Service brakes

10 reports2 crashes
“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.

Forward collision avoidance

7 reports1 crash
“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.”

Visibility/wiper

6 reports
“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.”
