I called the 800 number and the lady told me that I am not covered for their special provisioning for this known problem. That their special provisioning only covers vehicles 7yrs/70k mileage. I have over 90k miles and they are not willing to cover me. I think this is crap! She was very unfriendly and unwilling to assist. I can’t afford to pay for this to be fixed. I will never buy another Chevy car I can’t believe there is no recall for this issue.

For all people dealing with the instrument panel failure please complain to the Better Business Bureau and the National Highway Safety Board. My speedometer and RPM gauge has failed completely and the oil gauge is pinned to maximum. There are so many complaints about this and no recall on this model but other models with the same problem have been recalled. Please complain and see if we can get this fixed.

Trailblazer EXT 5.3L V8

  • Automatic transmission

All of the gauges are randomly not working. What I mean by that is you can go out and start it up and drive away with the gas gauge and RMP gauge not working, then the next time you start it the gas gauge works but the speedometer doesn't work, then the next time the gas, rmp, oil, and so on. The only thing that is consistent so far is that when you go out and start the car and find an issue that issue will not go away until you turn off the car and start it up again. I was told that this is a bad instrument cluster and that it would cost at least $800. Because of the number of people having this problem there is no question that this should be a recall, but because of the economy being where it is and with GM filing Bankruptcy I don't see them caring enough to do it. The one auto company that is doing well on customer service and quality is Ford and I can tell you that because of this situation I will not be buying a GM again. I bought this car brand new so I know it was well taken care of.

There is no question that this is a safety issue and all we can hope for is that the safety commission will start to see all of the complaints on this one issue and force GM for recall this problem.

With as many owners of this style of vehicle and with the pick ups the same year that are covered by warranty with same problem and the Trailblazers are not covered I just don't understand why one style of Chevrolet the same year with the same problem have a recall and the other one doesn't. I own 3 Chevrolets and I believe in them and with all the problems the company has not selling cars it looks like they would be happy to fix this problem to keep their customers and their customers would praise them for their service. Problems like this are why people don't buy their products and go to other companies

Instrument cluster going crazy wasn't all the time early on now it is Had to have the ignition module replaced already now it appears the PCM is failing based on how the system gauges go crazy and dash display goes nuts. The fuel efficiency is dropping. I have been a GM loyalist but very displeased with the current GM response to an unGODLY amount of complaints on this vehicle. There are safety issues involved!!!!

It is a real pain !! First the RPM stop working. I didn't care much, but in couple of months the speedometer started to act crazy. It goes all around, the best is passing by the police showing that I am doing 110. I don't think the car can even make that fast !!! I check for recalls and so far doesn't seems to be one. If there is a cheap cost to fix this problem I will fix other wise I will wait.

I'd just like to add my name to the list of growing complaints on the 2004 Chevrolet Trailblazer's instrument panel problems. I was driving on the Interstate a few days ago and the speedometer just gradually dropped to 0MPH. Since I had previously heard of this problem I didn't panic. I pulled off to get some fuel and after I started the vehicle back up everything seemed to be working normal, until today. I was on my way to work and the speedometer turned past 120MPH and held steady no matter how much I sped up or slowed down. Now at a stop the speedometer is at 120MPH and continues clockwise as I accelerate. I really hope GM recalls this problem soon!!! I don't have $800+ to fix this. I'm assuming its only a matter of time before the other gauges screw up!

I bought a 2004 Trailblazer the other day and before I got home the Speedometer stopped working. So I took it to my mechanic and he did the computer check and came up with problem code P-0128. The next morning I took it back to the dealership and told them what had happened in the last 12 hours. They could not believe it. After reading this AutoBeef I can believe it. I wished that I had found this AutoBeef last week. The dealership said the repairs would cost over $800. and that they would pay for all of the expense and the deductible.

This makes me sick to read all the same problems on the 2004 Trailblazer. My instrument panel gauges all read zero this morning one week after replacing the battery and thermostat. This is a major expense I can't afford but I have to have transportation. Shame on you GM for causing such hardship. I guess I made a really bad choice in cars and can't afford a new one. I'll definitely be calling that 800 number to add my complaint!

The Gas gauge fluctuates so much I have to keep half to a full tank. One second it could say full the next totally empty. I have also noticed my warning lights go on and off so much I do not notice them anymore. My locks have been reprogrammed a few times and I still can't open all my doors all the time. I gave up on that one. My interior lights on the dash sometimes don't work. Now the pedal sensors need to be reprogrammed because my car is confused between the gas and brake causing me to accelerate when not expecting. All computer problems.

