2023 Hyundai Elantra Hybrid: lane keeping assist jerks the wheel

Filed Feb 25, 2025 · Brakes, Steering · CA

UNKNOWN I had the lane assist feature on and was taking the second lane from right to turn off to exit when the alarm went off, the wheel turned itself and it started braking. There was nothing where it was trying to avoid and actually almost had me run into another by turning me left back onto the freeway while trying to stop. It’s never happened to me before and I take that way regularly.

Since 2/2/24 13 episodes of all safety features failing including blind spot monitor, lane keep assist, forward collision warning, and others. Last occurrence on 8-8-24. On one occasion the car failed to accelerate in the middle of an intersection, the car did move slowly and operation returned to normal after turning off the car and pressing the 12V reset button. Diagnostic codes found on car APP include both C164286 and C164202 for all 13 episodes. Despite being told this code is "for the speed sensor because it saw a voltage drop from the battery system" the dealer claims there is nothing they can do because they can't recreate the problem. This is highly dangerous to my family and others as the safety features can prevent accidents. The most concerning is the car suddenly losing acceleration as this could potential happen where there is no safe way to get off the road in time prior to an accident. This loss of acceleration has been reported by many other people on the Facebook group I am a part of called Hyundai Elantra Hybrid Owners. The loss of safety features occurred after all recalls were performed as of 8-8-24

While driving down an interstate at approximately 58 miles per hour, I turned on the cruise control and went to adjust it to 65 miles per hour. The car rapidly accelerated and it appeared on the dash that the cruise control defaulted to 110 miles per hour, which appears to be the maximum on the system. I tried to turn the speed down, but the cruise control would not go below 110 miles per hour. I immediately deactivated cruise control and continued to drive at normal speed. I tried multiple times thereafter to set cruise control, and it would again, rapidly try to accelerate the car to 110 miles per hour and would not let me decrease the speed. After stopping at a rest stop, turning the car off and on and driving again, it appeared the glitch was fixed and I was able to operate the cruise control normally. Please note that the "adaptive" part of the cruise control, including steering assist/lane departure worked fine the entire time.

There have been multiple occasions, both on highway and urban roads, when the Lane Keeping Assist system has forced me out of my lane, both taking control of my car's steering wheel to move me out of the lane while also failing to trigger my Lane Departure Warning. One time, LKA jerked over into a lane of oncoming traffic, another time it jerked me out of my lane into a near collision with a concrete lane barrier, and another time the LKA jerked out of the lane almost into a curb.
