 The speedometer fluctuated over a period of 2-3 days, then stopped working. i called a mechanic and was told this is a known problem with this vehicle and that there was a campaign. unfortunately, this campaign has long expired. this is an expensive safety issue because the driver cannot tell how fast the vehicle is traveling. it should be a safety recall. *tr

 I ad no idea that this was an on going issue with the 2004 tahoes until a co-worker mentioned he had the same problem and then when i had a smog check done this year. i noticed about a little over a year ago that my guages were not working. didnt really look into as, i have regualr oil changes and check my levels regualarly too. but recently my speedometer doesn't read the speed correctly. it's now a permanent issue and i will have to replace the cluster panel completely it's a serious safety issue and i cannot believe gm will not recall for this item! how many others out there have the same problem and just like me, did not know it was an issue!

 I was driving on the highway when i glanced at my guages. the tachometer reading was below zero. then suddenly my speedodometer started slowly falling from 65 to 70 mph to just below zero as well. still driving. about 20 minutes later. the speededometer started to slowly rise. finally it stayed steady at about 35 mph. this created a problem. because i wasn't going 35mph on the highway. during this time, i tried not to increase or decrease my speed. i went with the flow of traffic. because, obviously, it was a safe rate of speed at that time. because the tachometer wasn't working too. the approximate calulation of my rate of speed. could not be ascertained. speed is a significant threat to public safety. whether it be the regular streets throughout your town or the interstate highway. another reason to consider this a public safety issue is. someone maybe driving faster than the speed rating of their tires. because of instrument panel malfunction. the risk of serious tire issues have now increased. this is a direct safety issue. through some research of my own. i found that alot of the effected vehicles. started having this issue after 70000 to 80000 miles. gm's attempt to rectify this safety hazzard is lame at most. 7 yrs 70.000 miles. these numbers were picked so they could keep their costs at a minimum. we, the consumer, are being forced. to take it once again. from the big businesses that refuse to take responsibility. for the very dangerous issues of which they created! has anyone figured out how many suv's have been or will be effected? how many of them are or will be on the road? also, once the instrument panel cluster gets replaced. the odometer & hour readings need to be reset. this opens the door for a new set of problems. odometer fraud.

 I bought this vehicle brand new in 2005. after appox. 5 yrs, the instrument panel started slowly not working. at first it was the speedometer, then fuel gauge and now the entire instrument panel is useless. not one gauge is working. i have researched and found the same issues with the 2004 chevrolet tahoe. i, for one, see this as a dangerous situation as well as completely against the law to be driving a vehicle without a speedometer. this is now the only vehicle that i have and i have to depend on this vehicle to drive my family around in. i don't have the means to have this issue fixed and due to the same issue with many of the same vehicles, i think chevrolet should be held responsible before someone gets either stranded or hurt due to their negligence.

 2004 chevrolet tahoe reduced engine power. occurs intermittently and only allows you to go about 25 mph. very unsafe if on a highway. gm dealer replaced the faulty wire harness and plug that plugs into the throttle body. also replaced throttle body itself.

 When air conditioner is running, air coming from driver's side vents become extremely hot while passenger's side remains cool. i cannot determine any specific conditions that made this occur. it seems to be totally random. the hot air is not warm air or pretty hot air, it is extremely hot, hotter than a hair dryer produces at its hottest. i report this because it is obviously a safety hazard and, judging from complaints showing on internet blogs, it is fairly common. apparently chevrolet is admitting no responsibility for this failure, even denying that it is a common problem.

 The voltage meter bottomed out while driving back in 2008. it alternated between registering correctly and then incorrectly until dec 2009 when it bottomed out and stayed. i have no idea what state my battery is in because of this. i've had it checked out twice by the dealer. the first time, in dec 2008, the meter worked just fine and the repairman could not get it to bottom out during an 18 mile test drive. the next day, it dropped below the last reading possible on the gauge and i drove it right back to the dealer. they told me that the entire instrument panel would need to be replaced. the tahoe had over 100,000 miles on it so it would not have qualified for the proposed class action settlement filed back in 2008. *tr

 On this date the speedometer and battery gauge began to go haywire, at first they began to jump up so it looked like i was driving faster then i was down the interstate. the next day when i drove my tahoe the speedometer kept getting higher and has maxed out over 120 mph, and the battery meter well over 19 volts and they do not move anymore. i now have to rely on a portable gps in my car to estimate how fast i am traveling. i see there was a class action lawsuit on this, but i am 3,000 miles over the 80,000 required to get a replacement gauge cluster. *tr

