| On sat oct 1st 2011 i was traveling east on the interstate at about 75 mph when all of a sudden it felt like i had blown a tire. the steering became rather sluggish and i pulled over to the side of the road. i got out checked all the tires and they all looked ok, so i got back in the vehicle.my grandson and his friend were in the back seat it was a crew cab.i noticed that the 4wd indicator on the dash was on but i had not switched it from 2wd it had done it on it's own . i tried to switch it back into 2wd but upon moving the vehicle it still felt like it was in 4wd. i decided to get the vehicle off the freeway so i could go slower and get the vehicle home, so i exited the fwy about a mile later and got on the old hwy where i could go 35 mph. my daughter was behind me in her car. about 5 miles down the road my daughter starts flashing her lights so i pulled over and she cam4e running up and told me my vehicle was on fire , i ordered my grandson and his friend out of the truck we left immediately , and backed off about 200 feet, you could see smoke coming from under the vehicle and fire dripping from just above the transfer case below the front passengers floorboard area. the fire spread and the vehicle became fully engulfed the tire melted the leather interior was completely vaporised needless to say it was a total loss. my theory is that the switching mechanism for the transfer case is defective it should not have switched on it's own at 75mph. i almost lost control of the vehicle when it did. that caused some kind of damage internally in the transfer case. when i drove the veihicle it heated up until it was red hot and caught the fuel filter on fire which eventually ruptered spread the fire and destroyed the vehicle. | |||

| As i was driving my 2004 chevrolet colorado, my transmission would not shift into over-drive. the check engine light flashed, but no message was shown on the message center. i took my truck to the local dealer. after talking to the service department yesterday, they informed me that there was a small recall for this type of problem (which from what they told me, involves some gaskets and pins of some type). my truck is being repaired at no cost. but in checking your recall list, i found no colorado. is this something that everyone with this type of drive train should be made aware of? or is this such a minor issue, that a major notification is not warranted? *jb | |||

| 2004 chevrolet colorado, new purchase, drove 568 miles engine idle eratically, engine light appeared and then engine stalled. took to dealer and they reprogrammed computer, since that i lost 1.6 mpg and engine will not idle until vehicle came to complete stop. engine rpms do not drop between shifts like it did before reprogramming and vehicle lunges when clutch is released if not carefull or give it extra time for the rpms to drop for a smooth engagement. and when you need to let off the gas pedal the car keeps going like you are still accelerating, especially in fourth gear, which can throw off timing and cause you to hit brakes to slow down or push clutch in to keep from going ahead at same speed until rpms fall, when i bought the vehicle, it did no of this , the dealer has made several attempts to correct but says the problem is with the gm program. and they can not do anything else for me.*ak | |||

| I bought a 2004 colorado in march of that year,on dec. 31st 2004 i had to replace the two front tires at my expense. they had worn from the inside out the tires had 23,000 +miles on them. i complained to the dealer and they told me that there was not anything wrong. in march 2005 i had to bring it in for the same thing with less miles on those tires 17,000 miles and they still insist that there is nothing wrong. i soon will have to replace these tires before winter. the dealer tells me tires need to be rotated more often. i've owned other s-10 models with over 250,000 and haven't had the problems i've had with this type of problems. i did have other problems with this vehicle from door wiring, replacement of o2 sensor,front axle seal driver side replace,headlights,fog lights and tail lights all have been replaced within the first 20,000 miles. *jb | |||

| Took my truck in for tire rotation and check alignment on 3/12/2005. maintenance is current. turns out both front tires (general tire 235-75r15) were worn down to the steel belts on the inside edges only, with the steel belts actually sticking out in there. i do no off-road driving- only to and from work 2 miles daily on the highway and an occasional trip on the highway to fort collins (260 miles round trip once per month) - and these tires only have 15,000 miles on them. was told by mechanic we were very lucky that these didn't blow on us on the highway. also, mechanic reported that there is a left front axle seal leak. took the truck into dealer on march 18 for repair, but dealer did not preorder parts, so i must return this week. i went ahead and had the tires replaced in spite of the bumper-to-bumper warranty because i didn't dare wait. i also had an alignment. (my first alignment check showed no problems in october.) the tire thing really disturbs me because, in 36 years of driving both new and used cars and trucks, i've never had this happen. i've never had an axle seal leak in a reasonably new vehicle either.*ak | |||

| The rear end of my 2004 chevrolet colorado jammed while i was backing out of my driveway, causing the gears to shatter, the rear axle to crack, and the driveshaft to drop out of my truck. since i bought the truck, i noticed vibrations and instability in the back of my truck, and sometimes the engine stays in 4wd when i shift out of it. the entire rear end of my truck has to be replaced, and gm is refusing to cover the repairs, even though the truck is under warranty. this was a very dangerous incident, and would have been worse if it had happened on the highway. *tr | |||
