While driving our Lexus on 8/13/2023 on the interstate under normal driving conditions ALL of our warning lights came on one after another. We also lost air conditioning and power brakes it seemed. We immediately exited and pulled over. Opened the hood and the engine caught fire and fully engulfed the engine compartment. From the time of the first warning light to the vehicle being engulfed was probably 5 - 7 minutes. The vehicle was deemed a total loss. We filed a product liability claim with Lexus/Toyota and they investigated the vehicle on or around 8/28/2023 and were not able to determine a cause of the fire. Because they could not determine a cause our claim was denied. Our car was perfectly maintained and only had 15,000 miles on it at the time of the fire. We bought this vehicle new almost two years to the day of the fire and believe the fire was caused by a defective part. We understand it is very difficult to determine the cause of an automobile engine fire. Other comments below: We do not know where the vehicle is now as there was an insurance claim and the insurance company only held it for 30 days. Our safety and the safety of others was at risk luckily no one was injured. Problem has not been reproduced or reviewed by an independent service center. Vehicle was inspected. All electrical warning lights came on
