Had engine replaced due to recall and now its doing the same thing as it was before the engine replacement by kia. I was going 65mph with cruise control active on the highway and all of a sudden it slowed me down to 20mph, check engine light blinking and went into limp mode. Will not go over 2000rpm and literally shifts like a standard when it is an automatic. This is such bull on having these issues, and doing the same crap as it did before the engine replacement which was done in March/April. I hope I dont have to keep driving it til it throws a rod like before in order to get it replaced and fixed. Kia is not a safe vehicle. I would like a rental.

In late Feb. 2021 my check engine light came on, as well as my UVO system telling me there was something wrong with my emission's control systems. I immediately stopped & had the code read. P0447 Evaporative Emission system-Vent Control Circuit Open. My husband researched & found there was a wire broken, it was fixed. The check engine light went out for approximately 2 days & in early March, same thing, check engine light, stopped & check the code reading, yep same exact issue. We completed a full tune up on the vehicle, new wires, plugs, everything, fluids. Check engine light went out again & once again 2 days later yep same exact issue as well as it indicating the timing cam sensor was bad. With this new code, I made an appointment to take it to the dealership. 3/28/21 my appt date. Took the vehicle in, was told they would send a video of the inspection (which they did not)via text & they would complete the software update for the knock sensor. When they were done, they came out stating there was slug in my engine & it needed a new engine. They wanted all my oil change records & said they would try to get Kia to pay for it. They charged me 150 for the diagnosis, of which they never showed us any pictures of slug from the engine, nor did they ever really say what was wrong. Now I am doing research & find there was a recall for 2.4L engines and they want to charge me to put in a new engine, when these are the ones that have issues. By the way, they us if we drive it the engine will blow up, well I don't have a choice but to drive a vehicle I am still paying on as I do work. It hasn't blown up yet! Is it possible they thought they had a dummy in their presence and found metal shavings & just didn't tell me. Also when the check engine light came on, it didn't change the driving, other than the vehicle has used about a Quart of oil a month, I have had no other issues. I just want my vehicle fixed!

As soon as I pulled it off the lot within a few months I had some stalling where it would only go 30 mph I was pushing down on the gas full blown and then all of a sudden it would jerk and then it would go again I took it to the dealership the first time in 2016 and I told him that and they said they couldn't help me there was nothing wrong with it so I said okay second time and did it I took it back there and said there's something wrong do some testing they did some testing nothing. I was doing 70 mph and it jerked on me it slowed all the way down to 30mph by it self a semi I just passed I ended up hitting the milepost marker went through four lanes of traffic that semi almost hit me and killed me $10,000 worth of damage to my car I told guys need to figure this out. Kia they said nothing was wrong with it I got the body damage fixed I had full coverage. I went in again and told them there's something wrong with this vehicle they said it was fine so then I drove it for about a year it kept stalling but then it caught on fire smoke started coming out of the engine compartment as I was driving and my gauges went crazy went all the way to hot so I pulled over . I jumped out another person pulled over that was coming the opposite way and yelled get away from the car just in case it blow up it was white smoke at first and then it started turning into black smoke it was burning something had to sit there for hours we called Kia told him to come get it engine had caught on fire. Kia then said theyre replacing engine they did the inspection at no time did they tell me there were any recalls. It took all that for them to finally help me. I bought a new car for a reason I spent over $32,000 for this reliable car I wouldn't take it on a trip it's unsafe my headlights go out all the time I'm sick of buying bulbs so I don't drive at night. I need a new vehicle I got one of the bad seeds kia had yet to say there in the wrong. I am still waiting for them to help 4 years now

Engine failure due to bad rod bearing. Kia will not fix the engine due to a software update not fixed previously. This vehicle was just purchased. A software update will not fix a premature engine failure. The update only turns on the check engine light if the knock sensor detects a knock.

I TOOK IT IN TO GET THE CODE READ, AND WAS GIVEN A CODE INDICATING THE TIMING CAM WAS OFF. ONCE I GETS TOOK IT INTO THE DEALERSHIP IT WAS DETERMINED I NEEDED A NEW ENGINE DUE TO METAL SHAVINGS FOUND IN MY OIL FILTER AND PAN. THE OIL WAS ALSO NOTED TO BE VERY LOW, DESPITE ME HAVING PERFORMED THE OIL CHANGES AT PROPER INTERVALS. I SINCE HAVE LEARNED ABOUT THE ENGINE RECALLS FOR THE SAME YEAR, BUT IN THE SMALLER 4 CYLINDER 2.0 AND 2.4L ENGINES. UPON LEARNING ABOUT THIS AND LOOKING FURTHER INTO IT, I HAD READ THAT ON SEVERAL CONSUMER WEBSITES THAT OTHERS WITH THE SAME YEAR AND LARGER 3.3L V6 ENGINE AS MINE WERE HAVING THE SAME ISSUE OF ENGINE FAILURE DUE TO METAL SHAVINGS FOUND DESPITE ALSO PERFORMING PROPER MAINTENANCE OF THE VEHICLE. SO MY ISSUE IS NOW I NEED A MEW ENGINE AS HAVE OTHERS, BUT IT IS NOT RECOGNIZED AS PART OF THE ISSUE WITH THE SMALLER ENGINE 2015 SORENTO'S.

