Just received this email:

Dear Subaru Owner:

We would like to thank you for your selection of a Subaru vehicle. At Subaru, we take pride in our products and are committed to your continued satisfaction.

Subaru has developed a modification to the Engine Control Module software logic to improve the monitoring parameters within the On-Board Diagnostic (OBDll) system for the engine coolant thermostat. This correction ensures that should there be an abnormal condition (i.e., the engine coolant does not reach or maintain the proper operating temperature), the “check engine light” will illuminate. The proper illumination of the “check engine light” is needed to alert you that corrective action may be required.

This software change has no effect on fuel economy or vehicle performance.

WHAT WE ARE ASKING YOU TO DO PROMPTLY

We ask that you schedule an appointment with your Subaru Dealer as soon as possible to have your vehicle’s Engine Control Module software reprogrammed. This will take approximately 30 minutes to complete. However, it may be necessary for you to leave your car longer on the day of your appointment to allow your dealer flexibility in scheduling. Your Subaru dealer will perform this modification at no cost to you.

CALIFORNIA REGISTERED OWNERS

The California Air Resources Board requires that emission related campaigns be completed prior to California’s vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your next annual registration. Upon completion of this campaign, your California dealer will complete and provide you a “Proof of Correction Certificate.” If required, present the certificate to the California Department of Motor Vehicles (the “DMV”) when renewing your California registration as proof of campaign completion. If the DMV does not request the certificate, we recommend that you keep it for your records.

In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the service we are providing at no charge, your vehicle may not pass this test.

I'll probably have this done BUT this could be a case of:

"If its not broke don't fix it!"

This update will only create a new situation where the check enine light will illuminate. It makes no change that will result in better performance or drivability like reducing the high rpm's at start up.

I suspect, IMHO, that the reason SOA is doing this is because of the CA emission test as stated in the email. If it wasn't a case of failing the CA emission test because the OBDII can't report this problem then we'd probably never hear about this. I assume the reason for this update is that in case the themostat sticks in the open position then the engine wouldn't reach normal operating condidtions resulting in a rich fuel mixture and excessive emissions.

I have a seperate coolant temp gague so I would be able to tell if the temp is not getting up to normal - which seems to be between 192 and 198 F.

Like I said, I'll probably have it done but don't see a great need for this update. I just may wait until I need something else done.

On Thursday I received the same letter informing me about the reprogramming for my 2011 2.5i premium. What irks me is that I was at the Subaru dealership 2 days before I got that letter for an oil change and no one mentioned it. Wouldn't they have known about it then?

I got mine in snail mail yesterday. I know they have my email address, wonder why it wasn't sent that way?

Mine goes in for other service in 2 weeks, it can wait until then.

I haven't received anything yet. I get plenty of e-mails and am enrolled in my.subaru.com. Just checked the website and nothing on there either.

Is this a PZEV only thing?

It's for vehicles registered in CA, CT, MA, MD, ME, NJ, NY, OR, PA, RI, VT and WA. I THINK those are the PZEV-required states, I'm pretty sure NY is a PZEV-required state.

That particular monitoring has been in place since at least ODBII days. Roughly if the engine coolant temp doesn't climb above 150F within some time after startup it's supposed to throw a code something about engine coolant temp insufficient for closed loop operation. It sounds to me like it is already required for emissions but the programming is screwed up so now they have to fix it.

Anyone who has had this done - do the user settings have to be redone after the reprogramming by the dealer - like the seat belt chime adjustment and/or the fuel mpg calculator/teperature/clock adjustment? I would assume they would - thus another reason not to have this done unless you live in CA.

I had mine done - took about an hour and did not have to reset anything when they were finished.

Just had mine done. Now when I come to a stop light something buzzes like my cell phone and its not my phone. Also I notice the idle change when stopped, almost like it was going to shut off, then kicks back in. None if these had ever happened prior to the re-call fix. Anyone else notice anything like this???

Had it done last Friday. No changes, everything 100% perfect as usual......except for that click in the shifter area that I think is the reverse lock-out......."operating normally", but noted. 3.6 engine.......

Has anyone who has had this Service Program completed seen a drop in their MPG's?
Prior to having this done, my on board "AVG MPG" indicator (I know these aren't all THAT accurate) normally showed about 25.8 (or better) MPG for my normal around town driving here in Southern Oregon (mostly rural, non-freeway driving).
Since I had this (WQC-39) completed, the "AVG MPG" indicator seems to be STUCK on 24.3... ??? :8:

Yes, My wifes 2011 OB got way better mileage before the reprogramming. I thought it was just her getting on the gas but something has changed. I'm going to talk to my dealer about it. Let me know what you find out

I had an MPG hit as well, but we also switched to winter tires, driving in snow, winter gas. I'm not sure we can say it was the update.

However, I have a conspiracy theory I'm working on: Subaru delivers new OB's with ECU software that's tweaked for MPG's at the expense of drivability. After a year or so, they issue an ECU patch along with some other update that secretly fixes the drivability at the expense of MPG's.

This keeps the EPA and new owners happy, as more cars will get close to the advertised MPG's out of the gate, but later on they can issue fixes that they know will harm MPG's, and hide behind the cover provided by the necessary repair, and MPG's just have to suffer. After a year, owners like me will just keep the car without complaining; it is what it is.

This seems to explain my experience, and from what I read, similar updates were issued after the 2010 first came out. In the end, though, I have no proof the MPG's are down for any reason other than I stated above.
