2020 HYUNDAI KONA Complaints

I am the original owner of a 2020 Hyundai Kona equipped with the 2.0L Nu MPI engine. This engine has been subject to known manufacturing defects, including excessive oil consumption, timing component wear, and premature failure. Hyundai has acknowledged that my specific engine falls within the range of engines affected by this defect and has confirmed that it is part of a recall/service campaign group. However, Hyundai is refusing to repair or replace the engine because it passed a vibration test back in 2021. That test was performed over three years ago, and my vehicle is now experiencing major engine problems, including the activation of check engine light with code P0017, which refers to crankshaft-camshaft correlation issues — a known symptom of the engine defect. Hyundai is denying coverage based on a test that is now outdated and irrelevant, despite the fact that the engine is part of the known defect group and is showing signs of failure consistent with hundreds of similar cases. The vehicle is no longer under powertrain warranty, but the root cause of the failure is clearly related to the previously identified defect. Hyundai’s refusal to act puts me, and potentially others, at risk of sudden engine failure due to timing or lubrication problems. This is a potential safety issue if the engine stalls while driving. I respectfully request that NHTSA investigate Hyundai’s use of past vibration tests to deny coverage for active and dangerous engine defects. Owners like myself should not be penalized for a test performed years ago when clear evidence of failure now exists.

While driving on the highway, our vehicle suddenly stopped accelerating without warning, forcing us to pull over immediately. There were no warning lamps, messages, or prior symptoms before the failure occurred. We had to stop on a narrow shoulder with no guardrails, leaving us exposed to fast-moving traffic and putting our safety at serious risk. The vehicle was inspected by a local dealership, who diagnosed the issue as a failed fuel injector. This component is available for inspection upon request. The problem has not been reproduced, but the diagnosis has been confirmed by the dealer.

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 was driving when I heard a rattle below the car. About a mile later, my engine died. Turns out the oil plug fell out causing irreparable damage to my engine. Was fortunate to be able to coast down the bottom side of the bridge I was on to a safe spot off to the side.

Car is losing power. Car is stopping in the middle of the road. Car was towed to my Personal mechanic on June 21,2025 who has ran a diagnostic on vehicle & vehicle is throwing out an Engine Failure Code. Check Engine light is blinking ; car is making odd "knocking type" noises. First appeared June 20, 2025. Car is not safe to drive due to losing power. Vehicle is now being towed to the dealership (after multiple calls) and the loss of power is concerning/dangerous if vehicle looses power with traffic around. I feel I won't be able to get the vehicle and myself off the road safely before an accident/injury/fatality occurs. I will upload a copy of the diagnostic report

My wife was pulling into a parking place at Home Depot when the car suddenly accelerated, jumped the curb & hit a tree on the sidewalk. It did significant damage to the front bumper of the car but the airbags did not deploy & my wife was not hurt. I am guessing that it will be several thousand dollars to repair.

On 3.22.2025 the rear view camera did not display; either a black screen with text "Check surroundings for your safety," a green screen reading "No camera signa received. Please try again later," or distorted images appeared. Camera was replaced under warranty on 4.14.2025; I learned from Crossroads Hyundai that other vehicles had a recall in effect. Images and work order are included.

Recall 203 was done on vehicle immediately upon purchase in 2021. Recall 974 was done and CNDS software installed in 2022. Engine stalled and check engine light came on at the end of February. Took car in March 11th to the dealership was told that the engine would need to be replaced due to code P1327. Said there was piston noise. Told me none of it is covered and that I would be out of pocket almost $9,000.00 with a car that is 5 years old. Have a case open with Hyundai Consumer Affairs (Case#[XXX]) and have not heard anything back from them. I am needing to know if this should be covered. According to my research it should be.

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.

My vehicle has a very rough idle-vibrating at idle or stopped and not shifting properly-gear slipping. There is sluggish acceleration or jerking and the problem worsens while at a stop light/stop sign or at times when making a turn. The RPM goes between 200-300 when I accelerate to go from a stop and the car revs as it slowly hits 20 mph and then jerks into the 30-40mph on the streets. I took it to the dealer January 2025 where they could not duplicate the concern, and all they did was a TCM judder improvement update for the DCT. The problem was dismissed as being an issue associated with the DCT and was told that unless a warning light turned on or my car broke down on me, they couldn't do anything more. The service representative advised that if I am in stop and go traffic and the car starts vibrating or shaking, I should pull over the side and turn off the car for a few minutes before continuing on my way. It has been less than 2 months and I have to take it back to the dealer so they can run diagnostics on it again. Same issues, no warning lights on the dashboard indicating there is a problem, but I am not comfortable driving the car anymore.
