SERVICE CAMPAIGN BULLETIN
| SUBARU: | 2019-24MY ASCENT |
APPLICABILITY
2019-24MY Ascent
INTRODUCTION
In the interest of customer satisfaction, Subaru of America, Inc. (SOA) is extending the New Car Limited Warranty coverage for the front brake on 2019-24 model year Ascent models to 8 years (96 months) or 150,000 miles (whichever comes first) to address cases of front brake pulsation or squealing.
In addition, this bulletin announces availability of a new diagnosis/repair procedure developed to address concerns of a squeal type sound occurring when applying the brakes. An additional tie bar component has been developed to provide added rigidity and reduce noise/vibration. The number of brake disc cooling fins has increased from 41 to 47. If a squeal type sound and/or pulsation from the front brakes is reported by the customer, follow the service procedures outlined in this bulletin.
PRODUCTION CHANGE INFORMATION
The new brake components have been incorporated into vehicle production as per starting VIN R3417029 .

IMPORTANT NOTES:
DO NOT install both old and new type parts on the same vehicle. These new components MUST be replaced in pairs.
In cases where a vehicle has been previously equipped with a tie bar, the original tie bar is to be reused.
In cases where a vehicle is not equipped with tie bars, it is CRITICAL to use the new bolts (p.n. 26208XC000) in conjunction with the tie bars (p.n. 26261XC000).
SERVICE PROCEDURE/INFORMATION
The following service procedure has been outlined in an instructional video along with a post test for additional Technician reference.
Front Brake Pulsation-Squeal Video
STEP 1: Perform a road test and confirm a brake squeal and/or pulsation condition is present. Use the table below to confirm the next course of action.
| Condition | Course of Action |
|---|---|
| Front Brake Squeal Only | Proceed to Step 3 |
| Front Brake Pulsation Only | Proceed to Step 2 |
| Both Front Brake Squeal & Front Brake Pulsation | Proceed to Step 3 |
STEP 2: Raise the vehicle using the lift manufacturer's specified procedures. Remove both front wheels. Inspect the brake disc part numbers to confirm the brake disc version currently installed on the vehicle. See the images below for part number location.
Is the vehicle currently equipped with the new brake discs?
YES: Resurface the brake discs using a Subaru approved brake lathe. Perform a road test and confirm there is no front brake squeal/pulsation. Record and note the before and after brake thickness.
NO: Proceed to Step 3.
STEP 3: Starting at the left front wheel, remove the pad clip.
STEP 4: Remove both dust caps (a). Using an 11 mm allen key, remove both guide pins (b). The caliper body can then be removed.
STEP 5: Remove the inner and outer brake pad.
STEP 6: Remove the caliper bracket mounting bolts and then remove the bracket. The mounting bolts removed during this Step MUST NEVER BE REUSED during re-assembly. Discard the original mounting bolts. The front left brake disc can then be removed.
STEP 7 : Using a dial gauge, inspect for any excessive play in the axial direction of the front hub bearing. Confirm the observed measurement is below the service limit of 0.05mm (0.002 in). If the measurement exceeds the specified value, the front hub bearing will require replacement. Record and note all measurements.

STEP 8: Install the new brake disc. Secure the disc to the hub using the five lug nuts in conjunction with matching suitable washers. Torque the lug nuts in a star pattern to 120 Nm (88.5ft-lb). Using a dial gauge, inspect the outer brake disc runout. Confirm the observed measurement does not exceed 0.05 mm (0.002 inch). If the measurement exceeds the specified value, remove the brake disc from the hub. Using the wheel studs as a guide, rotate the disc clockwise one wheel stud position and reinstall the brake disc. Inspect the runout using the procedures described above. The brake disc position can be rotated up to 4 more times to confirm the position with the least amount of runout. Install the brake disc at this position. In rare cases of the measurement not reading within specification after the five position inspection, exchange the brake disc with the other side of the vehicle and repeat the measurement. If the measurement continues to produce results out of specifications, replace the brake disc. Record and note all measurements.

STEP 9: Apply a thin layer of the Kluber grease to the caliper bracket in the locations outlined in yellow specified below.

STEP 10: Apply a thin layer of the Kluber grease to the caliper in the sections specified below.
STEP 11: Pre-assemble the new mounting bolts and the new tie bar as shown below.
STEP 12: Reassemble the left front brake caliper bracket, caliper, and pads along with the tie bar and mounting bolts. Torque the mounting bolts to 142 Nm (104.7 ft-lb).
STEP 13: Repeat Steps 3-12 on the right front side of the vehicle.
STEP 14: Reinstall the left and right front wheels and torque to 120 Nm (88.5ft-lb).

OWNER NOTIFICATION LETTER

IMPORTANT NOTICE:
Warranty Extension for Ascent Front Brake Judder/Squeak on certain 2019 to 2024 MY Ascent Vehicles Manufactured PRIOR to January 11th, 2024
Dear Subaru Owner:
As part of Subaru of America's dedication to customer satisfaction, Subaru of America, Inc. (SOA) is announcing a warranty extension to the front brakes on 2019-2024 MY Ascent Vehicles Manufactured PRIOR to January 11th, 2024.
Affected vehicles are equipped with front brakes that may, under certain conditions, exhibit a squeak or squeal type noise or a judder type feel when coming to a stop.
If your vehicle is operating as expected, you do not need to take your vehicle to a Subaru retailer for repairs.
ASCENT FRONT BRAKE WARRANTY EXTENSION COVERAGE
For qualifying repairs, this extension covers the costs of diagnosis and replacement of the front brake components-brake pads, rotors, and tie bars with bolts-with newly developed parts. The extended warranty coverage will end once the newly developed parts have been installed.
Most parts are available now, with the new brake pads expected to arrive at your Subaru Retailer by December 2024. In the interim, this extended warranty will cover any qualifying repairs using currently available components.
The coverage period extends the New Vehicle Limited Warranty as it applies to the front brake components to eight (8) years or one hundred and fifty thousand (150,000) miles, whichever occurs first, or until the newly developed parts have been installed in your vehicle.
Inspections or repairs under this coverage period must be completed prior to the expiration of that eight (8) year period, or before 150,000 miles, whichever comes first, calculated from your vehicle's in-service date.
Effective from the date of this customer notification, ALL affected vehicles regardless of the vehicle's mileage and warranty start date will be covered for these repairs for a period of one (1) year.
If you have questions about this notice, please contact the Ascent Front Brake Warranty Extension Hotline at 877-551-7149. Additional information can be found online at: subaruclaims.autosolutionsteam.com

The period of reimbursement shall be One (1) year from customer/retailer notification of this warranty extension.
- You must have paid an out-of-pocket expense for a repair that would have been covered had it occurred during the warranty coverage period. This includes any deductible expense or partial reimbursement for repairs.
