Since January 2024 I have had issues with my car starting due to low oil. I just had an oil change so I knew something was wrong. The repair shop stated there were no leaks and put more oil in and said that sometimes the car will not start if there is not enough oil. February 2024 and the car wont start again. Filled it with oil and took it to the shop again. They stated that the engine is eating the oil and to take it to the dealer for a test. Since then the car has turned off multiple time both while idling and while on the freeway. When you hit the gas it will not accelerate either. In the past I was able to turn the car off and back on again and it would work just fine but now it seems more frequent. Also, while driving when experiencing these issues I have had the stereo screen shut off and restarted by itself. At times the slippery when wet alert will also show on the dashboard which has been a sign for me that they car is going to act up so I turn it off right away and back on then it runs.

Entire engine needs to be replaced due to cylinder malfunction. My safety was at risk because the car would turn off randomly at red lights or when making wide turns. Sometimes, the car would not start and sometimes it would. The problem has been confirmed by an independent service center. No messages or lights appeared indicating an engine issue.

Just to clarify, the vin number claims my vehicle is a 2017 Hyunda Elantra… but it is a 2017 Hyundai Elantra LIMITED, which there are differences in the design/model of the vehicles. The vehicle was not inspected at time of purchase like originally mentioned to me in our agreement. (They only transferred my registration to the new vehicle) I had done nothing out of the ordinary to the vehicle, after inspection the vehicle then displayed a check engine light and would not start after leaving work for the day. It then began to stall every time I applied pressure to the brake or slowed down. After inspecting the issue at Empire Hyundai they said the camshaft had been sheered by the cvvt pin and extensive repairs were needed. This happened in November 2023 and I have not been operating the vehicle since. I have gone through multiple sources to try to have this repaired by the dealership on their cost not mine due to me just purchasing the vehicle and this type of issue is a well known issue in Hyundais after they reach 100,000 miles- which I just surpassed.

Elantra was running fine, parked the car at the store and went to start it and it didn't start. Tried starting it multiple times before smoke started coming out of the engine. Had the car towed to a Hyundai dealership to have it diagnosed and found out the engine was seized and the starter was blown due to trying to start the vehicle.

The car shut out of without warning. On 10/6/2021:I pulled into the carport, as soon as I stopped the car shut off. All of the dash lights were off, radio was off, and door with not open with the buttons. The light came back on around 5 seconds later. 9/16/2021: the car shut off when was sitting in the car talking to my mom on my cell phone. Suddenly, the car shut off: no radio, no lights on the dash, the doors only opened manually. The key fob would not work. The brakes locked, the car would not start. I was able to start my ten minutes later. I purchased a battery around 3/2021.

When driving around 35 mph my vehicle had a loss of power suddenly shut off. It would not start again... I have 74k miles and the check engine light was not illuminated prior to this incident. I was merging onto a street and the loss of power had left me stranded and in danger near other cars. Vehicle was maintained well and there was no prior indications that there would be an issue. Many other 2017 Hyundai Elantra owners are having these issues and are being forced to repair their engines at a high cost.

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.

10/7/19 - my car battery was dead after sitting for 8 hours parked. There was no indication that it was losing power and I had brought my vehicle in to be serviced at a hyundai dealer a week before where they said no issues were seen with my battery at that time. I got a jump and drove home. The next morning my car would not start again. The car was towed to a shop because it couldn't even be jumped at this point. We were told by the same hyundai dealer the battery was beyond dead. And needed to be replaced. It was barely two years old at this point. But we replaced it. 7/7/20 my battery is completely dead again. Car wouldn't start again today without warning. A repair shop tested it and it was completely drained dead. They said it needs to be replaced. This is the second time in less than one year. This is not right.

In january of 2019,my car began shutting off while I was driving. The battery light would appear on the dashboard before the car would completely shut off. I tried to have it fix but nothing worked. I'm september 2019, as I was driving 60mph on the highway, I suddenly heard a loud noise after which my car shut off and would not start again. I was able to have it towed to the nearest hyundai dealership and was told I needed a new alternator, battery, and there was a misfiring. All these issues were'fixed'. My car has continued to shut off and I had to bring the car back to the dealership at which I was told they could not find anything wrong with the car. Something is seriously wrong with this vehicle and I am anxious and scared to drive this car. I have had to buy 3-5 batteries since purchasing this vehicle in 2016. My car is currently at the dealership due to this issue.
