Kia Sorento knocking problems

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 the federal safety agency 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 the federal safety agency investigation into unsafe recall compliance and systemic powertrain installation failures originating from the engine replacement.

October 27, 2026 while accelerating onto a major highway my hybrid SUV would not accelerate beyond 25-30 mph. Several trucks came up on me very quickly!! I pulled over and shut down the vehicle. I started it again and proceeded back on the highway, but still could not accelerate beyond 25-30. Once again, I felt I was at risk. I managed to get home (approx 3 miles) by driving at 30 mph with my 4 way flashers on. No check engine light came on, but I thought I heard a thumping or knocking under the hood. I had the vehicle towed to Fred Beans Kia Mechanicsburg, PA. They could not find anything wrong and are returning the vehicle as is. I have a complaint in with the service manager and am quite concerned.

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."

The car is running rough, losing power and knocking. Unable to drive it safely. The more you accelerate the less power it has. It has been sitting ever since the incident.

My car's check engine just started flashing and the ECU has reduced my drivability to limp mode stating that my knock sensors are showing up on scan test and camshaft position exhaust sensor. When I removed the camshaft exhaust vvt sensor it indeed had metal shavings on it. A have a P1326 and a p0014 code which is basically telling me that my engine is having issue within the internal engine and oil consumption.

1) The engine control system / KSDS knock sensor system triggered safety recall code P1326, accompanied by a flashing check engine light. The vehicle and components are currently at the dealership available for inspection under RO #148484 (Issued on October 2) 2) A flashing check engine light and active P1326 code indicate a potential severe engine failure or severe misfire risk while driving, forcing the vehicle to lose power and rendering it unsafe for operation on public roads. 3) Yes, the vehicle was towed to an authorized Kia dealership on September 24th; however, the dealer initially refused to generate a Repair Order or diagnose the safety recall for over a week until corporate intervention forced RO #148484 to open on October 2nd. It is currently awaiting diagnostic testing. 4) No. It has only been towed to the authorized dealer facility where it awaits initial diagnostic testing under the active safety recall. 5) Yes. A flashing check engine light and code P1326 appeared immediately prior to towing the vehicle to the dealership on September 24th.

Driving down the road and all of a sudden the red oil pressure light appeared then the engine light appeared. The car engine power then reduced and ultimately ended up stopping, turning the car off. The car now has a loud ticking and knock coming from engine. From previous recalls i see that this is a common problem on these cars. This was without warning and occured a couple of days after a oil change. Oil was in good condition and full. The car is drivable but not safe to do so. There's a loud rattling noise while accelarating. Leads me to believe possible lifters and rod knock.

Yesterday our car was making a knocking noise. It lost power temporarily. Upon pressing the gas pedal to the floor we were able to get up to 30 mph. We made it to a repair shop. They looked at it today. The Dip stick showed no oil. The did an oil change and it was down 3 quarts of oil. We just had the oil changed 3 months ago on June 20. No check engine light came on. No warning at all . We were driving on a road with no shoulder, so this was dangerous if the engine were to fail before we got to repair shop. They said we need a new engine and it will cost just under $10,000. It seems that many people are having this exact same problem.

Upon a catastrophic engine failure Tasca Kia replaced engine under Theta II settlement. I picked up my kia on 9/12. Engine is not running properly. It’s jerking and there is loud mechanical knocking. I don’t feel safe driving. I’ve contacted Kia corporate beginning 9/16 who contacted Tasca to arrange for tow and loaner. They said Tasca service mgr would contact soon to set up. They never did. I called corporate again later that day and after they called Tasca they were told service mgr went home for the day. As of this date Tasca Kia has not contacted me. I again called Kia corporate 9/17 asking to please escalate and allow me to use another service dept. The only other service location with loaner is a half hour away and I cannot afford another tow or another rental. I am stranded with a car that is not safe due to installation failure or another defective engine. No one from Kia will help in a reasonable time frame. I’m now told it can take up to 48 BUSINESS HOURS for any assistance. In the meantime I’m being forced to decide on whether to risk driving an unsafe vehicle to the service dept or to continue waiting for Kia to contact me.

I am filing this complaint regarding my 2019 Kia Sorento and an engine failure related to Kia’s Product Improvement Campaign/KSDS (Knock Sensor Detection System) campaign. I purchased this vehicle used in 2022. Prior to the engine failure, I was never notified of any Product Improvement Campaign affecting my vehicle. Had I been notified, I would have immediately taken the vehicle to an authorized Kia dealership to have the campaign completed. My engine subsequently failed, and Kia denied coverage, stating that the Product Improvement Campaign was not completed before the engine failure occurred. Kia stated that notices were mailed to affected owners, but they have not provided me with documentation showing when my specific notice(s) were mailed, what address they were sent to, or proof that I was properly notified. I am concerned that affected owners may not be receiving adequate notification of this engine-related issue before a failure occurs. An engine failure can create a serious safety concern, especially if it occurs while driving, and owners may unknowingly continue operating vehicles affected by this condition without having the opportunity to complete the required update. I am requesting that the federal safety agency review this matter to determine whether Kia’s notification process for this campaign was effective and whether additional investigation is needed regarding engine failures associated with this issue. Vehicle Information: Year: 2019 Make: Kia Model: Sorento Date of engine failure: June 2026 I have documentation from Kia Customer Care regarding their denial of coverage and their statement that the campaign was not completed prior to engine failure.
