SSM 501312021-09-28. Service bulletin. POWER TRAIN; ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Some 2021 Bronco Sport vehicles may exhibit a hiss or rattle noise in the engine compartment while driving which may be originating from the manual park release cable. Disconnect the cable from the transmission and road-test to confirm the noise is eliminated. If the noise is still present, refer to Workshop Manual (WSM), Section 100-04 for diagnostic and repair information. If the cable is causing the noise, reconnect the cable and inform the customer that Ford is working on a solution which is expected to be available by mid-December 2021. Advise the customer that the vehicle is safe to drive and schedule a follow-up appointment for mid-December. Once the solution becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for updates.
SSM 499962021-09-04. Service bulletin. ENGINE AND ENGINE COOLING. Some 2021 Bronco Sport vehicles equipped with a 1.5L EcoBoost engine may exhibit a no crank/no start start condition with an illuminated malfunction indicator lamp (MIL) and one or more of the following diagnostic trouble codes (DTC): P093B, P2282, P0420, P062B, P21D1, P21D0, P21CF, P0710, and/or P0712. This may be due to a damaged wiring harness at the transmission cover. If damage is found, repair as necessary. Refer to Wiring Diagram Cell 005.
SSM 499302021-08-02. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Some 2020-2021 Escape and 2021 Bronco Sport vehicles equipped with the 1.5L engine may exhibit a lugging vibration and/or boom noise while driving in gears 5-8 at approximately 1500 engine revolutions per minute (RPM). This may be felt more when the engine is under a light to moderate load. A vibration and/or boom noise could be generated from the firing frequency of the 3 cylinders or when cylinder deactivation occurs and the engine is running on 2 cylinders. Compare to a like vehicle before attempting to diagnose as this condition may be characteristic. Setting the vehicle's drive mode to SPORT may eliminate the condition by changing the shift points of the transmission. Refer to the Owner's Manual for information on drive mode control and how to select them.
SSM 499242021-08-02. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. Some 2019 MKC, 2019-2021 Edge/Nautilus/Escape/Ranger/Explorer, 2020-2021 Corsair, and 2021 Bronco Sport vehicles equipped with 2.0L and 2.3L EcoBoost engines may exhibit a light to moderate ticking type noise at idle (600-700 RPM). The noise is usually more prominent in the area of the high-pressure fuel pump, located on the top of the engine just behind the number 4 ignition coil. This noise is not detrimental to engine function and has no short or long-term effects on engine durability. This an operating characteristic of these engines and no repairs should be attempted.
