Meritor Wabco: equipment recalls

1. 21E025000Received 8 Apr 2021. 2,918 units.

   Service Brakes, Air / Disc / Chamber

   Defect, in the NHTSA record

   Meritor, Inc. (Meritor) is recalling certain TSE T2024 Air Chamber Part Number D3 3376T20. The spring brake chamber may have been assembled with incorrect springs that were out of specification, which can cause the pressure plate to shift.

   Consequence, in the NHTSA record

   The pressure plate may tear the diaphragm, causing a loss of air pressure, and increasing the risk of a crash.

   Remedy, in the NHTSA record

   Meritor will notify the affected vehicle OEMs and will inspect the pressure plate and replace brake chambers where the pressure plate has shifted, free of charge. Owner letters were mailed May 10, 2021. Owners may contact Meritor customer service at 1-866-668-7221.

   Products named: Meritor Wabco Air Brake System.

   Report filed by Meritor, Inc.. Owner notification date in the NHTSA record: 10 May 2021.

2. 14E006000Received 5 Mar 2014. 34 units.

   Parking Brake

   Defect, in the NHTSA record

   Meritor Wabco Vehicle Control Systems (Meritor Wabco) is recalling certain trailer spring brake control valves sold as replacement parts with dates codes ending in 0113 through 1113. The affected spring brake control valves (SBCV) have an intake/exhaust valve which may come apart and prevent the parking brake from engaging.

   Consequence, in the NHTSA record

   If the trailer parking brakes do not engage, an unattached trailer could unexpectedly roll away, increasing the risk of a crash or injury to those nearby.

   Remedy, in the NHTSA record

   Meritor Wabco will notify owners, and dealers will replace the spring brake control valves, free of charge. The recall began in April 7, 2014. Owners may contact Meritor Wabco at 1-248-435-8001.

3. 11E039000Received 3 Oct 2011. 10,700 units.

   Electronic Stability Control (ESC)

   Defect, in the NHTSA record

   Meritor wabco is recalling certain electronic stability control (ESC) modules with part numbers 446 065 020 0, 400 850 179 0, 400 850 195 0, 446 065 027 0, and 400 850 185 0, shipped to a variety of north american vehicle manufacturers from august 2005 through september 2011. Under certain road and driving conditions, vehicle body roll and road inclination characteristics may adversely affect the slip angle calculation of the electronic stability control (ESC) system. This might cause the ESC to perceive an over steering situation and therefore apply the outer wheel brake on the front axle until the vehicle is perceived to be stable.

   Consequence, in the NHTSA record

   If the driver is slow to react during this ESC intervention, the vehicle may deviate from the intended line of travel, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Meritor wabco is working with the vehicle manufacturers to identify and notify vehicle owners of the recall. Owners may contact meritor wabco at 1-248-435-8001 or their vehicle manufacturer.

   Products named: Meritor Wabco Esc.

   Report filed by MERITOR WABCO VEHICLE CONTROL SYSTEMS. Owner notification date in the NHTSA record: 5 Oct 2011.

4. 09E032000Received 19 May 2009. 1,021 units.

   Steering

   Defect, in the NHTSA record

   Meritor wabco is recalling 1,021 steering angle sensors (sas), p/nos. 444 120 004 0, 400 850 647 0, and 400 850 666 0, with serial numbers below 3404 which were shipped as original equipment for use in motor coaches and emergency vehicles between july 2007 and february 26, 2009. Internal friction can develop between the sensor gears and the sensor housing as a result of external forces experienced on the vehicle including vibration. If developed friction is great enough, the driving tab of the sas can sheer as the driver turns the steering wheel.

   Consequence, in the NHTSA record

   With a broken sas driving tab, the electronic stability control (ESC) will not function properly, which could possibly result in a vehicle crash.

   Remedy, in the NHTSA record

   Each vehicle manufacturer will provide a remedy plan and notification schedule. The affected vehicles will be repaired without charge to the owners. Owners may contact their vehicle manufacturer or meritor wabco at 1-859-525-3676.

   Products named: Meritor Wabco Steering Angle Sensor.

   Report filed by MERITOR WABCO VEHICLE CONTROL SYSTEMS. Manufacturer campaign number C9AB. Owner notification date in the NHTSA record: 17 Jul 2009.

5. 02E059001Received 13 Nov 2002. 1,985 units.

   Service Brakes, Air / Controls / Hand Control/Valve

   Defect, in the NHTSA record

   Manifold dash valves with push to connect fittings used to control the park brake function on trucks and trailers with air brakes and are identified with a manufacturing date code of 001a1k through 330a1k manufactured between january 1 and september 30, 2002. The date code is stamped into the back of the valve body. The park knob can pop out unexpectedly while the vehicle is in motion. This will exhaust the air from the park brake system on the trailer and apply the parking brakes.

   Consequence, in the NHTSA record

   If this condition is not noticed, the driver could lose control of the vehicle, possibly resulting in a vehicle crash.

   Remedy, in the NHTSA record

   Meritor wabco will notify its customers and make arrangements to have the valve inspected and, if necessary, replaced free of charge. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact haldex brake systems at 816-801-2641.

   Products named: Meritor Wabco Manifold Dash Valve.

6. 01E062000Received 12 Dec 2001. 21,600 units.

   Service Brakes, Air / Supply / Check Valve

   Defect, in the NHTSA record

   Equipment description: meritor wabco pneumatic anitlock brake system (ABS) valve packages produced between september 3 and october 26, 2001. The bolts used to assemble steer and drive axle ABS valve packages together and a traction control valve inlet fitting were torqued below specification.

   Consequence, in the NHTSA record

   Bolts torqued below specification will not reliably prevent air leakage at the affected ABS valve package interface joints once the component begins normal vehicle operation. If air leaks develop at any of the ABS valve package interface joints, brake system pressure reductions could occur during braking or normal operation with units equipped with the traction control option, potentially extending stopping distances, possibly resulting in a vehicle crash.

   Remedy, in the NHTSA record

   Owners will be notified to have their vehicle repaired free of charge at an authorized dealer. Owner notification began january 14, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact meritor wabco at 859-746-5956.

   Products named: Meritor Wabco Abs Valve Package.

   Report filed by MERITOR WABCO. Owner notification date in the NHTSA record: 14 Jan 2002.

7. 00E055000Received 15 Sep 2000. 14,730 units.

   Interior Lighting

   Defect, in the NHTSA record

   Equipment description: phase 1, d-version antilock brake systems (ABS) manufactured from october 1, 1997, through november 30, 1999 with part nos. 446 044 071 0, 446 044 072 0, 446 109 000 0, and 446 109 001 0, installed on medium trucks, school and transit buses, and motor homes greater than 10,000 lds. Gvwr. The phase 1, d-version hydraulic ABS may not detect an extreme wheel speed sensor air gap that can be created by placing the sensor a significant distance from its intended position when the vehicle is stationary. Therefore, the ABS does not comply with federal motor vehicle safety standard 105, "hydraulic and electric brake systems."

   Consequence, in the NHTSA record

   An extreme wheel speed sensor air gap that affects the generation of a response signal may not be detected and thus the indicator lamp may not activate.

   Remedy, in the NHTSA record

   Meritor wabco will contact the affected vehicle manufacturers and request that they notify vehicle owners to have the phase 1 d-version ABS ECU either reprogrammed or replaced.

   Products named: Meritor Wabco Abs Indicator Lamp.
