| Electrical System problems |
The vehicle is stalling in the acceleration process. I can feel and hear the stall by the air conditioner going out or fading out when it happens while driving. Pressing the gas and it barely moves at times. Makes a noise now while running. Unknown to whether it's electrical or engine or transmission. Pull out in the traffic accelerating but the car wasn't moving at the pace it should have. Could have cause an accident when trying to cross on going traffic. Just got the vehicle 2 weeks ago. No one has inspected the vehicle yet. Going to have it looked at for recalls. No warning lights appeared to reflect an issue, but there clearly is.
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 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.
