2025 Hyundai Sonata Hybrid

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.

On April 8, 2026, I returned to my brand-new 2025 Hyundai Sonata Hybrid Limited (purchased as a new ccar on February 10th 2026)_after being away from March 31 to April 6, 2026 (approximately 7 days of normal parking). The vehicle was completely dead — the 12V auxiliary battery had fully discharged. The car remained fully locked. The hood release lever and the 12V battery reset button are both located inside the cabin and were therefore inaccessible. Following the instructions in the owner’s manual, three adults attempted to remove the plastic cover over the mechanical keyhole on the driver’s door handle. None of us could pry or slide the cover off. Hyundai Roadside Assistance dispatched a locksmith. The locksmith had to use an air-inflation wedge tool to force the door open. Once inside, he pressed the interior 12V reset button and the vehicle then operated normally. This incident demonstrates a complete failure mode: the 12V system can die after only a short period of inactivity, and the mechanical emergency-access design makes it extremely difficult (or impossible for multiple people) to enter the vehicle without professional forced entry or risk of damage. The combination left me stranded with no practical way to regain access to my new car. I believe this is a safety-related defect because it creates an unreasonable risk of the driver being unable to enter or operate the vehicle after normal parking, potentially in emergency or critical situations. Hyundai has issued Service Campaign TEBA / TSB 25-01-076H for battery drain on 2025 Sonata Hybrids, but it does not address the mechanical key-cover access failure that turned the drain into a total lockout. It is also not clear the the TEBA is a complete solution to the battery drain problem.

The 12 v battery drains repeatedly causing the car to be without power . Requires opening the car with a manual key . Happens within as little of 3 days of not being driven . Dealer stated battery was without issues has continued to occur . Loses potential safety risk as entry into car becomes compromised especially if cold outside
