This just started right out of the blue. My speedometer works very erratically. Sometimes it reads 30mph when im doing 70mph and sometimes it says 30mph when im not even moving. It can also be any combination of any speed. It just does whatever. Sometimes it works fine. Usually when it starts to go bad it eventually will just drop to below 0mph and stay there. Now the tachometer is doing the same thing. Both occur totally at random. This could easily lead me to have an accident if I don't know how fast im going. Nothing has been done to fix it because I really don't think I could afford to get it fixed and I know nothing about automobile electronics either. The car is a 2004 Chevy Monte Carlo ss with 61,000 miles.

The contact owns a 2004 Chevrolet Monte Carlo. The contact stated that the instrument clusters on his vehicle failed without warning. All of the gauge needles on the instrument panel were pointed downward and inoperable. While driving, the contact was unsure of his speed including how fast or slow he was driving. The manufacturer advised him to have an authorized dealer diagnose the failure. The manufacturer also mailed the contact a letter informing him that the warranty is not valid for the repair and that there are no related recalls. The contact is responsible for paying $450 to have the vehicle repaired. The contact filed claim# 71-762-310145 with the manufacturer. The failure mileage was 64,776.

The speedometer on my 2005 Monte Carlo fluctuates and will stick at past 140 mph when I am driving along at posted speeds. Also, my gas gauge will surpass the full mark when I know I have less than full.

Bad stepper motors in my tachometer, voltmeter and now my engine temperature meter have died or are faulty, producing erroneous readings. The failures seem to be randomly occurring as the motors slowly die out, giving false readings in each gauge until they are permanently stuck in a position. This has occurred to each meter over the last several months, with meters giving incorrect values, sometimes resetting and functioning properly once the engine is turned off and back on, but then becoming incorrect once again. Consequences of this could lead to further damage to the car in case an actual problem occurs in areas of the car where monitoring the situation would eb critical, such as in my case when my engine coolant was running very low but I could not tell due to the gauge being broken. Serious damage to my car and potentially myself could have occurred. The only available option is to purchase a new dash cluster for several hundred dollars, while the problematic motors cost $5 each to replace but altering the dash is not legal.

Instrument cluster/ speedometer malfunction, erratically reads vehicle speed or not at all. All else works well. Love my monte but it is annoying to say the least to be as O.C.D about my car as I am and to have this major part of communication between car and driver go bad Chevy admits to having an issue with this item, but will do nothing about, unless I fork over $ $600 for parts and repair. Chevy.... god don't like ugly!

Approximately one year ago, I started noticing that my tachometer on my 2004 Monte Carlo ss was not functioning properly all the time. It is an intermittent problem, and I have since learned to live with it. Well now the speedometer started yesterday with a very similar problem. It will only register the highest speed I get to...and stay in that position until the car is almost at a dead stop. If you reduce your speed, you can not tell how fast you are going. I have done a lot of research on line regarding this, and it is apparent that Chevy and GM trucks from 03- and 04 are covered by a safety recall for this identical problem. I contacted the local dealership and they stated it was not a known issue with the Monte carlos...however internet search can produce cars of all types in that date range that all have had the same failure. This is a 2004 Monte Carlo ss that just has 36600 miles. And the problem has been apparent since last summer (just a month after it went out of the "date" warranty)...

I purchase a 2004 Monte Carlo ls in Oct. Of 2007. The instrument cluster worked ok until 3 months after I had the car. Now the tach is never where its supposed to be. Sometimes it will jump past the red zone on its own. I have some other friends that have a 2004 Impala that is showing the same issues, with the tach and speedometer. This seems like a major safety issue and needs to be addressed. I have read many forums online describing this same issue.

Instrument panel malfunctions. Tach, gas gauge, and speedometer. Only work intermittently. Sometimes I look at speedometer and it says 70 mph when I am doing 25 mph and sometimes it says 25mph when I am doing 70 mph. Started at about 50K miles. Chevy did recall on trucks of this year for the same issue but did not include Monte Carlo's. replacement cost can run anywhere from 600 to 2000 dollars. Money I do not have at present. Filing complaint to add to other complaints. If enough complain then maybe Chevy will do something.. one of those things you expect never to go wrong.........

Speedometer stopped working vechical only had 19,000miles.

- Loveland, OH, USA

I have a 2004 Monte Carlo ss, at about 55,000 miles the speedometer starting acting unreliable. Sometimes I registers 30 mph when I am at 70, other times it will stick at 71 mph when I am at zero. It occurs randomly with different behaviors, is unreliable. I called the local GM dealer and they mention it is a problem with the instrument cluster. This is a safety issue and other GM vehicles I am told had recalls for this same issue. Not being able to reliably know the speed in all situations is a risk to the operators.
