2021 Acura RDX Forward collision avoidance Problems

“While accelerating off the entrance ramp onto the highway, The engine randomly slows down automatically…the car reduced speed drastically without applying brakes and without cars around me or in front of me.”

“Purchased my 2021 in November of 2020. Two weeks after, i was driving with adaptive cruise on at 65 mph on a freeway. 100 yds ahead i could see a diesel going slower than i, so i looked and saw no one coming at all, so i moved over to the passing lane. I got 5 feet into the lane and the car slammed on its brakes, on its own!!! Thank god no one was behind me or i might have died!! I reported this to Acura within 1 week, and then reported it to DOT the next week. I own one of the first 2021 s made, so i didn’t see a lot of feedback. …”

“On 3 separate occasions my Collision mitigation braking system has malfunctioned. The first time I was driving at 55 with my cruise control set with no cars in front, behind or beside me when, without warning or reason, the orange brake light abruptly flashed on my front dash panel and my car abruptly stopped in a whiplash manner.

The car slammed on the brakes so hard the seat belt restraints engaged as we flew forward, enough so that my wife and I were both sore the next day. Items on the back seat flew onto the floor. If there had been a car behind us we would have been rear ended and potentially a multi car pile up. …”

“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. …”
