Fuel/propulsion system

5 reports
“While I was driving on the highway in cruise control, my car suddenly broke the cruise setting, slowed down, and the check engine light turned on. I pulled over and the car would not accelerate to over about 15-20 mph. I made it to an auto center, where they informed me that the reader said there was an issue with one of the fuel pumps. I am aware that there is a recall on fuel pumps in this model of vehicle and I believe that I experienced this defect.”

The dash cam confirms my speed was 70 mph and I was slowly passing the tractor trailer, with a car approximately 4 car lengths in front and another car approximately 4 car lengths behind. When my car passed over a small road seam (evident in the video) my brakes immediately locked up with no input from me (confirmed by EDR data). The car started to veer into the right lane and I corrected the car to the left, at which point the car began to rotate while on the highway, continued into the median, and after a 360 degree rotation came to rest and shut off automatically. This occurred the day after I had a comprehensive 120,000 mile inspection done by Lexus. Lexus has been almost completely unresponsive despite having had 2 technicians examine the car. I was told I would hear from Lexus by October 8th, it is now November 3. I commissioned forensic engineers to evaluate the Event Data Recorder and their conclusions are as follows: 1. The EDR…”
