I began having issues with my car rolling forward around a foot or two after coming to a stop. This was very disconcerting as it meant that I could not be sure if when I stopped, I would not roll forward into another car or something else. It also twice began having a difficult time shifting automatically after idling for 10 minutes, I switched to manual and eventually got it to shift that way. I took it into my local dealer to have it looked at and they assured me this is just how the transmission is. It was driven only a few times over the next two weeks, then I went to pick up my daughter from school and after she got in, it began having a serious issue with shifting, only shifting automatically once RPMs reached over 5,000. I could not get the manual shifting to work at this time. Additionally, the engine light came on. We slowly made it home and I made an appt to have the dealer look at it again. I have now been told I need an entirely new transmission.

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.

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].

The contact owns a 2021 Kia Sorento. The contact stated while reversing, she noticed a trail of oil on the ground. The contact parked the vehicle. There were no warning lights illuminated. The vehicle was taken to a local Pep Boys who informed the contact that oil had leaked onto the skid plate. The engine oil was refilled and the contact drove back to her residence. The manufacturer was notified of the failure and assisted the contact with towing the vehicle to the dealer. The dealer diagnosed that the oil drain plug had fallen out causing the oil leak. Additionally, the dealer diagnosed that the lack of engine oil had caused the engine to fail, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but informed the contact that the vehicle would be repaired at her own expense. The failure mileage was approximately 10,394.

In 2 instances the car shut off without warning. Once After the car had been shut off, ( would not restart.) Then again while the car was in drive sitting at a red light. (Engine shut off without warning). Dealership could not figure out cause. When trying to restart the dash lights would come on with all codes being thrown as failure for multiple systems but engine would not start or try to start. The car did think it was running though as the dash would say car will shut off in alloted time frame that was set in car settings. Both times after the car being towed to the dealership and sitting for the night it started back up next morning like nothing ever happened. I ended up getting traded out of the vehicle at 18,500 miles after owning the car for 30 days. I’m assuming that’s why previous owner traded it. It’s a lemon.

The vehicle stutters before it comes to a complete stop and creates a panic feeling thinking it is not going to stop completely. Have had the car into KIA for two separate inspections and they just tell me it's due to a dual manual clutch working in and automatic car. I know I am not the only one experiencing this terrifying sensation on a brand new vehicle. KIA won't do nothing until the transmission completely fails. Even their master tech indicated there are issues with these transmissions causing shifting and breaking issues.

2021 Kia Sorento EX had 3,196 miles on it when the transmission failed. The car was driving down a street when it lost speed and alerted driver to pull over. Driver had seconds to pull over before car completely stopped among traffic. Had the car been in heavy traffic, it almost certainly would've resulted in a collision from behind, especially at high speeds. The vehicle is currently at the dealership awaiting shipment of a new transmission. The vehicle has been expected by Kia dealership. There were no warnings of transmission failure before it failed, only once the problem was occurring in real time did driver receive an alert to pull over and a code regarding powertrain issues. Kia dealership mentioned that they had "a whole wall of cars with transmission issues" which conveys that this is a wide spread issue among their brand. If that is the case, it needs to be investigated and a recall needs to be issued.

I was on a straight road no cars around the collision sensor went off and slowed me down. Another time it kept slowing the passenger side wheel down as the traction control was going off it did this 2 separate times. Got down the road some and it did it 2 more times but with the driver side. Last week I pulled into my drive way and was in park when it started telling me traffic was coming from the left, like I was about to back into something, I can't remember if I had shut it off at this time due to someone had fell out of the 3rd row when her foot was caught in the seat belt trying to exit the car. I called my nearest kia dealer and was told they were so far behind and since I did not buy my vehicle from them it would be last. I asked if an accident was to happen who would be responsible and he couldn't answer me.

