VW recalls 151,000 SUVs for stalling

2014 VW Tiguan (VW)

Volkswagen AG said Saturday it is recalling 151,000 Tiguan SUVs in the United States for stalling problems.

In a notice filed with the National Highway Traffic Safety Administration, VW said it is calling back the 2009-2014 models because "gas bubbles may form in the fuel system when winterized fuel with high vapor pressures is used in warmer areas or months with higher ambient temperatures ... deposits may collect and degrade the electrical current flow inside the in- tank fuel pump leading to reduced fuel pump performance and pressure."

VW said the "fuel pump may not be able to overcome the vapor pressure under low loads and can potentially result in a vehicle stall directly after engine start, increasing the risk of a crash."

VW dealers will update the software and notify owners by Aug. 19.

VW said starting in February, increasing warranty rates were detected and internally reported prompting an investigation. In June, VW sent a technical bulletin to dealers to adjust software to increase fuel pump pressure preventing deposit formation.

VW notified NHTSA of the recall on July 21, but it wasn't made public by the agency until Saturday.
