2017 Hyundai Elantra: multiple warning lights

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.

When coming to a stop, turn or sometimes when driving throttle goes to zero, oil, engine, and battery light come on and gas peddle no longer works (car no longer accelerates) . Have to turn car all the way off and restart it and it runs fine (all lights turn off and car accelerates) until coming to a stop again (the same exact thing happens). Went to trade it in as soon as person test drove it he almost crashed because the engine stalled again. This has been happening for months but progressively worsened (happens very often now almost causing crashes)

The engine stalled out while driving on the highway. No indicator warning lights came on. The vehicle would not restart. Had to be pushed off the road. Prior to the engine, the tire pressure gauge warning indicator light did not work when tire went flat. I was driving on the interstate 23 back end slid. I pulled off the road and the driver side back tire was completely flat. Put on spare tire.all the lights on dash came on . Went straight to tire garage had 2 tires on back put on.

While driving on the highway a loud noise was heard like metal falling all the lights on the dash board lit up, the car started slowing down and started to smoke then turned off. Had it towed to a service station and was told that the piston from the engine shot threw the oil pan causing the engine oil to pour out and the causing the engine to seize.

While driving in the expressway or road the car will suddenly shut off. All of the lights will come on in the dashboard and I have to put the car in neutral or park to start it back up. It will also shut off if I'm turning slowly around a corner or if I come to a complete stop after driving for awhile.

Several times while driving in the dark when switching from low to high beams or high to low beams, all lights go off causing a very bad safety issue! They come back on after several seconds.

While the car was sitting in the drive, the car was turned off all of the lights except the headlights and reverse lights turned on. The only way I could turn them off is if I turned the car on and back off. It has happened 3 times in the last 3 days. The first two times it happened was about 2 hours apart from each other. The second time the lights turned off on their own within 30 minutes. The third time I was at work and am not sure how long the lights were on but I walked out of work to them on.

While driving the car it suddenly stalled rendering the brakes and steering useless. Managed to coast to the side of the road and stop. Placed the car in park and attempted to restart the car. Most if not all of the dashboard lights came on but no engine sounds. Also the car was now stuck in park. A tow service was called and the car was towed to the dealer where it has sat since december 28, 2016 because they are unable to diagnose the problem.