I bought this used in 2008 and it had about 96000 kms on it when I bought it. About a year later, the speedometer stopped working. The speedometer sometimes moves but not often and when it does move it is never right. GM should come good for this since there are a lot of complaints.

The main issue I have with my truck is that the fuel gauge fluctuates. From a full tank down to about 1/4 of a tank it's fine. Once it hits the 1/4 tank mark the light will come on on one trip and the next time I go somewhere it's back up to 1/4 or a hair below. Since i don't want to run the risk of running out of gas, I usually throw $20 in it. With $20 it damn near goes up to 1/2 a tank. What the heck is going on? Looking at the other complaints, this is an issue that definitely needs to be recalled asap.

The dealer will want to charge you to replace the entire gauge cluster. With a little mechanical know how and a soldering iron you can simply remove the gauge cluster and replace the faulty stepper motors for about $15 per motor. You can even get the replacement motors on ebay.

I also have a 2004 Trailblazer that the gauges stopped working. It started out with miss-reading the speed, as in reading higher than the actual speed. like going 120 mph when really going 25 mph. Now it is currently stuck with the needle pointing straight at neutral. Then just last week. My low fuel light came on. The next time I started the truck it was up to 1/2 a tank and as I drove it went to 3/4 then 10 miles later it slowly dropped back to 1/4 then the light came on again and then back to a 1/4 of tank.

This is an on going problem with these trucks. I know 3 other people with Trailblazers and 2 of them are having the same problem. The dealership told me it would run about $850 to fix and needless to say it has not been. They are off their brains. This needs to be a recall.

At first, it was only the fuel gauge that quit working. I have to use the trip mileage to be able to know when to fill up the vehicle. When I asked about it, they said it would cost over $550 for a new instrument panel. I couldn't afford it, so I kept driving without repairing it. Then after a trip, the speedometer messed up. Then again yesterday, the speedometer went out and I had to travel over 100 miles not knowing how fast I'm going. This is awful! I have one more payment on this vehicle. While I've had the vehicle, the engine light has come on consistently. One other problem I had shortly after I purchased the vehicle was the flashers quit working. That was covered.

battery went dead. when new battery was installed, all of my gauges are going crazy. was told by dealer this is not covered under a recall, even though my friend owns a 2004 Chevy full size truck and the exact same thing happened and it was covered under a recall. was told it will cost almost a thousand dollars to fix. after reading other complaints, i am hesitant to have it fixed, because of chance of it happening again.

after a month, two new batteries installed, a new alternator, taking it to three different mechanics and the chevy dealer where I purchased the car, it still does not start randomly. Also, the tachometer, speedometer, and battery gauge do not work at all. sometimes some of the other gauges work, but sometimes they do not. called chevy. all they said was take it back to the dealer AGAIN

The first time the tac went out, took it into the dealer and they said it only needed to be reset. They did this and it lasted two days. Took the vehicle back and they reset it again. Lasted two days and went out. Called dealer and advised the problem. They advised that a new instrument cluster will need to be installed. This will cost $500.00. I asked if this was a recall item, they advised that it was, just not my vehicle. If I had one, I would tell them to suck it! GM should fail. Any bail out money to them is shame on us.

  • Automatic transmission
  • 59,000 miles

My 2004 Trailblazer's speedometer began telling the wrong speed in May. It will say I'm going 80 when I'm at a stop. It sometimes will work every couple of weeks for about a day then goes back to telling the wrong time. At first it was telling the correct mileage, but a couple months later it stopped doing that. Now it says my mileage is 3770. In January the fuel and oil gauges also started not working. The needle is about a centimeter past the full mark all the time until it has about a gallon left then it goes to empty which is a pain and nerve racking because all the sudden the gas light will go on and I have to go straight to a gas station. I called Chevy's recall # 800-222-1020 to see if my model qualified, but the recall is only for 2002 and some 2003. They took my info and said they would contact me if there is a recall on my vehicle. I also filed a complaint with the Highway Traffic Safety Administration (I Googled it). It took about 15 minutes and there are a lot of people complaining about the same problems (more than 400). So I would suggest you do the same and maybe they will actually do something about it. The website is www-odi.nhtsa.dot.gov/ivoq/index.cfm or google it. To file a verbal complaint the phone # 888-327-4236.

