2023 Hyundai Tucson: adaptive cruise control problems

Filed May 21, 2026 · Driver assistance, Steering · PA

I am writing regarding a serious vehicle safety issue involving my 2023 Hyundai Tucson Limited purchased from on [XXX] with approximately 61,000 miles. About one month after purchase, during a drive from Pennsylvania to Florida in October 2025, the vehicle experienced multiple dangerous steering and collision-assist malfunctions in clear highway conditions. The first incident occurred in Virginia while adaptive cruise control and steering assist were active at approximately 70 mph. Within seconds, the steering wheel aggressively turned left and right, causing the vehicle to tip and nearly roll until the driver manually regained control. Later during the same trip, while making a normal lane change with the right turn signal activated, the vehicle falsely detected a collision despite no vehicle being present. The vehicle then veered left toward traffic and unexpectedly slammed on the brakes. Following these incidents, all assist sensors and automated driving features were manually disabled for safety reasons. However, the vehicle has continued intermittently triggering false collision warnings and emergency braking events with no vehicles present, creating additional near-accident situations involving surrounding traffic. I recently had the vehicle inspected by Hyundai after initially believing this may only be a calibration issue. Due to financial and scheduling limitations, I delayed service until this month, but I now understand this issue is far more serious and systemic. Two separate mechanics have advised me the vehicle has major safety-system malfunctions making it unsafe to drive. There are no reported accidents or braking issues on Carfax. I am also concerned this appears to be a widespread issue affecting this vehicle model, yet I received no notification regarding related safety concerns or recalls until conducting my own research. One mechanic stated“I’m surprised this car hasn’t killed you yet. I wouldn’t put my own kids in this vehicle." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

I was driving on a highway at 75 mph, on a clear day, with perfect visibility and driving conditions and my automatic emergency braking engaged. I was on cruise control with no one in front of me for approximately half a mile. There were cars behind me, so I had to swerve into another lane to avoid being rear ended. There was a sequence of beeps. If there were warning lights or messages, I was too busy dodging to see them. There may have been a squiggly line that came up, but I am unsure.

While driving 35mph on a 3-lane street in the far left lane, a driver of a Ford F-150 was in the center lane about two car lengths ahead, decided to make a right turn onto a residential street (as if he were driving a semi). As I got closer, the forward collision warning suddenly alerted and immediately initiated emergency braking system causing all 3 passengers to be thrown forward. I hit the steering wheel before seat belt caught me. I was not even within distance and he was turning in opposite direction of my lane. There also seems to be sensitivity issues with lane keeping feature as in Phoenix, there are never ending freeway construction with make-shift lanes not always marked well. On several occasions the steering wheel was jerked out of my hands because it couldn’t detect the lanes any longer. It has caused me to avoid freeways all together and has made me miss the exit off the freeway twice now. I thought this feature only activated during active cruise control, but apparently it does it regardless. Now I’m beginning to have problems with display going out at the worst times. I will be taking my Tucson to a dealer to have them deactivate both systems & advise of display. I shouldn’t have to pay for this. I’ll take over the driving, thank you very much!

Vehicle randomly keeps accelerating past the set speed when cruise control is set. Problem was first noticed in March. Have a video of the cruise set at 69 mph and the vehicle continued to accelerate to 87 mph before I disengaged it. Vehicle has been to two different Hyundai dealers for the issue but were unable to duplicate or find the issue. One moth ago were on a road trip and the cruise would accelerate to 8-10mph over the set speed on the cruise control especially after cresting a hill ,then the adaptive cruise control would brake hard when approaching another vehicle. 0

When the vehicle was started the SRS light remained illuminated and when driving the vehicle over 40 MPH the abs, traction control, collision avoidance, and start-stop lights on the instrument cluster come on and remained on. The adaptive cruise control, nor the button for the start-stop deactivation work. The vehicle has just over 500 miles on the vehicle and is less than a week old.
