“The hood cover is loose and rattles when driving. It makes me afraid as I drive the interstate everyday and it seems as if it is going to fly off. I also lose power or it fails to start due to some type of electrical issue, brakes go, steering goes and all lights on cluster light up”
NHTSA complaint #11183378, filed 2019-03, 80,000 miles“I have owned this truck since 2009, and it seems to be a common problem with the sunroof drain tubes clogging. When my vehicle was under warranty, and was going in for it's scheduled pmis I would have them blow the drain tubes out with air, but the clogging is now becoming more frequent, and the water if not removed can cause havoc with the cloth, electrical & flooring. Last week I had a mildew smell because of all the rain we have had, and the water built up in the sunroof drain area. …”

There is drain tubes in the corners of the sunroof this water is supposed to go do these tubes then on the ground. How ever this is not the case. In most cases the water leaks down the pillars in the trucks dash compartment and soaks the carpet on both sides and the head liner. We have had it to the dealership on several accessions and they just say they were stop up but they just leak the next day like nothing has even been done. They charge 300 dollars to do this. …”

NHTSA complaint #10413220, filed 2011-07, 93,356 miles“I own a Hummer H3 2006 model. I purchased it brand new. No accidents. The roof pools water because of a faulty drainage system. The water then comes out through the roof in large amounts and through the side walls and emergency brake. This can cause an accident due to the large amounts of water spilling onto the driver, or an electrical fire or mechanical malfunction. It can also cause mold in the interior due to large collections of water stagnating. This is a known issue that is recorded in GM forums - yet there is no recall for the faulty drain pipes.”
