Swap? by jimbo1490

I'm seriously considering a swap to Isuzu NPR power. The 4cyl turbo will fit right in and get me well over 30 MPG, more than offsetting the higher cost of diesel. Oh yeah, and it WON'T BREAK!

It sounds like that valve seal issue that was supposedly corrected with the 2.9 L model engine or slightly before with the late generation 2.8 L if im not mistaken.

2005 Colorado dripping something?? by jeepgirl05

I am looking for a small 4 dr. crew cab p/u. Had my sights set on a Colorado, until this morning. Its an 05 w/43k miles. Got to "test it" for weekend. This morning I go to start it, nothing happens, won't even turn over. Let it sit for couple hours, go back & try it again, this time it starts, but smells like something is burning so, no dashboard lights come on, shut it off, get out & notice oil like stuff all over ground. Smelled like burning rubber, ick..call the dealer to come & get it. They come n get it want to charge me for towing, which i refused to pay, its there stupid truck. The tow guy said the stuff on the ground was a mixture of oil, transmission fluid & gas & there must be a hole somewhere in the engine area They haul it away, the dealer called asked what i did to it to cause this mess. I drove it two days, no off-road or anything like that. Have another one...different dealer its an 06, see what it leaks, then going back to Jeeps.

OK all here's the deal on the cylinder heads. My 06 Colorado crew cab 4x4 z71 package 33,000 miles started with a check engine light, diagnosis misfire cylinder 5. I took the vehicle to the dealer here in Little Rock AR, they supposedly made a repair to the fuel injector. Drove to visit family in St. Louis check engine light came back on, I stopped at a St. Louis dealer, Lou Fusz, who told me of the cylinder head problems. Because of the extended time to make the repair he suggested I have the work done when I got home to Little Rock. In LR at Crain Chev, they again supposedly repaired the fuel injector, another check engine light 24 hrs later and I returned to the LR dealer and insisted they look for cylinder head problems. Final diagnosis cylinder heads leaking and valves were bad. A Chevy tech bulletin recommended replacement, this was under warranty. The dealer kept my truck for 3 weeks so make sure you get a rental car under your warranty.
After getting my truck back everything seems fine but I called Chevrolet Customer care and eventually got a Victoria Castro. After much discussion GM has given me an extended component warranty on the engine for an additional 3 years or 60,000 miles from the date of repairs.
When you get the customer care rep they will try to sell you a discounted extended warranty and insist the warranty cannot be extended for free. Ask for a supervisor and be very persistent. It took me about 3 conversations and much persistence with Castro to get the extended warranty. Make sure you point out this has been an ongoing problem since 04 on the Colorado.
Also just for FYI the dealers and customer care reps will all act as if they know nothing of the valve problem but there is a tech bulletin issued by Chevrolet for the Colorado and they will extend the warranty even after repairs are made.
 
Good luck to all!

2008 Canyon engine by donnyr

I just purchased a 2008 Canyon in December and was pleased with the truck, but noticed each morning or after the car cooled down, upon cranking the engine I have a knock in the engine only briefly, but yet a knock. I went to the dealer and asked to crank other Canyons on the lot. I cranked approximately 5 with no noise. So I informed service that my Canyon sounded like a diesel when cranking cold and smoothed shortly after. First they informed me it was the catalytic converter, then fan noise, then called me back and wanted permission to drive the truck 35 or 40 miles because of the fuel injectors. The truck has less than 1000 miles. They gave me a truck to drive and I've had that truck for one month. Now the dealer is telling me that my truck is drivable, for me to come get it, and they would have an engineer later on to come in to see the truck, but that I should drive it until he comes to see it. Any advice on this matter would be greatly appreciated due to the fact that GM had to buy back my GMC Envoy three years ago. Should I get my truck or should I leave it with the dealer until they find the problem? I am afraid that driving it might damage the truck or possibly breakdown. Signed, HELP!

I'd try to get them to take back the truck and exchange it for another new one. The longer this goes on the less likely that the dealer will do anything for you. Good luck.

THANKS for your input but the dealer has told me that they just cannot do that ,that GM has to step in and resolve the issue. The reginal service manager called today and stated that my issue was the only one of it's kind. so we got on a three way line with my service manager here and he informed the regional manager that there were others surfacing. Now I'm in a wait and see what GM has to declare.

any 08 canyon owners out there that have any eng problems if so what type. this one i've got looks as if i'll be going thru the same issues as i did when my envoy had to be bought back . If so i will not be buying any more GM products. I just want to be treated like we the customer have a valid issue and not some jerk trying to get something for NOTHING. thats how they make you feel anyone else feel the same?

2004 colorado engine issue by lift4041

I have owned my colorado for about a year and half now. I have had various problems. Such as it acts as if its running out of gas, and pressing the throttle just makes it worse. I have to shut it off and then restart it, then it runs fine. Wierd? I used to have the check engine light coming on quite regular, but haven't had it on for some time now. But I do have an engine rattle upon start up. As well as clattering coming from the valves or valve train. I have received a letter from GM stating that there is a problem with the cylinder heads on the L4 and L5 engines. The last time I went to the dealer they said that the problems that I am experiencing are not connected with the GM issue. I will be going back since my engine noises are worse. Hope I don't run into a problem with them since my check engine light hasn't been coming on.
