2021 KIA SORENTO Complaints

Engine stall while sitting in red light twice in one month. I had to put vehicle in park and restart the vehicle to get the vehicle moving.

I am having trouble with traction control on my 2021 SX Xline... when turning it comes on suddenly resulting in power loss and no ability to accelerate. This has happened four times since purchasing the vehicle. I nearly got hit when it happened twice last night trying to get home. It is dry here - no water or rain. The vehicle was in smart mode, has awd and the traction control lights flickered on and off on and off right before the problem happens.

The transmission failed entirely after 3,738 miles, disabling the car. Fortunately, the vehicle was parked when the transmission failed. Loss of power while actively driving could result in serious risk, crashes or death. Upon completion of repairs, Kia Van Nuys self-reported to me that at least 4-5 2021 Kia Sorrento were currently in for repair with the same issue of transmission failure after only 3,000 - 4,000 miles.

Rough idle when waiting on intersection due to red light. possible knocking sounds each and every time engine turns off due to stop & go feature or when I turn the key off. It's been happening since middle of March..

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. The crack is topmost more on the driver’s side, initiating a pinpoint exactly on the edge of the middle black patterned grid directly to the left of the rear view mirror mounting. 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. I am concerned about the possibility of a factory defect due to the recall of 2019 Kia Telluride windshields. This car is only 6 months old.

The contact owns a 2021 Kia Sorento. The contact stated that after parking the vehicle, the contact noticed that the exhaust started to leak. The contact also stated that the engine was overheating. The contact stated that there was no warning light illuminated. The vehicle was taken to an independent mechanic but was not yet diagnosed. The vehicle was not repaired. The contact was relating the failure to NHTSA campaign number: 21V519000 (Fuel System, Gasoline). The manufacturer had not been informed of the failure. The failure mileage was approximately 7,911.

KIA's manual gives instructions on two different ways (having two is a bit odd) to disengage their adaptive cruise control (KIA's name for it is Smart Cruise Control). Neither works. 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 next, please realize this has been ongoing since our purchase on April 30, 2021.

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 by another car. I move the shifter into a different gear to see if it would catch and it didn’t. I continue pressing the gas pedal and it all of a sudden lurched forward and started acting like normal. I was about a half mile from home at this point. The car acted like normal and I was watching the dash to see if any warning lights were illuminated, no lights every appeared on the dash. Dealer can't replicate issue.

Purchased vehicle new on 4/7/21 Had an issue on 4/15/21(NHTSA CLAIM# 11408325) - Sons Kia advised that it was just a loose battery terminal cable. Pleaded with them to replace cable for possible short to no avail. On 6/6/21 - the car wouldnt open with key or UVO application - called KIA Roadside Assistance twice and couldnt get anyone. After a couple of hours, the car finally had power and let me in. While driving home, on the interstate, I was going 60 mph. I tried to speed up, but the car wouldnt let me and the RPM stayed at 2(2000). When I got off the exit, I slowed down to turn. When I went to push gas, it didnt want to accelerate. It finally accelerated after a couple tries. Additionally, I noticed when speeding up and slowing down - I hear clicks when the gears change. I dropped the automobile off at Calavan Kia in Lithia Springs, GA. Waiting on a service advisor to call.

ONLY HAD CAR 8 DAYS WITH 500 MILES. WENT TO PULL AWAY FROM STOP SIGN AND CAR CUT OFF. WHEN ATTEMPTED TO RESTART, CAR ADVISED TO PLACE IN PARK FIRST. ONCE PLACED IN PARK AND PRESSED START BUTTON - ALL SYSTEMS WENT DEAD. SPARKS CAME FROM GROUNDING CABLE UNDER HOOD. WHEN GROUNDING CABLE WAS ADJUSTED, CAR STARTED TURNING ON AND OFF RANDOMLY. AFTER WAITING TWO HOURS FOR TOW TRUCK, WAS ABLE TO ADJUST GROUND CABLES WELL ENOUGH TO DRIVE HOME. SUBSENQUENTLY, CAR WAS TOWED TO DEALERSHIP.
