When stopped at a light, I hit the gas and the car just sputtered. The car jolted and did not move, finally, hit the gas again it was able to move. It has happen before. My roommate's Dad told me I need to keep track of problem and file a report. I was told the injectors needed to be cleaned. I put injector cleaner into it, It seem to help but it happened again. It seems the dealer just says something needs to be cleaned.

The vehicle shut down while I was driving approximately 40 mph on a major throughway out of town. I was unfamiliar with the area and had to quickly pull over into a resident's driveway. I immediately shut the vehicle down and tried to restart it. It would not turn over, so I waited a few minutes and tried again. The engine then made a noise that almost sounded like "I quit" and would not make any noise when I turned the key after that. I called a local tow company who towed it to Firestone Complete Auto Care which was the nearest open garage. After they ran their diagnostic, they said that the engine had seized and that there was no oil in the reserve. I never had any engine lights light up on the dashboard until the second the car stopped working, when they ALL came on. My mechanic friend says that these engines have computers that time stamp when the warning lights come on, so it will be interesting to know if they use that information. I have contacted Hyundai customer service and because we are not the original owners of the vehicle, they said the powertrain/engine is not covered under the 5 year/60k mile warranty from Hyundai. We do have an extended warranty through a 3rd party company, but they are giving us a difficult time too. We are still waiting to hear if they will cover the replacement of the engine. This is a HUGE safety risk because my vehicle gave no advanced warning that it was needing service/maintenance and just stopped functioning while I was driving. If I had been on a different street or in the middle of a turn, it could have resulted in injury/death of occupants of the vehicle. My oldest son is also just starting to drive. If he were driving this vehicle when this occurred, he may not have known what to do and could have been stranded in the middle of a busy highway, where an accident could have been imminent.
The issue is when I'm decelerating to around 5 mph and go to accelerate again, there is a horrible grinding sound from the transmission and I can no longer accelerate. I then have to stop and re accelerate. This is dangerous if there is a car coming and I pull out and have to stop all of a sudden. I have 2 separate videos of…

The dealership won't fix it under warranty because they can't replicate it. The dealership won't even take a look at anything.

The Hyundai Kona was struck head-on by another vehicle. There was one driver and one minor passenger in the right rear seat in the Hyundai Kona. The driver had minor injuries while, unfortunately, the accident was fatal to the passenger. The impact of the collision caused the right rear seat to snap forward, fracturing the passenger's neck. The cause of death for the passenger was blunt force trauma caused by the neck fracture. If the seat had stayed in place during the impact, the passenger's neck would not have been fractured. The vehicle is no longer available for inspection. To our knowledge, the problem has not been reproduced or confirmed by a dealer or independent service center. The vehicle was inspected after the accident by the police. There was no symptom of the problem prior to the accident.

Letter below was sent to Hyundai corporate 7 Feb 22. They replied I should work with my Dealership to resolve the issue. Dealership cannot duplicate the fault. Vehicle has 7 speed DCT and currently has about 40k miles. "SUBJECT: 2020 Hyundai Kona DCT disengages and/or makes loud banging noise upon normal acceleration from standing stop. Occurrence is random but more prevalent in warm weather. ISSUE: While our Kona has been a mostly faithful servant over the last 17 months, including a trip from Florida to Oregon and back, it still, at random times, will violently disengage the 1st gear clutch, sometimes with a very loud 'bang.' Local Dealership mechanics cannot duplicate the fault, so what can be done? OPINION: For my wife in particular, this is a Safety Issue. When you step on the gas and the car begins moving forward but then BANG! and it coasts, bad things can happen. Like when you are trying to move out into fast moving traffic? The last time our Kona did this to me a couple weeks ago, the ‘BANG’ shook the car as violently as a collision, and I reflexively looked in the rearview mirror expecting to see an oil slick behind me. But nothing further happened and the car drove normally afterwards. Very disconcerting. NOTES: Don't get me wrong here. We like Hyundai vehicles and have owned two Sonatas, one Elantra, one Sante Fe and now, a Kona over the last 10 years. I love the' zip' from the Kona turbocharged 1.6ltr ‘mouse motor,’ the mileage is very good, and fit and finish are excellent. This is our vehicle of choice for all local trips and some longer ones." Help! Are there other owners in the same boat as I am? Is a recall pending?

In May 2023 after washing and vacuuming my car, it would not start. The battery appeared dead. I waited and tried periodically, and after about three tries, It started. This happened a couple more times, but always restarted and appeared to recharge. I did not drive the car from June - October, and asked my son to start it periodically while I was away. He tried in Mid June and battery was dead and had to be jumped. The same thing happened in Aug and Sept. Unfortunately, by the time I returned and could get in into Hyundai, it had been 38 months since my purchase. in October the battery seemed to be okay, but the horn did not work. Also, the windshield washer only trickled out and then nothing came out. I made appointment as I had also had a recall on the safety/theft issues. In November, Hyundai of Bradenton, Florida's Serviceman, Mark told me that I needed a new battery which was no longer under warranty and they replaced the horn as it was covered. He said the windshield washer unit was clogged. I chose not to pay $340 for a battery and $80 to unclog windshield washer unit from them. I just feel something is off. On my drive home, the radio came on without prompt. I turned it off, and it came back on seconds later. I turned it off again, and it stayed off. My car is immaculate, and covered when not in use. There is definitely and issue. My Kona only has 21,000 miles on it. Thank you for helping me with this. Please advise.

The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
