I took the car to the dealership to get the light fixed, I was told there were some loose wires and they fixed it. 2 weeks later it started happening again, I returned with the car and got another appointment, before the appointment date, the left low headlight warning light came on. I returned with the car and was told that the harnesses and wiring are damaged and need replacing. I have had the drivers side light replaced on 2/26/21 and was back on 4/16/2021.

On Saturday, November 23rd, while driving down the highway the check engine light came on and the car would not accelerate past 40 mph. When accelerating from a stop, the car's acceleration is greatly diminished. The car was checked out be a local Hyundai dealership. After running a diagnostic, the mechanic reported the following: the car has a knock sensor code, valve stem seals are leaking a little bit, compression test showed low compression on all four cylinders (between 130 and 140) normally it is 185. This indicates wear in the rings and losing compression that way. Dealership says only option is to replace the engine. Currently have 95k miles on the car. I believe we are the second owners of this car.

I am so hurt that I had to spend all this money on a new vehicle and when it was almost paid off, the paint was coming off. It is no fault of mine because there are toooo many areas all over the vehicle where there are chip areas forming. The biggest, most noticeable area01 is on my hood.

I have had several incidents of my car running out of oil before the recommended oil change date or mileage. The low oil light never comes on. On the last occurrence of my oil being too low the check engine light did come on and the engine began to make a knocking or ticking-like sound. I have already had to have the catalytic converter replaced on this vehicle and it is around 90,000 miles.

A few months back my car started to loose its ability to accelerate on the highway. I stopped to get my oil changed to see if that would help but the acceleration was still very limited. Now a month ago, my car started pouring smoke out of the exhaust. It was brought to a mechanic who said it was a turbo and or engine issue. I took it to a Hyundai near me for a clear diagnoses and they diagnosed it as needing a new turbo. I got a new turbo put into the car. My car worked for 1 day before pouring oil out of the bottom of it. I then had a new turbo put in. My car worked well for 1 week but now is leaking oil from the exhaust and making loud knocking, go kart noises. Most people I have talked to say it's the engine and that these problems are way too common in Hyundais well before 100k miles. My car has also been peeling white paint from the hood of my car for 2 years. I have passed hundreds of white hyundai's with the same paint problem.

We were consuming about a quart of oil every week and a half. I drive over 60 miles a day. We added oil until we could check it out. First dealership said that no visible exterior leaks so they told us to take to Hyundai. Once at Hyundai we were told compression was down and we needed a new engine, Catalytic converter, and turbo. Our extended warranty only approved a short block. Said we have sludge and we have to cover the rest of the parts that have sludge but we proved our oil changes and used synthetic oil. They will not give us proof of anything. Hyundai is known for this and won’t cover anything. Hyuandai Beaverton and Ethos is being horrible.

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.