AFTER MY 2015 KIA SORENTO SX WAS RECALLED FOR FAULTY ENGINE; IT WAS REBUILT. HOWEVER, MY CAR HAS RECENTLY STALLED WHILE DRIVING AND I HAD TO GET IT TOWED TO THE DEALERSHIP. I WAS TOLD THERE WAS ANOTHER ENGINE OIL LEAK. THEY CLAIMED TO REBUILD THE ENGINE, BUT I AM HAVING THE SAME EXACT ISSUE. I HAVE HAD NOTHING BUT ISSUES SINCE PURCHASING THIS CAR. THIS IS A VERY DANGEROUS PROBLEM, AND COULD HAVE RESULTED IN A FIRE CAUSING SERIOUS BODILY HARM OR WORSE. I AM ASKING FOR ANOTHER RECALL, BECAUSE APPARENTLY THE FIRST TIME THEY ALLEGEDLY FIXED THE FAULTY ENGINE WAS TO NO AVAIL AS I AM HAVING THE EXACT SAME ISSUE AS I HAD PRIOR TO THE ENGINE BEING REBUILT. THE PROBLEM HAS NOT BEEN REMEDIED. I ALSO READ SEVERAL NEWS ARTICLES WHERE THERE WAS RECENT RECALL ON THE KIA SORENTO MODELS AS WELL AS SEVERAL OTHERS. HOWEVER, UPON SEARCHING TO CHECK IF THERE WAS IN FACT ANOTHER RECALL, THERE IS NOT. THIS IS CONFUSING AND I WOULD LIKE TO KNOW WHAT IS GOING ON AS SEVERAL NEWS ARTICLES STATE INDEED 2015 KIA SORENTO HAS ANOTHER RECALL.

DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:oil/lubrication:pressure/temperature Sensor
In a letter dated September 30, 2021, Mr. Gerald James (the petitioner) requested that NHTSA conduct an investigation of the Model Year (MY) 2015-2017 Kia Sorento equipped with 3.3L V6 ?Lambda? engines for ?severe oil leaks? from the oil pressure switch (OPS) that could ?lead to engine failure? with little warning to the driver. Mr. James based this request on his own experience and data found in NHTSA?s Vehicle Owner Questionnaire (VOQ) database. NHTSA reviewed the material cited by the petitioner, information submitted by Kia, NHTSA?s testing, and other pertinent information in NHTSA databases.On November 12, 2021, ODI opened Defect Petition DP21-002 to evaluate the petitioner?s request. ODI performed an analysis that included evaluation of the petitioner?s vehicle, searches of ODI complaints from vehicle owners, non-dealer field reports, manufacturers? supplemental information relating to design of the component, and component testing performed by ODI.On December 16, 2021, ODI and Kia North America performed a joint inspection on the petitioner?s vehicle. ODI and Kia agreed the OPS was leaking oil and observed oil in the crevices atop the engine block. The vehicle received a new replacement OPS and was delivered back to the petitioner. The original part that was removed from the subject vehicle was retained by ODI for further analysis.As of December 30, 2022, for the MY 2015-2017 Kia Sorento population of 161,519 vehicles with 3.3L engine, NHTSA reviewed internal data and has identified no consumer complaints or field reports in its database, with unique Vehicle Identification Numbers (VIN), citing engine failure or stalling related to the petition?s allegation of defective OPS. When combined with the supplemental warranty and technical analysis from the manufacturer, field report and customer complaint data in response to the Information Request letter sent, NHTSA identified no unique VINs alleging engine failure or stalls caused by OPS leaking on the subject vehicles named in the petition.On April 4, 2022, the Vehicle Research and Test Center (VRTC) performed testing of the petitioner?s component (OPS) based on testing protocol consistent with Kia?s specifications for the subject vehicle. The testing involved the petitioner?s original OPS in a controlled system to replicate the subject vehicle?s oil pressure, flow, and temperature. VRTC determined that a vehicle would have to miss more than a dozen oil change intervals to reach low engine oil capacity. Testing also revealed the OPS would operate, as manufacturer intended, illuminating the vehicle?s MIL to alert the driver of lower oil pressure.In April of 2022, Kia North America issued a warranty extension that extended the coverage of the Oil Pressure Switch from 5 years/60,000 miles to 15 years/150,000 miles on MY 2014-2018 Sorento, MY 2014-2016 Cadenza, and MY 2015-2018 Sedona vehicles, all equipped with the 3.3L Lambda engine. The extended warranty coverage includes diagnosis, repair, and applies to customers experiencing engine oil leaking from the engine or if the engine oil pressure warning light stays illuminated after the engine is turned on.After a thorough review of the material submitted by the petitioner, information already in NHTSA's possession, testing performed by VRTC, technical information provided by Kia, the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that an engine failure due to the alleged defect is likely and does not warrant a formal investigation.

The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.
