Cooter bfd. Apparently only those with instant notification got to see part of your post that now seems to be removed.
The smells have been since new and prompted me to try recirculate which does not seem to make a difference. The odors are from different sources, away from vehicle, such as passing downwind of a papermill or sewage processing plant. Most I don't know the source but found them undesireable.
I even suspected they may have forgotten to put the filter in at the plant but wanted to know just how the filter was supposed to work before removing glovebox to check. Some filters only remove particles, odors being too small. I learned from the ACDelco site that they do "filter out molds, pollen, allergens, smoke, fumes, and odors". So something definitely seems to be wrong.
The odor thing, I asked about at dealer and was told it depended upon whether it was a carbon filter. That was before I found the ACDelco site.
I've had CAF before in Fords and they worked extremely well. One in particular which was $100 for replacement. It had no paper whatsoever. The media was a mat of fiberglass long fibers heatset in place with carbon impregnated. Overlooked it had become totally clogged with dirt and road grime, I'm talking layers of caked on. Soaking with oven cleaner it rinsed clean like a brand new filter and worked perfectly fine afterwards. This AC one is far cheaper but have no understanding of why.
Has anyone else noticed odors entering?
Sevice suggested it might be from an air leak, but I have not noticed any.

Well, the good folks here don't seem to have a juvenile sense of humor. I wondered aloud if that maliferous(???sp) odor may have eminated from your hind quarters (yes, I used the "A" word)
In all seriousness, depending on the smell, it could be a number of things. I had stated that a sulfur (rotten eggs) smell could be an overcharging battery, or that had something been inadvertently been kicked under a seat or floor mat, that could be a cause. Also, formaldehyde is used in the mfr of some of the components too. If it is a musty type smell, that could be from a water leak of some sort. If it is continuous, than that should rule out another car. Other obvious scents would be antifreeze, gas, oil, etc.
#61 of 87 Seat Memory dangerous
Dec 03, 2010 (1:28 pm)
My wife drove my car for the first time today. She is quite short and adjusted the seat as she needed. She had her own FOB because mine was in my pocket all day. I later drove it and hopped in quickly because of the seat moving as soon as door is opened. It was trying to put my knees into the dash before I realized it was trying to adjust for her and mangaged to stop it by hitting one of the memory buttons on side of seat.
What a messed up system, mine is.
She later drove it with her FOB again and this time the seat did not move at all when she got in.

Update. Vehicle in for memory issues.
I see they noted that it is supposed to go to last used position. Their response is comedic. "Vehicle must be in park for memory to function."
OK, is anyone not putting their vehicle in park before shutting down? Upon picking up vehicle the seat again went to what was the position for FOB when I first got it. And sometimes it goes to where I actually set it.
At least, I'm guessing I will have to go over it with tech and maybe fixing this one issue will fix the rest of the memory issues.

It always is in park before shutting. You might need an adjuster memory module.
I have commented on my memory seat problems before, which are relatively minor compared to some. These are apart form the 'bass ackward' programming which recalls the memory position upon 'door open' vs 'door close' or 'ignition start'. My dealer says this programming cannot be altered. At this point, I can get in before it moves much .
Again, my config is for easy exit, memory recall and passive entry. When I use the FOB unlock, 100% of the time, the seat goes to back to or very close to my last setting. Sometimes, I check after I'm in and push seat button 1 and it may move a fraction of an inch. This is not too bothersome.
What does bother me is on passive entry, the seat moves to a strange low and far back position. This was on my list when I got the 'clang' issue taken care of last week. I mentioned the PI0187 issue noted here and on another forum . Apparently, this is a fault. They reported on my invoice "document 2542475, ordered seat module". I'll report back when it comes in and is installed.

We seem to be using the seat memory in the same fashion. When using passive entry I sometimes get the position you mention. Other times it actually goes to correct point. At the very least this points to a bug in the computer.
Since getting back, I discovered it is possible to shutdown engine without being in park and not sure why you'd want to unless towing vehicle.
Also, I forget the exact actions at this moment, but I've had it retract more than one time without going forward. (Not sure I may have halted forward motion) This gets the seat back much farther and seems to make exit and entry easier. I have to wonder how it determines the correct stops and if it is possible to program it to retract more normally.
There is some rather "stupid" funtioning and allowance of functioning. If it is impossible to have the computer wait for a weight on seat or ignition switch change of state, I'd think they could at least insert pause into movement forward. Or even change the state of door for going forward. Wait for door closed signal, or even door locked, such as hitting lock control on dash console.
This BS is unaccemptable.
I've seen ads for the new Lincoln and its mention of Nav system with Sync. I noticed that there is a four way switch on steering wheel, maybe even 5 way by pressing after scrolling to the wanted point. And it seems I heard Sync has thousands of voice commands. Certainly GM could have done far better than this.
As to not altering program, I sniff some BS. They also told me that about the headrests and it took me about an hour to figure it out. I suspect they do nothing unless GM tells them to, so as to avoid any liability.

Elsewhere, someone mentioned using a 'delay' action in opening when using passive entry, i.e., pull open part way and then complete the action. This supposedly allows the memory recall to work better. I tried this and it improved it on a few tries. But, it didn't work 100%. This 'delay' issue also was noticed before. It came about sometimes when spouse tries to get in passenger side when I know the car is unlocked and I had passive set for all doors to open. I then changed it to 'driver' only for more secure entry as I had to go into the city a few times. Now, I reconfig'd for all doors so will see if this approach improves passenger side unlock.
I did test drive a Lincoln MKZ standard 6 but didn't like the ride-too harsh on streets with imperfections- compared to LaCrosse. While I tried the Nav, I didn't play around with voice commands. Not too sure if 'thousands of commands' makes it easier-I have trouble remembering the few for the Buick and need to check the manual or the 'help' once in a while. What is needed and within the capabilities of PCs now is true 'voice recognition'.
BTW, what did you do on the seat had rests, reverse them? I finally found a position that works for me with the stock location of the rests, slightly more reclined than on previous cars.

Upon returning to Savannah, we got that horrible smell of paper mill entering vehicle again. Passengers commented about it thinking it was of the type you insinuated only to realize quite quickly it was too chemically smelley. The system is definitely not doing its job of removing odors. Also the quirky part of maintaining temp constant showed up. My son-in-law noticed the sudden blast of cold air when it wondered in that direction. Having to change the setting by as much as 10 degrees to maintain comfort after the vehicle is thoroughly warmed is just wrong.

".....Passengers commented about it thinking it was of the type you insinuated only to realize quite quickly it was too chemically smelley."
This, coupled with the engine idling, and the poor FE keep leading me back to the Cat. A malfunctioning cat will give you poor FE, rough running and a bad odor (rotten eggs).
