 Tl- the contact owns a 2004 chevrolet silverado. the contact stated they received a letter approximately one year ago from the manufacturer stating that the instrument panel warranty was extended to seven years and 70,000 miles. in addition, the contact was advised not to bring the vehicle in under the warranty unless the fuel gauge had completely failed. the contact stated that the speedometer had been stuck at 120 mph. later, the speedometer independently dropped below zero and remained stuck there. in addition, the engine rpm gauge would fluctuate sporadically but the engine would not respond. the contact took the vehicle to the dealer and was told that the failures were not covered under the extended warranty for the instrument panel and was advised that the entire instrument panel would need to be replaced. the failure mileage was 116,000 and the current mileage was 117,000. kmj

 The instrument panel stopped working on my 2004 chevrolet silverado. i found lots of complaints on this problem online. when i called the local dealer to see about getting my vehicle fixed they advised even though the mileage was old it was 4 month to old to be covered by the fix. they know they sold vehicles with bad instrument panels but are not fixing the problem.

 Well i bought the 2004 silverado truck in june of 2011 and i noticed that the speedometer stutter a little bit going each way. then just recently i experianced the speedometer just stop working by getting stuck at 30mph. i pulled over the truck and turned it of to maybe reset the system but even with the trucked turned off the speedometer was still at 30mph. i tried hitting the dash a couple of times to see if that would work. it didnt work so i tried driveing some more and the speedometer said i was doing 90mph when i was only going 65mph because i had another person on the road tell me they were going 65pmh. i even tried to hit the brakes multiple times to get the needle to drop below 30mph. it parctually worked by making it go down but then it got stuck at 10mph even with the truck turned off. so i came home and checked the recalls for my model truck and year and apparently there was a recall for this problem but only for vehicles under 70000 miles which i think isnt right because its a failure with your electrical clusters that you know is there but wont fix which makes it not look good for you designers. i am a diesel mechanic and i would tell people that this is a safety hazard.

 I purchased a 2004 chevy silverado bring new from commonwealth motors and now have 85,000 and the speedometer is registering from 60 mph to 120 mph. it's floating all over the place. i have never seen anything like this. it's so dangerous not knowing how fast you are going. how can a 2004 vehicle have this problem. i am finding out there are so many complaint pertaining to this out there. gm has decided to extend some kind of warranty for up to 80,000 miles. i was told this from the service dept at commonwealth motors, but he would absolutely not repair or replace anything because of the mileage. he compared it to taking out an extended warranty for your refrigerator and something happening the day after it expired. you can't kill yourself in your refrigerator when your not sure how fast your driving. i had received a letter approximately 1 1/2 years ago stating your vehicle may later have a problem, but (in bold letters) do not take your vehicle to your gm dealer as a result of this letter unless you believe that your vehicle has this condition. why didn't i have the option to change it for preventable measures. no. they wanted me to wait and maybe i would go over their mileage when it did go defective. then they can say i'm sorry, too late. gm is admitting they have installed defective speedometer cluster and in a 2004 vehicle, they should be replacing it. i don't have 200,000 miles, i only have 85,000. can anything be done concerning this matter. *tr

 My speedometer, rpm gauge, and transmission gauge have all stopped functioning...basically everything on the left side if your looking at it. the speedometer hangs on 30 or 60 and if it does work, which is only occasionally it's very slow and clicks it's way along, so therefore it is not accurate at all. the rpm gauge gets all the way off the gauge and sticks, and the other one just sits there. why is there not a recall on this yet...it's too expensive to fix and very unsafe to drive! *tr

 On aug 13, 2008 at approx midnight our truck which was parked in our driveway started on fire. it did damage to the engine and we believe it started with the glow plug relay switch or something electric covered by power train warranty. today is sept 13th and we just received a ltr from gm that they are not taking any responsibility. we are frustrated and the truck is damaged and we do not believe we will be made whole as the insurance wants to total and pay only the market value which is much less than blue book. we are without a vehicle and gm has been less than reluctant to respond to calls, etc. the truck has been sitting at dealer for a month waiting for someone from gm to inspect to validate fire dept report and accept responsibility. i am disgusted with their customer service and the fact that you cannot talk to anyone with authority. this is their problem and they don't want to take any action. i found another individual had the same problem with their truck. our truck is like brand new. it was purchased brand new and it is a 2004 duramax with 46,000 miles in mint condition. can you help us? *tr

 My 2004 chevy silverado speedometer keeps sticking at 55 or 60 when i travel for more than 20 miles its really unsafe and ended up paying a 191.00 speeding ticket over this. my speedometer was stuck at 50 when i was really doing 65 and i didn't notice i told the officer but he said to have someone check it out. i am a fairly good mechanic also a electrician. i know it is the stepper motor in the instrument cluster. i just don't have the funds to fix it myself when i am paying speeding tickets this should be a definite recall i have read so many complaints over the internet. also talking with other mechanics that see the same problem on at least weekly basis. thank you *tr

 2000 miles after my warranty went out so did my speedometer it will work for about a week then register 60-100 mph even setting still. i contacted earl dunn in madison cause that is where i purchased the truck and the extended warranty that really wasn't extended. the warranty they sold me didn't exceed the manf. warranty . they told me at the dealer it was a additional 36,000 miles ,huh ,that's what i get for not reading the very fine print. now i can honestly see why american company's are going belly up and that's a sad thing. last gm for me. i contacted a dealer in carthage tn there service manger said they would have fixed the problem, no cost , but since it was purchased at another dealer he couldn't really do nothing about it. he also said it was a major problem for chevy/gmc, p/u's,avalanches,escalades,tahoes, but gm was doing nothing about it and they couldn't get new parts to fix it. the instrument cluster had to be sent off to be remanufactured.

