Windshield developed a 10" crack overnight, parked while it was snowing in Boulder, CO. There was no damage prior to this past night. This problem is widely reported on [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle is equipped with EYESIGHT. I was driving to my home after work at night and suddenly the infotainment system screen went blank; including Braking Assist, Adaptive Cruise control, Lane assist, Emergency Braking etc including Navigation, also the HVAC shut off and EYESIGHT that controls these as well, shut off. It was suffocating in the car due to no A/C and thusf I tried to pull over at a remote text-stop place and tried restarting the car but in vain. All screens were dark, no warm air, I couldn’t see what direction I was driving to, as well as I solely relied on navigation. I brought this car for it’s safety features and warmth in this cold temperature in UPSTATE NY and this happened. I waited for 20 mins, charged my phone for only 4-5% with a fellow citizen who was waiting there as well and checked online just to see a lot of people reported the same issue with 2021 Subarus with EYESIGHT. And there is NO way one can fix it. I tried contacting the dealer but in vain. I am afraid that if this would happen again, I wouldn’t be in a situation to face this scary experience.

I have experienced premature rear brake wear and excessive tire wear. Issues with infotainment system and pre-collision braking system. (1) Regarding Tires: Performed all dealer recommended tire rotations and aligned vehicle when recommended. Needed new tires at 31,169 miles. Tires showed excessive inside wear. Bought new tires from a 3rd party shop and had alignment done with hunter alignment system. Showed rear right camber at -2.0. Subaru recommends -1.8 to 0.3. Rear camber is not adjustable on this model. Took vehicle back to dealer for brake job and they said camber was fine...there is a spec for a reason. Did not want to attempt to bring it in spec with aftermarket kits (i.e. adjustable cam bolt) or fix under warranty. (2) Regarding Brakes: Needed new brakes at 31,169 miles. Not covered under warranty and not what I would consider typical wear based on my driving style and my past experience with Subaru vehicles. If this is an expected side affect of the EBD system I would highly recommend Subaru consider ways of improving brake life on their vehicles. (3) I have the Onyx XT trim with navigation. Infotainment system is constantly glitchy. Examples include booting with blank black screen, failing to load, excessive lag while operating system or will freeze and beep repeatedly while buffing a menu selection. Also, had my car battery replaced under warranty within the first two years due to a bad battery. (4) Issues with ADAS system, specifically pre-collision breaking. This system is extremely sensitive and will over-react / take control in certain situations where I didn't need it to even when I was in the process of braking. Have had this system activate on the highway at high speeds while switching lanes on the highway or when having a vehicle merge quickly into my lane in front of me. Constantly, have to turn off this system which is a chore as this system is defaulted to always being on. Do not feel safe driving with this system on.

Received error code P2682, a faulty Thermo Control Valve. This happened on 11/17/2023. Car potentially could have quit running in traffic. Subaru has identified the issue with TSB 09-80-21R. They have changed the design of the valve due to the many failures. My car has 74,000 miles. My brother in law has the same vehicle with 57,000, and his car is in the shop today for the same issue. The service tech working on his vehicle stated that he does a couple of these repairs a week, and that Subaru knows this part will fail and should issue a recall

The contact owns a 2021 Subaru Outback. The contact became aware that the VIN was included in NHTSA Campaign Number: 23V755000 (Power Train) however, the part to do the recall repair was not yet available. An unknown local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

while i am driving my cruise control will just stop working causing the auto braking feature to stop also
Visibility/wiper, Oct 24, 2023
Just purchased this vehicle certified pre-owned 2 months ago. Car was parked and spontaneous windshield crack started on drivers' side and has now advanced up through drivers visual field. A simple google search shows this to be a chronic, documented issue with MANY Subaru vehicles. Driving is limited and this is a costly fix for a fault not on the consumers end. I have contacted warranty and consumer protection before I call to schedule a replacement. ZERO problems or damage to vehicle before this, car wasn't in motion and as evidenced by photos it had no physical compromise causing this.
Visibility/wiper, Oct 4, 2023
I have has to replace the windshield 3 times in less than 3 years in my 2021 Outback. Only once was there a definite impact from a rock. In that case, the glass broke in 5 directions across the entire windshield. The other two times, I simply woke up to a huge crack. It seems that this is an extremely common problem with this model, and my insurance says they will drop me if I continue to make claims at this rate.

