Latest Sorento engine complaints
My radiator had to be replaced because a rock flew in and punctured it. After speaking with my insurance adjuster, they made me aware that there isn't any real protection for the radiator or ac compressor. I went online and I noticed that this is an ongoing problem with KIA. I didn't receive any warning lights about low coolant or anything. If this happen to someone else, and they don't notice the leak their engine could overheat. Most people said they have installed a mesh barrier themselves to protect the radiator. KIAs warranty does not cover it because it's seen as an incidental when really it is a design flaw. My car is a 2026, it's insane to have to replace the radiator already.
i havent had a engine failure yet. but i have had an ongoing engine issue that has yet to be found. i have been experiencing clunking/pinging sound from the engine. can not pin point where the issues is coming from. everytime i rev it or even at idle. it makes the sound. when i rev it its very noticable. i took it to the dealership for a diagnosis and they couldnt replicate it. but once the car had been warmed up to operating temp with a fair amount of load on it, it started to make the sound. young kia in layton,...

UT said they can hear it but they cant do anything about it since their is no engine codes they told me that since these kind of cars are sensitive and smart enough it will throw a code oncer the car detects it. but nothing. i then took it to master auto tech in downtown salt lake city, UT, they said they can hear it but can not find the issue. since i have at 98,800 or so miles and im at the near end of the warranty, i am very concerned that worse case scenario that i will have a even bigger issue.
Vehicle caught on fire under neath while driving
Severe high-pressure fuel system failure and engine oil fuel dilution creating a fire hazard and engine seizure risk following a corporate engine replacement. On July 15, 2026, my 2016 Kia Sorento (2.4L GDI) received a corporate-covered engine block replacement due to rod bearing failure. On September 30, 2026 (2,332 miles later), the vehicle jerked violently while driving. Inspection revealed the engine oil was heavily diluted with gasoline due to an internal failure of the High-Pressure Fuel Pump (HPFP), creating...

a fire hazard. The HPFP was replaced out-of-pocket. Kia Corporate Case #26456059 is open regarding this safety issue. A severe safety hazard currently persists. Within 20 days and 176 miles of this fuel pump repair (totaling 2,512 miles on the new block), the vehicle exhibits severe drivability issues and the oil dipstick again smells heavily of gasoline. This fuel dilution compromises oil viscosity, threatening catastrophic engine seizure and creating an active fire hazard. Due to the severity of this fire risk, the Kia Executive Director of Customer Care intervened, ordering an emergency flatbed tow to a different authorized facility. An invoice audit revealed the dealer violated Kia repair protocols, factory TSBs, and federal safety guidelines. Kia's factory TSB mandates that the high-pressure fuel pipe is a strict, single-use component that must be replaced upon pump removal; however, this part was completely omitted from my invoice, confirming it was dangerously reused. Reusing it introduces a volatile engine-bay fuel leak risk, mirroring the hazardous pattern in NHTSA Recall 18V-907 (Kia Campaign SC172) regarding fuel lines mishandled during engine swaps. Furthermore, the dealer illegally charged retail fees for Service Campaign SC340 materials and withheld all diagnostic trouble codes (DTCs). I request a formal NHTSA investigation into unsafe recall compliance and systemic powertrain installation failures originating from the engine replacement.
While making a right hand turn at an intersection, the engine shut off and I was able to drift into a parking lot - the entire dash board lite up different indicators. Turned off ignition, waited about 15 minutes and attempted to start; however, immediately upon starting the engine started to run rough so immediately shut it back off. Had towed to a service repair shop who has informed me that the vehicle is in need of a long block remove and replace.
I read about some 2019 Kia Serento with V 6 engine have recall for leaking oil sensor. Yet when I look up my vin it is not listed ? Looking for any recourse for why some vin numbers are not covered when this is a problem ??
1. Headlight Failure (Recall Malfunction): Last year, my headlights began intermittently shutting completely off while driving at night, creating an immediate visibility hazard. Kia of Palmdale performed the designated recall repair, but the dangerous defect remains. The headlights still shut off unexpectedly while the vehicle is in motion. 2. Shift Lock Failure: In May 2024, just two months after purchasing the vehicle, the shift lock mechanism failed completely. This intermittently prevented the vehicle from...

shifting properly out of park, creating an entrapment and stalling hazard. 3. Catastrophic Engine Failure: Last week, the 3.3L V6 engine suffered a sudden, catastrophic mechanical failure while driving. This caused an immediate loss of motive power, putting me and other drivers in severe danger.

My Car started to have extreme oil consumption around 100,000 miles I was able to keep it maintained by adding oil frequently but finally part of my motor stopped functioning and I was forced to replace my motor. I got my car back June 22,2026 but the new motor also has had the same issue. I did purchase a warranty for 3 years but unfortunately it only covers one replacement. This motor did not even last 6 months.
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.
The engine failed due to a manufacturing defect that is well known in the company but they aren't calling it a recall, they are calling it an improvement and therefore my car isn't qualifying and isn't being repaired
My check engine light came on. I took my vehicle to AutoZone so that they could tell me what the code read. The code read, cylinder 2 and cylinder 3 misfire. I replaced all 4 cylinders and spark plugs. 6 months after replacing all the parts, I had the check in light come on (flashing) while driving out of town. I was able to drive the vehicle back to town and after the vehicle sat majority of the day, it cleared on its own. Almost a year to the original date, I had my check engine light come back on. I took my vehicle back to AutoZone and the code read, cylinder 3 misfire. They were able to clear the code but it came back on within 30 seconds.
I bought a used 2020 Kia Sorento LX 2.4L in 2022. It had 15,000 miles on it. AT 50,000 miles I noticed it was consuming oil. I have been changing the oil at 5,000 mile intervals even though the manual calls out to do it every 7,500 miles. I have records of the maintenance for every oil change done on this vehicle. I kept a log and now at 54,740 miles it is consuming 1 quart every 500 miles or so. I took it to the dealer on 10/19/2026 and was told that since I was not the original owner there was no warranty...

coverage on it. So that nullified the 10 year/100,000 mile warranty. I was told they could do a chamber cleaning for $800.00 and if that failed I would need to replace the engine at an out of pocket cost to me of $9,000.00 to $10,000.00 I have to monitor the oil level constantly to avoid the engine seizing and breaking down in traffic . This auto is used by my spouse to drive my grand kids to and from school. There are no warnings or messages on the oil level so it is driven with uncertainty .

I am the original owner of a 2016 Kia Sorento and have lived at my original registration address since purchasing the vehicle. The engine suddenly and catastrophically failed/seized due to internal rod bearing failure. The local Kia dealership is denying the recall engine replacement because the KSDS (Knock Sensor Detection System) software update was not performed. However, Kia America failed to mail me a statutory recall notice to my verified address. The dealership is weaponizing Kia's own notification failure to deny coverage for an acknowledged safety defect."
