The cars engine vibrates when accelerating and hesitates. It is always dangerous to stall after hitting the gas. This issue causes many near accidents. It began to vibrate at less than 70k. It has 90k now. These engines have had issues and mine is no exception. They should recall this engine as it's dangerous. top of the line and poop.

Over the last 2 1/2 months the car has shut off approximately 5 times while driving, without warning. Most instances have been while pulling into a parking lot, but one time (so far) it shut off while trying to back into my driveway. I'm fearful it will happen while on the freeway. I took it to the dealer, but there wasn't a fault code so they refused to look at it unless I left the car with them to drive, and wanted to charge me $45/day for a rental so I could get back & forth to work until i

20260111LANE DEPARTURE: BLIND SPOT DETECTION

The Blind Spot Collision Warning (BSCW) light comes on 10 minutes into a drive (we live in a rural area and drive two lane roads for at least 25 miles before multiple lanes). I have had the car in for service on the system twice before learning that this is built into the system. Others are having the same problem, (see the two Hyundai Kona forum links below). I've spent about $600 trying to solve a problem Kona already knows existed (see p. 5-52 of the 2021 Kona owner's manual). Of course I

-The engine and related crankshaft components failed. The vehicle experienced complete engine shutdown while driving and later multiple no-start conditions. The vehicle has been inspected and repaired multiple times by an authorized Hyundai dealership and remains available for inspection upon request. -The engine shut down unexpectedly while driving at highway speed, resulting in loss of power and the need to coast and pull over. This created a risk of rear-end collision and loss of control in t

About 2 weeks ago I tried to start my car and the dash board starting flickering and glitch. Roadside assistance said all I needed was a battery. I got a battery and everything seemed fine until today. My car is starting to do the same thing. When I looked up recalls my VIN doesnt match for a recall I think my car should be under. The Battery Charge Sysytem is failing I believe. I have videos.

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

My car consumes a lot of oil. This is a very similar problem as the wrong tempered piston rings. All this car has used is 5W 20 full synthetic oil., which gets changed every 5000 miles. I would burn around 1 quart every 1000 miles. Dealer solution is to put in 5W 30 full synthetic oil. Got a little better but within a few months, back to burning1 quart every 1000 miles. Dealer is now saying Hyundai won’t fix the issue because car now has 116000 miles on it. This has been a problem for a while.

The piston went through the top of my engine with my entire family in the car. We managed to get to a mechanic. And bring it to the dealership. We are very lucky to be alive.

About a month after purchasing my car it shut down on the highway while driving. It completely lost power so I could not accelerate or even press the brake. Only the emergency brake stopped me from going into other cars. I started the car up again and then it worked fine until about another month later it happened again. I was on an exit ramp on the highway and it lost power. Cars had to quickly go around me as I had no control of my vehicle. Neither brakes or gas pedal worked at the time and my

I have experienced stalling on several occasions. Could I have help getting my VIN recognized so Hyundai will help me?

The HVAC drainage system in my 2021 Hyundai Kona failed due to a clogged AC drain line, which led to water leaking into the cabin and mold growth. The dealer reported the drain was blocked by a spiderweb and that moisture had collected under the driver and passenger carpets. They unclogged the line, but did not inspect beneath the carpet or inside the HVAC system. Soon after, I experienced musty odors, asthma flare-ups, and headaches while driving.
