Ignition Switch problems of the 2001 Chevrolet 1500

I purchase my Chevrolet 1500 pickup new in 2001 and have maintained well. For no apparent reason, the on board computer warning light will indicate my fuel tank is empty and the fuel gauge needle will go to empty. The light and gauge will remain this way until I turn the vehicle off. At that time it may work or it may not. I currently have 72,300 miles on the vehicle. This occurrence began around 35,000 miles. I have had the vehicle into the dealer several times and their response has been that it doesn't happen when it is in the shop so they cannot do anything about it. I am concern with the current safety recalls with the ignition switch and the possibility that the impact bag may not deploy in an accident may also be an issue with my vehicle. I have not worried about this until the recent problems have been made public.

Nothing but problems with truck. First was the slip yoke in the drive shaft, felt like tranny was slipping from take off at start position. Replaced under warranty. Anti-lock brakes would come on with every stop. Usually at very slow speeds, causing truck to exceed 5-10 ft further than it should have. Had front wheel bearing replaced, fixed for some time doing it again. Also in the mean time, had to have all brakes and rotors replaced. Brake system is awful. This could cause accidents. Also, has cold engine knock, very loud knock, not a normal knock. Something isnt right with this. Done this since a little over 20,000 miles, worse when temperatures outside are low. Had to have 4x4 switch on dash replaced. Kept getting service 4wd unit. Out of warranty at this time. I know of at least 4 other with all same problems. Still nothing done with gm, something should be done. Especially with the brake system. Safety hazard.
