# Service bulletin TSB 23\-2041

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10232491
- Published by NHTSA: 2023\-03\-04
- Manufacturer's number: TSB 23\-2041
- Manufacturer's date: 2023\-02\-08
- NHTSA component: SERVICE BRAKES; POWER TRAIN

## NHTSA's summary

Some 2020\-2022 Escape vehicles built on 1\-Nov\-2020 and through 29\-Aug\-2022 and 2021\-2022 Bronco Sport vehicles built on or before 23\-Sep\-2022 may exhibit a moan noise when the vehicle is driven in reverse \(R\) in cold weather and/or high humidity. This may be due to the suspension sensitivity of the vehicle and interaction of the caliper housing with the pad backplate. To correct this condition, follow the Service Procedure to replace the rear caliper bushings.

## Other bulletins for the same vehicles and component

- [SSM 55221](/bulletins/11038438.md), 2026-10-12, Service bulletin: UNKNOWN OR OTHER; POWER TRAIN; ELECTRICAL SYSTEM. For 20222026 vehicles equipped with a 8F35 transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, Section 307\-01 \> Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements \(N\>R, N\>D, R\>D, and/or D\>R\) should be noted in the warranty claim. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.
- [TSB 26\-2328](/bulletins/11035099.md), 2026-07-20, Service bulletin: POWER TRAIN; UNKNOWN OR OTHER. This bulletin supersedes 26\-2194. Reason for update: update the Parts list to correct a part description " Loctite 638", update the claim quantity for the drain/fill plug, update the claim quantity of the wheel hub bolts \(Corsair\) and limited the parts list for Edge/Nautilus to only the rear drive unit fluid. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Shudder chatter condition, most noticeable at low speeds turning No relevant diagnostic trouble codes \(DTCs\) present This may be due to internal rear drive unit \(RDU\) fluid contamination.
- [SSM 54939](/bulletins/11034017.md), 2026-06-22, Service bulletin: POWER TRAIN. Some 2020\-2026 Corsair/Escape, 2021\-2026 Bronco Sport, and 2022\-2026 Maverick vehicles equipped with an 8F35 transmission may exhibit a shudder condition, most noticeable at speeds below 60 mph \(100 km/h\), with no relevant diagnostic trouble codes \(DTC\) stored in the powertrain control module \(PCM\). Sometimes, this may be perceived/felt as an engine misfire. This may be due to the torque converter. If Pinpoint Test K: Torque Converter Clutch Operation in Workshop Manual \(WSM\), Section 307\-01 \> Diagnosis and Testing \> Diagnosis by Symptom directs to replace the torque converter, remove and replace the torque converter and torque converter seal. Refer to WSM, Section 307\-01 \> Removal and Installation \> Torque Converter Seal. Remove the main control valve body.

This may be due to an open circuit on circuit SBB05 and/or a damaged splice S133. Before performing the pinpoint test for P04CA in Workshop Manual \(WSM\), Section 310\-00, inspect circuit SBB05 and splice S133 for damage such as an open circuit. Repair as necessary. Refer to Wiring Diagram, Cell 005. If no damage is found, refer to WSM, Section 310\-00 for normal diagnostics. For claiming use causal 14290 and labor operations 12650D, 12650D45, and 12650D45WR.
