i just took my 04 colorado in with 61000 miles and the check engine light was not on at the time, they were still able to read the code, and they have replaced the head at no charge, it was only in the shop for 2 days.

Stay with an American company. We need to support our own country not Japan.

Thanks to longrunner1 for the details about cleaning the throttle body. My 2005 Colorado (55K miles) developed the same check engine code & a noticable low idle speed. I followed the cleaning advice & the problem is solved! Not hard to clean, but a little awkward to hold the plate out of the way & do a thorough job. Surprising amount of dark-brown deposit in there - I guess from the oil vapors.

Hi, I'm new to this forum and I was hoping to get an answer to a question and maybe some advice. Does anyone know if GM is covering 06 colorados\canyons in canada with this head/valve problem I'm reading about? My wife really likes these trucks and up until I read some of the forum discussions we were actively trying to find an 06 crewcab. They go for around $21,000 can. w/ 35- 60 thousand kilometers on them, whats kind of scary is that there are alot of them on the lots in and around my area, could be because they are just coming off lease since they are 06 or.... maybe there are other reasons? Nobody seems to be aware of the head issues that I have mentioned it too (dealer salestaff). I have been trying to steer her towards an Avalanche or Silverado but shes only 5 ft tall and doesn't seem to feel comfortable in a fullsize pickup,I like the interiors in these a whole lot better but this gas mileage is miserable, we are currently paying $4.09/Gal for gas so this becomes a real deciding factor for us. Any input will be appreciated !

If I were you , buy a different truck. These trucks are constant problems. Engine head defects, Wiring defects, ABS defects etc. This is ISUZU not GM and frankly it is garbage. Save yourself, get something else!!!!!! Take it from me my crew cab LS is a 2004 with only 42,000 miles on it. I dont trust it and they will leave you broke down on the roadside.

I also agree that you should stay away from these trucks. If you want to buy a used GM crew cab compact truck, you may be able to find a low mileage 2004 S10/Sonoma crew cab. 2004 was the last year for these trucks. These trucks had some problems (e.g.wheel bearings) but GM's 4.3 V6 is a good engine. Good luck.

I also have 06 colorado and I have had ongoing engine problems in which nobody could diagnose correctly so over $3000 later they replaced 2 ignition coils and it has been running ok since, but I did have the complete head replaced which was covered under a Recall. But my advice would be to have your wife look at a silverado, I am also 5ft tall and have drove them and they are very comfortable and better with gas mileage, the colorado gas mileage is horrible and taking to GM about the engines is like talking to a wall with no help with them at all and the colorados are well-known for engine problems. In fact, I am in process of hoping to trade my colorado in for a silverado. I hope this helps you. Good Luck.

GM sent me a letter, re the head, it should be under warranty
