I bought a 2003 Chevy Silverado 2500hd 15 years ago and gave it to my 16 year old son. Recently we noticed that the brakes and steering was acting funny and making a noise, so we replaced the power steering pump and hoses. The problem only started getting worse. I did some research and found an old recall or notice related to the hydro-boost relief valve that was defected because of O-ring failure. Just searching the vehicle will show several sites revealing the problem. The nada site goes into more detail on the problem. We have parked the truck until a decision is made. I contacted the manufacture and they stated that there was no problem, the vehicle has trouble when steering and looses braking.

I purchased my Chevy Silverado truck in 2003 new off the lot at [xxx] in roseville California. Within a couple years, I made a left hand turn at an intersection and lost power. I nearly hit a homeless man with a shopping cart, as I came up over a sidewalk. I called Chevy and got towed back in. They told me it was a solenoid? they fixed it and that was that. A year later, I am driving down a busy major street and make a left turn. As turning I lose power and my truck dies. Cars behind me honking. Light changes to red and cars still behind me. Now other lights are green. I turn my key again and it turns on and I get out of the way. I have 4 teenagers in my truck with me screaming. I take my truck to [xxx] and they test drive. Nothing happens. They say there is nothing to fix. Couldn't get it to die on them. A year later, make a U turn on busy street. It dies and loses power. I have no brakes and no steering. Cars honking. Again take it to [xxx]. nothing. A year later, taking a car load of women out to dinner and drinks. All hard working mothers. I am the only non drinker. At midnight I am taking the women home. U-turn at intersection, and truck dies. Again. No brakes or steering. Scared women. Turn it over and it goes. I take my truck to [xxx]. they have just moved to another building down the street. All my records of ignition problems gone. They have no idea where any of them went. They test drive. Nothing. They have yet to fix anything on it. It hasn't done it in over a year. But no telling when it does happen. It just happens. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Started the truck and put into reverse. There was no brake and no steering control. I had to use the emergency brake to stop the vehicle. All fluids were topped off as normal and I regularly maintain this vehicle. After reviewing this issue in the diesel forum numerous duramax owners have endured the same problem with some ending in crashes. This is a major safety issue!!!!!!!!!!!! simultaneous brake and steering failure. Are you kidding me? wow! I tried chatting with GM and was dumped during the chat. No help there! I'll try again!

We have a 2003 Chevy Silverado with 58,000 miles. There is a loud clunking sound coming from the steering shaft. When I asked about it I was told it could be greased but the noise would return. My son is an auto salesman and has talked to other people who have the same problem or have had the steering shaft replaced. Should not the dealer or GM in particular be responsible for this repair.

I have a 2003 chev. 2500 4X4 est. Cab long box. It has 18000 miles on it. I had to replace the rear brakes and rotors at 18000 miles. This is unacceptable for a truck of this type. (heavy duty). I also had a dim brake light on the dash, which I had checked out at the dealer. They said it was in the dash board and would cost 400.00+ to fix. The dealer also said the steering was loose and this was caused by the factory when installed, 250.00+ to fix. What kind of product are they making?

On 25500hd Silverado, steering has to much free play and is sloppy. Steering also wanders. Had alignment done 3 time within 2 month period, and steering shaft replacement per bulletin - did not correct situation. Still wonders to left. Not safe when hauling a trailer or not. To date this has not been corrected properly.
