2020 Subaru Ascent: grinding or squealing brakes

Filed Jul 29, 2026 · Transmission · FL

The Transmission is slipping on my 2020 Ascent. I had the recall wrk-21 performed in July of 2025. Over the last 6 months the car has been hesitant to go at low speeds and shakes at high speeds. Over the last month the transmission started to slip while accelerating , especially up hill. There would be a grinding noise and RPMs would jump. I took it to the dealer and they confirmed it was the transmission via camera test. I called Subaru of America for goodwill help with the cost knowing that there is a know issue with the transmission. They refused due to the mileage, 121,010. •What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission is slipping •How was your safety or the safety of others put at risk? The car is hesitant to go from a starting position. The car will jerk back and forth when trying accelerate when merging or crossing a road. I am also very concerned of catastrophic failure at high speeds. •Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer has confirmed the transmission is bad via camera teat. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Just the dealership •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No dash lights just the feeling and sounds.

My strut bearings have been replaced several times in the drivers sides, my shock and strut has been replaced twice on the drivers side and now the passenger side is doing the same thing. The dealership tells me that there is nothing wrong but research shows this car has known suspension issues. My passenger side front has a loud metallic grinding sound when turning the wheel in park. I’m told this is the brakes which makes no sense. The car feels like it is on ice or sailing down the road, and the car does not maintain an alignment causing the insides of tires to wear out after 15,000-20,000 miles and need to be replaced.

The car has issues with rapidly deteriorating brakes. The brakes have been replaced twice and I feel they are bad again. This puts myself, anyone in my car, and any car around me at risk. The dealer is aware of the issue. Car was last inspected with the same concerns in mid-April to which the dealership responded the brakes are "like new". No one else has inspected the vehicle including the police or insurance representative. There was no warning lights related to the issue. I could just feel the brakes grinding. They were first replaced one year after purchasing the vehicle on 4/28/21. They were replaced again on 6/23/22. They feel like they are grinding again.

The braking system on the vehicle does not operate as expected on the vehicle. As a result a vehicle that only has 40k miles on a daily driver, is on its 3 set of rotors, 2nd set of brake pads( i declined having them changed at the 40k service) and 2nd set of tires. The brakes have not functioned comparably to any other vehicle that I have driven. They grind and the vehicle shakes when stopping. The issue grows worse with the increase in speed. I spoke with the service manager at the dealership and he informed me that Subaru is aware of the issue and it is common for this vehicle. The service manager stated that the rotors and calipers for the vehicle are undersized for the curb weight and it is an ongoing issue with the vehicles. I have spent thousand on maintenance on a vehicle that is 2 years old, an unreasonable amount. On the service managers recommendation I reached out to Subaru about the issue and was given a $600.00 coupon and told there is nothing else they can do and my issue was reviewed at the "highest levels". As I drive the vehicle now, I feel that the braking system is inadequate and the vehicle does not handle in a safe manner. According to Subaru, my only recourse is to spent thousands of dollars each year I own the vehicle at their dealership changing brakes and rotors with every oil change. Unacceptable.

Transmission is lurching and surging when driving. Pressing gas pedal from a stop the belt continues to slip. Took it to Paul Moak Subaru they claimed to do the inspection told me they don’t do test drives for malfunction checks. They said they completed the inspection for transmission recall. The Ascent continues lurch and slip with grinding noise and loss of speed. I told them about the issues for over a year and they continue to give run around I was having trouble while it was still under warranty. I’ve contacted Subaru Customer Care they would only provide me recall information and told me the trans inspection is all they have to do.

Since last NOV 2021, I have had this Ascent into the shop several times due to a 'chirping' or 'speaking' sound that comes from the underside of the middle o/t vehicle. I have come to find out through the service department that the primary differential has a batch of defective parts, and the entire differential needs to be rebuilt (21 parts total are being replaced). It has taken about 3 months to get parts in. The squeak was an annoyance. HOWEVER the situation got SIGNIFICANTLY worse when the wheels would not synchronize when turning - which should be unheard of because there are supposed to be sophisticated traction controls and such in place to prevent that very condition.

I’m very disappointed in the terms of the Subaru recall. Instead of just replacing the faulty transmission, they will only fix CVTs w/ evidence of problems. I reported transmission issues at my last service and was told to wait for the recall as they would charge me $175 if they couldn’t replicate the problem. So now I have to drive until at least May (probably longer with all the other recalled cars seeking appts) w/a faulty transmission that could cause an accident, while they figure out a remedy? Plus my 2020 Ascent will be out of warranty soon (6000 miles). So I’m stuck with paying to replace the trans, if these problems show up later? I’ve had so many problems w/ this car incl squealing brakes (my car was in the shop for a total of more than 4 weeks before they figured out how to fix this) and a hood that came close to Detaching at highway speed — I had to bring the NTHSA bulletins to the dealer to get them to admit these both were known problems that could be fixed. Please insist that Subaru do the right thing by just replacing the transmission NOW rather than waiting till May to figure out a remedy and exposing the owners of this problem-plagued car to further needless risk.

The vehicle has 19,000 miles and about 1 week ago the brakes started making an abnormal noise almost like grinding. The car also would vibrate and you could feel it on the steering wheel. We took the car to the dealer and turns out the brake rotors are warped. Their solution is to resurface the rotors and also resurface the brake pads. The car has not been repaired as this repair does not seem to be proper due they have not found the root cause for brake rotor warping. There is also a subaru service bulletin on brake issues. My main concern is the safety of my family. Subaru prefers to just resurface the brake rotors and brake pads as this is the lowest cost repair for them, though the car is still under full bumper to bumper warranty.

Battery dead 7 times (beginning fall of 2020) or drained too low to properly use vehicle causing all doors to lock (issue when stranded in non-populated area with child in car) or hatch unable to close. All items in vehicle are off. Appears to be electrical in nature and possibly related to in going subaru power-gate hatch issues. Have also had hatch open on own stationary & low speed. Often left stranded. Hard pulsating and grind on brakes at low to moderate speed causing car to pull and feel like not going to stop in motion on curved road, highway, city street. Started within year (aug 2020) of owning after 1st service at dealer for routine oil change. Dealer says nothing wrong at all. Subaru refuses to acknowledge issues even though other owners are experiencing same. Told by subaru lame excuses like not driving enough, shut everything off, do not use electronics so much, etc. Car jumped 7 times so far. Took to dealer 3 times (9/29 brakes, 12/9/20 & 1/2/21 for battery and brakes) so far and dealer even had to charge battery (1/21)! Unknown drain from somewhere. Every time happens have to have tail gate reprogrammed or not able to open.
