I have 2005 chevrolet trailblazer 4wd ext ls 4.2 liter. I noticed over past 3 years that I be at drive through for burgers and etc. The car would cut off. I did not think much of it at the time. It has gotten critically worse. It would cut off in middle of the highway, drive throughs and etc. During the past two years I have re the luster and over head dome light flicker. Head lights very dim on driving also I have replaced on this vehicle the fuel throttle and sensor, a crank sensor a cam sensor, a temp sensor 4 power steering pumps new the power steering rack and assembly wheel hubs and bearings, all new coils spark plugs, belt idle pulley power steering pulley change oil every 3,000 miles air filter change battery, updated soft ware, flush fuel system, service the air condition replaced rear shocks, gm relaced pulley on engine 2010 replaced the pvc hose flush radiator and brake system, rotation and alignment done every 5000 miles, replaced headlight low beam bulbs and left tail light assembly and lens, I had it to chevrolet private mechanic garage and nothing is reading wrong also notice the ECM not storing the service engine light stay a microsecond on. This highly dangerous can stal or quit and be run over on highway.

Passenger air bag light not working and coming on when no passage. Check engine light has been on since 2006. Seat belts in 2nd row seating don't lock. Radio broke 2006 replaced after fixed cd player will not play or eject. Air conditioner only blows out hot air after hundreds dollars to fix it. Both head lights blow out at least every 2 months they need replaced. Drivers side break light n tail light keep blowing went to auto store get more bulbs and the tail light caught on fire employees helped me and said they seen the trailblazers do it before due to water building up in it and that that's the reason the bulbs blow. Paid out 300$ in tickets cuz of them blowing n not knowing. The hot and cold air in second row don't blow out at all. A bike parked by me and my back window exploded. Windshield vision is cloudy. Gas gauge, speed ad temp gauge stopped working had replaced now battery gauge broke. Only 1, and 2 worked on heat control and 2 vents worked. Bottom of both sides of car rusted 2 years ago. I had it paid of in 3 years and wish these problems were made available before I did. I've already put thousands of dollars in it and the same thing breaks again and windows in front broke too.my blazer has bee in the garage since january cuz as soon as my husbands gets it out the shop it needs to go right back and we cant afford to fix it nomore I love my blazer and don't want him selling it or trading it in s if you have any advice that would help please tell me. I've been keeping it hoping to get it fixed again but I also have a disabled grandson and custody of a 2 year old that have apts n therapy 4 times a week and need a car but I love it and cant part with it. Please let me know if there a certain way to fix these problems I can do myself so I can keep it..thanks

While driving my 2005 chevytrailblazer it just turned off without warning, as soon as it did the check engine light and reduced engine power light came on(instrument panel and radio were still working). I tried a few times to turn it back on but it failed to restart. 15 minutes later it restarted and I was able to drive to my workplace a few blocks away, by the time I used my vehicle again(about 3hrs later) both engine lights had turned off. We took our vehicle to an auto repair shop to see if they could diagnose the problem, they recommended that we take it to a gm dealership because there were numerous codes showing up on the diagnostic machine. We took it to a local gm dealership in indio, ca (coachella valley buick gmc). They too said that numerous codes were coming up but after 1 1/2 days with our vehicle they stated that the ignition switch needed to be replaced. We took it in to auto repair shop and he performed the repair that gmc stated was needed. Upon picking up the vehicle from the repair shop I drove home, as I was pulling into the garage it turned off, a repeat of the same issue we were having before replacing the ignition switch. Since this was on sat,05-03-2014 we had to wait until the afternoon of mon, 05/05/2014 to take it back to the dealership, we informed them that we had their recommended repair done and that the vehicle continued to turn off. The following day they informed me that they could not replicate the problem and that we could pick up the vehicle. On thurs., 05/08/2014 the vehicle turned off while making a left turn. 20 minutes later it turned back on and he drove it back to the dealership, they then had the vehicle until 05/12/2014; again they stated that they could not replicate the problem. It has continued to repeat this same problem, again without any warning or indication that there is a problem.

Fuel gauge is erratic. Reads empty most of the time even after a fill-up. Gauge needle bounces from empty to full while driving. Faulty sender causes check engine light to stay on constantly. I received a notice from gm explaining that they would pay for half of the repair, but only if my trailblazer was under 120,000 miles. I don't know of too many vehicles on the road that are 7 years old that have less than 120,000 miles.

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.

As you can see from below the complaint, seems I got a call from nikki at gm or chevy and they stated I need to bring vehicle in, pay for the diagnostic and then maybe they can decide on what to do, I believe this issue has gone on for 5 years now and they should be checking to see what the issue is...could be faulty wiring, which can lead to a fire, safety issue, could be a false warning or worse a real warning, as you can see in the link I enclosed to them, many people paying big dollars to not have this issue resolved, how long does this go on, I am hoping you guys can step in for us and hopefully light a fire and get gm and chevy to finally look into this matter..they are good about crying no sales and need the infraction from the gov to stay afloat, seems the big wigs just needed their wallets fattened, because they is no concern or worries about a safety issue, even the gauges are not working, can you please help us out, [xxx] name:[xxx] email address: [xxx] address: [xxx] day phone: ()-- ex evening phone: [xxx]ex comments: I have my check engine light on, can't seem to figure what is the problem on my 2005 trailblazer, went to this site http://www.carcomplaints.com/chevrolet/trailblazer/2005/electrical/check engine light is on.shtml and low and behold, I am not alone ...are you guys going to help us with this problem, at least tell us why this light goes on, please, it can cost thousands to fix but never have it fixed, even my battery gauge has seemed to die, and the gas gauge seems to flex on it's on also, as you can see some people are just leaving chevy behind, how about some help, you guys used to be good, what happened, I believe this needs a recall to fix this issue...[xxx] vehicle concern info: nature of concern: vehicle model: year: 2005 VIN number:[xxx] mileage: 800051 allow phone contact: yes best time for phone contact: pm.

Started with the service air bag message (known issue). Then the fuel gauge acted up and finally went to e and stayed. Now have and occasional surge in the fuel when I have the brake pressed (known issues). Speedometer starting acting up and no longer works (known issue). Oh and the check engine light is now always on. Started intermittently (again, known issue). Was told $500 from dealer when I called to report the service air bag message. Recall should apply to this vehicle, I don't know what the vehicle went through before I purchased it. Cloth seats/leather seats, the service air bag "sensor" is still broke! Don't have the money to fix all the "known" problems.

The federal safety agency action number : dp10001 I am having the same problem with my 2005 chevy trailblazer. Filled the gas tank and now it goes back and forth from empty to full while driving. Also, the check engine light came on.

The fuel gauge is inaccurate - randomly fluctuates from moment to moment from empty/low fuel light on, full, to somewhere inbetween. This has been ongoing since approximately april, 2010. Check engine light is on, and onstar indicates that an electrical problem is present. Vehicle will not pass emissions testing with check engine light on. Safety concern if vehicle runs out of gas - we are forced to drive it now for only a few hundred miles between fill-ups to ensure adequate fuel in tank. We have researched potential repairs, and they will cost approximately $600-$800 to fix.
