Car keeps stalling no matter what speed you're driving. Took the car to NTB and they said nothing is wrong with it. It continues to happen even in busy highways where someone almost ran into the back of me. Not safe to drive. Concerned as numerous forums suggest this is a problem with 2019-2021 Hyundai Konas.

The air conditioning system has a drain for condensation. If it gets plugged up, from debris, algae, etc., it accumulates and sprays it into the passenger cabin. In my auto it sprays considerable water onto the floor boards of both the driver side and passenger side. I encountered such spraying onto my right foot making it slip off the accelerator pad while turning left. While turning right it sprays onto the passenger side. This is an actual spray of water. The dealer reports this is an owner maintenance item. This is not addressed in owner manuals. A search of google issues shows this to be a very big issue. To issues exists. Water onto the accelerator and the brake pedal are safety issues. Wet carpeting causes mold. It is a very bad design.

The horn stopped working. I have owned several cars and never had a horn malfunction. This is an important safety feature and is mandated, like airbags. They should work.

I have a 2020 Kona SE AWD and have a problem with a Check Forward Collision Sensor error that happens infrequently. When it happens, you get a ding then on the dash in a large graphic "check forward collision sensor" then BANG the brakes are applied for a split second and the car violently drops into a lower gear and revs until you turn the car off and "reset" the system. This has happened 4 times in the last 2 thousand miles. Been to the dealer twice and they cannot recreate the problem, so they can not fix anything. When this happens, its feels like a collision. It is scary and magnified at highway speed. It has happened at highway speed and low speed, both day and night.

After driving the car for several hours, I arrived at my destination and as I was parking the vehicle, it would not move when put in reverse. I received a message on the dashboard that said, “transmission problem detected.” I had the car towed the nearest Hyundai dealer. They diagnosed the issue as a transmission failure. They ordered and replaced the transmission with a rebuilt unit under warranty. I picked up the vehicle approximately 3 weeks later when the repair was completed. I drove the vehicle for 1 week before a similar problem occurred. While driving the vehicle, I received a warning message on the dashboard and the vehicle stopped on the road. The symptom of this subsequent failure was that the vehicle could not go over 2-3 mph. I had the vehicle towed to the nearest Hyundai dealer approximately 10 days ago. It is currently sitting in the dealer's lot waiting for them to "get around to check it".

My driver's side door would not unlock, either electrically, or mechanically today. I was in the car and could not exit. I'm 70 years old and a big guy. crawling over the console in a Kona to get out of the passenger side was a struggle. Took it to the dealer who said, yea, this is common. Question is, why is this not a safety recall? Had I been in an accident, the first responders would have to waste time to break open the door. If you are taking someone to an emergency room, you can't get out when you get there. This issue just randomly happened. Note the technician said this is very common, happening to all the Hyundais. He said a latch mechanism was failing. Web search shows it is not limited to the driver door.

Felt shudder and felt like transmission not catching, later a “ping” sound, then sounded like something dropped or hit (though didn’t see anything in front of me when driving) and then didn’t look behind as on interstate. Then the oil and engine lights and one other came on and the car lost power.

MY 6 MONTH OLD, HYUNDAI 2020 KONA THAT I BOUGHT IN JULY OF 2020 WITH ONLY 7000 MILES ON IT HAD ITS ENGINE FAIL AS I WAS DRIVING MULTIPLE TIMES BEFORE I WAS ABLE TO GET IT TO A MECHANIC. NO INDICATION LIGHTS CAME ON TELLING ME THAT THERE WAS SOMETHING WRONG WITH THE CAR BEFORE THE ENGINE FAILED. THE CAR IS NOW AT HYUNDAI DEALERSHIP AND THEY ARE TELLING ME THAT MY NEW CAR NEEDS A NEW ENGINE AND THEY HAVE NO IDEA WHAT STARTED IT OR IF REPLACING THE ENGINE WILL FIX IT. THIS INCIDENT HAPPENED WHILE I WAS PULLING INTO A PARKING LOT, WHILE I WAS ON THE HIGHWAY, WHILE I WAS AT A STOP LIGHT AND AGAIN PULLING INTO THE HYUNDAI DEALERSHIP. I DO NOT FEEL SAFE DRIVING THIS VEHICLE AND THE DEALERSHIP IS NOT DOING ANYTHING TO MAKE THIS RIGHT.

Mileage: 7,000
