Our vehicle died at a turn signal light in a dangerous intersection. No warning from the vehicle as it was running normal. It would turn over but no start. Police force a tow out of the busy intersection right away. It starts up at the mechanics. They tested fuel filter and other stuff. We get on the highway in traffic and get 6 miles out and no warning we die and had to push the car to the shoulder on in dangerous conditions. Sit for 2 hours and it fires up. So we found shade and waited for cool down. 2 hours away from home and it took us 9 hours to get home. We drove it to the store and when we were done shopping it fired up. Went around the corner to other store and shopped 2 hours and came out and it would turn and no start. Tried starting every 30 minutes to hour from 9:30pm to 1:40am and then it fired right up then drove 30 minutes to home. After researching and finding quite a few with same year make and model having the same issue we found that it is the pwr/trn relay plug in area in the fuse relay center. When we broke the plastic off the relay and wrapped a rubber band around it so it's constant contact and plug it in, it will fire up every time. I can drive it all day like that with no issues. I have to turn the key from running to accessory mode then remove the rubber band and then power off the car. Don't want to fry com. The relays are good and problem is the fuse relay center. Chevrolet said themselves that this model is notorious for fuse relay center problems and usually require replacement. It's a known defect. There are two pictures attached from one of the other people with same vehicle same problem and in order to make his fuse relay center work properly he had to wire/reroute his pwr/trn relay as seen in the picture. This needs to be investigated as this is a well known issue with chevrolet and the trailblazer.

Drove to an appointment, when came out vehicle would not start. Called for tow. After approx. 30 mins. And before tow arrived, vehicle started. Was able to drive home and made appointment for service. Next day while driving to shop for service engine died while vehicle was moving. Managed to get off road and vehicle would not start. After a while it started and was able to get it to shop. Ignition switch replaced. Second incident occurred 6/1/2014. Had to have towed to shop. A second ignition switch replacement. Contacted chevrolet to inquire why 2005 trailblazer not included in ignition switch recalls and seek possible reimbursement of service costs for recurring problem and was told to contact the federal safety agency and report.

My car was starting fine before this. I left work went out to my car tried to start it and it would not do anything other than electrical noises even after I took key out. Got a jump (it was quick) the gauge was moving slightly. Got to where I needed to be and turned the car off and immediately it would not start. Jumped it again got home and the key got stuck in ignition and the lights flashed inside and out of the vehicle all night!

Vehicle's headlamps will power surge, dim while driving periodically. Fuel sensor showed constant empty until repaired by the recall. Vehicle will occasionally surge forward revving on it's own at random times. The blower resistor pack has burnt up twice, the blower motor has been replaced as well as the melted wires.now the vehicle will not start. The power windows, locks, radio, dome lights, dash lights are inoperative and the vehicle will not attempt to turn over. Seems like this vehicle has had a lot of electrical issues.

Vehicle would not start. Had it towed to mechanic shop. Battery was completely dead, though the battery was only 1 year old and was a very expensive AC delco 6 yr battery. Mechanic changed the alternator and the battery and everything tested the same. Put old battery and alternator back in, as battery he charged was holding the charge ok. Could not locate source of problem. The next day, the dash lights were not working, nor the interior lights. As I drove along the highway, the dashlights blinked and then stayed on. Ceiling light works intermittently. The alternator shows that it is charging very hard. According to other incidents reported on the internet, there is an electrical problem in the 2005 trailblazer that may or may not be associated with the passlock anti-theft system, but in any case, shows slow leak of electrical current that slowly drains the battery 24/7, until the battery is dead. Why is no recall issued making general motors responsible to find and fix this problem without cost to the owners of 2005 trailblazers. I spent $130.00 at the mechanic shop and they could not find what the problem is, much less fix it. My vehicle is parked in a garage most of the time, and there is no reason for this malfunction other than faulty gm part somewhere. Our local chevy dealer told me they think the problem is related to the passlock anti-theft system but they have never been able to nail it down. They reference a vehicle which they kept for two weeks for diagnosis of a "won't start" complaint, and the vehicle started some days and not other days with no pattern to the malfunction.

