The car was burning through oil every 14 -21days. Car has been jerking and taking a while to accelerate. Went to machine to see what’s going he suggested I go to the dealership because there’s no leaks visible. But added more oil so I wouldn’t go without oil there was nothing available for me to come in right away and before my appointment my car started to speed up out of nowhere then completely slowed down then jerked until I could find a safe space to pull over. Check engine came on and the code was reading a misfire. Got a tune up still reading as a misfire now just stuck at the dealership playing guessing games with what’s wrong with the vehicle.

The component that failed was the connecting engine rod bearing. The engine is currently in the vehicle located at a hyundai dealership. The connecting engine rod bearing failure came after 1 or 2 engine miss-fires. The vehicle suffered poor performance, I was unable to start the car and properly accelerate the vehicle. The vehicle has exhibited poor acceleration/ jerk acceleration since purchase. However, this incident occurred immediately during initial startup in a parked position. The vehicle rode roughly upon initial observance of this engine miss fire which led us to deem the engine and car unsafe to use. The vehicle was initially towed to an independent service center where they identified the engine missfire code. The vehicle was then towed to our frequently used independent servicer where they said the problem related to low compression in the engine possibly something internal in the engine. Next we towed the vehicle to our preferred hyundai dealership. Hyundai confirmed the engine missfires and connecting rod bearing failure. A claim is in process with Hyundai to assess the vehicle further. The check engine light came on when the engine miss-fired initially. An earlier check engine light came on for a missfire earlier in the 2025 and earlier in 2022 and in 2023 which led to a catalytic converter replacement. While not certain, we think that low compression and poor engine performance has plagued the vehicle since purchase. The vehicle drive jerky(poor/delayed acceleration when pressing the gas) and had early catalytic converter issues prior to 50k miles.

The DCT(Dual Clutch Transmission) has always been an issue since I purchased the vehicle. Anytime I would be going at a slow pace in a drive-thru or traffic on the freeway the car would jolt and shake. I brought my car to a Hyundai dealership in 2021 at 36,000 miles and was told this was normal with the transmissions provided by Hyundai and there was no need to worry. Now, at 72,000 miles I was driving down CA-60 when my car transmission died. The car would not go when I was giving it gas and would make a whirring noise when trying to accelerate across the freeway until I could pull off to the shoulder. It was extremely dangerous and I could've been hit by someone especially a semi-truck as it was sudden and I was in the left hand lane. I've been bringing it to an independent mechanic for years and he always told me to wait until there's a recall as it's a faulty transmission however there has not been a recall for my car yet. The car is now in possession of a Hyundai dealership however I was told since my warranty has passed they are not claiming any responsibility but that their transmission is faulty. There was no warning lamps or messages in the car just the issue of jolting while at slow paces prior to the transmission dying.

My car started making a noise back in Dec/2024. I scheduled an appointment with Quirk Hyundai in Braintree, Ma on Dec 11, 2024, and paid for a diagnostic the service center came back that it was the oil pan leaking so on this date I had that repaired that same day total cost was $254.76. Please note that my car was under warranty at this time. On [XXX], I brought my car back to Quirk Hyundai in Braintree because the noise had returned and was intermittent, and passenger side makes loud noise when riding over bumps and the car was shaking when driving pass 65 MPH. When I had the diagnostic done on 03/29/2025 the service center came back and said it was the mismatch tires that were put on my car by an outside provider (townfair tire) and that I needed 4 new tires, oil changes, mount and balance tires and four wheel alignment which cost me $959.08. Three days later while driving home from work the noise returned and my car ept shutting off one me. I went to AXP North in Randolph MA on 04/08/2025 (had to make an appt) for a second opinion diagnostic and they told me that my car will need a new engine as the one now is failing. I called Quirk Hyundai back on 04/08/2025 and told them this and they asked to bring the car back so they can recheck my car for misdiagnosis. So, on 4/09/2025 I called Quirk Hyundai for an update the failed engine was confirmed, and now because my car is 40 miles over the warranty it cannot be fixed by Hyundai. This car is a 2018 and should last me longer than 2025. My car is only 8 years old and I have cared for the car whenever it needed maintenance. I need someone to please call me to discuss further at [XXX] . I need a new engine and Quirk Hyundai will not cover the cost despite my several attempts to have this noise resolved when care was under warranty.

