It's been reset but same problem.”

“So while driving my car, no car infront of or anything running out in the road. Going 45 mph my car automatically slammed on brakes by itself. Causing the car behind me to swing around me to avoid hitting me in my rear. A similar situation happened back in May 2023 resulting me to put the car in the shop & was told it was corrected.”

“I was traveling at about 40mph when my vehicle, with no traffic in sight, had the automatic emergency brake go off and reduced my speed to 32mph. My safety concern is what if this happens on the freeway or even while raining. if there was a car behind me what if it caused them to get road rage. ***dashcam video available***”

NHTSA complaint #11555856, filed 2023-11

“I brought this car in January 2023 and the Forward Emergency Braking keeps popping on while driving. There are zero cars that were in front of me. This is the 4th time this has happened. With the last 2 incidents happening within the last 24hrs . 10/21/23 & 10/22/23. This is issue that may cause accident.”

NHTSA complaint #11551243, filed 2023-10

“My car has been hacked. I know the hacker was able to get my VIN number bec he hacked my computer also (and I had to enter the information to setup autopay etc through my finance company). The hacker has been messing with the brakes which makes me afraid that it will force me into an accident. He is also messing with my RPM (I believe): there's resistance when I'm accelerating.”
