My 2021 Kia Sorento is waiting on a new transmission with no ETA. Thank goodness after it started driving rough and rocking back and forth while in park we took it to a Kia dealership. Dealership said we. needed a new transmission. I-??m just glad we caught it before we had total engine failure going down the road like the recall states.

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.

As I was taking off from stop sign car dropped into lower gear jerking car and lowered speed. Did this twice almost causing an accident. Knowing something was very wrong we proceed to Dealership. SUV stalled out 3 times on the way. Third time it stalled out was in front of service writer in front of dealership.This car has been very dangerous to drive from the delivery to now. It hesitates when you give it gas at stop and vibrates as you pic k up speed. This car is very dangerous to drive. Has been in shop for a week tring to figure out the problem. 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.

i have 2021 Kia Sorento Hybrid, which a regular message stating that it needs to refill inverter coolant fluid keeps coming up, even though the car coolants level is full. This is not a new problem for the all the Kia users that have this model. Also, Kia and their network of dealerships have known of this problem for over 1 yr and their standard answer is" we know its a software program, and will get back to you once the software code is fixed". Basically, they are dismissing the complaints and issues from the car owners. Also, this is poses a security and safety concern, since the warning light/message takes over the entire center console/display. Other relevant safety and security warnings/functionality is obstructed by it. Please force Kia to make this a mandatory recall for all Hybrid owners. There are thousands of customers impacted.

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.

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...

The inverter coolant refill light will illuminate at all times even with the system serviced. Kia has serviced the system but has no solution on how to stop the light. The light also blocks out any other warning that may happen on the dash. With the light illuminated while driving, it is impossible to determine if the system is empty to cause a fire or just a faulty light. The dealership has confirmed the faulty warning light. There are no computer codes associated with the warning light.

Less then 25000 miles. I was backing out of a parking place I heard some signal indicator beeps, put the car in park and saw a transmission engine light indicator lit. On the display panel were the options to make an appointment with a dealership or to call roadside assistance with the description of " a possible condition with your transmission control system has been detected. A full system check is recommended to be done when convenient. Please contact your local dealership for an appointment" I called roadside assistance to see if they were able to help me further understand and they could not and suggested I called the dealership. I drove the vehicle home and was hoping a Sensor may have gotten wet as we had a lot of rain and bigger than usual puddles. The next day I started my car the engine light was on again. I drove to the dealership (when I called them they did not answer in the service department). A woman came out to the vehicle and said she could not diagnose what was wrong but as long as I'm not having any difficulty driving, nothing feeling weird, or off that I can bring it in on Monday, two days from today, so we agreed. I went to one store and when I came out the car started and shifted into gear but pressing on the gas no power! it would not go forward it would not go in reverse, nothing! The diagnostic code from my Kia phone app is P1C2D03 I can't find anything about this code.

I have a -??21 Sorento hybrid. The refill inverter coolant warning light keeps coming on. The first time it happened was on a road trip. A local dealer told me to check coolant levels and when it was full, told me it was safe to drive. I had it looked at as soon as I got home. By that time, the light had gone off. They flushed and refill the coolant. It happened again within 3 weeks. I took it in again. The dealer inspected said nothing was wrong with vehicle. Safe to drive. Also said I was the second one of these they-??d seen. They were told corporate is working on a fix. I starting a ticket with Kia customer service. It-??s been 9 days and no response from them. I am counting on the dealers being correct and that it is safe.

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].

We had just received our Sorento back from being in the shop for 4 months due to being in an accident. Part of the repair work was to have the software updated and reprogrammed at a Kia dealership, which was completed. We picked up the car on Tuesday, Feb 15, 2022, and on Wednesday, Feb. 16, as we were traveling down hwy 27 in Lake Wales, FL, the alert began to ding and the hybrid warning came on, as well as other lights (I can't remember which ones). The car lost acceleration capability, but as we slowed and turned down another road, the car began to slightly accelerate very slowly. We were able to travel another mile, when the acceleration completely stopped. We pulled over to the side of the road and put the car in park. The engine was very rough. The message came on to leave vehicle in park to charge the hybrid battery. When we did that, the engine started for about 5 seconds, then shut off. We attempted this two more times, with the same results. We also tried to jump the car, according to the operator's manual, but it didn't work. We had to have the car towed to the dealership.