The 565 and 566 required to be submitted by manufacture prior to sale in US lists the vehicle manufacturer in korea, describes vehicle as a truck and weight recorded at over 33000 lbs. The vehicle has had no safety Inspections and a rather loose self certification process allows the oversight and quality assurance that the vehicle did meet fmvss and all FMVSS requirements. Simply taking a manufactures word for it does not protect innocent consumers and endangers every driver on the road. The vehicle was driven on a fully capable scale and weighed 3, 126lbs fully loaded. The vehicle has a WMI of KM8, when a WMI search on the NHTSA website through manufacture information list only the Sonata as KM8 and decodes the vin KMH in the US not KM8. The window sticker lists a port of entry as PT, however again 0 import documentation is found. The Washington State DOL states the vehicle was manufactured in the US and shipped to the dealer. However the only US hyundai manufacture plant in the US was HMMA and they according to 555 and 566 submittal do not manufacture the Kona. The kona is not listed as manufactured by any US Hyundai rather Hatci is listed as a parent company and has a submittal of a 565 and 566 listing the Kona as a truck but was not submitted until 2023. Again my vehicle was said to have been registered in washington state in 2018. A recorded conversation I had recently with NHTSA safety hotline, NHTSA representative can be heard stating not every vehicle is tested due to lack of funding. That's not safe. I have a right to know the vehicle I am driving is fit for the road. When asked why the crash testing safecar program was created, NHTSA states to ensure safe cars for consumers when the website states it allows for incentives to be offered to manufactures to produce these safer vehicle. There is no requirments to ensure that they do. And if the car isn't randomly selected to be tested, the NHTSA does not ensure it does but takes the manufacturers word

Prt. 2continued. The TPMS sensors had been replaced, which leads me to believe that at time of tire blowout did not function Although the subwoofer was stolen from vehicle the wiring to the subwoofer was said to have caused the fire and remained intact and connected to back of the original stereo equipment. A new subwoofer was purchased and the same wiring used to plug into from before fire and the subwoofer/stereo/wiring all worked just fine. One would assume the wiring would be fried and not work properly, however it didn't at all. This lead to me investigating the vehicle on my own after not being covered under warranty and all responsibility left on me to fix the vehicle. The "2018 hyundai kona" I was sold poses numerous safety risks for every driver on the road, not just the unfortunate consumers that purchase them for the following reasons. The vehicle is affixed with a vin sticker stating the manufacturer is HMC. Hyundai motor company of Korea with a final assembly in Korea. Has a manufacture date of [XXX] and self certified by manufacturer to comply with all US fmvss and anti theft protection required at time of manufacture date. The car to date has not undergone safety crash testing performed by NHTSA. NO substantially similar vehicle is US to compare ratings to, it being 1st of its kind. The sticker also lists vehicle as passenger car, however according to manufacture rated class c and over 4,000 lbs and a Truck/SUV for classification purposes. Although sold in the US as AWD, is listed as 4×4 elsewhere. Lithium ion batteries are not standard for non hybrid or electric vehicles. No import documentation is attached to the vehicle. The hyundai kona was not placed on list of vehicle eligible to import by the NHTSA until 2020. MINE SAID TO BE REGISTERED IN WASHINGTON STATE IN 2018. The vehicles original window sticker lists part cartent as required however is not listed on the parts content list provided by the NHTSA ad required until 2020.

My vehicle suffered a tire blowout on [XXX]. It was determined to be caused by ripped beading on the inner and outer part of the tire. It was also said that the damage to the tire occurred at time of initial install by improper mounting and balancing of the wheels and tired. The tires were 235/55/r17 Kelly A/S Edge M+S tubeless radial Tires manufactured in Mexico. The tires were placed on vehicle by the dealer. My safety was put at risk because 1) the tires were not manufacture recommended OEM tires. 2) No warning indicator Illuminated on the dash to indicate the tire was losing pressure. The vehicle then a month 1/2 later caught fire. Prior to the fire several warning malfunction indicators Illuminated. In addition to what was apparent electrical haywire, causing alarm sounds ( beeping), flashing lights, and warning indicators illuminating throughout the dash. The vehicle is said to be a 2018 hyundai kona petrol. Although at time of purchase and fire was equipped with a lithium ion 20h battery. I was told an inspection was done in August of 2021 by Hyundai Motor of America after fire and being towed to the local hyundai dealer, however to date 3/2024 am still denied the report and gave never been allowed to have it. The fire said to have been caused by audio installation faulty wiring to a subwoofer secured in the back of the vehicle which coincidentally was also stolen due to the repair dealer facing to secure the vehicle during repairs. The repair facility provided a work order that only listed 2 parts replaced which were two main wiring harnesses. In addition to the wire harnesses that the repair dealer is said to have replaced, there were other documented changes and replaced parts not mentioned, listed or detailed on any repair order.

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.
