2026 Kia Carnival Transmission and drivetrain Problems

“I have taken my car 3 times to 3 different Kia dealerships for this issue. First on 9/13/2026, then 10/13/2026 and on 10/26/2026. While driving at highway speed my vehicle suddenly begins to loose power and the check engine light comes on. This is dangerous for myself as well as other drivers.”

“When accelerating, the car feels stuck to gear up. After 2 seconds of loud revving, it would switch and have a prominent jerk motion that it finally switched gears. There have been times the car wouldn't go past 30 mph, stuck at the gear making a loud noise. This is dangerous! There's absolutely no way I can get on the freeway never getting past 30ish mph. I checked recalls for this vehicle and there isn't any. No warning lights in the dash.”

“After purchasing vehicle (4Sep25) the following week's notice wet spots in drive way first assumed to be from A/C but not the it is November and A/C is off the wet spots are still showing up. Checked under the vehicle and noticed oil all around the PCV tube. Took vehicle to Allentown Kia. They confirmed there is a oil leak but the leak is from the oil pan gasket. The vehicle has 400 ish miles on it and was i believe a quart low on oil by the time I took it in for repairs.”

“The contact owns a . The contact stated that while parked when the brake was depressed, press start button, when put in reverse, it says gear is selected, the vehicle stayed in neutral. This happens intermittently. The stop button was pressed, all of the instrument panel warning indicators would not illuminate. When pressing p for parking to engage parking, it appeared as if it was in park; however the vehicle unexpectedly reversed. The vehicle was able to be stopped. The vehicle was taken to the dealer where the issue could not be duplicated. The manufacturer was not notified of the issue. …”
