I was driving on an icy road outside of Chicago when I almost lost control of my vehicle due to speed creep this was caused by the speedometer of the vehicle failing and sticking at 37 mph. I estimate that when I skidded out that I was most likely going over 50 mph. I've had multiple problems where the speedometer has stuck afterward, but was able to avoid similar incidences because I realized their could be a problem. I am driving a 2004 Chevrolet Suburban. This is not a safe situation. If there were other traffic, structures, or pedestrians around property may have been damaged and people may have been injured or killed. It is not an isolated incident either. If you go to www.topix.net you can read 380 postings of people having the same problems. Just type in Suburban speedometer stuck.

My speedometer went from 55 to 120 in a matter of seconds. Then if you give it a couple of days it would be right again. Then all of a sudden I am driving down the interstate and it would go to 120 again. The dealership hooked it up to the computer and they said they "rebooted the cluster" and it's working for now. They said a lot of people have had this happen and it may only be a temporary fix. So what if I have my cruise control set at 65 and then my speedometer goes to 120? I see an instant accident happening! Chevrolet should have a recall on this issue.

I own a 2004 Chevrolet Suburban Z71. During the past week, the speedometer has been registering erratic speeds while driving at a constant pace. Today, the speedometer quit working altogether. The vehicle has only 59,450 miles on it, and has not been used in any off road Excursion. Not having an accurate speed reading while driving a vehicle of this size is a significant safety issue to the driver and passengers of this vehicle, and other vehicles on the roadway. I understand this is a fairly common issue with this make, model, and year vehicle. As such, I believe the manufacturer needs to enter into a safety recall to fix this issue.

Our speedometer quit working and would either sho us going much slower or much faster than we really were. We were hoping that it was just a sensor, but it was the wiring in the dash, they required that we send in the whole front module and they sent us a new one with our old odometer miles already set. They also required that we send in the old one. Our mechanic told us that they had just had to replace a pickups speedometer as well. Same year, and similar model.

At 35000 miles the speedometer would make a ticking noise and start moving with a notchy motion. When driving it could read 40-75 mph while doing less than 10 mph. At 60+ mph it could read 100+ mph. After multiple restarts the speedometer would return to 0. the problem seemed like it would worsen when the temperature was colder, but it could be coinsidence. Took the vehicle into the Chevrolet dealer where it was diagnosed as having a faulty guage cluster and replaced under warranty. While in the dealer there were 2 other people with similar trucks having the same thing replaced. Now I see online that this is common with nearly every Suburban and Chevrolet/GMC truck in model years 2004-2005. This should be a recalled part and could be a make for a costly/dangerous drive for someone.

Speedometer is erratic and inaccurate. Very dangerous!

- Rapid City, SD, USA

Speedometer and oil pressure starting displaying erratic reading any where from 0-120+ and oil psi of 0 to pegging gage. After research of dealers and repair facilities data confirmed this is a know defect and caused by defective stepper motors. Setting cruise control hamper this defect by not knowing what actual speed is when engaging cruise control. Also have second vehicle that just started with same issues today 12-22-06. 2004 GMC Yukon

Started having problems with the speedometer reading incorrect speed at about 40K miles. Currently have 55K miles on my 2004 Suburban. The speedometer often reads over 100 mph sitting in my driveway. It seems to occur after 30+ minutes of continued driving. Additionally, the tachometer becomes erratic and sometimes just drops to 0 while driving.

2004 Chevy Suburban speedometer goes crazy, sometimes set at 120 mph while setting still. While driving I never know the speed I'm going. One day my wife was driving the speedometer just kept climbing to 120 mph, that is when it started. Sometimes the speedometer goes down to 0 mph then while driving say 30 mph I guess it may take you to 60 mph, 80 mph while at the same RPM. Nothing has been done, it has 44000 miles therefore my warranty is out I have to see if the ext warranty I got covers this, also I have been checking the internet if anyone had similar problems and I have found numerous people on topix.net. Thank you for you're time.
