“We have been having persistent safety issues with this vehicle. The issues have ranged from unsecured gas cap to loss of power. We’ve also had severe transmission issues where the car will not shift out of first gear. This happened on the Garden State Parkway and nearly caused an accident as the car wasn’t able to go above 27 mph safely.”
NHTSA complaint #11740593, filed 2026-05“I was stopped in in the left turn lane with my right foot on the brake pedal. Suddenly the car began to rapidly move forward. I jammed my right foot down and stopped the car, avoiding an accident.”
NHTSA complaint #11695410, filed 2025-10“For the third time the 2025 KIA Carnival Prestige I own lost power while driving on the interstate! Without warning, the vehicle would no longer respond to the accelerator pedal. No matter what I did I could not get the vehicle to accelerate past 35 mph. The minimum speed limit on the interstate is 45 mph. I had to immediately engage my hazard lights and make my way over to the shoulder of the road from the passing lane. This was a dangerous situation for me and my family and others on the highway. Warning lights came on, check engine light, charging system, and a maintenance service message. …”
NHTSA complaint #11740406, filed 2026-05“The battery is draining due to external things but it’s not attached to anything and now all screens in the car flash on and off and go black including speedometer”
