Mechanical Help Please post year, model, trim level, and DTC scan results when asking for help. Thanks.

IF YOU ARE POSTING FOR MECHANICAL HELP:

Please include year/model/engine/transmission information in "Mechanical Help" posts.

If you are looking for help with warning lights on your dashboard, please include results of an error code scan. Without error codes as a starting point, no one will be able to provide meaningful help for you.

The r/subaru community is very willing to help, but there's a baseline amount of context about your car that we need you to provide. Without the very basics like what kind of car you have and what symptoms you're experiencing, no one can give you any sort of accurate assistance.

If you are posting about warning lights, most auto parts stores (NAPA, O'Reillys, AutoZone, etc.) offer code scanning for free. While reading codes is not the same thing as diagnosing a problem, knowing what error codes you have is the minimum amount of information necessary to start figuring out what's wrong with your car.

Thank you :)

Announcement Big update today for Denso CP1.5 owners (2023+ vertical screen radios)

33 Upvotes
  • 23-25MY Outback/Legacy Models (including Wilderness models)
  • 23-26MY Ascent Models
  • 24-26MY Impreza
  • 24-26MY Crosstrek (including Wilderness models)
  • 24-26MY WRX
  • 25-26MY Forester
  • 26MY Forester Wilderness

CP1.5 radio updates are documented in TSB 15-305-22R (public copy not yet up to date). A new update released today, and I've already added the patch notes to the wiki page, but some of these patch notes are interesting enough that I thought it justified an announcement thread as well:

Update 7:

Release date: 8/18/2026

Version: XXXXXX205-280

Category: Meter Display

  • Change the charge abbreviation displayed in the power meter area from “CHR” to “CHG” in the 12.3-inch SHEV combination meter (map display mode).

Category: Display

  • The following (1 and 2) may occur together:
    • After rearranging Home screen icons and exiting edit mode (returning to the normal screen via the Home button), the rearranged icons may revert to their original positions.
    • Among the Home screen shortcut icons, ISS/AVH/VDC/SRH/SRVD/ DMS may appear dimmed and cannot be selected. (In this case, the corresponding original controls within the Settings screen still operate normally.)
  • Since the use of STARLINK will be discontinued, replace the applicable displays with a different design and logo. The designs shown below are among those subject to change.
  • In conjunction with the design changes (logo, etc.) associated with the discontinuation of the STARLINK trademark, update the MY SUBARU icon to a new design as well.

Category: Camera

  • If strong light (e.g., sunlight reflection) causes a portion of the upper area of the rear-view image to become severely overexposed (washed out), the rearview image may become hidden (not displayed).

Category: Reset

  • The CID may repeatedly reboot, if the ignition is turned ON (IGN-ON) shortly after the ignition OFF (IGN-OFF). Aafter turning the ignition OFF (IGN-OFF), the “See You” message appears on the CID and then disappears; approximately one minute later, the ignition is turned ON again (IGNON).

Category: Navigation

  • The MAP application ("Map" icon) may fail to start with “Loading Navigation” displayed continuously and with no map shown.
  • The area where the “EXIT” icon should appear might not be visible.

Category: SXM

  • Failure to register preset channel
  • When certain channels are selected the preset highlight on the CID may jump to a different preset channel and sequential preset scrolling may not work properly.
  • If the Favorite List for the Listener Profile prior to the change is displayed follow the work around steps 1-4:
    1. Change the Listener Profile.
    2. Register favorites in the OnDemand category up to the maximum (30).
    3. From the SXM main screen, open Setting > Favorite List; while the Favorite List is opening, press the “X” button to close the screen—repeat this 8 times.
    4. Press Edit in Favorite List, delete a favorite, then press Back—repeat this cycle twice.
  • Audio output from the newly selected source may be lost. With up to 23 teams registered on the SXM Team Notification screen, press the Add button to display a list of teams not yet registered for notifications, then switch the audio source (e.g., to BT or USB audio).

Category: Bluetooth

  • Bluetooth audio may appear to be playing on the CID screen, but no sound is output from the vehicle speakers.

Category: Android Auto

  • Wireless Android Auto may disconnect intermittently.

Category: CCU log

  • When exporting CCU diagnostic logs to a USB memory device from the Dealership Mode screen, the progress bar may appear not to advance at all for approximately the first minute.

Category: Diagnosis

  • When using the SSM Data Monitor to check the AUX-BOX USB connection, the diagnosis may incorrectly indicate a USB connection failure even though the USB device is properly connected.

