sarah, I'm hoping you can help me before I contact an attorney. I own a 2006 H3 w vin # with last 6 being 108901. This falls within the range with problems. However, nobody at gm customer service seems to know what I'm talking about. My vehicle is currently in pieces and has been diagnosed with failed valve seat #5 and they are waiting to proceed until this is resolved. Please contact me at 360 4344808. My name is Sunshine. You can also reach me at goldenshinercomcast.net. Thank you.

Good afternoon goldensun,
 
I found your Service Request and just wanted to find out some details if I could -
 
What dealership is your vehicle currently at?
Do you know the name of your Service Contract (extended warranty) company? I do not see a General Motors Protection Plan on your vehicle.
 
Kindest regards,
Sarah

#665 of 707 Almost 3K into Head #3 on '05 Colorado,Fingers crossed! by pianoman435

Aug 22, 2012 (9:36 pm)

I did my homework, on this site, I knew about the head issue & bought a used '05 with the 3.5 I5 with 95,000 miles on it that had the head replaced at 82,000. I had 101,900 on the odometer when my mechanic told me the miss wasn't a bad coil but was the 30lbs of compression in #3 cylinder . I took it to the dealer & $2900 later it didn't miss anymore & I had a 12 month 12000 mile warranty on ANOTHER GM head. I was very upset when I was told how much it would cost, I called the Chevrolet Service number & was told they would look into it. 24 hours later I was told they wouldn't cover a penny of it ! IF THE HEAD HAD FAILED PRIOR TO THE OFFICIAL 100,400 MILE MARK they might have done something but since, fool that I am, I waited another 1500 miles before allowing it to fail, it somehow became completely MY FAULT!!! The Chevrolet person nor the service people at the dealership were unable to explain this bit of GM logic to me.
The funny(read extremely sad)part of this is I was leaning toward a Nissan but decided on the Chevy because of the better milage! It's going to take a lot of really good milage to make up for $2900 that I WOULDN'T have had to spend on the Nissan! The other thing that really gripes me is I was for the bailout of GM & Chrysler!!!!!!!!

Good morning pianoman435,
 
We can understand that vehicle repairs can be frustrating - how is everything running now that the cylinder had has been replaced?

If you had bothered to READ my post you would know that the CYLINDER was NOT replaced, the head was for the SECOND TIME making this the 3rd head on that engine in 102000 miles.
The previous head was replaced for the same reason at the same dealer just a different valve seat/cylinder involved. Also the exhaust manifold/catalytic converter(a one piece unit, another bright idea from Chevrolet) were replaced due to a crack in the manifold!
The check engine light is still on all the time & I get intermittant signals that my gas cap is loose(it's not)the vacuum recovery system is faulty somewhere between the tank & the charcoal canister.
Other than that it is running fine but then it was prior to this happening & then it wasn't & $2900 later it was again! So not only are my fingers crossed but my toes & everything else!
The decision I have to make now is do I spend the money for an extended warranty or send it down the road before it costs me more?

I'm sorry that I misread your original post, pianoman453. Thank you for taking the time to clarify that for me. When you contacted Customer Service, were you issued a case number (71-**********)? Please forward that to us at socialmediagm.com (or the last 8 digits of your VIN) and we will look into this further.
 
Kind regards,

#670 of 707 05 canyon code p1133 by sportster911

Sep 20, 2012 (12:00 pm)

So, i have this recurring code. Bank 1, sensor 1 insufficient switching. So far this is what I have done to it to try to remedy the situation: (2) new oxygen sensors, new exhaust manifold, new feul pressure regulator, new intake air resonator box, new thermostat, exhaust cam position solenoid. When monitoring the front o2 sensor while driving, it switches fine at idle and very light throttle BUT if i accelerate and maintain speed above 1500rpms the o2 sensor stays in the .70-.80 range. I hope someone out there has had experience with this and can tell me what I might be doing wrong(?).

I'd like to hear from anybody with the 8 cylinder engine. Have you encountered any problems? Does the engine have the cylinder de-activation? What's your fuel mileage? Thank you.
