I am writing to formally file a complaint regarding my 2023 Kia K5 and the unacceptable experience I have had following a dangerous brake system failure. On Wednesday June 24th, while driving on Route 22 in New Jersey, my vehicle's brakes suddenly became extremely hard, making it incredibly difficult to stop. There were no lights on indicating an issue, neither any concerning sounds prior to this incident. I came dangerously close to being involved in an accident and was left extremely shaken. The situation was serious enough that my father had to come retrieve both me and my vehicle because I no longer felt safe driving it. I brought my vehicle to the Kia dealership on Friday, where I was informed that the repair would cost over $1,000. I find this extremely concerning given that Kia has previously recalled brake system components on other models for similar issues. While I understand my vehicle may not currently be included in that recall, a brake system failure on a 2023 vehicle is unacceptable and raises serious concerns about safety and product reliability. To make matters worse, I never even received a phone call from the service department to explain what was wrong with my vehicle or discuss the recommended repairs. Instead, I received nothing more than a text message with a link to a video. The first words I heard were, "Your brakes are really bad." For a customer who had just experienced a frightening brake failure that nearly resulted in an accident, I expected the courtesy of a direct phone call to explain the diagnosis, answer my questions, and discuss my options. Receiving only a video link felt impersonal and dismissive given the seriousness of the situation. After repeated back and forth with Kia corporate over the span of two weeks they determined that the repairs are on me, and I was offered nothing, even though this issue was of no fault of my own.

The kia since bought brand new would have alignment issues even after getting alignments every 3-4 months and the dealership claim that they don’t whats causing constant misalignment after seeing theres no signs of external damage. Due to the misalignment it wears down the tires and made one of my tires explode on the road. Also the door seal on the driver side gets a chunk ripped out from just opening and closing the door over time. Also the breaks, whenever I break from speeding to slow down the speed the steering wheel shakes as well

This is the letter I sent to Kia: Dear Sirs, I own a 2023 Kia K5 EX that I bought new and currently has about 8500 miles on it. Today, while driving on I95 in Florida, I had my right rear tire blow out. I could tell by the feel of the car that I had a flat before the systems warned me, but that is not why I’m writing you today. While I was working my way over to the right shoulder to stop, all of the waring lights came on and the brakes stopped working. Now I want to be clear. It wasn’t a failure of the brakes themselves. It was not the anti-lock brake system. The brake pedal itself locked and would not let me apply the brakes. Again, I want to be perfectly clear here. I am now driving on a 6 lane highway at about 50 miles and hour on three tires with no working safety systems and I cannot slow down the car. Eventually, the brakes came bake on line and I was able to stop the car. However, If the traffic suddenly slowed down, as is common on South Florida, I would have had no way to avoid a collision. I do not know if this is a programmed response to a tire blow out or a major flaw in your safety systems. If it was designed that way, fire the moron who designed it and have it fixed. If it’s a flaw in the design, have it fixed. I cannot believe how dangerous a car you let me drive. Sincerely, [XXX] 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.
