Hyundai Elantra warning lights comes on

Filed Oct 7, 2026 · Engine · CA

2020 Hyundai Elantra, VIN [XXX], ~79,239 mi. On or about [XXX], while entering a parking lot at low speed on an incline, I pressed the accelerator but the car had severe power loss and then stalled. It would not move in reverse. All dashboard lights came on only after the stall. I restarted it; the lights cleared. It was towed to Westlake Hyundai, 3610 Thousand Oaks Blvd, Thousand Oaks, CA 91362; checked in Sep 29, 2026 8:59 AM. Dealer found engine oil below the low mark, no external leaks, DTCs P0302/P0304 (misfires cyl 2 & 4), and all spark plugs worn/fouled. They replaced the plugs and started an oil consumption test per TSB 23-EM-008H. Critical safety issue: the oil pressure warning light never illuminated before or during the stall, despite critically low oil. This removed my only warning to pull over safely. A sudden stall in traffic could cause a crash. The vehicle has the 2.0L Nu MPI engine covered by Recall 21V301 for defective piston oil rings causing excessive oil consumption and engine failure. My VIN is not included, but it shows the same failure. Vehicle is available for inspection. No police/insurance inspection. Manufacturer not yet inspected. Concern: engine defect and oil pressure warning system failure. Attached: Westlake Hyundai repair order/inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle stalls while driving which is very dangerous. All dashboard lights go on prior to stalling. No engine light is on. Knocking sound coming from engine. Dealer states engine needs to be replaced. Car has been serviced regularly despite that Hyundai denies engine replacement. The knocking sound that engine does is common between this model and year but mysteriously there has not been engine recalls.

Alarming rate of oil consumption causes sudden loss of power / acceleration which definitely increases probably of causing an accident. Local repair shop confirmed extremely low oil level with no evidence of where oil went shortly after oil change and annual safety inspection. All the dashboard warning lights came on when it happened but low oil warning light came on prior to event. No warning whatsoever, just sudden loss of power and completely lit up dashboard.

The contact owns a 2024 Hyundai Elantra. The contact stated that while driving 40 MPH, the tachometer, the odometer, and the power steering became inoperable, nearly causing the contact to drive off the road. Additionally, the turn signal lights were not functioning. All the warning lights were illuminated after the failure. The vehicle was taken to the local dealer, who was unable to duplicate the failure after a 100-mile test drive and returned the vehicle unrepaired. The failure persisted, requiring an AAA tow back to the dealer, who again failed to duplicate the failure during a 3-mile test drive. An independent mechanic informed the contact that the diagnostic trouble codes needed to be reset with a vehicle scanner. The vehicle was not repaired. The failure mileage was approximately 21,000.

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.

my car was going uphill and would only go about 15 up hill and would not accelerate, no lights came one to indicate any issues, then it started driving properly. Then after about 4 min it just died, in the middle of a busy intersection during rush hour. the check oil, engine and battery lights came on. Then after turning off car it came back on and all the lights disappeared but happened exact same way after 3 more min. Both times the lights went off. Now it trys to turn on but stalls right away and the check engine light is one. After taking to the dealer they stated that there was no oil in the engine. There are also no visible leaks to explain no oil. And 3 timing codes came up as a result of this. They conducted my routine oil change and still the codes came up and the car failed to start. In addition to all of this there is a knocking noise. I have an engine like those that have been recalled in the past but my particular VIN was not part of that recall. I have always done my oil changes at Hyundai dealer and on a regular schedule. This sounds to me like the same issue the other same types of engines had.

Electrical component with car has been malfunctioning. ADAS system malfunctioning (all the lights on the dash have been coming on in and out at different times) despite turning the car on and off. Video and picture evidence has been collected on different days and times this issue has been happening. Blinkers do not work when this is happening. Concerned for safety while driving. Hyundai Dealership is not helping and blowing me off.

I own a 2019 Hyundai Elantra Value Edition . 2.0L 1999CC L4. A few weeks ago we started with really cold/snowy weather and as I’m driving I’ve noticed weird knocking sound that sounds like a Ford F250 starting up. Today while stopped in traffic with the vehicle idling, the 2019 Hyundai Elantra cut off into the battery mode as if I just have my car running off of my battery (ex: roll windows up) and all of the lights on the dash board on. I put my car on the break to turn my car off and it went back into drive mode, it didn’t shut off. I tried accelerating my car went no where, within a few minutes it did it multiple times. I called the local dealer and was informed that there were no recalls associated with the VIN. I let Hyundai Webb aware of the failure. The failure mileage was approximately 197,000.

After the recall at Hyundai, my car wouldn't run and there were many lights on the dashboard. It was later checked and the instability light problem persisted. They fixed on the same time, and say something problem with the update. They later informed me that I have a problem with the brake switch, and the brake lights don't work because of it. I replaced and doesn’t work, I went back to the store and they want me to pay a fee to have it analyzed again. Even though before the recall, the lights and the car were working perfectly.