 In june 2006 the truck was taken to pinkerton chevrolet because of a hot wire smell. the dealership said they could not duplicate the smell. an oil change was done at the same time. approximately 7 weeks later the truck shut off. my husband attempted to restart the truck to no avail. he left the truck in the off position and went for help. he returned 20 minutes later to find that the truck caught on fire in the cab. the dome light was on but the doors were shut. the dealership says they think rats got into the engine but there was no fire in the engine only in the cab. the truck is moved everyday. we have two other trucks and a camper that is stationary all the time and they have no rat nests in them. we have no tall grass around our house or in our yard. the truck sat at the dealership in the tall grass for a week before it was even looked at after the incident. my husband regularly does safety checks on the vehicles and never saw any rat nests, gnawing, or droppings in the motor compartment. the dealership is refusing to look at whether or not the supposed rats really caused the fire. the dealership says that my insurance needs to pay for it. the truck was at the shop a month before and yet there was no thorough check up on the truck while it was there. this is a very expensive truck to just go up in flames. the dealership is fixing the truck on the assumption that my insurance is going to cover it because they have no intention of doing it themselves. *nm

 I bought this truck in feb 2004 and it has been in the shop numerous times for wiring harness repairs. then when it is out of the 36000 miles warranty, it has problems again and the dealership then tells me they will need to replace the wiring harness at about $1500 out of my pocket and a rental fee. i throw a fit and therefore they decide to let me have the wiring harness on their behalf but i will have to pay labor and my own rental. after it was all said and done i was out $900 and don't feel that i should of had to pay that because if they had replaced it after it had been in the shop 4 times within 8 months i wouldn't of had to be replacing it out of my own pocket. i called and asked them to reimburse me labor and rental costs and they said no and the person who made the decision refused to discuss the situation with me. *jb

 New silverado the two batteries go dead in a few days of no use. after three service trips to dealer. they tell me not to leave the tow package switch on. so instead of fixing the short, they tell me not to use this option. i am fear this may cause a fire. also when i took a test drive all the silverado's on the lot were dead and had to be jump started. *jb

 Truck cut out while on the freeway; able to get it restarted. later while trying to get home it stalled in the middle of an intersection. chevy service dealer knew exactly what it was-- he told me it was due to a broken wire primary at coil connector. that this happens all the time. part was replaced at a cost of $141.37. if this part is defective why is not recalled? *tr

 November 10, 2007, i wrote the following letter to: general motors 100 renaissance center p.o. box 100 detroit, mi 48265-1000 certified mail number: 7007 1490 0000 9298 4767 to whom it may concern: i have received your letter regarding the 2004 model year chevrolet silverado whereby general motors is providing extended warranty on the instrument panel. general motors wrote: this letter is intended to make you aware that your vehicle could develop a condition where one or more of the instrument panel gauge needles may stick, flutter, or become inoperative. however, general motors also wrote: if the condition occurs on your 2004 model year chevrolet silverad within 7 years of the date your vehicle was originally placed in service or 70,000 miles, whichever occurs first, the condition will be repaired for you at no charge. frankly, i find the mileage restriction ludicrous! either the instrument panel is defective or it is not! moreover, if the instrument panel fails when driving, especially at night, public safety becomes an issue......... *tr

 My speedometer needle started to stick on a higher speed and not come down. it would return to zero if i started and stopped the engine multiple times. this condition gradually worsened until it was stuck on pegged, even when parked. i had no idea how fast i was going. also, the speed control would not engage. i had to stop the vehicle and turn off the engine, then proceed before it would work again. i took it to the dealer for the speedometer. they were aware of the speedometer problem and one person insinuated it was a very common problem. they replace the cluster (?). they would not allow me to have the old parts and charged me $450.00! i speak for myself and others with this problem,we need help! *nm

 After 15 months of operation, the speedometer started acting strangely and finally failing completely after 18 months. the vehicle was well under warranty. took it in and the dealer said that they had to backorder and the new speedometer would be in within a couple of weeks. that was 5 months ago. still no resolve to the problem. i haven't had a speedometer in 5 months. when i complained to gm, they said they would give me 12,000 miles and/or 1 year extra of warranty. what actually happened is they started the 12mos / 12,000 miles at that particular moment which decreases my originally warranty by 1 month and 4500 miles. *nm

 Instrument cluster on 2004 chevrolet 2500 hd starts going out and the speedometer and tachometer cannot be depended on. when this is happening and you have the cruise control on who knows how fast you are really going. i feel there should be a recall since chevy has them designed to where they generally go out just as the warranty goes out. why should we wait until this causes a wreck. *nm

 Trailer brake wiring harness. i recently purchased a trailer which required a electronic brake. after having the braking system installed by the manufacturer of the trailer i was informed of the problem with the braking harness on the vehicle. i then called the dealer for more information, they recommended i take it to another trailer dealer and have it looked at. that's when i found out that the wiring harness was only receiving 4 volts, the braking system requires 12 volts. *jb

 The connector to the fan blower motor resistor burned up and melted on my 2004 chevrolet silverado 1500. the technician that worked on this vehicle said that the connector shorted out, causing the resistor plug to burn up. he also stated that this was common in certain gm vehicles. chevrolet said there was no problem.*ak
