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.

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.

WHEN DRIVING AT NIGHT 98 % OF ONCOMING DRIVERS FLASH THEIR LIGHTS AT ME TO INDICATE THAT I HAD FORGOTTEN TO DIM MY LIGHTS WHEN IN FACT I DID NOT HAVE MY HIGH BEAMS ENGAGED. I TOOK THIS ISSUE TO THE DEALERSHIP WHICH DID IT'S BEST TO FIX THE PROBLEM BUT WAS UNABLE TO CORRECT IT. AFTER DOING SOME RESEARCH I FOUND THAT THERE WAS INDEED AN ISSUE WITH THE LED LIGHTS ON THE VEHICLE. I DISCOVERED THAT HYUNDAI ENGINEERS HAD RECONFIGURED THE PROJECTOR BEAMS TO CORRECT THE ISSUE ON ALL CARS BUILT AFTER MAY 2018. HYUNDAI WAS TOTALLY DISMISSIVE IN SPITE OF THE FOLLOWING. THE 2018 HYUNDAI KONA HAS RECEIVED THE TOP SAFETY PICK+ RATING, BUT THE RATING ONLY APPLIES TO VEHICLES BUILT AFTER MAY 2018. TO MAKE SURE THAT THE KONA'S HEADLIGHTS ARE UP TO PAR, HYUNDAI MADE CHANGES TO THE KONA'S AVAILABLE LED PROJECTOR HEADLIGHTS TO LIMIT GLARE FOR ONCOMING DRIVERS. THE LED HEADLIGHTS, WHICH ARE AVAILABLE ON THE LIMITED AND ULTIMATE TRIM LINES NOW HAVE A GOOD RATING. PRETTY MUCH IMPOSSIBLE TO SAFELY DRIVE THIS VEHICLE AT NIGHT.

I AM REQUESTING INVESTIGATION INTO EXCESS GLARE FROM LED HEADLIGHTS ON THE KONA LIMITED MODEL, YEAR 2018 FOR THOSE MANUFACTURED PRIOR TO JUNE. EXCESSIVE GLARE ORIGINATES FROM THE LED LIGHTS AND RESULTS IN CONSISTENT "BRIGHT BEAM" FLASHES FROM ON COMING DRIVERS, AS THEY THINK YOU HAVE YOUR BRIGHTS ON. THIS RESULTS IN BLINDING AND UNSAFE CONDITIONS WHEN DRIVING ON NARROW ROADS FOR BOTH DRIVERS. HYUNDAI APPEARS TO HAVE KNOWN ABOUT THE ISSUE AS THEY REDESIGNED THE LED HEADLIGHTS MID YEAR. JUNE AND LATER MODELS DO NOT HAVE EXCESS GLARE. THIS APPEARS TO BE SUPPORTED BY IIHS.ORG AT THE FOLLOWING LINK: HTTPS://WWW.IIHS.ORG/IIHS/NEWS/DESKTOPNEWS/IMPROVED-HEADLIGHTS-HELP-HYUNDAI-KONA-EARN-TOP-SAFETY-PICK-AWARD WHEN CONTACTING HYUNDAI CUSTOMER SUPPORT TO SEEK REPLACEMENT LIGHTS, THEY CLAIM TO HAVE NO KNOWLEDGE OF THE CHANGE MID YEAR AND DIRECT YOU TO THE DEALERSHIP. I HAVE CONTACTED TWO LOCAL HYUNDAI DEALERSHIPS AND NEITHER CLAIMS TO KNOW ANYTHING ABOUT MID YEAR CHANGES AND HAVE NOT YET OFFERED ANY ASSISTANCE IN ADDRESSING THE ISSUE. HYUNDAI SHOULD BE REQUESTED BY NHTSA TO CONTACT KNOWN EARLY YEAR OWNERS OF AFFECTED KONA LIMITED MODELS WITH INSTRUCTIONS ON HOW TO GET THE ISSUES ADDRESSED.

I OWN A 2018 HYUNDAI KONA SEL PURCHASED IN MARCH 2018 FROM KEARNY MESA HYUNDAI IN SAN DIEGO, CALIFORNIA. I BECAME AWARE THAT THE INITIAL KONA SE AND SEL'S SUBMITTED TO THE INSURANCE INSTITUTE OF HIGHWAY SAFETY (IIHS) FAILED FOR INSUFFICIENT HEADLIGHT ILLUMINATION. I FURTHER UNDERSTAND THAT HYUNDAI INSTITUTED CORRECTIVE ACTION AND RESUBMITTED THE KONA TO THE IIHS IN MAY 2018, WHICH PASSED AND RECEIVED A 5-STAR RATING. I CONTACTED HYUNDAI TO FIND OUT WHAT THEY DID TO CORRECT THE DEFICIENCY, AND CAN MY CAR BE FIXED. I WAS TOLD THAT THE CORRECTION WAS PROPRIETARY, AND THEY CANNOT TELL ME WHAT WAS DONE. I ASKED THEM IF THEY COULD NOTIFY POWAY HYUNDAI, SO THEY CAN CORRECT THE DEFICIENCY. THE ANSWER WAS NO. THEY ADVISED ME THAT THE BEST COURSE OF ACTION WAS TO FILE A COMPLAINT WITH THE ALTERNATIVE DISPUTE RESOLUTION DIVISION. NOT KNOWING WHO THEY ARE I ELECTED TO CONTACT YOU. HYUNDAI INTRODUCED THE CAR FOR SALE IN FEBRUARY 2018 AND MADE A MAJOR ENGINEERING CHANGE IN MAY TO CORRECT AN APPARENT SAFETY ISSUE AND THEY HAVE NOTHING TO THE CARS WHICH WERE MADE FROM FEBRUARY TO MAY2 018 TO CORRECT THE ISSUE.

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.

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 itâs 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 Hyundaiâs 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 heâs not a dealership.

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 4Ã4 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.
