Was driving in the business district when pump failed. Engine shut down which also shut down power brakes and steering. Gas guage showed empty although tank was half full. Had to have the unit towed into dealership where pump was replaced at a cost of $1203.84. This was the second failure of the gas tank pump. First replacement was I believe in the fall of 2005 shortly after the warranty had expired at a cost of slightly less than $1000.00. Mileage would have been between 35 & 40,000. Don"t have the ticket for this but I believe I can get it. Have talked with others who have had the same problem. If you have pickup can be changed cheaper as they remove the pickup box. In both instances I was traveling at a low rate of speed so the loss of power steering and power brakes was not catistrophic.

Battery died, replaced. Battery lights coming on while driving the vehicle, unable to start vehicle, vehicle stalling. Unable to operate vehicle due to loss of power. This happened while driving 30 MPH in the rain. Barely able to pull vehicle off roadway. No power at all including lights and hazard lights. Took to chevrolet dealer - found no problem, nothing done to correct. Was told that after market alarm system (installed at chevrolet dealer) could be the cause of the problem. Took to audio installer and had alarm removed. Was told by different chevy dealer that they had the same problem right now with a tahoe in their shop. They removed alarm and have had no problems since (2 days). Would need to drive my vehicle to see if it happens again. This is a severe safety issue as it could easily result in an accident because oncoming vehicles can not see you without hazard lights. Old part is available. I have kept the alarm system if needed to review.
