 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 occuring 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. *tr

 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.

 Gas guage reads empty even though full tank, battery and temp guage also go up and down, check engine light is on. i know of more than 8 people with similiar 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

 My 2005 chevolet trailblazer started at 60,000 miles having my speedometer going crazy and it finally stuck at 120 and only moved occassionally 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, chevolet 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 compliants on the trailblazer for the same problem. chevolet 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.

 I have encountered a problem with the speedometer not working properly or not working at all in some cases, sometimes get stuck at a certain speed

 2005 chevy trailblazer actually my problem started about 2yrs ago when my gas gauge went out. then year later i was sitting in traffice 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 haing 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 49000 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.

 My 2005 chevy trailblazer is completely going crazy it seems everything electrical is going wrong with it. i am afraid to let my wife or my kids drive in it because i never know whats going to go wrong while driving. my whole gas system is gone from fuel level indicator to the gauge. my entire dashboard is not working. lights are going out. what is crazy about this is that i am one of thousands that this is happening to. chevy needs to fix this problem before someone does get killed. waiting for fatalities before making chevy fixes there awfully made vehicles is unacceptable. i understand the situation our economy is in but these thousands of trailblazer owners that are having these problems shouldn't be paying thousands of dollars to be getting there entire electrical problem fixed. i do not know one owner of a 2006 trailblazer that does not have this same problem. it is unethical and chevy instead of stepping up and fixing there problem are making there loyal customers spend thousands of dollars fixing there mistake. it is truly sad that i do not trust taking my vehicle with my family in it because of being afraid my vehicle will fail to drive or malfunction. please hold chevy accountable and make them fix our poorly mad and unsafe vehicles so we can feel safe driving our family around again.

 I have an 05 chevrolet trailblazer ext 4.2l with 90000 miles and last march the fuel guage quit working but not before we ran out of fuel 2 times not knowing that the guage was giving a false reading.the occurence happened on the freeway and once on a busy street. very scary when you have three innocent little girls under the age of 3 that ride in the vehicle. from doing my research i see this a very common problem and a dangerous one at that because when the truck stops running you lose power steering and power breaking

 Speedometer quit working on my 2005 chevy trailblazer as i was on the highway (i-75). at first it was reading 20 to 55 miles per hour faster than i was actially going and an hour later it quit all together. at this time it does not shoe a reading at all. very hard to determine speed without a speedometer in heavy traffic and creates a hazard to other drivers and myself.

 The speedometer stopped working one random hot day. there were no resulting injuries, incidences or crashes as a result. my trailblazer has yet to have a reliable day where my speedometer works continuously.

 I have a 2005 chevrolet trailblazer ls ext and the speedometer, fuel, and battery gauges do not work properly. there is a dimming of the lights while driving and people sometimes think i am flashing my lights at them. according to http://forums.trailvoy.com/showthread.php?t=18419&highlight=gas+guage&page=2 this has been a known problem for several years and no one has done anything about it. there are several other forums out there that say the same thing,this is a major safety hazard and could cause major problems including accidents, speeding tickets, running out of gas...the problems are endless i guess. something needs to be done. why has there not been a recall on this with so many complaints? are you waiting for something serious to happen?

 I own a 2005 chevy trailblazer and the speedometer and gas gauge have both stopped working. i started having problems august 2009 when i filled up the gas tank i left the gas station and it said i was on empty. i turned back around and went back to the same gas station and the manager tried to fill it up and it showed i had a full tank at the pump. it started to work again but then it would fluctuate back and forth. now it's just not working at all for me. the other problem i have is that the speedometer went haywire. i would show i would be going 10 mph and actually was going 50 mph. then when i would stop it showed while in park 70 mph. i would have to then turn off and on my car to zero it out. the speedometer is stuck past the 140 mph mark and has moved. this is very dangerous because i have 5 kids and this is the vechicle i use to transport us. what if i get a ticket for going to fast or to slow and what if i run out of gas on the highway. this is very scary and unsafe. i was told by a friend to see about any recalls and found none. i then contacted gm and they told me i have to take it a gm dealer for a diagnostic but there is no guarantee they would cover the cost. they said because of the mileage and year that it's from normal wear and tear i have never had a problem with any vechile like this before. how convenient after the warranty goes out i have this problem. after looking online for recalls i found several other similiar cases of the same year, make and model with less mileage having the same issues. i did ask the gm representive for somewhere else to file a complaint and they stated that they were it. i'm very unsatisfied with gm and the policies and i don't feel as if they are really conserned with these issues.

 I have a 2005 chevy trailblazer and it has many problems. but the most dangerous, at this point, is the speedometer stops working. sometimes, it won't get off of zero. other times, it shows that i am going over 120 mph, when in fact, i am going with flow of traffic. at other times, it shows either 15 to 20 miles above or below the speed i am actually driving. there is no common denominator as to when or if the problem starts or stops. it is very, very random. the cost to fix will be over $450.00. there are many other trailblazer owners that are having this same problem. the speedometer problem could be very, very dangerous as the driver does not know how fast, or slow, they are actually driving.

