Problems with 2004 Chevrolet Silverado 2500 ELECTRICAL SYSTEM

Check engine light came on and "low engine power" flashed where the odometer is. this caused the rpm's not to go over 2800. code reader claims o2 sensors or throttle control module or catalytic convertor issues. we discovered it was none of the above. to fix problem change 3 relays located under hood in fuse box. relay #8864. then clear codes, should fix issue unless code persists. relays will cause a fire if not changed out asap.

Many of the vehicles in this family suffer from random electrical shorts and or poor electrical grounding relating to the drive by wire throttle actuator. the result is that the vehicle will go into 'reduced engine power' mode randomly. in this mode the vehicle will idle but not accelerate or drive. this issue is well documented on message boards with no consistent fix. this condition exposes an extreme hazard as the vehicle can loose power at any time. this is a serious safety issue that should be investigated. i have had my vehicle loose power on the interstate and on high speed 2 lane roads with no shoulder and heavy traffic on 4 occasions. numerous attempts to repair the issue have been unsuccessful.

I bought a 2004 chevy silverado from medved and i feel it has a problem and gm says it's working as designed. my problem is the message module led's are so dim they can't be read in the daylight and the instrument cluster has been replaced 3 times by medved to try and fix the problem. the p n r d d3 d2 led"s are just fine. they told me to take it to another dealership to see if they can fix it. i took it to [xxx] and a 18 year service tech said it doesn't get any better and gm should have sent out a recall but didn't. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr this could be a safety issue if you can't read the warnings and other messages that appear on the module while driving. *tr

Tl* the contact owns a 2004 chevrolet silverado 2500. the contact was driving 60 mph when the speedometer failed and indicated that he was traveling 90-100 mph. the dealer was contacted but the vehicle was not repaired. the manufacturer was contacted but would not provide any assistance. the failure mileage was 120,000.

2004 chevrolet silverado 2500. consumer states problems with replacement alternator *tgw the vehicle caught on fire which may have been due to a manufacturing defect with a replacement alternator that was recalled. *jb

Tl* the contact owns a 2004 chevrolet silverado 2500. the contact was driving at 45 mph when he noticed that the dashboard gauges were fluctuating back and forth. the speedometer was stuck at 110 mph. the dealer advised there was not a recall for the failure and any repairs would be at the contact's expense. the manufacturer was not contacted. the vin was not available. the failure and current mileages were 100,000.

Speedometer starting acting up by over registering my speed and now reads 120+mph no matter what my speed. it falls back to 50mph when i turn off the ignition. *tr

2004 chevy silverado instrument cluster sticks and reads a constant 120+ mph. started to stick at around 75 mph for a month. now is stuck on 120+ mph and will not move even when truck is restarted or flashing computer. *tr

The speedometer in my 2004 chevrolet silverado 2500 has begun intermittently showing speeds that vary widely and do not indicate actual road speed. the speedometer fails to return to zero at rest and has shown speeds more than 40 mph in excess of estimated actual speed. this seems to be a common complaint, although i have not yet contacted a dealer or gm. i believe there are two components to this problem: 1) i cannot rely on the speedometer reading; 2) this could affect the miles shown on the odometer or at least cast doubt on their veracity. the truck presently has just under 42,00 miles on it and has been relatively free of major defects other than recall items. *tr

My 2004 chevy 2500 instrument cluster has issues. on 12-24-07 on a family christmas trip my speedometer stopped working. i received a letter from chevrolet explaining that they would cover this issue for 7 years or 70,000 miles. it seems to me if they know this is an issue why there is no recall for this. after many days of calls to chevrolet customer service they tell me that this is not a safety concern and that there would be no recall issued. now i ask how can this not be a safety concern not knowing the speed you are going? the next issue i have that i also feel is a safety concern is the intermediate steering link. this again has slack and rattles. once again chevrolet states this is not a safety concern but how can you say that a part of the steering assy. is not considered a safety item? *tr