2005 cheverlot trailblazer has had an issue since I purchased it in 2004 with stalling out. However over the last 4 years I have had an issue of no start... Everything has been replaced by the dealer ignition switch, alternator, starter, exhaust, etc.... Last result was the PCM powertrain module supposedly the brains of the car. However the same day it stalled again, most recently my dealership took it for a week and said they could not reduplicate issue. So there again I am at the same place where the car will be fine for weeks then do a no start untill after serveral attempts and smell of gas finally the car will start. Chevrelot trailblazer have known this problem for awhile has done nothing about it ...resolve the issue and do a recall spent over $10,000 on just maintenance.. What is chevy going to do about this issue? *tr ## VIN failed ##

Erratic fuel gauge, reports no fuel even when fuel available, reports 1/4 tank of fuel available and no fuel may be available or I may have just filled the tank; also reports no fuel or low fuel when tank has been filled. Vehicle has stalled out and would not start; was out of fuel but gauge indicated 1/4 tank of fuel. Oil gauge has also become erratic; and goes from showing no oil pressure to low oil pressure to very high pressure. Have to pull over immediately and check oil level at side of road or where ever available to do so at time. Not always safe area to pull off. Both issues create very hazardous and dangerous situations for the driver and passengers in the vehicle.

The fuel indicator hasn't worked for over a year now and it has stalled and would not start for a while. After sitting for about 15 minutes it did start.

About 2 weeks ago, my 05 trailblazer began having "no start" problems. Sometimes it would start and sometimes not. During times it would not start, I could not shift it out of park. If I turn the key off and back on again it would start. But I took it to the dealership to find out what was going on, and of course, they could not duplicate the problem. So I continued driving it with this off and on problem for 2 weeks until one day I was driving on the interstate with my son, mother and father in the vehicle. All of a sudden the motor just killed! Luckily there was no one behind me and I was able to pull over to the side of the road. As I was pulling over though it was difficult because the power brakes and power steering were lost. My son was very upset and nervous. This time at the dealership they confirmed it was the ignition switch. This is the second time replacing it since buying the vehicle new. Even the technician admitted that trailblazers have alot of trouble with ignition switches but said there is no recall because it's not a "safety issue". So my engine dying while I'm traveling 70mph on the interstate with family in the vehicle poses no safety issue? I feel that chevrolet should issue a recall and reimburse me for my costs as my warranty is expired. By the way, other problems I've had with this vehicle include the idler pulley, brake lights going bad and melting into the terminal, speedometer malfunction, cd player broken, glue around license plate frame oozing and melting, broken latch on storage compartment in between front seats, faulty thermostat causing engine light to come on, and problems with the back hatch door. Next vehicle I buy will be a reliable toyota or nissan. Can't wait to get rid of this chevy.

I was stopped for my tail light being out. The next day, I replaced all of the fuses in the rear of my trailblazer. Everything seemed to work, but then two weeks later I was stopped again for my tail lights not working. I replaced all the fuses, even though it was on one side (passenger side) then checked the circuit board, still the top tail light will not work. Found out that it does not work, when head lights are on..that is why I was getting pulled over at night. Only one tail light is not working and I can not drive at night because I keep getting pulled over because of this defect. It comes out of the blue. I have noticed that my right blinker sometimes blinks really fast. Also, over the past month I have experienced a total power failure in my trailblazer. Nothing will work...its like the car was unplugged...totally out and will not turn over, no lights, radio and power to ignition...sometimes I can not remove my key or change into neutral....completely drained of all power...where I need a jump, then it works fine, but the tail light is still out when my head lights are on. I am afraid of having a total power failure when driving, especially since my tail lights will not work the head lights are on.
