I got the latest TSB (002H)from the free www.alldata.com/tsb site, but that site no longer lists TSB issued prior to July 2006. GM updates this TSB in June each year to add new model year. I also, get my TSB from www.infotraxx.com. For 14.95 you can access all the TSB for your car for one year. They are in PDF format and you can save them to your computer for future reference. They currently only have TSB issued through May 2006. They add new ones a couple times a year. The latest one they have is 002F from June 2005 (when they added 2006 GM models).

What model year and engine (likely 3.5L) do you have? If you noticed this on a specific ignition cycle had you recently done a remote start or had a short engine run cycle before driving it when this happens?

I have the 3.5l, 2005 Maxx, and did a remote start (after market remote starter) - the car ran for about 5 minutes, engine temp a bit under the half mark. Never had a problem up until now. But, I rest the oil life monitor, and Since yesterday am (about 60 miles the oil life is down only 2% - it is now at 98%. I did a remote start this am - high 20's for the temp again, and knock on wood everything seemed normal. My oil life did not drop any on my way to work - about 10 miles. Yesterday it dropped 5% in about 30 minutes. Thanks for any ideas!

OK, UPDATE: It was down in the 20's, heavy frost last night, warmed up the car for about 5 minutes before I left this am. Temp gauge goes to a little below the half mark (side not - this is where the temp goes even on an extended trip - we went on a 200+ mile trip this weekend and only dropped 2% in about 250 miles). I dropped 10% in less than an hour this am. RPM and mpg remains normal. So, question 1 - does this sound like a thermosat prob? and question 2 - Can the service dept. hook a scanner up and see if the thermostat is bad - even with a "warm" engine? THANKS for any tips!

Well, here is what is going on: Only on extreme cold mornings does the oil life drop. So, took it to the dealer, car is not throughing any codes, they have no idea what could cause this. They said all check out ok, did an oil change and they said oil looked good. I know something is up, as it is not normal to loose 10% of your oil life in less than an hour. ANY ideas? THANKS!

Curious if you did a remote start or some brief engine run prior to driving when you saw the % drop?
 
If so you might be dealing with a software issue.
 
To your knowledge has dealer recently updated software in engine controller? There is likely an update although it would have been done per a TSB to address a long crank condition and not your complaint. However it might also resolve your complaint. If I can find out more I will

Yes, I this has happened when I remote start. I do not know about any software flash, I did have the car in in August and they worked on the steering tsb. Maybe they did something to the software then? I have an aftermarket remote that the dealer installed when we bought our Maxx if that makes a difference. THANKS for the info! It gives me something to suggest to the dealer!

NP but they certainly aren't going to tie the oil life complaint to a PCM reflash from anything in a TSB.
 
This condition was probably always present, not due to anything they did - just takes certain conditions to show up.
 
What I was saying is there there is a potential that this might be cleared up with latest calibration.

OK, I have not remote started my car since last week, and all is well. So, I am going to try the remote start next week and see if the oil life drops. I suspect it will. If that is the case, then I must need to be reflashed?

I still don't know if latest calibration made any changes in that area - I will ask about it.