I've had a concern for last several months with my transmission not shifting from 1st to 2nd gear. A new car with 100,000 mile warranty shouldn't be having transmission issues, so just started paying closer attention to ensure it wasn't my imagination. Gears not shifting became worse & more noticeable. On 2-21-2022 (on way to work), the transmission wouldn't shift from 1st to 2nd and then 2nd to 3rd gears. The RPMs went to 4,000 and 5,000 respectively. No lights are showing. I noticed a beep (like a seatbelt not engaged) that sounds 3 times prior to the transmission issues. Nothing in seats to activate a "seatbelt not buckled" sound. I pulled over, shut car off, sat for a few minutes & restarted the car. Same issue. The car was not moved again until 5:15 p.m. to head home from work (35 miles one-way commute). I pulled out onto the highway and transmission again rev'd to 5,000 RPMs. Pulled over and shut car off again. Car in park, restarted the car, and the car lunged as if going into gear, but I was in park. On 2-22-2022, same issue as the day before. Still no lights coming on. Called dealership & had Kia roadside assistance tow the car. Dealership kept for 3 days and could not duplicate the error. On 2/27/22, drove to church & had same issues. Returned home, put car in park in driveway (still running), the car shuts off and restarts on it's own.

On January 17th at approximately 1 pm I was driving on Rt. 12 in Cordelia, California when I heard a loud explosion coming from the car's rooftop. I pulled over and discovered that my closed sunroof had shattered. There was no indication whatsoever that anything hit the glass. There were no vehicles in either direction less than 1200-1500 feet from my car when the sunroof class exploded. I assumed this would have been a warrantee claim as the car just approached one year old. Unfortunately, the manufacturer, Kia, denied the claim. I am now appealing the denial. Needless to say, I will never be comfortable driving this car with the sunshade open since that is what saved us from the shattered glass.

Exploding Panoramic Sunroof: Was driving about 50 miles per hour on a highway in Northern California. No other vehicles within 1200-1500 feet in either direction. Was not driving under an overpass when we suddenly heard a large explosion and a rush of air. We pulled over to the side of the road and noticed that the sunroof glass had exploded and was completely shattered. We strongly believe it was NOT a result of an impact from a foreign object unless it literally fell out of the sky which seems extremely remote. We heard nothing until the explosion. No other damage to the car's hood or roof. No indication whatsoever that anything hit the car. The car manufacture, KIA, denied the claim. Fortunately no one was hurt since we had the sunshade closed and no other cars were nearby to get hit by the shattered glass. This could have been a dangerous situation.

I noticed a clicking sound coming from the front driver's side wheel well. I also noticed a burning smell coming from the engine after driving the car for 10-15 minutes. Shortly thereafter, while driving the vehicle the RPMs seemed too high for the power being put out in the vehicle. It was also acting sluggish and felt like it was going to stall when at a stop sometimes. At one point, the check engine light came on but then went off after driving it for a few miles. I took it to the dealer's service department and they discovered that there was a fault in the transmission and it needed to be replaced. This is a 2021 Kia Sorento with only 6,500 miles on it.

When making a turn and accelerating from a stop (pulling out into traffic from a parking lot), if there is any loose gravel or potholes, the traction control system engages and renders the vehicle unable to accelerate. This has almost caused accidents on multiple occasions and has been described by other drivers on this forum: https://www.kia-forums.com/threads/sporadic-issue-no-acceleration-from-stop.350565/page-7#post-2083617

Tonight was the first time I drive this car in the snow. I was going downhill doing 5 miles per hour, I even downshifted to hold vehicle back, and the brakes totally locked up on me. I couldn't turn the car, it slid straight across the road, at a "T" intersection, and I crashed into a sign, and continued to slide down a hill on someone's property. In all my years driving this has NEVER happened to me. We have been complaining to Kia about the brake system on this car for months. Something is wrong with this car.

1/2/22 HORN-when I attempted to lay on it due to being cut-off, it was at this time, and continues to be inoperable. 1/4/22 Reported to Destination Kia, Service Department, Albany, NY. ACCELERATION-When pulling onto a major highway where the speed limit is 55mph, from an entrance ramp, my vehicle would not accel above 32mph. I do not recall any warning lamps. I was forced to pull off to the shoulder of the highway where I shut my car off and restarted it. The problem corrected itself. On the second occasion, I was driving in an area where the speed limit is 30mph, my vehicle would not accel (I cannot remember my speed); I do not recall any warning lamps. I was again forced to pull over to the side of the roadway where I shut my car off and restarted it. The problem again corrected itself. 1/4/22 Reported to Destination Kia, Service Department, Albany, NY Kia cannot get me in for service until February 2022 due to a staff shortage!

