What is wrong
On certain trucks, a software problem could cause the fuel system to stop transferring fuel from the secondary fuel tank to the primary fuel tank. Additionally, the fuel gauge may indicate an incorrect combined fuel level. If this happens, you may not be aware of the low fuel level and the engine could stall. Note: This recall only affects certain 3500 HD models equipped with a gasoline engine and dual fuel tanks.
Why it matters
A sudden loss of engine power could increase the risk of a crash.
What the dealer will do
General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the engine control module software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.
