Daimler Vans USA Recalls 7,400 Metris Vans over Loose Transmission Bolts

June 19, 2018 by Clarissa Hawes

Daimler is recalling more than 7,400 2015 through 2017 Mercedes-Benz Metris vans for concerns about loose transmission support mounting bolts.

The screw connection of the transmission carrier to the vehicle body may not be tightened with the specific torque, according to a memo from Daimler to dealers. If the screw connection is not tight enough the bolts could loosen causing the transmission to lose connection with the vehicle.

If the bolt loosening were to occur, the position of the transmission and the angle of the propeller shaft of the transmission could change. If it exceeded a certain degree, the joint disc could incur damage.

Daimler says that warning signs include significant rattling noises under the vehicle as well as vibrations caused by the increased flexing of the propeller shaft.

If drivers ignore the sounds and continue to operate the vehicle, an abrupt loss of power could occur.

In this case, steering and braking would not be affected and the vehicle would remain controllable, according to Daimler.

However, a spokesperson from the National Highway Transportation Safety Administration said the agency concluded that such damage to the driveshaft could cause a subsequent loss of power to the wheels, increasing the risk of a crash.

If a problem is found, dealers will replace and tighten the transmission support mounting bolts at no cost to the customer. The fix is expected to take less than 1 hour.

Customers will be notified via mail in at the end of July.

The affected vehicles were built in the company’s Charleston, N.C., plant. The Metris vehicles still in the factory were immediately inspected and evaluated as fault-free after detection of the issue, according to Daimler.

The cause of the loose bolts was determined to be an individual employee that did not tighten the screws sufficiently. Daimler is now evaluating the introduction of an electronically monitored screwdriver at the corresponding station.
