On 4/3/2023, our 2017 Hyundai Elantra was taken to Bob Howard Hyundai in Oklahoma City, Oklahoma to diagnose why it kept dying after putting gas in it. It was eventually serviced on 4/17/23 by determining they needed to replace the intake camshaft oil flow control valve, as well as a synthetic oil change, including filter and gasket-engine oil plug. Almost three months later, on 8/20/23, in Tulsa, the car just stopped running suddenly, with no active warning lights, and we found it had completely spewed out all its oil! My [XXX] son could have been killed had it happened on the highway! We had it towed to Danny's Auto Repair in Sand Springs, OK. They determined the oil drain plug had completely fallen out while driving, causing the total oil loss- and resulting in the car to come to a stop, and the engine to be ruined. They documented the undercarriage of the vehicle to show there was no other damage, and after contacting our extended warranty plan we had purchased, we were told this was not covered under the warranty. Danny's then contacted Bob Howard Hyundai in OKC, explained the issue, and Bob Howard's requested the vehicle be towed to them as they would need to see for themselves. We had it towed 108 miles back to OKC. After inspecting the vehicle, Bob Howard's contacted Danny's on 9/5/23 to inform them/us, they are NOT responsible for the engine. We sent certified letters to both Bob Howard and to Hyundai Consumer Affairs, and they opened case #[XXXXXXX]. They said Bob Howard would have to address the issue & they would follow up with them. They did, and Bob Howard again said not responsible. We reported to Better Business Bureau, and have left a message for an attorney to review the circumstances. Then today researched several Hyundai lawsuits about this same issue hundreds of other customers have had. Nothing has been done. Hyundai won't take responsibility.

My 2017 Hyundai Elantra has problems with the ignition coil packs, sensors and engine. The car stalls at lights. It idles very rough and shakes when driving. Acts as if it will stall on the highway and extremely slow acceleration. Dealer told me there was metal parts in my oil, oil was thick sludge and that I never changed the oil. False and I have the oil change receipts to prove my oil changes. I have taken the car to the dealer numerous times for the stalling and no acceleration problems. Dealer can never get the codes or replicate the issues.

I was downhill turning right. My vehicle turned off. I started it and it turned off again. Happened again. Turned it back on and was able to continue to drive. Luckily for me there was no other vehicles on the road but could have caused an accident if car was behind me. I am planning on making appointment to take to dealer. No warning signs, engine light flashed on when car turned off but that's it.

Excessive Oil consumption. My engine has stalled multiple times WHILE DRIVING. The stall typically happens while turning in the middle of an intersection. I've had several near-misses and I'm terrified of being hit. I continue to have to fill my oil in-between oil changes. This problem continues to get worse.

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)

While driving the vehicle it will start shaking. This has happened at different times and speeds so it I am unsure what the cause is. The check engine light will also come on. The shaking is very concerning and scary. The first time it happened I immediately pulled over and turned the car off. When I turned the car back on the problem was gone. When it happened again at a later date, I made an appointment to see a mechanic. The Hyundai dealership mechanic was not able to find the problem since the error code was not there when the card had been turned off and turned back on. They could not trigger the issue either. Even though they could not find the exact problem with the car they charged me over $700 to 'fix' what they *thought* was causing the problem. They said if the problem occurred again to return the car. The problem did occur again and this time I took a video of the check engine light. The check engine light and shaking stopped while driving and not me turning the car off this most recent time. I made an appointment to go back to the Hyundai dealership mechanic and they asked me "are you sure it's the check engine light that comes on." This was very frustrating, and I felt that they were gaslighting me as a female at their dealership since they could not find an issue with the car. I showed the video to the mechanic and he said, "oh yes that is the check engine light." Once again they could not figure out the issue or trigger the shaking. They said if it happens again to drive straight to the Hyundai dealership and sent me on my way.

The engine is making weird noises and the vehicle is stalling and is not accelerating. If am trying to accelerate the crank shaft noise is coming from the engine. Koi

When slowing down to turn or stop the vehicle would stutter and stall. It would not give an active code when checked, only historical for cam position sensor error. Found that it was low on oil but no signs of a leak. After an oil change and replacing the sensor the stalling seemed to improve, but it is still losing oil quickly. Purchased the car a few months ago with about 70k miles on it. After reviewing the car it seems to be a common problem, and nothing is being done to address it. Hyundai will not warranty the car since we are not the original owners, despite being within their warranty period.

Vehicles with the same year and model have been recalled due to thermostats issue. I am experiencing an issue exactly like other that have had recall have experienced. My engine overheated causing my vehicle to shut down. Smoke was coming from engine oil tank. I called Hyundai and they are advising me that my particular model has not been recalled although I'm experiencing the exact issue of what was recalled for other vehicles with the same year and model.

Car would just stall out while driving! Would have to put car in park and then try to turn back on. Also burning through oil very fast. Had to replace the timing belt just for 20K miles later having the same issue!

Had vehicle checked everything looked good, Hidden problems couldn-??t be resolved dealing with matter that could have been deadly if traffic were to occur.

Since buying my vehicle new, it has had three ignition coils fail at different times. The car begins to shudder, rough idle, not accelerate and all of a sudden just will not respond to giving it gas. This happens at any speed therefore it is a danger especially entering or exiting highways or switching lanes. It has been unpredictable. The check engine light does come on some of the time as this problem is occurring, not before. The dealer replaced the first two coils (51, 576 miles and 56, 446 miles) under the warranty. The third coil replaced (78, 391 miles), they would not cover under warranty, nor would they replace the 4th coil as a precaution.

The vehicle's engine light has been coming on for the past 3 years(2020-2023). I had multiple engine servicing checks done at the Hyundai dealership, but the dealership continued to say that there was nothing wrong with the car until this year 2023. Starting 2023 when I would drive, the engine oil light started flashing on and off and the car kept cutting off at stops AND while driving, which can cause accidents leading to death. In 2023 I started noticing that the oil kept being low, but it did not have an oil leak, it was like the oil was vanishing. Now the same Hyundia dealership claims that reason the oil light flashes on is because engine oil is going into the engine which can cause a fire to the car resulting in death. There are also a multiple lawsuits about Hyundai engines catching on fire and oil going into the engine but the dealership is claiming that it's not my particular model which I do not believe! At this point I am fearful to drive the car because it will definitely stop while in drive and stop in traffic and I'm afraid of having an accident and someone dying in the car or the car Catching Fire in my driveway or garage. PLEASE HELP these companies should not get away with this knowing MANY of there models have oil/Engine issues!!
