2020 Subaru Ascent

The CVT transmission has failed and been replaced three times despite proper maintenance. Subaru has replaced the transmission multiple times under warranty, but the failure continues to recur. •First CVT replacement at 50,542 miles •Second CVT replacement at 88,175 miles •Third CVT replacement at 92,832 miles This shows repeat failure, not wear-and-tear. It is a safety risk: The vehicle hesitates and loses power intermittently, which creates a safety risk when accelerating or merging into traffic. The most recent replacement is incorrectly listed as pan replacement.

The contact owns a 2020 Subaru Ascent. The contact stated that while depressing the accelerator pedal to make a turn, the vehicle hesitated to respond. There was no warning light illuminated. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 61,900.

My 2020 Subaru Ascent experienced a sudden failure of critical safety systems due to CVT fluid leaking through the transmission pressure switch into multiple electrical components. This fluid leak damaged several wire harnesses and the Engine Control Module (ECM). The check engine light came on and all Eyesight safety features disabled. Subaru has confirmed this will cost over $9,400 to repair. This issue appears to be related to known Subaru Technical Service Bulletins, including TSB 16-103-16R and TSB 02-170-17R, and matches the description in NHTSA Campaign WUV-07. Subaru of America has refused to fully cover the repair, even though my car is well maintained, has only 54,000 miles, and is just 4 months outside the powertrain warranty. This is not normal wear—it’s a serious defect that causes electronic failure and disables safety systems while driving.

Ever since our car went in for re-programing CVT drive chain it progressively has been having a problem of something slipping in drive and in cruise control. feels like a loss of power and a feeling chatter from transmission. Now when you put it in drive it makes a jerking noise. the thing is that we never had this problem until it went in for this recall. it's been back twice and they claim they can't find any problem but continues to get worse. it happens every time we drive it . just returned a 700 mile trip and it's very annoying. Also we do have an extended warranty.

While driving the vehicle between 30 - 40 mph, the vehicle will intermittently studder. I have mentioned this issue multiple times to the dealership and they have attempted to fix the issue but the problem still continues. The issue is occurring more frequently and I’m concerned this may create additional engine/powertrain problems down the road.

The contact owns a 2020 Subaru Ascent. The contact stated that while operating the vehicle, the transmission malfunctioned, and the vehicle would not properly accelerate. The vehicle was taken to the local dealer who serviced the rear differential but later the failure reoccurred. The vehicle was taken back to the local dealer to be diagnosed, and it was determined that the transmission was faulty and needed to be replaced. The transmission was replaced. No further information was available. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 106,100.

Bolt holding the driveshaft support bracket backed out causing driveshaft to come out. This is a known issue with the 2019 and 2022 Subaru Ascents and have active service advisories but Subaru of America does not recognize it for the 2020 models even know it is also happening in the 2020 vehicles. If the driveshaft would have came out at a high speed it could have caused a crash. Based on the research the bolts do not hold the torque from the factory due to a bolt manufacturing issue and slowly back out after time unknown to the driver. Subaru is not recognizing the problem, so they are not notifying the 2020 owners of the problem, instead they are offering a 50% payment on the repairs as a goodwill payment to offset the cost since it is not a warranty issue. I had had my car in for oil changes in the past and the dealership did not know to check for the tightness of the bolts as there were no service advisories. There should be a recall for this problem before someone dies in a crash caused by this problem.

When driving, Ascent sudders while under normal highway conditions. Has had all 4 recalls completed but this specific event has been consistently present even after each recall was completed. Now that Ascent is out of powertrain period, Subaru of America acknowledged transmission finally needs complete replacement but only offering portion as a one time offer.

The contact owns a 2020 Subaru Ascent. The contact stated while driving 30 MPH, the transmission was slipping, and there was a loud sound coming from the vehicle. The contact stated that the vehicle lost motive power while accelerating. The contact was unsure if any warning lights were illuminated. The contact pulled over and left the vehicle for several hours. Upon return to the vehicle, the contact stated that the vehicle drove normally. The vehicle was taken to the dealer and an unknown module was reprogrammed; however, the failure recurred several times. The vehicle was taken back to the dealer and a diagnostic test was performed; however, the dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure and stated that if the failure could not be duplicated the vehicle could not be repaired. The approximate failure mileage was 25,000.
