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.
