2021 SUBARU ASCENT Unknown Or Other Problems

2021 Subaru Ascent (VIN#***). Water found dripping down both second row seatbelts on multiple occasions during or following heavy rain, accumulated into mold growth on the carpet in front of second row seats to the front of the 3rd row seats (cargo area dry, front footwells dry). Authorized Subaru dealer technician report (dated 10/29/25 and 12/3/25 copy pasted into email) explicitly documents 'condensation build up on the interior of roof (seat belt area)' due to unlocated water intrusion. The dealer attributes this to 'leaf debris' in the front cowl area and rear hatch hinge despite the leak occurring at the rear C-pillar (and notably cargo area and front footwells showed no moisture making this physically impossible). Despite confirmed moisture exposure to critical passive restraint systems, the dealer relays that the manufacturer has issued a verbal-only warranty denial (stating no addl records exist aside from the initial technician report) and suggest...

The transmission on our 2021 Subaru Ascent is slipping and failing to accelerate, RPMs reving, and every issue indicator notification light is on. We took the car to our mechanic, then to the Subaru dealership service dept for diagnosis. A full transmission replacement is required plus associated repairs for a cost of $14,543.98. Service estimate attached. This repair is more than 2/3 of the value of the vehicle. This make/model and transmission type have documented problems and Subaru has previously issued an extended warranty on other model years for this same transmission issue. We are trying to communicate with the Subaru customer service but have had limited response due to the holidays and have not had a resolution yet in the past month.

Trunk would not open. Only way to open was to pop open the internal latch access port and switch the latch open with a screw driver. Trunk would not open with key fob, rear handle, or buttons on driver side dashboard.

The lane assist failed by over correcting while I have my hands on the steering wheel. It over corrects to the center lane when you are driving with normal behavior. This can cause a collision if it were to over correct while a car was there, this is also easily reproducible in my car.

Transmission needed a full replacement

Lift gate began malfunctioning going up and down on its ownthen dropped suddenly onto spouse's head. Now the lift gate does not open properly.

After 3 years the battery died completely and the car was unable to start, I replaced the battery with AAA and the next the day, it also died again. I was able to jump start the battery the next day and continued to use the vehicle. I have the battery for about a month and again the battery on the vehicle had drained where I was unable to start the car but I was able to jump start the car with a battery jump starter. There has been 3 occasions of battery just draining and I have a new battery installed. I called Subaru and they mentioned that there could be an issue with the back latch no closing which could drain the battery, however, the have confirmed that the back door does completely close and lock or it will just automatically come back up. I feel there is something...

2021 Subaru Ascent with 15,735 miles on it with the factory Falken tires. The tread and metal was showing and separating from the tires. 2 tires, original to the car off the lot. Tires should last 30-40-50 miles. The other 2 tires were labeled as a 4-5 category. The car did not steer to the left or right, no noise at all. If driving on the highway and 2 tires failed, I could have been injured, my passengers or another vehicle crash. This was very dangerous. In going to the Subaru website and seems hundreds of other customers had the same issue. Failing, inferior, defective Falken tires and alignment issues. I hope these tires don't fail and cause someone to lose their life.

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.

Windshield is extremely soft and cracks easily. In less than 1.5 years I've owned the car I've gotten 3 chips/cracks and now a 4th major one that requires a full replacement. No car previously owned ever had this issue, not even the previous Subaru. After searching online this seems to be a common problem in Subarus, as there was a class action suit for earlier models. Yes, car is currently available for inspection until repaired. Super soft windshield - if the windshield is broken completely on a highway, it's obviously a concern and a risk. Have not taken the car in yet, but will be to get it replaced.

April 25, 2022: The trunk/liftgate of the vehicle failed to detect an obstruction and closed without retracting when it came in contact with an individual's head. The impact caused a head injury, blackout, and concussion, and resulted in permanent damage to an individual (6' 2" - 190lbs). Subaru’s stated that an inspection of the vehicle was performed on May 19th and informed me that “the vehicle is operating as designed…and has met all federal specifications,” and that their inspection concluded that this is “no manufacturing defect.” Prior to the inspection, Subaru requested signed consent to inspect the vehicle's internal data which I provided. When I requested a copy of the report, Subaru informed me of their policy not to share this information despite the vehicle "operating as designed." One of the first things that we learn about computers is “Garbage in, garbage out.” My position is that if Subaru’s computers...

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/

The windshield cracked without impact.
