Vehicles Affected: Approximately 1,558 model-year 2013 and 2014 Chevrolet Sonics
The Problem: Faulty fuel-tank strap welds could allow the strap bracket to separate, causing the fuel tank to rest on the exhaust pipe or plastic fuel-tank shield. If the fuel-tank shield and fuel-filler neck do not support the fuel tank, it may separate from the vehicle. If punctured and in the presence of an ignition source, a fire may occur. The automaker discovered the issue in the assembly plant and said there have been no customer complaints, crashes, injuries or fires resulting from the problem; most of the vehicles are in dealer stock.
The Fix: Dealers will inspect the bracket straps and make any necessary repairs for free.
What Owners Should Do: GM said motorists experiencing the problem may hear a rattling or scraping noise. Owners can call Chevrolet at 866-694-6546 or the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236, or go to www.safercar.gov.
