Problems with 2004 Chevrolet TrailBlazer EQUIPMENT

Service engine soon light was on after completing a diagnostic test at a local dealer they said the malfunction was the secondary air injection(air pump) code p0410. they said the reason these go out is because of an engineering defect and the way they routed the hoses instead of air flowing through it causes water to accumulate therefore making the motor in the air pump to go bad. so while changing out this bad air pump there was so much water that had accumulated it actually caused the light to blow which could have caused the mechanic to be electrocuted! *tr

All of my gauges on my dashboard completely turn off and then randomly turn back on. it is very dangerous to drive around with no speedometer, gas gauge, olil, battery, tachometer or odometer on. then it all of a sudden will turn on. it needs to be recalled. i took it to a repair shop and they said it would cost around $500 if not more to have them take apart my dash and look and then possibly send it out to seeif it can be fi.xed there are numerous people i have found online with this same problem with the same vehicle.

Headlights continually burn out. replace every month! just replaced on 2 days ago and already out again! speedometer does not work. *tr

The problems that are happening to my 2004 chevy trailblazer : i am having a whining noise in the front end of the vehicle and when i try to engage into 4wd the sound worsens and there is a vibration in the front as well the whining almost resembles a low siren sound. i am also having a major malfunction with my speedometer since the weather has gotten colder??? i could only be moving 10mph and it will register to 120 or even surpass it and then get stuck, the only way to unstick it is to shut the car off and keep restarting it until it resets itself but now it is stuck and wont reset, i went online to see if there were any recalls and i all i found out was there were tons of people having the same issues with their trailblazers as i am having. these problems are occurring at all different times during the life of the car some people have them happen around 30,000 miles or some 50 thousand and myself the speedometer is happening around 72,000 miles. the speedometer seemed to start to act up once the weather was colder. its a shame they will fix the larger suv's due to a lawsuit but since this is a smaller suv it's not covered. we have tried to replace the wheel bearings in the truck for the front end noise to only find the noise did not disappear after reading many of other complaints from others it seems this could be the transfer case on the truck. i am not going to keep replacing part after part to only find out its the drive train and something should be done about this. *tr

Failure of the gauge cluster on a 2004 chevy trailblazer currently with 59,300 miles. about june 2009 the tach continually read incorrectly. dealer tried to mislead me to bring it in for a diagnosis at a cost of approx. $100 i told them its broke why should i pay for a diagnosis. i had read about the problem on -line at edmunds,com.,my suv had 41,000 to 42,000 miles on it. in july 2010 my gas gauge started to occasionally malfunction, now jan. 2011 it is incorrect. in nov. 2010 my charging gauge started malfunctioning. i also have since read online of the same problem on other similar year gm trucks ans suv and they have recalls on them. its just a matter of time for the speedometer gauge to read incorrectly. please help, these malfunctions are not safe. *ln

Tl*the contact owns a 2004 chevrolet trailblazer. the contact stated that the speedometer stopped working and registers 65 mph while the vehicle is parked. the failure prevents him from knowing how fast he is traveling. the dealer has not been notified. when the contact bought the vehicle, the spare tire wrench under the rear bumper was stripped so that it could not be lowered. he had a mechanic examine the spare tire wrench and was advised to take the vehicle to the dealer. the current mileage was 66,000 and failure mileage was 62,000.

All within the last few months i have had to replace the complete drivers side low beam headlight and electrical pigtail because it caused an electrical short that burnt the wires. a few weeks later driver's side rear stop light quit working, i had to replace the bulb, next, the blower motor won't work on 5...and it won't transfer from defrost to vents...so, i am currently replacing the blower motor resistor and the red wire is fried because it appears not to have been "pushed" all the way in from the factory, (i have taken a picture of it)and now i have to "replace" the entire wiring harness...i'm really starting to hate chevy...especially when i browsed through all the complaints... is there ever any resolve? i think most of the issues i /we have are all safety issues...would you handle things differently on your end if someone you know and love was in this type situation where they were concerned for their safety as well as the public's safety!!!! *tr

I have 2004 trailblazer and cluster is bad this need to be recall . i need to report a problem a can't solve with gm complaint number from gm is 71-683-983-288 and vin number it will cost around 600 to replaced. *tr

My seat belt reminder light does not come on when starting the vehicle nor does it chime when you don't have your seat belt on like the owners manual says it suppose to do. *tr

