GM recalls vehicles with defective fuel system parts

 

Warren, Mich. – June 27, 2018 – General Motors has recalled almost 850 vehicles potentially equipped with defective fuel system components, according to documentation submitted to the National Highway Transportation Safety Administration. The campaign affects vehicles across multiple brands, including:

  • 2018 Buick LaCrosse sedans produced March 27, 2018, and April 20, 2018.
  • 2018 Cadillac ATS sedans produced March 20, 2018.
  • 2018 Chevrolet Equinox sport utility vehicles produced between March 26, 2018, and April 20, 2018.
  • 2018 Chevrolet Colorado pickup trucks produced March 22, 2018, and April 27, 2018.
  • 2018 Chevrolet Malibu sedans produced between April 19, 2018, and April 27, 2018.
  • 2018 GMC Arcadia sport utility vehicles produced between April 5, 2018, and April 23, 2018.
  • 2018 GMC Canyon pickup trucks produced between March 23, 2018, and April 24, 2018.

GM suspects all of the vehicles referenced in the recall contain the defective components.

The Defect

Affected vehicles contain high-pressure fuel pump’s whose housings are not properly welded nearby flanges. These faulty welds could crack over time, resulting in fuel pump flange separation. Should this occur, the pump may oscillate within the engine compartment, leading to fuel leakage and, in some cases, fire. This defect therefore poses a serious risk to owners. However, GM has yet to receive field reports connecting the problematic parts to any accidents or injuries.

Timeline of Events

On April 25, 2018, Robert Bosch LLC, the vendor that supplied the fuel pumps installed in the recalled vehicles, contacted GM to disclose the potential existence of problematic housing and flange welds. The American automaker opened an official investigation into the issue May 5, 2018. While this inquiry uncovered zero occurrences of fuel leakage, GM determined, via Bosch engineering analysis, that the faulty fuel pump welds could fracture and lay the groundwork for this dangerous outcome.

Members of the GM Safety Field Action Decision Authority conducted a final review May 24, 2018, and determined that a voluntary safety recall was necessary.

GM notified dealers of the impending action May 31, 2018.

The Solution

The car manufacturer has yet to develop a workable solution, according to an FAQ document. There is therefore no timetable for owner notification. However, GM is working with Bosch to create a cost-free fix. Owners in need of assistance prior to the start of the recall can connect with GM customer service personnel by calling (866) 522-9559. Individuals in possession of recalled vehicles can also reach out to the NHTSA directly using its Vehicle Safety Hotline at (888) 327-4236.
