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.

Car just turned off while driving 4 times. Dealer service Said it was ignition coil they replaced. Drove it for 40 mins when I got car back from dealer (after one month) and car made a very loud noise and stopped working again. Couldn-??t get it to start and when I did it wouldn-??t go past 10 mph. Got it into a parking space and called service at dealer. Today they said they can-??t find anything wrong with it. I am afraid to drive car if this has happened on highway I would-??ve been smashed. The dealer still Has my car I want them to keep checking it out. I am afraid they will not find trouble unless they drive it for a time like I did. I contacted Hyundai corporate but they were of little help Please help

On 1/13/21, vehicle emitted a blue smoke and misfired when accelerating from complete stop from rural road onto state highway.. vehicle was taken to ciocca Hyundai of williamsport, where it had been serviced 2 days prior. They replaced 2 spark plugs and stated it was fine. Vehicle worked fine until the following morning. The vehicle was misfiring during an acceleration from complete stop and eventually quit on me. I was on a state highway at this point. The vehicle was towed to ciocca Hyundai of williamsport. They serviced it until 1/18/21. Upon pick up, they stated that they believed it to be bad fuel that was causing the trouble. The fueling station I exclusively use has no reports of bad fuel besides mine. The following morning, 1/19/21, the vehicle's main display showed an error message that "a possible condition has been detected with the engine control system. Please take vehicle to nearest dealer." See attached for image of this message. Ciocca Hyundai came and got the vehicle. They had it for two weeks. Upon receiving the vehicle back, they stated that it was just an "old code that wasn't cleared" and that the vehicle was not displaying any issues. 15 miles after leaving the dealership, that message reappeared. On 2/5/21, the vehicle felt like it was jerking slightly. I reported this to the dealer and they stated that the vehicle would be ok to operate in this condition. On 2/6/21, the vehicle emitted a blue smoke during acceleration from complete stop on side road. The vehicle then misfired to the point of almost quitting when pulling out onto a state highway from a complete stop. This could cause an accident. I reported this to the dealer who wants the vehicle to come in tonight for an appointment on 2/10/21. Hyundai Consumer Affairs has been notified of all of this but hasn't provided any course of action besides just investigation.

My husband and I were driving uneventfully down a highway for about an hour and pulled over for no other reason but to get gas. We have a high tech blue link system and only 17K miles on the car. There were no lights or warnings at all. Just after parking at the gas pump the engine started smoking and quickly burst into flames. The car filled up with smoke and we were able to get out without a scratch, but my husband had to jump back into the burning vehicle to push it away from the pump. Two fire extinguishers did nothing to stop the flames, but we were lucky that a fire engine was close by and came to finally put it out. The electric door locks had stopped working early on in this incident and they had to smash the windows to get back into the car.

Was driving Hyundai Kona down the freeway. I smelled a burning smell, I saw the check engine light blink once. The car went into limp mode and I started pulling over to the shoulder. Stopping on the shoulder, I noticed smoke coming from underneath the hood. I evacuated the car and within a few minutes, flames were present. It was between 2-3 miles start to finish.
