My car was working fine since I bought it in April 2023. I passed inspection in November 2023. On January 24, after driving for about 15mins, my check engine light began flashing. The car would not accelerate over 25mph. I brought it to a dealership where it has been for 3 days. All communication about this problem was initiated by me, and the only answers I get are vague comments about testing.

Excessive oil consumption due to piston ring failure. Clogged catalytic converter due to metal shavings from piston ring failure. This put my safety and the safety of others at risk due to potential engine failure which disables all other safety features of the vehicle. confirmed by a hyundai dealership. inspected by a hyundai certified dealership. No warning lamps but oil consumption has been an ongoing issue.
I just purchased this car and I can't insure it in nys all of the insurance company's are claiming they black listed this car and can't insure it I'm not really sure how it's legal to sell somebody a 21000 car and you can't drive it because you need insurance in nys

The car stopped mid-drive with no warning light or anything in the middle of the road. When we took the car to the nearby mechanic they had told us that it was an oil consumption issue with our engine. He refilled the oil and the car was operational again (the oil was changed <2 months prior and <1.5k miles). The first time this happened the engine was making unusual noises several months ago and we refilled the oil at that time and it resolved. In other words, despite being diligent in routine oil changes according to usual maintenance standards the car is burning through it and more importantly not even alerting us about the issue before causing dangerous complete engine shut down mid-drive.

This is the 2nd time I have had a sensor indicator. The first was a knock sensor where my car barely made it across the road. Now another code for intake issues.

This is the 2nd time I have had a sensor indicator. The first was a knock sensor where my car barely made it across the road. Now another code for intake issues. If my car dies and I get hit Hyundai is liable. I know many people that have issues with their Hyundai dying and are without their cars waiting for repairs for. months and months, but the fact that I have a grandson and my car could die is incomprehensible. These cars need to be pulled off the market.

I was driving home from a family get together with my husband and daughter in my car. We smelled something burning, and suddenly smoke was coming out of my center console. I pulled over and flames were coming out of the driver side. As soon as we evacuated the vehicle, it burst into flames. There was no warning, nothing lit up on the dashboard to warn me of this hazard. A witness was driving behind us and called 911 when he noticed flames underneath my vehicle right before I pulled over. A police report was filed and it was reported to my insurance agent, it is currently still under investigation since it just happened 2 days ago during a Holiday weekend. My safety and my family's safety was put at risk due to no warning, how fast the vehicle went up in flames, etc. The car was a total loss.

Catalytic converter failure. Driving and vehicle slowed down while attempting to pass another vehicle in spite of foot being on accelerator. We were nearly hit head on by a semi trailer. Vehicle unable to increase speed over 50 mph. Taken to dealership. Diagnosed with problem with catalytic converter failure. The vehicle has 82,000 miles. Failure occurred suddenly. Vehicle has also been burning oil since June 2022. Dealership and Hyundai have covered nothing and offered no solutions other than to replace catalytic converter at cost of $3,693.35. There are multiple other complaints of exact same issue online and the safety of this vehicle is questionable as vehicle will refuse to accelerate suddenly which results in a dangerous situation for vehicle's occupants.

1DP22003 · 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.
