While a class action law suit sounds interesting to me, I wonder how we can sue when our vehicles are as old as they are and have lasted for thousands of miles.
My vehicle still sits not running as I didn't want to spend another $600 to find out it still wouldn't run. My mechanic was telling me it was the throttle body and I am having a hard time spending $600 for a vehicle that is not worth much more than that... I am debating about having it fixed and then selling it or just selling it for parts. BTW - 2 days before it broke down, I just spent about $600 in new tires so I know I want at least that amount back. I could fix it and someone could drive it for months without a problem, I just got tired of fixing and fixing and fixing.

You can add me to the list. I just bought a used 2002 Trailblazer which ran fine for the first week and then the light and low rpms came on this weekend. After some quick googling I thought it sounded like a problem with the Throttle Actuator Control but after finding this thread it seems like the list of fixes (or attempted fixes)is quite long. I'm nervous about taking it in now as it has fairly high mileage and I don't want to put more into the vehichle than it is worth. Everyone on the thread has listed the same problem but can anyone tell me or send a link to most-likley solutions - I'd like to ry to narrow things down for my mechanic

I have a 2003 TB LTZ which Im told is very rare. She has 157,000 on her and yesterday I was warming the engine befor driving and she turned on, idled for about 2 min and then just died like her fuel pump went. I got her fuel pump and fuel injectors changed, starter, altinator and fuses all checked but she still wont start. Sounds like she wants to start but wont. Has anyone else had this prob? does anyone know what might be wrong with her? Please e-mail me if you can help, thank you amy-spears@hotmail.com

Well well well! I too hav an 03 TB with reduced engine power & check engine light. Coupled with that is an electrical issue that boggles the mind. My key gets stuck in the on position, the gear selector button will not depress, the blower motor will not come on and the service 4wheel drive light is on. The car starts up fine. If you push the cigarette lighter in, the dome light comes on, the doors lock or unlock and the battery light comes on in the dash! I have replaced the ignition switch and that did not fix a thing. Are there any answers out there? Would be greatly appreciated. No wonder there is an inordinate amount of these vehicles in the junk yard burned up? warrenscaine@aol.com

I have a 2003 Chevy Trailblzer that has been nothing but problems. I just spent $1,253 on it with 3 differnt mechanics that can not fix the problem. The reduced engine power ligth comes on and I lose power. I have to pull over, put hazzards on and turn off car and re-start it. I can't even pull out of my driveway w/o this happening. Please help! I have been pulling over every trailblzer I see on the road and most have the same problem. I am ready to start a class action lawsuit. I replaced the gas pedal sensor, the camshaf sensor, throttle body unit, computer, fan clutch, fuel filter, mechanics have checked every wire and they still cannot fix. I have about 6 others phone numbers with the same problem. Any help from anyone would be greatly appreciated. If you are having these problems, please email me: carrielgagne@yahoo.com. Please put Chevy Trailblazer in the subject. Lets get our vehicle fixed or be compensated for the Lemons that we all have. By the way all the trailblazers I have pulled over are from 2002 to 2007 and all have similar problems. Please HELP! if you know what will fix it, please also let me know. I'm very frustrated!

Add me to the list. This is happening to me too. My fan clutch has been clicking for awhile. The mechanic said this will eventually cause problems. I am going to replace it and pray that fixes it. However, unless people here are just blowing off steam and have no intention on pursuing a class action law suit, count me in. RASKINSM@hotmail.com.

I just bought my 2003 Trailblazer LS. After driving it for around 30 min and letting it sit and run for about 30 min it never stalled once. After paying for the vehicle in full as is, i noticed the Trailblazer stalls and the Reduced Engine Power light comes on. It seems to only do it sometimes and mostly only when i stop. The dealer that i bought it from replaced the fan clutch for me for free the same day i bought it. The Trailblazer only has 91,000 miles on it. I need help, i do not want to take it to a dealership only to be convinced it is something its not, money is tight and i bought the truck thinking it was a good solid family vehicle and it hoping it was a good investment. Please if anybody has any advise for me on what i would need to actually fix this problem my email is BigSagraves@yahoo.com Also i would like any information on the class action lawsuit. Thank you for taking the time reading this and replying to me any help is welcomed on this matter. Thanks and god bless

I have a 2003 trailblazer with 217,000 miles. It also cuts out and says reduced engine power. It's very aggravating cause you have to pull off and restart the truck. The Chevy place cleaned the throttle admit didn't fix it. Now they want to replace the throttle which is about 500 dollars. I am very interested in the law suit. Please email me some information. kristiejohall5@hotmail.com.

I'm glad to know that I am not the only person with this fan clutch issue!!! I'm sure that my fan clutch and water pump went out while driving on the highway.. I have put so much money into my 03 Trailblazer and 2k later find out the issue is the clutch fan. If there is a class action someone please email me the details.

UPDATE - I replaced the Ignition Switch (just the electric part, not the tumbler) and my issue is resolved.

My '04 Tracker had the following symptoms
-Severe power loss (unable to make it up a driveway)
-Check Engine light
-If I put the car in park the gear indicator light would indicate 3rd gear
-Key would not release from the ignition

Took it to the dealer and they got 7 codes related to the transmission and fan. Luckily their recommendation was the ignition switch which I have replaced myself about a year ago. The dealer wanted $350 for parts and labor. The ignition switch itself costs $40 and it can be done in 20 minutes without getting your hands dirty. Everything is done within the cabin of the car (just have to remove the lower cover to the steering column).

This link on the trailvoy forum will walk you through how to do it:
http://forums.trailvoy.com/showthread.php...

Don't every replace a throttle body, fan, or computer, without replacing this $40 part first. This is the 2nd time I've had to replace it and last time the symptoms were slightly different (the A/C blower stopped working and the 4 wheel drive switch was unresponsive amongst other things).

I don't know why trailblazers burn ignition switches so fast, but I'm going to keep a spare on hand and try replacing every time the car acts up.

Ditto to all of the post above. I have a 2002 Trailblazer w/166,413 miles with the reduced engine power and check engine light issues as well. Change camshaft sensor didn't fix issue. Transmission is been replaced. transfer case has been replaced. fuel filter has been replaced. I was looking to replace the o2 sensor and the catalytic converter. After reading this thread I don't know what to do. If there's a class action count me in, jmkier@yahoo.com.

I also have a 2003 Trailblazer, with same problem. Engine light comes on, loss of power, and have to pull off the road, wait a few minutes and restart. this happens about 4 times in a day, then won't have the problem again for a couple weeks, when it starts all over again. Mechanic says lots of codes coming up, has not been able to narrow down, so does not want me to incur costs that won't fix it. Have already put some $$ in on diagnostic's. Help!! I am original owner, truck has 246,000 miles. This is dangerous on the freeway! Info on the class action suit, can someone send to me?
