One problem related to starter solenoid has been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
I am extremely disappointment and afraid of my Trailblazer at this point. We purchased the vehicle used and within a week of having the truck it started dying at redlights. Out of nowhere the truck just shuts off in the middle of the road. It has got to the point now that it does it while the vehicle is actually in motion. I have 3 kids and this is not safe! I lose total control of the vehicle. The headlight plug has burned up twice on the driver side and it has been replaced. The electrical is seriously in need of a recall do to the back door speakers never working since we purchased the truck (which the dealer promised to fix) along with the rear a/c (which the dealer also promised to fix! I cant afford 900$ in labor for whatever is making my truck shut off but if it doesn't get fixed it will be the death of me! reading codes on obd2 scanner of poo14 and p0016 incorrect camshaft timing wiring problems (harness/wiring) in intake timing control valve control solenoid system continuous oil flow to vct piston chamber failed timing valve control solenoid (stuck open)- now what do I do. .
