Speedometer started to act erratic at about 40k miles. Now at 72k miles, does not work at all. I just spent $200 trying to repair, only to find out after that failed, that this is a common problem with gm. How can they justify recalling the tahoes, avalanches, etc, for the same problem, but leaving the trailblazers out of this safety recall?
2004 Chevrolet Trailblazer EXT electrical complaints
Page 5 of 6: complaints 101 to 130 of 145, newest first, as owners wrote them.
2004 chevy trailblazer v8 ext speedometer acting funny complete stopped shoes going 30. It reads faster than I drive so I have to figure out the stopped speed to figure out how much fast I am driving. Internet has many complaints about the same issue and similar ones like tahoe has been recalled.
No previous problems with panel. Problem occurs frequently. Tachometer quit working correctly...goes completely to opposite end of gauge. Took days before it went back to normal location. Speedometer does not work correctly...continues to climb to higher end of gauge....reads above 30 even when standing still. Goes down after repeatedly shutting off and restarting engine. Whirring sound made when starting or stopping engine. Contacted chevy dealer repair shop, they are fully aware of situation, advised it will get worse and will eventually stop working at all. No parts are serviceable, needs to be sent out for repair, could take anywhere from a day to a week or more depending on the parts needed. Plus there is the additional cost of having it read by the computer for the correct part(s). My car will be inoperable soon according to dealer, unsafe to drive, situation needs immediate fix.
I own a 2004 chevrolet trailblazer north face/ext. The speedometer has been giving me problems for some time. At first it would malfunction from time to time. Now the fuel gauge has stopped all together. When I started investigating this problem I found out that it is a common problem with this make and model vehicle. I also found out that chevrolet has another vehicle, "chevy tahoe", that has had the same problem. Why there is a recall to fix the tahoe and not the trailblazer ext. Is very interesting to me. I have gone as far as to take a look at the tahoe instrument cluster and saw that they are very alike. The vehicle recall to replace the instrument cluster on these vehicles should be sent out asap. If you take a look at the complaints on the internet you will see that this is a problem that many trailblazer owners seem to be having. You will also see that the tahoe complaints, "for which there is a recall", are identical. Thank you; patrick
We were traveling for the holidays and noticed that the RPM gauge stopped functioning properly. It was pointing below zero. Then, last week the problem spread to the gas gauge and the oil pressure gauge. This is a potential safety hazard.
Several times that I've been driving the trailblazer, the speedometer goes crazy and says that we are traveling at a much higher rate of speed than we are. Like if im going approx 70mph, it states we are going about 110mph! This is definitely a safety issue! And it has never been a recall?
I own a 2004 trailblazer ext and a couple of months ago the RPM gauge stopped functioning and doesn't even register. Less than a month later the speedometer started malfunctioning and many times doesn't even register a speed while driving for several hours. This has been a daily occurrence every time my wife and family get in the vehicle. This is a serious safety hazard for my family and for anyone else we may pass on the road. I know from reading multiple other complaints across the internet that this is not an isolated issue and that gm has already recalled the console cluster on several other models having the same or similar issues. When are they going to be held responsible for also recalling the same problem on this vehicle make?
One day I was driving down the road at about 40 MPH, but when I looked at the speedometer it was reading 90. For about a month the speedometer never reached zero and performed normally. One day it finally did reach zero and acted properly for about a week, then began acting up again. Since then, it has gotten stuck pointed down and does not move at all. Also, my RPM began acting up as well. Now it starts below zero and only moves occasionally. This is a major concern for me because I can handle not knowing the exact speed of my vehicle, but not knowing the RPM also makes it difficult because I have no real way to determine my speed. This is a dangerous issue that must be addressed. I have a friend with a trailblazer like mine and he has a similar problem. Speedometer doesn't work. Online I've also found hundreds of people who have this same problem. Gm must correct this electrical glitch!
The instrument panel on my 2004 chevrolet trailblazer has gone out. My speedometer, oil gauge, and fuel gauge are no longer registering the correct information.
