2016 Kia Sorento Fuel system Problems

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 out why he couldn’t get a reading. I was so frustrated at that point I just was upset! I then had a friend of the family mechanic look at it and he said it wasn’t the transmission it was a knock sensor that I needed so I ordered it. When I called him to install the knock sensor he was too busy to do it and it had already been a whole month of waiting so I reached out to a place in Cumberland RI to see if he could install the knock sensor had it towed there and he kept it for three days and said it was a transmission computer and he tried two of them and neither of them worked and charged me $150 for that I was humiliated and crying , I went there to have my car towed home seen him while waiting for the tow truck to come he said I needed a new transmission and now a motor, crying again.

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

Incident

Feb 27, 2026

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 submitted due to concern that a KSDS safety recall-related engine failure involving abnormal combustion was not properly reviewed or escalated, and that recall procedures were not administered in accordance with their intent.

The safety hazard began with a pattern of ignored warnings by the authorized dealer network. On Aug 15, 2025, I brought the vehicle to Luther Kia of Bloomington for a Check Engine Light. The dealer simply cleared the code without diagnosis, failing to catch early signs of engine trouble. On Sept 22, 2025, the engine failed again. I drove the vehicle in unsafe "limp mode" to Luther Nissan Kia [XXX] ). They found the engine was "4 quarts low on oil" (severe starvation just 37 days after a dealer oil change). Despite this catastrophic finding, they failed to diagnose the root cause and released the unsafe vehicle to me after selling only a spark plug replacement. On Sept 26, when I attempted to pick up the vehicle, the Check Engine Light was flashing immediately at handover. I refused to take the unsafe vehicle. The dealer then replaced an Oil Control Valve (OCV) and released the vehicle to me again later that day. After this second "repair," I drove the vehicle for only a few miles before the engine failed again with a Check Engine Light. The dealer has since admitted in writing (BBB complaint #XXX) that the engine was "deprived of lubrication" due to the initial low oil condition. By ignoring early warnings and releasing a vehicle with a dying engine twice, the dealer put me and other motorists at risk of a sudden loss of power at highway speeds.

Vehicle: 2016 Kia Sorento, VIN [XXX] Incident Date: November 13, 2025 Incident Location: Durham, NC (3828 Guess Rd) Cause of Loss: Engine Fire, confirmed by Durham Fire Department Report (Incident #253663) as "originated from under the hood." TECHNICAL NARRATIVE & SYMPTOMS (CRITICAL FOR LIABILITY): I am filing this complaint to report a catastrophic vehicle fire that I believe is directly linked to multiple acknowledged manufacturing defects that create a fire risk in Kia vehicles. ABS/Traction Control Light Warning (Direct Fire Risk Symptom): Immediately prior to the loss, the ABS and Traction Control warning lights were constantly illuminated. This is a known precursor symptom for the defective Hydraulic Electronic Control Unit (HECU) or ABS Module short-circuit, which has been cited in numerous Kia fire recalls (e.g., NHTSA 20V019, 20V519). The fire's origin under the hood is consistent with this component failure. Prior Engine Failures (Systemic Defect History): This vehicle has a history of catastrophic manufacturing defects: The engine assembly was replaced in 2023 due to the known Theta II Rod Bearing Failure. The knock sensor was replaced in September 2025 as part of the KSDS Product Improvement Campaign, demonstrating the vehicle was still under active service for critical engine monitoring defects just weeks before the fire. Potential Tow Hitch Wiring Fire Risk: The vehicle was fully engulfed, but the fire may also be linked to the defect cited in NHTSA Recall 22V703 (tow hitch wiring harness short circuit, which also poses a fire risk). I require a full investigation into this defect leading to compensation for the total loss of the vehicle and consequential damages.

Kia stated that the high-pressure fuel pump had went bad from the time I left the dealership and got home. I paid over $1,350 to replace a High-Pressure Fuel Pump. On the way home engine light and loss of power. I returned to Kia. They stated that gas had gotten into my oil. They changed the oil and I headed home, same issue engine light and loss of power. I told Kia of Johnson City I wanted a refund, and they could put the old part back on. Kia of Johnson City told me to take the car to another dealership that I was not getting a refund, and they would not fix my car. The engine codes and problems were the same as when I picked the car up from Kia. I have tried twice to have Kia of North America buy the car back due to it not being fixed and I do not feel safe in the car. I have taken the car to a Hyundai dealership in Johnson City Tn. and asked them to check the engine code and loss of power. Another $223.05. They stated the high-pressure fuel pump was defective.

1) I bought this car in October 2021, when it had ~79,000 miles on it. After ~2,000 miles, it showed a low engine oil sign, and it has been showing this issue since then, i.e., I have to change my oil/filter after every ~2000 miles. It has incurred a huge cost. I talked to the dealers, but they did nothing to solve this problem and charged me ~$1200. Funny part. Whenever I go for an oil change, they say that KIA/HYUNDAI cars have this engine problem. It's a joke to this system that the Govt still allows them to roll on the USA roads. 2) Today, this car had a flashing engine light. I will go to a mechanic tomorrow, but afraid of how much they will charge.

Unknown component or system failed. My car suddenly stalled while on the highway, not allowing me to increase speed (over 40 mpg) and then stopped. I was scared to death when that happened on the highway as we could have been hit by other vehicles. I was able to restart it but it kept doing it, gradually reducing my speed to 20mpg then a lamp warning sign appeared. The car only has 50,000 miles on it and no warning light or prior failure before this happened on 11/29/2024. I took it to Kia for inspection and they told me if the engine will have to be replaced, it will take 3 months. They took my car in for inspection and I am now 10 days without a car and I have not yet heard from Kia.

While driving on the parkway, the vehicle would not accelerate and would stall. After pulling over, vehicle would restart but repeated the pattern. Made it to Advanced Auto who ran codes and had the camshaft modulator changed. Vehicle made it back onto parkway. 40 miles from home, the vehicle began to shake, loose power, made loud sound and died. Towed home. Mechanic said out of oil but I had oil changed less than 1000 miles ago when vehicle purchased. New codes showed crankshaft position sensor. Changed part. Replaced starter and a new battery. Still nothing. Stating probable engine failure. I've only owned this vehicle for 2 months!
