NHTSA Service Bulletin 10209216: 2019-2021 Ford Bronco
Official manufacturer communication context for 2019-2021 Ford Bronco, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Some 2019-2021 Ranger vehicles built on or before 09-Aug-2021 and 2021 Bronco vehicles equipped with a 2.3L engine may experience reduced engine power in freezing temperatures with an illuminated malfunction indication lamp (MIL) and/or powertrain malfunction indicator (wrench) lamp with diagnostic trouble codes (DTC) P2111, P2112, and/or P2119. This may be due to water or ice buildup in the intake manifold behind the throttle body. If suspected, remove the throttle body and inspect for water or ice in the base of the intake manifold. If water or ice is found, replace the intake manifold with part number KB3Z-9424-B and crankcase vent oil separator hose, part number LB5Z-6A664-D. Refer to Workshop Manual Sections 303-01 and 303-08. For claiming, use causal part number 9424 and applicable labor times from Section 09 of the Service Labor Times Standard (SLTS) Manual.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
