2017 Hyundai Elantra: key fob or push-button start problems

Filed Apr 22, 2026 · Acceleration, Electrical · CO

I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving. This most often occurs when I am decelerating and turning, such as when entering or navigating roundabouts. At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the failure occurs—no unusual noises, no loss of power leading up to the event, and no dashboard warnings in advance. The stall is sudden and unexpected. When the vehicle stalls, I must quickly shift into park and restart the engine. The car restarts immediately without hesitation, and all warning lights disappear. The vehicle then operates normally again until the issue randomly reoccurs. This has happened multiple times. This issue creates a safety risk because the vehicle loses power unexpectedly while in motion, particularly during low-speed turns and in roundabouts, which could increase the risk of a collision due to sudden loss of propulsion and reduced control. The problem has not yet been formally diagnosed by a dealer or independent repair shop, but based on research and similar reported cases, it may be related to an intermittent engine or electrical signal failure. The issue has not yet been inspected by the manufacturer, police, or insurance representatives. UNKNOWN as to the exact failed component, but the failure appears to involve a sudden loss of engine operation without warning, followed by immediate recovery upon restart.

For a little over a year now, my back doors do not open on my Hyundai Elantra. The child lock is not on. Also in the past year, my passenger and driver door do not open. I have to go back and forth on the handle 20-30 times before my door opens. I have changed the battery in the key fob and I have tried unlocking my doors with the actual key with no success. Sometimes if they do not open I have to go through my sunroof. This is such a safety issue it’s insane. I’ve called Hyundai dealerships but they said they will need to keep it for 2 weeks. I do not have any other vehicle to just leave it there for that long. Please help.

The door opening mechanism in both the drivers door and the right rear passenger door continually does not allow the door to open resulting in the driver and passenger becoming trapped in the vehicle, and often does not allow opening of the door to enter the vehicle. I and my passengers have been trapped within the vehicke several times where we unsuccessfully tried to use the cars unlock button, the key fob, the key, and even the manual lock levers in conjunction with either the inside or outside door levers. It is dangerous to be trapped inside a vehicle and so i believe this issue should be corrected by a manufacturers recall

I attempted to open my rear passenger driver side door and it wouldn't open from the outside, then tried inside door handle and still would not open. Tried the door lock and key fob. Still would not open. Searched on Google and many other people have the same issue with the same car where the rear driver side door will not open. This is a safety hazard as you are unable to escape from the vehicle in an accident from that door.

I'm having constant issues with my front doors. Last year There was a door latch recall issued for the front drivers side door. I took my car to the dealership to get it handled however my FT DS door was making a clicking sound. It was fixed but since gone back to the dealership twice and now possibly a third time due to FT PGR Door making the same noise.. I keep getting locked out of my car or the doors wont close right. All doors make a clicking sound when opened. Which is one of the reasons I have taken car twice. The main concern is me not being able to get in the car without having to click on the key fob and doorlatch getting stuck.

I just bought my car used on May 10, 2022. I have been unable to open my driver side door and having difficulty opening my passenger front door. I had the battery on the Key Fob replaced but It is getting more and more difficult. I have to climb into the passenger side to get into my car or have someone open the door manually from the inside of the vehicle.

The car shut out of without warning. On 10/6/2021:I pulled into the carport, as soon as I stopped the car shut off. All of the dash lights were off, radio was off, and door with not open with the buttons. The light came back on around 5 seconds later. 9/16/2021: the car shut off when was sitting in the car talking to my mom on my cell phone. Suddenly, the car shut off: no radio, no lights on the dash, the doors only opened manually. The key fob would not work. The brakes locked, the car would not start. I was able to start my ten minutes later. I purchased a battery around 3/2021.

The door locks on my Hyundai are not working properly. They do not open from the outside or inside, even though the lock buttons are operational and the key fob is working properly. It is a safety risk that they do not open properly in case of an accident or fire. I've read websites on several internet boards that this is a recurring issue with Hyundai vehicles and this poses a very big risk for owners. The body shop technician I took the vehicle to shared the same concerns about the faulty issues from Hyundai and is still working to resolve the issue part by part. The little CLS stopped working almost suddenly, with them opening from the outside after several attempts, to then not opening at all from the outside, to then not opening from the inside or outside. There is no open recall for this issue even though several individuals have reported and is a known defect.

Driver side door periodically will not open from the inside or out. Just started happening about 2 weeks ago. Thought it was my key fob dying however I replaced the battery and it still is causing the same issue.
