My vehicle was stuck in park. I noted that module 2 fuse was blown. I replaced the fuse and smelled smoke. I took my Sorento in to the local KIA dealership for diagnosis. It was determined by a technician that the headlight level sensor and harness pigtail were both significantly melted. It was suggested by the tech to remove the level sensor and that has created a safety issue with the headlights pointing significantly low. The level sensor or headlight leveling system and harness connection are a potential fire hazard and if the component fails, this creates an additional unsafe driving condition with the headlights aiming low.

Snow Pearl White paint is chipping at various areas of the front portion of the vehicle. I was driving in heavy rain and then noticed a huge chunk just chipped off. Several owners with this paint color have complained of an issue this similar. Headlights are too dim at night. We have family who lives in the country with limited street light and we are forced to use our high beam lights to even see down the road. I turn on my fog lights to add extra light but it’s still hard to see further down the road.

The headlights are dangerously dim. Purchased this vehicle used. Only used in the daytime the first months. My son started working night shifts and that's when we noticed that it did not light up in front of the vehicle. It was very minimal. I drove the car on a rainy evening and was terrified. Could not see in front of me. Had to drive next to cars to make sure I was in my lane. We cleaned the headlights, it did not improve. We purchased new and brighter bulbs. It is still too dim. It only lights up immediately in front of the vehicle and it is a very dim light. Light barely reaches maybe three feet in front of the vehicle, maybe only two. It is VERY dangerous. I am an experienced driver and I found it frightening to drive at night. My son is recently licensed and it does not feel safe to have him operate that vehicle.

In this instance, the headlight connectors required replacement and Kia extended the warranty to cover that work. Kia will not extend the warranty to 2015 model owners who are having the same problem and the dealership quotes a price of $1880 for just the parts alone.

The running lights on the front and rear drivers side work half of the time, the plate light seems to turn off when they do. They'll come on for a split second and then go out, or on a good day they'll stay on. Seems like a short in the wiring. It could be a safety issue at night!!!

Upon accelerating causes a lot of exhaust smoke and bogs down so I can’t get out of the way and others behind me cannot see a thing. Two Kia dealerships refused assistance. The first after I called 12/3 to report that my vehicle issue made additional hazard involving a semi (thank goodness no one wreaked) and it was still smoking and smelled as if something was burning. The other telling me it would be six months at least. The warning dashboard lights did not trigger during or after incidents. The only light that came on ever was the oil light the prior weekend. I had the oil changed, filters replaced as well as the headlights for the third time. Around 44k miles when issues started and escalated quickly. Other problems reported to Arapaho Kia a few years ago consisted of back passenger door not latching. Someone flagged me down on the highway as I had my daughter in her car seat on that side. No warning lights triggered, dealership unable to duplicate issue. Steering control keys controlling opposite functions or not working intermittently. Was told steering control harness needed replacement. Think that was at 18k miles but not sure. Did not have replaced at that time as it mainly affected radio functions hands free calling did stop working. I usually didn’t make calls in the car anyway. I was left with no other choice but to trade the vehicle in before something really bad happened or it self destructed leaving me without out a car still paying on. I could not be without a car for six months as Peak Kia quoted timeframe. Untimely fixing of recall on vehicle likely manifesting these other issues and causing additional damage to vehicle.

At 65 mph on a highway, there is practically no time to react to an animal or object on the road. I have emails from the manufacturer but I am unable to copy and paste them here. In my discussion with a representative from Kia, I was told I would have to contact the dealer and pay a $160 diagnostic fees s then pay for new headlights, that would be the same as are on the car now. Makes no sense.

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.

DP21003 · Throttle Control System Vulnerabilities
Opened Nov 12, 2021 · Closed Jun 20, 2023
Status: closed (inferred from source dates) · Vehicle Speed Control:throttle
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. 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.
