Automatic Emergency Braking problems of the 2022 Hyundai Elantra

The emergency braking system activated and began slowing down the car on two occasions: sometime in the fall of 2022 and on 09/01/2025. In both instances, I was driving about 65mpg on an interstate. There were no cars in front of me to cause the system to activate.

While driving highway speeds (65mph-75mph) the emergency braking system randomly activated causing my car to slow to almost a halt and swerve itself in the middle of the highway almost causing multiple accidents. It has happened 2-3 times over the past 2-3 months. Brought to a dealer and it could not be "duplicated" so I was sent on my way worried about this car.

All safety features randomly appear and go off as well as while driving 80mph down the highway the speedometer and rpm gauge both dropped to zero. Vehicle has been at the shop multiple times and stayed for three months where they could not duplicate the issues. I have pictures and videos of multiple instances. Dealership replaced back up camera and was told that was the cause for the safety lights going off and within a week of getting vehicle back the forward collision light has come on two different occasions when no vehicle is around as well as two instances when a vehicle slammed on brakes in front of me and the front collision sensor did not go off at all.

Automatic emergency braking appears to be getting falsely triggered. This happens when I am pulling out of parking spaces, even with nothing besides or behind me. This also happens when cars in lanes beside me pass me.

I was traveling on a road headed to east bound 1-80 when my aeb engaged and it caused me to swerve to the left and the aeb slammed into the braking system. It lasted about 30 seconds and then clicked off and did not do it again until a few days later when traveling on the same road the aeb engaged again at the same spot causing my vehicle to swerve to the left. It then did it a third time while traveling in town at 45 mph the aeb slammed into the braking system for about 20 seconds and then released. It was very scary and not provoked as this could cause a very severe accident if not fixed.

I was driving down a highway at around 60 mph with no one around me. As a car started to pass me on the left, my Elantra started sharply turning to the left and stopping. The dash started beeping with emergency braking lit up. The system activated on its own for no reason.

On 2/26/2022, while driving east bound 134 at night. Aeb of my 2022 Elantra kicked in. The first time aeb kicked in hard and I lost control of the car for a split moment. The warning sounds as the aeb activated and I swerved slightly (within my lane). This happened while I still had sufficient safety distance with the car in front of me and before the car in front of me began braking. The second time this happened was 10 minutes later, when there were no cars next to, behind, or in front of me. Same thing happened where aeb suddenly activated under normal driving condition. The vehicle is available for inspection upon request. This sudden braking puts me, my passenger, and car(s) behind me at risk. Potentially this puts cars next to me at risk too. The problem is currently under inspection by the dealer at cardinale Hyundai in corona, CA. Dealer so far has notified me the problem was unable to be reproduced and did not find any system or parts out of the ordinary. The vehicle has not been inspected by the police or insurance. This is a brand new 2022 model Elantra purchased on 12/31/2021. There were no prior warnings lamps, messages, or other symptoms prior to the failure. Dash cam video clips of both incidents are available upon request.
