funny- I have the same problem on 05 llbean. My dealer suggested to change the catalytic converters after seeing a 420 error code. What error code do you have? You can get it checked at a Autozone for free. I had the CEL & cruise light flashing on a misfire before.
you can check this sticky for the OBD codes.

ask them for the DTC (the stored code or codes that they scanned) and post them here.

what city are you in and how old is your battery?

perfectly normal for a CEL to be accompanied by a disabled cruise and other systems nowadays. The car's computer will always do that. doesn't mean the cruise control is involved at all.

Thanks and I'll ask for the code when they call me again. I live in Minneapolis and the battery is as old as the car (6 yrs).

Yeah, you're probably due for a new battery.

Which dealer are you at?

The car is at White Bear Subaru dealer. I've been happy with them for most of the visits

OK, dealer called again and nothing was found/done. I did get the code and it is P0016. Any idea what the error code is about?

I did check the code list thread and P0016 is not in. I'll try some other search and see what I can find. Let me know if anyone knows about the code.

I don't see P0016 in the service manuals I have. Strange. Are you sure the dealer gave you this, or can you confirm it with the dealer? Or bring the car to Autozone or one of the other major parts stores that will read the code, often for free. Just get the code read and repost here.

(It's a 2006 LLBean which has the 6 cylinder engine and 5-speed automatic transmission.)

Other than the CEL and flashing cruise control lights, are there any other symptoms, such as engine misfiring, unable to start the engine, or it stalls, or no acceleration, etc?

brief search yields hits for cranshaft position sensor, or crank/camshaft postion sensor disagreement ???

I would clear the code, montor how soon it or other codes return.

I'd consider a weak battery 'could' cause spurious codes to set. It has happened to me. So, perhaps have the battery tested. (if you do need a replacement, I like the top-of-the-line O'reilly, but it's your choice, could weather needs are different than ours down here.)

how many miles on the car? any other oddities? (noises, electrical problems, wrecks, modifications, recent repairs, etc.?)

Thanks to everyone for your suggestions and help.

The car is getting close to 60K miles. So far there hasn't been any noticeable issues other than the following:
1. Check engine light and cruise light as mentioned here
2. Higher/rougher engine noise when driving about a month ago. Dealer did an oil change and was good since then. I had been doing oil change myself before this last one. I was using 5W-30 Pennoil and Subaru blue filter. I got Subaru synthetic 5W-30 stocked up for future oil change.
