4. Filed Aug 6, 2026Failure Jul 25, 2026Warren, MIService brakes, Steering, Unknown or other

   I am reporting two issues with my vehicle that I believe require further attention and repair assistance. I am requesting that both issues be properly repaired without any charges to me. There are no warning lights, error messages, or other dashboard warnings related to either issue. However, both conditions are abnormal and affecting the vehicle’s operation and ownership experience. 1. Steering Noise (Inside Cabin). The steering assembly inside the cabin. Whenever I make any type of turn, either left or right, I hear a noticeable clicking/clocking noise coming from inside the steering column area. I want to clarify that this noise is not coming from the wheels, tires, suspension, or steering components connected outside the cabin. The sound is specifically coming from the steering wheel/steering column area inside the vehicle. I have had this concern checked, and the only suggestion provided was to replace the suspected component. The dealer did not provide written confirmation of the diagnosis but verbally advised that they could replace the component and see if it resolves the issue. However, since there is no guarantee that the replacement will correct the problem, I do not feel comfortable spending my own money on a repair that has not been confirmed. I have also spoken with multiple third-party mechanics, and some have verbally indicated that this type of steering noise is a known issue that can occur after a few years and may be related to the clock spring (spiral cable/ribbon) or another internal steering column component. Because this appears to be a known manufacturer-related concern and not a result of misuse or neglect, I request that the issue be properly repaired at no cost. 2. Rear Brake Squeaking Noise. The rear brake pads and rotors are new, but the brakes continue to make a noticeable squeaking/squealing noise. The noise usually occurs after driving for some time, especially in warm weather when the brakes reach normal operating temperature.

   On XXX, I was operating my vehicle heading Pocono PA, on I-80 in [XXX]. At approximately mile point 142.4, the vehicle's onboard Forward Collision Avoidance System (FCAS) suddenly and unexpectedly activated without any obstruction, hazard, or vehicle ahead. The abrupt, automated braking and system intervention caused an immediate loss of vehicle control, forcing the car into a 180-degree spin. The violent shift in momentum caused the vehicle to roll over on the highway before coming to a stop. No other vehicles were involved in the initiation of the crash.

   2023 Subaru Ascent, under manufacturer basic warranty. Factory OEM battery has repeatedly failed. Voltage drops below 11.5V in normal use. Three documented failures in six weeks. SAFETY INCIDENT: Vehicle died on a public street and became completely immobilized. Brake warning light activated. Vehicle would not move even after a jump start. Passengers had to exit in a live traffic lane. A second vehicle was used to transport a replacement battery. The original battery is in my possession and available for inspection. A subsequent failure occurred when the original battery was reinstalled for a manufacturer-required diagnostic. Vehicle again would not start. KNOWN DEFECT: Subaru TSB 07-213-22R (revised 03/28/24) covers the 2023-24 Ascent battery and acknowledges the factory specification as inadequate, directing dealers to replace the battery, tray, cover, and holding rod with higher-capacity parts. This TSB was not proactively applied to my vehicle. The dealer did not identify or disclose it at earlier service visits where the battery concern was reported and "could not be reproduced." No recall or proactive owner notification has been issued. Dealers are not applying the TSB preventively. A complaint is open with Subaru of America Customer Advocacy. The manufacturer has declined to reimburse the out-of-pocket emergency replacement and has required a dealer diagnostic that has been repeatedly blocked by manufacturer/dealer procedural requirements.

   In 2024, 2025, and 2026, I have had 2 incidents in each year where the cruise control is set to 60 to 65 mph and the cruise control then accelerates the car past 100 mph. When this occurs, tapping the break does NOT disengage the cruise control. All 6 times I have had to slam the breaks to a full dead stop while the car tries to accelerate anyway. April 4, 2026 and April 14, 2026 are the most recent occurrences and all occurrences so far for this issue have been during a downhill road incline. The dealer has dismissed the problem every time and has been unable to fix or reproduce the problem on demand. The random frequency of this problem can easily lead to a significant accident for the driver or others in the vicinity. And the lack of resolution from the Subaru dealer has lead me to report the issue here in hopes that if this is occurring for other vehicles that the company takes an actual resolution to solve the issue in their cruise control function.

    I was entering an intersection to make a left-hand turn. I was driving at a low speed. My foot was pressing the accelerator and the car entered the intersection. In the middle of the intersection, the car wheels suddenly stopped turning. There was nothing in front of the car. Cars behind me began honking since my car stopped suddenly and unexpectedly while I saw a notice displayed on the car messaging, but I do not know what it said. I am unsure if the car engine turned off or not, but I remember turning on my hazard lights, putting the car in park and pressing the start button. I was able to drive out of the intersection to a safe location and turned off the car engine. I restarted the car and drove immediately to the dealer where I purchased the car from for them to evaluate it. It is currently being submitted for diagnostics at the car dealer. I told them I would make this safety report while I waited.

    When crossing a bridge at 40 mph with wide open lanes and shoulders the vehicle on cruise control suddenly braked aggressively and came to a full stop in the middle of a state highway bridge. Conditions were daylight, headed towards sun, no shadows on bridge. The road surface was smooth asphalt. There were shoulders as wide as the active lanes. There was no warning and very little time for a driver reaction. This type of vehicle behavior will most certainly cause rear end collisions.

