Paint is peeling off entire vehicle causing significant rusting to the vehicle. See this problem on almost all GMC Savanna,and Chevy Express vans regardless of year. The paint starts peeling off in huge chunks on the hood. The rusting on the roof is the worst, it holds water on the roof seams, the paint starts peeling and rust starts. After the paint peels off the primer fades off in about a day or two. It seems that there was a lack of paint hardener in the paint. I think GMC should fix it for free cause this is a problem on all GMC Savanna and Chevy Express vans.
