2021 Subaru Legacy Owner Complaints

ON JANUARY 7, 2020 AT APPROXIMATELY 8AM, I WAS DRIVING MY CAR WHICH HAD BEEN WARMED UP AND DRIVING FOR APPROXIMATELY 15-20 MINUTES WHEN MY WINDSHIELD SPONTANEOUSLY CRACKED ON THE DRIVERS SIDE ABOUT 8 INCHES OFF CENTER. THERE WAS NO VEHICLE IN FRONT OF ME AT THE TIME AND NO VISIBLE OR AUDIBLE DEBRIS THAT COULD HAVE STRUCK THE WINDSHIELD. THE CRACK WAS ABOUT 8 INCHES LONG AND RAN VERTICALLY UP THE WINDSHIELD. FURTHER INSPECTION SHOWED THAT THE CRACK APPEARS TO HAVE STARTED BELOW THE WINDSHIELD WIPER WHERE THE GLASS MEETS THE PLASTIC, A LOCATION WHICH WOULD MAKE IT NEARLY IMPOSSIBLE FOR ANY DEBRIS TO MAKE CONTACT WITH THE WINDSHIELD. THE CRACK HAS NOW SPREAD TO ABOUT 14 INCHES LONG AND NOW RUNNING DIAGONALLY TOWARDS THE PASSENGER SIDE. WEATHER WAS ABOUT 30 AND SUNNY.

recall not fixed yet, what happens if a car hits me & the passenger airbags don’t work? unsafe, doesn’t seem like it’s being fixed in a timely manner

There seems to be an issue with the infotainment system. The system will randomly turn off which also turns off the safety features. I would like to associate this while CarPlay is in use, but I have witnessed it happen without CarPlay. Subaru has already replaced the head unit under warranty, but the problem continues. For the cost of the car, this should not be an issue.

Battery died completely, left me stranded at a gas station. I had to call and get a jump. I've had the car 9 weeks, it only has 690 miles on it. No warning lights prior, did notice a slightly longer crank a couple days prior. I was told by the dealer that I don't drive enough, and I should keep my key at least 30 feet away when the keys are in the house, because that can silently drain the battery. I had not left any lights on or had done anything to drain the battery prior to this occurring. I drove to the gas station with no problem, upon restarting after getting gas, no power, car was dead. I couldn't even move the shifter knob into neutral.

Windshield spontaneously cracked while using defrost function on 9/9/2021. Crack started from bottom center of windshield, at the ceramic defrost line, below rubber seal. Crack approximately 6 inches long. Called Subaru within minutes and directed to take to dealership to have photo taken and submitted to Subaru for warranty work. Visited dealership and photos taken on 9/13/2021. Have been told by dealership multiple times still waiting on Subaru to approve the warranty work. Since then the crack has continued to spread and now goes up approximately 2/3rd of the windshield bottom towards top.

The component that failed is the windshield. The windshield has a 14 inch stress crack. The crack suddenly appeared, there was no impact. The crack interferes with the Subaru Eyesight Driver Assistance. The Subaru Eyesight Driver Assistance could malfunction while driving. The integrity of the windshield has been compromised. I brought the car to the Subaru dealership and they said it was not covered under warranty even though the car only has 6,000 miles on it. The Subaru dealership said they took pictures of the windshield and submitted them to Subaru of America. Subaru of America will not replace the windshield. According to Subaru when the windshield is replaced the Eyesight Driver Assistance must be recalibrated adding an additional expense.

The car's AEB system keeps mistaking steam from the street (such as sewer covers or construction sites) for a physical object and will activate. It has stopped my car in the middle of the street two days ago (5/31/22) and I was almost rear-ended by the car behind me. The warning system will also engage for no reason in most city driving conditions when there is no danger. It mistakes merging with cars with an imminent crash. I do not trust the system and now disable it whenever I drive as it is more likely to cause an accident than to prevent one. This has been a problem since I purchased the car. I contacted the dealer on 5/31/22 but have not heard back.

After shifting my car into reverse, I slowly started removing my foot from the brake pedal. At this time, the car started rapidly accelerating backwards so I put pressure back on the brake pedal to stop the car. When doing so, the ABS light came on my dashboard, I heard a griding sound like the car was still trying to accelerate, and there was a loud constant beep. I was able to shift the car into neutral and then into park to stop the car and then turned the car off. I contacted the dealership about the issue, but have not yet been able to further investigate or bring it into the dealership.

CVT Transmission Failure. Failure occurred at approximately 66,706 miles on 5/16/25. The Check Engine and AT Temp lights appeared in the instrument cluster. The driving conditions when this happened were a safety concern. First, the vehicle would crawl, shutter, and almost stall with high RPMs when attempting to climb a hill. Second, on a level surface at any given time the vehicle would not respond then lunge forward unexpectedly. The vehicle was inspected by a Subaru Dealership and the diagnosis was "Internal failure of transmission". The transmission needs to be replaced. The same driving conditions and error codes were experienced by an AAMCO Transmission repair facility. The diagnosis was codes P0843 and P0867 present prompting the transmission to be replaced. This repair was completed on 6/4/25. The failed transmission is no longer available.

