2020 Subaru Ascent Reliability Report

Battery life issue

My car did not start and the anti-theft light came on the dashboard (the one with the car and lock symbol). I know battery issues have been a known problem with my subaru model and i bought the car in oct 2019 so it's been less than 3 years. The battery should not be dying this quickly. I had to get a jump start to get the car on. After a few hours, i tried starting it again and it did not work. I was told I'd need to get my battery replaced.

2020 Subaru Ascent that I purchased in November of 2019 had original brand new battery replaced in July of 2020 The “ new battery “ is now defective and car needs to be jump started. Defective battery or defective electrical system?

The car's braking system has a severe shudder at times, as well as a loud noise, and seems hesitant with stopping abilities. The dealership confirmed the issues, turned the rotors within the first year of ownership. Problem did not improve. The front brakes and rotors were replaced at 24000 miles. Within a couple months problem was occurring again. Dealership said they couldn't duplicate the issues. Had it back in again at 50000 miles (3 years old) and said they need replaced again on front, and now the rear as well.

The emergency brake occasionally comes on for no apparent reason. It has happened multiple times before but, never while driving until today. The button appeared to be stuck when I went to disengage it as well which made no sense. There was nothing in the way for it to get stuck. Upon further research in the Subaru forums it appears ours is not the only one to have experienced this. This leads me to believe there may be an unknown issue.

Transmission failure, chugging while driving on the road then slowed down in middle of the intersection, won’t accelerate which is a unsafe situation. It says “check engine”, “break, “eyesight disabled”, “at oil temp” and “transmission”. The speed was stuck to 20mph and engine eas loud. Smelled like something was burning too

TL* THE CONTACT OWNS A 2020 SUBARU ASCENT. THE CONTACT STATED SHE NOTICIED TINY DOTS ON THE WINDSHIELD, WHICH OBSTRUCTED HER VIEW WHILE DRIVING. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER CAMELBACK VW (1499 E CAMELBACK RD, PHOENIX, AZ 85014, (602) 648-9181) AND THE MECHANIC WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 1,000.

I GOT IN MY CAR AND TOOK THE SUN SHADE OUT OF MY WINDSHIELD AND FOUND A LARGE CRACK ACROSS IT. THE LAST TIME IT WAS DRIVEN (2 DAYS AGO) THERE WAS NO CRACK. THE CAR WAS PARKED IN MY DRIVEWAY. *TR

The contact owns a 2020 Subaru Ascent. The contact stated that he parked the vehicle in the parking garage overnight and when he went to get into the vehicle the next morning, he noticed that the windshield was cracked. The vehicle was taken to the dealer and the dealer was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 60,000.

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.

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

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 was driving and I got check engine light and all safety features disabled while I was in the freeway, luckily I was able to drive to nearby Subaru dealer for inspection and I found out that there was a recall on the engine for this vehicle and when I contacted the manufacturer they asked me to take it for diagnostics and I did that at a Subaru retailer, but the case manager told me that this recall is being completed for the previous owner of the vehicle and cannot help me with anything, which was never disclosed when I was buying the vehicle.

Car has 82,000 miles, has been maintained and requires an engine replacement due to 'Sludge'. Reading a lot of forums that indicate this is a common situation with this make and model and likely due to manufacturer's defects.

Unknown PCV valve failure caused catastrophic engine failure on interstate highway (70 mph speed limit). Luckily there was room to pull to the side and no one got hurt. This part was recalled in 2019 models due to possible loss of control from engine failure. Dealer tore down engine to determine cause for possible warranty coverage and found the PCV valve was the cause of engine failure. There were no warning lights or indications of any problems before this.

Car is making loud noises while going over uneven roads. Only have 64,000 miles on it and I need to replace the struts.

The contact owns a 2020 Subaru Ascent. The contact stated that while driving at an undisclosed speed, there was an abnormal rumbling sound coming from the undercarriage while driving over bumps in the roadway. No warning light was illuminated. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the front struts had failed and needed to be replaced. The contact related the failure to TSB: 059024. The vehicle was not diagnosed. The manufacturer was not made aware of the failure. The failure mileage was unknown.

Extreme rattle/clunking driving over bumps especially on dirt roads. Seems to be many people are having this issue. I know of another co worker who has a 2020 ascent making the same noise. Apparently there is a strut issue

UNINTENDED ACCELERATION - CAR WENT THROUGH AUTOMATIC CAR WAS WITH ENGINE RUNNING AND IN NEUTRAL. AFTER WASH WAS COMPLETED CAR WAS PLACED IN DRIVE AND I VERY LIGHTLY TOUCHED ACCELERATOR PEDAL. CAR LURCHED FORWARD AS THOUGH THE ACCELERATOR WAS FLOORED. REMOVED FOOT FROM ACCELERATOR, ENGINE WAS CONTINUING TO RACE AS CAR CONTINUED TO PICK UP SPEED AND HEADED OUT ONTO BUSY HIGHWAY. THE EXIT FROM THE CAR WASH WAS PERPENDICULAR TO THE HIGHWAY QUICKLY I STEPPED AS FORCEFULLY AS POSSIBLE ON THE BRAKE PEDAL AND SUBSEQUENTLY BROUGHT CAR TO A STOP. A VERY CLOSE CALL.

RAW FUEL SMELL COMING THROUGH VENTS WHEN OUTSIDE AIR IS BEING USED. MORE OFTEN THIS OCCURS WHEN ENGINE IS WARM AND HAS BEEN RESTARTED (I.E. SHORT TRIP). CAN EXPERIENCE THE SMELL WHEN THE CAR IS STATIONARY OR IN MOTION. SMELL IS ENOUGH TO CAUSE HEADACHE. DEALER COULDN'T REPLICATE BUT THIS HAPPENED AS SOON AS I PICKED UP THE CAR FROM THE DEALER.

I was almost in two accidents. Back on July 26,2021 I reported to the dealer that the car almost stalled twice, when I am coming to a yield or slowing down and then you accelerate The car has no power. You have to try to pull over before you get hit from behind. Then you step on the gas and it goes again (it does not completely stall) I did not know of any recall on the car but in the October issue of consumers reports it said they have a problem with the fuel pump It sounded like my same problem. I went back to the dealer on 10/14/2021 they went with me for a road test of course it did not happen. They said they cant do anything because my vin no. is not on recall. They can not find anything wrong with the car. Also, I feel the car hesitates when you step on the gas. They say no its normal. recall No 21v58700 7/28/2021 -- subaru recall no WRG-21
