NHTSA Complaint #11666300 — 2021 FORD BRONCO SPORT

I am reporting a serious safety issue with my 2021 Ford Bronco Sport. The vehicle developed an internal AC leak due to a clogged AC drain. This leak caused water accumulation inside the cabin, leading to extensive electrical system failure, including loss of power steering, multiple warning lights, and a dead battery. The vehicle is no longer drivable. Upon researching online, I found that numerous other owners of 2021 Bronco Sports have reported the same clogged AC drain issue resulting in internal leaks and electronic malfunctions. This appears to be a systemic design flaw and should be investigated for safety recall consideration. I am submitting this complaint for documentation and to request that NHTSA review the frequency and severity of this failure, especially given the risk of electrical failure while driving. Component/System Failure: The air conditioning (AC) system drain became clogged, causing water to leak inside the vehicle cabin. This leak led to corrosion, mold/mildew buildup, and multiple electrical system failures, including loss of power steering, a dead battery, and numerous dashboard warning lights. The AC system and the resulting damage are available for inspection upon request. Safety Risk: The electrical failures caused by the leak created a serious safety hazard. Loss of power steering and critical electrical systems while driving could cause loss of vehicle control, increasing the risk of an accident. Additionally, mold growth inside the cabin poses health risks to occupants. Problem Confirmation: The issue has been confirmed by an independent service center that diagnosed the clogged AC drain as the root cause. Other 2021 Ford Bronco Sport owners have reported identical problems, indicating a widespread defect. Inspection by Others: The vehicle has been inspected by independent mechanics and the dealer service department. Ford corporate has been notified but has not acknowledged this as a recall or defect.
