On july 29, 2015 I exited the freeway, and suddenly my 2005 chevy trailblazer ext 4.2l began to stall and would not proceed upon acceleration. After calling the gm corporate office, I asked if there was a possible warranty on the vehicles transmission, they stated "no"... However, the representative did tell me that my used 2005 trailblazer ext did have the transmission replaced in 2007. This is 2 years after the vehicle hit the road spanking brand new. There has to be a problem with the chevy trailblazers transmission. I ended up spending a total of $1,600.00 for a rebuilt transmission. I am now looking to possibly trade my trailblazer in soon. Looking at the complaints here in this forum regarding the failure of the chevy trailblazer transmission is ridiculous. Gm refuses to own up to their mistake. It would be nice to see the federal safety agency get strict with automotive manufacturers. What will it take before someone listens to the consumer, a death? That could have easily been my fate; luckily, it happened when exiting the freeway.

Tl* the contact owns a 2004 chevrolet trailblazer ext 370. While in a parking lot, the vehicle stalled without warning. The vehicle was towed to an independent dealer. The technician diagnosed that the fuel pump and fuel filter needed to be replaced the filler inlet was also cracked.

Fuel gauge will read wrong. The gauge will suddenly drop down to empty and then will slowly start to rise back up after sitting on empty for a while. Also my vehicle will just stall out at red lights or when I am stopped in traffic. I will have to put my car into park and restart it quite often. This is obviously a major problem and there should be some recalls on this. This is a safety issue. I have read of peoples cars stalling out while they are driving down the highway and am personally scared of this happening to me while I am transporting my children around.

Gas guage reads empty even though full tank, battery and temp gauge also go up and down, check engine light is on. I know of more than 8 people with similar vehicles of different model years with same issue. Chevy sent a letter saying that they would pay 50% for the repair of the of the instrument cluster if the vehicle had less than 120,00 miles or was 10 years old or less. My vehicle now has 146,000 miles, but the problem started a year ago when there were only approx. 120,000 miles on it. I feel that this is a safety issue being that my wife transports my children in this vehicle and should I neglect to tell her she needs fuel, she runs the risk of being stranded somewhere with my family, or worse on a heavily traveled road where the vehicle could stall with no warning. Thank you for your time.

2005 trailblazer fuel gauge not properly working.when SUV is filled with gasoline it will indicate the tank is empty. Then after filling it will jump from half to empty not properly reading has cause me to run out of gas several times. Almost caused an accident do to a complete stall on the interstate. Really concerned and feel this should be addressed by gm before someone is seriously injured or possible killed.

In 2009, I noticed significant drops in the fuel level leading me to think people were stealing gas from my tank from my 2005 trailblazer ext. After installing a locking gas cap I realized it was a malfunction, not theft. A couple of months later the fuel gauge would not rise above 1/4 tank even when full, but spends most of its time on empty. I have stalled while driving twice because I can only estimate how much gas I have by the trip odometer. In april 2011 I learned about this investigation.

I have had a faulty gas gauge for more than a year; when I fill up my tank it always says I am on "e." this is very dangerous, I am always afraid of running out and stalling, etc. I was quoted $1200 for this repair which I don't have. I need help asap.

The car has stalled shut down twice, once at a stop sign and the other while pulling into traffic. Mechanic can find nothing wrong with the vehicle. There is no computer generated codes to indicate a problem. The gas gauge has pretty much failed, will only read between 1/4 and empty. Unknown if this is related, but have been told other drivers have experienced the same thing with this make and model.

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.
