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.

Driving 6 people to pittsburgh international airport at 3 am 8/5/17 on the parkway to catch a flight for a vacation when noticed low beam headlights were not working. Do not know how long I was driving before this was noticed. Low beams worked the evening of 8/12/17 @ 10 pm after returning to pittsburgh airport and driving home. Low beams did not work again on the evening of 8/24/17 when driving home from a baseball game. Repairs were completed 9/1/17 by nick chevrolet in tarentum, pa. I had asked before and after the repairs whether this would be covered under recall but was told no because my VIN number was not a part of the recall for this issue. They made it seem like this was a separate issue from the known low beam issue recall of other chevy models. I also called the gm customer service line to see if I could get reimbursed for this issue but was told the same thing; that my VIN number was not a part of the recall and it is based on what factory the car was made at? The part number used was 15016745 which upon looking on the internet is a replacement part for the other vehicles covered under the recall. I do not understand how the same issue can be part of a recall for some years and models and not others if the problem and part are the same??

There is already a recall out for the 2006 model year, but I know that mine is part of it. I have a 2005 trailblazer and the headlights keep intermittently going out as I am driving down the road. This problem as happened to me before in the past and I was able to finally remedy the issue by replacing the relay. The problem has now returned and I have even been pulled over multiple times for it. After doing a quick google search today I discovered that there are tons!!!!! Of people with the same issue going back as far as 2002. Http://www.topix.com/forum/autos/chevrolet-trailblazer/t32jtl93i9fkauf4n http://forums.trailvoy.com/showthread.php?t=47492 http://chevroletforum.com/forum/trailblazer-27/2003-trailblazer-headlights-2588/ I also ran across that gm has issued a recall for headlights, but it only covers years 2006-2008. Http://fortune.com/2014/12/01/gm-recalls-316000-vehicles-because-of-malfunctioning-headlights/ clearly!!!! This problem is not limited to those years and there are a lot of people suffering from the same issue of not being able to see at night.. What do I need to do so that I can get this problem taken care of? Please respond quickly as winter is rapidly approaching and this is a daily driver for me. I go to work early in the morning when it is dark and by the time I come home again it is already getting dark. It would be nice to actually be able to see as I am going down the road and even to have others be able to see me coming as well.

All of a sudden headlights stopped working. I have changed the bulbs, fuses and relay. Had this problems checked out several times, no one can find a solution to why they don't work. I was on the highway coming home when they just stopped working, I had to put my high beams on to be able to get home safely.

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?

2005 trailblazer fuel sensor unit faulty. Fuel gauge does not correctly show the correct amount of fuel. It shows empty although the fuel has been filled. On at least one occasion my spouse was left stranded due to this failure.

I have had the following problems with my 2005 chevy trailblazer ext ls: 2008: fuel sensor failure, running board fell off 2009: head and tail lights going out frequently, windows would get stuck- could not go up or down- all dash lights flashing, car stalling out- needed circuit board replaced. Anti-theft non-functioning. 2010:windshield wipers will not shut off(replaced display board), idle pulley needs to be replaced , 4x4 running rough and making a sound,speedometer non-functioning, radio stopped working,glove box lock broke, heat/AC stopped working first on blowers 4& 5 then stopped completely I have not been able to afford to fix all these repairs, as it exceeds $2,000. Car is over warranty and was brought used from a former gm dealer at under 50k. I contacted gm in november 2010 and they stated that they my vehicle was out of warranty and they could not assist me. Gm initiated contact in december of 2010 and told me to get a full diagnosis of the problems and stated that it was ok to go to the former gm dealer. I paid over $100 for this diagnosis and they stated that my vehicle was out of warranty and they cannot provide any assistance whatsoever.
