many times a year, without warning, vehicle dash lights turn off and light up like a christmas tree, followed by fca warning sound and lights going off, and a loud mechanical thud. Lose engine throttle going highway speeds. This can occur at nearly any speed without warning. Car must be powered off and back on to get normalcy. This puts me, everyone in the car and everyone on the highway at risk. Dealership was not able to reproduce or pull error codes.

I had the radiator replaced by the Ourisman Hyundai Laurel dealership on 10/1/25. Radiator replacement was under warranty. On 10/4/25car overheated while driving. I pulled the car over and called for a tow truck. Car was leaking lots of coolant. Brought it to service center at Ourisman Hyundai Laurel, they stated “the hose to the thermostat was not all the way on. Put hose on correctly no more leaking.” On 10/15/25 multiple lights came on the dashboard including the master warning light. Took car to Ourisman Hyundai Laurel again; received the car back, dealership stated “ TECH COULD NOT DUPLICATE THE LIGHTS POPPING ON DASHBOARD. UPON FURTHER DIAGNOSIS TECH FOUND THAT THERE WAS A CONNECTOR NOT GETTING THE PROPER CONTACT TO COIL NUMBER 1 TECH RECONNECTED THE CONNECTOR AND TEST DROVE THE VEHICLE FOR 5 MILES. NO CONCERNS PRESENT AT THIS TIME.” On 10/20 I brought the car in to Ourisman Hyundai Laurel again because Electronic Stability Control light as well as ABS warning light and several other warning lights came on multiple times. Ourisman Hyundai Laurel service technician said they could not duplicate the problem and there is nothing they can do. This is a safety issue because it concerns the electronic stability control and brakes.

While driving the car it stalled and all dash lights came in. After about 20 mins it started back up and I proceeded down the road. After a few minutes the engine light came on blinking. I got the car to a local mechanic who placed it in the diagnostic machine. It came back code engine-pistons. I have a Hyandai 2020 Kona MPI-NU 2.0l engine but it was not included in the recall of the same vehicles.

While the engine was running on the highway or also at idle, it intermittently stalled out and all of the warning lights were displayed on the dash including a collision warning. You have to put the car in park and restart it even while on the highway causing a severe safety risk. It has been to Hyundai several times for diagnostic/repair and they have been unable to identify and correct the issue. Hyundai eventually replaced the computer for lack of any other option, but the issue persists. This week the check engine light was on permanently so I took it to Christian Bros for a diagnostic and they found several codes for crankshaft and camshaft issues and determined the engine is consuming oil. OIL CONSUMPTION is a known issue at Hyundai and the subject of recalls but my particular Kona VIN number is not identified as affected even though it absolutely is having the same exact issue as described in the other Kona's recalled. I am taking it back to Hyundai this week for another try at engine 100k warranty but I know they will reject my request. How do I get this issue covered under the existing OIL CONSUMPTION RECALL for my particular VIN being that I am a 2019 2.0L engine just like all the other 2019 Kona recalls? Why is my vin excluded? THis makes no sense.

The cars battery drains to the point that it will not start or allow entry into the vehicle. This happens when vehicle is sitting and not running. All lights, screens, etc. are off when this happens also

The vehicle has started stalling about a week ago. It will just stop and all the lights go on for motor and oil and everything else. There’s a sound as well that seems to be from the engine. This is scary. It tends to be happening during slower traffic. I commute with children and this is not ok. Some of this model have been recalled for the same issue. I believe it’s irresponsible that no one has bothered to contact owners of this model. So we figure out the problem and then something is done. Not ok. It has happened at least 9 times today. I’m scared for my safety and that of my children that commute with me to the city daily on weekdays and at times weekends too.

Vehicle engine randomly stalls when slowing down, at intersections, and while driving down the road in traffic. The lives of my children and I were directly put at risk by narrowly avoiding collisions due to the engine stalling. There are multiple lights that come on when engine stalls including the check engine light, and a car with a key, as well as several others. I have contacted the manufactures due to other vehicles of the same make model and year being under a recall for the exact same issue of engine stalling. Manufacturer is failing to acknowledge that the engine stalling is a serious safety concern, as seen in the same make model and year model vehicles. Manufacturer unwilling to help reconcile issues without me paying upfront for towing, repairs, and getting my own rental/loaner vehicle. I was referred to a dealership who told me it was my responsibility to ensure that the vehicle made it to them for an inspection, no towing, no loaner or rental vehicles. I am approximately 8 hours away from home at this time and unable to drive the vehicle at this time. Reference number for call with manufacturer. Reference for call #19850095

I was driving the vehicle. All of a sudden, all the lights went out on the vehicle. This includes the instrumentation panel, interior lights, brake lights, etc. I drove the car to a safe location and stopped the engine. I then restarted the car and everything started normally.