Eyesight driver assist went out rendering safety features inoperable. Touch screen also blanked out so unable to adjust a/c, navigation,radio etc. Car had been on long distance all hiway drive and at 7 hours systems failed. Weather was in the 60s, overcast and it was in the afternoon. Pulled into rest stop and turned engine off then restarted but still failed. Drove 2 more hours and next rest stop systems came back after letting car sit off for 10+ minutes.

Window cracked when hitting by a small chip on the high way
Exterior lighting, Sep 20, 2023
I purchased a new 2021 Subaru Outback Onyx Edition XT in May of 2021. The headlights have been a continual problem and I cannot get a solution from the dealer. They are way too bright. It’s a safety hazard to oncoming drivers. I also believe it’s a personal security risk to me from angry drivers. And there's nothing I can do about it because I don't have my high beams activated. The headlights need to have two separate intensity settings, one for low beam and one for high beam, but they do not. Currently, the low beam and high beam use the same intensity LED. The switch between high and low beams does not change the intensity or brightness. It merely activates a motor that moves a metal plate. The plate acts as a shutter that changes the angle the lights shine so the driver has a broader field of vision. The intensity of the lights do not change. The high beams are always on even when not activated. No wonder oncoming drivers are flashing their high beams and getting angry. I have voiced my concerns to the Subaru dealer who checked my headlights and said they were properly aimed. I have voiced my concerns on the Subaru forum and found many other drivers are experiencing the same problem. Some people on that forum suggest re-aiming the headlights so they point lower. This does not solve the problem. Doing so limits visibility to a very short distance ahead of the vehicle creating a different safety issue, not being able to see objects, animals, or people in the roadway. FMVSS No. 108 requires 2 intensity settings for motor vehicle headlights. Subaru has not provided that and is in violation of that federal regulation. I am requesting that NHSTA exercise whatever regulatory authority it has to enforce this requirement including issuing a recall on the Subaru Steering Responsive Headlights. Watch 18:45 to 21:30 of this YouTube video to see the inner workings of these headlights: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 2021 Outback XT which we purchased new on April 15, 2021, would not start on September 15, 2023. My spouse had a medical appointment that morning. On September 18, 2023, the vehicle would not start again. My spouse had a medical appointment that morning as well. This same problem occurred several months earlier. On the morning of May16, 2023 I called the dealership's service department for a service appointment. This was the first such incident and caught me totally by surprise. Here is a direct quote from the Service's Manager's May 19, 2023 email. " The tester/charger determined that your battery was healthy, had a good state of charge and accepted a good rate of charge and also held the charge. The battery has no fault, the drain was the issue determining replacement of your battery was unnecessary and not warrantable." The dealership service department manager went on to state "it (battery)required 3 hours and 45 minutes of charging". Following the May 16, 2023 service appointment the vehicle performed as expected until the morning of September 15, 2023. On September 19, the vehicle was again taken to the dealership for servicing. During this visit, a "new battery" was installed by the service department because they determined the existing battery failed their test. The service rep stated the “new” battery will fix the problem. Also, the service rep stated, when asked, that the Electronic Control Module was updated but the Data Communications Module was not replaced. Additionally, the rep stated, when asked, the “new” battery did not carry the normal warranty because it was installed under the vehicle’s existing 3-year warranty which expires on April 15 2024. This limited battery warranty makes no sense. Since the May 16, 2023 incident, we experienced emotional tension every time we have driven the vehicle, dreading it would not start when we needed the vehicle the most. We are 70+ and believed that we were purchasing a safe vehicle.

I was driving and suddenly 13 flashing lights and codes from check engine to loss of cruise control and RAB -dealer says it needs a new thermo control valve (thermostat). This failed part has been common on Subarus for 3 years-reported on internet and even to the point where a guy sitting next to me today with same car and year and same $1800 bill and diagnosis. Should be a recall. Part was redesigned in 2022 I read.
Electrical system, Service brakes, Fuel/propulsion system, Sep 5, 2023, crash
On Sunday, August 20, 2023 I was pulling into a parking spot in front of an Anytime Fitness at a local strip mall. As I applied the brake, the motor raced and accelerated driving me into a pillar outside of the fitness center. I was in shock, not understanding what had happened. Had I chosen to park one stall to the right, the car would have gone through the window of the business instead of the pillar. Considerable damage was done to the pillar and to my 2021 Subaru Outback, but I was not injured, and no one else was injured. I had the brakes checked at my vehicle service center and was told the brakes were functioning as they should be. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. No warning was provided by the vehicle. The crash occurred in two seconds.
Visibility/wiper, Aug 23, 2023
Went out to car and windshield had a 6 inch horizontal crack in the beginning at the center of the frame the passenger side extending towards the driver side. There was no chip or point of impact noted. Appears faulty placement of windshield like on prior model class action.
Service brakes, Aug 22, 2023
With 22,000 miles my front rotor brakes need replacing and I don’t have a heavy foot! This is my 5th Outback and so my history vouches that I’m not a driver that wears down brakes or tires. When I did some online searching, there are a number of people posting with the same experience. Subaru knows there is a problem because they are quick to replace under warranty. But this is dangerous. In my case, the brakes were checked just a few thousand miles ago and the were “ very good”, scored 8. Fortunately a friend was sharing the driving on a long trip and they caught that there was a problem. I made a service appointment while we were on the road. Please investigate and have them come up with a better solution than resurfacing the breaks after just 22000 miles

