I’ve been having issues that align with the Safety Recall 239 to repair a condition involving the Electric Power Control Unit ("EPCU"). I seem to be having by a coolant leak, my car is overheating, has stalled and has struggled to start. I started noticing something wasn’t right a couple of weeks ago but wasn’t sure what until more “symptoms” have occurred since and I found the recall information. My air conditioner also will stop blowing cool air when the over heating happens. No lights have come on my dash board alerting me of anything needing to be serviced.

The shark fin antenna came off at 55 mph going down the highway. The dealer who sold me the 2021 Kona SEL, tried to blame us for it, saying there is no way to know if you hit a bird etc. They stated it would cost me about $1,300.00 to repair this. My response was, are you serious? we have had this car for less than 3 months and this is your answer. So i went to a certified Hyundai dealer, both gave the same response, but added our tech is trained to spot defects and said the screws would not be shown, it would have ripped the entire unit from the car if it came off due to a defect. which is entirely untrue. Both dealers added that they had never even heard of this happening before, so they referred me to contact Hyundai corp to open up a registered complaint. The response I got was the dealer was the one who makes the ultimate decision. she gave me a link to buy direct from Hyundai as soon as I stated I would make a complaint here. Then I asked her the same thing I asked both dealers, why are you denying this? This is a very common issue. I also added that if the truck behind us was struck by the antenna ripping off, I would be in court to sue them. I then added it will only be a matter of time before injuries or death from this occurs and that will end up with all of the complaints being used in court to force you to comply. I ended up finding a better deal from a Hyundai dealer than the one she gave me. I performed the repair myself. the repair cost me about 300 dollars. I also want to ad that when i used AI to ask how to tell if the antenna was defective, the explanation and pics were exactly identical to the pictures I took. as this was during warmer months I felt very happy a person on a motorcycle was not hit. People need to research this on their own before purchasing this auto in my opinion.

Antenna is poorly designed and falls off. A quick internet search shows this is a common problem across thousands of Hyundais and Kias (same company). Because drivers are more and more dependent on GPS and radio based emergency notification AND vehicles more and more depend on interactive troubleshooting and reporting this is a safety issue. The manufacturer is aware of it, and it should at the very least be covered under warranty. Because it is a wide spread problem that many dealers appear to be refusing to repair even under warranty it should be a recall issue. My local dealer denied it was a warranty issue, but I have appealed their decision with Hyundai. It should be a safety recall issue.

The horn stopped working shortly after purchasing the vehicle in July 2021. We have been waiting for an appointment to get it looked at for months with our local Hyundai dealer but they don't have any service appointments. There have been several close calls with other vehicles and pedestrians and it is only a matter of time before something happens.

I'm trying to find out when my 2021 KONA SEl PLUS was built and where ? When did the maker of the oil rings notify Hyundai of the defect to the rings why was Hyundai able to sell of these Kona's with the 2.0 engines from dealers lots after they knew there was a problem with the engines. My Kona was sold to me on 25 Feb. 2021 they had to know of the problem by than. I was so angry and upset with my dealer when I check with them about the recall and THEY TOLD ME to DRIVE IT TILL IT BLEW UP OR CATCHES FIRE and have it Towed IN. I sold it back to them and loss 3,000 dollars rather than drive it another mile.

Having acceleration problems. 1. While driving in normal mode, when accelerating from 55 to pass cars on the highway, the tach moves to higher levels but the car doesn't accelerate. I need to take my foot off the Gas Pedal and wait then try to accelerate again. 2. When a stop light, at a full stop (or stop sign) - the car bucks before accelerating. 3. when I start my car from a cold start and in idle mode - still in park - the tach hops for 30 seconds before settling. All these issues do not happen all the time. Hard to replicate.

I had a flat tire (passenger side right front tire). Triple AAA removed tire and replaced with my spare tire. While driving to the Hyundai dealership, massive clouds of smoke poured out of my exhaust pipe in rear of car. I also had trouble steering the car. The result of using the spare tire burned the transmission fluid (also contained metal shavings). The transmission had to be replaced along with the fluids in my car.
