The vehicle experiences a dual-clutch transmission shudder in low gears and at low speeds. This issue causes a sudden loss of speed in situations such as merging onto a highway, leaving a parking spot, or while driving at approximately 30 mph. The shudder occurs randomly and poses a serious safety concern. The problem first appeared in 2020 when the vehicle had fewer than 5,000 miles on it. Beginning in 2024, at around 20,000 miles, the condition began escalating rapidly, with the shudder occurring more frequently and with greater severity. All incidents have been recorded on dash cam and provided to the dealership’s service department. The vehicle has been serviced multiple times for this issue and was kept at the dealership for approximately six weeks in total. Despite this, the dealer refuses to acknowledge the problem, citing the absence of warning lights. When the clutch was adjusted at my request, the issue temporarily improved but returned about three weeks later. The shudder now occurs more often and with greater severity, frequently forcing the driver to pull over for safety. This ongoing transmission defect creates unsafe driving conditions, and the lack of acknowledgement or permanent resolution by the dealer further increases the risk to the driver and others on the road.

History of engine randomly lurching/ hesitation when shifting. Have brought car in when it stalled out while driving, or at light. Largest problem now is oil leaking excessively. KIA has not been forthcoming on their history with this issue on 2020 Tellurides. Have been dealing with this the past couple of months and needed to bring it in for 'checks'. Service tech said that ½ Quart of low oil after 1000 miles was not enough for KIA to flag; told me to come in at oil change time. He said I did not need to worry as it was still covered under 100,000 warrantee. After checking it myself after driving another 1000 miles, I found that it was low. I brought this in for immediate concerns. I was told to 'wait' as my Service Tech was not there that day. He called me the next day to tell me I should bring in when I can so they can write up an 'approval ticket' for KIA. I brought in the following week. Again he was off. I spoke with another tech who told me it was low 2 ½ Q of oil - this was a week later. I now have to wait for KIA to 'approve'. I was told this could take a week or longer.. I need my car. I asked for a rental and was told I may have to pay for it. This is frustrating and disturbing. I am told by other tech that I will probably need a new engine and I should not drive my car until it is addressed. This car is 4 ½ years old and has less than 70k miles.

The contact owns a 2020 Kia Soul. The contact previously received notification of NHTSA Campaign Number: 21V259000 (Engine). The vehicle was taken to a dealer, where an inspection was performed, and the contact was informed that the vehicle had passed the inspection. The mechanic stated that no repairs were needed, and the recall was removed from the VIN. The contact then stated that while driving 30 MPH, the check engine warning light illuminated, and there was an abnormal rattling sound coming from the vehicle. The vehicle was taken to a dealer for an inspection, and the contact was provided a diagnostic test fee. The contact declined the diagnostic test and took the vehicle to an independent mechanic. The mechanic determined that there was a defect with the piston oil rings. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 21V259000 (Engine). The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 92,000.

I was just driving then noticed lack of acceleration and the engine light flashing. Loosing acceleration mid driving posed a great safety risk because no other drivers would know the issue I was experiencing and risked causing an accident. The vehicle was taken for a fault code reading which indicated a knock sensor code, later it was inspected at the dealership who confirmed an ECU issue. The police or insurance have not inspected the vehicle for this particular issue.
