I am writing to formally lodge a complaint regarding the recent theft of my 2019 Hyundai Tucson, which I believe was exacerbated by a software update provided by Hyundai. Several months ago, I had my vehicle updated with a software patch at a Hyundai dealership, specifically intended to address vulnerabilities related to vehicle theft. However, despite the update, my vehicle was stolen on August 8, 2024, and later totaled in a crash. I have been informed by police and insurance company officials that thieves are now exploiting a method involving breaking a window and popping the ignition, as demonstrated in online videos. This method remains effective despite the software update. Adding to my frustration, Hyundai placed a sticker on my driver’s window to indicate the software update. This inadvertently advertised to thieves that my vehicle was among those with the known vulnerability, potentially making it a target.

formance exhaust. I bought catalytic conVerter that they told me to buy for 600+ dollars and took it to child's shop they told me that the catalytic converter isnt clogged nor is it affecting my car and provided me with these codes about the camshaft and crankshaft (P0017,P000B, P000A) which they stated hyundai should have fixed under the engine warranty because it was a recall on these engines on this year car. They stated that even if fixed the converter my car would still perform the same and 3 other mechanics have said the same and stated hyundai would have to fix it. After oil changes the oil consumption in my car is constantly getting oil before its even due for another oil change. I have already paid so much just by having people look at it, buying oil, parts, and etc. i am furious to know that i was sold a car that was recalled with engine problems and been having problems since i got it. I have 2 kids i have to get to and from school and this my only transportation. My car has been misfiring and not going over 40 miles. This is my only vehicle and hyundai has put me in a messed up situation. The recalled was may 2022 and hyundai sold me this car june 9 2022. I contacted the june 15, 2022 about the engine light they kept turning off. Car is stalling, making noise, not holding oil. Have to top oil weeks after getting oil changed

The check engine light came on and then started flashing. It was 3 quarts low on oil and there were still 1,000 miles left before the next oil change. The oil has been changed regularly since we purchased the Tucson in December 2023. A mechanic looked at the vehicle today and said metal shavings were in the oil and the engine needed replacing. The 2019 Hyundai Tucson got good reviews and was considered a safe vehicle for teen drivers, but now I'm wishing we purchased something else for our kids to drive.

’ve replaced the catalytic converter two times , the check engine light is on so it says I need another catalytic converter, that was in June 2024. The car was at the shop yesterday, needs catalytic converter and oil is pooling all throughout the car , fumes from the exhaust are coming back into the car which makes me physically ill. The engine revs and slows down by itself, it goes through oil on such a regular basis that I have to carry a full size jug of oil with me at all times because I need to put it in before I leave work and when I am on my way back home , the dipstick will be dry.

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.
