A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the “check engine” light in the instrument cluster. Illumination of the “engine oil pressure” warning lamp. My car will drive up to maybe 37mph and then the engine will seize up and go into safety mode and it becomes inoperable. THIS is a death trap if we suddenly stall out on the highway or at a higher rate of speed!!!! The dealership is basically saying oh well, it is out of warranty. I just bought this car from Banister Nissan on 6/5/2023. Less than 60 days ago.

My engine had been using oil at a very fast rate and I was just told that hyundai consume a lot of oil. I have had this car since 77k miles and have issues ever since I bought it. At first I had issues with it not accelerating on the interstate and then it would randomly stop while I was driving, almost like a car hiccup. I took it to the dealership, and other car shops and no one found anything wrong. Finally two weeks ago, I was on I85 and my car was driving really roughly and idling roughly as well. No lights came on until it started to decelerate on the interstate to 30 miles an hour and I had to pull off to the side of the road. Then a bunch of different lights came on and I turned it off and it wouldn't turn back on. I had it towed to the dealership, and they stated I had a bad engine, and Hyundai may replace it but it will take the shop 4-6 months to even take the engine apart to see whats happening. I'm out of a car for at least 4 months probably more, and there is nothing I can do. The mechanic is thinking there is an issue with the bearing.

2017 Hyundai Santa Fe. While driving, the vehicle stopped accelerating. The vehicle operated appropriately until half way through the drive. At stops, it would take several seconds (30ish) for the car to go about 20 mph (rough estimate). The car would not go above 50mph, and this took a few minutes to reach with the gas pedal all the way down. I parked the car and had it towed. After approximately a month at the dealership, the dealership text that there was a hole in the valve cover and that the engine would also need to be replaced. They did not say what was wrong with the engine and later stated, also via text, that to do a diagnostic it would be $350. I purchased the car used with approximately 45000 miles 10 months prior. At the time of the incident, there were 62000 miles on the vehicle. They stated that it would not be covered under warranty because I was not the original owner. I purchased the extended warranty at the time of purchase. They then filed a claim with that policy and we are awaiting an inspector to look at the vehicle. There were no warning lights prior to the issue. My family, husband and 3 children were in the car and it was dangerous because we were on a busy road and the car would not go to the speed of traffic. We are awaiting an inspector to look at the vehicle. The vehicle is currently still at the dealership. If requested, I am willing to have the car inspected. The incident occurred 5/12/2022.

WHILE DRIVING MY 2017 HYUNDAI SANTA FE SPORT 2.0T TO ENTER THE FREEWAY, THE CAR WOULD NOT ACCELERATE NORMALLY. IT STARTED TO SHAKE AND FELT LIKE THE ENGINE WAS "MISFIRING" AFTER SEVERAL MINUTES, I WAS ABLE TO GET UP TO 60MPH. I TRIED TAKING MY FOOT OFF OF THE ACCELERATOR AND PRESSING IT AGAIN BUT IT WOULD ONLY LOSE SPEED AND THEN I'D HAVE TO WORK MY WAY UP TO 60 MPH. I WAS TRAVELLING STRAIGHT AND ON A FLAT ROAD. ENGINE LIGHT WOULD COME ON WHEN FOOT WAS ON ACCELERATOR, THEN IT WENT OFF. ONCE I WAS OFF THE FREEWAY AND TRIED TO MAKE A RIGHT TURN FROM A STOP, CAR WOULDN'T ACCELERATE GOING UP THE INCLINE AND THE CAR BEHIND ME ALMOST HIT MY TAIL END. FINALLY,I TURNED LEFT TO GO UP THE HILL TOWARD MY HOUSE, I COULD ONLY GET UP TO 15 MPH BUT RPMS WERE BETWEEN 3500-4000. LUCKILY THERE WAS NO TRAFFIC BEHIND ME BUT I WAS AFRAID I WASN'T GOING TO MAKE IT UP THE STREET OR THAT SOME CAR WOULD COME UP BEHIND ME AND MY CAR WOULD STOP. IN ORDER FOR A CAR TO BE SAFE IT NEEDS TO BE RELIABLE IN ACCELERATION AS MUCH AS BRAKING AND STEERING! I HAVE AN APPOINTMENT AT THE DEALERSHIP DAY AFTER TOMORROW.

