 Ac blower motor works intermittently and now does not work. other people on the web have had small fire melted wires. this has been a problem with the chevrolet colorados. i had 2004 with the same problem. so as you see it is a 4 year old problem. when are you folks going to address it with gm since we as the people have some much invested in them. *tr

 There is an issue with the driver side headlamp, where it will not work under normal driving conditions. i replaced the headlamps to have the same result. also replaced the fuse for the lt headlamp with same result. the left headlamp will work in high beam mode but not in normal driving conditions. i tried manually switching on, same result.

 The brakes drag and squeal all of the time. they grab some of the time, and have temporarily locked up on 6 occasions. being abs; they don't actually lock up but do grab hard enough and long enough to make the tires chirp. the problems are not noticeable at highway speed but the lower than expected mpg and higher than expected variation in mpg makes me think they occur at all speeds. having no doubt that the brakes are defective worries me. i'm anxious about when they will fail and at what speed. on four of the six lock up occasions the vehicle had shifted itself into high range 4wd. that might have happened but went unnoticed the other two times. every time it shifted itself into 4wd (and tried to lock the brakes) was after backing up. when the vehicle is self braking; a turn of the steering wheel makes the vehicle brake harder. a turn of more than 1/2 rotation results in a grab and a chirp. if starting from a stop and turning at the same time, the rear wheels might spin. i've been driving 4x4s for many years. i know that front wheels lurch during a tight turn. that is not what this vehicle is doing. it will exhibit the same symptoms in 2wd. i think it's an electrical problem. this colorado has been to the shop for 8 electrical fixes already. the number and variety of electrical problems with the colorado model are staggering. they should be recalled and made reliable in the name of safety. unfortunately, it seems like a certain number of injuries and deaths must be reached to warrant a recall.

 Occasionally when the truck comes to a stop or coasting, the rpm gage starts to fluctuate, and the truck starts to shake. most of the time it will result in the truck completely turning off. this happens almost every day; occurring atleast 1-3 times. the first time it started was in the summer of 2009. it is really frustrating when this happens at an intersection, a light or maybe as i am turning, but it is extremely frightening when it happens while i'm going down hill or if i am on the freeway. i have almost gotten into car accidents because of this. my truck is still under warranty and i have taken it in to the dealership atleast 6 times and they return my vehicle usually clueless about what to do. they usually recommend for me to change my gas to shell, which i have been doing since i purchased the vehicle. they have re-done maintenance jobs on it, hoping that the problem will go away, but it doesn't. the engine light never goes on, which is a huge problem. recently they placed a data recorder to record when it happens, i recorded 5 incidents, and they came back normal!!! the data recorder doesn't pick it up! the mechanics are baffled and running out of ideas. they don't know what to do, nor do i anymore. driving this truck with this problem is not only putting me and my family at risk, but it is also endangering the people driving along me. *tr

 I purchased a colorado one week later my brakes went out. and i managed not to get in a crash. i took it to the dealer and they fixed it . they told me the vehicle sits on the lots 4 months and months and stuff might wiggle loose. ok i figured . three weeks later which would be 3/5/09 i left work and it was a nice day i turned my ac on and noticed my blower only worked on 2 and 3 my 1 and 4 would not work so i drove to an auto parts store about 10 miles away and talked to the guy and he told me its probably blower motor resistor switch. which the part was only 20 bucks but he convinced me to take it to the dealer . because it under warranty and things like this can short out and cause fires. so i left the store and about 5 miles down the road stuff started shorting out on my truck . than my passenger air bag deployed and than within 1/2 mile stuff was crazy there was smoke every where so i slammed on my brakes which they didn't work so i tried pulling off the side of the road my steering was locked up.and than something exploded under my dash than i started seeing smoke billowing out of my hood which quickly turned into flames . keep in mind the whole time this is going on my truck is going 60 mph and i have no brakes. so than i started seeing flames under my dash than my floor than everything on my floor started catching on fire and i started throwing thing out the window and the whole time this is going on i am trapped in my truck while its on fire my door locks are spacing out and im trapped. about 1 mile after my truck was pretty much fully engulfed than some how i managed to get y door open and jump out before i looked down my spedo said 35 mph and when i jumped out i managed to land on my feet and my truck slid in the mud 4 about 50-75 ft within minutes 4 police and 18 firefighters where there and 2 or 3 firefighters got hurt from shrapno . what scared me was i was trapped in my truck while it was on fire. i only suffered very minor injuries. *tr