Speedometer has completely stopped working. Started out intermittent.
Total failure of entire gauge cluster around 54000 miles 600 dollar repair was told that it shorted out and melted the connectors.
I started to lose the high speeds on the fan blower. In checking the internet I found this is a common problem for g.m. The problem is the blower motor resistor. When I went to replace this part I found that the whole wiring harness had been burnt to. It got so hot that it melted everything. The fuse for this did not even blow. This could have set the truck on fire. It is funny how the parts to fix this has much thicker wire. The parts in total was around $118. Thanks to a friend I had no labor cost. If I would of taken it to a g.m. Dealer for sure they would of wanted over $300. G.m. Knows they have a problem and are doing nothing about it. I feel this is a serious matter as it could of set the truck on fire.
I have many electrical issues with my 04 trailblazer from my window lights on the drivers door and the passenger door. I have had my radio replaced because it melted one of my cds. My head lights work when they feel like it same with the rear wiper. It has stalled out in traffic on me. I have also heard that in most 2000 to 2006 trailblazers the reason for the electrical problems is because water is running down the passenger side door into the dash and hitting one of the main wiring harnesses causing it to have many electrical issues. I heard this from someone who has an 06 trailblazer that just had it a replaced for $700.00 to fix and was told that it will just have to be replaced in a few more years because they cant fix the problem.
Speedometer freezes and you can't tell how fast you are going. Happens quite often. Brought it in, but they were unable to diagnose the problem as it wasn't happening at the time.
We have a 2004 chevy trailblazer, that originally began with the speedometer appearing to be stuck for a few days, would gradually decrease. Followed by the RPM having the same problem. Today, 11/28/08, all gauges lit up, warning bells rang, and then the entire instrument panel shut down. There was a recall for the silverado for the same year, but trailblazer owners are required to pay the repair bill for a faulty instrument panel. Being unable to know your speed, how much gas you have, or if your running low on vital fluids seems to be pretty dangerous to me. The fact that gm will repair the silverado, but not the trailblazer despite the fact that they are both in the "truck" category is ridiculous. It seems to me that any one of these problems can lead to death or injury of the occupants of my vehicle, either by fire, stalling in traffic and being hit by another vehicle at a high rate of speed, or because of the inability to ensure that my vehicle is operating with the proper vital fluids, as well as maintaining a safe rate of speed. My teenage children also drive this car on occasion, and though they've been driving for 3 & 4 years, they do not have enough experience to operate this vehicle safely. There was a recall for the brake lights, how can they justify that when people are driving around without properly working instrument panels? The solution being offered is for the consumer to pay at least 500.00 to repair something vital to the safe operation of the vehicle, but gm will replace the taillight/brake light that costs pennies on the dollar.
The speedometer on my 2004 chevy trailblazer is not working properly. I never know what speed I am going. It reads 120 MPH when I am at a red light! I'm constantly in fear of being pulled over by police whether I'm in the city or out in the country because I don't know if I'm following the speed limit. I took it to the dealership and they told me the whole dashboard needs to be replaced. The price of the part is @ $280 plus labor. Some of the interior lights have burnt out and labeling of knobs have faded. The hub caps on the 17" wheels aren't secure enough. They come off easy when driving through water. I lost them during a storm and had to replace them when I saw they were missing. Of these, what worries me the most is the speedometer as it is important for safe driving.
I own a 2004 chevrolet trailblazer ext. In nov 2007, the speedometer and tachometer started acting erratically. The tachometer would seem to stick and the speedometer would register either grossly over or under my current speed. It sticks when trying to accelerate after a deceleration. I have been able to get it to reset only after turning the engine on or off several times consecutively. I have been going down the interstate at speeds of 70+ (within legal speed) and the speedometer will show -5 MPH. Also, I have been going approx. 60mph and the speedometer shows 90+MPH. I took it to the dealership where I purchased it in nov 2007 and at the time, their instruments couldn't detect a problem mileage at time of failure approx. 104,000 (had a 100,000 warranty). They charged a $100 diagnostic fee to tell me they didn't see a problem. Current mileage is approx. 134,000. I have not had the problem fixed.
