Gas cap was not secured overnight. The next day every ADAS function both safety and convenience was disabled and their lights were on. Users guide said car should recover after a few miles of driving. 100 miles and multiple restarts later it did not. It was taken to the dealer where they cleared the error for free. Poor design that a loose gas cap could cause a collision due to lack of ADAS. Dealer said it is a known condition with all Subaru models.

I was driving to a medical appointment in Ann Arbor Mi, and was in the area where [XXX] has a few big turns in the road .... like at ... [XXX] .All of he sudden the car started to accelerate a little on the turn so I attempted to brake the vehicle and I could not feel the brake pedal. I slowly moved into the right lane and frantically trying to slow the car down. I still could not feel the brake pedal and I believe when I hit the speed control off is when it slowed down and I was able to finally brake the car. It all happened in a matter of 10-20 seconds I would guess and it was absolutely terrifying. I have on occasion used the speed control to slow down the vehicle and wonder if that might have some connection.

The contact owns a 2020 Subaru Outback. The contact received notification of NHTSA Campaign Number: 24V227000 (AIR BAGS); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that on a separate occasion, while reversing, the rearview camera displayed a distorted image, compromising the back-over prevention system. No warning lights were illuminated. The vehicle was taken to the dealer; however, no cause for the failure was found. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The contact related the failure to NHTSA: 20V766000 (BACK OVER PREVENTION) however, the VIN was not included. The failure mileage was 61,000. Parts distribution disconnect.

The Subaru front camera incorrectly detected a hazard. The automatic braking system engaged and locked the steering. I skidded off the pavement, causing damage to the car. At the time of the accident, the blind sight warning lights flashed on the dash signaling that they were disabled. I was going very slow in a driveway. No personal damage just property damage and damage to the car. I have let the insurance company know about the issue and the collision center. I have had periodic instances where the warning signals of blind sight disabled have come on the vehicle. I informed Subaru in August 2024 about the issue at my last maintenance appointment. There is also a software update required on the vehicle. I asked Subaru to update the software in August 2024, but I was told by a service technician that it was not possible to update . I had to make a separate appointment for the software update as it took a long time.

On [XXX], I was driving east on [XXX] on the North side of Toledo Ohio close to the intersection with [XXX] . The "Check Engine" warning came on, all the vehicle "Eyesight" functions were automatically turned off, and Pre collision braking and Pre collision throttle control features were activated. There was no danger of a collision at this time, but all of this left me stranded in the middle of this busy four lane highway. I was able to literally crawl to the shoulder of the road. I was not hit, but it was just good fortune that prevented that. This is where my safety was at greatest risk. After about 10 minutes during which I started and stopped the car numerous times, the pre collision braking and throttle were deactivated and I was able to drive the car. I located the nearest Subaru dealer (Yark Subaru Toledo, Ohio) and drove there. The cause of the Check Engine light was diagnosed as a failure of the Thermal Control Valve. I had received a letter from Subaru dated May 1, 2024 stating that this part might fail and extending the warranty for this part. That letter specifically stated that nothing needed to be done until the part failed. There was no mention of the fact that the car would be disabled when it happened. Part was eventually replace on July 1, 2024 two days later. Since then I have spoken to 3 people at Subaru of America seeking to understand why a Check Engine situation caused the vehicle to be disabled. I also asked the Service Advisor at Yark Subaru to explain. They have all been friendly and attentive, but they cannot or will not give an explanation. My main concern is that a Check Engine situation may cause this Pre Collision shut down to happen again. Based on the danger I was in when this happed, I think that there should have been a recall and the Thermal Control Valve replaced before failure. To be clear, the repairs were completed under warranty and Subaru has sent me a $350.00 coupon for future service. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (F

A small horizontal crack recently appeared on my Outback's front windshield while it was sitting in a garage overnight. The crack started from the passenger side and has now crept over to the middle of the windshield. Previous to this incident, the car had been sitting unused for over a month, so there was no opportunity for rocks or other debris from the road to cause the crack. This is the second time that the windshield has developed a crack out of thin air. I have replaced the windshield at least five times since owning the vehicle, in addition to having small chips from rocks repaired twice. These incidents are potentially dangerous and could possible interfere with the vehicle's automated systems such as collision detection and cameras.

