While driving the car will stall regardless of speed or distance. Hyundai dealership states that this is due to a drop in oil pressure due to a faulty oil pump. I replaced this pump 18 months ago on 6/7/2023 with 87K miles. The car is displaying the same issue again on this date (1/14/2025) with 104K miles, and I took it to the Hyundai dealership, and they state that it is experiencing the same oil pump failure. The service department at the dealership stated that this is a known issue with these Hyundai Elantras, and this would be the third replacement of this oil pump. It was replaced once by the original owner under warranty. My contention is that this is a safety issue, because when the oil pressure dips the engine shuts off, and we lose all power to the car. This is a danger to us if this happens while driving the car.

I am writing to formally request an urgent investigation into a potential recall for my vehicle, a 2016 Hyundai Elantra GT. I purchased this vehicle in 2017 and completed my payments in March 2023. However, in late July, I experienced a catastrophic failure that has rendered my vehicle inoperable. While driving home from work, I suddenly experienced a complete loss of power. My car slowed down significantly, forcing me to pull over to the side of the road. Once I came to a stop, the engine failed to restart, despite the dashboard lights and radio functioning normally. It has now been over two months since my vehicle has been non-operational. After taking it to a certified repair shop for diagnosis, I was informed that the engine is seized. The estimated cost for repairs exceeds $13,000, which is financially unfeasible for me. This situation not only poses a significant financial burden but also raises serious safety concerns. A sudden engine seizure while driving can lead to dangerous situations, potentially endangering both the driver and other road users. Given the severity of this issue and its implications, I urge the NHTSA to investigate the possibility of a recall for engine-related issues affecting the 2016 Hyundai Elantra GT. It is crucial that affected owners receive the necessary support and that safety concerns are addressed promptly. Thank you for your immediate attention to this serious matter. I look forward to your prompt response.

I hear a lot of sounds from the engine of my 2016 Elantra that-??s only 96600 miles. It sometimes pulls back even though I step on the gas, and when the car is not moving it shakes a lot, though there is no problem according to my mechanic.

This car is consuming oil to the degree that it is empty 1,000 miles after an oil change. The engine has stalled out on the highway twice, and once on a back road. It will not accelerate properly, and won-??t go over 40 mph. I had the catalytic converter replaced less than a year ago, and I am experiencing these issues all over again.

My driver side door handle will only open from the inside and it doesn't shut inkess the door is locked and the car has to be turned on. The belt in my 2016 hyundai elanyra looks like it's shredding and it's throwing black stuff on the inside of my hood. I've had preoffwsional mechanics look at it and the alternator is assembled correctly, and now my ball joints are all of a sudden needing to be replaced inthe front.

I just know that my vehicle has a high use of engine oil. I took it to the dealer about a year and half ago to have it checked but they said that was normal but the more I read up on this it sounds like it is not normal. Also the clear over spray paint on all 4 door handles has come off and the rear hatch top window spoiler has completely peeled off also.

Bought the car a yr ago and transmission started slipping and stalling sometimes even engine shutting off while driving at higher speeds unable to steer and when pulling into traffic is on interstate almost got hit because I could not speed up it's also using double the fuel while driving longer distances I tried to use my warranty 2x before my warranty was up but both neither time did Hyundai in Owensboro check what I booked the appt for. First one was booked to check transmission and power issue then called the day before and added oil change. When I arrived the tech retyped my order and changed the oil. Brought my keys I asked about the power/transmission issues and was told they didn't know to check that but at that point there was no time and had to reschedule... So I did. Waited almost 2 months booked appt for transmission / power issue and also check the fuel usage. Finish the service call quoting me over $1300 to fix the fuel issue because no one could find my warranty eventhough I had my original paperwork showing who warranty was with and also the acct number for the warranty. When I asked about transmission or power issue I was told there was no one to check that and I had to rebook but this time it was going to be 8 weeks and by then my warranty had expired. I feel like Hyundai did this on purpose because they are in cahoots with the lot I bought the car from. Now my car is getting worse and worse and scared to even drive the car im overpaying for. This was my first Hyundai and more than likely will forever be my last because the car I got was a lemon it seems, the customer service was worthless and the service even worse. I'm reporting to BBB and everywhere I can.

