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)

On Feb. 10, 2026, my Sonata began showing a blue screen on the infotainment screen when the vehicle was in reverse. The blue screen contained the message "Incoming Camera Signal Error. Please try again later." Between Feb. 10 and 22, I continued seeing the aforementioned blue screen and message. In addition, I began seeing a green screen with a message "No Camera Signal Received. Please try again later.”. On Feb. 22, I was attempting to reverse from my garage and my camera failed to engage. I saw a black screen without picture when the car was first put in reverse, so I put in park and then switch back to reverse. The camera did not engage and the screen remained on the car's menu. Camera then flashed on briefly and then went back to the black screen, then moved multiple time between to the blue screen with the warning message “Incoming Camera Signal Error. Please Try Again Later.” and the green screen with message “No Camera Signal Received. Please try again later.” The issue eventually began occurring both while in reverse and in drive. During this time frame, I took the vehicle to the dealership on multiple occasions, Feb. 10 and Feb. 19, and they were unable to replicate the challenge. I took the vehicle back to the dealer on Feb. 23, and the issue was replicated. The issue was 'repaired' and picked up on Mar. 19, but had to return 3 hours later due to the same issue then in an exacerbated state. The issue was finally repaired on Apr. 1 after a complete floor assembly replacement. The issues caused the safety concern of limited visibility when driving.

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.
