Been having problems slowly with the battery running out because something is still running in the vehicle but everything is off. The gas gauge gear control lighting on the panel door on the passenger side will not lock speedometer is not working gas gauge is not working was checked by a mechanic and he address that something is not constant running even though everything is turned off that cause the battery to run down when it is off. Also the lights don't light on the right side stays on and never goes off when running the vehicle. I noticed this on a lot of 2500 Chevy trucks. We have taken this vehicle in to be check. Please help us to resolve this problem as soon as possible. Thank you for your time. Looking forward to hearing back from you sun.

I was traveling on the interstate with my family aboard at the speed around 75+ mph and suddenly the vehicle looses speed while traveling among others at around the same speed or higher when suddenly the speed decreases to no speed, and a this warning comes across the dash panel, that says reduced speed and all these 18 wheelers are behind me and around me. The more I press the accelerator it would do nothing but almost cost my wife a heart attack from the big trucks blowing there horn and fearing the day lights out of my family. Then a week later the cluster starts acting all crazy with the lights going out and on, and now they aren't working at all. The gauges stopped working the speed along with gas gauges etc... while I have never owned anything other than "Chevy's", trucks and cars I have seriously been considering another name & make in my next choice of purchase.... so a loyal friend advised me to send GM a E-mail explaining my issues...

The contact owns a 2003 Chevrolet Silverado. The contact stated that the vehicle suddenly accelerated without warning while in reverse. The contact crashed into a pile of debris.

2003 Chevy Silverado speedometer moving erratically. Gets stuck at 120mph.

- Uniontown, OH, USA

Reduced engine power message and drops into "limp mode", there is no problem with engine overheating. The computer give a code 1516 "drive by wire" sensor calibration problem. Dealer indicated "yellow" wire broken on some vehicles others have to replace the throttle sensor. Danger is on loose of power in traffic, instead of a message to check the engine.

: the contact stated while driving 45 mph, the speedometer would not move. Even while driving at higher speeds, the speedometer displayed 0 miles per hour. The service dealer was not contacted however the manufacturer provided the phone number to file the complaint.

I have owned my 2003 Silverado for just over 3 years. I have had several problems already: 1) the air conditioner would only blow out hot air-- has been fixed. 2)vibration noise in rear end around 30-40 mph--?? can't be fixed/duplicated. 3) speedometer quit working--replaced at my cost; warranty just expired, go figure; also had to go to court to fight speeding ticket! ( relative has same truck, same problem!) 4) windshield wipers will not shut off, I get to pay for this one too, after warranty. I had to pull the fuse out! not very safe in crazy mi weather!! 5) also had tailgate cables replaced under recall. 6) back seat loop replaced due to recall. No wonder Chevy is not doing well, who wants to spend over $30,000 for a piece of junk! will not buy another.

: the contact stated the speedometer failed while driving on the interstate. The vehicle cruise control was set for 70 mph when the speedometer needle began reading 120 mph. The contact did not notice a change in the actually speed the vehicle was traveling. The cruise control was reset at 70 mph and the speedometer continued to register at 120 mph. The speedometer never worked properly again. The dealership replaced the speedometer cluster.

Purchase truck used in June of 2005 with 49000miles truck has less then 55000miles on it.. first day ran out of gas..gas guage and digital reading showed 50 more miles worht of gas.fixed thegas guage problem or so they say then oil guage started showingway past full on oil then would go back to no oil then to normal speedometer sticks and on occasion will go back to zero for the most part your start off speed is at least 40mph.. was told by dealer it was a faulty I.C.P and that they have been having several brought into the dealership with the same problem.. I feel if this is a problem that obviously Chevy is aware of it should be recalled and fixed with no out of pocket expense to its consumers. Was also told that my dash would have to be shipped out of town to be repaired and that I would be without a vehicle for awhile.. I am truly disappointed with what I thought would be the perfect truck considering its a 44000 dollar vehicle only to find out I need to spend an additional 4-500 dollars.. wow what a disappointment:(

The consumer complained about several problems. While driving he had trouble shifting from first gear. The dealer reprogrammed the engine control module and the transmission module control. The vehicle was still shifting hard, and the rpms revved. The replacement of the aforementioned did not remedy the transmission problem. The second problem was with the brake light coming on the cluster assembly. The service dealer replaced it, and it seemed to work well at this time. The third problem was with a noise in the rear of the vehicle. The dealer replaced the gear kit, two gaskets, case, the rear differential carrier assembly, carrier gears, and shims. The noise was still heard. The dealer recommended that the contact install carpet to cut down on the noise. The final problem was with a loss of rear traction. The dealer has been unsuccessful in identifying the root of the traction problem. The cruise control stopped working. Updatd 11/29/05.

We have a 2003 Chevrolet Silverado and a 2004 Impala. Speedometers have broken on both. The Impala was replaced under warranty. The Silverado was turned in under warranty but not repaired and now it is out of warranty. This apparently is a major and widespread problem with Chevrolet vehicles and the company will not stand behind the product. Bob howard Chevrolet in Oklahoma city tells me cost to fix this problem is $400-600 for the part and $125-175 for labor. How many of these module clusters have prematurely malfunctioned? mechanics and GM service centers say they are on national back order. That should illustrate the need for review and recall.

The consumer states that 2003 Chevrolet C 2500 was having a message on the instrument panel showing reduced engine power. Then, the engine immediately dropped power. The speed will dramatically slow to around 15 mph. This happened 5 times currently. There have been several near misses as a result of the power reduction. The vehicle has been in the dealership 5 times for the engine power failure. The dealer replaced three times the wiring harness to the throttle position sensor, throttle body, power train control module, throttle actuator, control module, also, the ignition switch was replaced and the engine was still losing power. The manufacturer has been contacted, and the customer service department was very unwilling to help or provide the address to the regional office. The customer service representative was very rude and refused to transfer the call to his supervisor upon request of the consumer.

My speedometer and tachometer quit working along with a tail light my mechanic said the part alone would cost $300. I thought my tach was still working until I got a $150 ticket. I can't afford that much especially with my ticket.
