My speedometer recently malfunctioned at around 77,000 miles and I brought it to the attention of the dealership's service manager, jeff bevington, at rally GMC auto group in palmdale, CA (where I purchased the vehicle new in 2005). I was given service bulletin #07187c - special coverage adjustment instrument panel cluster gauge needle function (March 20, 2009), which indicates the following: this bulletin is being revised to include certain 2005 model year vehicles in the u. S. Additionally, for u. S. 2003-2005 model year vehicles, gm will provide the instrument panel cluster (ipc) only, at no charge to the customer for verified failures between 70,001 miles (110,001 km) and 80,000 miles (130,000 km). Any additional costs, including labor to replace the instrument panel cluster, will be the responsibility of the customer. Dealers will be responsible for the return of the customer's ipc back to the electronic service center. Please discard all copies of bulletin 01787b, issued September 2008. The VIN breakouts of vehicles involved in the bulletin include 2005 GMC Sierra between 51100001 and 51347001. However, jeff bevington told me that since my vehicle is older than 7 years and over 70,000 miles, it is not covered??? he suggested I call the gm toll free number (800) 222-1020 and ask if they can help. I called and spoke to dontes who told me that gm has no record of the service bulletin mentioned above???.

This is the point at which I discovered that I have bad tires. The tires have be come badly chipped and pieces of rubber tread began coming from tread area. The sidewalls discolored and began cracking. The tires started to loose air and had to be reinflatted all the time to present. Tire has same symtoms as re-called tires but michelin and gm would do nothing to help.

After applying brake to slow down to < 5 mph (not coming to a halt) and then trying to accelerate, vehicle becomes unresponsive for 1 to 2 seconds; it feels like the transmission goes into neutral during the braking period and when gas pedal is applied, there is a 1 - 2 second time period where vehicle is trying to figure out something and prevents any acceleration. Why is this dangerous? I found myself in a left turn only lane/green light with opposing traffic, and I attempted the left turn with oncoming traffic because I thought that I had ample time but the vehicle just sat there for 1 - 2 seconds, and with that I found myself in a dangerous predicament because the oncoming traffic was getting very close. If the vehicle had responded when I needed it to, it would not have been a close call. This behavior with the vehicle can be reproduced at will, every time. There are many forums on the internet where many people are complaining about this same issue with the drive-train, GMC knows about it, but refuses to do anything about it.

At any rate of speed truck will go into reduced engine power must pull over out of traffic and kill engine wait a couple of minutes and then restart sometimes you can go 1 mile till happens again sometimes 50 miles very dangerous situation in heavy traffic.

Erratic speedometer - after 20-30min. Driving, needle will suddenly drop to 10mph and your still at 55 or higher. Will eventually go to 0. Once vehicled cools down, speedometer seems to work again, temporarily.

After sitting in stop-and-go traffic I noticed that the speedometer was reading at 100 mph and I was at a stop light. At the time, I had less than 50,000 miles on my truck. Since then the speedometer was almost always incorrect. It has occasionally fixed" itself, but usually did not last more than a day or two. The needle was often buried past 120 mph. A number of my friends and relatives with similar vehicles had the same problem. Currently I have not paid to have the problem fixed, but hope that it will be recalled at some point soon.

My speedometer went from working normally to now it sticks at various speeds at a stand still 70 to 80 mph or not working at all or over 100 mph when driving probably 30 mph am not sure how fast I am going. After researching to see if any others were having the same problem I found that many gm customers are experiencing the same problem with their speedometer. Some of them actually paying thousands of dollars while others are paying 4-7 hundred and still having the same problem hours later after paying to have it fixed. I called a nearby GMC dealer and asked if there was a recall for the speedometers they said that there was not but that they were getting a lot of calls for the same problem and that there was a lot of concern. I would like to request a recall of the speedometer equipment on 2004 gm trucks .

The contact complained about many defects with this vehicle. The speedometer continually had an inaccurate read out while driving. The dealership believed this failure could be related to the wiring harness. Since they were unable to duplicate the problem no repairs were done. Also, the vehicle stalled at various speeds without warning. While the stalling occurred the contact pressed hard on the brakes to elevate the stalling. He believed this was due to the power brakes. The vehicle stalled on occasion and would not immediately restart. The dealership made numerous attempts to correct this problem w and all attempts have been unsuccessful. This included replacing the fuel pump and electrical control module.

Driving my 2003 GMC Sierra and the speedometer went out , it was going 100 miles per hour when I was going around 50 - 55 ? hard to tell it never right any more and I only have 58,000 on the odometer . This a safety problem and GMC should recall these clusters before people start getting hert because the speed is way of , and the dealers want use to pay around 1200. 00 to fix. This is a GMC fix not.

Since we've had this truck, the acelerator sticks and you have to press it hard to get the vehicle to move, then it races for a second and jumps forward or reverse. This happens when it is at a complete stop, when you're starting off. It is dangerous in traffic situations, such as frequent stop & go traffic, and when you're trying to maneuver in tight spaces, such as parking. I'm sure that it also causes excess fuel consumption.

While applying the accelerator pedal vehicle failed to move. After applying the accelerator pedal numerous times the vehicle jumped and surged forward. Consumer was able to maintain control of the vehicle, and drove it to the dealer for inspection.

The vehicle would jerk forward 6 inches when started. This would occur when the vehicle was in the park position. The dealer told the consumer that nothing could be done. The problem also could not be duplicated.

While driving, coming to a complete sudden stop, and upon depressing the brakes pedal, they went completely to the floor, and the vehicle would not stop. The consumer then placed both feet on the brakes trying to stop the vehicle, the vehicle accelerated, resulting in an accident. The consumer rear ended another vehicle. The consumer requested to be reimbursed for the expenses.

When using feature "fly by wire throttle" the accelerator cannot be controlled. When encountering anything more than the slightest bump or variation in the road or on the highway, it was impossible to keep constant pressure on the accelerator. When the vehicle went over a bump etc. Action was unable to be controlled and the accelerator was severely depressed which caused an increase in speed and then a voluntary release of the accelerator, even when the consumer knew he was approaching a bump, he was unable to control the accelerator.

I am having trouble with my throttle when attempting to accelerate from idle. It feels as though something is sticking, then suddenly releasing once enough pressure is applied to the accelerator pedal. This results in the vehicle lunging forward every time.
