The 3.3 liter V6 GDI engine failed while driving at approximately 136000 miles. Heard a ticking noise start shortly after leaving home, and had hesitation and shaking upon acceleration from a stop sign, but saw no warning lamps. Went around the block back home to find out the ticking noise was under the hood. Motor oil was almost 3 quarts low, but only 2/3's of the way through the service interval. Checked for leaking, saw none dripping, but did see oil on the under of the rear differential. I then let the car run for minute or so in the garage and looked for leaks. I saw no active leaking and ticking was quieter, so I drove to a close gas station to get a little gas and test drive, still no warning lights. On the way back, about a mile from home, the engine light came on, despite the ticking sound being gone. Within a quarter mile, at the next stop sign, I let off the brake to accelerate and the car started rolling backwards, causing the vehicle approaching from behind to swerve into the turn lane. The vehicle was no longer running, and wouldn't restart. Towed to local mechanic and was told 2 days ago the engine was seized, and replacement was needed. I have not contacted any dealership or the manufacturer, as I the second owner and do not have a warranty. However I have spent the last 2 days reading seemingly 1000s of articles and forum posts related to this engine, whether it be in a Hyundai or a Kia. Several of the articles I have read about this 3.3 liter GDI Lambda -II engine and it's horror stories, referenced this nhtsa site as a place where complaints can be made, so here I am. Many articles describe the same problem.. hesitation... ticking.. sudden mysterious oil loss... little, if any warning... complete failure while driving, putting safety at risk. With the problem with engine so blatantly rampant, it is my fear that after I scrap this vehicle, there will be a recall. Over the phone quotes, and online pricing have ranged from $7500-20000 for repair.

My 2015 Hyundai Santa Fe GLS 3.3L engine started ticking sound while driving in residential are with the speed below 25miles. Within seconds, Engine started screaming and dropped power in the middle of the road. It is a huge security and life threatening risk. I was lucky that I was driving in residential area with very slow speed, and just imagine if it happens in the middle of the freeway cruising at 65MPH. It is at 107k miles and not sure what to do at this time. Hyundai better recall there 3.3L V6 engines and help us our here. My vehicle is now dead and I have nowhere to go to get help because it a huge cost to get it fixed.

We were on our way home from the children's hospital in Philadelphia for my daughter (4 hours away from home) and my 2015 Santa Fe with the 3.3L motor began to knock. My dad (who is very mechanically inclined) pulled over at a gas station and checked oil and other fluids. It was low, even though I just had oil changed 900 miles before and it was checked before our trip to the hospital. We bought oil and put it in. Knocking was still there but was not as loud. We got back on interstate. Few miles up the road it completely lost power, extreme knocking, no lights on in the dash or any gauges out of normal range. He checked oil and it was completely empty but there was no oil trail or anything. We coasted into a crossover and that's when he saw the connecting rod under the car.

While I was driving on the highway in the left lane, smoke came from the engine, then it started coming from underneath the car. The car turned off. I was forced to stop on the left lane of the highway and exit the vehicle and walk as far away as possible. I called 911, then I noticed fire coming from the engine. This was unsafe for myself as well as other riders on the highway. Firefighters came and put out the fire. Once they left, I was left by myself waiting for the tow truck to arrive. No police officers helped to keep myself safe while waiting on the left shoulder once the highway re-opened. When asked if I needed a police report, the police officer said no because it wasn't a crash. The vehicle was inspected by my insurance company and it was deemed a total loss. There were no warning signs or messages or symptoms prior to the failure at all.

While driving, there was a very loud pop, following by the sound of glass shattering. I was unable to tell which window was broken since it was dark outside (early morning before sunrise), but I could hear wind coming into the car. I pulled over and inspected my car, and that is when I noticed that the middle portion of the panoramic sunroof was completely shattered. Fortunately, the inside cover was closed, otherwise the glass would have fallen on top of my head & covered me in broken glass from the sunroof, as well as the front and rear seat passengers. I am grateful that my children were not in the car with me when this occurred. My safety was at risk 1), due to the loud pop/explosion sound which startled me & caused me to swerve while driving. 2) the shattered glass falling from the sunroof onto my head and the rest of my person, as well as any passengers, could have caused serious injury especially if glass had fallen into the eye of anyone inside of the vehicle, especially the driver. This could have endangered others by causing me to collide with another motorist on the roadway. Prior to the shattered sunroof, there were no warning signs to indicate anything like this would happen. No warning lamps, no visible defects, issues, or other symptoms of failure were present before this occurred. The issue of exploding sunroofs has been a well-known issue with Hyundai vehicles with panoramic sunroofs and resulted in a recall for some models of Hyundai. I contacted a local dealership after my incident, and he was aware of the unexpected shattering of the sunroofs, but advised that my vehicle was out of warranty, and that my model year was not included in the recall group, and therefore it was not covered for the incident. There are many online forums that discuss this issue for various Hyundai vehicles in the USA & Canada, including class action lawsuits regarding the issue. Photos taken of the damage for insurance claim. Stress marks seen in photos.

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.
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.
