I bought a 2021 Ascent - Touring , lately there was an ever increasing amount of wind noise. It sounded like it was coming from the sunroof, but I couldn't see anything from the inside that looked out of place and there were no signs of water leaking. I finally looked up on the roof from the outside and the weather stripping along the back of the sunroof was coming out. The glue is thin, and didn't even stick to it anymore.. This is an ongoing issue. There are people people on the Subaru Ascent, Facebook Reddit forms that have said they are having the same issue..

Battery draining. Bought car from dealership preowned with 25k miles. Owned it for 3 weeks and so far -Battery dead, jumped it, good for a day then dead again. -took back to dealership, said bad battery, replaced it, good for a week and a half then dead again -scheduling to go to a subaru dealership for diagnoses Ive read about the DCM on these vehicles trying to connect to 3g towers continously even when the car is off. The 3g towers are no longer in use in the USA. Subaru should have a software update to remedy this issue but have not found that thus far. Just a lawsuit over this issue.

The vehicle has a parasitic battery draw. I purchased a new gel cell (Redtop) battery, the most powerful one that fits the car, and was reimbursed by Subaru. The car battery still goes totally dead after about one week, even with occasional driving. I have to carry a jump battery in case I am traveling to insure that I can get the car started when I stop.

The contact owns a 2021 Subaru Ascent. The contact received notification of NHTSA Campaign Number: 22V9070000 (Electrical System) however, the part to do the recall repair was not yet available. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and informed her that parts were available. The dealer was called back, and the contact was placed on a waiting list. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. Parts distribution disconnect.

THE MOON ROOF/SUNROOF HAS LEAKED NUMEROUS TIMES. THE DEALER HAS TRIED TO FIX IT ON THREE OCCASIONS. IT CONTINUES TO LEAK- IT LEAKS WATER INTO THE FRONT EYESIGHT CAMERAS CAUSING THEM TO NOT WORK & CUT OFF SPORADICALLY. THE WATER LEAKS INTO THE CAB CAUSING THE HEADLINER TO BE WET, THE FLOORBOARD AND THE ENTIRE CONSOLE AND CUP HOLDERS FILLS UP WITH WATER. I HAVE HAD IT AT THE DEALERSHIP ON THREE OCCASIONS DEC 2012 JAN 2021 NOV 11 2022 AND IT HAS NOW HAPPENED A 4 TH TIME ON NOV 15 2022 AND IS STILL NOT REPAIRED. I HAVE BEEN WITHOUT MY VEHICLE FOR 34 DAYS. IT HAS LESS THAN 18,000 MILES ON IT.

The battery constantly drains when the car is not in use for a very short time. It appears to be an electrical drain. I have already replaced the battery two times and the car has less than 15,000 miles. Apparently this is the same problem as in the 2016 - 2019 class action suit.

The battery died after 2 years and 15000 miles. I was with my whole family ( 2 months old, 2 and 4 years old) away from home. I was able to reach the dealership leaving my family in a store and they said that nothing was wrong with the battery. Next day the car wouldn’t start and they finally replaced the battery under my extended warranty. Today I discover that there is a class action settlement for older models of my car. I was advised to write a complain to you. Apparently they didn’t fix the problem with newer models either.

The battery went dead even though the car was parked in the garage and had been driven recently. AAA was called to jump start it. The vehicle only has 5k miles on it, so it shouldn’t be having battery problems. We are lucky this happened at home.

My mirror on my car has started melting. They told me it was a outside force, from a lighter. I told them it was electrical or something wrong from the inside of the mirror. There are forums recently posted up regarding this and Subaru has ignored them all claiming it is reflective light from the sun. That they can’t do anything about it. Others have replaced their mirrors 3 times now. This is a potential fire hazard and could be unsafe. They are not addressing this as it should be. https://www.thesubaruforums.com/threads/melting-side-view-mirror.12397/

After leaving liftgate open for a while, battery was dead. Learned from website that this was known issue for Subaru’s with automated liftgate. As i was camping with no cell signal, it was super difficult to get help and this could lead to the really big issue. This is the known issue for a while and I was shocked to Leane that Subaru did nothing to fix this.

AT 1667 MILES ON MY BRAND NEW SUBARU ASCENT THE BATTERY WAS COMPLETELY DRAINED WHILE MY WIFE WAS OUT SHOPPING. THE BATTERY NEEDED TO BE REPLACED. NO CHARGE TO ME, HOWEVER AT 1667 MILES THAT IS AN ISSUE. THERE IS A DEAD SUBARU ASCENT BATTERY CLUB THAT N FACEBOOK DEDICATED TO THIS ISSUE AND LAWYERS STARTING TO GET READY FOR CLASS ACTION LAW SUIT. VEHICLE WAS PARKED WHEN THIS HAPPENED. DEALER COULDN'T EXPLAIN WHAT HAPPENED.
