Volkswagen and the National Highway Traffic Safety Administration have announced the recall of over 150,000 Tiguans over fuel issues. In the affected units, bubbles may form in winterized fuel that could cause the vehicle to stall. And “a vehicle stall,” says the NHTSA, “increases the risk of a crash.”
The issue could result from winter fuel that is warmed up, whether in warmer climates, hotter seasons or under “engine hot soak” – tech speak for when a cold fluid (whether a coolant, lubricant or fuel) sits in a hot engine block after it’s been shut off. Under such circumstances, deposits could collect in the fuel system, preventing proper circulation and causing the engine to stall shortly after ignition.
The recall affects 151,389 examples of the Tiguan manufactured between July 2007 and June 2014, covering the 2009 through 2014 model years. Volkswagen will notify owners to bring their crossovers in to their local dealership to have the software updated to increase fuel pressure so as to eliminate the bubble issue. The manufacturer reports, however, that no injuries have been reported as a result of such a malfunction occurring. See the notices from both VW and the NHTSA below for further details.