Thermo Control Valve assembly has failed resulting in loss of use for the following: Rear Automatic Brake, Eye Sight lane keeping, loss of heat in cabin and failure of coolant to circulate within engine possibly leading to engine failure, loss of cruise control and check engine light coming on. Reference TSB [XXX] . Without cabin heat vehicle is not useable in current cold temperatures (Currently 22 degrees Fahrenheit in Ohio on December 14, 2023). Dealer has confirmed part failure. Issue must be addressed to continue operating vehicle so I paid $1185.87 out of pocket to repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A well-known failure of the Thermal Control Valve (TCV) occurred, which disabled many or most of the safety features on the car in addition to crippling the heat output in the cabin. Additionally, depending on which way the valve sticks, it could overheat the car and ruin the engine, or worse. Car is under 4 years old and repair estimate is nearly $1900. There is a technical safety bulletin [XXX] that outlines a redesigned TCV. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On November 21th, 2023, we were driving on a 30 mph street at 8:00 pm with no traffic and our automatic emergency braking system deployed on our 2020 Outback, we jolted to a stop for no apparent reason. This could have been dangerous if a car was behind us. Just had our oil changed with free inspection at Miller Hill Subaru 1 week prior. First incident. Will have the dealership inspect ASAP. The "Auto Start /Stop No Activity Detected" indicator message light came on afterward.

Per Subaru there is something wrong with the Cockpit Control Module (CCM) that is causing a constant / parasitic draw on the battery. This results in the battery being dead within 4 hours, leaving us constantly stranded. Because the CCM also controls the electrical system, many of the safety features (auto breaking, lane departure, etc) turn off randomly. This is the diagnosis from our local Subaru dealership: COCKPIT CONTROL MODULE IS DRAWING 2 AMPS. WITH COCKPIT UNPLUGGED THERE IS STILL A 1 AMP DRAW. WILL NEED TO REPLACED CCU THEN FIGURE OUT WHERE THE OTHER 1 AMP DRAW IS. UNABLE TO DIAGNOSE WITH MULTIPLE SYSTEMS DRAWING I have opened a case with Subaru of America, but with no resolution.

While we were at a speed of about 55 mph on a state highway, I had just selected cruise control when all the lights went on in the dash--including the warning lights for the brake, the check engine light--and power shut down in the vehicle as if we'd run out of gas. We were able to keep a very slow speed of about 20-25mph, but had to activate the 4-way flashers to alert other drivers that we were losing speed. We managed to get over to the shoulder and call for a tow. We feel this was a catastrophic failure of the vehicle, which endangered both of us. At least we still had power steering. At the dealer, the techs advised us that the issue was likely due to a failure of the electronic thermostat control. The car was in the shop for a week, and was repaired at no cost to us. The thermo control valve and all related parts were replaced. If not under warranty, this would have cost over $2K. We had no warning that this component was failing.

I purchased the lease for the vehicle in January 2020. I first notified Subaru in Austin of an obvious "glitch" with the computer operating system in April 2020. The "glitchy" OS challenges came and went, I would notify Subaru and they would remedy the issue with a "patch" update at the service center. On April 29 2022 a clear night and a suitably clean vehicle, the RAB system completely failed to recognize/notify/respond to a mailbox behind me, upon impact the mailbox broke the rear windshield. on June 28 2022 the vehicle fails to start, and is "surging" completely draining a new jumper box, and then promptly burning it out, the box will no longer operate. Put in a new battery(#1), make an appointment for service on the vehicle. The dealership replaces the battery(#2), computer updates are completed. Vehicle goes to the body shop for the rest of the work to be completed. 28 days later, I arrive to pick up my vehicle, all work is complete. However the vehicle will not start (again) Auto body shop replaces the battery(#3).on 9/23/2022 after dark, my Subaru Outback 2020 Limited, stops and puts its Parking break on., all dials spike, then dies, rear hatch signal goes off continuously, regardless of its actual state of open/close. The vehicle refuses to jump with a new jumper box. Outback 2020 is successfully jumped by a newer vehic. New battery installed(#4). 9/29/2022 another appointment at Subaru service center to look at my vehicle, they swap out the battery(#5) and update computer. Upon pickup vehicle is without trailer lights, 3 airbag lights on, ABS light on/off. 10/17/2022 appointment at a different service center for an Oil change service, 10/18/2022 diagnostic check appt, 3 blown fuses found. 11/16/2022 Austin service, found many lost comm. codes.- reprograms , engine control module. Outback 2020 intermittently has problems opening and closing hatch/windows, display loading issues, many warning/hazzard lights & signals on/off (from April 2022- present day.)

While driving my Subaru Outback, I encounter a problem where the Starlink Multimedia system abruptly goes black. Shortly after, the driver information center also goes black. Although the car continues to run, the cruise control, if engaged, and the EyeSight safety system shuts off as well. Both systems then undergo a reboot.

