Visibility/wiper, Jul 19, 2022
Windshield spontaneously cracked while parked. I parked the vehicle around 3pm and at that time, no crack was present. I left the house at 5:30pm and in that 2.5 hours, a 12-18 inch crack appeared. There’s no visible impact point and it starts from the bottom edge of the glass on the passenger side. I have not brought it to the dealer yet as I’m working through a claim center for windshield coverage. This is the third time since I purchased the vehicle (May of 2021) that the windshield has cracked.
Electrical system, Engine, Jul 18, 2022, fire
The engine block of our car caught fire while it was parked and turned off. It melted the engine and hood of the car, totaling it. Thankfully, we were not in the vehicle when the incident occurred, so no one was injured. At the time of the incident, our car was parked outside our apartment building under a low-hanging tree, which was burned in the fire. Had a neighbor not noticed and called 911, the fire may have spread to the nearby apartment building and caused much more severe damage than what was already done to the car. We had no warning prior to the incident. To our knowledge, the car was in perfect condition. We had bought it brand new 16 months prior and had taken it in for its scheduled maintenance 3 times. We are unaware if the vehicle has been inspected yet or if they've discovered the origin of the problem. All we know is that the insurance company and firefighters confirmed it wasn't arson, as the fire was contained to the engine block and front end of the car, and they also confirmed we were not at fault. Vehicle caught fire while it was parked and turned off.
Electrical system, Jul 14, 2022
Battery is draining for no apparent reason. As stated in several class action law suits, defects in these vehicles ( Subaru Outback 2015-2020) cause the batteries to drain, replacement batteries also drain. The Subaru Outback battery drains because of the Controller area network (CAN). When the vehicle is shut off, the CAN system should enter sleep mode so only a limited amount of electrical current is used. However, Subaru software errors prevent the CAN from entering sleep mode when vehicle is turned off. This software error will drain the original battery and every replacement battery installed in an Outback. Once the battery is drained, I am stranded. Reference law suits Daley v. Subaru and Tomasian v. Subaru. Subaru needs to fix all Subarus that are affected by this battery drainage issue. I have been experiencing this problem since we bought the car. First time, I thought I left something on, subsequent drainage issues I know that nothing has been left on. I now keep a trickle charge unit on the battery while in the garage at all times.

Windshield has needed constant repair due to either small debris or even in one instance, self-cracking. On-board unit is constantly turning off.

On multiple occasions I have had the infotainment system (the touchscreen) either freeze, go completely blank, or reset itself while driving. Most often this has happened while using Apple Car Play but that's not always the case. When this occurs, I also get a message that EyeSight is not available. While this has not caused me to have an accident the potential is there. I have had the screen go blank while using navigation in an unfamiliar area, I've had it go blank while driving down the highway. It's very distracting and you can easily miss your exit or worse. Subaru has no fix for this other than updating the software approximately every 6 months in hopes it will solve things. To me this is totally unacceptable.

The Navigation system will randomly go blank and then restart while driving. This not only affects any navigation which is currently in progress, but also disables the Cruise Control, Eye Sight, Lane Departure and other Safety devices. This has occurred numerous times while driving on an interstate highway and is dangerous and life threatening.

The contact owns a 2021 Subaru Outback. The contact stated while at a traffic light, the vehicle stalled. The instrument panel lights illuminated then went dark. The police came but there was no police report filed. The police had the vehicle towed to a dealer. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 12,500.
Other or unspecified, Fuel/propulsion system, May 27, 2022
Since we bought our 2021 Subaru Outback in May 2021, the vehicle hesitates when accelerating mainly after filling up with gas but also at other times. We have taken the vehicle in 4 times for service, but Subaru cannot duplicate the problem. Another issue we are having is that every time it rains, there is a puddle of water that forms on the passenger side floor board. We have taken the vehicle in 4 times for service, but Subaru cannot duplicate the problem.
Exterior lighting, May 23, 2022
I have issues with the headlights on my Outback. They are very bright to the point that i get flashed on a regular basis by other drivers thinking i have my brights on. Just this morning coming to work I passed someone on the Ohio Turnpike and they must of been blinded by my lights because they then got right up behind me and started following me with their brights on. These lights are a danger to other drivers and It makes me worried for my safety because of the actions of other drivers if they think I'm not turning my brights off. I told the dealer service department where I bought my car and they didn't take me seriously. I found a forum on line where other subaru drivers complain about the headlights and it goes back a couple years.

Crack in windshield, line of sight of driver.

After jump start several check engine lights came on, cruise control did not work. lane control and "EYESIGHT" failure warning light was on. Subaru dealer replaced battery under warranty
Visibility/wiper, May 5, 2022
on January 3, 2022 my windshield cracked and spread right away. I took it to get it fixed. On May 4, 2022 my windshield cracked again and spread immediately. Both times it started from the edge and went inwards. I consider this as a safety hazard for the windshield to crack and spread so easily. This is the second time and we are only covered for 2 replacements on the warranty in a year. This expense can add up quickly

Like many others have complained about, a small rock chip in the front windshield has spidered out across nearly the whole length of the windshield within a few hours of impact.

We bought this vehicle new and since we have had issues with the infotainment shutting down multiple times while driving. The infotainment screen along with all safety features associated with the electronic panel turn off. We have taken it to the dealership multiple times and keep getting told that they can't replicate the problem. We have recorded the issue and sent proof but Subaru manufacturing keeps delaying any inquiries in hopes to bypass lemon law.

