Car felt "stuck" in gear, wouldn't accelerate, low on transmission fluid. Added more fluid, replaced speed sensor, camshaft & crankshaft sensors. Still having issues with rpms going high, car slamming from one gear into another. Also cannot run heat while driving, fan draws power & causes engine to stall out. Car also burning through gas very quickly.

On several occasion over the past year my fuel gauge in my 2004 chevrolet trailblazer lt has read inaccurately leading to breaking down due to the vehicle running out of gas while the gauge was still reading at least 1/4 tank moments before the engine stalls. On all occasions I was driving on the freeway the gauge showed 1/4 tank and then all od a suddenly dropped to e with the fuel warning light coming one. Within a few miles of this sudden drop and the warning light coming on the engine would stall due the vehicle being out of gas. I have complained to my local dealer on several occasions and all they have offered to me is to replace the sending unit, which in this model is integrated with the fuel pump at the cost of almost $800. This seem wrong to me. Now that I have read that this seems to be a problem on these types of vehicles I am even more upset that the local dealership told me my issue is an isolated issue and they have never heard of any problems with the fuel gauges in these vehicles.

Check engine light - for over one year now, and 4 various mechanics, no once can figure out why my check engine light comes on. I have replaced two air sensors (actually 3 - one was bad)... I have spent close to $1,000 to get this fixed - but the dam light continues to go on (intermittently) sometimes it's on for a month - off a day - on two weeks - there is no pattern. The last time the light came on, my car began stalling in traffic and stop signs. Last mechanic spent 5 hours tracing all the codes back - nothing. Next day had another mechanic check codes and the engine running cool as well as a few others showed up. If no one can figure this out - where is the recourse. I feel like I am being scammed over and over. I stalled on rt. 24 slowing down in traffic - and was almost hit by a box truck because I just sat there. Who can help direct me to a repair which will ultimately end this issue? Now, the lights off this week (watch, now that I say this it will come back on). The only thing I notice is that many times the light turned off after I filled the tank. So, is there anyone out there who knows what's wrong (referring to mechanics who take us for a ride $$$)? I challenge anyone out there to figure this out.

The vehicle was purchased in sept 2004. In march 2005 I started noticing it was hard to start in the morning when it was cold and it idled roughly and would stall when I pressed the gas pedal to accelerate. The dealer found nothing wrong with it then. In april 2005, with 9400 miles on it, the service engine light came on so I took it back to dealership. They cleaned out (flushed) the fuel system and proceeded to tell me not to buy "cheap gas" because sometimes it will have particles in it that can clog up the fuel system (then what is the fuel filter for?). Since then I have had the fuel system flushed three more times. I probably could have had it done more times, but it is extremely inconvenient to keep going to the dealership and being without a vehicle, so I just dealt with the rough idle and hesitations. I buy gas the same places as everyone else in my family, yet I am the only one experiencing this problem. I bought fuel injector cleaner and put it in the gas tank every couple of fillups. The dealership has offered to replace the fuel injector that keeps clogging, but of course none of the mechanics ever made note of which one it was. So when the problem recurs I must take it back to the dealership again.

I have many electrical issues with my 04 trailblazer from my window lights on the drivers door and the passenger door. I have had my radio replaced because it melted one of my cds. My head lights work when they feel like it same with the rear wiper. It has stalled out in traffic on me. I have also heard that in most 2000 to 2006 trailblazers the reason for the electrical problems is because water is running down the passenger side door into the dash and hitting one of the main wiring harnesses causing it to have many electrical issues. I heard this from someone who has an 06 trailblazer that just had it a replaced for $700.00 to fix and was told that it will just have to be replaced in a few more years because they cant fix the problem.

We have a 2004 chevy trailblazer, that originally began with the speedometer appearing to be stuck for a few days, would gradually decrease. Followed by the RPM having the same problem. Today, 11/28/08, all gauges lit up, warning bells rang, and then the entire instrument panel shut down. There was a recall for the silverado for the same year, but trailblazer owners are required to pay the repair bill for a faulty instrument panel. Being unable to know your speed, how much gas you have, or if your running low on vital fluids seems to be pretty dangerous to me. The fact that gm will repair the silverado, but not the trailblazer despite the fact that they are both in the "truck" category is ridiculous. It seems to me that any one of these problems can lead to death or injury of the occupants of my vehicle, either by fire, stalling in traffic and being hit by another vehicle at a high rate of speed, or because of the inability to ensure that my vehicle is operating with the proper vital fluids, as well as maintaining a safe rate of speed. My teenage children also drive this car on occasion, and though they've been driving for 3 & 4 years, they do not have enough experience to operate this vehicle safely. There was a recall for the brake lights, how can they justify that when people are driving around without properly working instrument panels? The solution being offered is for the consumer to pay at least 500.00 to repair something vital to the safe operation of the vehicle, but gm will replace the taillight/brake light that costs pennies on the dollar.

2004 chevy trailblazer. Intermittent engine stalling since new. Many service visits to chevy dealers to fix, however mechanics stumped. Local gas station mechanic found the problem having to do with components in the emission control / vapor recovery system. Now chevy needs to figure out the cure. In the meantime I get to drive around with the "check engine" light on. I guess this is better than being crashed because my car stalled in an intersection or on the highway. Chevy mechanics and engineers need to get the "duh" award. Very bad customer service and diagnostics performed by chevy. I would still like to have the check engine light to go off, and have the engine not stall if that is possible. Please send info to have this done if possible.

My trailblazer has stalled (cut off) now 4 times and it is getting old and unsafe. When you are going down I-95 and it cuts off. Imagine having no powering steering and trying to get out of the way before you get hit going 70 MPH! And chevrolet will not take it back or help with a trade! I may contact the papers and have someone look into this!!

Engine stalls at various times for no reason. Have had it into dealership many times. Dealership has been unable to isolate problem. Service engine soon light came on after first stall. Dealership reset computer. Since then, the engine has stalled at least 5 times. Ses light has not come back on. Engine usually restarts after approx 5 minutes.

Transmission shifts hard from 1st to 2nd, sometimes when at a stop it stalls before taking off, sometimes RPM bottoms out. 4 wheel drive only used about 3 or 4 times, each time it stalled before going into 4 wheel then would not come out of 4 wheel for about 2 or 3 minutes.
