 I have a 2003 chevy silverado. i've started having trouble with the electronic dash. about two months ago it sometimes came on then off, but now it just stays off. nothing shows up. i have no clue how much gas i have, how fast i am going, how many miles on the truck etc... now i am told that it happens a lot with chevy's. the only way to get it fixed is to bring it in and taken apart then has to get sent out so then can computerize it to that truck. there is no other way, and that will take between a week or two. crazy!!!! now i have to rent a car in the mean time. chevy needs to pay for this.

 Bought 2003 silverado 3500 4x4 used in 2006. it had 125,000 miles and ran great. in october 2006, the speedometer started reading inaccurately the oil and battery charge gauge are not accurate either. i consider this a safety issue. i received a letter stating, the instrument panel may be defective. the problem i have is the mileage. it is over the maximum allowed to replace the cluster. i have over 200,000 miles on my truck. the truck runs great and i would not think twice about taking long trips(over 2,000 miles) as i do because of my work. i don't think there should be a mileage limit at all. there is clearly a major problem with the cluster. i think there needs to be a recall period, not just a letter stating there is just a problem. please look into this again. thanks d.h *tr

 I have a 2003 chevrolet silverado with 85,000 miles. the oil pressure gauge on the instrument panel stopped working at 80,000 miles. without the engine running the needle moves all the way to the maximum. i have herd from many silverado owners that they have experienced the same problem with there vehicles. why is there no recall with so many complaints? *tr

 The daytime running lights have failed due to what appears to be the overheating of the lamp sockets. when you go to replace the lamp' the sockets appears to be burnt and brittle and are missing the little metal tabs used to make contact with the lamp base. you cant replace the lamp. therefore i only have 1 daytime running light and am worried about a possible fire hazard with the other one. the one that works looks like it's not far from failing and very soon wont be working either. the more i see the amount of gm vehicles (trucks, silverado, tahoe, trailblazer, sierra, yukon & envoy's) without two daytime running lights, i really do wonder if gm has a real problem. i see several each and every day without one or both. i have spoke to other owners and they have the same problem with one or both of them. thank you for your time. *tr

 Tl*the contact owns a 2003 chevrolet silverado. while driving approximately 60 mph, the contact decelerated and the speedometer displayed inaccurate readings. there were no warnings prior to the failure. the vehicle was taken to an authorized dealer. the failure was identical to the one mentioned in the recall; however, the vehicle was excluded from the recall due to its excessive mileage. the vehicle has not yet been repaired. the failure mileage was 60,000 and current mileage was 88,500.

 On january 5, 2008 i arrived home at 11:30 pm and parked my truck in the garage attached to my house. i went to bed and at around 2:00 am i smelt smoke. i walked through the house checking rooms, when i got to the screen door to the garage the handle was hot. i then went out my front door and called 911. the truck was a loss and part of my garage. in less then 11 months this is the 2nd chevrolet/silverado that i have owned that has burnt. *tr

 I am the owner of a 2003 chevrolet silverado 2500 truck. approximately one month after the truck was purchased, it was being driven at about 45 mph and began to lose power while being driven. pushing on the accelerator made no change. the truck was taken to the dealership from where it was purchased, they tested the truck and reported no problem found. this problem has continued with the truck since that time. the truck has been in service on 4 different occasions, and the dealership reports that they have fixed the problem by replacing the wiring harness, replacing broken wires, replacing wiring that is broken inside insulation etc. this has not resolved the problem to date. the most recent incident occurred when the assistant service manager from the dealership took the truck out for a test drive (for a total of 120 miles), and he reported that the truck never lost power. i picked up the truck and drove it home and later that evening was driving the truck at approximately 45 miles per hour, when the truck began to lose power. several times when this has occurred, i have narrowly avoided being hit by other vehicles on the road because the truck loses all power within 20 seconds. *tr

 Speedometer is acting up and giving me wrong readings while driving. it rests at about 75 mph while i am parked, and while driving some times goes as high as 125+ mph when i am clearly going 60-70. 2003 chevrolet silverado with 51,000 miles. nothing significant happened to make this problem happen, as i was just driving on the freeway when it occurred. i have done nothing to the vehicle to attempt to fix it as i feel there should be a recall on this faulty part. *nm

