2022 Kia Carnival

Engine light turns on every couple months. The Kia either stops accelerating and goes into “limp mode” or gives code for misfiring cylinders. Took to dealership several times, they did nothing but reset battery so light goes off. Unsafe when driving my family around and has turned into an unreliable vehicle. SO frustrating for a new vehicle to have these issues.

When traveling on the highway, the vehicle would not shift into a higher gear limiting the control of the vehicle to accelerate to the flow of traffic. The transmission would not shift for approximately 1/4 of a mile and was stuck at a max speed of ~35 mph and it would not accelerate. This loss of control almost caused an accident and put my family and self at extreme risk. Eventually the vehicle did finally shift gears allowing us to accelerate with the flow of traffic (60mph) This issue with a delay in shifting gears has intermittently happened on prior occasion when accelerating from a full stop, however, this was the first time it happened at an accelerated speed. The vehicle is not safe to operate and was towed to a service center; however, the issue is intermittent and not easily reproducible -- making it even more dangerous as you do not know when it will happen next.

We have been having an acceleration issue for over a year now. The vehicle will be running fine and the randomly not go over 30 MPH. You could have your foot the floor and the vehicle will not shift or go above 3 rpm’s. This has caused us to be in many dangerous scenarios getting onto an interstate. This has almost caused us to be rear ended multiple times. Problem has be reproduced at the dealer and “repaired” though the problem continues to happen. Sometimes the engine warning light is on when it happens, others times it is not and happens with zero warning.

The contact owns a 2022 Kia Carnival. The contact stated while driving 45 MPH, the vehicle lost motive power without warning. The contact was able to stop on the side of the road. After several attempts to restart the vehicle, the contact was able to start the vehicle and noticed that the check engine warning light was illuminated. The vehicle was taken to the dealer, and the dealer stated that because the check engine warning light was not illuminated, the vehicle would not be diagnosed. On another occasion, while driving 65 MPH, the failure reoccurred. The vehicle was taken to the dealer and the dealer stated that the actuator needed to be replaced. The vehicle was repaired but the failure reoccurred. On another occasion, the contact stated while adjusting the driver’s seat to a higher position, the seat failed to remain at the higher position. The contact also stated while driving 35 MPH, the vehicle would not immediately accelerate. After several seconds, the vehicle accelerated normally. The vehicle was taken to the dealer and the dealer stated that the console, horn assembly, and an unknown part needed to be replaced. The vehicle was not repaired. The manufacturer was contacted but provided no further assistance. The failure mileage was 1,872.

1. When accelerating (while driving on ECO Mode) the vehicle starts to shudder at times. When using Normal Mode, the vehicle will shudder while the brake pedal is being used at a red light. Front windshield cracks easily and paint easily chips with no sign of rocks hitting the vehicle. Called Kia Service to get the car looked at and they said they haven’t heard of such issues. 2. Doors are supposed to retract when closing if motion is occurring. A family member almost got her leg pinned by the door and our child almost got hurt on the shoulder because the door kept moving in closing mode when she was trying to get inside the car. Whatever sensor it has, it doesn’t work. 3. Roof Mold on driver’s side came off the roof while driving the speed limit on the highway never to be seen again. The passenger side almost went flying too. 4. iPhone XR does not work properly when synced to the car. It connects and disconnects out of nowhere. It becomes dangerous when using GPS. Vehicle system kept saying it needed a new software to be downloaded. Went to the site and downloaded multiple rimes, called the Customer Service about 3-4 times and last person I spoken to told me to ho straight to the Service Dept at the Kia dealership to get the software downloaded. No one at Kia knew how to download the software. After multiple attempts and Kia not “finding anything”, decided to spend extra money and get a new phone to resolve this issue. I have to have a software downloaded to the vehicle.
