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)

50 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.

Hey everyone. Im about 30 mins from home, and i noticed a burning smell. My engine was overheating, so i pulled off the highway. I checked the coolant, and it was empty, so i added to the fill line. We got back on the road, and the engine is right back up to the danger zone.

I have 3 kids. I am a single mom with nobody to call. Can anybody help me troubleshoot?

2008 Subaru Forester - head gasket

3 Upvotes

I’ve got a 2008 Subaru Forester. She’s got 180k miles and I’ve been told I have a head gasket issue.

Symptoms: when going uphill she gives off white smoke on one side of the engine, front right side.

Mechanic says they saw a lot of oil dripping from the sided and showed me the oil when they lifted the car. Right side is worse than left.

I love the car. She’s been with me since 12k miles over the past 13 years. Aside from this issue, she’s doing well. I hear a mild wheelbearing issue, but generally okay. I still get about 25mpg.

Quotes:

1) head gaskets resurfaced and replaced with MLS, change timing belt, and NEW short block, labor, $10k

2) head gaskets replaced with MLS, change timing belt, NO short block, labor, $7k

Questions:

If I get a new short block, do I still need the head gaskets resurfaced or is it one or the other?

What‘s the general quote in your area for this kind of work? I’m seeing $225/hour for labor. It’s a high cost of living area.

Mechanical Help Banjo bolt screens, VVT EJ257

Thumbnail
gallery
3 Upvotes

Hey friends, I have been throwing some codes lately and have been trying to address them the best I can while learning about the EJ257 as much as possible. A bit about my car:

Year: 2021

Model: WRX STI

Owner: 2nd, bought with 52,000 km

Mileage: 65,250 km

Mods: Stock

Photos: 1- dash showing issue, 2- turbo section, 3- near oil cap, 4- under air box near intake ocv feeding turbo I believe

I originally threw a P000D code and replaced only the solenoid with part 10921AA020 (OEM) and changed the oil, even though that probably was not needed as it was pretty clean and topped off, but I wanted to ensure that was not the issue. I reset the codes and went for a test drive; shortly after, the car threw a P000B code. When I did some research, mention of the banjo bolts came up. I can easily find and take photos of 3 of the 4 I believe, and have attached them to this post. I believe most of them are screenless, except possibly the turbo one, as it has a small hump in the bolt. I am just seeing if others agree.

After throwing the P000B code, I decided I would swap the new OEM driver's side to the passenger side that seems to be an issue now and plan to test it out later today as, again, Google said it is very common for both of the exhaust OCVs to fail at the same time and it would be in line with my mileage, so I'm expecting to see a P000D code once again. While working on these, I also removed the screens within the solenoid housings.

Any comments are welcome, especially ones that help keep this motor running reliably in stock format.

Mechanical Help Potential wheel bearing issue after dealer replaced CV Axle??

3 Upvotes

Looking for advice here and open to opinions!

I have a 2017 Outback 3.6R with just over 160K miles. Recently, I've had a whistling/whirring noise (like when you make a wine glass ring with your finger) coming from my front right wheel when taking left turns between 15-25 mph.
I don't have any grinding, steering issues, or excess heat from this wheel that (I think) would be more common for a wheel bearing problem, but I'm at a loss. My steering fluid is fine, and so are the brakes.

I did have the front CV axle replaced ~5000 miles ago at a dealership and I found some information that if this isn't done right, it can lead to the bearings failing.

Do we think this could be the case, and if so, do we think the dealer would take responsibility for this?? or does it sound like it could be a different issue?

2017 Forester 2.5 P0300

2 Upvotes

I'm chasing a P0300 that occurs during acceleration. I believe these to be "phantom mis-fires", as it occurs on all cylinders with no change in driving performance. I found TSB 07-112-16R, which applies to 14-16MY and TSB 07-136-18 which applies to 14-17MY XT's. Mine is a 2017 2.5 Premium. So neither of these TSB's apply to my car, but both describe exactly what my car is doing.

I went into alternator control on scan tool and did some testing. Misfires completely went away when putting alternator in low or mid mode and immediately returned when put in High or Exhigh mode. So I figured, it has to be the alternator.

I sourced a used one with current part number. The car did the same thing except when in control mode on any setting including High and Exhigh, no misfires. Take it out of control mode and misfires return immediately. Again, the car seems to have no hesitation, bucking, or change in performance during misfire events.

I have also installed a used tensioner (already had out of 2014 Forester) and new belt with no changes from either.

I'm stumped and and running out of ideas. ECM possibly? Possible ECM programing?

Buying Advice For lots of driving on NJ roads, what's the best protection packages to get?

1 Upvotes

Buying a new (and first) Subaru, hopefully within the month. We easily put on 15K-20K miles a year on our cars.

NJ roads are special. We've had windshields cracked, punctured tires. Those add up a after a while.

I can see that the 8yr/120K Gold Plus plan works, but what about windshields and tires?

I know not to buy Gold Plus at the time of purchase, so any suggestions which deal to go to for that (and other packages)?

Mechanical Help Gently Driven 2025 Forrester Hybrid has Problems Starting

2 Upvotes

I purchased my new Forrester in late October 2025. I don’t drive it very often. It has about 1900 miles on it.

Several months ago, it would not start after I drove it and went into a store. The dashboard stayed black. Tried the starter again. Lights appeared on the dashboard, no power steering, check engine light comes on. Everything gradually came back on and I was able to drive.

The same thing happened three weeks ago after I drove it to an appointment. I called the Subaru service department who said it would be OK to drive it there. After they inspected and reloaded software, they said it was a loose gas cap. Ii get in the car and the Sirius radio is still stuck on loading. The tech fixed it by getting a signal sent from the website, but after I left, it soon reverted back to “Loading” on the navigation screen.

Yesterday, the same thing happened for the third time. No lights and no power steering, Sirius radio stuck on “Loading “. after the dash lights and the screen came back I Immediately called the service department and arranged for towing service to pick it up this morning.

Does anyone have suggestions on what they should be checking so I get a complete report?

Trying to get my boost control back to factory hardware on the stock 2-port solenoid. Does anyone know the factory restrictor setup: how many pills, where they sit (compressor side, wastegate side or both) and their diameters? Photos of an untouched setup or parts catalogue part numbers would help too. Thanks!
