2025 Hyundai Sonata Hybrid problems

ELECTRICAL SYSTEM

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.

ELECTRICAL SYSTEM

The horn stopped working unexpectedly. Pressing the horn button produces no sound. The vehicle has not been in any accident. This is a safety issue as the horn is required for alerting other drivers in emergency situations.

STRUCTURE:BODY

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.

UNKNOWN OR OTHER

The Inattentive Driving Warning goes off excessively, causing distraction even in heavy traffic. Over a 2 hour drive, the Inattentive Driving Warning would alert approximately every 30 minutes regardless of traffic or driving conditions. The sound, which lasted approximately 1 to 2 seconds, and alert display caused me to momentarily turn my attention to the instrument cluster, rather than the road, while I was traveling at highway speeds in variable traffic. Previous model years allowed you to turn off this function, but this is no longer the case. Hyundai even confesses the inaccuracy of the system within the manual and has sent out notice of ways to lower incidences on different models vehicles.

LANE DEPARTURE: ASSIST

The dash warning "Consider Taking A Break" fires off randomly. This is a distraction as when I'm in traffic, driving well within my lane, no sudden changes, it will alert and I look down as I assume there may be a more serious problem. It takes my attention from the road often. This feature cannot be disabled. I've contacted the manufacturer and the local dealership. The local dealership suggested that there is a way to do it but they cannot tell me as it could be a liability. I don't see how it would be a liability as it is me doing the disabling. If anything that could be corrected with a statement I'd need to click stating I know the added risk of disabling this or something. It's annoying and at worst, may cause an accident as it pulls the driver's attention from the road. I'm hesitant to let anyone else drive the vehicle as they may be less prepared for the warning and may cause confusion as they try to determine what it is.

VEHICLE SPEED CONTROL

The gear shifter design on this Hyundai model is dangerously counterintuitive compared to industry norms. It nearly caused me to drive off a cliff. I encountered a serious safety issue with the gear selector design. In most vehicles — including Mercedes, GM, and even pickup trucks — pushing the gear selector down engages forward drive, and up engages reverse or park. Hyundai has reversed this logic. In a rushed moment, I instinctively pushed the shifter down expecting to go forward (as in most cars), but the Hyundai was in reverse. I stepped on the gas and nearly backed off a cliff. This design is not just unfamiliar — it's opposite of established standards. Drivers with muscle memory from other vehicles like ANY pickup truck, MB, or GM EV are at real risk of making fatal errors. I strongly urge NHTSA to investigate whether this shifter design meets safety and human factors standards. At a minimum, Hyundai should issue a UI/UX recall to standardize shift direction or implement safeguards to prevent this kind of mistake.
