Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Started vehicle in morning and noticed no readings from any gages, (oil press., temp., tach., fuel, speed) nor could I read odometer. Surrounding dash lights functional. While driving, I hit a bump in the road.... everything began to work. At end of day leaving work, no problem..... stopped on way home, restarted, problem returned. Turned steering wheel, problem gone. Arrived home, turned vehicle off..... restart, problem back again. Search on net says it is the instrument cluster. What is the cost for new/used cluster" is it easy to install"

My 2003 GMC Sierra 1500 speedometer doesn't work. It shows high speeds after the truck is shut off. It seems to work in warm weather but doesn't work in cold weather. Not sure when the speedometer is accurate.

2003 GMC Sierra truck, steering, has a clunking noise started about 5,000 miles, told by mechanic to take to a dealer, was not the first time he had heard of this problem and was not something he wanted to undertake due to liability, another problem with to much play or (slap) in the drive shaft, took it to dealer they replaced drive shaft, did not solve problem, so apparently they did not know how to solve problem and basically were grabbing at straws, I still have problem, front running lights keep burning out (electrical problem).

Vehicle repeatedly goes into "reduced engine power" without warning. Very dangerous when you are on the highway and suddenly lose power. Has been happening infrequently for the last two years. Now happens almost daily.

My 2003 GMC 1500 extended cab pickup's instrument cluster is not working. Speedometer doesn't even work. This is not safe. I have to park my truck, or even get it taken for speeding. Not to mention if there is an accident because GM has a faulty part. That is not fair. I and thousands of others have complained to them but no solution. Plus I have less than 70,000 miles on my truck.

While going down the road my speedometer was showing 120mph and I was only running 75mph. When I stop and shut off my vehical the speedometer reads 45mph instead of 0mph. If you switch the ignistion off and on several times it will eventually go back to 0mph. I was doing some research on it and found this web site I found out pretty quick this is nothing new. There were so many listings on there for the same problem that it was unrealistic. I have always owned Chrysler products unitll I purchased my GMC. I have done nothing but bragg about howw I don't never have problems with this truck but now seeing all of these complaints for the same thing I kinda feel like an idiot. This is a very big safety issue exspecially when traveling the interstates. This could cause some prety serious wrecks when your showing your running 100mph and only doing 60mph. Thats asking for a major rear end collision. If any one is listening and is conserned about the consumers safety then something needs to be done pretty quick. I have read where consumers have spent thousands of dollars to make this repair. With as many complaints I have read there should be something done pretty quick before someone gets injured or even killed. So if any one cares do something about it.
