2022 Hyundai Sonata driver assistance problems

Filed Nov 6, 2026 · Driver assistance · IL

The vehicle is experiencing an immediate and severe safety hazard involving the sudden, simultaneous failure of multiple Advanced Driver Assistance Systems (ADAS). Specifically, both the front and side collision warning systems repeatedly trigger false visual and audible alerts when there are no physical obstacles, surrounding traffic, or adverse weather conditions present. Most critically, these false sensor alarms frequently result in severe "phantom braking" incidents. While traveling at normal cruising speeds, the Automatic Emergency Braking (AEB) system unexpectedly engages and aggressively applies the brakes without warning or cause. This unprovoked deceleration creates a critical hazard, drastically increasing the risk of a rear-end collision from trailing vehicles. A temporary mitigation requires manually changing the driver assistance settings from "Active Assist" to "Warning Only" every time the vehicle is turned on, as the system defaults back to active braking upon restart. Cleaning the windshield camera and the front radar plate does not resolve the issue, pointing to a deeper systemic electronic, hardware, or software network failure within the vehicle's safety management modules. The manufacturer needs to investigate this multi-zone sensor malfunction and the resulting unexpected automated braking actions.

I purchased the car new and three times since then, the latest last week, the automatic brakes kicked in briefly for no apparent reason. I feel that if a vehicle would have been directly behind me this could very well have caused an accident. Each time it happened it was during daylight and fair weather although I can't remember if the sun was shinning. After the second time it happened I reported it to the dealer and they said they had no recalls on it and no explanation but if it happened again I should record all circumstances to investigate the cause. A couple years went by and it didn't happen again until last week. Now the warranty has expired on my car. No one has inspected my car; It has driven fine except for when the automatic braking problem occurs. There were no warning or indicator lights that I noticed at the time.

The Full stereo system with cameras and most sensors and the car is currently at the dealership as 03/09 @11:00 am and I took It to them as well so that they can repair the other pending recall I have at the moment and they stated that It was a " point to point check recall " and that they would change it whether it would need to be or not and I raised concerns about another possible recall on the car and if they could check it out which is my stereo system they tried to charge me almost $200 and " the symptoms or warnings " was that sometimes it would happen but Instead of It going out completely I was able to troubleshoot it by pressing on the little button under the volume button

I have had this car for 2 years (13K miles)....intermittently the car stops short when backing up. This has happened at least 15-20 times, backing out of my garage. It also happened twice backing out of a parking space. The most recent incident was driving on the hwy at 70MPH and the emergency brake warning light came on causing the car to swerve, stop for a few seconds. Needless to say this was very scary. I am attaching a link with the same or similar complaints: [XXX] I have been in touch with Corporate. The car is currently at the dealer ship and has been for 2 weeks. They are trying to duplicate the problem, but it is so intermittent, I doubt they will find anything. I was told they have to keep it for 30 days, then....I don't know what the next step is. I love this car, but no longer feel safe in it. Please advise how you can help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I first noticed an issue with the voice resignation which also is effecting the messages navigation phone and just recently the lane assist and radar. For 2 weeks I have tried to address this with Hyundai customer service with no proper response the dealer service I stating the computer head is at fault but they have no idea when they will get one from Hyundai. I know the service people will be keeping the car for week to resolve this since the whole dashboard will be removed. I was told a representative from hyundi will be contacting me on the 5th wich I doubt will happen because when I had a problem in April 2023 I was told the same thing I had the phone nearby all day and no one ever called and I am assuming the same will happen on the 5th. This is not a dealer or service dept issue it's a hyundi problem and I am reluctant to use any of the assisted driving or rely on the safety components that this car is individually installed with.

I was driving down the street and I hit a car because I felt that I lost the control of the car momentarily and it happened as it is described on this recall - 22V746000: The vehicle's "fail-safe" limited-mobility drive mode may be impaired, when prompted by a transmission oil pump malfunction, which can result in a complete loss of drive power. As a result the car crashed into another vehicle. Have the car since 24th of March. Have been feeling at times that I fight to be the driver with the car. Spoke to friends about the issue and they were concerned about that too.

When backing up the vehicle we break when no objects are present. When stopped at a light, the vehicle will detect that cars are too close or will sense objects are around when nothing is around. The collision warning will sound at random times.

The BlueLink subscription service for my Hyundai Sonata includes a feature to see the diagnostic codes my car has or has had. Attached is a document with all of the DTCs my car has reported since I purchased it new in November of 2021. There are 15 stored codes (not active) but they are still concerning to me because they have appeared from before the car was built to about 1000 miles after I purchased it. 5 codes are for the Lane Keep Assist System, 1 for the Electronic Stability Control, 5 for Smart Cruise Control, and 4 for the Tire Pressure Monitoring System. Three of the codes occurred after I purchased the vehicle with absolutely no warning or indication of any fault regarding the LKAS system.