    Incident Description – Event 1 On August 28, 2025, at approximately 4:45 p.m. while driving on Sugar Ridge Road, my 2023 Subaru Ascent suddenly jerked violently into the left lane without warning while the EyeSight Driver Assist system was active. I had to take immediate corrective action to maintain control and avoid a head-on collision. This behavior has occurred on multiple occasions under similar circumstances. My husband has also experienced the same issue while driving, which demonstrates this is not an isolated event. Incident Description – Event 2 On multiple other occasions, while the EyeSight Driver Assist system was engaged, the vehicle veered dangerously close to a semi-truck traveling beside us. I had to react instantly to prevent sideswiping the truck, which could have resulted in a severe accident. We have noticed this behavior occurs nearly every time we are alongside a semi-truck on the highway.

    The passenger-side mirror on my Ascent has been damaged and removed since March 2025. I paid for the part on April 8, 2025 and was told it would arrive in a few weeks. As of July 1, 2025, the part has been delayed until August. The mirror is critical for visibility and safe operation. My wife drives this car daily with our infant. Subaru has refused to provide a rental, and the car is unsafe. I’ve contacted Subaru Corporate with no resolution, despite my continued persistence in contacting them through visits to their dealership in Plano, TX and several emails.

    I am filing a formal complaint against Subaru of America regarding a safety defect in my 2023 Subaru Ascent (VIN: [XXX] ) and their failure to honor warranty and recall obligations. Subaru issued recall TSB 06-92-24 to address front brake vibration by replacing rotors and pads with upgraded parts. My vehicle received this repair in September 2024. Less than 9,000 miles later, the exact same symptoms returned—steering wheel shaking and brake pulsation. In April 2025, Subaru resurfaced the upgraded rotors instead of replacing them, violating their own TSB, which prohibits unnecessary resurfacing and mandates rotor replacement if runout exceeds 0.05 mm. An independent inspection dated April 9, 2025, confirmed: Left front rotor measures 29.0 mm with 0.5 mm runout (10x Subaru’s limit) Right front rotor also measures 29.0 mm Subaru’s dealership claimed the rotors were 30.09 mm and 29.50 mm—inaccurate and misleading Subaru returned the vehicle in an unsafe condition with documented brake system defects. Their customer service insists the vehicle is “operating as designed,” despite clear evidence to the contrary. I am requesting regulatory review and a full buyback or enforcement of proper warranty compliance. Photos, inspection documents, and invoices are available.

    Formal Complaint Summary (VIN: [XXX] ) I am submitting this formal complaint concerning a 2023 Subaru Ascent Onyx Edition Limited (VIN: [XXX] ), which continues to experience brake-related safety defects despite recall repairs and repeated service attempts during the warranty period. Subaru of America issued Service Bulletin 06-92-24 in July 2024, which extended warranty coverage and acknowledged systemic issues with front brake components—specifically brake pulsation, squealing, pedal softness, and vibration. Subaru developed new components and repair protocols to address these issues, including new rotors, tie bars, pad kits, and a revised installation process. In September 2024, I brought the vehicle to CMA’s Subaru of Winchester after experiencing symptoms covered under the recall. Subaru replaced all required recall components. However, the defect returned in March 2025, while driving from Indianapolis to Winchester, now worse than before—resulting in violent steering wheel vibration, loud grinding noises, and unsafe braking behavior, particularly during downhill braking. Instead of replacing the parts again, Subaru resurfaced the upgraded rotors—despite the bulletin’s warnings against doing so. This resurfacing served as a temporary patch, not a true fix, and failed to resolve the underlying safety issue. I have made 21 lease payments totaling $13,707.96 and paid a $6,000 down payment, totaling $19,707.96 in out-of-pocket costs. Subaru has offered only a $2,500 goodwill payment, which I rejected. Relief Requested: I am requesting a full reimbursement with buy back under Magnuson-Moss Warranty Act. Investigation to the reoccurring break issues despite being serviced for a recall.

    2023 Subaru Ascent Touring. Front windshield easily cracked from minor rock strikes 3 times within 20 months. Replacement with Subarus OEM glasses twice already within 3 months. Now a new crack needs repair or potential replacement. Defective windshield that cannot withhold minor impact is clearly serious safety concern, increased stress on owner and burden on insurance, and impact to vehicle structural integrity for repeated replacements, and depreciation of vehicle value.

    Unusual wear on tires - 7/32 at 8000 miles, 5/32 at 15000 miles, advised to replace all tires at 15000 miles. Existing recall WRH-23 covering vehicles manufactured between Dec 2022 and Jan 2023. My vehicle shows manufacturing date of March 2023 but I believe may be part of the same issue. See below Subaru of America, Inc. (Subaru) is initiating a new safety recall and stop sale for certain 2023 model year Ascent vehicles equipped with 20-inch wheels. Description of the Defect and Safety Risk The vehicles included in this recall/stop sale may be equipped with tires that were damaged during the wheel mounting and assembly process. A misaligned bead guide arm on the tire mounting equipment may have caused excessive stress on the tire bead during mounting, possibly causing damage to the internal structure of the tire. Internal damage to the tire bead may lead to structural failure of the tire and rapid tire deflation, increasing the risk of a crash. Remedy For all potentially affected vehicles, Subaru retailers will remove and replace all four tires with new ones at no cost to the customer. All removed tires should be rendered unusable and be disposed of according to local regulations. Affected Vehicles A total of 4,409 U.S. Subaru Ascent vehicles will be affected by this recall, as listed below: 2023 Ascent (w/20” wheels) December 1, 2022 – January 5, 2023 Not all vehicles in the production date range listed above are affected by this recall.
