Water intrusion occurred inside the vehicle, resulting in extensive mold contamination throughout the interior, including the seats, front and rear carpets, and a child’s car seat. The source of the water intrusion has not been identified. The vehicle was taken to an authorized Subaru retailer, which confirmed in writing that water was present inside the vehicle and that mold was covering interior surfaces, including the child’s car seat. The only diagnostic test performed was a car wash to check for a sunroof leak, which did not replicate the issue. The retailer indicated that further diagnostic work would require significant interior disassembly and cleaning at the owner’s expense before the source of the leak can be determined. The manufacturer was contacted regarding this issue and declined assistance, citing “lack of required maintenance.” The specific maintenance and its relationship to the water intrusion have not been identified, and the source of the leak has not yet been diagnosed. The retailer also stated that technicians would not enter the vehicle due to the extent of the mold contamination. As a result, standard recall repairs have not been performed while the vehicle remains in this condition. A dealership technician also documented in a recorded inspection that water was present beneath the carpet, that the source of the leak could not be identified without further disassembly, and that the extent of mold contamination created an unsafe working environment. This condition creates a potential health and safety concern due to mold exposure inside the passenger cabin, particularly for a child occupant. In addition, excessive interior moisture has caused window fogging, which may impair visibility while driving. No warning lights or prior indicators were observed before the issue was discovered. The problem has been confirmed by a Subaru retailer. The vehicle remains available for inspection.

I can’t say what caused the huge crack in the sunroof bc there is no chips on the outside and no chips or breaking point on the inside. We went to get in the car and open up the sunroof and it has a huge crack that is a known issue if you look it up online. So far we haven’t been able to get it fixed bc of the amount of money it cost to have it replaced and it can’t be done by anymore but the dealer as safelight won’t touch sunroofs. It appears that a weak glass was installed and that’s unfortunate too bc they have no intention on fixing this for us.

2020 Subaru Ascent Premium.. Rear lift gate at times will not open electronically, and sounds an “alarm” locking the mechanism which prevents it from being opened. The alarm and lockout does not stop until the battery is disconnected. The first time this occurred was at a Subaru Dealership, the second time was at a location where it was necessary for me to go home to my shop to get the battery disconnected.

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.

FOUND AROUND 1 INCH OF WATER SETTING UNDER DRIVER'S SEAT OF OUR 2020 SUBARU ASCENT TOURING, WITH ONLY 2500 MILES ON IT, AFTER THE CAR HAD BEEN SITTING FOR DAYS WITH RAIN STORMS. WIFE NOTICES A SLOSHING SOUND WHILE SHE DROVE IT 1 MILE AND BACK HOME. TOOK IT TO THE DEALER AND THEY KEPT IT, BUT COULDN'T INITIALLY FIND THE LEAK. THE VEHICLE HAD A COMPLAINT OF A WATER LEAK PRIOR, WITH NO DEALER ACTION. AFTER TWO WEEKS OF LOOKING, THE DEALER SAID IT WAS A MISSING OR POORLY INSTALLED GROMMET ON THE FIRE WALL AROUND THE MAIN WIRING HARNESS, WHICH ALLOWED WATER TO FLOW INTO THE PASSENGER COMPARTMENT. THEY ARE ATTEMPTING TO REPLACE THE ENTIRE CARPET AND PUTTING IN A NEW WIRING HARNESS, WHICH WOULD INDICATE A POTENTIAL FOR MOLD AND ELECTRICAL ISSUES DUE TO POOR GROMMET INSTALLATION ON THE FIREWALL. IF THIS VEHICLE HAD NOT BEEN SITTING OUTSIDE, THE ISSUE WOULDN'T OF BEEN FOUND FOR A LONG TIME, CAUSING MOLD AND POTENTIAL ELECTRICAL FIRES IN THE PASSENGER COMPARTMENT. HOPEFULLY, THIS WILL SAVE LIVES AND KEEP PEOPLE HEALTHY, IF THEY CHECK THEIR FIREWALL GROMMETS FOR POOR INSTALLATION.
