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.

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.

I WAS AT A STOP SIGN IN MY 2020 HIGHLANDER WAITING TO TURN LEFT ONTO A BUSY ROAD. UPON TURNING LEFT ONTO PA STATE HIGHWAY 999, THE HIGHLANDER ENGINE TURNED OFF AND THE STEERING WHEEL WAS "LOCKED" INTO A LEFT POSITION. THIS CAUSED THE CAR TO CONTINUE TURNING INTO THE OPPOSING LEFT LANE RESULTING IN A HEAD-ON COLLISION WITH AN ON-COMING CAR. WITH THE ENGINE TURNED OFF THERE WAS NO POWER STEERING, NO BRAKES, AND NO WAY TO UNLOCK THE STEERING WHEEL. THE COLLISION CAUSED MY CAR TO BOUNCE BACK AND SLOWLY FREE ROLL BACK TO THE STOP SIGN AS THOUGH I NEVER ENTERED THE ROADWAY.

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 Toyota Highlander verdict →
