“I was driving on the interstate at about 65 MPH. It was raining. I needed to accelerate quickly in order to avoid a car that was trying to merge into my lane. When I hit the accelerator, the car cut off. This caused me to loose speed and almost have an accident. I had to restart the car to get it back into drive.”

NHTSA complaint #11373083, filed 2020-11, 32,000 miles

“Uncontrolled acceleration in the two episodes that I described to the dealer when I brought the car in for service, I was unaware of the acc feature. I had not yet, and have still not, used any cruise control or acc. #1. I was in a parking lot of a costco. I had just started the car, backed out of a spot, and proceeded to the end of the row, where I would now turn left onto the main 2 lane (1 in each direction) feeder into the parking lot, from the public street. …”

“My brand new 2019 Acura RDX that had 9200 miles on it shut down on me on the freeway. It was raining and I pulled out to pass, going about 75 MPH, and it went into what I now know is limp mode and the engine light flashed on and off and the engine was making a different sound than normal. I had someone tailgating me, so I am lucky it didnt cause an accident. Got pulled over and called the dealership and they said it needed to come in. They speculate raindrops got on the engine filter (forget the name) and the car thought it was malfunctioning and shut down. …”

“Driving vehicle est 40mph, straight road city right lane. Car ahead of me (est 2 + car length) turned right,and was no longer on the road I was driving, my vehicle slowed down. I did not press brakes or change drive to neutral. There was no input from me to change vehicle speed. Space reserved bars use radar to keep designated space. There were no bars for a safety margin. No lights or indicators display on dashboard for reason of deceleration. Normally if I am close to a person who is turning off the road, sensors may detect than and flash brake on the dashboard. …”

NHTSA complaint #11325184, filed 2020-05, 16,500 miles

“Lkas system is dangerous - will pull to the right then shift to left dramatically and then overshoot markers. Will take you off the road, car will not stay in the correct lane. Does not recognize double yellow lines and cuts right across them, sometimes unexpectedly. Pays no attention to them driving on a 8 lane highway, in the fast lane with cruise control on. I am passing a car/truck going slower in the next lane to my right. All of a sudden, the car just hits the brakes and sounds an alarm. Very dangerous, can be hit from behind due to sudden unexpected braking. …”
