I have a 2003 GMC Sierra 1500. When turning at low speed at times the power steering goes out for a few seconds then comes back. Yesterday I almost hit a car head on due to this problem. I was turning into a gas station and the steering went out. A car was pulling out of the station as I was pulling in and the power steering went out. I was going straight at and I struggled through it to make the truck turn. If my wife would have been driving the truck, there would have been an accident. This needs to be recalled and fixed before someone gets killed. This has been going on for the last 6 months but yesterday was a close call.

I previously had to have the power steering cooler replaced because of leaking corroded lines. Just recently had to have trans cooler replaced because of leaking corroded lines. Mechanic said all lines underneath (brake, steering, etc) are terribly corroded and we will definitely pay attention to all corroded lines, etc in future oil change visits. The undercarriage of my truck is a corroded disaster. The rocker panels are gone. Corroded railer hitch was replaced. Luckily nothing has totally failed yet to cause an accident.

Starting at <5K miles the vehicle power train clunked when shifting from 2nd to 3rd gear. Now at 70K miles it clunks when shifting between all gears except final drive. The dealership replaced the output shaft on the tranny, then the U-joints, and modified the electrical shift patern. It still clunks. Power steering intermittently locks up at slow speed turns, especially when braking. Light bulbs burn out almost every three months. Had to pay ($486) for replacing the intake manifold gasket when vehicle had little over 40K miles. Brakes fade and the pedal almost goes to the floor, again intermittent. I have almost caused several accidents due to the steering and brake issues. GMC issued a letter stating "this is a normal occurance and will not cause damage." Well, it's getting worse in sound and clunking harder during shifting.

2003 GMC half ton Sierra truck. 3 time since 2003 that I've had to take it in for clunking noise felt thru steering wheel. Lubed a couple times then replaced the intermediate steering shaft. Still no guarantees that it won't happen again. Also very hard to steer when braking and brakes don't respond well when applied quickly. The first time the intermediate steering shaft needed attention the truck only had 15,000 miles on it. The second time was 30,000 miles and the last time was 45,000 miles and occurred in March 2010.

Clunking noise and vibration in steering column at low speeds on bumpy roads, especially when turning corners. Feels like serious front-end mechanical problems. Current mileage on my 2003 GMC Sierra is 60,000. I learned from GM that the intermediate steering shaft had already been replaced at 24,000 miles under warranty, but it needed replacing again. $207 for new shaft and $92 labor. New, improved part # is 19153614. If GM knew the original shaft was defective, why didn't they have to recall it?
