It's difficult to advise some next steps for you at this point. As a dealership will likely charge you a diagnostic fee, I would recommend that if you had considered visiting them to wait until this concern occurs consistently (as you say that right now the oil pressure problem has been resolved ant the engine noise is gone). If you're going to pay a diagnostic fee, I want to make sure that you are able to get some results from the visit instead of them saying that they're unable to diagnose anything.
For the 2006 model year, the powertrain warranty had not come into effect for GMC vehicles, unfortunately, which I realize is an important factor for many as well.
I know that this suggestion may not leave you with the most peace of mind as I can tell that you are interested in resolving this before it escalates. I see that you used kilometers as a unit of measure, and am guessing that you are a resident of Canada. Have you worked with GM of Canada before? They can be reached at 800-263-3777, and while like me the representatives on the phone don't have technical expertise they can assist you in the process of working with our dealerships.
I wish I could do more, but hopefully this has helped in some way,

The problem reoccured within 5 mins of driving time this morning. I'm very reluctant to go to a dealership. In my past experince, the troubleshooting includes too many aspects of a marketing plan.
I'll have to try research the problem more.
Thanks for your reply.

I'd like to say that I'm sure there are at least a dozen different problems that all appear to be the same when reading all these complaints. My promlem was that the previous owner of my vehicle followed poor maintenance practices and used inferior parts. This "common" problem was not GM's fault.
As I said in an earlier post, I had just purchased my 06 Envoy Denali, the next day got the "low oil pressure, turn engine off" message and was horrified when I googled if and heard of all the problems.
I did hours and hours of research and finally decided to do an engine flush (which should not be part of routine maintenance) changed the oil twice that day and installed a premium oil filter. Just in case, I replaced the oil pressure switch and also had the oil pressure tested at the filter to be sure the oil pump was okay. A 1000 miles from now, I'm going to change the oil again and install another premium oil filter to make sure the debris from the engine flush is completely gone.
If I can offer advice to other people with similar problems, don't trust that the discount oil change people are protecting your investment even if they charge you a lot of money and make you feel that you are doing the right thing. I'm not a fan of dealers but they will at least install the recommenfed part for your vehicle your best bet always, is to have a mechanic that you trust.

hey "kpick", sorry to be the bearer of bad news but... my '04 garage kept, low mileage envoy started with oil pressure gauge going to full max on wet days. it now works when it wants, but the speedo is pegged at 130 mph, that used to only happen when wet, but it has not moved in 2 months... i took truck in to GMC dealership, and they say "you need a whole new gauge cluster" about $600. and no, they would'nt even split the parts with me !!! the service writer even said "this is a huge problem with the envoy line, be thankfull its only speedo and oil pressure" thats not working !!! it plain sucks that they wont do a recall.. if any lawyers read this thread, a class action suit would have tons of people to join..... its too bad cuz i always bought american.. no more.

I am 100% with you. Are there any Attorneys in this forum or does anyone know of any that will look into C/A suit for us? If so let the forum know and he will have a ton of backers.

Did you ever get your problem fixed? I had a similar problem with my 2003 GMC yukon SLT. I may have a solution for you.

Sorry to hear that! I thought you were dealing with a faulty instrument cluster. i had mine replaced for a fraction of the dealer cost.
