Instrument cluster panel of all gauges including speedometer and gear selection ' gauges can quit working with no warning , leaving the driver unaware of speed or distance traveled. also not knowing what position the gear selector is in . ( park, neutral , drive etc. ) could allow the vehicle to drift away on it own with no one behind the wheel when not being driven . can happen at any moment , any place !

Traveling on highway when smoke started coming from the dashboard. pulled over and within several minutes the whole truck was on fire.

Tl* the contact owns a 2003 chevrolet silverado 2500. the contact stated that the blower motor malfunctioned and would not operate using the first three settings. the blower would only operate in the number four and five settings due to an electrical shortage. the vehicle was not diagnosed nor repaired. the manufacturer was not notified of the failure. the failure mileage was 65,500.

Instrument cluster just quit working altogether. this will be the third time the cluster will have been replaced. the first two were on gm; this one is going to be on me. what in the world is wrong with gm or the manufacturer of this part. why do they keep producing crap? until the cluster is replaced, i have no idea of engine functions and if it weren't for my gps, i'd have no idea of my speed. *tr

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... *tr

Started the truck and put into reverse. there was no brake and no steering control. i had to use the emergency brake to stop the vehicle. all fluids were topped off as normal and i regularly maintain this vehicle. after reviewing this issue in the diesel forum numerous duramax owners have endured the same problem with some ending in crashes. this is a major safety issue!!!!!!!!!!!! simultaneous brake and steering failure. are you kidding me? wow! i tried chatting with gm and was dumped during the chat. no help there! i'll try again! *tr

Tl* the contact owns a 2003 chevrolet silverado 2500. while driving 40 mph, the reduced engine power light illuminated on the instrument panel. the vehicle stalled in the middle of the highway, but the contact was able to pull over to the side of the road. the vehicle was taken to an independent mechanic where it was diagnosed, but not repaired. the manufacturer was notified of the failure. the failure mileage was 195,000.

Speedometer randomly increases, decrease or will not work at all. oil gauge fluctuates also the heater resistors burned up. *tr

Engine does not idle and shuts off. according to internet sites, its a wire failure in the throttle body connector. can be a major issue when you come to a stop. some times will not restart right away. *tr

Tl*the contact owns a 2003 chevrolet silverado 2500. the contact stated that the transfer case was designed with a defect. as a result, the pump in the transfer case wore a hole from the inside to the outside of the transfer case. this allowed the oil in the transfer case to pump out the hole and caused the transfer case to run drive. the dealer stated that the vehicle was out of warranty and the contact would have to pay for the repair. the failure mileage was 130,000. updated 3/16/09 *cn the power steering started leaking fluid. the dealer informed the consumer the power steering fluid leak was coming from the hydro booster onto the power steering gear. the consumer lost his brakes. it was discovered the booster rod was missing. the parking brake did not work and the instrument cluster failed as well. the speedometer did not work it was reading 60 mph even when the vehicle was parked. updated 03/18/09. *jb

Speedometer is malfunctioning. *tr

I have had speedo problems for over a 1 year. now it has become regular. this is a safety issue. chevy told me to go away because i am over mileage requirements. i see i am not alone. there are thousands of wacky speedometers out there. this kind of service has convinced me that chevy doesn't deserve to be in business anymore. the jokes will no longer be about fix or repair daily (ford). *tr

My speedo went out on my 2003 shevy 2500hd at 116000 miles.i went to start it on a cold day and it was reading 20mph in park.today it reads 70 mph in park and is reading over 70 mph over the speed that i am driving.*cn

All gauges stopped working on my 2007 chevy silverado. *tr

Speedometer in my 2003 chevrolet silverado 2500 hd is erratic. sometime it works fine, other times it will register 30 mph at a stop. other times it shows 120 mph when driving 65 mph. some times it doesn't work at all. *jb

The speedometer in my 2003 silverado hd crewcab 4x4 has broke. the indicator (needle) is now on the extreme right of the gauge. after doing some research i have found that this issue is common and the stepper motor will need to be replaced. to do this the entire instrument cluster may have to be replaced. *nm

I have a 2003 chev. 2500 4x4 est. cab long box. it has 18000 miles on it. i had to replace the rear brakes and rotors at 18000 miles. this is unacceptable for a truck of this type. (heavy duty). i also had a dim brake light on the dash, which i had checked out at the dealer. they said it was in the dash board and would cost 400.00+ to fix. the dealer also said the steering was loose and this was caused by the factory when installed, 250.00+ to fix. what kind of product are they making? *nm

1. city and highway driving. 2. speedo sticks almost always now. 3. gm wants $700 to fix the problem, but others on web say it is temporary fix. *nm

Dt: 2003 chevrolet 2500 hd truck experienced an engine power reduction. the vehicle operated at a reduced speed. it goes at a crawl. this occurred at speeds of 40-50 mph in the middle of traffic. has to coast over to the side of the road, on average about 10-15 seconds after cutting off then the engine restarted. this usually happened after vehicle has not run for an extended period of time such as being parked overnight. took to a dealer, who replaced the accelerator pedal that ran by wire not cable. this was electric and computerized and some sort of signal went through the accelerator pedal and caused this failure. the vehicle will idle, but lost power. this has been a problem for the last 3 months. the problem recurred even after the replacement of 2 accelerator pedals. *ak

Dt: 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. *ak

Intermittently dash board lights and gauges will go blank. when the dash board lights go blank consumer cannot determine how fast the vehicle is going. the dealer examined the vehicle five times.*ak
