The drive mode selector in my Kia Sorento was found to be defective. The selector forces the vehicle into "Eco" mode on startup regardless of the previously selected mode. This creates unexpected throttle response at startup given the manual states leaving the vehicle in other modes (such as "Smart" or "Comfort") will be retained on key-cycle. The specific incident in question produced unexpected throttle response while backing into a highly-trafficked road and resulted in unexpected proximity to oncoming traffic. The selection module has a further failure state: the backlight lamp showing selected drive mode has gone out preventing ready identification of current drive mode.

The panoramic sun roof opens but will not close. it takes 6-12 attempts to get it to close, it will move to where its an inch away from closing then reopen. Kia has recalls for this make and year but says my car is not affected. attempting to get it to close is very distracting and frustrating taking focus away from driving.

My 2021 Kia Sorrento has shut down and died while on a Highway drive 2 days in a row. The engine light comes on, the oil light comes on, and and the phrase “Engine Off. Shift to N then start engine” comes on. Prior to this, other issues were happening. Originally, my automatic start wasn’t working properly, and a Kia service advisor told me to “turn that feature off”. After that, while driving down the road last month, all symbols on my dash began flashing and the phrase “Check forward safety system” appeared.

I received the recall notice essentially telling me not to drive this vehicle and park it away from my home or other vehicles. When i contacted KIA I was told all they are currently doing is a reimbursement of up to 40 dollars a day for a rental while they figure out how to fix this. Rentals here are over 100 dollars a day and when I told them that I was told the additional money would be on me. My car is still under warranty but they expect me to pay for their issue. Due to this I am still driving a car they recommend parking and will continue to do this. If they were actually concerned about this they would fund rentals and not make me pay for them up front and for over half the cost. When I contacted my dealer they directed me to the manufacturer, no help at all. I am only still driving this car because it would be too expensive for me to fund a rental for an unknown length of time.

Refill inverter coolant notice comes up after routine oil change and downhill control turns on without me turning it on I have to shit my vehicle off in order for the brake control to turn off, available for inspection upon request. This notice interferes with me seeing the digital speedometer. Coolant was checked by dealer no leaks found, was told to wait patiently until a fix is available. No prior issues until I took it in for an oil change with the dealership.

Vehicle went into limp mode suddenly while driving on the road and would only go 10 mph. We were able to pull vehicle aside and within a minute the car would not move. Check engine light came on with a warning message to pull vehicle to the side of the road. We were able to drive the vehicle home 7 miles after waiting about 1 hour after the issue and the next day drove it to the dealership. Car has been at dealership since 8/8/22 and service advisor and Kia engineer have yet to figure out what went wrong. We have no eta as of today when we will get car back. This issue is concerning as the vehicle came to a complete stop with traffic around us.

I have owned this vehicle for about 1 yr & 7 months now. it's been great but all of a sudden last Friday, the dashboard started producing an engine overheat warning with an alarm sound when I was driving under normal conditions. So then I pulled out of the highway and went to the nearest parking lot, and checked the engine. The coolant color was normal & max level. no sign of leaking. Then we resumed driving and nothing happened. later on the way back home... the same thing happened. The alarm sounded for a while and the temperature indicator reached red at the max level then it went away. it was already too late for us to reach out to either dealership or KIA, so I was going to get in touch later. The next day afternoon, I got a diagnostic appointment for the coming Wednesday with the nearest KIA dealership and went out to take care of a few other stuff. The alarm sound with the temperature gauge reaching the red max level happened again after merging into the highway, and it went off after a while. This occurrence has happened 3 times already and I'm a bit worried that it may happen again and something else may happen even though the engine and other fluid levels were fine based on the visual inspection. Not sure if this is fixable...

Car has been having issues with not starting many times also dealership was contact also was serviced and still having issues.

After being driven for 45 miles, with no problems, then parked for 2 hours, then when I started to drive, dashboard lit up "PULL OVER SAFELY IMMEDIATELY". I pulled over, shut car off and restarted. Same notice appeared. Tried again and nothing appeared. I attempted to move the car and it would not engage in drive or reverse. Shut car off, started again and still would not move. Then was towed to a KIA dealership. Upon inspection, I was told it needed a new transmission. Vehicle had 5,606 miles. Car is at dealership since April 4 waiting for new transmission. I was told there are other KIA's also waiting for new transmissions. If I had been driving and car suddenly shut off, it would have been very dangerous (there are many such reports online where people have experienced this). There is documented evidence on line that others with low mileage have had this problem dating back to April 2021. This car needs to be recalled and significant changes made. The car is available for inspection at the dealer's location, Lou Sobh Kia, 1135 Buford Road, Cumming GA 30041 if you need. You can reach me at[XXX] or via email [XXX].

Transmission failure at 9108 miles. Car was turned on and error code stating of some form of a transmission failure. Odd electrical sounding issue in engine bay as well. If the transmission had failed while I was driving I could have gotten into a serious accident. Kia is already notorious for failing transmissions in their other vehicles. This car maybe no different.