In april 2007, the '04 trailblazer's transmission failed. at the time the vehicle had less than 50,000 miles. i drive the car very well - mostly highway miles as i commute for work - and the vehicle had never been used to tow. the transmission was repaired at a chevrolet dealer, and less than 2 months later, the transmission failed again. i am very unsatisfied with the quality of this vehicle.*ak

2004 chevrolet trailblazer. the vehicle's a/c air output works fine, but when you switch it to heat, the output for this is diminished considerably. the vehicle heats up fine, but even when the airflow is entirely at the dash (none directed to the floorboard) the output of air for the heat is very low; so low it can't even be felt unless the hand is placed directly in front of the vent no matter how high the setting is. veh has been taken back to the dealer (under warranty), and was told no diagnostic problem was detected; everything is working properly. compared my vehicle to others of similar make/model/year, and dealer says all work the same. this is not true because last year, i could not stand the heat on setting of more than two because the output was very good. now, it can be put at a higher setting, but with little heat output. i communicated with an internet service technician who says it is the air flow door that is not sealing properly. the internet service technician also said it is difficult/tedious to fix this problem. i think the dealer just doesn't want to mess with it as it is under warranty. *nm

I have had my trail blazer for 1 yr and 1 month. in that time i have had to replace front and back pads and rotors, ball joints, catalytic (sp) converter, and now they just told me i have to replace the head gasket on the manifold. what the hell is going on with this vehicle. i no longer feel safe driving it. the other day the radio just stopped playing and then the service 4 wheel drive light came on. *nm

Horn has intermittent issues of working - we have taken to the dealership on several occasions and then it works. they do not want to take apart the steering wheel assembly to research the problem regardless of the number of times we have had the vehicle to the dealership. now that the warranty is expiring, i am sure the problem will be researched since it will be at our cost. the horn only seems to work when the car is first started and the steering wheel is moved shapely. since it is under the air bag, the dealership doesn't want to deal with it. *tr

2004 chevy trailblazer electrical system has serious problems. in the rather short time i have owned it, it has been in the dealer repair 7 times for the same group of problems. the outside mirrors keep pointing to the sky randomly causing brief confusion when they are needed for safety. the pre-set memory keeps clearing itself. the headlights and dash lights often go very dim and flicker causing distraction to the other drivers and fear in the driver operating this vehicle. the driver's side heated seat stopped working. the passenger side door window controls randomly stop working. turning off the vehicle and restarting it is the only way to correct it. all of these items have been looked at by the dealer but no solution has been found. several computer reprogramming and parts have been replaced but the problems still remain. the dealer does not acknowledge that information posted on the internet by other owners of this vehicle is valid. that is bull~h@t !they seem reluctant to continue troubleshooting it. my greatest fear is that it ends up burning to the ground like many other owners have reported. something has to be a common problem for all of these electrical issues with these vehicles. *nm

Turn signals inoperatable at times. brought truck to the dealer they replace a faulty hazard flasher.

The problem is that my 2004 chevrolet trail blazer spits up fuel back out of the fuel tank after filling up the tank. i am not trying to top off. everytime i fill up, fuel spits back out from the tank after i remove the fuel pump. i have taken my car to the dealer twice now, they are on their third attempt to fix the problem. it happened several times before i took my car in to the dealer. i thought maybe it was the gas station i was using. so i tried several different pumps in different cities and the same thing happened. that's when i decided to take the car in for service.*ak

Major electrical problems inside the vehicle. i have owned it less than a year.the vehicle has been in the shop twice in the past two weeks. exiting the freeway the i had a complete power failure. the vehicle completely stopped and locked up and there was a semi truck behind me! my vehicle was moving and in "drive" when this happened. i had two of my toddlers in the car with me! the vehicle was taken into a local dealer and unfortunately they could not find anything wrong with it. apparently, when the vehicle is restarted it erases the codes in the engine as to what caused the problem. well, it happened to me again this evening. same problem. this will be my 5th time of bringing this vehicle in for electrical problems in less than a year. i only have 9400 miles on the vehicle and bought it brand new. i do not feel safe driving this vehicle with my 5 children as passengers. is there a way gm can get me a better running vehicle? i paid a lot for this vehicle and am very unsatisfied with it's performace. there always seems to be something wrong with it. the connell chevrolet service here in killeen has been very helpful. i feel sorry for them because they did not sell me this vehicle but they are the ones nice enough to try and fix the multiple problems.*ak
