I have had this happen several times on my 2021 Outback and my 2013 Outback. The dealership has never been able to recreate this issue. I will be driving (gear in D) and it randomly shifts to 1st or 2nd gear. I have been in a parking lot when it has happened or entering the interstate. I notice it because I hear the engine roar and look down to see it shifted gears. I only use D so this should never happen.

The speed control (adaptive) doesn't work. The interior heater doesn't work. Several lights including the 'check engine' light come on the dash. The lane departure system doesn't work. (It appears the thermo control value subassembly may be at fault.) The car has approximately 25K miles on it.

I was driving when I heard a loud explosion sound. I first thought a rock or gunshot hit my car and pulled over to examine my car. I checked all around the car and didn't notice any damage on the side of my car but then I noticed that my sunroof was shattered. The glass was pushed outward which meant that it was not hit by an object. Luckily, my interior cover to my sunroof was closed at the time so I was not harmed.

Oct 14, 2024Visibility & wipers

Since owning this vehicle, we have replaced the windshield at least once a year. The first due to a 1/16th inch chip that evolved into a 10 inch crack over the course of a day. The second was a crack from driver side pillar that appeared overnight, no chips prior. Third was a 8" crack from passenger pillar that appeared overnight while garage parked, after a day, it grew to reach the center of the windshield. I think it's unacceptable that windshields can just crack overnight less than a year after install. It's beyond concerning knowing that our windshield could crack at anytime, or that superficial chips must be taken care of IMMEDIATELY or we run the risk of replacing the entire windshield.

Battery keeps draining if car isn't driven for a few days battery is drained to point of it being dead, cannot get into car, will not start, leaves you stranded. This is the fourth time this year, dealer checks it out tells me nothing is wrong. I have read many problems with parasitic battery drain with subaru's even that the alternator is programed not to fully charge the battery to save gas. getting tired of the issue to the point where I am thinking of selling the car and finding something that will not leave me stranded. This time when I checked the battery voltage it was 5.80 volts and .29 amps.

Battery drains quickly and renders the car inoperable. Possibly due to Controller Area Network (CAN) not entering sleep mode when vehicle is not being used resulting in a parasitic battery drain.

Aug 29, 2024SteeringElectrical systemBody & structure

The car flashed “eye sight off” before flickering and shutting off while I was braking at a stop light. I tried putting my car into park and then turning it off and restarting it but it would not turn back on. I tried this a few more times but I was in the middle lane of a heavily trafficked street. The steering wheel was locked and I was not able to immediately remove it from the road and maybe an hour later it was able to be shifted into neutral and moved out of the street. However, it would still not turn on and when I did open my power gate, the gate would not secure closed. I took it to the dealership that I purchased it at and where it is also regularly serviced (with the last service date only over one week ago,) and they were not able to determine what happened but instead mentioned that my car had no internal data of any errors occurring and that the car was able to be started when they serviced it. I took a picture of the dash as it was flashing with all of the error codes and submitted that to the tech that was working on my car, but they asked me if I’d had someone “clear my codes” which is not something I’m familiar with or even capable of doing- I don’t even know anyone that would be capable of doing that for me. The whole ordeal cost me a day of work and now my peace of mind as I am unsure of if this may happen again and now I am worried it may happen while my kids are in the car. I’ve had similar issues with my center console messing up but nothing as urgent as my whole car shutting down and my steering wheel locking in the middle of traffic.

Today while waiting at a stop light the auto start stop engaged. When the light went green I put my foot on the gas and the vehicle stalled. The car was on but not running, several alarms were on the dashboard. I had to put the car in park, turn it off and then restart the car. This is a repeated issue and has been going on at least once a month since we purchased the car in 2021. We've brought it to the dealer and they said there was nothing wrong because there was no OBD code. I have checked myself and I have not found any code. This is extremely unsafe

2021 Subaru Outback Limited | ~13000 miles | Component: Battery | Car suddenly stopped and ALL warning lights started flashing at a busy traffic signal, while I was waiting to take a left turn (lucky to have escaped safely from that situation). I had to turn the car off and restart it. 2 days later, the car would not start at all. Tried jumping it multiple time in vain. Had to tow the car to the nearest Subaru service center. Technician ran a diagnostic and concluded that the battery was not holding any charge at all and it was deemed faulty. Reading many posts on reddit and other forums of many Subaru owners facing the same issue from older (2015) to newer models. Many of them also complained of Parasitic drain on the battery due to faulty DCM on Starlink. Note: there was no warning lights/messages or any other symptom before this. This was a Subaru certified pre-owned car that went through a 152 point inspection in 2023.

Driving home on a farm road, a truck passed by, picking up a pebble that hit my windshield. On my other vehicles, that same impact would leave a chip on the windshield but due to its light thickness, it immediately formed a long crack that is continually growing in size as it is currently my daily commuter to work. That was a huge bummer given I had purchased it recently and it didn't have any blemishes on the windshield. The pebble hit the upper driver side part which led the crack to form out toward the roof and is going diagonal to the passenger side below the visor.

Front windshield on my 2021 outback has numerous large cracks for no reason. This is a known issue via Google and class action law suits for windshields. This is a safety issue and needs to be addressed. I emailed Subaru and filed a complaint with them, Case#240708-220236. Asking them to replace windshield with new one that won't crack like this one. i have photos if needed.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Subaru Outback Wilderness verdict →
