Was following a truck that was pulling a utility trailer. We had just stopped and started moving again when when he suddenly stopped. I had just sped up maybe going 10 to 15 mph when I applied my brake, the brakes did not engage until after I hit the trailer in front of me and jammed it into truck it was being pulled by.I had front end damage and radiator damage and the car was not drivable. I had noticed previous to this that at times at low speeds the brakes would not engage and would need to be double tapped to get them to engage. Could go weeks without it happening or could happen multiple times in a day. No consistency to the issue.

The Pre-Collision System with Pedestrian Detection is a good thing, but there's a problem. It stops the car too abruptly on the highway, leading to rear-end collisions. When you release the brake pedal, the car remains stationary. To get it moving, you need to press the accelerator pedal. There have been four instances of the Pre-Collision System with Pedestrian Detection being activated in the last 12 months. Two of them ended in rear-end collisions. In the other two cases, there were no cars behind.
We were behind a vehicle that had come to a rolling stop because the vehicle in front of him had hit the person in front of him , we were going about 25 miles per hour and about 2 car lengths from him . I applied the brakes but the vehicle failed to stop . It was as if I did not press the brakes at all. We rearended the person in front of us . The person behind us hit us as well . It was like we were on ice but we were not .
My Toyota Highlander is a hybrid and there is an ongoing problem with the brakes under certain conditions. When you are slowing the vehicle down, with your foot on the the brakes, there is a point under 10 miles an hour, where the brakes appear to let go and you must quickly exert dramatically more pressure on the brakes to stop the car. Fortunately it has not resulted in an accident because my wife and I are aware of the potential danger. The danger is, this occurs when you are stopping at a stop sign or crosswalk, pulling into a parking space, or around pedestrians, even pulling into our garage. I have own previous Toyota Hybrids and this vehicle behaves very differently. In my opinion the route of the problem may be the regenerative braking. …
I was told by oxmoor dealership I had to talk to toyota corporate before I could get my car touched and that I did not need to talk to a lawyer. I called. Prior to the accident, the vehicle had been exhibiting multiple symptoms: an intermittent airbag warning light had illuminated briefly on the dashboard on a few occasions, and the vehicle had begun requiring noticeably longer physical distances to come to a complete stop at traffic signs and lights when not using cruise control. The vehicle was experiencing regular phantom seatbelt warnings-dinging as if a passenger was unbuckled when the seat was completely empty. The phantom seatbelt warnings i didnt think we're a big deal were occurring across multiple seating rows simultaneously in front and back. Directly preceding the crash, while making a turn, the vehicle swerved slightly. …
During the first 20K miles of driving our 2020 Highlander Hybrid; we noticed that while braking; the car would sometimes lung forward as though we had accelerated quickly. It startles you and it causes you to "hit the brakes" quickly. It doesn't happen all the time. It seems to occur more so when we're braking at low speeds in parking lots; while slowing down on a slight decline or simply making a turn left or right while braking. I mentioned this to my Toyota Dealer a few times as to whether or not they had a recall notice for this. I was told "no". I had my oil changed on June 15, 2022 MIL/35,379 and I asked them to check this problem. They checked and advised no problem was duplicated and the invoice stated in part "will wait on any diagnostics at this time". I was never contacted with a "fix". …
