It was able to be started two times as we tried to get out of the way of other moving vehicles but it eventually had to be towed. There were no warning lights that appeared on the vehicle to give us any indication something was wrong. It was towed to the dealership and we were told that there was engine damage, the engine needed to be replace and that it would not be covered. | Crash: No Fire: No | Unknown |

| Nov 2022 | POWER TRAIN,EXTERIOR LIGHTING,ENGINE | My daughter is in college in Tallahassee. About 4 months ago, she told me that when she presses the accelerator, the car doesn’t go as fast as it should. In July 2022, the car was serviced in Tallahassee at the dealership; however, none of this is reflected on the receipt. In November she came home to Palm Beach County, on her way back, she told me that she was having the same issue when she pressed the accelerator. She made it to Tallahassee and I had her take it to the dealership. The Service Manager called me and said she had gone over the recommended miles for an oil change and this may have caused damage to the engine; however, he decided to change her oil and spark plug which coated about $318. She drove the car for a few days and noticed a loud tapping noise; also, the car rolls in all gears, and the same issue with when pressing the accelerator. Upon taking it back to the dealer, they told me that the engine would have to be replaced at a cost of $9500. The car had sat at the dealer since November 14, 2022 because no one would call back; provide updates after I started questioning the issues with other vehicles like this one based on my research. In addition, I was told the manufacturers warranty did not apply to my daughter’s car because she was the 2nd owner. I had the car towed today, November 30, 2022 to AAMCO. It is available if needed. This issue has put my daughter at risk because Tallahassee is very hilly. The vehicle not getting enough speed to drive up a hill, pass vehicles or possibly be hit from behind puts my daughter and others at risk. The dealership has indicated there is a problem with the engine that will require it to be replaced. The vehicle was inspected by Werner Hyundai in Tallahassee who said there was an issue with the engine. It is now at AAMCO. Outside of my daughter indicating the problem, I am not aware of any other warnings. | Crash: No Fire: No | Unknown |
| Nov 2022 | ELECTRICAL SYSTEM,ENGINE | The engine suddenly started stalling at stop sign or red lights at random times and the engine immobilizer light came on along with check engine and oil light.

Other times the ESC malfunction light would show while driving and the engine would not accelerate properly on the highway and the engine would also start jerking at times. Dealer said they could not fix it as this was an intermittent issues and they could not reproduce the issue when given for repair. Dealer and company did not agree to do a complete check and replace sensors, etc. | Crash: No Fire: No | Unknown |

| Oct 2022 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING,FUEL/PROPULSION SYSTEM | Financed last year (2021) at 38,000 miles, financing a vehicle i wish I knew to do research before hestitly excepting my first offer, first waring was on the test drive. The car had to be towed back to dealership because the battery was dead. In the sub-zero cold, the battery with read low and this causes electrical issues, from remote start not working to unable to open the doors. The more common and reaccuring issue that is getting worst is the lack of excellaration when taking off. Realizing this drastic difference recently, I know there is some thing happening, but I have not had much good customer service when I have brought issues to dealership and services center. Also issues with harness for the back left lights. The harness that holds the bulb keeps burning out. Dealer has never fixed when I immediately experience this issue and they just replaced the bulb twice until they realized the real problem and told me it would cost me $160 | Crash: No Fire: No | Unknown |

| Aug 2022 | ENGINE | While driving, the acceleration stopped working and loud clanging noises were heard in the engine. There were no warning lights, nothing. I was driving on a busy road and the lack of acceleration created a major safety hazard for me and the vehicles around me. I eventually pulled over and restarted the car. It happened three more times on the way home. I got the car to my local mechanic and he said that it was the engine and it needed to be replaced. He saw this many times before on this model and told me to bring it to the dealer. I had the car towed to the Hyundai dealer/service center in Milford, Connecticut. I am waiting for them to look at it. I know that this has happened to many others with a 2018 Elantra and I am very upset that the car failed. | Crash: No Fire: No | Unknown |
| Aug 2022 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Engine stalls while driving. No warning, intermitted full shut down of the engine. Can happen multiple times in a row, only making it a few hundred feet before stalling again. The only remedy is to put the car in park and start the engine again, however, that is not always easy to do when on the road, and the car can only drift and brake. It is not safe when the car stalls, especially in traffic -- can be dangerous to myself and others on the road if I am unable to pull the car over or get it to start up again on the interstate. I have been to a mechanic, and 2 dealerships who claim they cannot replicate the problem, and even when it stalled in the parking lot when I was leaving, there were no error codes on the computer. This being said, without a code or a proper diagnosis, I am at a standstill because "nothing can be done or authorized' by Hyundai without a code. I have been suggested by both dealerships to try and run it and 'kill the engine' because it is still under warranty for another 15,000 miles--but this puts myself and other drivers at risk because the car is unsafe to drive. There is a code from July 16, 2020, a little less than 2 months before I purchased the car about an engine light, this has yet to be addressed. This problem appeared out of nowhere one day while driving on the interstate and has been an issue ever since. | Crash: No Fire: No | Unknown |

Waiting to hear what action Hyundai Corporation will take to correct issue | Crash: No Fire: No | Unknown |

| Jul 2022 | ENGINE | My husband was driving the car when all of a sudden it stalled during morning rush hour traffic. As traffic zipped by us he quickly put the car in neutral and started the car. When it turned back on the car made a loud knocking noise. He proceeded to drive back home where it stalled one more time. When he was getting close to the house the knocking noise got louder. He then called our local Hyundai dealership and they stated that they would not inspect the car for well over a week. We then had a mechanic come over the house to take a look at it. The mechanic stated that we didn’t have any oil left in the engine. Even though we had an oil change three months, the engine had burned through all of the oil. We bought oil to fill the engine but chose not to drive the car anymore out of fear for our safety and of messing up the engine any further. The car has not been inspected yet by the manufacturer, but we are speaking to Hyundai Consumer Affairs about it. Also, before the incident and at the time of, there was no lights or warnings for the engine or that it was missing oil. | Crash: No Fire: No | Unknown |

| Jul 2022 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | UNKNOWN - for the past several months, since my car hit the 70,000 mileage mark, my check engine light has come on while experiencing hard idling, delayed acceleration/power while driving - particularly on gradual inclines and hilly roads. I would suspect it has something to do with the power or fuel system. I have changed oil twice and had a diagnostic test done and mechanic is unable to pinpoint issue since it is not consistent. | Crash: No Fire: No | Unknown |
| Jun 2022 | EXTERIOR LIGHTING | Starting summer 2021, we began having an issue with the parking lights randomly coming on and off when the car is parked (engine off and car locked). The dealer could not duplicate the issue and therefore did not repair anything. The car went to college with our daughter and mostly sat parked and was rarely checked on. Now that she is home for the summer, we are again aware of the problem. The safety issue began on Saturday June 18, 2022 when the headlights spontaneously turned off while driving at night on a dark road. TWICE! I am trying to work through the local dealer to remedy the issue; however, they say there is no known issue. In the meantime, I am reporting it here. My daughter was able to get the headlights to turn back on by turning the control knob until they came on. Other details: The headlight control is always in the Auto position. The steering column has had two prior warranty repairs. The first time it was completely replaced. The second, they did some other repair that I am unsure of the details. Given the wiring goes through the steering column I can't help but wonder if it is somehow related. The dealer of course says it is not. | Crash: No Fire: No | Unknown |
