    Transmission quit engaging and had service light that said to stop vehicle immediately on September 24, 2022. The vehicle was then towed off to nearest dealer for inspection/diagnosis. Software update was applied on September 30. We picked car up on Oct 01 and drove home with no issues. On Oct 02, I started noticing car was not shifting properly from 2nd to 3rd gear. I had to delicately drive in a certain manner to get it to shift to next gear. Oct 03 engine light came back on, had vehicle towed back to dealer. Oct 04 received call from dealer and after diagnostic was completed, they said they had ordered a new transmission for us with an unknown ETA. Safety of us and others was put at risk due to the transmission behaving erratically. No warning lamps, or messages had been received prior to transmission disengaging initially on Sep. 24. However, there were some symptoms prior to that incident, so I had a strong notion that it was only a matter of time until we were going to experience a transmission issue.

    On Oct 5th, 2022, I was driving home from work on Interstate 75, when I heard a chime from my dashboard. When I looked at the dashboard there was a message to “stop safely immediately,” and the check engine light came on. I happened to be at my exit and took the next exit off the highway. Whiling getting to the off ramp the vehicle randomly shut off. I stopped the suv with the brake with no incident. Thankfully no one was behind me. However, the car wouldn't turn on. After several tries the car turned on again. I immediately drove it to kia which was about 2 miles away for immediate service. They did a multi-point inspection, checked fluids. The tech came back saying the vehicle need a software update. They did a software update and returned the suv. I was told everything should be fine. Within a day of the update the check engine light came back on. This time when I accelerate the RPMs are going up but the speed is not increasing. The Sorento hesitates to accelerate from a stop. The vehicle has issues shifting in the lower gears until it JOLTS forward. I returned the Suv to Kia where now I am told it needs a new transmission. I was given no indication as to when this fix would happen. I ask for a rental car they have none. Tech at Kia says its okay to keep driving this suv. Did I miss something? As of Oct 22, they want to recheck transmission fluid which they have already checked. I have been given the run around with no fix for the problem insight.

I have complained to service department about this ever since I have owned the car. Thanks for any help. I know I,m not the only one with this problem. Pat McGrath.

    As my vehicle was in drive and I was actively driving, an error displayed on the dash stating to "stop safely immediately." The vehicle would neither accelerate nor decelerate and would not generate any RPMs. The check engine light came on, went off hours lately and the vehicle appeared to perform normally thereafter. Nonetheless I had the vehicle towed to the dealership and was told they were unable to duplicate the error although. I was told that although they could download the code for the error, it was unlikely that Kia would replace the faulty sensor that needed replacing as it was located on the side of the transmission. I was told to video the issue if it ever happened again. 7 days later, the exact same thing happened while I was in the middle of an intersection with my children. I leased this vehicle in May of 2021 and this issue occurred in July 2022 with 7800 miles on the odometer. There were zero issues with this vehicle prior to this and I have all service records and video footage of the incident.

    My vehicle was in my garage and I noticed a crack in my windshield. Nothing hit my windshield and there are no knicks in the glass. The crack starts all the way at the top of the windshield and the crack is spreading very quickly. I bought this vehicle used on 7/12/22 and I only put 789 miles on it since purchasing it.

    The transmission failed; it is at the dealership awaiting a replacement transmission, and, if needed and if possible, I would authorize for it to be inspected. While in a parking garage, the instrument cluster displayed a "Safely Stop Immediately" message and a check engine light, and the vehicle began to lose momentum and roll to a stop, regardless of accelerator input. The problem was was replicated and confirmed by a Kia dealership. The vehicle has not been inspected beyond the service department at the dealership.
