Our 2021 Kia SORENTO has been to Elmhurst kia service numerous times . The chief complaint is the Kia Sorrento keeps losing power while in drive reverse middle traffic even on the highway but yeah every time we take it in, they say either it’s the battery .you can’t use it in the Eco mode .turn off the shut off while in drive mode when at stops ! always a different excuse, but yet no recall and it’s not showing up on their computer, but yeah it’s happening and Kia does not want to take ownership. The vehicle has been left there for numerous weeks at a time leaving us without a vehicle no loaner . But because cannot duplicate issue release vehicle back with no repairs or maintenance. Kia prefer you taking the car getting into a car accident before they decide to do anything or even a lawsuit because not enough people having same issue with the 2021 kia SORENTO s model ! If you also have these issues please report them here so they can be forced to open a recall !!! Before someone gets seriously hurt my SORENTO has loss power on highway and in the middle of train tracks with my little ones in SORENTO and we drove the vehicle from day one original owners not a used SORENTO
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 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.
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.
I'VE HAD VEHICLE FOR APPROXIMATELY TWO MONTHS AND TWO DAYS. INTERMITTENT ISSUE WHERE VEHICLE FAILS TO ACCELERATE WHEN MAKING A TURN AFTER STOPPING (NO VEHICLE IN FRONT) OR ACCELERATING FORWARD AFTER A STOP (STOP LIGHT WITH VEHICLE IN FRONT). ISSUE OCCURRED FIRST ON 20 FEB 21 AND AGAIN ON 23 MAR 23. VEHICLE WAS PURCHASED 23 JAN 21. ISSUE SO FAR APPEARS TO OCCUR MONTHLY AROUND THE SAME TIME OF THE MONTH. ISSUE NOT EASY TO REPLICATE. CONCERNED THAT ISSUE COULD CAUSE AN ACCIDENT AS VEHICLE LITERALLY ACCELERATES ABOUT 1-2MPH AND WHEN OUT OF "DANGER ZONE" ACCELERATION PICKS UP. VERY SCARY. REFER TO THIS FORUM THREAD - IT APPEARS A COUPLE OTHER PEOPLE MAY BE HAVING A SIMILAR ISSUE. HTTPS://WWW.KIA-FORUMS.COM/THREADS/SPORADIC-ISSUE-NO-ACCELERATION-FROM-STOP.350565/
