Service Brakes problem #1

On April 1, 2026, while pulling into a parking space at our church, I was applying the brake when the vehicle suddenly and forcefully surged forward without warning. The unintended acceleration was intense and unexpected, occurring despite continuous braking input. This resulted in the vehicle striking the building and causing significant damage to both the vehicle and the structure. This incident has occurred twice within a 10 day period, both times during low-speed parking/stopping maneuvers. There were no warning lights, alerts, no automatic emergency braking engagement, no air bag deployment, or prior indications of malfunction. I did report this to the police and they filed an incident report. Lexus was notified and an independent analysis engineer examined the data from the vehicle's cdr system. This report was sent to me and to Lexus.