 We all need to contact gm at www.chevrolet.com and complain. i purchased my 2003 chevy 2500 hd in nov. 2005. it had 32000 miles on it. the warranty ran out at 36000 and when i hit 38000 miles the problems started. the electrical system started acting up. i had went to leave and everything was dead no power at all. i would jump it and then it was fine for the first couple of times. the last time i jumped it, it cranked but i had no power it wouldn't move in drive or reverse and all the gauges went crazy. i disconnected the battery waited a minute and reconnected it and everything was working fine again. a week later the speed odometer went crazy and wouldn't go back to zero. now starting a few weeks ago the drive train is making a loud clanking noise and the rear wheels are wanting to lock up when i try to start off. these problems don't occur every time, but the drive train noise is getting worse from all the feedback i see on this web site i feel i would waste my time contacting gm. all of us chevy owners with problems needs to contact gm every day about our $30,000 and $40,000 dollar hunk of scrap metal. i hope mine will burn and i will not ever buy another chevrolet product again. here is there web site www.chevrolet.com. i have been calling the phone # on the web site, but it just stops ringing. you can send them e-mails and letters. *jb

 For what appears to be no reason at all, the speedometer needle will go 'ballistic', registering higher than traveling speed, and occasionally even pegging out. over a period of time, it will then drop back to normal operation. this phenomenon will occur in warm or cool temperatures, within 5 miles of starting, or well into a longer distance of travel. upon inquiry at several dealerships (i am a full-time driver and travel a lot), i have heard various reasons for this occurrence, the most prominent having to do with the cluster in the dash, and the 'cure' depends upon the person to whom i am speaking. at one dealership, i was told parts were on backorder for 7 weeks. at another i was told i would have to park the truck and wait for a third-party repair service to do that work. i would be unable to move the vehicle while waiting, as the mileage would have to be re-programmed into the repaired cluster. waiting time for that was estimated at 4-6 weeks! (as stated, i rv full time, and this is my only means of transportation.) customer service at gm gives the impression that ours' is an isolated situation (explain that 7-week backorder at the dealership to me again!), and therefore must be of little consequence to them! i am concerned from the safety standpoint, as it is impossible to know what one's speed is. (going too slowly can be as dangerous as going to fast--i fear being rear-ended as much as anything!) there must be more folks out there who have not complained, to account for the lengthy wait involved in getting a solution to the problem. please help. *nm

 My speedometer is not giving the right speed or sometimes, it doesn't even work at all. i still get my total mile on the odometer but not my speed. this is a low mileage, barely used truck and i have no idea how fast i'm going? sometimes it works but is still off and other times, it just stops working all together. if it is cold, it stops working and you hear a tapping noise coming out of the cluster. if it is warm weather, you get some response out of it but it is not correct. i was already pulled over for speeding when i thought i was under the speed limit. there are i believe, 5 different speed sensors on the truck and i don't know which one is not working. i am not alone in this! there are hundreds of people on chats and forums who are complaining about the same thing. why should i have to pay for these cheap parts? *nm

 Was driving down the freeway and my speedometer was showing that i was slowing down. my speedometer will work for a short period of time then it will start to show that the vehicle is slowing down. and soon shows that you are going 0 mph. after sitting for a few hours in park and not running, it might work. sometimes it never works again for a day. took it to the local dealer and they told me that they have had many others like this and they didn't know why it is happening but chevrolet has not recalled it yet. they told me it ranges from 2003- 2005. they have worked on every one of these years. the dealer told me they couldn't do anything for me except replace my speedometer cluster, for about 1000 dollars. without a speedometer is a big safety issue and i know that this is happening to other people. *nm

 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. *jb

 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. *nm
02/08/2006109185108/30/2004
 Dt*: 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,. *nm

 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! *nm

 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. *nm

 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.

 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. *jb

 Left turn signal causes the turn signals to act as hazard signals preventing other drivers from knowing the truck is turning left. there is a know recall coering this issue with 03 suvs and trucks, but chevy states it does not effect my truck. here is the recall from the internet. on certain trucks and sport utility vehicles, the driver wishing to signal a turn by moving the directional signal lever, (up or down) may cause the front marker/turn lights and rear turn lights to flash in a manner similar to hazard warning, rather than flashing on the desired side only. defect consequence: the driver may not be able to clearly signal their intentions to turn, change travel lanes, or potentially warn others of an impaired vehicle operating condition increasing the risk of a crash. remedy: dealers will replace the suspect flasher modules with a new flasher module designed with sealed relays and more durable contact material inside of the relays free of charge. the recall began on august 4, 2005. isuzu began mailing owner letters on august 4, 2005. owners may contact chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, isuzu at 1-800-255-6727, buick at 1-866-608-8080, and oldsmobile at 1-800-630-6537. notes: general motors corp., 05044

 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:(