The contact owns a 2021 Subaru Outback. The contact stated while driving 20 MPH, the brake pedal was depressed; however, the vehicle independently accelerated. There was no warning light illuminated. The vehicle struck the curb before coming to a stop, causing damage to the rim and tire. The vehicle was towed to the dealer but was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 16,000.

I believe there is a software defect associated with the infotainment system. The system also includes car information such as car data, audio/radio, navigation as well as other items related to modern car's functionality. The issue is when a mobile is plugged into one of the two from USB port, the infotainment will randomly reboot itself. When this happens the screen turns black/bland while rebooting occurs. This can happen even while the vehicle is in motion possibly causing severe distraction resulting a safety issue. (Imaging driving down the highway and your car reboots without warning.) Reboot takes about two minutes during this time the vehicle is drill drivable but is very disconcerting to the driver. This issue is also a major topic with online forums such as www.subaruoutback.org under the Gen 6: 2020-Future section. https://www.subaruoutback.org/threads/2020-outback-software-gigathread.517684/page-340#post-6235066 Attempts to reach the dealership has not proven to be resolvable.

Tiny spec of one sand grain instantly put a 14” crack across a windshield of a 2021 Subaru Outback I have pictures, how does a spec of sand crack a windshield?

I have had this vehicle since @ 6/30/21, under 4,000 miles. Sometimes when I'm driving, the car will suddenly brake or lurch when I am not near another object or person. I drove down the highway once when this happened and it was very concerning. I have also been in the middle of an intersection when this occurred, as I was turning left. It has happened approximately 10 other times since I've had the vehicle. Today it happened and a truck was behind me; thankfully I did not get hit.I brought this into the dealereship twice and they claim there is nothing wrong with the car. There is definitely something wrong with the car; it's dangerous. My car is available for inspection upon request. I and others are at great risk for an accident. I remember flashing lights on a few occasions, not today. When I went online to check for recalls, I noticed many other Subaru owners having the same issues.

Noticed a 6 inch crack on passenger side starting under the wiper. Crack started spreading across the windshield, now about 18 inches long.

The contact owns a 2021 Subaru Outback. The contact stated that while his wife was driving at an undisclosed speed, she noticed a crack on the center passenger’s side of the windshield. The contact took the vehicle to the local dealer, where it was diagnosed with needing the windshield to be replaced. The vehicle was repaired but continued to experience the failure with the new windshields. The contact stated he had the windshield replaced a total of three times. The manufacturer had not been informed of the failure. The failure mileage was approximately 17,000.
Forward collision avoidance, Mar 28, 2022
*Eyesight system detects collision hazard and applies brakes when entering certain curves. *Unexpected braking in curve, particularly when roadway is wet poses a danger to driver and other motorists. *Not reproduced by dealer or service center, problem is captured on dashcam video. *Vehicle has been inspected by dealer *Eyesight system seems to "glitch" frequently, causing a variety of warning lamps on dashboard, full shutdown of infotainment system, and disabling all built in eyesight safety features.

I walked outside my house yesterday morning to find my 2021 Outback XT idling in the driveway. I may have failed to turn the engine off, or it may have started itself. Nonetheless, I calculate that it burned about five gallons of gasoline and probably ran all night. The car should not be able to run for hours on end! This is a clear problem--an overheated catalytic converter could start a fire, someone could have jumped in and driven away, or--much worse--it could have been running in an enclosed area and filled it with CO.. This car does have remote starting capability, so I wonder if that somehow played a role. It also has the start-stop function to save gas. I have noticed that if I stop the car and hit the start/stop button right away, it sometimes seems to stop but then runs on. I strongly believe that the car should not be able to run on like this. Couldn't Subaru build in a a timer to turn the engine off after, say, one hour? These are not police cars and do not need to be able to idle for hours on end. Thanks very much for your kind consideration!

Windshield has cracked for no reason. Heard a small cracking noise driving on the road. No accidents or anything, see a ding on the windshield and a crack growing after two days of parking in the garage.
Visibility/wiper, Feb 28, 2022
The windshield cracked from the bottom corner and slowly spread across the entire windshield. I took a picture before replacing the windshield, a repair that cost ~$900 to replace and recalibrate the eyesight system.

THE MAIN COMPUTER SYSTEM THAT CONTROLS THE EYESIGHT SYSTEM, CRUISE CONTROL, LANE DEPARTURE, ALL HVAC CONTROLS, NAVIGATION, ETC. SHUTS DOWN (GOES BLACK), AND REBOOTS RANDOMLY. WHEN THIS OCCURS, ALL OF THE FUNCTIONS AND CONTROLS ASSOCIATED WITH THE COMPUTER SYSTEM ARE LOST. CRUISE CONTROL DROPS OUT AND THE BUILT IN SAFETY FEATURES ARE DISABLED. IT IS DISTRACTING TO THE DRIVER AND REQUIRES THE DRIVER'S ATTENTION TO RESET FEATURES THAT WERE LOST. IT IS A KNOWN PROBLEM BY SUBARU AND HAS NOT BEEN FIXED ON MY VEHICLE FOR OVER A YEAR NOW. THIS COMPLETE COMPUTER BLACKOUT EVENT OCCURS ALMOST EVERY TIME I DRIVE THE VEHICLE.
