At this time the speedometer started misreading and continues through today. Then the fuel gauge stopped reading and after that the oil pressure gauge & amp gauge started misreading. I talked to the local chevrolet dealership and they told me I would have to pay for the repairs.

The dash component went out, leaving all of the gauges broken, including the speedometer and gas gauge. Also, the fuel sensor is broken so in order to have a working gas gauge, both the dash system and the fuel sensor must be fixed. The doors lock automatically and sometimes won't unlock if they were locked when the car was turned off until the car is turned on again. It takes them 2 weeks to fix the problem!! Meanwhile, we have run out of gas, almost causing an accident, and continually have to gauge our speed by the speed of others around us, if we are lucky to be traveling where there are others who hopefully are doing the speed limit. It's going to cost about $1500 to fix it all and have a rental car for the 2 week period it takes them to fix it. It can't be fixed by a non-gm service center because gm has to reprogram the electrical system once it is fixed so it would then have to be towed to a gm dealer anyway and would cost even more. Meanwhile, we and those driving around us are at more risk because of these defects.

My 2005 trailblazer started experiencing false readings on the speedometer around 96,000 miles. At first it was off by 5-10 MPH then it would correct it's self. Next the oil pressure gauge started with false readings both high, then low, neither accurate. Now it is at a point where the speedometer is no longer reading accurate speed and is not showing any signs of ever re-correcting it's self and the oil pressure gauge as well as the temperature gauge both malfunction on a daily basis in one direction or the other. It appears that this is a known issue with chevy trucks in this class yet the trailblazer is the only model in the class to not be addressed with a recall. If a product is faulty by the manufacturers standard it should be addressed and corrected.

Blowers (defrost/defog ~ heat A/C) intermittently work. Dial goes from 1-5 and today if either blower level #2 and #5 is selected, blower will cut off. Last month it was #1 and sometimes #5.

Lowered the driver's power window & it didn't go back up. Opened & closed door & tried button a few more times, then it went up. Unsure of burn smell as I was on highway. Checked again while stationary & window button non functional. Noted that interior dome light did not light when door opened & all power buttons in driver's door (windows, locks, mirrors) rendered non-functional. Also noted that this door does not respond to remote keyfob for lock/unlock, and door by-passes alarm system. Alarm can be set, door opened with key and alarm will only trigger when key is put into ignition, but unarms when ignition cranks. It should also be noted that the driver's door is the only door that has a key lock mechanism. The rest of the vehicle relies on remote or door switches. Approximately one year later I opened the door (as I could not put the window down) and the interior dome light lit, so I tried the power lock button and it worked. Twice. The entire door again went dead/non-responsive. Without window access, the door must be opened on highways with toll booths. The lack of interior light, inability to readily access the door locks, and the alarm by-pass creates a security issue. The inability to adjust the mirrors creates a safety issue, as the window cannot be lowered.the driver's door no longer locks when the vehicle is put into drive. The scariest thing is that the controls simply stopped. Why? A short in the system is a very logical possibility, especially with the random functioning just a year later. I have noted multiple issues on repair sites referencing this problem with 2005 trailblazers, and as of today (6/15/13) saw a recall for a short in the door for 2006/7 trailblazers. If the same issue is occurring with other years, wouldn't it follow that it was a flaw that should be reviewed in all trailblazers of the same body styling?

The controls in the front doors for the windows stopped working. There was a slightly burnt smell when I got in the car that day. Now there is a clicking sound in my drivers door that happens about every 35-45 seconds even when the vehicle is turned off. When this clicking sound occurs while the vehicle is running my engine loses power. This is also killing my battery every night because it is occurring even with the vehicle turned off with no keys in the ignition. I am afraid it is going to start a fire in my door. There is already a recall for the 2006 and 2007 for this exact same issue. 2005 needs to be added to the list before someone gets hurt.

While driving down the highway, the door locks began to operate intermittently, locking and unlocking. The door locks also operate while parked in the garage and the vehicle is off. There is a buzzing sound in the door and the locks have completely drained a rather new battery. A new battery was installed, but the buzzing and the intermittent operation of the door locks continue. I was told there was a recall on some vehicles for this same problem, but gm tells me there was no recall on this particular VIN. During a call to gm, I was told there was a "rather large recall" pending that would be finalized the middle of january. I was advised because of the problem to take my vehicle to a dealer to have it repaired and gm would reimburse my cost "if it was involved in a recall". In a subsequent call to gm, the person I spoke with said there was no pending recall for this VIN at this time. Because of the same problems in other gm trailblazer models, I was advised by the dealer I contacted not to park in the garage because of the possibility of fire due to a possible electrical short in the door module.

Fuel gauge failure. Fuel gauge still reads empty after tank is full. The gauge will register having fuel some of the time, most of the time the low fuel indicator will come on. I have to use the odometer to remember to refuel.

Stepper motors in the instrument panel all went out in three separate gauges. Speedometer, alternator and oil pressure gauges. Items failed and gauges became erratic and then pointed either straight down or pegged left or right. Giving incorrect or no reading.

Gas guage reads empty even though full tank, battery and temp gauge also go up and down, check engine light is on. I know of more than 8 people with similar vehicles of different model years with same issue. Chevy sent a letter saying that they would pay 50% for the repair of the of the instrument cluster if the vehicle had less than 120,00 miles or was 10 years old or less. My vehicle now has 146,000 miles, but the problem started a year ago when there were only approx. 120,000 miles on it. I feel that this is a safety issue being that my wife transports my children in this vehicle and should I neglect to tell her she needs fuel, she runs the risk of being stranded somewhere with my family, or worse on a heavily traveled road where the vehicle could stall with no warning. Thank you for your time.

