    I suggest you get it to your Dealer right away.You may want to take a look at this forum and see others with the same issues and the process they are going through...me included.

    Get it to your dealer- asap. Refer them to bulletin #PIP4716a. This bulletin specifically discusses this noise and that the very LEAST they should do is replace the "cam phase actuators"...it also goes on to say they should also check the cam phase actuators AND the solenoids for debris, and also check the solenoids for loose or torn screens. IF debris is found, they are required to change oil and filer, covered by warranty. However, if debris is not found, they are not required to do so. In my case, no debris was found, they replaced the cam phase actuators and said that it was caused by an electrical failure since they found no debris in the oil.

    Others that have had only the cam phase actuators replaced with no oil change have had the noise start again after a few days or few hundred miles. MY reccomendation (also what I did)- if they decide they don't need to change your oil, have it changed anyways! Make sure to use 5w30 that is "dexos" approved. I used Mobil 1 synthetic 5w30. It has been almost a week since the repair has been done and oil/filter has been changed, and so far, so good. No scary noise on start-up and mileage has returned to normal.

    Since it is a random occurence, not every time, the BIGGEST thing you can do to help your case is to catch the noise on video! Record it with your phone. The dealer had my car for 4 days, heard the noise once but only one guy heard it and they didn't know where to start looking and couldn't replicate it again. I recorded it on my phone and took it back a few days later, they listened to the recording and acknowledged that it was, in fact, a bad noise. (DUH!)

    Good luck! Be politely persistent! MAKE SURE you ask if they check the solenoids for debris, etc., as the bulletin states. My dealership didn't do this until I asked, I had to ask about every step of the bulletin for them to even COMPLETE the full work. Hold them to every word of the bulletin (google PIP4716a to find a copy)!

    Is there any place to look up this bulletin and get the printout? I looked online and couldn't find it.

    I think I heard this noise in my week old Equinox (200 miles).

    ---------------------------------------------------------------------------------
    This PI was superseded to update models, years. Please discard PIP4716.
    ---------------------------------------------------------------------------------

    The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

    Condition/Concern:
    In rare instances a technician may comment they hear a short, sharp rattle noise from the front of the engine on start up.

    Recommendation/Instructions:
    If the noise is from the front accessory drive area, inspect the engine belt. We have seen concerns with engine belts causing a loud ticking type noise. If found, verify power steering pulley outer edge is aligned flush with shaft and repair as needed. If pulley alignment is correct replace the engine belt.

    If the noise is still present and is very short and sharp in duration (2-5 seconds). This may be an issue with the cam phasers not parking properly. Once the noise is verified as the phasers, they must be replaced. If the cam phasers are replaced, remove the CMP actuator solenoids to inspect for debris. If debris is found clean and inspect for torn or loose screens and replace if necessary.

    Note: If debris is found in the solenoids and phasers change the oil and filter before returning to service, in some instances it may be necessary to change the oil/filter multiple times with a test drivein between each. The filter and solenoids can be inspected afterwards to ensure no additional debris is present.

    Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

    GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION

    Also, so you HEAR a confirmed example, there are at least two videos on YouTube of the noise (one is from me). On YouTube, search "equinox noise start-up" and you should be able to find them.

    Good luck!!

    Made an appointment for the 2.5 engine start up noise, the talk of this town. I showed the Service Manager the Service Bulletin and he smiled shrugged his shoulders and said, "Wow never heard of that problem". That was that! I had my oil changed at 1350 miles and the car of course did not make the noise when started. It seems that the head in the sand attitude is the order of the day. I will monitor my vehicle and keep track of any further noises. At least I took the only measure I knew of to prevent any future issues, IF the oil change has any impact.

    From what I've read, oil changes DO make a difference, but it also depeds on how bad yours is so far. If your mpg is significantly reduced, and you hear the noise again, I'd take it in. And get it recorded if you can. Whatever happens, just make sure they make a note of it for warranty's sake.

    Thanks islaguy. I noticed you said the old PIP code should be discarded. What is the new one?

    Caron,
    I picked up my Terrain yesterday 6-15-11 after it being at the Dealers for 8 days concerning this startup issue.The first repair work was done 5-23,24,25,26 and 27 2011.On the third start after these repairs the same exact racket was back!This is now twice with the same issue and no positive results .I have been living with this for over a month now.It seems to me that nobody knows what the cause or fix is after all of this time.So this will be my third time back with NO results!
  • I have a claim into GM but they are unable to help me. Does anyone know who I can call to help me with an accident due to problems with my transmission? Thank you.

    Hey, I know in Texas the lemon law is 3 failed repairs for the same problem. This time when you take it in, tell them they are dancing the fine line of having to go through a lemon case.

    islaguy,

    I would like to set up a case with GM Customer Assistance. In order to start the process I will need your complete contact information (including full name, mailing address and phone number), VIN, current mileage and the involved dealership sent to me in an email. Also, could you please provide a brief description of the problems you are experiencing?

    Thank you,

    I have a 2011 Equinox LS that I bought in January. It stalled a few weeks ago, so I took it in for that to be fixed along with a laundry list of other issues that I have had. The mechanic addressed four different codes that popped up and some of the problems have gone away. However, the car makes a terrible grinding noise on a cold start. He was unable to duplicate. In addition, when I come to a stop, the car rocks back and forth at least 5 or 6 times. This can not be normal. Does anyone else have this issue? Wait...there is more. When driving with the A/C on, I get a loud hissing noise that occurs about every 10 seconds. The mechanic claimed that it was normal. Well, I have a co-worker that drives the exact same model. This noise is definitely not normal. Also, I occasionally get a drumming noise from underneath the car when I stop. It is a rhythmic thumping that starts off slow, then becomes more rapid before suddenly stopping after about 15 seconds. By the way, my car has 3,500 miles. Thanks GM. If anyone has had a similar experience with any of the above issues, please let me know. Thanks so much.

    I have a 2010 Equinox 1LT and I have the exact same "drumming" noise. If I stop for about 10-15 seconds I start to hear a thumping noise...just like you describe. If I slowly creep forward...it goes away....when I stop again...it comes back. It does not matter if it is cold, hot, A/C on or off. I mentioned this to my dealership several times and the can not find anything. They tell me that it might just be body flexing....

    I checked and there is no fluid leaking. Just a weird thump noise.

    I have the grind on a cold startup...the car almost feels like it is back-firing. I was told this was normal.

    I don't get a hissing with my A/C...but it seems to shut on and off every 10-15 seconds.

    Nice to know that I'm not going insane...