When driving on Interstate Highway 44 at approximately 45mph the windshield suddenly cracked on the lower passenger side of the vehicle. There was minimal traffic at the time of the incident and the roadway ahead was clear.
Other or unspecified, Forward collision avoidance, Aug 15, 2023
The windshield has spontaneously cracked on 4 separate occasions. Subaru denies this is a defect and claims all have been caused by rock chips. This is not true. The cracked windshield has caused the vehicle on numerous occasions to slam on its breaks while traveling at 55 mph or greater as it “senses” a collision. This has nearly caused 3 accidents so far.
Visibility/wiper, Aug 8, 2023
Windshield spontaneously cracked. There is no obvious sign of impact from an external object, verified by location replacing the glass. This is the second windshield that has spontaneously cracked in less than a year's time.

The contact owns a 2021 Subaru Outback. The contact was unable to start the vehicle. The contact stated no warning light was illuminated. The contact jump started the vehicle; however, approximately 5-7 days later, the failure recurred. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had been informed of the failure. The failure mileage was approximately 48,000.
Visibility/wiper, Jul 5, 2023
Have owned the vehicle less than a year and it has already acquired 2 chips. One of the chips spread out to a larger crack immediately.
Other or unspecified, Jun 28, 2023
I just had my second windshield failure in 2 years on this vehicle. The first time a rock hit me, but today a ~ 12" crack appeared out of nowhere while I was driving down the highway with no impact. The windshields on this vehicle seem overly prone to cracking, whether or not any impact is applied. I'm worried this will interfere with the eyesight functionality.
Air bags, Forward collision avoidance, Jun 23, 2023
Yet to be diagnosed but possibly the cockpit control computer. Dealer service department has not been able to diagnose. No components have been replaced yet except for a software update that did not correct the issue. Safety systems all report as not functioning, These include all "eyesight systems";the air bags, automatic emergency braking, lane departure and lane keeping. Additionally all center console functions are not functional, including HVAC and radio. The vehicle has been to the dealer twice where the problem could not be reproduced. No other inspection has been performed. No warnings or other messages appear prior to the failure. The failure persists for approximately 10 minutes, after which normal operation resumes. I write this following the fourth occurrence of the failure.
Fuel/propulsion system, Jun 14, 2023
My wife turned into a parking spot slowly with her foot on the brake, and the car suddenly accelerated without warning. It went up on the curb while my wife slammed on the brake and stopped the car. She then put the car in reverse and backed into the parking spot. Came home without further incident but was very upset. I intend to question the dealer, Parkway Subaru in Wilmington, NC. I see articles online that relate problems like this to a number of different models and makes. My wife does not want the car anymore, but how can I be sure any car I replace it with does not have the same problem? 6/15/23 The contact called to add additional information to the complaint. The contact owns a 2021 Subaru Outback. The contact stated that while his wife was driving into a parking space at 1 MPH with her foot off the accelerator and depressing the brake pedal, the vehicle inadvertently accelerated. The contact stated that his wife was able to depress the brake pedal to the floorboard and bring the vehicle to a complete stop.

My windshield has cracked 3 times since vehicle was purchased, the last time within 2 months of replacement. The first 2 times the windshield was replaced by the dealership with OEM glass. There was no visible crack from rocks, etc in the last two incidences...went out in the morning to find that the windshield was cracked across half the windshield after it had been parked and no visible damage had occured beforehand in both cases. ( I have taken pictures of this last incident... insurance notified, but no inspections took place. no warning lights, etc appeared pryor to cracks)