Car intermittently will studder and not go into first gear or go into second gear dangerously having car bog down and almost stall and then it violently downshifts having car RMP Hague go very high then slip and have no power to wheels and then a few seconds later go into second gear violently taking off again. Have tried taking issue to dealer but won’t even look unless check engine light comes on. Which it sometimes will for this issue and will shut back off before my short drive to dealership. Very frustrated especially being my first new car paying monthly to have this problem

The contact owns a 2021 Subaru Legacy. The contact stated that while his wife was reversing out of the garage, the rearview camera froze. There was no warning light illuminated. The contact’s wife was able to reset the rearview camera with the assistance of his daughter who looked up the information on the internet. The vehicle was taken to the dealer who diagnosed that no issues were found. The contact stated that the failure reoccurred several times while driving. The vehicle was taken to the dealer who completed a 504-software update; however, the failure reoccurred twice while the contact was driving from the dealer to his residence. The vehicle was taken back to the dealer who informed the contact that they could not duplicate the failure. The manufacturer was notified of the failure and informed the contact that they would either ship a head unit to the dealer for the repair of the vehicle or they would buy back the vehicle. The manufacturer followed up with the contact and informed him that they would not assist as the dealer was unable to duplicate the failure.

The trunk does not stay open leading to sudden closing on body and head for anyone trying to use the trunk. Leading to a concussion and multiple injuries. Dealership said to place a complaint as there has not yet been a recall for this issue. There is no warning prior to this issue occurring.

The buckle stopped working without cause. Car is only a couple years old and my child attempted to buckle themselves only to find out it didn't lock after trying to buckle in. I took car to subaru dealership and was told that they had no idea why it stopped working and it was not repairable. They attempted to fix it but couldn't figure it out. Thus I could not use this seat in my car due to the danger of not being able to have a passenger buckled. This is scary as there was no reason that the belt no longer buckled and concerns me that the other buckles may be defective, especially if we were to get into a car accident knowing that there's a chance that the buckle may not work.

ODS sensor recall still not fixed/remedy available, used heat for first time since i purchased the car, minor cracks in the windshield, car radio/monitors randomly go black, reverse camera won’t work, restarts on there own after a while

A Recall was issued Mar 22, 2024 for a dangerous safety issue. AN AIR BAG That Does NOT Deploy During A Crash CAN Increase THE Risk OF Injury. Remedy Dealers Will Replace THE ODS Sensors ON THE Front Passenger Seat, Free OF Charge. Interim Letters Informing Owners OF THE Safety Risk Were Mailed MAY 17, 2024. Owners Will Receive A Second Letter Once THE Remedy IS Available. Owners MAY Contact Subaru Customer Service AT 1-844-373-6614. Subaru's Number FOR This Recall IS Wra-24. NHTSA issued their Recall for this problem. NHTSA Recall Number24V227000 Recall Status Recall Incomplete, remedy not yet available Now 8 months later Subaru drivers are still forced to drive around with this dangerous defect. This is totally unacceptable, irresponsible and local Subaru dealers have received no part for this repair and have not idea when they will ever get them. NHTSA needs to step in and get answers from Subaru and issue notices to owners with this problem of the danger involved if there is a crash and their passenger is killed because of this delay

Subaru has released a service bulletin regarding concerns with the Thermo Control Valve in specific vehicles. Unfortunately, individuals with vehicles bearing a rebuilt title, including myself, are required to cover expenses exceeding $2,000 out of their own pockets. Despite evidence indicating that the issue with the engine area is unrelated to the vehicle's rebuilt title, Subaru has chosen not to initiate a recall. This unequal treatment of titled vehicle owners is unjust, especially considering that these vehicles have passed all necessary local inspections and regulations to be deemed roadworthy. All vehicles falling within the designated mileage and age parameters should qualify for assistance. It is my belief that a recall must be issued, as this is a mechanical flaw present since the vehicle's initial manufacturing. In the accompanying service bulletin, Subaru acknowledges fault by stating that they have developed a more reliable and durable component. A P26A3 check engine light code.

The contact owns a 2021 Subaru Legacy. The contact stated that while driving at various speeds during colder weather, the heater failed to operate as intended. Additionally, the Eyesight system was inoperable. The check engine and other unknown warning lights were displayed. In addition, the contact stated that the engine failed to warm up as intended after being started, and the engine temperature was 107°F, which was below the normal engine temperature of 200°F. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the Thermal Control Valve needed to be replaced. The contact related the failure to Technical Service Bulletin: 09-119-24; however, the vehicle was not repaired because the vehicle had a Salvaged Title. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.
