1) speedometer gradually began to fail, registering false speeds. 2)in the dark, I was driving too fast for road conditions, my speedometer was stuck at a lower speed indicated. (I was not involved in an accident or issued violation) 3)the instrument cluster needs to be replaced. This is a common problem (I belong to Silverado enthusiast forum) further this is apparently a GM problem, as an 05 Chevrolet Impala I drive at work (police cruiser) has the same problem, which led to an erroneous issuance of a speeding violation on a pace (corrected at court). I feel this is a safety issue, especially when traveling at night without surrounding traffic as a reference.

: the contact stated the speedometer stopped working without warning. While the vehicle is parked, the speedometer reads 85-120 mph and is unreliable while driving. The dealership determined there is a short in the instrument panel cluster and it needs to be replaced.

9 January, 2006 to whom it may concern: I would like to report two safety related problems with my 2003 Chevrolet Silverado pickup truck. While driving through Illinois last year, I experienced the failure of the speedometer. I had been on the road for 12+ hours and was the only car on the interstate late at night when I began having trouble maintaining a consistent speed and was uncomfortable in general with the quality of my driving. Feeling that I must be too tired to continue, I pulled off the road at the next interchange. When I stopped I noted that the speedometer continued to read 60 mph. This vehicle had approximately 40,000 miles on it at the time. The other problem is more recent. The vehicles flashers come on when the left turn signal is applied. This is very confusing to other drivers around me. The manager of the company fleet reports that there are two company pickups of the same vintage that have also experienced unreliable speedometers early in there lives. The Chevrolet dealer states that he has not experienced these problems before. Please let me know if this is an ongoing problem with these trucks or an anomaly. Thank you, .

The speedometer on my 2003 Silverado started sticking, not resetting to zero. This allowed the vehicle to fail to show the correct speed. At times, I could turn the vehicle off, and restart several times in a row to make the speedometer reset back to zero, but now it will not reset at all. I have heard from several dealers that this is a common problem, if that is true, why hasn't General Motors done something to correct this problem, such as a "recall"?? this to me is a serious problem, and the manufacturer should be taking the proper steps for repairs! if I cant get this resolved, I can guarantee I wont purchase another GM vehicle!

Speedometer erratic, sticks at various speeds, does not display correct speed. Part is on national back order. Was told by chevorlet dealership that this problem exists in 2003 and 2004 Silverado trucks. Internet search for others experiencing this problem provided numerous results. With road conditions in fla subject to change without notice due to rain this is a very unsafe condition, its hard to drive safe if you have no idea how fast you are going. Was told the part will be at least 2 months back order.

Wire short in wires leading to the drivers door and rear door. Wires shorted out behind left kick panel and partially melted the kick panel. No modifications to truck - seems they were installed poorly from the factory. Dealer is charging to fix and replace wires and reprogram the door control module. Shorts caused air bag light to come on - dome lights failed to turn off - left rear window rolled itself down while truck was sitting unoccupied - all power windows failed - battery completely drained.

Speedometer does not work properly. Sometimes it does.sometimes it doesn't last I heard there was a national backorder on the cluster. To me its a hazard.

General Motors have a faulty neutral safety shift switch on their Silverado 1500 1/2 ton pickups that may lead to failure and cause the truck to burn. I have brought this to the attention of General Motors but they ignored me. My truck burned and we put it out. I see others that have burned and I bet the neutral safety switch is what started it. If you were to investigate how many 03 (maybe newer maybe older) have burned you will find the cause in this switch.

When braking at any speed brake pedal would go to the floor, and there would be extended stopping distance. Dealership was notified, but did not resolve the problem. ABS displayed brake system failure. The consumer stated that the brakes failed on inclines. The consumer stated that there was an electrical short. The odometer failed and added extra mileage. The tires started separating after 300 miles. The radio became hot and shorted out. The air conditioner shorted out. The consumer stated that the new vehicle checklist was not filled out nor reviewed with him. The consumer stated that the engine knocks. The consumers fingers were burned by the radio after it got hot. The consumer stated that he heard a growling noise in the power steering. The consumer heard a buzzing noise in the transmission. The consumer had to use the emergency brake to stop the vehicle coming down a hill. The right headlight went out and turned black. The headlight was replaced with the wrong high beam light. The cd player will not take the cd. The speedometer will only go to 20 mph at times.

2003 2500 silvarado with 36,000 miles. So far the transfer case shifting module (dropped itself inot 4 low at 70 mph), transmission (became so sloppy that it slammed passengers around had to be rebuilt), air conditioner compressor (quit working and the new one works poorly), fuel pump (died in the middle of Utah and took 4 days to get the part), radio (had multiple problems had to be replaced after 4 visits), keyless remote failures, and 4 recalls.

While driving at any speed dashboard lights warn the consumer of impending danger. A light would inform of reduce power and go out. Then, another light would warn of reduce brake power. Vehicle will not stall, but only have limited power. Dealer placed the vehicle on a diagnostic machine, and found a computer glitch. This problem occurred three times in two months.

- Horseshoe Bay, TX, USA

Vehicle caught fire while parked in the driveway. (nar) fire was due to a mechanical and/or electrical problem with the vehcle. The fire not only destroyed consumer's vehicle but damaged the siding of the house.

Vehicle seems to go into 4-wheel drive by itself while driving. This has happened to me three times already. I want to switch dealers but GM told me no I have to stay with the dealer who worked on the vehicle. As this happens the vehicle slows down considerably causing the seat belt to lock and hold me back. Also at times the vehicle just slows down while at highway speeds. The check 4 wheel drive light comes on and the push buttons on the panel do not operate. (the lights go out) I also think this has caused my odometer to fast forward. It tells me now that I have 29900 miles on the truck. I have all records and need help. I travel to work 8 times a month and round trip is 114 miles this does not seem to work out. Can they check the electronics and see actual miles from the computer.

- Beachwood, NJ, USA

4X4 does not activate when needed. Taken to dealer 4 times for the same problem. Bullatin out from dealer to service techs stating there is a computer problem in the 4X4 program and at this time chevroet does not have a remedy to fix the problem.

My 2003 Chevrolet Silverado caught on fire and burnt after being parked for at least and hour and a half. It was a total loss.

- Dora, AL, USA

At 4,702 miles the "check engine" message displayed. Onstar confirmed truck required service within seven days. Boardwalk Chevrolet in redwood city diagnost the problem as "PCM not reading throttle angle" and the problem was correct.

- San Carlos, CA, USA

Lights for instrument panel occasionally does not work. Battery died. Radio made loud humming noise even when car shut off overnight. Air conditioner broke. But the continual problem is the 4WD becomes inoperable and service 4WD message appears. GM has no repair. They state I must stop turn off the vehicle and restart it in order to "wake up" the electronics. It has been in the repair shop 4 times in last six months when I bought it new. The dangerous part is while driving in ice and snow the vehicle's 4WD became inoperable resulting in loss of control of vehicle and a near miss crash.

- Emmaus, PA, USA

Erg valve failed 4-6 times. Standard alarm on truck turns on and off by its self. Doors lock and unlock by themselves. Loses power to the vehicle while driving. When you open the glove box the cargo light comes on.
