2021 Kia Sorento

My electrical system failed. While on park I was unable to shut of the vehicle using the engine start stop button. After waiting for the vehicle to automatically turn off. The vehicle started trying to restart itself. The negative battery post had to be removed for the vehicle to stop. The entire safety system failed and all warning lights are still displayed on the dash. The backup camera and radio display went completely blank and was unavailable.

I had purchased my vehicle in January of 2024. At the time the car drove great. Fast forward a few months later and that’s when the issues started happening. I would go to accelerate the vehicle and it’s like the car didn’t want to go anywhere. I would have the pedal down to the floor and it wasn’t moving. At first when it happened it was sporadicly, and I thought ok it’s a new car maybe that’s just how it drives. But then when I was pressing the gas pedal the engine would revv up but then continue to rev even when the car was moving, like it wasn’t catching the gear. So I had enough of just thinking it’s the car and I had my own mechanic look at it and he mentioned CVT transmission slipping. So being still under warranty I took it into Kia this past December and explained the loss of acceleration, it eating gas, and how I truly do not feel safe. Well of course I was told there is nothing wrong with it, and that it learned my driving habits and that I possible keep hitting the shifter in manual. I had videos of the rpms revving up and the car not moving, and they didn’t want to see my videos. I was just a few thousands miles from my 60,000 mile second owner warranty and not sure if that’s why I was told there was nothing wrong with is. This vehicle is truly a hazard as it does not move on acceleration on the highway and feel like I will get into an accident because of it one day. Kia really needs to address the issue before something really bad happens to someone. I apologize but it will not allow me to upload videos of the issues before and after going to Kia and how there is still an issue.

I started the car and it started having a hard time shifting around 13 and 30 miles an hour. And had a lack of power. No lights were on. Took it home and shut it off. The next day started the car and it told me to put it in park and the check engine light came on. I had no acceleration when in drive. Checked for powertrain recalls for my 2021 Kia sorento sx awd and 0 recalls came up for my vin #. It’s definitely a transmission powertrain issue.

I bought the car at 28k miles certified pre owned at jake sweeney kia in Florence ky. I had taken the car to the service station multiple times complaining of a clunky transmission. Things got worse and a whine from the engine bay occurred. At this time kia replaced the transmission at just under 42k miles. After having the new transmission about 500 miles later this issue is occurring again. Within 50 miles of replacement I went back to the dealership complaining of the the same clunking issue. At this time the dealership told me they could not replicate the problem. Now just a few hundred miles later the problem is extremely worse. I once again visit kia were they tell me again they could not replicate the issues. At this time I asked the service advisor Donavon to ride with me and I will point out the issue. Within a mile of our trip the problems occurred and the advisor noted the issue. I now am driving the car and waiting for a loaner from the dealership so they can yet again diagnose the issue which may result in another transmission replacement

On three separate occasions, after starting the vehicle, the car cannot be accelerated above 30 mph. The Idle Stop and Go (ISG or Auto Start Stop feature) light flashes orange, but no other warning symbols are illuminated. After safely moving the vehicle off the road, I have to turn off the engine, wait for 2-4 seconds, and restart the engine. Once the vehicle is restarted, the vehicle accelerates normally. This issue has happened twice in the past month. I plan to take my car to a Kia dealership for an inspection, but since this problem happens randomly, the Kia technicians may not be able to reproduce the problem. I purchased this vehicle used with about 77k miles in December 2023. I first noticed this issue in April 2024. The vehicle now has a little under 98k miles recorded.
