I have a 2005 4x4 I5 and have been experiencing what I thought was the Exhaust valve problem what other trucks have been experiencing. But what turns out the BUZZING and lifter knocking sound is #PIP3811 "Rattle Noise form bottom rear of engine at 2000-3000 RPM--KEYWORDS: accelerate bellhousing buzz clatter detonation end hot housing idle knock load lower ping shaft spark." Another words on rare occasions, a light detonation/rattle type noise may be experienced around 2000-3000 RPM under light load/acceleration with the engine at operating temperature. I can hear a light buzz sound when the engine is cold and I can hear a light knocking sound, like a lifter knocking at around 2000-3000 RPM only on acceleration in drive. CANNOT duplicate the sound when it is in neutral reving the engine to 2000-3000 RPM . The Dealer is aware of the Service Instruction "PIP3811" and a repair is being developed to address this noise; They have not yet found a cure to fix the problem.
As for the Service Bulletin #04-06-04-081C Exhaust Valve Springs, they said it only applies to the I4 engine not the I5. Can someone concur with that SB?
I hope this info can help out with anybody else experiencing this buzzing, vibration problem I now have 30,000 miles on my truck...

04 Chevy Colorado- engine will not start twice STRANGE

I have also have had this problem. It has happened to me twice aswell, about 4 months apart and it has not happend in the last 6 months now. When I called the 1-800 #, they asked me if my "passlock" was lit. and I said yes. What it sounds like is there is a glitch in the anti-theft system. Both times I had to wait approximate 15 minuits before I could get it to start. I followed the manual on resetting the anti-theft system, but after numerouse attemps it finally started. The dealer told me if there was an attempt to steal your car it takes 15 min. before it can reset itself or there is a glitch in your computer that operates the anti-theft system "passlock" I hope this helps because I am too conserned on how the dealer does businesss, but if you get it documented at the dealership that there was a problem, then there is history documented you can be covered by your warranty even after it expires. And maybe they get enough complaints the engineers can look into it. I now have 30,000 miles on my truck with no real concerns...yet! Hope this helps...

I came across this website that will help to see if a Service Bulletin applies to your truck or at least help in your diagnostics. www.ownersite.com I also came across the SB: "SERVICING THE IGNITION SWITCH AND/OR PASSLOCK SENSOR. *TT" That might help with our problem in the trouble of starting. I also at first thought it was my fuel pump or a clogged fuel filter, but that was not the case. Hope this helps. I have a 05 I-5 Colorado, which has 30,000.

Got a 2004 Canyon 5-cyl. w/ 41000 miles on it. The check engine light came on and it feels like it's running on 3 cylinders. Took it to the dealer and they said that there is a problem with the valves. The entire head and valves needed to be replaced at a cost of $3200. The warranty expired so basically I would have to pay for the repairs. However the service advisor told me that GM knew about the problem with the valves but didn't issue a recall (I guess because it would cost GM a bundle). I argued this point. Why should i pay if GM knew they had a faulty engine. The service advisor discussed it with the manager and they agreed to stand behind their product and pay for the repairs. I am supposed to get the car back this wednesday, so we'll see if they fixed the problem. I will not buy a GM product again. I bought an Envoy at the same time I bought this truck. I traded in the Envoy after so many problems came up from the CD player breaking to loose screws on the lights that i had to tighten myself. I have a Pilot in place of the Envoy. It's a world of difference when it comes to fit and finish between the honda and the GMC.

All vehicles have problems. Honda has had theirs too. Toyota is having big problems with the new Camry and is not standing behind them, putting off the customers and saying nothing is wrong. It is supposed to drive this way. I can remember Honda doing the same a few years back. At least the General stepped up to the plate. I had a Chevy Tracker that was almost 2 years out of warranty when I had shifter problems. They had to drop the tranny as it is mounted into the top of the trany. $400 just to drop it to see what was the matter. About $1600 later it was fixed. While it was down I called GM and explained that the vehicle though was out of warranty time wise it was still about 10,000 miles under warranty. I also told them it had had all maintainance, even stuff like drain and new fluid in tranny even though it wasn't ready and they covered all but $360. I was impressed. I bet a weeks pay none of the foreign makers would go that extra mile. Heck sometimes you can even get them to step up to the plate and fix what is wrong during warranty. Check here on the Camry 2007 forum and listen to them cry big tears.

Well the Canyon and the Envoy are the first GM cars I've ever purchased. I've only driven Honda's Acura's and BMW's. The Canyon and Envoy are the first cars I've had that have had problems before 130k miles. Service wise though the worst car company is Volkswagon. They are complete jerks to deal with when it comes to warranty repairs or any service for that matter. BMW is the greatest when it comes to service. They even give you a loaner car while your car gets serviced.

I have a 2004 Colorado 5-cyl. w/46000 miles, and am having the same problems you described. I was told yesterday that the head is on back order from GM, and is not expected until March 1st. Does this seem like a reasonable wait time? As you experienced, the cost is not coming out of my pockets, but the inconvience is. This is not my first GM product, but this is the first time I have had any problems like this. I will withhold final judgment until I see how the whole scenario play out.

My question is can you still drive the truck? If not did they give you a comparable vehicle? If it is driveable I wouldn't worry. If not and they gave me a small piece of crap to drive than I would be upset. It does seem a little long of a wait too. Have you called the GM line to see if they can hurry it up. Just be nice when you call.

I took my Canyon in Jan 11th i think. The service advisor said that he should be getting the head next week and the repairs should be complete Jan 28th. So if i do in fact get my truck back on time then your wait time of March 1st is ridiculous. My big question is did GM fix the problem and ship us a revised head or are they just going to send us an original head that I will have the same problem 10k miles down the road. I am betting on the latter happening that is why I will be trading in the truck once the repairs are done.

The truck is torn down for repair, the head is off so it is not driveable. The Chevy dealership doing the repair work does not have loaners, and the dealership where I bought the truck, not a GM dealership, is helping a little.
I called GM customer service, with no luck. GM politly said they could not help because the dealership is not GM.
Do you, or anyone have a better number for GM? It would be nice to know when the head is being shipped. Also, if they are shipping a new head, or just replacing selected parts.