Speedodmeter sometimes work sometimes not working or not working at all.
Automatic transmission shifted out of third and would not shift back while I was on the freeway. Dealer said a transmission flush and fluid change would fix it. After performing flush dealer transmission was shot and needed replacement. Instrument cluster functioning intermittently, speedometer works at first and then slowly goes down to zero.
Rpm's and speedometer to not read correctly.
Tachometer failed and the speedometer acted sporadic shortly thereafter. I never have an accurate speedometer reading on my 2004 trailblazer that only has 50,000 miles. I am in the process of finding a repair shop or getting my dealer to fix the problem at a discounted rate or free.
The speedometer on my 2004 trailblazer works intermittently. This began in the fall of 2007. Sometimes it works seemingly fine. It will then freeze on a speed. Sometimes it will register a speed that is obviously incorrect. For example it will register a variable speed that is 20 or more MPH faster than we are traveling. It sometimes points straight down. Then last week "out of the blue" it worked again for a few days. Unfortunately, this only lasted a few days. I never know how fast I am going and try to stay in the flow of traffic. I asked the dealer about this and they did not mention any other problems with this and told me it would cost $500 to repair. This is a real safety issue.
I have a 2004 trailblazer with the same problems with the recall that is going on with gm. The instrument cluster is doing the same exact thing as the tahoe, avalanche, and I forgot what the other the car was. The fuel, water, and battery gauges, the airbag light, a long with the battery light stays on. Went to the dealership to find out why there wasn't a recall and they couldn't give me a answer. I feel that if gm is having the same problems with the other cars and haven't look to see if there is complaints on these, why haven't they added them to the recalls. Paying for the repairs and haven't to wait for gm to send out a recall on a VIN type specific car is ridiculous. If they are having the same exact problem they need to check the other cars. I called the corporate office and they are telling me that I have to wait to see if there is a lot of complaints before they can do anything. If they stand by there quote of customer satisfaction then they are not satisfying the consumers and make them go through a whole ordeal, on finding a solution. Now I have to wait 3 days for a part and fill my gas tank up every other day to make sure I don't run out of gas. Plus, since I can't look at my instruments to tell if my car is going to overheat and make it into a bigger problem. So, since I called the corporate office we will if the people who spend money on there product will make good on customer satisfaction.
In march 2006 at approx, 38k miles our speedometer and tachometer started going crazy and they still do not work. Now the water and oil gauges are going out.
Speedometer doesn't work.
Speedometer is incorrect. It will start off fine but after driving for about 10 min the speedometer needle will start falling to 0 at a slow pace.
The speedometer on both my 2004 chevy trailblazer ext and my 2005 chevy cavalier sedan have been functioning erratically, I.e. Registering 100 MPH in park and then not registering a speed at all.
The speedometer on my 2004 chevy trailblazer is not working correctly. While the vehicle is stopped it still registers 15 - 20 MPH. I have read reports of this problem all over the internet but gm is not issuing a recall or service bulletin that anyone will admit to. Overall this truck has served my family well, but this is my wife's truck (our main vehicle) and I need everything to work properly. We purchased this vehicle because she travels with our children and we need a very dependable vehicle. If this was an isolated problem I could understand the repair at my expense, but report of this problem are all over the internet. Gm should stand behind their product.
Make: chevrolet model: trailblazer 04' ext the speedometer on the vehicle has stopped working. This seems to be a huge problem with "trailblazers" between 03-04. Many complaints, but no action taken by chevy to fix this. I would like for this to be looked into, as this is a huge safety issue. People driving around and not knowing their speed could cause an accident??
Gauges in gauge cluster give false readings speedo in particular reads 120mph when not moving , when vehicle switch off and then back on the reading changes , sometimes goes back to normal happens periodically through out the week; gauges affected tach, speedo, voltage.
