I am filing an urgent complaint against Hyundai motor America for a direct violation of the national traffic and motor vehicle safety act. The manufacturer is actively refusing to honor and execute the mandated remedy for federal safety recall 263 (NHTSA campaign 24V-529). My 2024 Hyundai Santa Fe XRT suffered an immediate transmission failure, throwing DTC P086800, which is the precise fail-safe error logic covered under this safety recall. When escalated to Hyundai Motor America Corporate Consumer Affairs (Case #XXX), a corporate case manager issued a formal written denial. The manufacturer explicitly stated that the safety recall remedy would not be covered because the vehicle is "past its 10-year/100,000-mile warranty period". This denial is legally fraudulent. Under federal law, safety recalls do not carry mileage, time, or warranty status restrictions. Furthermore, my vehicle is a 2024 model year, making the manufacturer's claim of it being "over 10 years old" a clerical impossibility. Because my vehicle is a primary tool for my livelihood as a rideshare driver, this unlawful denial has caused extreme, compounding injuries. The vehicle entered limp mode and was rendered entirely undrivable. Hyundai's refusal to provide a loaner vehicle or repair the safety hazard has completely cut off my ability to earn an income. As a direct result of this prolonged corporate delay, I have suffered sudden job loss and immediate housing displacement, rendering myself and my family homeless and stranded in the state of [XXX]. I have suffered greatly having to sleep on the streets due to this non-compliance. I request that the National Highway Traffic Safety Administration immediately investigate Hyundai Motor America Case Management for systemic compliance violations regarding Recall 263, and compel the manufacturer to replace the failed transmission assembly immediately at zero cost INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 2024 Caligraphy trim line, has a unique illumination for all dash controls that control; AC, seat heat, seat AC, fan AC, steering wheel heat, ect. Each of these controls are illuminated with a dull Amber color that is impossible to see in bright sunshine, and difficult in all daylight situations. This force the driver to take their eyes off the road to insure proper calibration of each. I confirmed with the sales manager of my serivice dealer Hyundai Nashua ….he drives the same model there is no illumination adjustment that will make the controls visible in sun. Other trim lines have different illumination of the same controls. It would seem this is an easy swap and fix

Despite having the DCT software recall repaired, today the parking brake disengaged after the car was idling for a few minutes at my son’s school. It lurched forward, startling me, and then I was alerted that the emergency parking brake deployed. The rollaway could have injured a child in the parking lot. No alerts or lights have been on prior. Additionally, after the rollaway incident, I was stopped at a red light, and my brakes depressed halfway. The last few weeks the acceleration from stop is difficult, and the brakes shudder and partially depress, especially when driving over a bump - feeling every minor flaw in the road rattling beneath my foot on the pedal. To also be mentioned - I have retained an attorney to pursue a Magnusson Moss cash & keep settlement on the car. From June - August 2026 the car was out of service, 4 repair orders, 2 dealerships, and a FSE I demanded finally found & diagnosed faulty O-rings causing the freon to leak and the AC to fail. The car also smelled strongly of fuel one full day, and the dash & steering wheel felt hot to the touch - but no defect was found or diagnosed.

On May 30, 2026, my 2024 Hyundai Santa Fe was involved in a multi-impact interstate collision in the Sandy Springs/Atlanta area while traveling with my family which includes 1 year old kid. The vehicle was struck from behind, spun out, and impacted the concrete highway barrier multiple times before coming to a stop in the travel lanes. The collision resulted in substantial structural vehicle damage, and occupants sustained head concussions and bruising. The airbag system did not deploy during the sequence of impacts. I am submitting this report to request an evaluation of the crash parameters and deployment logic to determine whether the system operated within its intended safety design specifications under these specific multi-impact conditions. I don't have the footage but i have seen on police laptop of the incident.
