Detroit, Michigan – General Motors is recalling about 5,000 heavy-duty Chevrolet Express and GMC Savana passenger and cargo vans, and halting their production and sale until a fix for a suspected faulty alternator can be determined.

Relatively few of the affected vans were sold to retail customers; about 1,300 are in rental or other fleets. Owners of the affected vans are being urged to stop driving the vans, park them outside away from buildings and other vehicles and, if possible, disconnect both battery cables.

The affected vans were built in February and March of 2010. They include 2010 Chevrolet Express 2500 and 3500 vans with the last eight digits of their vehicle information numbers falling between A1129327 and A1142523; and 2010 GMC Savana 2500 and 3500 vans, made during the same period, between A1128784 and A1901915.

Only the 2500 and 3500 series vans are affected; light-duty half-ton Express and Savana vans use a different alternator, and are still being built and shipped.

About 1,400 AC Delco aftermarket heavy-duty alternators are also affected by the recall, with part numbers 15200110, 15288861, 15263859 and 15847291. Customers who had a heavy-duty alternator replaced in February or March in a 2005 to 2010 heavy-duty Express or Savana van, or other 2005 to 2009 GM truck or SUV are also asked to check their sales order receipts to determine if a suspect part was involved. If it was, or if the part used is unknown, they are also urged to stop driving the vehicles, park away from buildings, and if possible, disconnect both battery cables. These owners are asked to contact GM to provide their contact information so they can be informed when more information is available.
