There is a known issue with this particular engine burning oil. I’ve had to replace three catalytic converters, among other parts in the exhaust. I am 3000 miles away from an oil change and my engine is flashing lights and stalling while running. Something needs to be done as it can cause the engine to fully fail

My wife was picking up our daughter from school. The car shutdown as my wife was getting into the left hand turn lane to go onto our main street. The warning dash lights turned on, but she could not turn on the car. She called me and I left work early to help her out. She called me a few minutes later telling me she was able to get the car started but that it sounded as though "rocks were in the engine." When I got home, I opened the hood and checked the dip stick and noticed metal flecks and shavings on the end. I tested the dipstick 3 more times and each time I inspected it noticed the flecks and shavings. I then called a tow truck to have the car transported to Hyundai. The sudden engine failure led me down a rabbit hole online and realized this is a widespread issue with a lot of Hyundai vehicles. Luckily, the dealership is replacing the engine since it is still under warranty. I plan on getting rid of the vehicle as soon as possible. The quality of their engines is awful. Despite taking the car for regular maintenance it still failed. It's also telling that the dealership I'm at has several other Hyundai's they're servicing FOR THE SAME EXACT ISSUE! I was also informed it can take up to a month for the engine to be replaced. Stay away from Hyundai and Kia. There's a reason why they have the types of warranty's for their vehicles. They know they're unreliable and faulty.

The engine in my 2018 Hyundai Tucson is burning oil at an excessive rate. I have to change my oil every 2000 miles or less due to engine knocking if I don't. Due to the excessive oil consumption, I now have to replace all 4 engine coils for over $1500. There have been multiple codes given to me every time I take the car in, including 3 times for the knock sensor which was replaced under a nationwide recall. Hyundai settled a class action case with some consumers, under the radar, for excessive oil consumption and is leaving every other consumer unaware unless they start digging for information. One of the times my engine light came on, I was on a very busy California highway and my car went into limp mode. This is unacceptable and a major safety hazard. My car is currently at the dealership for the third time and not drivable until I spend $1500 to repair a problem that their faulty engine has caused.

It started [XXX] when i took my car to the dealership due to it going into limp mode. The dealership took it in and said it was throwing error code p1326 which is the knock sensor code. they replaced the knock sensor, drove my tucson home after the replacement, by the time i got home it went into limp mode again, took my car back to the dealership turns out it was a faulty sensor they received. So the dealership replaced the sensor again, did not have an issue with it until decemember 2023, so i took it to get the error code read again and it was the p1326, so i make an appointment with the dealership to bring it back in and they said hyundai of america says it needed the combustion chamber cleaning, which i had to pay for. even though it was throwing the p1326 error code. but after the cleaning is done i pick it back up and not even ten miles from the dealership my car goes back into limp mode, so i turn around and take it back. they just got back to me on [XXX] saying hyundia of america is declining to replace my engine since its no longer under warranty.

We had previously been to Allen Samuels Hyundai in Jackson, TN for an oil consumption test. We received a call the following week telling us that the mileage was too high for warranty or to continue the consumption test. I was adding a quart of oil once a week. I never had any lights appear for any problems due to low oil or overheating. On a Sunday evening we were returning home on [XXX]. We had the cruise set at 70 mph. We started to lose power and the engine started to shake. The car quit and would not restart. We called for a wrecker to tow us to the nearest shop. We were informed the following Friday that we had low compression and needed to replace the engine. Something should be done due to numerous engine failures.

I was driving on the highway at 60mph. I had driven for 30 miles. My car began to shake and would not accelerate. I made my way to the shoulder on the highway and was able to coast down an exit. My engine had died. Right before this occurred the check engine light went on. I still was able to steer and brake. I did get off the highway only because I could tell the car was losing power. By the time I stopped it was dead. I have had my car checked out because of the way it drives. It burns oil at a rate which should not occur. I keep it maintained and in good condition. As I said I have had concerns about the way my engine runs yet have been told "its like a truck" and this model "burns oil" I did not get hurt as I am an experienced driver. I could tell that the engine was failing and was able to get to the shoulder. Had I not i would have been killed as i was on a highway and engine failed. My car is currently at the dealer. It has 107000 miles. It is just 7,000 miles over warranty. There is no reason a car that is taken care of should have engine failure with no signs or symptoms. From what I've read looks like this is a newer problem with 2018 vehicles. I am prepared to supply any maintenance receipts or work done on the vehicle. Clearly there is a safety risk. It also appears its happening once the car has high miles. This is very disturbing, scary and sad that it appears another person actually tried to fight this, and Hyundai won.

issues with the 2018 Tucson- Transmission has always sputtered, had numerous updates and resets for it. still an issue. also it doesn't want to go into gear sometimes and bob when going into drive, or reverse. slow pick up from a complete stop, the other morning it became a safety concern when I had my daughter in the car. The car start to move when I stepped on the gas, then stopped in the middle of the intersection of [XXX] four way. The RPM's as I was stepping on the gas was shifting between 5-7 and the car it wasn't moving. Engine- in September I noticed my oil pressure light flashing on and off, this pointed me to check the oil. the oil was very low, added oil to the vehicle. since then I have had the dealer involved due to high oil burning . in [XX] I had an oil change done and no oil was found in the engine after I had placed oil in it prior. they did the oil change and I went back at the end of October and they had noticed my oil burnt off again. they did the combustion cleaning and returned the vehicle back to me [XXX]. Since then I drove 950 miles on the vehicle, Last Saturday the oil pressure light was flashing as I took my daughter to her dance class, I checked the oil and the oil was reading below the low mark on the dipstick. I returned to the dealer that morning for the oil consumption test, in which they said it was only a quart low which seemed odd to me since it was low on the dipstick. I have had corporate involved as well and all my concerns have gone as this is normal for your car. Hyundai has had issues with my Year Tucson, from my research since I started having the issues they have settled a lawsuit for the problems with the engine and transmission which I have in it.my research, as the vehicle ages, the engine burns large amounts of oil and transmission failure, stopping while driving. I would like them to replace the engine and transmission before my warranty is up. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
