Nissan is recalling some 2012 NV vans because their air bag control units were assembled incorrectly and Mercedes-Benz is recalling some 2002 and 2003 Sprinter 2500 and 3500 vans for possible intake manifold corrosion.

2012 Nissan Altima, NV Vans

The Problem: Nissan is recalling some 2012 Nissan Altima sedans and NV vans because their air bag control units were assembled incorrectly. The units may have been wired incorrectly, which means the air bags may not properly inflate in the event of a crash. If the airbags do not deploy during a crash, the driver or passengers could be injured.

The Fix: Nissan will replace the airbag control unit free of charge, and will begin contacting the affected owners on August 22, 2011. Owners can call Nissan for more information at 1-800-647-7261.

Number of Vehicles Potentially Affected: 32 Nissan Altimas manufactured between June 15, 2011 and June 21, 2011, and 22 Nissan NVs manufactured between June 23, 2011 and June 28, 2011.

2002-2003 Dodge, Freightliner Sprinter

The Problem: Mercedes-Benz is recalling some 2002 and 2003 Sprinter 2500 and 3500 vans, which were sold under Dodge and Freightliner brands. Because the vans were sold and driven before the U.S. switched to Ultra Low Sulfur Diesel fuel, it can suffer from corrosion when using fuel with higher concentrations of sulfur. Exhaust gases passing through the Exhaust Gas Recirculation (EGR) system can corrode the intake manifold, which could lead to damage to the fuel return line and firewall around the manifold.

The Fix: Chrysler will notify Dodge owners, while Mercedes-Benz will notify those with Freightliner-branded vehicles. Dealers will replace the affected intake manifold for free. Owners can call Chrysler at 1-800-853-1403 or Mercedes-Benz's Sprinter division at 1-843-695-5031.

Number of Vehicles Potentially Affected: 665 vehicles, all hailing from the 2002and 2003 model years. Said vehicles were sold as the Dodge Sprinter 2500, Dodge Sprinter 3500, Freightliner Sprinter 2500, and Freightliner Sprinter 3500.
