Subaru Legacy Reliability by YearBest & worst years, problems & recalls — NHTSA data

All electronic instrument panels failed to power on upon ignition. Vehicle was drive-able, but all key information provided by instrument panel was not available: such as actual speed, gear selection, engine RPMs, backup cameras. Additionally, infotainment system was not available either, so none of vehicle controls that reside on the displays were available. This condition persisted thru the length of drive.

While driving home after work on the interstate, I was quite startled to see a large popup on the vehicle's main screen; initially I thought it might be some sort of vehicle-problem, but it was a large advertisement for free access to SiriusXM for a limited time. The ad covered the screen and was quite jarring while driving in traffic. In order to close it, I pressed a red X in the upper corner. Such in-vehicle advertisements should NOT be presented while driving (actually, at any time).

Voice command in my 2023 legacy is not working. I can not speak into system to say call a person already entered without taking hands off steering wheel. Already reported to dealer & to corporate Subaru & it is a known issue. Reference # with corporate is 250620-1900992. This was reported to dealer in June 2025 when in for service & no fix has been noted other than Subaru is working on it? Feature built into car at purchase is thus useless & seems like a safety issue if I can’t use hands free when driving.

This issue started on the trip back from Nashville. Upon cold start in the morning the center console display won't start. This affected infotainment, climate, eyesight, cruise etc. The system didn't work during the entire trip of 3 5 hours and inability to operate climate control caused the car to build up fog on all windows reducing visibility significantly at times. Turning ignition off, lock-unlock sequences didn't help the issue. The system booted normally after it sat locked for few hours upon arrival. A visit to dealer didn't find any issues. The usual comment the car needed software update, which I couldn't verify.

Accorn fell on windshield. At 14,000 miles windshield cracked. Was driving approximately 35MPH

My wife is a petite woman, 4 feet 7 inches, 85pounds clothed. We bought the car March 29, 2023 and drove home, and the passenger airbag worked properly thru April 2. Behavior after that became erratic, passenger airbag sometimes on, sometimes not. Became more erratic and brought to dealer (Balise Subaru) April 12. Service technician reported system worked properly, no error codes. I asked Service manager to look at the car with my wife rather than a 180 pound technician sitting in it. He observed that with my wife in the passenger seat he would start and stop the car, and sometime the airbag was on, other times off even though she never moved or change position. He was going to check with Subaru, saying nothing in the system could be adjusted and it had a trigger weight of approximately 80.5 pounds. Erratic behavior became worse such that airbag was off 75% of the time. Tried various seat positions to no effect. Note: My wife sits 23 inches from the dashboard. On April 18 on a round trip to a doctor she weighed 84.6 pounds on a medical scale in normal indoor clothes, and wore a light coat (1.2 pounds) while in the car in both directions. The airbag was on the entire trip to the doctor, and off the entire trip home. Subaru responded she was so small and near trigger weight was the likely cause. Dealer did re zero the passenger seat, no change. Car has been at the dealer 3 times for this problem, and system has become somewhat less erratic such that the airbag is either on immediately or more often within 5 minutes of driving 50-60% of the time, yet my wife's weight has held steady. Two patterns I have found: Temperature sensitivity: more consistent when temp is in the 40s or 60s, worse in the 50s, and variable otherwise. Having the AC on seems to help so I'm wondering if the control unit or seat sensors are overheating, also high lateral forces on on-ramps will turn the airbag on. I also suspect the seat sensors lack precision and weigh my wife erratically.

The contact owns a 2023 Subaru Legacy. The contact stated that when she entered her vehicle, she noticed that there was a crack in the windshield down by windshield wiper on the driver's side. The contact stated that the crack had begun to expand up the windshield and stopped approximately 4 inches from the where the windshield joins the vehicle subframe. The contact stated that this was the second windshield she had installed. The contact stated that dealer told her the first replacement had been from road debris. The contact stated she never had no windshield strikes in the five weeks she had owned the vehicle. The contact had taken the vehicle to a local glass shop where it was diagnosed and determined that the windshield needed to be replaced. The vehicle had been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 2,000.

Vehicle: 2021 Subaru Legacy Base 2.5i Mileage:~65,000 miles My engine suddenly began making loud internal knocking/tapping noises with no warning lights, no overheating, and no prior symptoms. The vehicle immediately became unsafe to operate. I had it towed to a Subaru dealership, where technicians confirmed the noise was coming from inside the engine and recommended a full engine replacement. The failure happened without any warning indicators, misfires, overheating, or oil pressure warnings. All diagnostics (including compression and leakdown) were clean, and the vehicle has been properly maintained. Subaru of America acknowledged the internal failure but only offered $1,000 goodwill toward a multi‑thousand‑dollar engine replacement. This appears to be a premature internal engine failure on the FB25 engine, which may indicate a defect. A sudden internal engine failure at highway speeds could lead to loss of power, stalling, or inability to accelerate, creating a safety hazard for the driver and surrounding traffic. I am filing this complaint because this type of unexpected internal engine failure at relatively low mileage may represent a pattern and should be tracked for potential investigation.

See attached document for complaint.

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 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.