 2004 chevrolet tahoe. speedometer failure at around 80,000 miles. i've been running on the speed indicator of my gps for the last 20,000 miles. speedometer failures, due to faulty equipment, should be repaired in a recall by the manufacturer. the silent recall issued in 2007 never made it to me and it was only for cars under 70,000 miles. speedometers are safety equipment. they shouldn't fail as often as the 2004 model year general motors vehicles are failing. there are way too many people having to spend four-hundred to six-hundred dollars on a repair that should be general motors responsibility. *tr

 The speedometer on my 2004 tahoe does not give accurate speed readings. it said i was doing 62 miles an hour on the highway and i started passing every car on the road. i slowed down and then it never got above 15 miles an hour and i was on the highway. after shutting off the tahoe for a few minutes it worked again. this happens regularly if i drive the car for more than about 30 minutes at a time. *tr

 Wow! i just got off the phone with chevrolet about my speedometer not working at all. the rep stated this was not a recall but an extension of the warranty for the cluster if your vin# falls w/in a certain range. mine falls w/in the range but i'm over 80,000 miles and i bought the car used so had no idea about the wty extension. this makes no sense to me the cluster / speedometer is not an added feature or accessory, but mandatory on all vehicles. in other words no vehicles are purchased with out it. why is this not a recall it is a safety issue! there was a lawsuit on this, but only extended the warranty mileage, what???? it is defective no matter what the mileage, recall it before someone is seriously hurt due to an accident. i guess until it's recalled we can just guess what speed we are going, that's legal, right? help asap!!!!! *tr

 Speedometer registers 80mph at complete stop, 120 mph with movement. problem did occur without warning. at this time not repaired because i do not have $500. i think it is a safety issue and chevrolet should pay for repair even in my car is over 70,000 miles (is 83,000 now). i think we all want to save american car industry (with the help of taxpayers money), but we need to send the message to these people that they should be making reliable cars. please we need a recall for the problem. i do want to keep buying american, but you need to help us out. *tr

 I was driving down one of the busy roads in manatee county, and the back hatch glass of my 2004 chevy tahoe blew off of my car. it went air born and landed in the south bound lane almost on top of a car. if the car had not slammed on its brakes and swerved, it could have killed someone. i contacted the dealership, and the will not fix the problem. the hinges are still attached to my vehicle and the insurance company wants a $500 deductible. i know i have been online researching this kind of incident and i am not the only person to have this problem. i feel like it should be a recall before someone gets killed. it is not normal for a 4 year old vehicle to have its glass blow off. *tr

 I have a 2004 chevy tahoe with 87000 miles on it. problem is internal gauge cluster defect. in other words, the speedometer doesn't work. chevy/gm admits that certain vins had defective clusters installed (including mine) yet they will not recall them and/or replace them unless the vehicle has less then 70000 miles on it. the fact that this is a defective part and not just normal wear and tear and also that thousands of chevy/gm owners are experiencing the exact same problem should constitute a recall, regardless of mileage. there are speed limits set on all roads because it is unsafe to drive at too high of a speed. if we could all accurately judge how fast we were going we would not need speedometers. however, we do need them and when they all the sudden your speedometer starts going crazy (i.e. show your speed as 120 when you are in fact doing 30 or showing it at 35 when you are doing 75) it becomes a safety concern. the dealership where i purchased my car wants $575 to fix their defective part and gm/chevrolet has told me sorry, can't help you. *tr

 Instrument panel malfunctions by sticking while driving and not returning to zero when the car is turned off. in order to get the speedometer to zero out you have to turn the car on and off until the needle drops to zero. other times the instrument panel fails to register any values. i called chevrolet customer assistance center they referred me to the dealership which wants to charge me $ 500 for the part and an amount to be determined in labor ($200-300) to replace the instrument cluster. this appears to be a known defect for model years 2003-2007. several complaints have been filed in court. northern district of ca. one such matter. hundreds, if not thousands of defective instrument panels have been cited by the case filing and the listing on several public websites that include the nhtsa website. the nhtsa cites in reports that in 2005 30% of accidents leading to fatalities are speed related crashes; the same reference lists 13,113 lives were lost. considering this assessment by the nhtsa - i find this matter not subject to full recall or further detailed investigation an alarming issue. due to the instrument panel being a vital measuring device for the operator this becomes a significant safety and concern for all consumers who are on roads where these vehicles are used not just the owners. *tr

 Tl*the contact owns a 2004 chevrolet tahoe. while driving approximately 25 mph in inclement weather conditions, the speedometer displayed inaccurate readings. the failure occurred without warning. the authorized dealer was notified of the failure and an appointment was scheduled for repair service. the vin was unknown. the failure and current mileages were 42,515.

