What owners say
Unexpected sudden acceleration (when braking) as I was slowing down from exiting a highway, just as I was approaching full stop, it felt like the regenerative braking stopped grabbing momentarily and I violently lurched forward for what seemed like a feet or two. I thought it was a fluke back then and thought nothing of it. It just happened again today as I approached a stop sign - again as I neared complete stop with brake depressed it felt like the brake stopped working for a second and the car again lurched forward violently as if I had lost control for what seemed like a foot. Would have hit the car in front of me if there was one.
While braking at around 15 mph there is a sudden loss of braking force that causes the car to surge forward. This happens as the car switches from regenerative braking to pad braking. It has almost caused an accident a few times for me.
Experienced it a number of times intermittently. When making a stop from about 25-30 mph, just before making a full stop (~10mph) while foot on the break, the vehicle lunge for a split second. The feeling of loss of braking power. At number of times, I thought I was going to rear end the veh in front of me. The last time I experienced it was last Aug 7.
Our 2022 Hybrid Toyota Sienna will randomly have a loss of brakes for several seconds while in the middle of a stopping situation. The vehicle seems to lurch forward with the brake pedal going soft. After cramming my foot as hard as possible into the brake pedal I have been able to get it to stop so far, however my stop distance is much longer than anticipated. It seems to be getting worse in the past week with 2 of these episodes occurring. In the past year it has happened approximately 5 times. Each time is highly distressing. We have taken it to one Toyota dealership so far that could not find anything wrong with the brakes and have another appt in July with a second Toyota dealership. I find similar experiences described online from other 2022 Hybrid Toyota Sienna owners. I feel an obligation to report this because it is life threatening to be without brakes for even a few seconds while driving. There are no warning messages that appear when this brake failure occurs and it has not been reproducible.