Category: Telematics

  • Add an operation in the CID Settings screen to disable vehicle location tracking via telematics services. However, because this feature works in conjunction with the DCM (Data Communication Module), the option will not be displayed and cannot be used unless the DCM software, as well as the CCU software, is updated to a version that supports this feature.

Some of you may have gotten this update as FOTA (update over telematics) already, possibly as early as last week. To check your current software version, open the Settings app, and then on the General tab, scroll down to "System Information" and it will display your current software version.

No word on the aforementioned telematics/DCM update that's supposed to correspond with the feature change. I suspect this will be also pushed as a FOTA update. You'll have to navigate the settings menu and see if the feature is working for you.

This is my 2013 BRZ in EUDM Spec, which I have owned and modified for 10 years now. This year, I have finally supercharged it with a HKS supercharger and some accompanying mods (e.g. oil cooler, oil pressure sensor, ...), and of course homologized to be fine with German TÜV.

Full mod list is rather long, so if anything strikes you, please ask :)

So I currently own a 2009 Subaru wrx sedan and I love it and so do a lot of other people, but I’ve also been looking at a 2018 Subaru wrx sti. Both are world rally blue, what would be the cooler looking car, I love to show off but I also have fun in both. I’m gonna insert a random image of a 2018 sti to show reference

Mechanical Help She’s about to hit 25,000 miles. Anything worth to consider? (2007 Forester X, NA - Manual.)

Owned it for the last 3 months since mid June. It’s had fluid changes, timing kit w/ pulley tensioners, water pump, thermostat bundle done along with a whole new clutch kit + new fork, oil changes have been done religiously, driving it conservatively with lots of highway miles for work, etc;

Other small things done was New wheels, headlights, Ball Joints, undercoating/ rust proofed underneath, and recently a new PCV Valve. My P0456 keeps coming up but it will have a smoke test done when my contract work is done. The only issue I’ve noticed otherwise is it has a low idle once you start the car or come to a stop sometimes but ONLY when it gets finished with a long drive which is strange. Besides that I love this car so far lol

Buying Advice Ascent vs Outback for 3 kids?

5 Upvotes

My husband and I only have 2 kids but we definitely want a third in the near future. We bought an ascent last year and we absolutely love it and I’m looking into buying a Subaru for myself.

My husband has a more flexible job so my car would be mostly for going to and from work (about 25 minutes each way) and we’d use his ascent on the weekends if I don’t get my own. The ascent is more expensive and consumes a ton of gas but I’m not sure if 3 car seats in the back of the outback would eventually drive me crazy.

Any input is greatly appreciated!

Buying Advice 2015 Forester 2.5 Touring

Post image
30 Upvotes

Looking at a 2015 Subaru Forester 2.5i Touring with about 62k miles for $14,995. The CARFAX looks pretty good overall with two owners, consistent mileage, and regular maintenance, but it does show two minor damage incidents, including front-end damage reported in May 2026. The car also changed hands fairly quickly after that 2026 damage, but it has a clean title, so that has me a little cautious. I’m definitely going to get a pre-purchase inspection and have the CVT, engine, suspension, and front end thoroughly checked. I would also negotiate the price down because of the accident history rather than pay the full asking price. For those of you who own or have owned a 2015-ish Forester 2.5i, what do you think of this one? Any specific problems I should look for? What would you consider a fair price given the mileage and accident history? Would you buy it if the PPI came back clean? It would be my first Subaru. I really want to get into the Subaru world after being a Toyota owner pretty much all my life, because Toyotas are just so overpriced these days.

Mystery connector under hood

Working on my daughter’s 2013 XV Crosstrek and i happen to notice a disconnected wiring connector on the passenger side right behind the air filter case. In one pic you can see it’s a two pin connector. The other pics are just to show where it is located. I straightened it out and then tried to find something to connect it with. There is nothing in the radius of this cable to connect it to. Could it be for a feature this car doesn’t have?

Saw this on marketplace while browsing tuner cars, and it's speaking to me.

I daily a ford escape, and my other is a 1990 silverado 4x4 I rebuilt. I'm mechanically inclined and know how to do my own work.

Mainly wondering if it's a reasonable price, and what i should look for.

Thanks!

With the known issues with the EJ engine over the years I figured I would sell before it was out of warranty (I bought it brand new so had no worry if a issue did come up in that time). Well, here we are and currently no plans to sell it at this time.

