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.

## Other bulletins for the same vehicles and component

- [LI27.19\-N\-079793](/bulletins/11023982.md), 2025-10-07, Service bulletin: POWER TRAIN. Complaint Transmission control unit Y3/8n4 \(fully integrated transmission control unit \(VGS\)\) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy For vehicles with 722.9 transmission: Ensure LI54.15\-P\-057373 is performed before replacing any component parts. After processing and complying with the above document\(s\): 1. Perform an ignition reset on Y3/8n4 \(VGS\) 2. Inspect transmission connector for loose connections, damaged wiring or pins and any other concerns. If communication with the VGS cannot be established, the complete valve body \('electrohydraulic controller unit \(EHS\)'\) must be replaced. Installation of a VGS repair kit is not permitted in this case as it is not possible to transfer the necessary valve characteristics without communication with the original control unit.
- [LI08.10\-N\-078545](/bulletins/11009854.md), 2024-11-05, Service bulletin: POWER TRAIN. Complaint: Noises when reversing slowly \<5 km/h \(squeaking\) Cause: There is a seal in the electric drivetrain that seals off the coolant system from the electric motor. This seal is moistened with coolant during forward travel. As a result of the change in rotational direction when reversing slowly, it may be the case that this sealing ring is no longer moistened. Squeaking noises may occur as a result of the so\-called "stick\-slip effect". This behavior does not impact the function or durability of the sealing ring and electric drivetrain. Remedy: Do not replace any parts. Explain the cause of the noises to the customer.
- [V\-RC\-2020070008](/bulletins/10180324.md), 2020-09-28, Service bulletin: POWER TRAIN:DRIVELINE:DRIVESHAFT. Propeller Shaft
- [Initial NCU \- 44](/bulletins/10177238.md), 2020-07-13, Service bulletin: POWER TRAIN:DRIVELINE:DRIVESHAFT; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Propeller Shaft Mercedes\-Benz AG \(“MBAG”\), the manufacturer of Mercedes\-Benz vans, has determined that on certain Metris vehicles from platform 447 \(VS20\), the propeller shaft may not be attached to the intermediate bearing according to the specification. If the propeller shaft is improperly attached to the intermediate bearing, over time damage to the propeller shaft joint could occur. The rotational imbalance of the shaft could lead to vibrations to the underbody of the vehicle, and to inaccurate signals to the airbag control unit. If improper signals are sent to the airbag control unit, the frontal airbags could inadvertently deploy, increasing the risk of injury to front occupants and increasing the risk of a crash.
