2005 Chevrolet Trailblazer EXT 370 electrical problems

Filed Oct 12, 2018 · Electrical, Fuel system · OH

The whole instrument cluster does not work anymore, does not let me know how fast I'm going or how much fuel I have, oil pressure gauge doesn't work, temperature gauge doesn't work... Why hasn't this been recalled? This is very dangerous, considering I have 4 kids that are constantly in the car with me and I have no idea what is going on with my vehicle?? And it also tells me that my fuel level is low, even after I fill my tank. This seems like a very common problem in these vehicles, why has it not been considered a safety issue????

For the 3rd time the cluster has gone out. This results in the speedometer, temperature gauge and others to stop working. Each time I am expected to take my vehicle to a chevrolet mechanic for diagnosis and part replacement at $700.00+ each time. This model has no recall. I am fed up with paying this much every 3-4 years for a defective part. There has never been any sign before it goes out.

Our 2005 chevy trailblazer speedometer stopped working. This has happened on many of these vehicles. It is a very expensive fix and it's a danger to drivers not knowing how fast they are traveling.

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.

Electrical issues:vehicle dashboard lights will show door gate open, doom lights wil be on, ringing bell when the door would be open and yet its actually closed, as all continues to go at any given time when the vehicle is in movement. Speed odometer gage doesn't read when vehicle is in movement and the gas gage doesn't read the correct level of showing how much gas is in vehicle. This is a big safety issues cause it has me worried of not knowing how much gas I have before it runs out of gas risking myself and others because vehicle all of a suddenness loses speed and shuts down.

My speedometer and oil gauge just quit working for no apparent reason and does not come back on until hours later.

Since october 2014 the speedometer would randomly start up at different initial points. Some days it would start at 60 MPH, 10mph and recently it starts up at 110mph. When the vehicle is in motion the needle would move when accelerating but the readings are completely inaccurate. I have read various online blogs of this same incident happening to numerous chevy trailblazers in general. Gm does not have this problem as a recall therefore I would formally like to make a complaint. Thank you for your time.

My husband bought the car used for me for christmas 2013. I was driving through the city when I looked down to see how fast I was going the speedometer said 0 it remained that way until the next day. I started it the next day it seemed fine but after a 1/2 mile I noticed I sped up and speedometer was going down until it finally went to 0. I have been driving with a speedometer that doesn't work. I looked online and seen that a lot of other consumers were having the same problem some with much less mileage.
