Supplier discovered a fractured park pawl after completing a sever portion of their test course. If the park pawl is fractured, it could result in a false park. This could potentially impacts MT50e Walk-in vans built during the Pre-series phase of production. NOTE:  Identify by body style or type. – MT50e, electric walk-in van Basis for Determination of the Recall Population: At the current time, all MT50e electric walk-in vans built during the pre-series phase, with start dates October 18, 2021 to April 11, 2022 are included in the recall population. However, as DTNA continues to investigate, the population may be decreased. The supplier of the E-Axle notified DTNA of the specific part with a potential defect. Number potentially involved: 16 Estimated percentage of involved with defect: 100% Defect / Noncompliance Description For this Defect/Noncompliance: Describe the defect or noncompliance: MT50e electric walk-in vans are equipped with a DANA E-Axle with an internal spring holding the park pawl. Out of an abundance of caution, the supplier, while conducting product validation testing, discovered that after a severe portion of their test course, that a parking pawl was fractured. After the test results, the supplier tested again, at a lower speed, and discovered galling and damage to the pawl at the engagement site. A broken or damaged pawl could potentially result in the vehicle being set to park but roll away without the drivers intent if the parking brake is not set, contributing to an increased risk for crash or injury. Describe the safety risk: Failure mode could result in an unintended vehicle roll away if the parking brake is not set. Identify any warning which can precede or occur: Suspected potential for noise or feel from supplier statement, but not guaranteed and may be indistinguishable. Driver may also notice an absence of engaging gear sound from parking brake (actuation sound would still be present), but this is not guaranteed, would require drivers attention to small details.

Out of an abundance of caution, the supplier, while conducting product validation testing, discovered that after a severe portion of their test course, that a parking pawl was fractured. After the test results, the supplier tested again, at a lower speed, and discovered galling and damage to the pawl at the engagement site. A broken or damaged pawl could potentially result in the vehicle being set to park but roll away without the drivers intent if the parking brake is not set, contributing to an increased risk for crash or injury. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Failure mode could result in an unintended vehicle roll away if the parking brake is not set. Description of the Cause : NR Identification of Any Warning that can Occur : Suspected potential for noise or feel from supplier statement, but not guaranteed and may be indistinguishable. Driver may also notice an absence of engaging gear sound from parking brake (actuation sound would still be present), but this is not guaranteed, would require drivers attention to small details.
