Was driving into the garage (coasting) very slowly and as I was preparing to step on brake the car revved forward unsuspectedly - I have a video on my ring door bell and you can hear the engine then the squealing of the automatic braking system. I destroyed the adult 3 wheel bicycle that was stored along the wall but that helped the vehicle from crashing through the bricks - I remember shouting “what the hell is happening”. After much research as I knew I did not depress the accelerator in error - I found that this has been a common occurrence with Toyota and Lexus products. I am a very careful driver and I have replayed the incident in my head over and over. I presently dont have the insurance and repair information Readily available

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Lexus Rx450h verdict →
