Recall 25V099/SC336 was not performed on my vehicle when it was in the dealership. My vehicle is now disabled at Capitol Kia San Jose with complete engine failure. They are denying any responsibility and refusing repair coverage. I have written a formal letter to Kia Corporation requesting an immediate review of my vehicle. With this being an NHTSA recall I am hoping to get some intervention somewhere regarding this situation.

I am filing this complaint to report a serious safety failure involving the service braking system and the failure of Forward Collision‑Avoidance Assist (FCA) and Automatic Emergency Braking (AEB) on my 2021 Kia Soul. During an imminent collision event, the vehicle failed to brake as expected, and FCA/AEB did not activate, despite conditions that should have triggered emergency braking. This created an extremely dangerous situation and placed me and other motorists at risk of serious injury or death. The vehicle is currently subject to an active recall and has now been inoperable at the dealership for approximately one month under the lemon law process. The failure involved federally regulated safety systems, not supplemental or convenience features. I reported this incident to Kia America Customer Care, but the manufacturer has declined to conduct a manufacturer‑level safety investigation unless I personally pay for removal and shipment of the ACU/Event Data Recorder (EDR). Kia America has also declined to provide any transportation assistance while the vehicle remains unsafe and inoperable and has referred the matter back to the dealership and my insurance instead. Kia America has stated in writing that they rely solely on dealerships for diagnosis and repair and that they will not investigate further unless I incur additional costs. This refusal to independently investigate a braking system failure raises serious safety concerns, particularly given the potential risk to other drivers if this defect is not addressed. Due to the prolonged loss of use of the vehicle, I am experiencing significant financial hardship and risk to my employment, as I can no longer afford a rental vehicle. I am submitting this complaint so that NHTSA is aware of a potential defect involving brake system failure and non‑functioning collision‑avoidance systems on this model.

Manufacturer defect: Massive paint delamination/adhesion failure on the roof. Large sheets of paint are flaking off while the vehicle is in motion, creating a debris hazard for following drivers and distracting the operator. The failure has exposed the bare metal structure, which may lead to premature rusting.
