What Owners Say
"For the last 6-7 years the security system will lock out on its own for 10 minutes. This is a known issue with the master control module for this model year. GM refuses to replace it. See more in the forums."
Anonymous, AL (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"If it even thinks it is going to rain the security system will not arm says a door is open. I have pulled all the carpeting up and checked all wiring and found nothing. Dealer says maybe a body control module but just a guess"
Joseph F., OH (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"Key fob not working and problems with the electric windows"

Sean L., OH (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"I went to use my truck the other day, (after taking to car cover off of it), and found that my dash gauges are non-op. After looking on-line at a forum, I tried a couple of the recommended fixes to no avail. I have a Toyota and a Subaru of about the same age as my truck, and neither has had anywhere near the problems as my Colorado. Goodbye GM products"
Scott R., CA (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"There are times when I am driving at night that the dashboard will go completely off."
Paul D., PA (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"The airbag light kept coming on. The problem had to do with the wiring cables in the small side doors. Opening and closing the doors repeatedly caused the wires to break. I have had this problem worked on 5 or 6 times over the past 3 years"
Anonymous, TN (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"Sometimes the gauges flash from bright to dim and flicker. The dash light scroll wheel will have no effect on the brightness of the gauges, almost like a bad ground"

Vicki L., NV (2005 Chevrolet Colorado None 3.5-L 5 Cyl)"Seat Belt tensor due to too short wires to extended door. Speaker wires and tensor wires break. I had to rewire with myself. Dealer wanted $100 to tell me the problem. Auto zone diagnose it for free"
