Warnings Problems of Hyundai Sonata

Reported this previously, but more information was gathered, thanks to collision mechanic who guessed immediately when he heard 2023 hybrid Sonata - he said "they're notorious for it. " was at a stand still in a parking space/lot I know well. Cautious driver, watch my speed, very aware of other drivers, quick reaction time. Incident mid day, no pedestrians, distractions, no moving traffic. Vehicle doors shut, seat belt on. Not on incline. Pulled into parking spot I use weekly, spot has parking curb. Was at a full stop. Realized I had not pulled into the spot quite far enough, and attempted to inch vehicle forward. (do not recall any warning lights, but this car usually alerts at literally anything - even shadows. ) very lightly applied gas to inch forward, slowly. Felt slight "scrape" of undercarriage on the parking curb. Put car in reverse, lightly applied gas to inch back. Car did not rev, no screeching tires, it was at a standstill previously. Was in eco mode. All seemed normal, until vehicle suddenly launched up the parking curb, full force, and into a building pillar directly ahead. The car never moves with that much force, I'm not a pedal-to-the metal driver. Eco mode on. No airbag deployment, injuries, etc. Sheriff took report for the building, simple incident. I couldn't make sense of it. I know how overly cautious I am while parking, what I do, and don't do. Took responsibility, but was still analyzing a week later, and explained what I remembered to the mechanic. He guessed right away. Said Sonatas were notorious for it. He said they're known for randomly applying the ebrake unexpectedly - and also randomly releasing the ebrake - and aggressively (and silently) switching from electric to gas when met with resistance, aka the parking curb. Insurance totalled the car. 2. 5 years old, 17k miles. This was my 3rd Hyundai in 20 years, others were great. Discovered 40,000 elantra hybrids, same year as my Sonata, were recalled due to "unintended acceleration. ".

Car was parked, full stop, doors shut, seatbelt on. Foot on brake. Car then seemed to lurch forward by itself forward hitting parking cement block. Put in reverse to back away and car stayed still. . . Then I tapped the gas again to back up and insted vehicle plowed forward. Instead. Of reverse . . . Went over the parking block and hit concrete beam in front, when the car should have backed up in reverse. I'm a person who drives speeed limits, and ulta careful when I drive, and parked at this place/spot for years. This has never happened not sure why it did. No injuries or other people involved thank god, but scared the heck out of me. Wracking my brain, my recalls and software and service appts are up ro date. Nothing out of ordinary that day. I'm confused and shaken, why the first lurch forward and why did going in reverse move it forward? ugh. It drove home fine. Commute to work daily for years, no issues. All I can guess is gear didn't click to reverse and was somehow in drive? ive been going over the possibilities in my head for human error but they dont make sense - again I've been driving for 40 years. If it happens to other models, would love to know! car will go to repair tomorrow as "my fault" via insurance, hoping they can see more if any error codes, to at least say if reverse didn't engage or something else happened. May have been human error but it's so out of the ordinary for me. Thanks!.

On [xxx] while entering 2 car garage with no other cars in garage, the subject vehicle which is a hev, changed from the electric drive mode to gasoline mode at the garage door and driveway apex. Immediately, the vehicle uncommandedly surged forward from approximately 1mph. The vehicle impacted a large refrigerator and small table causing severe front end damage. No airbags deployed and I was not injured. Although, my neck is sore from whiplash. Seatbelts were employed and vehicle was being operated at less than 1mph, standard for entering a two car garage. There were no warnings, lights, or sounds from the multi function display or any system emergency braking applied immediately before the collision. Just a violent surge forward that I could not quickly apply the brakes to avoid this collision. It is my feeling something electronic failed to operate or was unable to understand the driving environment at the time of impact. The change in driving mode from electric to gasoline was very abrupt and instantly resulted in the surge forward with no concern for what was a potential collision hazard ahead. Severe damage was done to front end only. Resulting in a very high repair cost and may likely result in the vehicle being considered a "total loss". This is currently ongoing with insurance and collision repair facility. Unresolved currently. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

In morning dew/foggy winshield, the systems will disable easily. You get pop ups such inattentive driving disabled, camera obscured. And forward collision warning disabled, camera obscured. I’ve had many vehicles in the past and the safety systems never disable this easily over slight fog or slight morning dew. Even with a lot of fog on the winshield my other cars are still fine. I also have a 2023 elantra that has never done this before. It seems to be an issue in Hyundais new driver assistance systems in 2024+ vehicles.

The emergency rear collision detection system is able to be turned off, but automatically turns on when the car starts. There are situations where the car detects an object and it prevents me from reversing. I disabled this because I use my eyes and have accepted the risk of running into something. I had to move in a hurry two days ago, I tried to reverse out of the way, but the car prevented this when I thought I had already shut it off. Meanwhile I'm getting screamed at to move while I fumble through menus just so I can drive the car I bought. This is dangerous to have automatically on everytime the car starts.

Vehicle: 2024 Hyundai Sonata. Current mileage: 17,804 primary safety defect: electronic stability control (esc) steering malfunction the vehicle's esc system has a severe, intermittent malfunction causing unpredictable loss of steering control. This defect creates an extreme safety hazard. Occurrences include the vehicle veering unexpectedly towards highway medians and losing steering precision during turns and roundabouts, leading to multiple near-collision incidents. The vehicle is currently considered unsafe to operate. Relevant history: this esc concern was subject to a manufacturer recall. An authorized Hyundai dealership performed the "esc software logic update (24-01-065h-1)" on June 6, 2025. Despite this specific recall repair, the severe esc steering issue has persisted and recurred multiple times since that date, indicating a failure of the repair to permanently resolve the safety defect. Secondary safety defect: inaudible parking collision assistance the vehicle's parking collision assistance system is non-functional. Its audible warnings are inaudible and have never worked as designed since vehicle acquisition. This eliminates a critical safety feature intended to prevent low-speed parking collisions. Finally, the combination of a critical, recurring esc steering defect, unaddressed by a recall repair, and a continuously inaudible parking collision assistance system, renders this vehicle highly unsafe to drive. Immediate investigation and permanent resolution are required.

Whenever I am close to a Tesla in traffic or at a stoplight, my parking sensors go off. I believe that the frequency of my Sonata parking sensors is being interfered with by Tesla sensors. This could lead to unexpected braking in traffic. This problem has not been reproduced by a dealer or independent service center. It has not been inspected by the manufacturer, police, or insurance representatives. Warning sensors go off.
