What 72 owners told NHTSA about the 2018 Hyundai Kona

Vehicle was traveling down the highway with cruise control on and suddenly proceeded to not maintain speed and lost the ability to accelerate and shake in the middle of the interstate. Check engine light came on after this and we were able to limp it off the highway onto the ramp. No warning lights, no over heating, or any signs were given prior to this incident to give the impression this vehicle would stop operating. My family's safety was put at risk as it lost speed suddenly on the interstate in the middle of traffic and could have caused other cars to hit us as we slowed and tried to get over to access the ramp. Vehicle was towed and inspected at a local mechanic and was informed there was oil burned on the spark plugs and cylinder 1 and 3 had little to no compression.

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. The original lithium ion battery had been replaced. Two- 50v main relay fuses in the relay box located in the engine compartment had been replaced. Prior to fire read HMML, after repairs read PBD01.

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.

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

I have a 2018 Hyundai Kona, with approximately 42,000 miles on it. The right front passenger door began having problems sometime in 2022. When I first inquired about the door at Riverside Hyundai, I was advised that the problem might be covered under warranty. I did not have the problem diagnosed at that time. Today, I had the problem diagnosed, and I was advised that the repair would cost $453.00, with parts and labor. After Googling the problem, I discovered that quite a few Hyundai owners have a problem with their door locks. I wanted to report the problem since it seems ongoing, and Hyundai has not provided a satisfactory resolution.

UNKNOWN. AC stopped working. According to repair shop, alternator belt sliced through the aluminum housing tube and Freon cannot be recharged . It needs total rebuild/reroute of AC tubing as The position and location of alternator belt is too close to the aluminum housing/tubing for cooling system. This is a bad build/design. When it’s really hot outside this is very dangerous for all passengers in this vehicle. Repairman/mechanic said he has seen this issue more and more on several Hyundai’s that came thru his shop, that he believes a common defect and has educated him as first thing to look for on a Hyundai needing AC repair.. and one can speculate there are MANY more, since he’s not a dealership.

My vehicle suffered an electrical fire that wasn't covered under warranty just 2 months after I purchased it. It was inspected by the manufacturer, repair facility(licensed dealer) and insurance however I was denied the inspection report. A Hyundai warranty information sheet states my vehicle had 1 unrepaired service campaign in 6/2022 for the FCA forward collision avoidance. Which meant it was also sold to me without being disclosed. However the NHTSA website says it has 0 unrepaired recalls. Right before the electrical fire the electrical system went haywire. My safetey and my childs safety is at risk everyday I have this vehicle. Without my knowledge or consent, the dealer and my insurer choose to authorize repairs. The fact that at the time of purchase, no safety or crash testing had been completed by the NHTSA is concerning. All vehicles without NHTSA safety testing completed, prior to the 1st being sold and driven on the road puts everyone at risk. The fact that NHTSA does not require these safety tests to be conducted on every single vehicle driven in the states puts everyone at risk, not just my family. Even worse after my vehicle caught fire and caused $12,000 in damages, my car has a clean carfax. There is nothing making reporting this mandatory. insurance companies, thhe dealer/repair facilities do not have to report to the DOL or anyone for that matter that the car was involved in a fire at all. In fact the repair/dealer my vehicle went to reported it as multipoint inspection, maintainence. This puts all drivers and passengers at risk on the road. There's no question that a vehicle after having caught fire and suffered electrical problems is no doubt more susceptible to additional problems down the road. This puts all cars and people on the road in danger, not just me and my own.

Oil change was on 1/13/2023 at 33,505 miles. On 2/25/2023 at 35,366 miles after driving on the highway for about 30 mins at 65 mph, the oil light came on and car was making a loud noise as I pulled in to park. My car was parked for about 1.5hrs at my destination. I attempted to drive home and get back on the highway when my engine stalled at about 40 mph and my engine and battery light came on. I had to pull over to the shoulder as my car would not drive anymore. My car was then towed to my house and later to the hyundai dealer where they determined that my engine stalled due to lack of oil because my drain plug was missing. Hyundai refuses to fix this under warranty because the drain plug is missing and they are insisting this is because of the oil change place I went to nearly 2 months ago. When I went to the oil change place, they insist that they didn't do anything wrong, and if they did incorrectly put the drain plug on, my oil would've leaked much sooner than it did. There is currently and investigation with NHTSA with my exact issue where the oil drain plug still falls out, even if the person performing the oil change puts the drain plug on exactly how it should be. Directly from the NHTSA site: "Apparently, the thin metal, along with engine vibrations and expansion/contraction tend to loosen the drain plug without any other intervention. NHTSA is investigating this as a factory defect issue." My safety was deeply put at risk as I was driving on the highway when this happened and I could've easily gotten into an accident and faced injuries. I'm stuck in the middle as the oil change place denies it is their fault and hyundai refuses to fix under warranty strictly because the oil drain plug is missing. When I explained to them that I would've have this issue with my engine if the drain plug was present, they agreed. They are stating that it is $10,000 to repair my car and that I have to pay upfront and cannot do multiple payments

We had parked our 17 year old son's car in the upper parking lot of our baseball field. While parked, the engine smoked, then spontaneously caught fire. The police arrived on sceere!!!! We totally cannot comprehend that this even happene, along with our fire department who was able to put out the pretty massive engine fire, along with some of the front being damaged as well. Our son had been driving this car to our high school and also the high school baseball field, with pretty packed lots. It unbelievable to even imagine if this happened thned to a pretty new car (22,000 miles on it). We are so very grateful that this did not happen while our 17 year old was in the car! This is truly needs to be looked into. Thank you.

Vehicle engine randomly stalls when slowing down, at intersections, and while driving down the road in traffic. The lives of my children and I were directly put at risk by narrowly avoiding collisions due to the engine stalling. There are multiple lights that come on when engine stalls including the check engine light, and a car with a key, as well as several others. I have contacted the manufactures due to other vehicles of the same make model and year being under a recall for the exact same issue of engine stalling. Manufacturer is failing to acknowledge that the engine stalling is a serious safety concern, as seen in the same make model and year model vehicles. Manufacturer unwilling to help reconcile issues without me paying upfront for towing, repairs, and getting my own rental/loaner vehicle. I was referred to a dealership who told me it was my responsibility to ensure that the vehicle made it to them for an inspection, no towing, no loaner or rental vehicles. I am approximately 8 hours away from home at this time and unable to drive the vehicle at this time. Reference number for call with manufacturer. Reference for call #19850095
