3 Engine And Engine Cooling problem

Failure Date: 05/21/2024

Spontaneous vehicle fire: while driving approximately 20-30 miles per hour, with no other symptoms or advance warning signs, a message suddenly appeared on the dashboard saying "engine failure - turn off ignition". The temperature gauge was firmly in the normal range; the car had been inspected a few months prior, and had recently had routine maintenance. There was no indication that anything was amiss before this incident. 30 seconds after the sudden warning message appeared, smoke began pouring from the hood and I immediately pulled over to the side of the road and exited the vehicle with my young daughter. The smoke continued and the entire front section of the vehicle quickly caught ablaze. Police and the fire department arrived on the scene to assist and extinguish the fire. The vehicle was towed and determined to be a total loss by insurance. Our safety was put at risk because our vehicle spontaneously caught fire with no early warning signs; if we had been driving on a highway or a road without space to quickly stop the vehicle and safely exit, we would have certainly faced injury or possible death given the speed and ferocity with which the fire erupted. After we contacted Toyota several times, they sent an inspector to look at the vehicle, and reported: "the inspector observed extensive fire damage to the engine compartment and interior of the vehicle. The inspector also observed that there was no oil registered on the dipstick. There were no arc marks on the wiring in the engine compartment when inspected. The inspector did not observe any oil leaks when inspected. The battery hold down bracket was in the proper location. The cause of the fire was undetermined, and there was no evidence from the inspection to indicate that this incident was a result of a vehicle defect. " Toyota has shown a complete lack of curiousity as to determining what could have caused the fire and has only focused on avoiding liability, thereby putting customer safety at risk.

4 Engine And Engine Cooling problem

Failure Date: 07/22/2023

I experienced a sudden engine failure while driving my 2015 Toyota Highlander on interstate 294 outside chicago. I was driving about 75 mph in the far left lane. A warning message "check awd" came on the screen, followed by the engine icon lighting up, then a "trac off" message appeared on the screen. I began to merge to the right across four lanes of traffic to get to the shoulder. As I was doing so, a beep sounded, and the message "engine stopping" appeared on the screen. The accelerator stopped working. I reached the shoulder and the car came to a stop just as I made it to the shoulder. The whole incident, from the time the first warning light came on until the car completely stopped, lasted about three minutes. Prior to this, there were no warning lights, and I had been driving the car without incident. The car had received all regular maintenance at proper intervals. Mileage was 86,100 at the time. There were five people in the car, including myself, my teenage daughter, her friend, and her friend's parents. We were driving the girls home from a summer camp. We are unharmed -- and possibly alive -- only because I was able to merge across four lanes of traffic and reach the shoulder before the engine completely failed. Just behind us and just ahead of us on this stretch of interstate, there is no shoulder. Semi trucks populate this very busy road. We had to sit on the shoulder for two hours waiting for a tow truck. We are all truly fortunate to be alive and unharmed. The vehicle is in the possession of mcgrath elmhurst Toyota, 630-279-2160. The service department has diagnosed as follows: "performed diagnostic and found codes p0300, p0301, p0302, p0303, p0306 engine misfire codes. Code p1603 engine stalls out.
