NHTSA Complaint #11481593 — 2021 ACURA RDX

What component or system failed or malfunctioned? Car automatically applied brakes on several occasions, despite no obstacles in front of the car. Incident 1: While driving through an 3-way intersection, the car slammed on the brakes automatically. There was a van in the opposite lane waiting to turn left. There was 2-3 feet of space so there was no risk of collision, but the car slammed on the brakes causing me to come to a sudden stop in the middle of the intersection. Incident 2: I was changing lanes to go past a stopped car in the left lane (It was waiting to make a left turn) The car automatically applied brakes, even though I would not have hit the car. Cars behind me had to slam on their brakes to avoid rear-ending my stopped car. Incident 3: While driving on a freeway at 65 mph with light traffic and no cars in front for at least 1000 ft the car flashed the automatic brake warning. It did not actually apply the brakes, but could have caused an accident considering the speed. Incident 4: While driving on a 2-lane road with cars parked on the sides of the road, the car displayed an automatic brake warning despite no collision being imminent. Incident 5: While driving down a suburban street with no trees or obstacles in sight, the automatic brake warning flashed. How was safety put at risk? Sudden stopping in a road, highway, or intersection could cause an accident. I am concerned for my safety, because if the car stops unexpectedly in the middle of the road, other cars may hit me. This is the same system used in some Hondas, so a recall of Honda vehicles may need to be extended to Acura vehicles. Has the problem been confirmed by dealer? Yes. The service advisor told me that his car has the same problem, but that it is normal and there is nothing they can do about it. Were there any warnings? Usually happens when there is a radar reflective object above or off to the side of the path of travel. The BRAKE warning appears when automatic braking is applied.
