Question about 2004 Chevrolet Monte Carlo

Speedometer Not Reliable

After starting engine, speedo needle is not always on 0 mph. Sometimes its on 20, 30, or even 40. It clims with increased speed but this causes the speedo to read 20, 30 or 40 mph faster than I am really traveling. The opposite is also true. Sometimes it starts below 0 mph, thus I travel faster than the speedo reads. And then again, today it may be fine. Any history with this problem?

    same problem....2004 monte carlo ss

  • Anonymous Jan 05, 2009

    Had the same exact problem on my 2004 Monte Carlo Supercharged SS at about 45,000 miles. NO WARRANTY. Contacted my Chevy dealer and they told me $850.00 to replace the whole gauge cluster. I contacted GM customer care ( you can find their phone number at GM.com) after explaining to them that this should not happen at 45,000 miles or even at 200,000 miles with the gauge cluster they told me they will contact the dealership. Basically with the help of GM directly i ended up paying $100 of the $850 and GM picked up the rest. THIS IS A HUGE PROBLEM with A LOT of GM vehicles.

    same problem, works more in the summer than winter, 2004 ls model

  • Anonymous Feb 18, 2009

    I had to replace my gauge cluster twice when I first bought my car, for the same reasons. I notice, too, that my odometer tracks mileage a bit faster than it should, adding two miles for every 100 I drive. How do I know? Because I've been doing some of the same long-distance drives for years... Good luck!

    I have the same problem. I bought a 2004 MonteCarlo SS Intimidator back in Aug. with just over 35k miles on it. It started messing up in Sept. Seems to be more affected in the cold. I've just kind of had to deal with it though. I can't afford to get it fixed right now

    gage stopped working about 1 year ago, it would stop on 10 20 30 etc, and it would go all the way to the right as far as it would go. We did contact our dealer who told us this seems to be a problem with the 2004 Monte Carlo but for some reason it hasn't been placed on recall list. And the dealership wanted close to three hundred dollars to fix.

Lol i have the same problem actually except mine is now stuck at 0. its a broken gear in the spedometer mechanism . it seems the only way to fix it is to replace the unit. if you can get one second hand, its not that hard to do...but it is pricy if you needto get a dealer to do it. (400-600)

Why is the speedometer reading erratically?


Depending on the type an year vehicle an the electronics on the car , the instrument cluster could be at fault ! The stepper motor that moves the speedo could be the problem if a GM product ! As far as the speed sensor goes a few other things wouldn't work very well if it were bad an the check engine light would be on more then likely because this is an input to the PCM - engine computer ! The transmission would shift erratically !
Speedometer
The IPC displays the vehicle speed based on the vehicle speed signal from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists.
So I would say the instrument cluster is bad !

Try disconnecting the battery again, only the + side. Wait for 3-5 min before hooking back up. Turn the switch on but not over, then start the car after a few seconds.

Boss has 2005 Yukon, says speedometer shows random numbers (ie, 40 mph while stopped or 40 mph when doing 60. Intermittent problem sometimes fine.) Any helpful hints appreciated.


The speedo in electronic and can have various circuit board problems. I've had to cars with erratic speedos and in both cases the dealer said replace them and big buck bills. I found a shop that repairs them and charges $100 buck and free shipping back. About a 4 day turnaround.

My speedometer needle is stuck at 140mi mark


when the car is parked and running what does the speedometer read? if "0" it is most likely the speedo transducer<mounted in tranny> if holding still it reads anything higher than "0" it is the speedo itself which requires dash cluster replacement. if that is the case will need to go back to dealer so new dash cluster can be coded to the car.

Speedometer is stuck all the way around to zero and won't move


sounds like you may have several problems here, there is usually a transducer on the gearbox, this may be faulty, there is always fuses for most electrical items such as lights, the window motor may have a faulty motor or it could be the switch, try swapping switchs from a good window