My speedometer is intermittently functioning. gm says that i have too many miles on my vehicle to pay for the repairs. this is a 2004 chevrolet silverado and gm has already extended the warranty on this item for 7 years or 70,000 miles. this is an electronics problem and mileage should not be a factor on it. the mileage has no bearing the electronic functionality of this device. it should be time and time only that dictates the life of this component. *tr

Intermittent and erroneous operation of the speedometer in my 2004 chevrolet silverado 2500 diesel truck. the speedometer frequently indicates the wrong speeds, at time over +100mph. at other times, indicates speeds less than actual or freezes altogether. gm refuses to acknowledge issue or offer to repair. this is a serious safety issue and can result in driving at speeds above or below posted limits. *tr

The speedometer works intermittently and i found myself going faster than the speedometer registered. going around a turn i was forced into the other lane of traffic do to the excessive speed. *jb

The speedometer in my 2004 silverado has started to malfunction. it does not show the speed of the truck on any consistent basis. it will start out at 30 mph and increase correctly then reset it self 60 mph andthe lowest point. it is dangerous. i researched several online discussion boards and there are many complaints out there. my dealership wants $600 dollars to replace the instrument cluster and the truck will not be drivable for at least a week while a new cluster is programmed with my mileage at the factory. this lends itself to many people not wanting to get the cluster fixed and leading to safety issues. *tr

Electrical malfunction/instrument panel. *tr

I have a 2004 chevrolet 2500 crewcab pickup. some where between 80,000 and 90,000 the speedometer began giving false readings. sometimes it appears to work correctly, sometimes not at all and yet other times it is clearly giving an incorrect reading. *tr

Speedometer working erratically. stays on zero, or reads lower than correct speed. it started working sporadically about 2 months ago, sometimes works, and sometimes doesn't. current mileage 38290. *tr

Tl* the contact owns a 2004 chevrolet silverado 2500. while driving 65 mph he placed the cigarette lighter in the ash-tray. next, smoke was expelled from the cigarette lighter housing. he pulled over to the side of the road to inspect the vehicle. upon inspection, he saw flames underneath of the hood near the fuse box. the fire department extinguished the flames. a police report was filed. the vehicle was towed to a collision center. the cause of failure has not been determined. the failure and current mileages were unknown. the vin was unavailable.

Tl* - the contact owns a 2004 c2500 chevrolet pickup. the contact stated that the speedometer hadn't been working for at least six months. the speedometer was stuck at 25 mph, even though the odometer was registering the mileage correctly. the problem originated in the instrument cluster. the vehicle was part of a construction company's fleet which included chevrolet pick-up trucks from 2003 - 2005. seven out of the 40 trucks have had problems with the speedometer failing. the contact stated that weather was not a factor in the failure. the failure mileage was 50,000 and the current mileage was 85,118.*ak consumer states a 20% failure rate on speedometer sticking. update *4/23/07 tr

The speedometer of my 04 chevy truck is not functioning correctly. it stays on 0, goes up way over the speed i am traveling and then sticks at various speeds. i have seen at least 100+ complaints on various google sites. most noticeably this one. http://www.topix.net/forum/autos/chevrolet-avalanche/tji11lgm9554merna/p3#lastpost.*jb

I have a 2004 silverado 2500hd(c/k) with 51,000+ miles. this problem has been occurring for several weeks and just started as i was driving the vehicle on the highway. the speedometer operates erratically by showing various speeds such as 80 mph while i am driving 25 mph or shown 120 mph while i am stopped. at time it might work properly but then jump to 60 mph while i am driving 20 or while i am sitting still. my dealer is well aware of this problem and will repair it for $580.00 i continue to drive using the tachometer to gauge my speeds and speed controls to maintain speeds while in mountainous or hilly terrain. *jb

2004 silverado truck speedometer malfunctioned. *jb

Digital instrument panel failure ( speedometer, fuel gauge, rpm gauge & oil pressure gauge all malfunction at 50,000, now at 81,900 miles. we received a recall letter a bit late. the recall was up to 70,000 or 7 years. called gm when recall letter was received dec.17, 2007. told us it was too late to fix because of our mileage. if only we would have received the letter way earlier. now gm can not fix the problem for us, unless we pay out of our own pocket! and they knew that the problem existed! *tr
