2005 Chevrolet Trailblazer: sudden loss of power

Filed Oct 23, 2014 · Engine · 140,000 miles · FL

Pulled up to a red light and stopped. Shortly after, coming to a complete stop, the engine just shut down. No warning lights had come on prior to the engine shutting down. Just lost all power instantly. I turned the key, as you would to start the vehicle, and it started right up. Very glad it did not happen while I was on the expressway or while moving. I can't help but wonder if it is an ignition problem, as that which plagues other gm products. Also, I have the radio on while driving and on multiple occasions, after turning off the car and opening the door to get out, the radio refuses to stop playing (it is supposed to, and it used to, cease operating when you open the driver's door). I am forced to open the back vehicle door to get it to stop. I wonder if this is a related issue to the ignition, as the ignition key may not actually be shutting of the accessories.

While driving to work I felt my truck lose power a few times while slowing to stop as well as taking off after a complete stop. My fuel tank was approximately half full and it kept feeling like I was running out of gas. This really scared me because I was in the middle of heavy traffic and trying to accelerate it finally kicked in and I almost ran into the person in front of me. Please let me know what I can do about this? Thank you very much.

Sir/ ma'am, I noticed recently in the news that several gm product lines have been plagued by faulty ignition switches causing the vehicle to lose power and/or cut out. I implore you to look into the trailblazers. I emailed gm while I was deployed (2012) and they gave me the runaround saying that it is not a documented problem, as expected. A simple internet search would show that a lot of other trailblazer owners have bad ignition switches/ electrical issues that cause the vehicle to lose power at all speeds. My wife lost power going about 35 MPH and I had my two children along with her. This is just one example, on one occasion. Granted, I do acknowledge this problem is intermittent, it still occurs at random and at all speeds. Gm tells me to go to a dealer and have them look at it. I refuse to pay gm any money to have a dealership rip me off for an ignition switch that is flawed and replace it with the same faulty oem style/model number. I have ran a scan tool looking for codes and it doesn't have any. Like stated previously, this is another line of gm that is plagued with ignition and electrical issues that gm refuses to take ownership of. The mileage I have entered is approximate. I cannot remember exact numbers, but it has happened for years, intermittently. When the vehicle has coasted to it's final destination after losing power, it starts up and drives normal again after it is put back into park. Also keep in mind that it doesn't show any check engine lights, indicating a problem or need of servicing. Again, please look into this product line as I know the result(s) will show that gm is liable and I don't want any fatalities because nobody spoke up about it.

I was driving on the highway at 70mph when my engine suddenly cut. I lost power steering and brakes. Luckily, traffic was clear enough and an exit ramp was accessible; however, I had a very difficult time steering to the side and thought I was going to be unable to brake. I was stranded on the off ramp for hours by myself in 40 degree weather and no heat. My gas gauge has not worked for several months (see my first complaint 10408603). I have been guessing at amount of fuel by miles driven. I should have had at least 30 miles more of gas. Obviously, this is not a safe way to gauge fuel level. It will cost $600 to have the fuel system fixed. Because this is an obvious problem with trailblazers, I feel the company should issue a recall.

Three out of six dashboard gauges don't work. Included are speedometer, tachometer, and gas gauge. The vehicle isn't safe because you don't know how fast you are going. Because of the faulty gas gauge, one never knows when or where you will run out of fuel. This opens you to running out of fuel in a dangerous location and also the loss of power steering and power brakes. This has been an ongoing problem since approximately 2008.

I bought a 2005 trailblazer in 2006. There was alot of hissing from the speakers, which they replaced but it never fixed the problem. I already fixed the oxygen sensor and now I notice the lights go dim and bright and it seems to lose power. It only has 36,000 miles on it. Everytime I bring it in it doesn't happen so no one knows what it is. I have 2 small kids and it's cold in wisconsin so if it ever dies in the middle of the country who knows what could happen.
