2020 Hyundai Kona Power Train

While driving under normal conditions, the vehicle’s dual-clutch transmission (DCT) failed to engage properly, causing a sudden and unexpected loss of propulsion. When the accelerator was pressed, the vehicle hesitated and did not respond as commanded, resulting in delayed or no acceleration. This occurred while driving in traffic at approximately 30 mph while trying to acceletate to merge onto highway and has happened multiple times. In some instances, the vehicle appeared to remain in gear but would not accelerate, and in other instances the transmission disengaged before re-engaging unpredictably. This created an unsafe situation, as the vehicle could not maintain speed or merge safely, significantly increasing the risk of a collision, especially in traffic or at intersections. The issue occurred without sufficient warning and continues to happen intermittently during normal driving.The vehicle was inspected by a dealership, which stated the condition is related to a clutch issue within the dual-clutch transmission and acknowledged it is a known issue affecting this transmission. The dealership further stated the issue would not be repaired because the vehicle is out of warranty.

The issue is when I'm decelerating to around 5 mph and go to accelerate again, there is a horrible grinding sound from the transmission and I can no longer accelerate. I then have to stop and re accelerate. This is dangerous if there is a car coming and I pull out and have to stop all of a sudden. I have 2 separate videos of the issue. The dealership won't fix it under warranty because they can't replicate it. The dealership won't even take a look at anything.

Letter below was sent to Hyundai corporate 7 Feb 22. They replied I should work with my Dealership to resolve the issue. Dealership cannot duplicate the fault. Vehicle has 7 speed DCT and currently has about 40k miles. "SUBJECT: 2020 Hyundai Kona DCT disengages and/or makes loud banging noise upon normal acceleration from standing stop. Occurrence is random but more prevalent in warm weather. ISSUE: While our Kona has been a mostly faithful servant over the last 17 months, including a trip from Florida to Oregon and back, it still, at random times, will violently disengage the 1st gear clutch, sometimes with a very loud 'bang.' Local Dealership mechanics cannot duplicate the fault, so what can be done? OPINION: For my wife in particular, this is a Safety Issue. When you step on the gas and the car begins moving forward but then BANG! and it coasts, bad things can happen. Like when you are trying to move out into fast moving traffic? The last time our Kona did this to me a couple weeks ago, the ‘BANG’ shook the car as violently as a collision, and I reflexively looked in the rearview mirror expecting to see an oil slick behind me. But nothing further happened and the car drove normally afterwards. Very disconcerting. NOTES: Don't get me wrong here. We like Hyundai vehicles and have owned two Sonatas, one Elantra, one Sante Fe and now, a Kona over the last 10 years. I love the' zip' from the Kona turbocharged 1.6ltr ‘mouse motor,’ the mileage is very good, and fit and finish are excellent. This is our vehicle of choice for all local trips and some longer ones." Help! Are there other owners in the same boat as I am? Is a recall pending?

Vehicle hesitates and does not accelerate from a complete stop, then jerks and changes into 2nd gear. Same hesitation and lack of power to accelerate occurs at 3rd gear. Causes a near accident when the car would not accelerate as I pulled into normal traffic

Transmission stutters and slips between 1-2k rpms, especially at low speeds and in stop and go traffic. I took my vehicle to the dealer. At less than 20,000 miles they said transmission wear is at 85%. Unacceptable performance and concerning that this will continue to degrade.