The car drifts from right to left all the time on any road surface. This was addressed at about 2,000 miles months ago and they could not get it to steer straight. I brought this up on the oil change visit and the tech never addressed this at all ! The dual clutch transmission does not shift properly. The vehicle larches hard into reverse, feels like it will sometimes stall when starting out from a stop sign or traffic light. (This is dangerous) The idle goes up and down from 750 RPM to 1,100 RPM when the car comes to a stop. (This is dangerous) The brakes feel like they are weak. (This is uncomfortable at best) There is a lot of wind noise at 45 MPH and up. Had you do a $65.00 oil change. When I got home, I checked the oil and it's at least 1/8 quart short. I have not had time to come back for your techs to add more oil yet. So, your tech did not address issues (1) (2) (3) (4) at all. Instead, he wrote up the issue (2) as being normal for that type of transmission. After your service advisor Joshua Mills saw I was very dissatisfied with the lazy diagnosis, he took me to J.D. McClure with the list of problems I had outlined to your company. JD explained he was brand new at KIA and did not have KIA experience which was disheartening at best. I asked that he contact KIA corporate to have a certified KIA rep come look at this vehicle. He assured me he would do so and call me back to see if and when a rep can come look at my vehicle.

Hello, My 2021 Kia Sorento SX was purchased new and it currently has 1917 mileages on the odometer. After purchasing the vehicle I have noticed a very noticeable noise which seems like coming from the transmission. When I slow to a stop a big clicking noise comes from the transmission. This noise is concerning regarding a safety stand-point and to be honest it is really annoying. I have read some other comments online and it seems to be an issue around this certain make and model. I have been to a Kia service center on two separate occasions on this issue. At this time the service department stated they can not assist me moving forward unless I escalate this to Kia Support which I plan on doing. Thank you for your time.

2021 Kia Sorento SX Prestige (XLine) did not want to shift on its own. When it was taken to the dealership, SME's reset the check engine light, drove 1 mile (total) and informed us there was nothing wrong with the vehicle. They were able to see a power train code (transmission fluid level pressure) within code history however they did not drive it long enough to replicate the code. Transmission fluid levels were checked ( 89% full) and was topped off prior to releasing the vehicle back to us. After driving about 40 miles, the vehicle was taken to the store however, went limp in the middle of the road. The vehicle would not move (no matter the gear) and after turning off the vehicle and turning it back on the vehicle would not budge. The vehicle was forced to move after revving up the vehicle to 5K RPMs the vehicle started to drift. During this time, the D symbol and R symbol would blink repeatedly. I put it in manual mode and instead of showing the gear it shows an " S ". Thankfully this occurred on a military base however, if this occurred off the base I believe I would have gotten into an accident causing serious bodily injury or worse. Currently, the check engine light is on and I do not feel comfortable or safe in the vehicle.

Within a 2 month period after purchasing this vehicle, the windshield has cracked twice. First time was more understandable as a larger sized rock hit the windshield right next to the pillar on the passenger side creating a roughly 4” starburst crack. That one was replaced and 2 weeks later a tiny pebble kicked up and created a small chip on the upper corner driver side. Within about 30 seconds the chip spread halfway across the windshield. These new windshield seems to be extremely weak and falling in line with the issues the Telluride had as well with the Kia acoustic glass.

The vehicle has a dual clutch transmission which causes the vehicle to lunge forward at idle. The transmission also "slips" at times during hard acceleration and results in very slow acceleration when entering a highway on a ramp or making way across an intersection. The transmission also shifts extremely hard when coming to a stop and then lunges requiring additional braking. This presents a safety issue when crossing an intersection or coming to a sudden stop in stop and go traffic. The vehicle has 10,000 miles was inspected (and reproduced) at the Kia dealership where I purchased it, and the service department states that the transmission is working as designed, which I believe since there are numerous complaints about the same issue on line and Kia forums. The newest issue (about 2 months old) is that there is a whining noise that appears to be coming from the transmission during acceleration until the transmission shifts into another gear. There are no warning lamps - the issue has been occurring since purchased in May 2021. It appears that this issue is with the dual clutch 2.5 turbo models across the Kia line.