Trailblazer 4.2L

  • Automatic transmission
  • 38,000 miles

The gauges on the dash are giving wrong readings on a regular basis. It started with my oil pressure gauge showing a low reading. I had it in the shop and they replaced the sending unit, though they indicated the pressure was fine. One week later, the pressure went off the scale. Then I noticed the amp gauge showing no charge, yet everything worked fine. A external voltmeter (after a 90 mile tense ride home) showed the battery to be charging at 13.9 volts. Again, gauge problems. After this, I learned not to trust the oil gauge or amp meter. As I was driving in a snow-storm, I noticed the speedometer was showing a speed 25 miles lower then I was actually going (using my Garmin). This could have caused me to speed. Luckily, I knew the gauges were causing mischief and didn't trust them. This is a serious problem as it can cause injuries if one pays attention to the gauge for speed. GM needs to do a recall on this.

My gauge problems began with the oil pressure gauge, which decided to pegged out one day. Took it to the dealer, who stated that the instrumentation cluster required replacement, which would cost me $600. I could live with a faulty oil gauge, so passed up the repair. We went on a 3-hour trip shortly thereafter and noticed that the battery gauge was also pegged. We just happened to have the TomTom hooked up for directions and noticed that the speedometer was 10-20 mph faster than the GPS speed. After closer examination, we realized that it was also sticking. This is a safety problem that needs fixed, but I'm having a hard time parting with $600 for the repair, especially considering that numerous others are experiencing similar problems. Sounds like a safety recall is in order. And folks wonder why everyone is going to Toyota to buy their vehicles...

had this vehicle since 2006...really no complaints till this problem occurred in October 2008. first the tachometer would show 7 or 8 grand or even redline while the vehicle was sitting still or in park. it would only drop to 2 or 3 grand when engine was off. it sometimes seems like it is working, but only once in a great while. usually it is somewhere other then where it is supposed to be. then just today my wife informed me the oil gauge is at 0. great. just what i need, another outrageous car repair bill that we cant afford. why does my 1970 gto seem to be the car that is outliving the 2004 trailblazer or the 1994 impala ss i own? new cars are supposed to be the more reliable cars at this time. why do we have to pays so much for cars that don't last? gm has always been my first choice of car. these car manufactures need to stand behind our investments and step up to the plate. this gauge problem should be a recall. this is a very dangerous problem.

Shame on you for not making this a recall! When a person is traveling the gauges are something we consumers rely on most! Put one of your loved on behind the wheel and have them try to guess how fast they are going. Maybe we should start sending you our speeding tickets! $500.00 may not seem like a whole lot of money to you, but when it it comes to me and my family in todays economy,its more than I have to spend on a default. Please consider recalling the gauges, it is a safety issue!

This started off with my RPM gauge not working and now it has slowly progressed second to my oil gauge, then my speedometer is still working as it feels like it...sometimes it registers off the charts and sometimes its 15-20 mph ahead of me. And now, yesterday after I filled up with gas, the gas gauge registered way past full!! I see where other consumers have had this problem, and if they were able to get Chevrolet to fix it, I have been looking for a recall but, not luck. I thought Chevy's' were "built to last"!! WTF!!!

First off...Go to the NHTSA website and file a formal complaint so hopefully enough reports will generate some push from the regulating agency on car manufacturers.

I have the same issue as so many other Trailblazer owners on here...RPM gauge quit functioning and then shortly thereafter, speedometer doesn't register sometimes for hours at a time while driving. This is a serious safety hazard for all of our families and all other motorists on the road. If GM can fix it for other models in their line, why won't they get off their rears and recall it for this vehicle as well?

I started out on November 26th at 9pm on what i thought was the beginning of an exciting trip to see my family for Thanksgiving. An hour within the ride i looked down to check my speed and it read that i was doing 120mph. My first thoughts was "WHAT IN THE HELL!"..now im wondering if my car will start malfunctioning and eventually stop running. I continued driving because i still had 7 hrs to travel to get to my destination. I looked again and the speedometer had headed south pointing straight down. This was very scary because i have to now travel 7hrs in the dark not knowing my speed or if something else would happen to my car. THIS REALLY NEEDS TO BE A RECALL!!!!

Also my sister gas gauge has stopped working on her trailblazer.