 I own a 2005 chevy trailblazer in dec. 2009 i filled the car with gas and the fuel gauge immediately registered empty the fuel sensor has failed it will cost $558.00 to repair. in february the speedometer registered 120 mph while sitting still for a stop sign now the speedometer does not work. i contacted gen motors in detroit, michigan and was asked to have diagnostic done at ed bozart chevorlet. by a representative in consumer complaints they contacted district representative for chevy and they both said that there is nothing they can do to help us. the total cost to fix our car is $1,258.00. we were told to fix the car for safety reasons and if they decided to recall the trailblazer we might be reimbursed. there are several complaints in the computer concerning the same problems with this car. *tr

 Speedometer gauge is malfunctioning. when traveling 65 mph, the speedometer reads that i am going faster than 120 mph. when i shut the engine off the needle falls to about 70 mph. in town, the speedometer shows around 90 mph. there is no way to tell how fast i am going. *tw

 2005 tb ext, summer of last year the computer had to be replaced, about 6 months ago the speedometer quit working, the check engine light stays on, the gas gauge wont work, the heater wont work on 5 and there is no heat in the front vents,the oil light does not work,, i have had it aligned but the back tires keep going bald,,it looses power so bad,,,,i went out this morning and the headlights wont go off and now my battery is dead...what else is left to go wrong??? i have 5 small kids and someone is going to get hurt because this vehicle is defective and no one wants to take responsibility to fix it.. so now when is someone going to fix this problem ?if i spend $24,000 on this used vehicle with only 30,000 miles on it when i bought it feb 2008 it could at least run decent..you would think it would be cheaper for chevrolet to fix this vehicle than to have a lawsuit. *tr

 My husband was driving on the interstate at about 65-70 mph. all of a sudden it dropped down to 40 and we immediately pulled over and turned off the ignition. the needle was still reading 40. we were three hours from home and had no choice but to continue driving. once we got within an hour from our house it started working correctly. three days ago i was driving by myself and it happened again. the needle is stuck on 60 mph and my car is parked in the driveway. please address this issue asap i don't think i should be driving around in a vehicle that isn't operating correctly just because i didn't choose to buy an escalade, tahoe, or suburban. vehicles that have the same problem and were issued a recall. *tr

 2 gauges in ipc have malfunctioned: the speedometer and the fuel gauge. the speedometer needle begins to stick at 60 mph mark and does not reset back to zero after turning the ignition off. in fact, while on the freeway, the speedometer will often go past 120 mph mark. the fuel gauge needle sticks at the empty mark. common sense dictates that driving a vehicle without any clue as to how fast or how much fuel you have is hazardous. my research has determined that gm has recalled the ipc for other 2003, 2004 & 2005 cadillac, chevrolet and gmc models but not the 2005 chevy trailblazer. *tr

 My 2005 chevy trailblazer lt speedometer has gone haywire. it will work and all of a sudden it drops to below zero. it will occasionally hover between 5-10 mph and then drop again. since it fails to show what your true speed is, it is a very hazardous condition. *tr

 Once my warranty ran out, the gas gauge quit working and a couple weeks after that the speedometer quit working. i have researched online and found many people who are having the same problems with the same make and model car. *tr the repairs are very costly. the repair should be fixed through a vehicle recall since so many others with the same vehicle are having the identical problem.

 Vehicle instrument failure during driving. the speedometer will jump and read between 15-80 miles per hour off, usually high but has read low. this leads to either excess or slow speed, both conditions are dangerous in freeway and winter driving conditions. there is a recall for this problem on every other chevy vehicle from 2003 to 2005 on a truck base but not this model. there is also failures in both voltage and oil pressure gauges, each have led to making emergency stops on the freeway to check for problems. problem can be corrected by turning car on and off multiple times (10-20) to reset gauges. *tr

 I purchased a 2005 chevy trailblazer less than a year ago. since that time the vehicle has been in the service center four different times. each time the vehicle has failed to start. the dealer states that the rear hatch module continues to short out. this module causes the entire vehicle to short out. i have expressed my concerns with the safety of this vehicle with the dealer and have not gotten anywhere. i an a single mother of a two year old. i am only interested in the safety of my child. jack schmitt chevrolet of o'fallon illinois will not stand behind the vehicle that they sold or admit that there is a problem. the last time i brought my vehicle in for this problem they told me that it was the ignition. when i came to pick up the vehicle after they had fixed it, the vehicle would not start. they admitted that it was in fact the rear hatch module again and that they had made an educated guess the first time in order to save time. i would like someone to hold this dealership responsible for the defect in this car and to stop giving consumers the run around. *jb
ELECTRICAL SYSTEM - IGNITION

 I parked the 2005 trailblazer in the garage after a short trip to pick up a neighbors child. two hours later when i went to start my car to take the child home, my key would not turn. steering wheel was not locked ( it could be turned and turn the wheels) trans was locked. i read on online forums that others have had issues like this, one guy said that he was able to pull back on his shifter and turn the key at the same time. this did not work for me as the trans shifter was locked. result, tow, and replace switch. *tr