While driving on the NYS Thruway (I90), I started to pass a Tractor Trailer, I put my blinker on and began moving to the right to pass. There were 2/3 cars in back of me also passing. I was using cruise control and I began to put my foot on the accelerator to finish my passing and move over to the right hand lane to let the other vehicles pass me. However, upon accelerating, my car started to drop power, multiple lights displaying simultaneously indicating a potential problem. (Eyesight Assist, Vehicle Dynamic Control, Brake & Engine Lights), the vehicle started jerking back and forth and I lost all but maybe 5 miles of power. My choice at that time was put my blinker on and try and move to the right - letting the Tractor Trailer pass me on the right and HOPE there was not another vehicle behind so I could move over safely at that crawling speed or go to the left into the gully. This could have been a multiple car collision and maybe fatalities due to the speed and loss of control of my vehicle. After towing to the nearest dealer, they determined it was the Thermo Control Valve. I see now that there is a "service bulletin" and design change of this component and that other Subaru drivers have been affected the same way. This is a very serious situation. I ask, why no recall from Subaru. I have been without my vehicle now for 4 days and may not have it back until next week. I am very fearful of driving that vehicle again.

-The windshield has cracked in the same place for no apparent reason. -The cracked windshield can affect the use of the safety systems built into the windshield. -I'm not sure how this can be "reproduced" as we are talking about a broken windshield although the windshield has been fixed already once and now, the second break has occurred. -Not inspected but replaced once. It is currently broken and can be inspected again if need be. -The first one appeared in August 2022, the second in May 2023

A crack has spontaneously appeared at the base of my windshield after no apparent damage. The crack is spreading across my windshield and will affect my adaptive cruse control and automatic emergency breaking if it interferes with the Subaru eye-sight system at the top of my windshield. I have not taken the vehicle in for service but I did see this was an issue that lead to recalls on previous outback models but not currently a recall for the 2020 Subaru Outback. I do not have any current warning lamps or messages.

Mar 15, 2023

When we started vehicle, a wide array of systems shut down including cruise, Eye Sight, lane detection, auto high bean, adaptive light cornering - essentially anything “automated” or assisted - along with the heating. The car ran at a higher RPM at idle - 2000 vs a usual 700-800 - and rough shifted at speed. Again, as if the automatic transmission lost its sync. The water temp gauge was also off. Have since learned this was the “thermo control valve” and somewhat of a known fault on Outbacks of this year. We were lucky to reach home from the long trip we were on and to the dealership. At the dealership, the service team did not admit this was wide spread. Nor did they tell us there is an updated part from Subaru available. They intend to install the OEM part, which concerns us that in another 40-50k we will face the same $2k problem. We are unlucky that we just went over 60k miles, so this will not be covered under Subaru’s 60k drivetrain warranty. That Subaru is covering a cooling system problem under the guise of being drive train tells me they know they have something to keep quiet.

I pulled into my driveway, came to a stop and planned to back up a short distance to be nearer the front walkway. Before I could shift into reverse the car started to accelerate forward. I slammed my foot onto the brakes which had no effect on the acceleration. The car stopped when the lower bumper hit and ran up onto a large boulder on the edge of the driveway. The car was partially wedged on the top of the boulder but I was able to back it off the boulder, park and turn off the car. I have scheduled an appointment with the service department on February 1st, at the dealership where I purchased the vehicle in June 2020. Of note, I had a routine oil change and service check at this dealership on January 16 with no engine problems noted.

•Driver’s window failing to properly and completing retract. This has been particularly troublesome in the bitter cold of Northern Minnesota. On each visit to Subaru I have requested that the window be repaired. All efforts have been unsuccessful. •Battery failure without cause or prior warning signs. On previous visits the Service Center failed to address and resolve the battery problem that I brought. In my most recent visit they referred me to a Legal Settlement action which prevents them from further addressing the battery issue. I brought the vehicle in twice for repair/replacement of the battery. Not resolved. •Eyesight Driver Assist malfunction. Upon presenting the issue, the Service Manager suggested that the cause was sunlight hitting the sensors and he did not work on the issue. Even when I noted that the problem happened in the evening as well as during the daytime, no response. •Check Engine Warning Indicator signifying any number of important malfunctions while also causing Cruise Control, Eyesight, RAB, and other critical, electronic systems to deactivate. More importantly, the Subaru Service Center informed me that there is a life-threatening risk associated with the underlying cause of this Check Engine light appearing, and, consequently, they would not permit me to drive the car from the Service Center until necessary repairs and part replacements were made. I have been waiting over two months for the automobile to be repaired and returned to me. I had previously brought the vehicle in specifically for this issue. At that time the Service Center failed to correct the problem and suggested it would disappear on its own (the warning light would turn off after a number of ignition starts). When I requested that they clearly understand the problem and fix the lighlight warning, the manager refused to continue to work on the vehicle.
