I own a 2005 Chevy Trailblazer LS and I have had this happen to me only a couple of times. However, I previously owned a Jeep Grand Cherokee Laredo and this also happened a few times. This may sound weird but it has something to do with your gas cap or door. Next time it happens, try this. First, turn the engine off. Then open the door to the gas, take gas cap off and then replace. Make sure it is correctly in place then shut the door back. Then just restart your engine. The "check engine" light should go off. Very simple and it has always worked for me. I also noticed that it usually only occurs just after filling the tank completely. My problem right now is the cluster. I was hoping there was a recall on it since I have heard that many have complained about this same problem. My speedometer works on occasion but the fuel gauge stays on empty at all times and the oil pressure gauge stays at 120. Its really irritating and my warranty has also expired.

It could be that the gas tank has a crack in it Chevy will replace it for free or the catalytic converter could be going bad they will also replace that for free. It could be as simple as the gas cap not on tight enough however the two things that I mentioned before went bad on mine.
#481 of 665 2006 Trailblazer LS Gas Gauge Problem & Engine Whining
Mar 27, 2008 (11:04 am)
My 2006 Trailblazer LS started acting funny about a month ago. The gas gauge will go to the correct reading and then after about 1 minute it will go to empty and the amber light will come on. I guess I should take it in to the local chevy dealer, has anyone had this similar problem. Also there is a whining noise coming from the engine when you give it gas. I'm no longer under warranty so any help would be appreciated. This has been a great vehicle and my first Chevy. Thanks!

Love my 02 Trailblazer as well. Currently have over 200,000 miles and runs as good know as when I first bought it. Beautiful Black Onyx color. Never had any major problems. Just change all the fluids when recommended.
Anyway, according to past posts the whining noise comes from a worn idle pulley. My 02 has the same noise but not a big issue. Have not experienced the gas gauge problem. Maybe somewhen else could steer you to the right fix.
Hope this helps.
#483 of 665 Rear Window not Locking
Apr 01, 2008 (3:44 am)
Hey There! I have an 07' Trailblazer with only 1 problem to date. The rear window won't lock. Unlike others, the alarm does go off when opened. When I do lock it, it sounds like the lock engages. Am I doing something wrong or is this a common problem? I didn't find much when searching for this before posting this.
Thanks for your help.

I was wondering if you had the BOSE sound system in your TB and if you have had the "no sound" problem again with it. If it happens when it is cold outside and the vehicle is cold (below freezing) it is a problem that GM issued a TSB on but they have since either lost it or deleted it. I have been chasing this problem on my '04 Bravada. I have found references to the TSB online in a couple of places.

I have had my 2003 TB in the shop several times for no brake lights and no cruise control. They finally found the problem, but of course it wasnt covered by the ext warranty. I got it fixed elsewhere alot cheaper. Now I have the passenger side temp control panel light out. The driver side still works ??? Any suggestions? Also, the front end ( I think it has to do with the brakes) is making a squeeling noise the majority of the time that I drive it. I was told it is just dust. Also, something in the rear end rattles everytime I hit any kind of bump. Sounds like something is ready to fall off any minute. Of course, the dealership mechanics tell me they cannot find anything. I am tired of spending the 99.99 deductible to have them tell me its not covered by the warranty or they can't find anything...must be in my head. Also, I am very disappointed with the gas mileage! Also there is a rattling in the back passenger door panel when I close the door and rattling in the dashboard on and off. It has just started "choking" a little when I back it out of the driveway and change it into drive, almost stalling. I have really wanted to get rid of this vehicle and get a foriegn SUV but I owe too much on the TB. I will never purchase another GM product.

I have an 03 TB and had the same problem. Check engine light, tried making sure the gas cap was on right, everything else the dealership told me to check. Turns out it was a hole in my gas tank. Thankfully I had extended warranty. It would have cost me 1300.00 for the new tank had it not been covered. Sorry to have to tell you that, it's not good. Hopefully that is not your problem

Hey, I also have '07 Trailblazer with rear window that won't lock and won't alarm. Yours is the first posting I've seen on this issue. I assume I need to bring it in for service. Sorry no help.
