Owner reports
Selected complaints filed with NHTSA by 2014 Kia Sorento owners, lightly cleaned up (personal details are redacted by NHTSA).
The car engine started on fire while I was driving after all the recalls were fixed and new engine installed. The car was completely destroyed the whole engine compartment was completely burned. Kia says it was an oil leak but that's not true the car oil change was done regularly and was serviced within 3 months of the engine fire. I also had this vehicle parked inside my garage for 5 years and not a single drop of oil in the garage floor. Kia is also refusing to send me a full report of their findings from the fire inspection. Kia adjuster is acting in bad faith by not providing the fire report. The car engine was replaced new due to an earlier recall and within 10,000 miles the new engine caught fire. They don't want to be liable for this engine fire but cars don't just burn without any reason. …

During a moderate T-bone collision at the driver rear side quarter panel, the back seat of the vehicle almost immediately was in flame, injuring all three occupants, not fatally, fire originated underneath the rear seat near the refueling port, which had the cap in place.
I was driving on the high way and took an exit. I started to smell something from my car so I turned it off at a stop light. I looked briefly at the dash but no lights where on. Then I saw smoke coming from the hood of my car. So I put my emergency flashers on and got out within seconds of getting out the smoke turned to flames so I called 911. Entire front of my car was in flames and a couple small explosions happend I believe the first one was the air bags but the second sent my hood flying upwards. My entire inside of the car was chard by the time the fire rescue showed up. There was a line of traffic behind me that stretched close to a mile since it was during traffic night. I didn't have enough time to pull the car over safely without the risks of being inside the car while it had fully ignited. The fire men had to get people and cars away from my car. …

Kia Corporate Complaint No. [redacted] We bought a used but Kia certified 2014 Kia Sorento with 29K mileage in Jul 2017. Ran great but check engine light came on 3 times. Well before 100K mileage, we took it to dealer service department and we're advised it was an 'electrical problem' that reported a false code. Each time the check engine light was reset. Car ran great except for the false trouble lights. We were told that if the light did not blink, not really a problem. At 120K mileage, we got a code and took car to local garage. Mechanic changed 6 plugs but advised that No. 6 coil may need to be replaced. At 122K miles, 3 weeks ago, we got a solid check engine light but with a serious female voice and pop up screen advising we get to Kia dealer. This time code was run by our local mechanic for clogged catalytic converter. …
While driving car it suddenly lost acceleration. RMP's wouldn't go above 1.5. Speed wouldn't go above 20MPH. Check engine light came on. Was going up a hill with lots of cars behind me and suddenly could barely move. Made it to an Advance Auto and they ran diagnosis on the check engine light and it came up with 2 different codes, relating to fuel system and crankshaft. When I got the vehicle to my local mechanic they saw the codes also, and that the car had gone through 4 quarts of oil. I wasn't at the mileage for an oil change yet, so not sure why oil was almost gone. Mechanic did and oil change and issue was still not fixed. Stating engine needs to be replaced. I have several other people with Kia's who have also recently expirenced massive oil consumption and engine dying. Car was running fine prior to just going into "limp" mode randomly. …
I was driving and my car started acting like it was stalling out. I pulled over and put it in park and turned off the engine. I tried to restart, didnt restart. Let it sit a minute, and tried to restart again, it did. I drove straight back home about 2 miles away and didn't drive it further. There were no indicator lights on, so we had no idea what had just happened. My husband checked the oil, everything was ok. Drove it a few days later, was driving around just fine for about 30 minutes, then the same thing happened, I heard a clanking/stalling noise coming from the engine, and it was stalling out. Thankfully, I was able to pull over to a residential street and had to get it towed to my mechanic. Again, NO senor lights were on. My mechanic looked at it, and was baffled, because he said basically my engine is shot. …
I experienced a deceleration when I stepped on the gas pedal to accelerate on the interstate. I was going 65mph at the time. The emission control warning light came on so I pulled off the next exit and called the Kia dealer. I turned around and headed back to take it in for diagnostic service and repair when it started making noises so I pulled off onto an exit and the engine stopped shortly afterwards. I could turn the engine on but it would not go so I called AAA to have it towed to the dealer. The steering was difficult as well. The dealer said the engine needed to be replaced and the clock spring needed to be replaced (air bag warning light was on). This experience was dangerous and I was fortunate not to be in heavy traffic and in an area where there was a safe enough place to pull over. The car had 132,000 mi on it. …
