I was driving down the highway when my car just stopped running. Luck had it I wasn't on an interstate, thirty minutes later I would have been. (I'm a retired mechanic of 48 years. ) up on checking the car I found that there was no fuel pressure. Had the car towed to gm auto center in laramie, wy. I told the service writer that I presumed that the fuel pump had went out. When the tec. Ran diagnostics and a visual check they found that the fuel pump control module and fuse box were burnt. The tec. Told me that he had seen this before and showed me another fuse box with the exact damage. After returning home I was told by another mechanic that one of his customers had the same problem. This is a serious problem as all these items get melting hot and are located under the back seat just in front of the gas tank which is plastic and the seat is nothing but foam creating a serious fire hazard. I had the recall on the ignition switch done. After my experience with my car I think it was a smoke screen for the real problem the fuse box, fuel pump control module or fuel pump. No one wants to take this seriously. This all started on 09/25/2015 car millage 61855. I have the items in question.
