Filed Jun 8, 2018 · Electrical, Lights · 81,000 miles · VA

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. I noticed on the web on cars complaint.com amany people have cmplainted this issue.chevrolet had investigated ths issue aaaaand no resolve. I felt the vehihicle may have a short r a bad alternator or starter. .vehivle was sitting at intersection I noticed it tries to stall on driving also. All records are with car.

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://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.

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

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.

I have owned my 2005 trailblazer ext ls since january 2005. In august of 05 I noticed my gas gauge going haywire.then I noticed my speedometer wasnt working correctly also as soon as my fuel gauge stopped working completely my speedometer has been fine. My fan for heat and sir stopped working shortly after that.I also go through head lights and taillight frequently which have lead to a few tickets. I love my trailblazer but I am disgusted that there hasnt been recalls on these obvious defects!!!! I will not buy another chevy. I feel the company doesnt care weather they have a trust worthy reliable vehicul as long as they are making money!!!!

Lights dimming and flashing alternator not charging, wiring problem, dealer has no answer. I have vehicle just started this at 74000 miles, was fine up until that point. Heater fan works intermittently. Ghost electrical problems with door locks, radio , high beams. Very scary to drive.

Our 2005 chevy trailblazer's low beam headlights have been replaced, the wires were replaced and worked long enough for me to go out at night. The first night I did go out, they stopped working. I was stuck out of town with my little girl. Thank goodness I wasn't driving or in a place where I didn't have cell phone service(which I don't have close to my home). Also, our fuel gauge doesn't work. We've had it repaired and it worked for a short period as well, but doesn't work any longer. Apparently, these two issues are common problems that chevrolet needs to address. A recall would be nice. I have two more payments and I do not want to buy a new vehicle. Nor would I feel comfortable selling this one as it is.

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.
