Two pairs of Sister Trucks are being recalled by Volvo and Daimler in order to repair the fifth-wheel assembly in one pair and an overheating air conditioner in the other. One recall involves the 2004-06 Dodge Sprinter and the 2001 Mercedes-Benz Sprinter. Both are commercial delivery vans.

Transport Canada says the rear interior lights for both trucks are installed in the air conditioning ducts and that the lights can overheat causing the lens to distort and lead to a short circuit, which can start a fire. Dealers will replace the rear interior lamps with a modified version that contains lower wattage bulbs.

Volvo’s sisters are the 2007-08 Volvo VHD, VNL, VNM and VT models and the 2006-2008 Mack CHN, CL, CT, CTP and CV models. Volvo acquired the Mack line of trucks about 10 years ago. Those vehicles, says the recall division at Transport Canada, need some work on their fifth-wheel assemblies to prevent towed trailers from breaking away from the tractor.

A lever arm on the assembly may have been incorrectly installed during the manufacturing process. Its pivot bolt may have been overtightened, which could distort a spacer sleeve preventing the fifth-wheel latch jaw from latching securely around the Trailer king pin. Dealers will replace the pivot bolt and sleeve with a hex head shoulder bolt and washer.

Kawasaki is asking the owners of more than 5,000 of its motorcycles to make a stop at the dealer before putting the bikes up for the winter. The company is concerned that a bolt holding the muffler was insufficiently torqued at the factory and that it could loosen and allow the muffler to fall off the bike. Dealers will tighten muffler mounting bolts to the proper torque on the 2002-08 KLR 650 motorcycle.

Recall notices are mailed to vehicle owners and may take several weeks to arrive. If you do not receive a notice, contact a dealer.
