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.

The local dealer printed out the Brake TSB, all 20 pages of it that go into a lot of procedural issues wrt how to turn rotors, how to clean rotors, et all. It did say proper torqueing of wheels (via torque sticks) and proper runout were absolutely critical with these brakes - any small deviation would result in pulsation within 4K miles or so.
 
What it did not mention were any replacement rotor parts to address the problem. So I guess the rotors, at least to date, will remain relatively flimsy and easy to warp.
 
Local dealer also printed out hot starting problem TSB. The report hints that the problem might be related to a Delphi EGR valve (saying that the vehicles with Siemens EGR valves already had newest calibrations). I'm to go into dealer tomorrow to see if they will recalibrate my '04 Maxx and if they do it, whether or not it helps.

I found old notes that complaint I had heard about was really specific to a 2006 model but am still checking on it.

THANKS again! It has been real cold, and I have not used the remote start. I have been manually going out and starting the car in the morning. The oil has dropped 10% in the last week and a half, and I have put over 1000 miles on. So it is acting normal now. I am going to try to start it tomorrow with the remote and see if that makes it drop. I have a suspension that it will.
