Purchased a new 2021 Limited about a year ago (during the pandemic). - I love it.
I am retired, so coupled with pandemic, I have only driven the Crosstrek 4700 miles (in 1 year).
(As an aside, I had the oil changed at 1,800 miles and recent tire rotation).

Yesterday I took the car in for yearly State inspection, as required. Passed - of course.

But the multi-point inspection revealed that the battery is cranking at 301 when it should be at 620.
Car is alway garaged.
I am concerned about getting stranded this winter.

What steps/actions do you all suggest I take - car is still under warranty.

Thanking in advance!!!

There are lots of battery threads here. Try the search. General consensus seems to be that the OEM battery is not up to the job. We had issues and I replaced it with an Odyssey and it's been fine since.

Go to your dealership, and have them replace it immediately. This should not be an issue.

It would be covered under warranty, I just wanted a better battery than the OEM.

I believe I will contact the dealership and see what they have to say and what they might suggest. Do you think that the lack of driving on a regular basis contributed to this, or might it be all the extra electronic components that are now on the new cars (I have had so many many cars and never had an issue with shortened battery life).

I've noticed with ours by checking the voltage regularly that the car doesn't keep the battery charged up much, especially with infrequent short runs. And leaving it for extended periods at a low state of charge is not good for lead acid batteries. The Odyssey is an AGM and takes up charge faster, and also is more tolerant of abuse.

you're not driving enough and your new battery may also die a slow death. get one of these.....

Amazon.com: NOCO GENIUS1, 1-Amp Fully-Automatic Smart Charger, 6V and 12V Battery Charger, Battery Maintainer, Trickle Charger, and Battery Desulfator with Temperature Compensation : Automotive

I'm sure that the fuel pump running sometimes when the car is parked doesn't help if you don't drive regularly. I often go a week without driving the car, but when I drive, it's usually over a half hour at a time, so the battery gets charged fully. I haven't had any battery problems so far - owned for 20 months and 12K miles.

The evap system is a mere blip. I know because I have a BT battery monitor (thanks @rp). I'll post some charts if you like.

Is that what that buzzing is? I do hear it running for a considerable amount of time. What exactly is it doing?

BTW, could you provide a link to that Odyssey AGM battery you bought for your Crosstrek? I may eventually go that way since I often travel to very cold places in winter where it isn't unusual for temps to go down to the -10F to -20F range.

Noise from under the vehicle
S00AK01
NOTE
You may hear a noise from under the
vehicle approximately 5 to 10 hours
after the ignition switch is turned to the
“LOCK”/“OFF” position. However, this
does not indicate a malfunction. This
noise is caused by the operation of the
fuel evaporation leakage checking sys-
tem and the operation is normal. The
noise will stop after approximately 15
minutes.

Was it a Subaru dealer that did your state inspection, and multi-point inspection? If an indy, then take it to your Subaru dealer and have it checked out, as recommended in several replies above. You may be surprised to hear that your battery is just fine. Separately, you would most likely notice poor battery performance when cranking on a day to day basis. Did you notice anything atypical yourself prior to the multipoint inspection? It might also be a good idea to invest in a Noco GB40 or GBX45. These are compact boosters, that can help if you get stranded due to an undercharged battery.

Ok, thanks for the update. You are covered either way. Noco also makes good battery chargers. If you park in a garage, you could consider putting the battery on a charger once a month or so. I have their 10 amp charger and boosters GB40 and GBX45. I typically top charge the battery during oil changes.

UPDATE
Took the Ctrek back to the dealer where I purchased it and showed the printout from my inspection. Service guy stated he would check it out - preform a battery test and if low might recharge it (which would take about an hour).
He returned in a bit and stated the battery was not sufficient and failed to meed industry standards. Thus they replaced the battery.
Happy with the outcome - not so happy that battery failed so quickly. Tech suggested that I drive the car more often, which I will try to do (as I do love the way it handles/drives).

Were you able to get the Odyssey Extreme version? From what I can see, their Performance version is the only one that fits our car.

Any AGM will be better than the OEM battery...
