2015 Hyundai Sonata: key fob or push-button start problems

Filed Sep 16, 2025 · CA

The car got the 993 campaign software engine immobilizer update and it was locked with the keyfob. It still got stolen. Thieves broke the lock on driver side door which deactivates the immobilizer. Car was found and police report was filed. It is available for inspection. Many Hyundais that have had the immobilizer update have since been stolen. The 993 software update is ineffective.

While driving a EPS light came in and the steering was extremely hard to drive. I was on the highway so I had to pull over to turn off the car and then turn it on. After turning it on it worked ok for a little and then messed up again and I couldn’t turning the steering wheel again. While driving in the highway my safety was at risk because I could have crashed into another car and hurt my self or other people driving. The car can be inspected at any point in time because it is at a Hyundai dealership where it got fixed a few months before. The problem was confirmed by the dealer. The vehicle has not been impounded and a selected dealer. The EPS warning light and key not detected light came on. Hyundai has multiple issues with their staring and wiring with multiple different Hyundais, including elantra and Sonata, but directly with the Hyundai Sonata hybrid. There are multiple warranties for recall 14325000. I bought this car in November 20 24 and went into the shop December 30 of 2024. It stayed in two shops, including a Hyundai dealer from December 2024 to April 2025 it had been out from April till August and went back into the shop in August. His car I believe is defective and shouldn’t be on the road whatsoever. In logically how does a whole steering column go out and need to be replaced at only 109,000 miles?!

I was driving with my 2year old grandson and my car stalled. My neighbors waving trying to alert me that my car was on fire.By the time I realized that the smoke began to come in through the vents. I had to use the key fobe to open the doors to hurry and remove my grandson from the car. The door's wouldn't open by pulling the handles. There were no warning lights or lamps messages or problems prior to the engine failure. The safety of my grandsons and my life were put to risk because of me not getting any notifications about recalls and defects.

We had a life-threatening incident when the engine remained running in our attached garage when the driver forgot to turn off the engine and went in the house with the key fob in his pocket. Eventually we smelled fumes and resolved the problem.

This hyundai sonota has a push button ignition. Once the engine is started, a person can leave the vehicle with the key fob in their pocket and the engine stays running and will not shut off. This is in violation of federal motor vehicle safety standard 114. Once the key is removed from the vehicle the engine should shut off. This engine is so quiet you cannot even hear it running while in the vehicle and if someone is partially color blind you can barely see the red and green indicator. This engine will run in an idle state no matter where the key causing risk of fire, carbon monoxide poisining and death and injury to anyone near this vehicle if left running and since the car stays running once it is started anyone can walk away with the key fob in their pocket and the car stays running no matter what. There are no reminders when exiting the vehicle that the engine is running, there is no automatic shut off in the vehicle, there are no reminders in the vehicle that the engine is running. The push button starts are not only a safety threat but also can be hazard in a parking garage if the engine catches fire due to over heating it can affect all the other vehicles in a parking garage and cause even worse damage.
