Official summary
Some 2025 Bronco Sport/Transit vehicles equipped with R-134a refrigerant systems may exhibit a concern of the air conditioning (A/C) blowing warm with a leak detected at the low side service port. This may be due to a concern with the low side service port cap clearance causing the service port valve to open slightly when the cap is fully seated. To correct the condition, discard the old service port cap and service port valve. Install a new service port valve, recharge the system, and install a new low side service port cap using part number DS7Z-19D702-B. For claiming, use causal part 19D702
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
