Water Pump problems of the 2006 GMC Envoy

Gas sending unit/fuel pump lines rot out due to corrosion and spray gasoline all over the underside of vehicle. The vehicle might stall but often times it keeps running, all while spraying gasoline all over the place. This one does not even trip a check engine light while running in this condition. The only warning was the smell of gasoline- some people do not have a sense of smell, and this could have been very dangerous. This is a fire waiting to happen. This corrosion issue is known to gm, why is this not a safety recall? this let loose on my sister in-law while driving, it could have resulted in explosion or serious fire. Gm knows that these rot out prematurely due to poor materials and combined with road salt and environmental effects in snow states. This vehicle also suffers from the driver door switch for door locks and windows not always working, due to shorting out from water. . . Again a known issue with "some" units of this year, but this has not been recalled on this particular "unit" yet. Some of these have shorted out and caused fires- combined with the leaky gas sending units, this is a serious safety hazard. Do not park this vehicle in a garage- a fire waiting to happen. . . Come on- make gm take care of these problems before someone gets killed. This truck was at a dealer for the fuel leak, they told her it needs a sender unit and a bunch of other things that have failed on this poorly built truck, which include wheel bearings, abs sensors. Steering wheel sensor (? really) inop door locks, leaking fuel, water pump leaking, failing headlights- that work when they want, and a whole bunch of other repairs. This fuel and electrical issue(s) should be immediately recalled. This is affecting a lot of people who live in the northern states with snow and salt on the roadways.
