NHTSA Complaint #11426151 — 2015 HYUNDAI SONATA

My Sonata Eco is a 2015 model with less than 46,000 miles. I take it for scheduled maintenance at least twice every year since I purchased it. The vehicle was experiencing stuttering, vibrations and lack of acceleration, most frequently when turning, moving uphill or early after startup. The stuttering would vary in it's intensity, from barely noticeable to strong enough to shake passengers. Sometimes when performing a turn, my car would not be able to accelerate, leaving me in the path of oncoming traffic until it would start working again. This would also occur when travelling uphill. No warning lights or other messages were given by the car. After taking it to the Hyundai dealership they informed me that my transmission was faulty and would require a full replacement. They specifically mentioned it was a mechanical issue with the dual clutch not engaging properly. All electronic/software in the vehicle was confirmed by the dealership to be up-to-date so this was purely a mechanical issue.
