Once again the car began to shake violently and started lunging forward while driving within city limits. Check engine warning light came on. I pulled over and shut the car off. When I restarted the car, the check engine light was no longer illuminated and the car seemed to drive somewhat normally. This was not the first time this happened, and from what I can tell by reading other similar complaints on the NHTSA website, several people are having these issues as well. It appears to be the ECM, engine control module. Hyundai needs to address this issue asap. It is very dangerous to drive this vehicle. Do not allow them to say you need new spark plugs or a software update. This is a safety issue that needs a recall immediately.

While driving, engine would turn off while driving. As I attempted to accelerate the engine would be off (no acceleration) and the engine, oil, and battery lights would come on. Dashboard electronics and radio would stay on. Put the car in park, turn it off, turn it back on - no dashboard lights on and the car now drives as normal. All instances happened while vehicle was in motion on city streets, most instanced happened while the vehicle was turning. The first time this happened I took it to Hyundai lakeland. They said it was because I had low oil (no oil indicator light had been on). "fixed" it by doing an oil change. All subsequent oil changes have been done at Hyundai lakeland. 8 months later I experienced the same problem. Car taken to Hyundai lakeland. Diagnosed as bad sensors in the engine (sending incorrect information about when the engine needs power) and a bad crankshaft (as a result of the stalling and bad sensors). Because of the multiple occasions that this has occurred and the different diagnoses that it has had from the same dealership, I am unsure if this issue has been taken care of with the last repair. An engine that turns off while the vehicle is in motion creates a dangerous situation of the driver and others as the vehicle ceases forward motion. I have been lucky that this issue has not resulted in a traffic accident.

My car had recently began to shake and buck violently while driving with no warning lights or indicators at 38,000 miles. Three weeks ago before a regular maintenance appointment at my Hyundai dealership where I bought the !car, as I turned over the ignition and accelerated the car began to buck and shake violently. As I pressed the gas, the car would not accelerate. I was in the middle of traffic in Washington, D.C. so once I was able to safely move over, I turned the car off and back over. No shaking and continued as normal. Once I took the car in the following week, I was told everything was fine and made sure to mention the shaking and bucking and was told that they didn't see anything. The next day following service and receiving my car back, my car began to shake violently again. Still no warning light indicator. I returned the car to the mechanic where my coil packs were updated (I bought my car March 2017 and was never told about any recalls on coil packs that release late 2017 until this moment). Once I received my car back I was informed that everything was okay. Well it was not. The next day I'm driving my car a short distance when two hard shakes happened. One sounded like two metal pieces colliding. I pulled over and turned the car off and back over. The malfunction indicator light is now permanently on. I had to have my car towed and now being told it could be the transmission but no updates. Seriously unsafe and could've now been in multiple accidents although I've regularly serviced at the dealership I purchased my car.

2017 Hyundai Elantra used ran great for a while, the one of the four coils went bad, started to shake and the dealer replaced the coil, and ran great, and now the car started shaking again and check engine light came on and I set an appointment for the dealer the day I take to the dealer the check engine light went out and it was running great, so I took it to the dealer anyway and they told me it was the coil, and it wasn't covered under warranty anymore, but the car was running great, so I've been driving it, and now every now and then it shakes the check engine light comes on and when I step on the gas the check engine light goes out and the car runs great. There should be a recall!

I bought my 2017 Hyundai Elantra used 6 months ago. 4 months after I had it the car was shaking violently and did not want to accelerate. Took it to a mechanic he said it was misfiring and replaced ignition coil. It was driving fine for 2 months then while driving to work on a major highway the car started shaking violently again and would not accelerate to speed it was shutting down.. had to have it towed. Mechanic ran a diagnostic on it and its reading multiple misfires. I can not afford car payment plus having constant repairs done every couple months.. there have been so many of the same complaints on a 2017 Hyundai Elantra engine problems. This is obviously a real concern for a newer car. Hyundai needs to fix the issue for this year and model. Or there needs to be a lawsuit against Hyundai... these are lemon cars and are unsafe to drive they need to be held responsible for it.

My car is continuously getting check engine light on and the car rattles. Despite, visiting the dealership numerous times, the service center at the Hyundai dealership in dickson city, pa cannot solve the problem. 12/10/2019 - my car started to shake and the check engine light came on when I was leaving for work. I pulled over and turned off the car. I turned it on, the light was gone. I took it the dealership on very same day and the service advisor said nothing is wrong with it. Additional services; oil change, brake flush and cooling system were completed. 12/31/2019 ' check engine light came on and car rattles when I was driving on interstate highway doing around 55-60 miles per hour. 01/02/2020 - I took it to the dealership. This time, the service adviser said "a lot of Elantras are experiencing this issue and needs software update". they scanned and found code P030100 / misfire. Technician performed software update and all the cost was covered under engine warranty. 01/27/2020 ' check engine light came on and the car started shaking again. This time, the check engine light stayed on. They finally replaced spark-plugs and coil pack on cylinder 2. 03/20/2020 ' due to coronavirus pandemic, I've been working remotely so I haven't driven much. 04/18/2020 ' completed state inspection and emission. Service center performed multi-point inspection and found nothing wrong with the engine. 07/15/2020 - the car stalls again, the check engine light comes on and off. I stopped driving it and dropped it off at the dealership on 07/17/2020. 07/18/2020 - technician did a new software patch for the second time. Additional services: Oil change, battery and front brakes replacement completed. I think this need to be investigated and deserve a full recall for all the 2017 Hyundai Elantra who are experiencing engine issues.

The engine started rough idling periodically (once per week) at the beginning of this year (2020). Restarting the car would usually resolve the problem. It would usually happen after coming to a stop after highway driving. However it began happening with more frequency in April to the point that it could happen multiple times per day. The issue came to the head the first week of may when the car stalled after coming to a stop at a street light. This time it was after only minimal city-street driving. I had to shift into park and start the car again, after which it worked without issue. However the check engine light was on. I took the car to my mechanic same day and they said the code indicated a misfire. They replaced the spark plugs and the ignition coil for the cylinder that misfired. The frequency of the issue decreased significantly after this repair, but it's still rough idling about once per week. I decided to research the problem before having more work done and have found many similar complaints. The car has 41000 mile on it.

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.

I bought a 2017 Hyundai Elantra limited edition at the end of 2016 it had 43 miles on it. I have taking it to about 6 different dealerships due to transmission issues and engine power loss and out if the 6 I have gone more the a few times. Their response to my concerns about the car is we cannot reproduce this so there is no problem or there's not a check engine light on. Every dealership that I have gone to repeat this saying over and over. When my car shifts into second gear it's almost as if that gear has two more like driving a stick shift but you're shifting too soon so it spits and sputters, in addition to this 3rd 4th 5th gear has a long delay in shifting it also feels like the transmission is slipping as the rpms and speed come up it feels like the transmission grips and you can feel the torque kick in if you will. There's been many times I have to manually shift the car out of 5th into 6th and a few times out of 4th. My car has 38970 miles on it. I had the transmission flush and the engine, ignition coils have been replaced, I use premium gas and fuel injections clearer. Nowadays when I'm driving I have to push the gas pedal halfway down for the car to actually move. This has been going on about six months after I got this card.
