Concerns:

Hexagon clamping nut M12 x 1.5 on various threaded connections on the chassis

 

Information:

There is a possibility that clamping nuts, on which the thread was not manufactured according to specifications, were installed on various threaded connections on the chassis on the affected vehicles.

As a result, the required tightening torque was reached before the threaded connection was actually tightened fully when installing the clamping nuts. There is therefore no guarantee that the affected threaded connections will remain sufficiently tight over the service life of the vehicle.

 

Action required:

Rework threaded connections on the front and rear axle.

On vehicles that have already been delivered to customers, the screwed components must also be checked for damage.

 

Information

Please note that different screw positions on the front and rear axle must be reworked on the affected vehicles.

The following specific campaign scopes have therefore been defined for reworking the threaded connections. Every vehicle is clearly assigned just one campaign scope.

The relevant M12 x 1.5 fastening nuts must be replaced on all affected vehicles, depending on the assigned scope.

In addition, the relevant fastening screws must also be replaced.

On vehicles on which a component is screwed at the relevant screw point (e.g. actuator or connecting link), depending on the assigned scope, the thread on the relevant component must be checked and the component may also have to be replaced, depending on the result of the check.

On vehicles that have already been delivered to customers, the components that are screwed together must also be checked for damage caused by relative movements while driving as installings, contact surfaces or bores on the individual components may have been damaged. The relevant components may also have to be replaced, depending on the result of the check.

IMPORTANT REMINDER

IT IS A VIOLATION OF FEDERAL LAW FOR DEALERS TO DELIVER TO CUSTOMERS NEW VEHICLES IN THEIR INVENTORY AFFECTED BY THIS NOTIFICATION UNTIL THESE VEHICLES ARE REMEDIED.

DEALERS SHOULD NOT SELL, LEASE, RENT, OR LOAN ANY NEW OR USED VEHICLES IN DEALER INVENTORY AFFECTED BY THIS NOTIFICATION PRIOR TO REMEDY. DEALERS GROUNDING LEASE RETURNS SHOULD REMEDY ALL AFFECTED GROUNDED VEHICLES. Undelivered Vehicles (WMC1)

 

Please be advised that Stop Delivery Campaign WMC1 has been expanded to include sold/delivered vehicles in customer hands as Safety Recall AMA3.

 

WMC1 vehicles have been rolled into the AMA3 recall population, and must not be delivered until remedied. Remedy availability is expected in early April.

 

Overview

There is a possibility that locknuts that were not manufactured to specification were used on diverse threaded connections of the vehicle’s suspension.

As a result, the specified tightening torque may not have been met on the threaded connection and therefore cannot be guaranteed over the service life of the affected vehicles.

The locknut and the corresponding bolt at the relevant connections will be replaced and torqued to specification.