 Tl*the contact owns a 2004 chevrolet tahoe. while driving approximately 55-60 mph on normal road conditions, the four wheel drive activated without assistance. the four wheel drive mechanism failed to respond when the contact attempted to deactivate the system. the four wheel drive warning indicator illuminated intermittently on the instrument panel. the vehicle was taken to an authorized dealer for inspection, but they were unable to determine the cause of the failure. recently, the front driver's and passenger side seats failed to recline backwards. in addition, there was water leaking from the sunroof near the passenger side sun visor. finally, the passenger side power window and heated seat failed to operate. the vin and mileages were unknown.

 Tl*the contact owns a 2004 chevrolet tahoe. the contact received a notice from the manufacturer for the instrument cluster, which advised her to take the vehicle to the nearest dealer for service. he was not experiencing any failures at the time the notice was received. approximately one month later, the speedometer, heat control, fuel gauge dial, and other instrument panel indicators failed. the speedometer displayed a higher speed than what was actually being driven. at startup, the speedometer would read approximately 70 mph and then later register 120 mph when the vehicle was in motion. the dealer advised her to call the manufacturer. the manufacturer stated that the vehicle exceeded the mileage requirement; therefore, they would not assist with the repairs. the dealer stated that the repair would cost over $400 for the part alone. the vehicle has not been repaired. the current mileage was 78,323 and failure mileage was approximately 77,000.

 Well where should i begin, the first problem was the clunking of the front end when going in and out of driveways,the first steering shaft was replaced, a couple of months later the speedometer started making noise,that was replaced,then the clunking noise reappeared, this time it supposedly needed to be lubed, it was fine, however noise reappeared, then the second shaft was installed,the tire sensor light intermittently comes on when ever it feels like it, and tire pressure is normal, now the windshield wipers will not shut off when it rains except when you turn the vehicle off, however they come back on when you restart the car after hours of sitting, my wife is expecting our second child and also drive my 5 year old in this vehicle, this car is piece junk, gm needs to take back pride in there craftsmanship step up to the plate like there consumers did and fix this ?!@#$%! they need to extend there warranties because there cars do not last as they mislead you to believe!!! *tr

 On october 27th, the speedometer on my 2004 chevy tahoe began to stop working. my vehicle has 49k miles on it. the speedometer gets stuck at various points and will peg out at over 120. on many occasions, it will not come off of zero. if you turn the car off and restart it, it will drop the needle about 5 mph, but will never zero itself back out. i called the dealership (bill heard chevrolet, collierville, tn) the day that it occurred. i was advised that this was a common occurrence and was a problem with the instrument panel cluster. i was also advised that it would cost around $600-$700 to repair. after doing some research, i have discovered that this seems to be a defect in gm trucks and suv's. it is extremely dangerous! i asked the dealership if there was a recall and was advised that there was not. this is not just happening to me. i truly believe that gm should issue a recall to have this instrument panel repaired. people expect reliability when they invest this type of money into a vehicle and they are not getting it from gm or it's parts. *nm

 2004 tahoe speedometer is pegged full scale while parked in driveway with engine off. noticed several others having same speedometer related problems on internet forums. this is a safety issue that should be addressed immediately through a recall by the manufacturer. *nm

 Started vehicle november 14,2006 speedometer is showing at between 70 mph and 120 mph when at full stop. unable to figure out how fast i am going. internet is showing that a lot of gmc suv and truck owners from 2003-2006 are having this issue. dealers and mechanics are charging between $600-$800 to repair. *nm

 The speedometer started going way below the actual speed i was going. i'd have to turn the engine off and restart it and keep doing this until it gets back to normal. this went on for several weeks where it was fine, then it would drop below 0 at a stop sign, then would show 10 mph when i was actually doing about 35. now it's doing just the opposite. the other night i looked down at the speedometer and almost panicked because it said i was going 90 mph! i was actually doing around 50. this is a very serious safety issue and gmc should recall. *nm

 My husband and i own a 2004 chevrolet tahoe with 30,000 miles currently on it. we were driving home from supper last night when our speedometer quit working. we were doing 65 mph down a local highway when my husband looked down at his speed and the speedometer read 35. we stopped at a red light and the speed dropped to 0. when we accelerated, the speed stayed at 0 when we were doing at least 35. we then pulled over, turned the car off, recranked the car and then began driving. still nothing. i have to say that this is definitely impacting our safety. we have no idea how fast we're driving. i googled the problem and found around 100 other gmc/gm car owners with the same problem. they are stating it costs between $500 and $700 to repair the problem and many times the problem still exists after the repairs. we have not contacted our local dealer because it is the weekend. we plan to call on monday morning to find out the cost to fix the problem. *nm

