10/2021 Drove to store (about 20 minutes). Shopped for about 1 hour. Started to leave parking area and enter ramp to highway when the engine stopped. Everything went off. No warning. No check engine light, no maintenance light, nothing. I was able to steer back into the parking area. Put car in park and waited about 4-5 minutes. Started the car (it started without a problem) and began driving in the parking lot. when it began hesitating and feeling as if it would stall again. there was a gas station next to the parking area. pulled in & filled tank (tank was 1/2 full) and just barely pulled into a parking spot in front of gas station convenience store. Got towed to our local garage. They changed the oil and checked external systems and thought it was working fine. When my husband picked the car up it was still hesitating and almost stalling on the way home. Next, took it to local Kia dealer. Same situation. Couldn't find anything, said it drove fine for them. Same thing happened to my husband on the way home. Stalling in traffic. Having to restart the car in an intersection. Very dangerous. Brought back to dealer and they said it would cost $600-1000 to diagnose. Then it might cost $5000 - $10,000 to fix (replace or rebuild the engine). I reached out to Kia Customer Service but they did not offer any solutions other than to talk to the dealership in question. We are at a stand-still and have not been able to drive the car since October 2021.

My 2015 sorento (original owner) just flat out died while driving in the left passing lane on interstate 85n from the airport in atlanta (in the pouring rain 6/8/2019) and without any warning. Not only did it just stop running "everything died" no lights, no hazards; no power windows etc. It would not even acknowledge the key fob. The SUV was completely dead. I was so lucky to not have been hit by another vehicle. Once the hero truck pushed me across 8 lanes to safety; I had to have my SUV towed to the dealer. The diagnosis: 'the alternator and battery were both bad and had to be replaced for 1500.00'. What?? Of course, the warranty had just expired the month before; mileage just had turned 50k. I was completely shocked as no indicators of anything going bad occurred. No warning lights; no hesitation starting; no dimming lights, no noise; etc.' it had full power; everything was normal! My SUV had 'every maintenance' performed on time and was still 2k away from its next service. This incident not only placed me in a very dangerous situation it troubles me greatly there was no warning at all. Again, no indicator or symptom of anything wrong. This SUV is my 2nd sorento and will be my last kia. I do not feel safe in this brand of vehicle. I want to add my first sorrento; (2008 ex model, I can supply a VIN too) also had a major repair event occur right after its warranty expired (within 2 months); the rear differential went bad and had to be replaced. I really wonder if this is a trend with kia; major issues occuring rsoon after warranty expires; major repairs/costs are the result; not to mention the issue placing you in a dangerous situation without warning. Something is wrong here. I have never experienced this with any other vehicle I have owned right neither right after a warranty expires or even close after and when I do? Both were sorrento's

My 2015 kia sorento has metal flakes in the engine, burns 2 quarts of oil every 2ooo miles, it hesitates on acceleration, white exhaust smoke, burns a lot of gas, the engine check light and uvo warnings constantly turns on, it can catch on fire anytime, the engine can lock anytime. We need more kia recalls before lives are lost.

While driving approximately 50mph in my sorrento the car hesitated and stalled when I pressed the gas to pass a car next to me. Ithe felt like a slip. I wasn't sure what to make of it, but over the next 4 days it started happening more frequently. I went to turn it on the 4th morning and a cloud of white smoke came out of my tailpipe. I decided it needed to go to kia immediately. My sorrento is a 2015 with 27xxx miles on it. This is not what I expected from a new car. I brought it to kia and was called 10 minutes after I received my courtesy ride back. I was told a diagnosis was sludge and they needed maintenence records. I brought my receipts (which I had to have my mechanic type back out as I hadn't saved any reciepts). When we brought those in I had a spare key to my car and noticed it was in the parking lot. I checked under the hood only to discover they hadn't even pulled the valve cover on the car (I know this because there was a dead wasp frozen to the top of the bolt you need to take off to remove the cover that was there when I brought it in). They informed me that they opened the cap and that's how they knew even though initially on the phone they said they pulled the valve cover. They took my service papers and called me the next day to say kia won't cover it and rejected my records. My mechanic is a licensed mechanic. No reason given for the rejection. They say we will be responsible for engine replacement but still can't give us a diagnosis other than "sludge". So much for their "best warranty in the business".
