Chevrolet Silverado, GMC Heavy-Duty Trucks Recalled for Gas Tank Issue

November 21, 2017 by Jerry Hirsch, @Jerryhirsch

General Motors is recalling about 35,000 Chevrolet Silverado and GMC Sierra 3500 trucks because of a problem with the fuel tanks in the vehicles.

The truck recall affects heavy-duty chassis cab-style trucks with dual fuel tanks from 2011 through 2015 model years.

The automaker said that if the front tank overfills, excess pressure could press it into the driveshaft and risk causing a leak. If fuel leaks onto a hot spot in the truck, a fire could start.

The problem is triggered when the low-fuel-level sensor for the front tank sticks, GM said.

Drivers could hear a knocking or grinding noise if an over-pressured fuel tank starts to contact with the driveshaft, GM said.

Owners will be asked to take their trucks to dealers. Technicians will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary.

GM plans to send recall notices to owners in December and then again in February. Owners can also contact GM customer service for Chevrolet (800) 222-1020 or for GMC customer service at (800) 462-8782. Owners asking about the recall should refer to GM’s identification number for it – 17399.
