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.

Kia has been chasing transmission problems on this vehicle for several Months and now the transmission has completely failed.

- Palatka, FL, USA

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.

while driving car dropped to 20 miles pe hour pressed gas harder and rpm stayed at 2 and car failed to accelerate, Loss of driving power. It intermittently will drop rpms and lose speed with no warning no light or indicators. This is the 2nd transmission the original failed on 09/11/21 with only 12,000 miles on the car and had to be replaced. this transmission only has 14, 00 miles on it and is a replacement from the Valley Kia dealer. This car is unsafe to drive you dont know if you press the gas pedal it will actually accelerate or stall.

I have a 2021 SX with 6000 miles sitting at the dealership with a failing transmission. yesterday September 2, 2022, my vehicle lost 100% of power and I was left at a traffic light with no power. The dashboard said, "Stop safely immediately". The engine light came on and thank God I was not on the highway. Got towing service to Kia Dealer in Houston. It is a very dangerous situation for any driver to lose all power suddenly. I went to the internet and this is a common problem with this model. It is related to the DCT transmission.

Vehicle is not shifting properly. The vehicle is hesitating on shifting up and have a very hard down shift. When vehicle was brand new this was mentioned to the dealer and they said it was "normal" for these "new" transmissions. This issue has now since gotten way worse. When sitting at a stop sign and needing to accelerate to get out onto the roadway and wheel is slightly turned on "dry" roads the traction control light will come on and vehicle will not accelerate. This is a very BIG safety concern as myself and my kids use this car daily! This problem has been made aware to dealer but only to be told its "NORMAL" this is not normal its a big risk of possibly getting myself or others into an accident. The vehicle is going to be relooked at with another dealer 8/30/22 as it has gotten worse and im concerned of the safety of myself that this vehicle may malfunction causing as accident. I have also looked at other reports of these 2021 Sorentos and seeing a pattern with the transmission issues of them.

Car fails to shift gears. Will not allow to switch to manual and get stuck in first gear. Car has less than 12,000 miles

- Layton, UT, USA

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.

- Mesa, AZ, USA

On my way to the grocery store less than a mile from my home an alarm and dash alert popped up "SAFELY STOP IMMEDIATELY." The vehicle was stuck in first gear and the rpms revved up. Almost immediately I lost power and it was stuck in neutral even though it was in drive. Then the engine shut down. When I restarted it I could not move. This is extremely dangerous and should never happen. The vehicle has 17,802 miles on it and now my wife and I are afraid to drive it. After sitting for about 20 minutes I was able to start it and return home. It has not moved since. We called the dealer and they were backed up for over a month on service. This is a new vehicle? Upon investigating this issue I found just on one website over 43 reports of the same incident. One person said that a dealership has an entire row of these vehicles with the same problem and transmissions are on backorder. It's been 3 days and still waiting for a reply from my local dealer. This is not safe!

1) Automatic Braking: Twice, Car has auto braked in the middle of a 4-way intersection when a car was stopping at the light. Car has auto braked in the middle of the 3rd lane (fast lane) on the highway during rain. Car has auto braked multiple times when reversing out of a parking spot. In one of those incidents, I have to drive forward in order for the car to move; turning it off and on does not reset the vehicle. The auto-braking while driving especially on the highway causing rapid decceleration could result in another vehicle rear-ending me. 2) MANY transmission issues: jerky transmission, car moving backwards while in drive (usually uphill, doesn't have to be steep), car stalling in park or when going up steep hills, traction control kicking on and engine downshifting (even though the roads were dry).

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...

Vehicle randomly losses power when trying to accelerate from a stop. This creates a risk of being rear ended or struck while attempting to merge into traffic. Power loss is 100%. May last from a couple seconds to several minutes. No warning lights come on. The vehicle is currently at the dealership awaiting diagnosis which I was told could take several weeks due to a -??backlog of vehicles awaiting repair and a shortage of repair technicians-??. Dealer refused to offer a loaner car and Kia will not provide a loaner or rental vehicle until the car is diagnosed by the dealer.

Vehicle randomly looses power to the wheels while driving vehicle. This has occurred while in drive and reverse. Engine check light is lit (not blinking) and message appears on instrument panel of "Stop Safely Immediately" at time of occurrence. This first started on 7/4/2022. This occurred while in heavy traffic which put myself in a dangerous position as it did for other drivers around me. Vehicle is at the dealer service department for the third time. They are having difficulty recreating the issue. On first visit technician found history code P1C2D03 described as "Incorrect Gear Ratio". Transmission software was updated, I picked up car on 7/7/2022 and did not make the 4 mile trip home before it occurred again. The last occurrence was on 7/27/2022. Problem occurred while backing out of driveway.

- Plano, TX, USA

Vehicle slams into gears, jerks forward when accelerating, hesitates a long time when reversing then changing to drive(extremely dangerous), and when in park and not turned off yet it surges or revs slightly and you can feel it trying to go forward. At first these things were rare but then became occasional and now after a year they have become constant. Dealership says I need a new transmission and they may have my car for two months or more! Have also had a dead battery twice already with nothing left on or plugged in.

- Longmeadow, MA, USA

Transmission failure-?"car stopped driving mid-drive. Thankfully I was driving on a suburban street at low speeds, but it could have been dangerous in another circumstance. The car was towed to a Kia dealership and they claimed it was fixed after a week, however they could not successfully start the car when I went to pick it up and I had to leave it at the dealership. Additionally, the paperwork I was given that detailed the service did not match the records the service department had. After several weeks and despite attempts to contact them, I have received no updates. The check engine light came on after the initial failure.

- Dallas, TX, USA
