Driving from out of town and all of the sudden rps ran high and trans would not shift. It would catch finally and then slip out had to drive it in 1st gear. Had it rebuilt lasted 1 yr and now back in shop! Having it rebuilt again. Very frustrated with this vehicle. I have had to replace just about everything on it at least once some things twice. Very poor made vehicle. Please look into the transmission problems. Mechanic states it is a known fact that the transmissions in trailblazers overheat which causes these issues. How can gm sleep at night knowing they are charging 36,000.00 for a piece of junk! I have to work hard for my money and don't appreciate the way gm turns a deaf ear to their poor workmanship and design. I feel I should be compensated for the frustration!

My 2003 chevy trailblazer check engine light comes on accompanied by the low engine power light. The vehicle goes into limp mode. This is a safety feature that allows the computer to protect the engine from any damage should something go wrong. The only problem is that there is nothing wrong. This happens multiple times a day (6-8). Changing sensors doesn't fix it. I believe it to be a problem with the 2003 chevy trailblazer computer. I have read many forums with hundreds of people that have this same problem. Please look into it before it causes an accident or makes an emergency situation a fatal one.

I was at a drive thru pharmacy when my gear shifter cable (broke) and was stuck in park. It would not move. I had to get towed to my mechanic's garage, luckily about 1 mile down the road. Prior to this happening, I had noticed the gear shifter very loose for atleast a year!! The mechanic told me there had been alot of people with the same issue on their chevrolets. The chevrolet parts dealer told my mechanic the same thing. There should be a recall on the defective gear shifter cable. I could have been at a major intersection when this happened. Luckily, I was in a parking lot.

Tl*the contact owns a 2003 chevrolet trailblazer. While driving 60 MPH, the transmission slipped and would not shift gears. The contact noticed bluish-colored smoke coming from under the vehicle. There were no warning indicators present. The vehicle was taken to the repair shop and the mechanic stated that the oil line for the transmission was placed too close to the catalytic converter. The catalytic converter caused the oil to leak. The current and failure mileages were 44,000. The consumer stated the dealership agreed with unsafe defect and requested the vehicle to be investigated but was refused request by chevrolet. Updated 11/14/07

Ev cooling fan runs at a high rate of speed and does not disengage for serveral minutes while driving. The vehicle does not shift properly during this period of time. Since I am unable to get up to highway speeds, I feel I am a safety hazard to other drivers that must slow down until they can pass or I get up to proper highway speeds. I will be replacing this component at the dealer they gave me the following estimate: part cost $350 and labor cost $300. I will be asking for the old component. This problem began occuring without any warning. One morning it just began operating at a high rate when I started my vehicle and as stated, continued for serveral minutes.

I started to do a 3 point turn and when I went to put my vehicle in reverse, there was a loud clunk and I no longer had reverse and would make an awful sound when I tried. I could drive it forward, but it wouldn't shift out of low gear, driving the rpms way up. Had to have it towed. Took it to a gm dealership and they gave me the choice of a rebuild or replacing the transmission. I chose to replace because it would have a longer warranty. The warranty on this was 36000 miles... It had 42800. Currently conversing with gm to try and get them to cover some of the expense.
