Dealer said I would have to replace the oil pan gasket ($600)before they would start the test from Hyundai. Loss of power or engine seizing could be dangerous. I feel Hyundai shoud replace the engine and reimburse me for the oilpan gasket.

My engine has been losing oil with no leak. 1st shut down was 02sensors crank shaft , check engine light still on took it fixed it not sure how. Brought it in for upgrade in security took it out and a week later didn't start. Now entire exhaust is gone it's still burning oil I called ciorperate because he would not acknowledge the burning oil. So we will start this every 1000 kile test x3 so it may be diagnosed but they still want ne to pay 2600 fix exhaust that is directly linked to sludge and burning oil!? I do nit know what to do but I have already put 1000s in fir service rental tow I literally cannot pay 2600 to get car back to prove the problem and eat it it isn't fair well jotting is but this has got to be illegal so ehow... I hope

My engine light began blinking and the engine went into emergency mode on 3 separate occasions, and would not go over 40 mph; there was no prior warning. The first incident was in February of this year; the second was in April of this year, and the third occurrence was on 7/28. I purchased my car on 10/8/19 from Fred Beans Hyundai of Doylestown used, with about 12,000 miles on it. It now has 34,426 miles on it. I don't know what's causing the problem, and there haven't been any engine recalls. All the open recalls on it were serviced. When all the traffic around me is doing 60mph or better, this is hazardous stuff! My car has been towed to Fred Beans Hyundai of Langhorne for repair.

My safety and others is at risk because it suddenly decelerates and is very likely to cause an accident.the car has been dropped off at dealer who told me they would “try” to look at it early next week. Its not been inspected by Police, Manufacturer or ins reps. The same problem occurred on Dec28 2022 and again in April of 2022. In Dec they replaced the “knock sensor”. In April the code had been cleared so the dealer said there was nothing they could do. Im in a rental vehicle now because the dealer did not have a loaner for me.

Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020. On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles. The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.
Consequence & remedy
Consequence: An engine compartment fire can increase the risk of injury or crash.
Remedy: Hyundai will notify owners, and dealers will replace the HECU fuse. For 2019-2021 model years, the Electronic Stability Control (ESC) software will also be updated. Recall repairs will be performed free of charge. Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. The recall began November 2, 2020.

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651.

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.
