Volkswagen Group of America is issuing two separate safety recalls – one for 2009-2014 model-year Tiguan SUVs and another for 2009 MY Routan minivans, according to the National Highway Traffic Safety Administration.

The Tiguan recall involves 151,389 SUVs manufactured from July 2007 to June 2014. When the vehicle uses winterized fuel, bubbles might form in the fuel system and lead to stalling.

Dealers will update the vehicle software to increase the fuel pump pressure and remedy the problem. There will be no charge for this service.

The Routan recall involves 18,526 2009 model-year minivans. The ignition switch in these vehicles might inadvertently move from the “run” position to the “off” or “accessory” position and deactivate vehicle safety systems, NHTSA said.

If the ignition switch moves from the “run” position, the engine can turn off and depower such safety systems as air bags, power steering and power braking.

The minivans were built by Chrysler, which recently issued recalls of its own to address ignition switch problems.

Volkswagen has previously recalled 2010-MY Routans for the same issue. A similar problem spurred General Motors’ ignition switch recalls.  

The problem is most likely to occur when the vehicle is traveling over rough road conditions, or when something else jars the key ring. Until dealer technicians make the needed ignition switch modification, Volkswagen is advising drivers to remove everything from their key ring except the car key. Any added weight on the key ring can increase the likelihood of the problem occurring.

The Routan recall is set to begin this month. There will be no charge for the ignition switch modification.