I own a 2005 trailblazer, the first problem had to do with the gas not pumping. It would cause the pump to cut off. The passenger seat's plastic side broke off and now the driver's seat is broke. The driver's lumbar selector quit working.the speedometer has stopped working. I use my GPS.then the fuel gauge quit working, the "dummy light" stays on all the time. Cd is hung up in the radio. The front fan for AC/heating quit working.the other fans work and the AC cools.evidently there are alot of complains with this certain make/model gm should fix the problems. If they don't fix my problems my nest car will certainly not be an american made one because I haven't seen alot of pride when we have to beg to get our cars fixed when shoddy parts are used on our cars.

This is in addition to complaint 10410347. After purchasing 2005 chevy. Trailblazer (joyce buick, mansfield, ohio) noticed instrument cluster gauges fluctuating and making strange noise. My mechanic advise take to dealer for faulty system, since was still under warranty (3 mo. Warranty). They replaced the instrument cluster cable, still not operating properly, discovered after reading owners manual that gas gauge should always register at gas level, not return to empty when turning off ignition. Now the gas gauge is not function properly as reported in previous complaint. At purchase noticed AC not cooling, joyce buick added coolant and supposedly performed dye test prior to taking possession, reported no leak in sept. 2010. By april/may 2011 AC not working again. Found leak and replaced hose that runs to back of vehicle, (pre-existing condition.) I feel that this vehicle was not properly serviced prior to re-sale. Some conditions covered under 3 mo. Warranty or pre-existing condition and now more issues continue to arise after warranty has expired, ie gas gauge not properly registering fuel level and the instrument cluster gauges still fluctuating. Researched and understand could be some motor relating to instrument cluster.

My 2005 chevrolet trailblazer started at 60,000 miles having my speedometer going crazy and it finally stuck at 120 and only moved occasionally moved I tried to go with the flow of traffic, but ended up getting a ticket...the first in my 50 years of driving. I went to get it fixed, but found out even though it was a defect in the electrical harness, chevrolet was only fixing it in certain of their expensive models. It was going to cost me over $500, which I cannot afford. I use my GPS to watch my mileage. Now the gas gauge stopped working, the cd player, and the other gauges are in question...plus my lights blink off at night. I am a senior and cannot afford to get another car, or even fix this problem. I have found many complaints on the trailblazer for the same problem. Chevrolet should have to make this right. My car has a little over 80,000 miles and I want to keep it the rest of my life. Please help.

Speedometer keeps getting stuck. Chevy has been told about it. But they want me to pay another 500 to fix it. And this is the second time. They have had recalls on the 2003 and 2004 for the same thing. But will not admit the 2005 .

I have a 2005 chevrolet trailblazer ext. Couple months ago the speedometer started acting up, I will be driving and it will stop reading my speed and going down to 0, it will get back to normal after I turn off the car and turn it back on, did that couple times, not very often, then started getting stuck on whatever speed I was going, and didn't matter if was slowing down or going faster, will stay at that speed on the speedometer, couple days ago started to go nuts, now when I am stopped reads I am at 20 or 30 MPH, and when I am going 30 or 40 starts going up and down, marking 100 MPH when I am actually going just 40 MPH, I have read several complaints about this problem with this same vehicle, a recall was issued for older models, but nothing for the 2005, I don't have the money to fix it right now, and I have to use my GPS unit to know how fast I am going, and avoid getting pull over or cause an accident, but I am not the only one with this problem, I will like to have chevrolet take ownership of the problem, it is a safety issue, and is clearly a chevy issue not a consumer one, we paid for a product that supposed to work properly and it is not.

Speedometer quit working, first 70mph then 90 then 120 , it started bouncing around all over the place. Now it has quit working all together. I believe this is a major safty issue. I have checked into it and thousands of people are experiencing the same issues. This is my wife daily driver and she transports my kids in this vehicle. Chevy needs to man up and address this issue.

2005 chevy trailblazer actually my problem started about 2yrs ago when my gas gauge went out. Then year later I was sitting in traffic and once I got back up to speed my speedometer went out and quit workin. It would jump around and then sometimes appear to be reading correctly then jump to zero or way over past 90 which of course I was not going that fast. Now my oil pressure gauge and temperature gauge are going out as well. After checking for recalls I see now there have been alot of complaints with this issue in the same year vehicle but no recalls. If this many vehicles are having similar issues why isn't chevy making it right? I know mechanical things happen after owning a vehicle but not the same thing to this many vehicles.

Purchased the 2005 trailblazer with 49,000 miles. At 50,000 miles the speedometer stopped working properly. When I slowed down from going 70 miles per hour, the needle stayed on 70 and when I accelerated it would act as though 70 was the new 0. Now the speedometer points down past the 120 MPH mark and will not budge. Gm told me that it not under warranty and it will cost over $500 to fix.

Our 2005 chevy trailblazer has a non working fuel gauge and speedometer. We have 4 children. 2 of which live out of state and we drive back and forth several times a month from sc to tn to pick them up. When the fuel gauge went out we were annoyed but we just top the gas tank off often, but the speedometer that just started sticking we have no idea how to handle. We don't have the money to get it fixed but we travel so much for such long distances that it is extremely dangerous. When researching online I see that this is a very common problem yet chevy has not issued a recall. If chevy does not issue a recall for these we will not ever trust chevy products again. The safety of american families obviously does not matter to them. Only our bail out money.

I own a 2005 trailblazer ext and the speedometer does not work. It is a chronic problem according to research that I have conducted. It is a safety issue as well. Gm needs to take responsibility and recall the instrument cluster. The speedometer fails everytime that I drive it. The dealership stated that the cluster is going to run about $400, which does not include labor.
