37K miles. It started with the engine running roughly, so we replaced a coil ourselves. Seemed to fix the issue but a week later there was an intermittent noise from the engine which sounded like a very small exhaust leak (like pffffft). Occasionally, also intermittent, the engine would make a very loud clanky noise. Car shut off without warning while driving <5 mph. Our mechanic said the code was for the 2nd coil, so we replaced all 4 & spark plugs - just to be safe. Two days later, the same noise issues returned and the car shut off twice while driving in a well-trafficked downtown area (5-10 mph). It did not make noise or stall while idling. We had the car towed to the same mechanic, no codes this time. He replicated the issues by letting the car idle for an hour, then driving it 5-10 miles, it made noises and stalled while going up a very slight incline at <5 mph. He said it sounds like something to do with a loss of oil pressure sending the engine out of time, and the loud noise is the crankshaft. I don't know anything about cars and am just repeating what was told to me. At this time he drained some oil and found metal shavings. He said he could look into the problem but he would have to pull the engine and probably take it apart. He didn't want us to waste money trying to diagnose what seems to be a known issue and a blown engine. Also noted that there are few, if any replacement engines out there. In the past few months, I've had a tire sensor malfunction, the radio/media screen go blank multiple times, and the passenger seatbelt notification goes off even when it's just my cell phone and wallet on the seat. All of the electrical issues self-resolved so I didn't even have time to get too annoyed before this major engine failure. Three weeks from the first noise until this point.

Hyundai avoids taking care of their cars by sending out general statements for techs to "fix" these issues but they never do they say I didnt hear it when brought in mulitple suspension electrical issues my husbands 2019 Hyundai eletrical going out. The engine issue all they did was say didnt do it for me. They need to replace all these known issues it is braking down the whole vehichle for both of us. I believe Hyundai is negligent in worrying about the cost of afull recall so they deny anything.I have videos documents, my car went from red gas to green random clicks deterioration. My hubsands car is the only owner engine shudders randomly they do a fake iinvestigation. Hyundai does not care if you die.

- Ludlow, KY, USA

My 2017 Hyundai Elantra began to shake and refused to shift above 40mphs on a road posted 45. The engine light came on and the rmp gauge show that it was stuck at 2rmps. I slowed the vehicle and turn on my flashers and in my traveling to a safe pull off location. The engine light went off, the shaking stopped, and the car resume a normal shifting pattern. The very next day while traveling in the car the same thing occurred. I explained the problem when arrived at Hyundai and while idling and waiting to the car person to check me in. The car began to do short shudders; this was directly witnessed by a car service employee. The 2nd cylinder ignition coil was replaced. In my second visit I was sure of what the problem was because I had experienced the same car symptoms several months earlier. Here is the problem this was second cylinder I have had to have replaced in about 3000 miles and several months; my car only has 25,0000 miles. This is a known issue on the repair form it states ECU upgrade.

The car started turning off while driving the car, not making a sound. This stated when bh the car made 70,000 miles with warning, it will turn of right a stop and while driving, the problem started in June 2020, the extended warranty will not honor the claim I took my car to Hyundai after several attempts trying to find what wrong. Hyundai stated it is engine failure, and I making payments on the car.

- Lancaster, CA, USA

The car has been stalling since last February, mostly during turns, and while deaccelerating. Sometimes it idles rough and stalls at traffic lights. I took it to my dealer back then, and they told me the problem was caused by metal shavings from the engine plugging the valve that regulates fuel. I had performed regular oil changes and the dealer believed that the problem was caused by a manufacturing defect. The dealer contacted Hyundai, and Hyundai refused to remedy the defect. The problem temporarily goes away if I get an oil system flush, which I have been doing frequently. After about a month, the car begins stalling again, presumeably because the shavings are plugging the valve again. The car has become difficult to start. This morning it would not start at all.

- Ft Myers, FL, USA

The issue has happened while my vehicle has been stationary and in motion, on a ciy street, on a highway and while turning. The check engine light comes on as the car shakes. If I'm in motion, the light will stay on while my foot is on the accelerator, turn off when I take it off the accelerator and come back on when it reaches 1rpm's. if I'm stopped it will jump forward when I press the gas to accelerate (the whole time the check engine light is on). While I'm stationary, it will stay on while it's at 1rpm's or below. I have gone to the dealer a couple times already to get to the bottom of it. The first time they told me it had to do with my spark plugs so I did the service to get that taken care of. The second time I went they told me they couldn't find any code to indicate a problem. Here we are again and I'm having the same issue. This is dangerous and needs to be address as I've currently read many 2017 Hyundai Elantra owners are having the same issue. I don't see the benefit of bringing it to the dealer again if I'm just going to pay for a service that isn't going to rectify the problem and they continue to say there is no problem. I do have video to show the problem.

I purchase this vehicle in 7/2018 and had it for just over 2years and the vehicle started stalling and stopping then soon just shut down as I was driving. After getting it tow home and had a mechanic look at it. I was told the engine was bad and it was not fixable. I'm have a car I'm financing and can't use the care again. I have contact Hyundai for over a week now and no one have response. My case manager will not call me back on this. I have a case number and call everyday and all I get it rude supervisor who do not care.

Purchased a Hyundai Elantra 2017 from a dealership on July 7, 2020. The 2nd day it stalled on me feeling like it's in neutral with engine light on. I returned to the dealership and they replace the ignition coil as and said they ordered a part to return in 2 wks. This had something to do with the airbag under the passenger seat. They kept the car another 2 weeks. I was happy when they called that it was ready. Each time I had to pay the 2 tolls to go to them in jersey. Before I got on the garden state good, the car started shaking, couldn't go over 45 mph with the engine light on again. I returned it. They kept it 2 weeks. I have my car with the engine light on still and called to complain but unable to reach a manager each time. I used up over $200 of toll money which I used up plus getting someone to take me to drop off or pick up the car had to pay for gas and toll. Produced the E-zpass receipts and everything and every time I go and ask for the refund, the owner is never there. I do not want to have my new car break down with me in the middle of winter. I requested a list of the things that were done to try to resolve the engine light issue several times even from the salesman who does not take my calls or when he does, he don't know what to tell me. Said he'll ask and get back to me. No response. The first day I paid for the car and we were happy to be going home, my daughter and I noticed the front bumper all broken up and it wasn't like that when we inspected and chose it before paying. The salesman sal said there's nothing he can do about that as I already paid for the car and must accept it that way. I brought it to a saleswoman attention the last time I went to pick up my car and they only said the manager/owner will reach out to me. Never heard from them. Still didn't receive plates. I feel like they took advantage of me as a senior citizen.

Engine turned off while driving, usually after braking but also while in motion. Luckily, it was at a stop light or while I was in light traffic. It has happened on more than one occasion after driving an average of 30-40 minutes. There doesn't seem to be a pattern or a specific reasoning as to why.
