I purchased a 2018 Hyundai Kona, and it has had one major issue after another. It burns an excessive amount of oil, the engine misfires, and now the turbocharger is failing. I’ve already spent approximately $2,300 repairing the air conditioner and engine, and I can’t afford thousands more in repairs.
The Kona barely wants to accelerate and stalls out while driving. Even though I recently got a oil change there’s oil consumption and the oil is black as if I never got a oil change. I took it to a hyundai dealer ship, i told them what was wrong they said it’s the timing belt. When that’s not the issue. I recently took it to a mechanic to get a third opinion and to see and fix what is wrong. He declined fixing it saying there’s more to it that is wrong and looks like there’s an engine defect and even complained that the oil was so black. I told him that doesn’t make sense because I’ve been getting my oil consistently. He couldn’t fix it. So now I’m stuck with a vehicle that barely drives and stalls out while I’m on the road and it keeps burning more oil. No one knows what is wrong with it.
my Kona sputters when I put it in gear EVERY TIME. I have purchased gas at several stations so getting bad gas in the tank cannot be an issue. I’ve also had to replace the coil packs twice within 6 months. December 2024 and July 2025
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.

[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
