Electrical system

37 reports2 crashes2 fires
“I have had several battery issues that I just believed to be bad luck and would get a new battery under warranty but it has gotten worse lately. It led me to look online and I notice I am not nearly the only one as this complaint has been brought up my numerous people. It is in regards to my 2015 Subaru legacy and how I’m not certain if my car will start if I make a few short trips where I’m “in and out” of the car more than 3 times in a short period of time. There is definitely a parasitic draw issue from the vehicle and it is a safety concern in not knowing if your vehicle is going to start or if you’ll need a jump or worse be stranded. With the amount of complaints on this issue I would have thought there would be a recall. I know there are safety bulletins but nothing that the dealer or Subaru themselves will address. I have also signed up for the battery settlement case but have not heard back in regards to this. I am really wanting to know if there is a solution because I’ve read a lot of reviews where this is happening in newer models also. It needs to be addressed and a resolution should be offered because it is happening to A LOT of Subarus. My other…”

Visibility/wiper

36 reports
“My windshield cracked when I used the washer fluid. It cracked from the bottom where the VIN number is and continued across the windshield. I went to the Subaru dealer in Portage Indiana, to have it fixed under the extended warranty I received from Subaru for faulty windshields the dealer told me that it cracked in the wrong spot, and would not be covered. The dealer agreed that the windshield crack was not from any type of impact.”

Engine

“I am reporting a Sudden Unintended Deceleration event in my Subaru. The vehicle grinded to a halt without driver input. The car stopped in the left lane of a major highway. We put on our hazards and called the state police for help. They were unable to get to us in time. We were hit from the rear. The car's failure created a stationary hazard that led to a high-speed rear-end collision by a Jeep and truck which caused the car to do a 360-degree spin.”

Power train

15 reports1 crash1 related recall
“2015 Subaru Legacy 2.5i, approximately 48,000 miles. CVT transmission failed suddenly with no prior warning signs. Vehicle was exclusively dealer-serviced for its entire life. While driving, the transmission began shuddering, slipping, and making metallic grinding noises. Vehicle could barely climb a small ramp and was locked in limp mode, making it unsafe to operate in traffic. Diagnostic codes P0841, P0700, and C1431 were stored. Authorized Subaru dealer confirmed the failure. Technician stated the valve body likely failed first — a known defect per Subaru TSB 16-107-17R — which then caused the CVT chain to slip. Dealer quoted $11,000 for a remanufactured CVT replacement. Service representative stated she had never seen a transmission need replacement at such low mileage. No warning lamps or symptoms existed prior to sudden onset. CVT fluid was never changed, consistent with the manufacturer's U.S. maintenance schedule. This vehicle falls under Subaru's CVT Warranty Extension covering 2010-2015 Legacy models due to known defects. Vehicle is well under the 100,000-mile limit but approximately 13 months past the 10-year time limit. I opened a case with Subaru…”

“2015 Subaru Legacy 2.5 engine. Fuel gauge is inaccurate. My daughter was on the highway when it ran out of fuel. Had car towed to a independent shop. They said that the fuel gauges is a problem for Subaru 's and that they had seen it before on other Subaru's.”

“Subaru sudden acceleration – Garage Accident [XXX] [XXX] – before noon, wet, rainy day: [XXX] returning from grocery shopping - car suddenly accelerated from near stop as she was about to enter garage, the car hit the garage brick wall. When she put her foot on the brake, the car suddenly accelerated. I have security video showing this sudden acceleration (.mp4, nhtsa doesn't accept).
