Problems with 2004 Chevrolet Silverado 2500HD ELECTRICAL SYSTEM

Speedometer is behaving erratically. sometimes it will read within 5 or 10 mph of actual speed (sometimes high and sometimes low) and other times it will read 0 or 100+. this has caused me to unknowingly travel beyond the posted speed limits at times and is creating an unsafe driving environment. i have contacted chevrolet and they are not willing to address this issue. *jb

Speedometer malfuntioned on my 2004 chevrolet silverado 2500hd. i noticed the malfuntion on the interstate while traveling at same speed as other drivers. my speedometer was reading 50 miles per hour and the posted speed limit was 70 miles per hour. i know that the average speed on that route is between 70 and 75 miles per hour. if someone were to drive through a school zone with the speedometer reading 20 miles per hour and were to injure a child while the actual speed traveled was in the 40-45 mile per hour range it would be gm's fault. it is well known to chevy owners that there is a defect in this particular insrument cluster and well known to gm. something should have already been done, but as of today no recalls have taken effect. *nm

Speedometer and tachometer became erratic, then failed completely. after researching, i found that this problem is common in chevrolet / gmc trucks. it appears that this is a defective part and that chevrolet / gmc is aware of it. my local dealer wants $500.00, a cost that chevrolet should pay. *tr

The speedometer on my 2004 chevrolet silverado 2500hd is not working properly. with the vehicle turned off it is reading 50mph right now. i also do not get accurate speed readings while driving, which could lead to me driving to fast/slow and possibly causing injury to myself or others.

Instrument panel failure in 2004 chevy silverado 2500hd the panel is required by law isn't ? chevy is very unco-operative with this if you have over 70,000 miles but as far as my experience goes you can and will get a ticket for an inop speedo. mine will hang up past 120mph and even when not running the rpm will read 4500. this is absolutely a safety issue and chevy should eat the replacement cost of $450.00. *tr

The tachometer registers incorrectly. the rpm indicator will only advance. with the engine off, it registers 5,000 rpms. also, the speedometer operates erratically. at times it indicates a lower speed than actual or no speed at all. none of these may be a safety hazard, but it makes compliance with posted speed limits difficult. *jb

Speedometer readings are inaccurate. gm issued special warranty coverage for vehicles with less than 70,000 miles. my issue was reported to the dealer at 58,000 miles, but was not documented in their system. speedometer readings are erratic. sometimes accurate, sometimes 50% or more less than actual speed. inaccuracy has increased over the last year. *tr

Digital instrument panel failure ( speedometer, fuel gauge, rpm gauge & oil pressure gauge all malfunction at 50,000, now at 81,900 miles. we received a recall letter a bit late. the recall was up to 70,000 or 7 years. called gm when recall letter was received dec.17, 2007. told us it was too late to fix because of our mileage. if only we would have received the letter way earlier. now gm can not fix the problem for us, unless we pay out of our own pocket! and they knew that the problem existed! *tr
