I have been dealing with ongoing engine performance problems for over a year. My Tucson consumes oil at an abnormal rate, and I constantly have to refill it. There is also sluggish acceleration, and the Check Engine Light has stayed on despite multiple inspections and maintenance efforts. I’ve seen hundreds of complaints about this exact issue from other Hyundai owners. I also found that an NHTSA investigation is ongoing, yet Hyundai continues to deny responsibility, often blaming the issue on the owner. I believe this is a safety concern and a manufacturer defect that needs to be addressed before more drivers experience full engine failure. Please investigate this further and include my VIN in any future action or recall.

The reason of this complain is due to excessive oil consumption which now damaged my catalytic converter against Hyundai Motors America. The complained started 2021 where we noticed that the low oil engine light up after only 1500 miles from last oil change. We submitted the complained with dealer (Carlsbad and Escondido CA) and my car failed 3 consecutive oil consumption test and Hyundai performed an engine cleaning, claiming it was going to fix the problem. This happened when the vehicle was still under warranty. At the time they said that if this did not fix the problem, they were still going to fix the car since the issue happened under warranty. The engine cleaning DID NOT fixed the problem, my car no longer has warranty and my catalytic converter fails and makes the vehicle inoperable in highway (engine ceases to accelerate) . We submitted a complain with Hyundai corporate and they denied fixing our car since the vehicle was no longer under warranty. I would like to ask for them to fix the engine and catalytic converter make the car operable again.

My engine light came on while we were still in the city in Savannah so we stopped by an autozone and changed the spark plugs so the engine light stopped blinking but when we got about 20 miles from home it stopped going we had to pull over it started smoking and it was really hot but the temperature had never moved we had it towed home!! I keep my maintenance up regularly on my car I had 2 mechanics check it out they both said the piston is breaking the spark plugs and it’s something down in the motor that’s doing it I should not have any motor issues at all with my car!! Especially when I do my part at keeping it up I was quoted 7,738 to fix my car which I don’t have both mechanics said the engine in those cars are no good and it’s been recalls on them just not my model it’s not right I’m out of a car and no way to work or no way for my kids to get around they have to ride in Lyfts and Ubers with strangers I feel like my car should be fixed because I did my part at keeping it up and I’m still out of car and frustrated due to the companies negligence!!

There was never an illuminated oil light or message of any sort prior to failure. this vehicle has had oil changes regularly and never been an issue till now. With Hyundai not having a recall on this engine, and seeing many other reviews about this same issue it is a very dangerous issue leaving people stranded and loosing power in times where serious harm issues could occur and this issue is very costly being that the engine will have to be replaced. As a consumer taking care of the vehicle and still the engine failing due to the lack of integrity of Hyundai I believe Hyundai should step up and make it right and take care of the people who have spent there hard earned money on these cars and are now left in the dark.

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.
