I bought the Trailblazer everything was great couple of months later the ignition switch went out after that was fixed I noticed the tachometer wasn't working..then the speedometer jumped up to 30 mph while I was sitting still so I brought in as it was under warranty and of course the problem went away but they said to me that they had problems with the pick-ups but not the trailblazers. Then everything was normal for a while until warranty was gone and every gauge except the temp quit working. I called the local news Call 3 for action and I may have some results..I should know something this week so I will keep you informed

Well, I just bought this piece of junk, and I feel like I was suckered and pushed into this deal. When I drove it off the lot, the CD player did not work, but they replaced that. Maybe two weeks, after I got the car, the engine light came on, and now will not go off. then the oil pressure gauge started messing up, and it stays buried above 80, and does not come down. Now to beat it all, my speedometer is stuck on 60, and will not come down. I think Cheverolet makes crap for cars, this car does not even have 100,000 miles and it should not be doing this. If cheverolet can not make better cars, they should close their doors. I am a mother of three boys, I am on disability, and I do not have the money to get this fixed, and they said I cannot trade in for at least another year, but it don't look like this is going to last that long, and it is the only means of transportation I have. I am pissed, and would like to know if anyone has any suggestions on how I can deal with this problem. My thought is is to wrap the damn thing around a tree.

Just bought this truck used last month. Drove it for 2 days and started having problems. I was on the interstate doing 70 with the cruise control on and suddenly the cruise went off and the service engine soon light came on. It was chugging and the tach and speedo weren't working right. I took it back to the dealer and they fixed the engine problem (spark plugs and a clock spring) and the gauges were back to normal. Drove it over the weekend on the interstate again, cruising at 70 and again, the gauges stopped working properly. I've been researching this problem and have noticed a ton of complaints about this. My piece of crap pontiac grand am had 80,000 more miles and never had problems like this. I've found used replacement parts for less than $200. I even found a site that you can ship the entire gauge cluster to and they will fix it for $150. I think GM should foot the bill and give me a loaner car while they do it.

Once this car hit 40,000 miles it has been one thing after the other. Rotors only last 20,000 miles before rusting and warping. this is a common problem for all GM. I am on set 3, Tranny lines rusted through at 42,000 miles. Gas tank filler leak at 46,000 was replaced under extended warranty. shifter cable stretched out and required replacing under extended warranty (thank god for the extended warranty but it ran out in August. Heater rheostat burned out at 48,000 milres, another common problem with GM trucks/SUV. Now the Tach is working erratically and GM wants $500 to replace the dash cluster as you cannot service the gauges separately.

this is an extra clean low mileage car I bought new and the dealer tells me I have problems because I do not drive it enough? What am I supposed to do--move farther away from work? I have owned Chevy's and GM since 1965 but they have degraded to junk Time to switch allegiance..

Bought a used 2004 Trailblazer at 6PM and at 10PM, on the way home, I already started having my first problem with it! The second time behind the wheel, the speedometer stopped working and the "Service Engine" light illuminated simultaneously. I haven't had the vehicle as of 6 hours of this writing and I'm already having to search the internet about problems with it. Not good. Granted, I did buy it with high miles on it (150k) however, its disappointing to know that this is a common problem with this year range of this brand/model. Either two things are forthcoming: 1. A future speeding ticket because I don;t know how fast I'm going -OR- 2. I shell out $500+ to have it repaired. NOT looking forward to either one of those options knowing that I JUST got the damn thing.

Just another one of us with the gauges acting up. I have only experienced the fuel gauge and the speedometer thus far. Fuel gauge I can handle by resetting the trip odometer every fill up but the speedo is a real pain. Today it said I was going over 120mph on the way to work, felt like 50-55. I am calling gm to see if they'll throw me a bone on the repair. I spoke to a few mechanic friends and the say that replacing the cluster will solve the problem but like most of us I dont have 500-600 bucks laying around that I'd want to spend on there screw up

I had a faulty speedometer. It was possessed, giving whatever speed it wanted. i aveaged my speed by the tachometer. However after getting a speeding ticket i took it to the dealer and they said it was covered under service recalls but my milage was over the limit and i would have to pay the labor of $200.00 ok i paid for labor but upon receiving the vehicle back the radio doesn't work. they now tell me that the radio isn't covered under warranty. i then took the vehicle to a radio insaller and they told me that it was the onstar interface and that it would cost me $200.00 to fix the problem.

i decided after negative feedback from the dealership that i would take them to small claims court for the out-of-packet expense. they are now backing down from the repair and telling me that its not covered and i would have to pay them for the speedometer assembly over $800.00 including labor. ever wonder why everyone buys japanese. chevrolet is screwing with the little guy, they should never have gotten any bailout money

OMG!!! Ok, I'm engaged, but he's gone alot so I'm pretty much on my own...with this stupid axx car!!! I'm on my way to work...55mph, right? Hell no! It says I'm doing 125!!! WTF??? There is no way in hell I was going this fast! I like my job, but I didn't want to get there with the quickness!!! So, I slow down, because now I don't know how fast I'm going! I've been late 3 times this week! Then my radio goes out! I was rockin' to STP in stereo...then I swear I was listening to a transistor radio on crack! So, now it takes me forever to get to work with nothing to listen to, but my thoughts on how much I hate this stupid car!!! Chevy dealer guys said it'll cost over $600 to BUY the part! WTF??? How much to fix the friggen thing then?!?!? It's because I'm a girl, huh? Oh & half the dash lights & the cigarette lighter thingy don't work either!!! & my gas-o-meter is possessed!!! It CHOOSES just how much gas it wants me to have!!! I'm gonna chunk this damn car off a cliff...if this town had a cliff...lol

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.

The odometer just stays stuck on whatever mileage the car was at prior to stopping. The odometer has stopped below the zero and has stayed there. The odometer has stopped on the 120 mark and has stayed stuck. the odometer has stopped on the center of the dash below the 120 near the digital mileage window. It is very frustrating because when you are on the highway you do not know what mileage you are going at and the last thing you want is a State Trooper to stop you because you are speeding and your odometer is registering 15 miles per hour.
