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.
NHTSA complaint #11755178 — an unverified report by a vehicle owner.
Replaced rear brakes and rotors in August 2025. By may 2026 they had worn down to the metal and needed replaced again. Only had 13000 miles on them. After multiple diagnostics testing was done, no issues were found with the brake system. Monitoring new pads and rotors. Still wearing rapidly but even. After only 6 weeks, they have reached about half of their life.
NHTSA complaint #11747480 — an unverified report by a vehicle owner.
The car will spontaneously brake for no reason while driving forward and reverse. The steering wheel will spontaneously steer you out of the lane. The doors will lock while you are in the car and you can't get out for about 30 seconds. The deck door will come down on you unexpectedly while loading items. It has hit us in the head or makes us twist our back to lift it up. The stereo system has a mind if it's own. The eye site goes on and off for no reason. These safety issues concern us. We have had it in the service department three times and they can't duplicate the problem. They have had it since June 6th and drove it 30 miles in 20 days. I don't think they drove it long enough to duplicate the problem. It usually happens after about 15/20 minutes of driving. Typically that is about how long before the brakes will spontaneously brake.

On May 14, 2026, while driving a 2021 Subaru Ascent (approx. 94,291 miles) on a Texas expressway at highway speed during rush hour, I experienced a sudden and significant loss of engine power. There were no warning lights, no safety system activation, and no advance indication of the failure. The vehicle decelerated abruptly with traffic behind it. Live OBD-II data was being logged during the drive and was provided to the service advisor at the authorized Subaru retailer. This incident occurred only 3 days and approximately 125 miles after the vehicle was returned following a major engine repair performed at an authorized Subaru retailer in Texas under active powertrain warranty. That repair was supervised by a Subaru of America District Quality Manager and Field Technical Specialist, who conducted a 110-mile validation drive prior to release. Prior to the highway failure, visible fluid leaks were documented across the intake ducting, residue on lower engine components, a sweet and burning odor after driving, and milky sludge returning to the coolant reservoir — all within 125 miles of pickup. These are consistent with ongoing oil and coolant cross-contamination, which was the original diagnosis documented in the dealership's digital service portal. The vehicle has now undergone three major engine teardowns since March 17, 2026 — over 100 days out of service — for the same underlying powertrain issue on the FA24 engine. The current repair involves cylinder heads sent to a third-party machine shop. Vehicle telematics confirm the vehicle has not been started since May 27, 2026. This report is filed to establish a federal safety record of the highway power loss incident and the recurring nature of this powertrain failure. An active Subaru of America customer advocacy case is on file regarding this vehicle.

I am reporting a repeat safety concern involving a 2020 Subaru Ascent. The vehicle was involved in two separate collisions after failing to decelerate as expected following normal brake pedal application. The first incident occurred on January 26, 2026. While approaching a traffic signal, I applied the brakes under normal driving conditions. The vehicle did not slow as expected and struck the rear of another vehicle. Property damage occurred, but no injuries were reported. The second incident occurred on May 5, 2026. While approaching a stop sign at approximately 35 mph, I again applied the brakes under normal driving conditions. The vehicle did not decelerate as expected and entered the intersection, colliding with a vehicle traveling perpendicular to my direction of travel. Both vehicles were towed. No injuries were reported. During both incidents, there were no forward collision warnings, automatic emergency braking interventions, or other alerts observed prior to impact. Following the second collision, the vehicle was inspected by an independent technician. Brake components inspected were found to be within serviceable condition and no evidence of neglect or improper maintenance was noted. During inspection, abnormal brake pedal behavior was observed, including continued downward pedal travel while steady pressure was applied. The technician documented that the reported condition was not consistent with normal braking performance and stated that an intermittent hydraulic and/or brake assist related issue could not be ruled out. The vehicle has been regularly maintained according to manufacturer recommendations. Due to the repeat nature of the condition, the lack of warning or intervention from safety systems, and the occurrence of two collisions despite normal brake application, I believe this condition represents a significant safety risk. The vehicle has since been declared a total loss and may be available for further inspection.
NHTSA complaint #11740848 — an unverified report by a vehicle owner.
In December 2025, I had brake replacement, tire service, and wheel alignment performed at Monro Auto Service located at [XXX] child were traveling on the highway during a winter storm when the brakes began making a loud banging noise. My wife was unable to immediately locate a service location and was forced to continue driving for an extended period in winter storm conditions while in fear for her safety and that of our child. When she was finally able to reach a second Monro location between [XXX] and [XXX] , a technician discovered that one brake caliper bolt was missing entirely and a second was dangerously loose. The vehicle had been driven at highway speeds in a winter storm with an improperly and incompletely assembled brake system for an extended distance before help was found. The second Monro location secured the caliper bolt and confirmed the vehicle safe to continue. The original Fairport location was contacted and their manager acknowledged the issue but has failed to provide any meaningful resolution after nearly four months. In a formal BBB complaint response, Monro Inc. confirmed that the caliper bolt had not been properly secured and acknowledged filing an insurance claim for resulting rim damage — an implicit admission of negligence. I am filing this complaint because an improperly assembled brake system — specifically a missing caliper bolt — represents a serious and potentially fatal safety hazard. If this is a pattern of negligence at Monro locations, other consumers may be at risk. BBB Complaint Case #XXX is on file documenting Monro's formal response and admission.