I have always liked GM cars and believe the small block chevy engine to be the best overall engine ever built. I may have owned my last GM product. I have a 2004 Trailblazer and the instrument panel is shorting out. Tachometer drops to 0 at times, volt meter goes haywire, and now the fuel gauge is bezerk! Can you imagine going on a 1,000 mile trip and not knowing how much fuel you have? It is frustrating. I called GM months ago and they said it wasn't under recall but my brother-in-law has an 05 denali with the same cluster and they recalled and replaced it! Crazy!

had the vehicle 4 years, i love the way it drives and the room, but about 6 months ago the speedometer and tach went crazy then quit working. now my voltage gauge don't work! from what I've found online, it's a cluster problem and I'm not the only one!!! recall! recall! recall!! where is it!!! i paid 18,000.00 for this vehicle and helped line a lot of executives pockets with my hard earned money. they are crying "bailout", with millions of our tax dollars. I'm suggesting if we help them, they MUST HELP US IN RETURN! RECALL!!! what i ASK for is so much less than what they are DEMANDING!

My speedometer went out 1/12 years after I bought it and was no longer under warranty. I check several places and its $500-600 to fix it. It started out where it would be off a bit so I would just calculate how fast I was going, then it would stop working for awhile then start working again. Now it faces straight down and will not work at all. The RPM gauge is a little off. Everything else doesnt work at all except for the gas gauge. The battery and cold/hot gauge NOTHING works. I cant afford to fix it and have been driving like this for 4 years. If I get pulled over that is a huge fine for it not to work. THEY SHOULD RECALL AND FIX THIS!!!

Ok, so I buy a "trusty" Certified Preowned Chevy Trailblazer. Two weeks after enjoying it....the MOH gauge and RPM gauge fluttered and stopped working. HMMM.....I called the dealer and asked about it. They checked my warranty....OOPS! It's covers everything but the gauges! So i travel myself down to the auto-mechanic. He slaps me with a fat bill of $568 to fix it by a CHEVROLET CERTIFIED MECHANIC at my local CHEVROLET dealership. So..I pay the price. Low and behold if it didn't happen again! I called the mechanic up and nothing i can do because it was only guaranteed for 6 months. So I contact GM. NO recalls for the THOUSANDS UPON THOUSANDS of complaining trailblazer owners who paid for the $30k truck but all those Suburban, Sierra, Silverado & Tahoe owners that paid $40k and up for their vehicles got recalls for the SAME EXACT ISSUE WE ARE HAVING WITH OUR GAUGES. Amazing what money can do for ya these days! Because my vehicle cost $10k less than Squeeky Joes, I'm screwed! JUST WANT TO SAY IF YOU FIX IT...IT'S GONNA HAPPEN AGAIN AND AGAIN AND AGAIN. MY SUGGESTION...DON'T BUY ANOTHER GM PRODUCT! THEY DON'T STAND BEHIND THEIR PRODUCT! WELL AT LEAST THE LESS THAN $40K ONES ANYWAYS.

One day we were heading to the airport and when I glanced down at my speedometer, it read that I was going 90 but i know i was only driving at about 40MPH because I was on a bumpy windy road that I wouldn't speed on. After a while, the speedometer made it's way back to zero and would work okay for about a month, then it went crazy again, reading 100 while I was at a stoplight. Now it is stuck facing down, overlapping the gears.
These days, I don't even look down at the speedometer because it doesn't work and it's pointless. When I took it to my mechanic, we asked him to give us an estimate and he said it would be somewhere between $500-600 to fix.
In the last month my RPM has been beginning to act up.....but that's another complaint. I just want to warn you folks that if you don't fix it, it may cause more issues, I'm not sure, but based on my observations, that's what happened on mine.

headlights pulse like a police car, ive had cars actually pull over for me also at the same time the alternator gauge would go down and dash lights would dim would. Chevy dealer would always fix it with a new alternator blaming it on that.i finally talked to a real good gm electrical tech i know and he said to have my dealer check the grounds on the trailblazer all of them they found bad ground wires on the left side frame under the driver they replaced the ends cleaned the frame and the problems gone also note my tech said they also seen problems with the grounds under the center console in the trailblazer
hope this fixs your problem P.S. THE GROUND PROBLEM DOES NOT SHOW UP ON THE DIAGNOSTIC COMPUTER THAT THEY USE DEALER KEPT USING THAT OVER THE YEARS AND KEPT TELLING ME WE CANT FIND THE PROBLEM (SO MUCH FOR COMPUTERS)

Whenever I drive at night the lights flicker and sometimes go out completely when I brake or allow the truck to coast. When I use the gas the problem resolves but since I have to stop sometime this isn't a good fix. The electrical guage on my dash fluctuates with the lights going from low to high and back again. I've taken into 2 dealerships but they "can't dupilcate the problem" I work nights so I am driving mostly during the night. How is it save for a young woman to drive alone at night without lights? This problem has happened since I purchased the truck and has not been resolved.
