Owners of 2010 Chevrolet Express and GMC Savana 2500 and 3500 models should park their vans away from buildings and other vehicles and disconnect the battery because of a serious risk of fire. GM announced today that the alternators used in the heavy duty vans can cause a fire in the vans and a recall and stop sale have been ordered. According to Autoblog, the stop sale means that any of the 2010 GM heavy duty vans recalled that have been sold to rental agencies cannot be rented to customers.

Chevrolet Express and GMC Savana 1500 owners should not be alarmed. Their vans are safe and use a different alternator. Likewise, any older GMC Savana and Chevrolet Express 2500 and 3500s are unaffected by the recall.

Any owner of a 2005 through 2010 GM van, SUV or truck who had their alternator replaced should check their work order to see if AC Delco part numbers 15200110, 15288861, 15263859 or 15847291 were used. If any of those parts were installed, or the work order doesn’t specify which alternator was used as a replacement part, owners are instructed to park the vehicle away from anything flammable and remove the battery cables.

GM says that it will contact owners of any affected vans as soon as the company has devised a fix for the faulty alternator. Until then, there are about 5,000 vans that have been sold to customers and rental agencies nationwide that are now unable to be driven.