Initial report on March 7, 2022 (approx. 94K miles), second report on Dec. 12, 2023 (approx. 111,700 miles). Third report March 27, 2024: Recent event occurred on March 23, 2024 (approx. 112K miles) when my vehicle suddenly stopped moving while driving 55mph on a freeway with child passenger in the vehicle, putting both of us at risk for collision. Vehicle did not have any warning lights turn on prior to or during event. The vehicle did not move again after multiple attempts to accelerate to exit freeway safely. After shifting to neutral and back to drive, the vehicle suddenly jolted and accelerated randomly while holding foot on the gas pedal (no control over timing of acceleration). We were able to exit the freeway safely. This same issue repeated multiple times while driving us to a safe area to call for a tow truck. The vehicle was towed to dealership location it was originally purchased at on March 26, 2024. Diagnostics appointment scheduled for March 28, 2024. I have completed oil change services on this car about every 1,200 miles to keep the engine running since there was no solution for any of my previous reports to dealership (even when opening a case with Hyundai), their previous determination was to close case since the diagnostics report did not show error codes in report. Previous dealership advisor made a verbal comment that the real problem is something their computers do not scan codes for, and his recommendation was to "drive it til the wheels fall off" after paying thousands in services that did not solve the root problem. Hoping this appointment will lead to a safer outcome.

What component or system failed or malfunctioned, and is it available for inspection upon request" Available for inspection upon request. Please do! Loss of power. Reported same issues a year ago. Brought to dealership, sold on other services that did not solve problem. Opened a case with Hyundai. No solution. How was your safety or the safety of others put at risk? Random loss of power. Hyundai rep stated it-??s a problem their systems do not actually scan for so it-??s common this won-??t appear in inspection reports. Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer rep drove my car and mentioned he noticed it tries to accelerate when idle, but without a code he can-??t do anything about it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A Hyundai dealership inspection was completed. Suggestion I buy a new engine. I declined since the multiple repairs paid for already were supposed to fix the problem, but they didn-??t. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No warning lights for anything in over a year but I am still dealing with same loss of power and acceleration control issues.

There are times when I turn the key and everythings turns on, lights, radio, air/heat, dash lights but the engine does not. I have been stranded multiple times and later the car will start. Replaced starter and it was not the issue. Battery tested fine.

The contact owns a 2016 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the emission valve sensor needed to be replaced. The contact's son diagnosed the vehicle and retrieved the DTC code: P0017 (Crankshaft Position). The vehicle was then taken to an independent mechanic, who replaced the emission valve sensor, variable valve timing (VVT), VVT intake, camshaft position sensor, timing chain, and camshaft sprockets; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to take the vehicle to the dealer for assistance. The failure mileage was approximately 44,000.

Component or System that Failed or Malfunctioned: Engine or other I was driving my 2016 Hyundai Elantra in Kissimmee, FL, 34746 when the engine suddenly lost power and the car stalled out. The rpms dropped to 0, and the car could not be restarted. I was able to coast to the side of the road, but I was nearly hit by oncoming traffic. After several minutes on the side of the road, I was able to restart the vehicle to arrive safely home. The vehicle also shuts off at stop lights, drive-through, or idle. How was your safety or the safety of others put at risk" The loss of power while driving could have caused a serious accident. If I had been in the middle of the road or if there had been more traffic, I could have been hit by another vehicle. Has the problem been reproduced or confirmed by a dealer or independent service center? No, I have not yet taken the car to a dealer or independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle or component has not been inspected by anyone other than myself. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No, there were no warning lamps, messages or other symptoms of the problem prior to the failure. The check engine light seems to come and go. I am requesting that the National Highway Traffic Safety Administration (NHTSA) investigate this safety problem. I am also requesting that Hyundai Motor America recall all 2016 Hyundai Elantras that may be affected by this problem. Thank you for your time and attention to this matter.
