2023 Ford Bronco Sport ABS Module Leak

Posted on by

Ford will be asking the owners of certain 2023 Bronco Sports vehicles, to return to their dealerships to repair a problem that could lead to unexpected brake problems. Ford used supplier records to determine the population of affected vehicles in which the problematic Anti-lock Braking Systems (ABS) is installed. (Component Part Number: LX6C-2B373-LG)

In December 2022, Ford was contacted by the manufacturer of their ABS, about a quality issue affecting the Hydraulic Control Unit (HCU) of an Electronic Brake Booster (EBB). According to the defect report, a foreign object was introduced into the tool that assembles the Normally Closed (NC) valves used in the ABS Module. This object could create a “flat spot” damage to the ball which creates the seal. This damage could allow an unintended leak path through the valve. If the valve leaks, the driver may experience inconsistent brake pedal travel without warning. Additionally, the driver-selectable Auto Vehicle Hold feature may not operate as intended. The vehicle could creep unexpectedly after an auto-hold event is initiated.

Owners who receive notices will be asked to return to their dealerships to have the ABS module replaced. Ford’s number for this recall is 23S01 and the NHTSA campaign number is 23V-021.

This is the third recall affecting the 2023 Ford Bronco Sport. In November 2022, Ford recalled half a million 2020-2023 Escape and 2021-2023 Bronco Sport vehicles equipped with 1.5L engines. A fuel injector may crack and leak fuel inside the engine compartment and cause an under hood fire. (NHTSA Campaign Number: 22V-859)

In September, Ford recalled 2022-2023 Bronco Sport and 2022 F-150 vehicles because the parking lights may flicker during any of the three following scenarios. (NHTSA Campaign Number: 22V-859)

  • Scenario 1: When the customer manually selects the “position lamp on” mode.
  • Scenario 2: When the customer manually selects “Headlamp On” Mode.
  • Scenario 3: When the customer is driving in automatic headlamp mode, and the environment gets dark enough to trigger “Night Mode”, which turns on the headlamp and parking lamp function.

Volvo Vehicles Could Experience Loss Of ABS And ESC

Posted on by

Certain 2023 Volvo automobiles could experience a diagnostic error in the Brake Control Module 2 (BCM2) that could cause a loss of the Anti-lock Brake System (ABS), Electronic Stability Control (ESC), and traction control.

The vehicles affected include:

2023 Volvo C40
2023 Volvo S60
2023 Volvo V60
2023 Volvo V60CC
2023 Volvo V90CC
2023 Volvo XC40
2023 Volvo XC60
2023 Volvo XC90

Volvo first became aware of this condition in October 2022 when they received the first report of issues with the brake pedal in a 2023 Volvo vehicle. As reports increased, an investigation was opened to find a possible common root cause. In December the investigation was escalated to the Critical Concern Action Process (CCAP) and the Critical Concern Management Team (CCMT) initiated a technical investigation to evaluate the risk assessment and root cause. In January the technical investigation was completed and a recall was initiated.

According to the defect report, certain diagnostic tests that check the grounding of the BCM2 could put it in a faulty state that could result in a loss of brake support functions. The problem is caused by a lack of robustness in software compatibility with a specific BCM2 HW version.

The customer may experience a hard/stiff brake pedal and potential loss of brake support functions such as:

  • Brake-by-wire.
  • ABS, ESC, and traction control.
  • ACC (Adaptive Cruise Control), Pilot assist and OPD (One pedal drive)
  • All active safety and city safety functions described in the user manual that involve braking.

The driver display will warn the customer with DIM messages and malfunction indication lamps if this issue occurs. This is an intermittent issue, and the faulty state will remain through the drive cycle until the vehicle enters deep sleep.

Volvo will release an over-the-air (OTA) BCM2 software update to correct the problem. Volvo Car’s number for this recall is R10217 and the NHTSA campaign number is 23V-012.

Mercedes Benz AMG G63 and G550 ABS/ESP Warning

Posted on by

Mercedes Benz will be contacting the owners of certain 2019-2020 AMG G63 and G550 vehicles because they could contain a differential locking module control unit that does not meet the current production specifications.

According to the defect report, a resistor on the board could be affected by the sulfur fumes from the axle oil. If the resistor is impaired, the electrical current could increase and cause communications between the control unit and the locking actuator to be shut down. Both ESP and ABS system would be deactivated, increasing the risk of a crash under certain conditions. Drivers will be alerted of a problem through an illumined ABS and ESP message in the instrument panel.

Dealers will inspect the differential locking modules and replace them as necessary. The NHTSA Campaign Number for this recall is 20V-090.

2017 Mercedes Metris ABS Warning & Brake Noises

Posted on by

Daimler has determined that certain 2017 Mercedes Benz Metris vans may have been manufactured with front axle bearing retaining rings that were not seated correctly. The retaining rings could extend from the steering knuckles allowing the wheel bearing to move out of position. The problem could result in an ABS sensing error warning on the instrument panel, unfamiliar brake noises, unpredictable drive-ability and the loss of a wheel.

Those receiving notices will be asked to return to their dealers to have the front axle wheel bearing retaining rings inspected and correctly positioned as necessary. Owners wanting more information about the defect can contact Daimler customer service at 1-877-762-8267.
