2021 Subaru Ascent Brakes Problems

Your brakes shudder and lose stopping power when you slow down from highway speeds. This problem keeps recurring even after Subaru has attempted multiple repairs, including a front brake warranty extension program. The issue may require brake system inspection or replacement of brake components.

Your car's automatic braking system engaged suddenly while driving on an empty road with no vehicles in front of you or nearby. This has happened multiple times before, creating a potential safety hazard if another car was following closely behind. The system appears to be activating incorrectly without a valid reason. A diagnostic scan of the forward collision avoidance system and its sensors may be needed to identify why it's triggering false braking events.

Brake rotors, front and back warp. Rotors have been replaced and resurfaced multiple times. The vehicle is over-sized for the braking hardware included with the vehicle. I have spoken to the dealer multiple times and they are aware of the undersized brake component issue across this model line. Although promised, Subaru has not addressed the issue and it is a safety hazard in hilly terrain.

Started having problems with the brand new car shaking and brakes making grinding noises when stopping around 20K miles. Brought the car to the dealership and they ended up replacing the brake pads and rotors. It’s been just over a year and less than 15K miles since the replacement and the car started shaking and brakes are making a grinding noise again. Again took the car to the dealership and the rotors are bad. After further research, this is a constant and known issue and has yet to be resolved by Subaru. Instead they wait for the new car warranty to wear off and let their customers pay out of pocket to have this fixed. Some owners have had to replace up to 4 times in less than 40K miles.

Front brakes (pads and rotors) had to replaced 2 times. The dealer said that Subaru used undersized pads and rotors on the bigger Ascent model. The brakes were not designed for such a big vehicle, and it has been a known issue. The brakes were replaced under warranty, but my warranty will expire soon. I'm stuck replacing and poorly designed braking system, that is a known issue.

Vehicle braking reduced to about 10%. Brakes was making lots of noise and couldn’t stop for almost 1/4 mile. Managed to stop vehicle was taken to dealer. Calipers were changed and rotors serviced. After several trips to dealership for repairs to brakes vehicle still having braking noise and reduced stopping power which gets worst with time.

Car purchased in August 2021. Front brake rotors and pads were replaced around 7,600 miles and May 2022. They could not "cut" the rotors as they were pitted beyond being able to be cut. At 10,764 miles (August 8, 2022), the front rotors and pads were replaced again. The dealer stated the front pads had tiny chips in them and the R/F outer pad had a crack in it. The rotors also had excessive heat spots on them and small pits. The last few days the brakes have been pulsating lightly on hills and today have begun pulsating at every stop. Car now has approximately 11,700 miles on it. Subaru has been notified and I will be making an appointment with dealer on Monday.
