did not roll back as before, and was completely off. I turned the car back on again, and it went back to normal. …
The car was in a traffic jam, when the car automatically turned off and the control panel started to display the battery signal. This event occurred when the car was in the middle of a road. The car was pushed by other person to a safety area and then it was turned on. This situation never happened before. The vehicle battery is practically new and after the incident, the battery signal (lamp) has not been activated. The vehicle was evaluated by a Toyota authorized dealer, cleaning the combustion system, but there is uncertainty that this situation can occur again. A car that automatically turned off in the middle of the road is a safety issue for the driver and passengers, and also for other drivers.
I reached out to the manufacturer several months ago about the recall and was told to wait for them to order the parts to fix it. I waited and reached out again and nothing has changed. I am not sure how to get to this recall fixed without the cooperation of the manufacturer.
While coming to a stop at a stoplight, a car come out if no where. I tried to slam on the brake to come to a stop faster but the breaking system did not react to the pedal being pressed down. I was met with a stiff pedal and I could feel the brakes pushing back which caused me to hit another car that had already entered into an intersection.
While driving warning lights on dashboard lit up and car shut down.according to screen on dash it showed malfunction of airbags, ABS, lane change warning, among other system parts. Able to restart car and drive it to dealer. Toyota notified me that squirrels had eaten the main wire harness. Not covered under warranty. I did some research and found out Toyota and other auto manufacturers use soy based wiring and wire covers which draw all types of rodents to them and they destroy the main harness electrical parts to malfunction. This can cause dangerous situations while driving possibly causing accidents resulting in injury or death. Brakes May fail ,air bags May not deploy etc. Toyota knows of the problem but refuses to correct it. It cost me $5000.00 to repair and I still do not feel safe. I notified Toyota corp. Office they took my complaint and said nothing could be done about it. …
