2014 Hyundai Sonata: adaptive cruise control problems

Filed May 2, 2026 · MO

I was driving my vehicle on multiple occasions in which the car started to alarm and say, "Check charging system" at which point the car stopped all together. Also, when the cruise control is engaged, it will turn off automatically. It doesn't matter the speed the cruise control is set at, it will turn off.

Complete engine failure while driving. Car completely shut off and will not restart. It did not give any warnings prior to happening. Also cruise control stopped working months prior to this engine failure. Took to mechanic and he stated there is recalls on this vehicle and need to turn it in. I have also received mail stating the same about recalls.

This is a major issue thousands are having with this model 2014 sonata. When using the blinker, it causes the headlights to completely shut off while driving. Soon as the blinker turns off it kills the headlights. Extremely dangerous and hyundai seems to be ignoring this issue and pretending they're not hearing of it often. I've had to pull over many times until the lights come back on. Seems to be an issue in the steering column. Cruise control also decides when it wants to work. Sometimes on startup it works, sometimes it doesn't. I believe it has to do when the car is started. Something odd electrically with these cars. But the blinker/headlight issue is causing wrecks. This is wildly dangerous

I was just entering the city slowing from a 55 MPH zone to a 45 coming up to a traffic light when I hit the brake to release the cruise control, as I slowed down with my foot still breaking then released the brake the cruise tried to reactivate. I pressed the brake again and released and again the cruise feature tried to accelerate. I did notice that the 'set' light was off as it does when you brake but the cruise was still trying to speed up when brake released. I purchased this vehicle new, it has a little over 95k miles, but I have never had this issue before. I came to a stop at the light at which time when I released the brake it was not trying to self-activate. Especially coming into city traffic this was very concerning.

Steering wanders on a straight road. Driving in a straight line is nearly impossible. More noticeable at highway speeds, but also at city speeds, the vehicle requires constant correction to maintain a straight track. The car simply 'wanders' or 'drifts' left and right, with no real 'centered' feel to the steering. Maintaining a straight track is impossible and requires constant attention and correction. The steering wander creates hazardous driving conditions, especially on wet or icy surfaces and driver fatigue, which poses a public safety hazard. The vehicle has been brought to the hyundai dealership over 10 times for resolution, and the manufacturer has been informed twice. The dealership and manufacturer denies there is a problem and states that the individual does not know how to drive and/or that the individual would have to wait for a recall. Hyundai us has not been responsive to complaints. Cruise control has failed to operate since vehicle was purchased new. Hyundai has attempted 3 repairs and are now denying claims.