 Our tahoe has 46295 miles on it. last week, the speedometer became erratic. it sometimes works, but often shows speeds of 50-80 mph while the truck is in idle, and much higher when the truck is moving. after talking with many dealers, repair shops and other gm drivers, this is apparently a common problem that has not been addressed by gm. apparently, the issue is with the instrument console, and other gauges may or may not be working as well. this is both a safety concern and a vehicle concern, as i may not know my correct speed, level of gas, etc. *nm

 I have a 2004 chevrolet tahoe z71. at 40,500 miles the speedometer has started acting erratically, registering speeds up to 70 mph when the vehicle is at a standstill and registering a variety of speeds (none of which are correct) when the vehicle is in motion. my dealership insists that they have never heard of this problem before, however, i have seen on various web sites where there are literally thousands of owners of tahoe and yukon that are experiencing this problem...it is unsafe. *nm

 Speedometer is acting erratic, sometimes showing 35 mph when actual speed is somewhere around 70 mph. other times it shows 0 mph. i'm concerned about this and wonder if there are other problems. *nm
05/01/200654000802/02/2004
 Speedometer suddenly began to register incorrect mph. 0 mph sometimes is 30 mph or 40 mph or up to 70 mph. this happens suddenly you will look down and it will show you are going 110 mph when you are really going 60-70 mph. took it into the deal and was told they have had more than several of this same problem. cost to repair was going to be approximately $500, was told no recall has taken place, but they believe this was a defect and we should keep the receipt. we decided at this point to hold out and see if there is a recall as the speedometer works correctly approximately 50% of the time at this point. *nm

 The speedometer on my 2004 chevrolet tahoe broke suddenly while driving. it went to a 0 speed of 40 mph. in other words, while moving at 25 mph my speedometer read 65 mph. i had to immediately slow down and was forced to move off the roadway because i was a hazard to other traffic. this was the second such incident. in january 2005 the exact same thing happened as i was traveling at the posted speed limit of 70 mph. i slowed for traffic and as i accelerated back to the posted speed limit my speedometer read over 100 mph. i did not know my speed and was forced to pull to the side of a major freeway. that speedometer was replaced under warranty. however, the replacement only lasted 32194 miles and 15 months. besides the obvious danger in having a speedometer fail suddenly, there is the inherent concern that even if i was involved in even a minor fender-bender, the police investigating the accident would inaccurately find i was driving 40 mph above my actual speed and the burden would be on me to prove otherwise. an almost impossible task. *nm

 My odometer stopped functioning on my 2004 tahoe z71. i brought it into the dealer under warranty. the dealer advised me that this was happening to all of the tahoe's and they were back logged trying to get the parts. it took over a week to get my tahoe back. the dealer said that they repaired my cluster. the hour meter has 279 hours less now than it did when i brought it in. the mileage had 4 more miles on it. i called and advised the dealer that the hour meter had 279 hours less and asked him if they repaired the cluster or replaced it? he said they repaired it. so i called my brother in-law who's been a mechanic for chevy for over 29 years. he said that they had to replace the cluster and just reprogrammed the mileage and hours. why would the dealer make a false statement to me and tell me that they repaired the cluster when they must have replaced it? also, why hasn't this been a recalled by chevy? it's a safety hazard and is happening to all the tahoe's. i have only driven it home, so i can not tell you if the problem has been permanently corrected.*jb

 When vehicle was left in the rain, the speedometer would become inoperable. dealer replaced entire instrument cluster at $350. dollars. this involved partial pulling of dash to access. three weeks later the headlights stopped working. discovered that the sensor mounted on dash had fallen inside the dash. dealer claims that at the same time sensor un-attached, both headlights burned out simultaneously. they will not take any of the blame, and consider all events to be unrelated. *nm

 The driver's seat moves forward unexpectedly when the button for the heat is turned on, making the ability to see the mirror for the blind spot difficult. the doors locked on their own, which prevented entering and exiting from the vehicle. the manufacturer was contacted and was aware of the problem. *ak the memory module that controlled the drivers seat, mirror, locks and foot pedals, did not stay in memory and would go out of control intermittently while the vehicle was in motion. the consumer would become unable to reach the pedal, gas pedal, the mirrors collapsed and had been locked out of the vehicle on several occasions. *sc *jb
