On August 3, 2026, while operating my 2024 Kia Telluride, I experienced a catastrophic and total failure of the service braking system. Without warning, the brake pedal went straight to the floorboard with zero hydraulic pressure or stopping power, resulting in a crash into trees. ​The vehicle was towed to Gerber Collision for accident repairs. While the exterior body damage was repaired, the body shop is not equipped for internal hydraulic or component failure analysis. Furthermore, Kia America has been notified of this critical safety defect but is refusing to cover the diagnostic/inspection fees to investigate the underlying root cause under warranty, attempting to pass the cost onto the consumer. ​This is a severe, life-threatening safety defect involving a total loss of brakes on a nearly new vehicle. I request that NHTSA log this complaint and investigate potential systemic hydraulic or master cylinder defects in the 2024 Kia Telluride platform.

The tire separated after only 20k miles. Mechanic stated that I still had half of the tires life left. Was advised not to drive more than a mile on it as it could blow out and cause harm to myself and 2 young children. I had two new tires put on the vehicle. My mechanic will be checking the two remaining at every oil change I have in the future. There was no warning, my vehicle started violently shaking and veering heavily to the right, so much I had to fight it with both hands. Kumho (tire manufacturer) has ignored my calls and emails. Kia told me they cannot help me and to reach out to Kumho.

am the owner of a 2024 Kia Telluride, VIN [XXX] . This is the 2nd Telluride we have and total 3rd Kia we have. I am writing to formally report a design defect in the rear seatbelt system that poses a serious child passenger safety hazard. In the second row, where my child’s car seat is installed, the seatbelt buckle is positioned extremely low and close to the seat base. This placement makes it nearly impossible for a child to buckle themselves in and causes delays in securing them quickly. In emergency situations, this design could also prevent a child from unbuckling themselves promptly, creating a serious risk if rapid evacuation is needed. Both in everyday use and urgent scenarios, this flaw can lead to improper restraint or dangerous delays in ensuring a child’s safety. I called Kia Consumer Affairs on Tuesday August, 12th 2025 Case # [XXX] and was told there were no available solutions or suggestions. I am not satisfied with this response, as this is not a matter of convenience but of safety compliance and proper usability for child passengers. As a loyal Kia customer, I expected a resolution or at the very least a clear commitment to investigate this issue. I am requesting that Kia: Document this as an official safety complaint. Inform me if there are any existing Technical Service Bulletins, engineering reviews, or pending design changes related to this issue. Provide an explanation of how Kia intends to address this safety concern for current and future Telluride owners and particularly to me as I have a 2 year lease. I am also submitting this report to the National Highway Traffic Safety Administration (NHTSA) so it is on record for investigation. Photos and video of the defect can be provided upon request. Thank you for your prompt attention to this serious safety matter. Sincerely, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