When coming to a parking lot stop the vehicle skips or jumps and it can be felt on the floor board. I took it to get inspected at a Kia dealer who was able to identify the problem being my transmission and not the brakes. He informed me that Kia considers this a “normal condition” and that there was nothing they could do about it. This is extremely alarming and concerning that Kia is not concerned about transmission issues in their brands. There are no warning lights that come on. I feel unsafe driving this vehicle in fear of the transmission tearing up completely or running into the back of another vehicle or object. I drive on a busy interstate everyday for work and driving this vehicle in this condition is not safe in my opinion.

In traffic at a stop either needing to make a turn or just accelerate forward, when passing over an uneven surface (pothole, sidewalk curb from exiting a business), the accelerator does not respond to the pressure being applied and the vehicle barely moves even with pedal nearly to the floor (like crawls 1-2MPH), the traction control light blinks, to get across the intersection or junction and then it suddenly performs as if nothing happened. This is very dangerous as the vehicle is almost practically stalled and all you can see is oncoming traffic approaching. It is very hard to replicate but occurs at the most unfortunate times. The vehicle was just at its' first service appointment where I escalated the issue to the service department. They claimed they could not replicate, but they knew what I was describing and said there was nothing they could do. I also asked if they could ride with me so I can try to replicate it, but they declined. However; this is a safety concern.

On Monday 7/26/2021 I heard a popping sound and discovered that the windshield of my 2021 Kia Sorento SX sustained an approximate 2–3 inch starburst sized crack that proceeded to spread overnight while parked in the garage. The crack increased to about 6 inches long.

While inspecting the crack this morning , running my fingers along the damage glass both inside and out, I could not feel any divots. The glass to the touch was as smooth as silk.

It is not possible to disengage SCC and use regular cruise control. This has been brought to the attention of the dealer from where the car was purchased (who has been working with us non-stop) as well as by me to KIA via their website. The dealer's service department has inspected it and cannot find a way to disengage the SCC. (Other safety features built into the car can be turned off). KIA is balking at finding a fix. I cannot use cruise control in this car without also accepting the SCC feature. I find it dangerous unless it is what I want engaged. I prefer to be in control of my vehicle and do not want the car adjusting my speed for me. If I'm approaching a vehicle and signal to pass, but first get to close to the vehicle I wish to pass according to the vehicle's software, the car slows down as I move into a passing lane. Even if I have plenty of room for someone who may already be in that lane, my vehicle slowing down until the camera and software determine it's 'safe' again poses a problem. I can give other examples, but am sure you get the idea. Suffice to say, other brands of vehicles have a way to disengage adaptive cruise control features. KIA's manual states it can be disengaged, but as stated, those directions do not work. KIA needs to make this right. Since I need to give a date nex

On Wednesday June 2, 2021 around 12:15pm I was leaving a teacher summer workshop and I started the car as usual, no issues, and proceeded to leave the parking lot to make a right turn onto the street. I was about a mile away from home. As I proceeded to hit the gas the car moved forward into the street then failed to shift into the next gear, which left me stranded with traffic quickly coming up behind me. I turned the wheel really hard to get as close to the curb as possible. I proceeded to press the gas pedal all the way to the floor and nothing happened except high rpms around 3-4k. I looked at the dash to see if there were any warning lights, at the same time I am pressing the gas pedal trying to get the car to move forward. It suddenly moved forward so I merged over to the left lane, with traffic coming up behind me, and it happened again. It failed to shift into the next gear and seemed to be stuck. I am moving forward about 1-2 mph. I stop in traffic and within 15 seconds it caught second gear and moved forward and I was able to make it to the middle lane. The Sorento started to act normal, shifting gears and moving forward, so I proceeded towards the light to make a left-hand turn. I waited until all the oncoming traffic passed by to make my left-hand turn, then I hit the accelerator and it lurched forward and wouldn’t shift into the next gear, it just continued to rev to 4k. I’m coasting along at about 1-2mph trying to get through the intersection so I don’t get hit

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
