    I have a 2004 I5 with auto trans. Lately when I start my truck in the morning the starter skips a little. I know it has some kind of system that all you have to do is turn the key to the start pos. and let up and it will start the truck. Has anyone noticed this with there truck?

    What rear vents are you talking about; the pressure relief valves in the doors?
  • pjjbmpjjbm Posts: 12
    I guess you call them pressure relief valves. On my extended cab 2005 Colorado, they are on the both side of the back of the cab. Whenever there is a slight bit of wind, the are flapping and making a lot of noise.

    I don't believe they are supposed to flap in the wind. No matter what we are talking about, I don't know of anything that is supposed to be loose like that. See if you can reach them and snap them in place or if a fastener is missing. I'd bet that's your problem.

    Those are part of the flow through ventalation. These came to be when the auto makers did away with the little vent windows. When running heat/vent/air there needs a way for the air in the cab to leave creating a flow. Hence these valves. All vehicles have them to an extent. Some vans you see louvers built into the back corners near the windows. But they shouldn't flap and make noise that bothers the people inside.

    I had a similar experience once several years ago, but fortunately the wheel didn't come off...I kept hearing an odd noise in one wheel, and I finally stopped a took off the center hubcap...all the lug nuts were loose, and one or two were actually off the wheel. I tightened them up, and then called the dealership to complain, but that was the extend of it.

    You're VERY lucky it was a rear wheel instead of the front!

    I just wonder what the dealership is going to do because this is totally their fault and now I WANT a whole new driveshaft, rear axle and brakes. I left a long skid mark in the cement on the 407!

    I think I would contact a lawyer too.

    OK, I own a 2005 Colorado with 43,000 kms om it, 25 days ago I took it to John Logan Chev Olds... to do some repairs. WELL, they rotated my tires and fixed my brakes.
    Yesterday my boyfriend and I are driving on the 407 doing 110km and we start swerving through all lanes of traffic then we hear a big bang and the truck drops. My speedometer is going up and down like crazy and I can't steer or brake! We drifted off the road and onto the left shoulder. I got out and look at the rear end of my truck, to my surprise.... my tire was GONE. all I saw was what was left of my breaks and there was brake fluid spewing out everywhere. The 407 patroller found my tire 500m away and the wheel lugs were still in the cover that goes on the front. SO, John Logan is now dead for their crappy service that they did on my truck that almost killed me.

    I have a 2004 4x4 with a I5 and auto trans. I have had the thing to go into four wheel drive buy it`s self 4 times. This always happends when I am turning in where there is a bump. Has anyone else had this problem?
  • mike2250mike2250 Posts: 29
    does anyone else have alot of racket from the tailgate when going over a bump. If so how did you correct it. It seems most often when there is less then a full tank of gas. thanks

    I just backed my 2004(Colorado 4X4 LS Crew Cab I5) into my driveway and it was almost like I was backing with the parking break on It even squealed the tires which I never do. It sounds like the same thing I guess but It is going to the shop in the morning. :lemon:
  • dmathews3dmathews3 Posts: 1,739
    sounds like you have it in 4 wheel drive. Check and PUSH the 2 wheel drive button, maybe it's stuck in 4 X 4
  • vferrarovferraro Posts: 1
    I have had this problem several times. Also happens when the truck is turned left sharply. Slips into 4 wheel drive. My dealer says it is called a phantom shift but GM has not issued a recall bulletin for this yet. I have had this happen at least 5-6 times with my 2004 4x4 I5 crew cab.

    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.
  • My brake light switch has gone out twice!!! 2004 Colorado

    I will never buy another GM product.

    brake light switch is a heck of a good reason for never buying a GM vehicle. Go buy a Toyota. Make that a Prius so you can pay out $5000 for a new video screen after warranty. Park it on a steep hill and it shuts down to be towed, spin the wheels in the snow and it again shuts down for a trip to the dealer. Try backing it up a hilly driveway. Can't be done. Buy one so I can see what you have to say about them. :P

    You mean they kept the same cheap interior plastics that made the previous models look so cheesy? This is not encouraging. I was hoping for a nice gutsy V6 engine, and a 5 or 6 speed manual availability in the crew cab, as well as a decent looking interior with cloth inserts on door panels.
