What owners say about the fuel/propulsion system

Verbatim from NHTSA complaints, newest first
“Vehicle caught on fire when driving, putting my mother's life and her passenger at risk. My mother is an elderly Deaf woman, but was able to pull over in time for Fire Department to help contain fire. There were no warning lamps or messages of any problems with car, the car started smoking (smoke also entered cabin) and they pulled over where there was a fire under hood and bystander call emergency services. The car is currently at a tow lot and should be available for inspection upon request. We are waiting for car to be inspected by insurance.”

“I took my 2016 Kia Sorento to the dealership for an emissions service update as a result of a service bulliten (SC340) After recieving the car back, the transmission acts unpredictably and the throttle is erratic. This happens when started cold and continues until the engine reaches temperature. It did not do this previous to the update. It is a safetey hazard and almost caused a collision. The throttle response was sluggish, it hunted for gears and as a result I was unable to safely merge into traffic endangering myself and other drivers.”

“(Transmission and motor) I had taken my car to the dealership on XXX for recalls and all the signal were fine before going there. They took my car back to do the recalls and my son and I waited . Once they were done we left closer to closing time is noticed there was a burn mark on my dash board that wasn’t there before the recalls. Going forward on the way home. We were waved down by a man stating that my signal and brake light weren’t working . So that next day we took my car back to the dealership to see what happen, why all the sudden different alerts were coming up. They had the same mechanic relook at the car and a when finish 31/2 hour latter was told I needed a new transmission, costing $7384.94 which I don’t have . They charge me $179.00 just to confirm what they said about needing a new transmission. I was devastated and confused why I wasn’t told that the day before. So a few days later I took it to another machanic to see if the could see why the lights weren’t working and he ended up putting new bulbs in and got them working but also he put it in a diagnosis machine 2 of them and couldn’t get a reading at all and said I should take it back to find…”

“Car completely stalled while on the freeway with no warning, no engine lights, nothing….luckily we were going downhill and were able to pull over to the side safely. Still owe 6k to the finance company but mechanic claimed I needed a new waterpump…after being changed and charged the car still wouldn’t turn on despite the new waterpump….and a bunch of new obd codes showed up & now I need a new engine. After a lot of research I’ve learned this car is notoriously known for many recalls and overall complains…..I wish I had done research before buying it, now I’m in debt for a car I can’t even drive”

“The vehicle is a 2016 Kia Sorento equipped with a 2.0L Turbo Theta II engine subject to the KSDS (Knock Sensor Detection System) safety recall. The original engine was replaced at approximately 70,000 miles under Kia’s engine service program. The replacement engine currently has approximately 32,000 miles. The vehicle developed internal engine damage diagnosed by a Kia dealership as a burnt exhaust valve. A burnt exhaust valve indicates abnormal combustion conditions such as lean operation, pre-ignition, detonation, timing deviation, injector malfunction, or lubrication failure. These are conditions the KSDS recall was intended to detect and mitigate. Kia Consumer Affairs denied warranty coverage, stating that the extended warranty applies only to rod bearing failure and that no further escalation would be pursued. Kia Consumer Affairs declined to escalate the matter for District Parts & Service Manager review and directed the owner back to the dealership. During the prior engine replacement, the dipstick was observed to be glued in place, raising concerns regarding oil level accuracy and lubrication integrity on the replacement engine. This complaint is…”