NHTSA complaint #11735368 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11733168 — an unverified report by a vehicle owner.
The contact owns a 2026 Subaru Accent. The contact stated that there was a failure related to the brake pedal design. The contact stated that there was an approximate one-inch difference in spacing between the brake pedal and the accelerator pedal in previous model vehicles. The contact stated that there was an approximate four-inch gap between the brake and accelerator pedals, while previous models had an approximate three-inch space. The contact stated that the difference created a hazardous driving condition and increased the risk of unintended pedal application. Additionally, there were several instances where a crash could have occurred due to the pedal spacing. The vehicle was taken to the dealer; however, it was not diagnosed or repaired. The dealer informed the contact that several complaints were received with the same issue and referred the contact to the NHTSA Hotline to report the failure. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,040.

NHTSA complaint #11689564 — an unverified report by a vehicle owner.
The contact owns a 2022 Subaru Ascent. The contact stated that while driving 30 -35 MPH and depressing the brake pedal, there was an abnormal rumbling sound coming from the vehicle. The contact stated that the vehicle stopped and resumed driving repeatedly. The contact stated that the vehicle failed to respond as intended, causing the braking distance to be extended. There was no warning light illuminated. The contact was able to drive to the residence. The vehicle was taken to the local dealer, where an unknown diagnosis and repair were completed. Additionally, the contact stated that the same dealer had previously repaired the brakes under warranty. The manufacturer was contacted and advised the contact to retrieve the vehicle from the dealer even though the contact had safety concerns. The failure mileage was approximately 38,000. The VIN was not 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.

NHTSA complaint #11653574 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11653634 — an unverified report by a vehicle owner.
My 2024 Subaru Ascent started experiencing brake issues in early January. The car would shake heavily and make noise when braking, despite having only 10,500 miles. Concerned, I contacted Subaru of America and was advised to take it to a dealership for an inspection. On 1/31/25, the dealer inspected the brakes and determined that the front rotors and brake pads needed to be replaced. Subaru of America confirmed that the dealer would order new parts for the front brakes. A few days later, I received an email from the dealership stating that the new rotors and brake pads had arrived, and they scheduled me for service on 2/14/25. However, after waiting at the dealership for three hours, I was informed that instead of replacing the rotors as initially promised, they had simply resurfaced them. The explanation given was that these were already “upgraded” rotors. This raises serious concerns for me—if these rotors were already upgraded, why did they fail before 10,000 miles? This is a clear safety issue, and I am increasingly worried that both Subaru of America and the dealership are not properly addressing the situation. I was supposed to receive brand-new rotors, yet I am now left with resurfaced ones, which does not give me confidence in my vehicle’s safety. I need a proper resolution to this issue. Potentially Subaru America should issue a safety recall for these breaks.

Brakes shudder and fade when slowing down from highway speeds. Subaru has issued many "fixes" but it keeps happening. See most recent "Ascent Front Brake Warranty Extension Coverage" it still has not fixed the problem!
NHTSA complaint #11616364 — an unverified report by a vehicle owner.
There was a SUDDEN and UNINTENDED acceleration without the driver input while braking to park going approximately 1 - 2 MPH. Our safety was at risk. The vehicle was not in our control. A police report was generated. Rather than stopping we crashed into the apartment building causing significant damage to both the apartment and our vehicle. There were no warnings, no automatic braking to avoid the collision, the air bags did not deploy. The total damages are still being determined by the dealer and insurance company.

The emergency brake occasionally comes on for no apparent reason. It has happened multiple times before but, never while driving until today. The button appeared to be stuck when I went to disengage it as well which made no sense. There was nothing in the way for it to get stuck. Upon further research in the Subaru forums it appears ours is not the only one to have experienced this. This leads me to believe there may be an unknown issue.