DURING ACCELERATION FROM A STOP SIGN/RED LIGHT OR TURNING THE ENGINE HESITATES FOR APPROXIMATELY 5 SECONDS AFTER SEVERAL TRIES BEFORE REACHING DESIRED SPEED. WHEN USING CRUISE CONTROL ON FREEWAYS THERE IS A 10 TO 15 SECOND DELAY WHEN ACCELERATING OR PASSING ANOTHER VEHICLE WHICH IN ONE INSTANCE CAUSED A NEAR ACCIDENT ON A HIGH SPEED FREEWAY. MY VEHICLE SLOWED DOWN CAUSING OTHER VEHICLES GO AROUND ME PASSING FROM THE RIGHT SIDE LANE. THESE HESITATIONS HAVE CAUSED ME SEVERAL NEAR ACCIDENTS AND MAKES ME NOT FEEL CONFIDENT WHEN DRIVING THIS CAR. I HAVE TAKEN THE VEHICLE TO THE DEALERSHIP ON MANY OCCASIONS AND THEY REPORT NO ERROR CODES SHOW UP AND, THE MECHANIC CANNOT DUPLICATE THE PROBLEM. HOWEVER, THE DEALER REPLACED THE TRANSMISSION EARLIER THIS YEAR. THERE HAS BEEN NO IMPROVEMENT. I HAVE REVIEWED MANY OTHER COMPLAINTS OF THIS HESITATION PROBLEM. WILL IT TAKE DEATH REPORTS TO HELP US OWNERS? MY ISSUE BEGAN IN 2018 RIGHT AFTER PURCHASE AND THE PROBLEM IS OCCURRING MORE OFTEN NOW. NO HELP IS IN SIGHT WHEN HYUNDAI AND THE DEALERSHIP REFUSES TO ADMIT THE PROBLEM AND MAKES ME AND OTHER OWNERS FEEL LIKE WE DON'T KNOW OUR VEHICLES OR OUR OWN MINDS!! WE NEED HELP BEFORE A DEATH OCCURS NOT AFTER!!

THIS HAPPENED MULTIPLE TIMES IN 2017 AND 2018 BOTH ON THE HIGHWAY AND CITY STREETS. IN 2018, TAKEN TO PEARSON HYUNDAI AND COULD NOT BE FIXED BECAUSE NO ERROR CODES. AFTER A DANGEROUS, IDENTICAL INCIDENT ON THE INTERSTATE IN MAY 2019, TAKEN TO PEARSON HYUNDAI. THEY PERFORMED A TCU AND ECU SOFTWARE UPDATE MAY 21, 2019. THIS LATEST INCIDENT IS A REPEAT OF THE MAY 2019 PROBLEM. THE PROBLEM IS RANDOM AND UNPREDICTABLE BUT OCCURS ON BOTH HIGHWAY AND STREET SPEEDS. THE INABILITY TO ACCELERATE WITHOUT WARNING WILL EVENTUALLY CAUSE AN ACCIDENT. WE ALSO OWN A 2016 SANTA FE SPORT TURBO AWD THAT HAS NOT HAD ANY OF THESE ACCELERATION PROBLEMS. CHANGES WERE MADE IN THE 2017 MODEL YEAR TO THE ENGINE AND TRANSMISSION THAT ARE IMPACTING ACCELERATION.

3DP24001 · 3.3L Engine Loss Of Motive Power (lomp)
Opened Feb 8, 2024 · Closed May 16, 2024
Status: closed (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) received a petition on February 2, 2024, requesting a defect investigation into an alleged defect of the "engine" on the following vehicle model: 2017 Hyundai Santa Fe vehicles equipped with the 3.3L V-Shaped GDI Lambda-II engines. The petition cites allegations of a loss of motive power, often resulting in an engine seizure. The stall is preceded by a knocking sound, decreased performance and no warning lights. An analysis of the subject vehicle population was undertaken using complaints submitted to ODI along with manufacturer data. It was determined that the frequency of events is low for the subject population, while those that specifically report a loss of motive power event have a high mileage at the time of incident. The 2017 Santa Fe is equipped with a service interval reminder for the consumer that must be set by the consumer themselves or at a dealership. A Technical Service Bulletin (19-EM-002H) instructs the dealership to set the maintenance reminder at the completion of routine maintenance service or anytime a repair is performed that requires new engine oil. This maintenance reminder will help reinforce the need for proper oil maintenance intervals. Additionally, the Santa Fe vehicles with 3.3L V-shaped Lambda-II engines will be added to Hyundai’s existing Technical Service Bulletin (23-EM-007H) related to combustion chamber cleaning. These actions will help limit negative consumer incidents related to loss of motive power. Lastly, Hyundai has extended the limited engine warranty for MY 2013-2019 Santa Fe vehicles equipped with 3.3L V-shaped Lambda-II engines included in the Petition. The updated coverage is 15 years, or 150,000 miles and details are contained in Technical Service Bulletin 24-EM-003H. In view of the service interval reminder, combustion chamber cleaning, and extended warranty actions being taken by Hyundai, ODI is denying this Defect Petition. The agency reserves the right to take additional action if warranted by future circumstances. To review the report cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

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.
