Mercedes-Benz is recalling some 2016-17 Metris Vans following a federal safety probe into customer complaints of odor from leaking fuel hoses.
Gas leaking into the engine compartment could cause a fire if the fuel contacted a hot engine part, safety regulators said. The automaker is recalling 12,383 Metris vans that could have the problem.
Owners complaining about a gas odor inside the van after cold weather starting led the National Highway Traffic Safety Administration to open a preliminary investigation in March. The recall closes the investigation.
The fuel hose could leak at the lower connecting point of the transition hose or where the fuel line connects to the fuel pump. In both cases, only small amounts of fuel would leak.
No fires have been reported in the vans, according the NHTSA filing.
The recalled vans were assembled from March 2 to March 15, 2017. Two possible causes were listed for the defect: a fuel hose from a supplier that was later replaced, or the use of an incorrect tool to clamp the lower connecting point of the fuel hose.
The correct tool for the clamp assembly was substituted and the hose material for the upper joint area was changed in February 2017.
Mercedes-Benz dealers will replace the affected hose and clamp for free. The recall is expected to begin Jan. 25, 2019. The NHTSA recall is 18V-837.
