Chevrolet Trailblazer Problems

Electrical & Lights -- Verified

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.
On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 ...

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Chevrolet Trailblazer Reviews

I have owned my 05 Trailblazer since end of 2005 (I am 2nd owner). First few years no problems. Around 2009 I started having check engine light show up on a regular basis. Now it occurs about once every 6 months. Getting expensive to own! I have had electrical connection issues with the headlight (melted connectors), oxygen sensor failure (twice now), bad coils, broken plastic parts on the interior, overheating with a/c on (t-stat problems), etc etc. I have always been on top of maintenance with my rig so I'm pretty disappointed in how it is performing now, especially since its just over 130k miles - that's not very old! Aside from those issues, I am thankful to have a dependable vehicle that has never left me stranded!

I have a 2004 chevrolet trailblazer LT we purchased in 2007 we have had nothing but complications it started of minor now its major we had the transmission rebuilt and now the 4wd is bad and this was the way they sold it to my husband, we are also having the power steering pump and acurators replaced for the a/c , we have this great mechanic who is helping us with all our problems at a very low cost that is why were able to fix this LEMON!!!!

My trailblazer has been a constant reminder of why you need a mechanic in the family. Around 32,000 miles the passenger window fell into the door. The power window's plastic parts were crumbs inside the door panel. Prior to the window problem, my sound system's speakers played musical chairs. I have one speaker that is working at this time. 70,000 miles and the gas gauge no longer worked. Now when the engine is running the "humming" sound is so loud that someone standing by the car can hear it. When I drive away the sound becomes louder. I feel that I've made quite a bit of lemonade, but lemon is not my favorite flavor.

Overall the car has been a good car but I did have most of the problems listed for my year. CD player failed(2009ish)Sunroof failed (2010ish)with no replaceable parts only full replacement available (as per goodyear repair) Brakes as of 2012-2013 have been done twice (front)needing another FULL brake job.(supect master cylinder?) I did not have the 4wd switch problems, TG! Front axle driver side has been replaced seals failed (2013)not bad. Electrical some issues with head lights.. only had to hit it a few times and they dem but not bad just strange. Engine itself has been a champ outside of the exhaust manifold. AC/heat has worked great except AC is poor at idle. Steering great Suspension mushy/bouncy since I have owned it, even after front strut replacement.

I purchased this SUV with 38,000 miles on it. I now have 129,900 and it is still going strong. I am just now needing to replace the front brakes. My gas milage on the hiway averaged to 18.2 mpg. Have not had to change spark plugs yet, but did remove and regapped them. I an sorry they quit makeing the TrailBlazer. It is great for city and some country driving, with good groung clearance. I have the 4.2L6 engine.
