My foot was on the brake but the car lurched forward at about 25 mph and rammed into the car parked in front of me, crunching his rear tail light and bumper and damaging the front of the passenger side of my vehicle. As soon as my car hit the car in front of me, it stopped.
What component or system failed or malfunctioned, and is it available for inspection upon request? My Lexus 2020 UX200's brake malfunctioned and caused a crash accident into a restaurant on February 29th. It was inspected by Lexus Liability and an independent mechanic on March 13th, 2024.
The contact stated that while driving approximately 40-50 MPH, the sunroof shattered without impact.