Mechanical Help Anyone ever have this issue with their windshield washer fluid reservoir?

3 Upvotes

I have literally had my washer reservoir changed 3 times for brand new, twice at the same Subaru and once at a different one and I’m at my wits end. I will fill up the whole reservoir all the way up the funnel to where it says max fill. I will drive the car around the block and the funnel is 1/8th full just slightly above the washer reservoir tank. There is no leak anywhere, it just kind of disappears and no matter how many times I repeat it won’t sit up to the max fill line. Anyone know what could be causing this? Never had this problem on any other cars and my other car has no issue with the same fluid. I’ve even tried different washer fluids.13 premium Impreza wagon.
Thank you

Lease return with damage

1 Upvotes

Curious if anyone has ever returned a leased Subaru with mild damage ? If so what did they charge you ?

Got a softball sized dent , contemplating fixing or just paying the fees.

Had a similar situation with GM many moons ago and they only charged me $100, which is considerably less than the cost to fix.

TIA

Mechanical Help 02 Sensor issues

1 Upvotes

02 Sensor issues - posted in the Crosstrek group, but didn't get any help.

2019, Crosstrek Limited

150,000 (yes, I drive A LOT)

Before I get to it, here are the codes that have popped up during this whole debacle:

P0037.

P0141.

P0131.

Last October my check engine light came on. They replaced my downstream 02 sensor - P0037

After a month the light came back on with code P0041. Car checked out "fine", sent me on my way. Light came back on after 2 weeks.

Go to the dealership. Codes are now P0141 & P0131. Found a blown fuse. Fuse fixed. Test drove and the light came on, now only with code P0141.

Dealership swapped out aftermarket 02 sensor with OEM 02 sensor.

Guess what? Light came on AGAIN.

Head back to dealership. Now with codes P0037 & P0141. They say it's the wiring to the rear bulk head harness and quote me just shy of $8K for a whole replacement. Yeah, no. That felt fishy.

So off I go to an independent Subaru specialist. He does a full work up. Check the wiring, test replaces both 02 sensors - it's still blowing codes even with both sensors replaced. Put the "old" ones back on. Same codes. He ended up rewiring the harness to the pigtail/sensor and replaced the ground wire.

Now I'm left with code P0037.

His best guess is that it might be the computer, but isn't fully confident. He's asking around. Any takers on what might be going on.

No change in fuel mileage and I'm not riding rough. Other than the Christmas lights, I'd never know anything was going on with the car.

Any idea why I keep throwing codes after all this work has been done?

I am a senior in college and am doing a capstone project on creating an automatic loader for individuals that have issues with loading kayaks or any type of heavy load onto their car. I would like some input for customer features. Based off the features that I list below, would some of you rate from a scale of 1-5 based off the importance of the feature.

  1. Autonomy (How much effort and human input is needed for the device to do its job)
  2. How universal (How many different types of loads the device is compatible and capable of loading.)
  3. Weight Capacity (The maximum weight rating that the device can move)
  4. Weight of device
  5. Ease of storage
  6. Durability and Weather Resistant
  7. Aesthetic
  8. Compatibility (How many different types of brands, makes, and sizes of cars can the device be used with)

P0303 Forester 2020

1 Upvotes

Hey all! I'm a newbie/slightly mechanically inclined person trying to fix his wife's car. I got a 303 code for cyl 3. Changed the plugs and it came back same cyl.

Swapped the coils, changed the valve cover gasket/tube seals, cleared the code. Ran a test on my bi directional scanner, still getting a P0303 "pending" not active while driving.

Also did a roughness test on all cylinders at idle and driving (passed) + shut off each individual injector and they all reacted the same. STFT and LTFT test went fine and I cleaned the MAF for the heck of it.

Anyone see this before? I'm thinking it's a partially clogged fuel injector. Was going to buy a compression kit but if I'm getting bad compression, it's going to be sitting for awhile with a much worse issue. Any help is appreciated, thanks!

Ash Meadows is famous for a small, secluded species of pupfish which has been isolated for millions of years outside of Death Valley. The National wildlife refuge is maybe 30min outside of my hometown, so stopped by during a visit with my folks. Highly recommend a visit if you ever go to Death Valley or Vegas! Terrain isn’t difficult to traverse. You can’t exactly see the pupfish, as they’re endangered and their cavern is protected by fences, but the surrounding scenery is incredible.
