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.
WE PURCHASED A NEW VEHICLE AND WITHIN 400 MILES THE BATTERY WAS COMPLETELY DEAD. NO LIGHTS WERE LEFT ON OR NOR WAS THERE ANY EXTERNAL DRAIN ON THE BATTERY. THE VEHICLE WAS STATIONARY AND PARKED IN OUR GARAGE.

A LARGE CRACK SUDDENLY APPEARED ON THE WINDSHIELD OF MY 2020 ASCENT, AND EXPANDED RAPIDLY OVER THE COURSE OF A FEW HOURS. I PURCHASED THE VEHICLE NEW IN JANUARY 2020. SUBARU WILL NOT COVER THE WINDSHIELD UNDER WARRANTY. THE COST TO REPLACE THE WINDSHIELD AND RE-CALIBRATE THE EYESIGHT SENSORS IS OVER $1,000 THROUGH SAFELITE. I'M CONCERNED THAT HAVING AN OUTSIDE COMPANY RE-CALIBRATE THE SENSORS WILL VOID THE WARRANTY, AND THE DEALERSHIP COULD NOT PROVIDE ANY CLARIFICATION. MY DEALERSHIP CANNOT REPLACE THE WINDSHIELD (AS THEY'VE INDICATED THIS MUST BE DONE BY A THIRD PARTY), AND CANNOT RE-CALIBRATE THE SENSORS FOR OVER A WEEK. THERE IS NO REASON FOR MY WINDSHIELD TO HAVE SUCH A LARGE CRACK, AS THERE ARE NO CHIPS VISIBLE AND I DO NOT RECALL ANYTHING STRIKING MY WINDSHIELD RECENTLY. *TR
