One problem related to other fuel system tank filling/charging has been reported for the 2004 GMC Sierra. The most recently reported issues are listed below.
Rusted out/ corroded brake lines burst while stopping for a deer running out on the road. Was warned of this problem upon purchase of the vehicle in 2010 and personally coated all brake lines b4 winter every year. . . Never saw worse lines! I own classic cars that are twice as old with shiney original brake lines. The fuel lines also rotted out spilling fuel over the top of the fuel tank and on the ground while filling up. All fuel lines and fuel pump connections were severely rotted. Worst I have seen. Dash consistently changes languages rendering odometer non functional. Speedometer is inaccurate some times not even working especially on cold days. Hmmmm rotted brakes+no speedometer+leaky fuel lines=crash,bang boom!. . And I have a car seat in my vehicle! luckly I perform preventative maintenance and drive safely. Still wonder how these issues got swept under the rug.
