- Driver and Passenger window stuck down (won't close) in extreme cold temperatures - I feel my safety is at risk because I had to drive my car miles in frigid temperatures with my window stuck open. - My dealership acknowledged the problem, but were not able to reproduce it as it was 59 degrees when I took it in. - My vehicle was not inspected by anyone other than the dealer - I had no warning of the problem I have a 2020 Subaru Outback Limited. Since I bought the car, there have been multiple incidents where the driver or passenger window got stuck open after being rolled down on very cold days. Several years ago ,shortly after I bought it, my Subaru dealer explained to me this was happening because Subaru changed the rubber content in the window gaskets to a harder rubber. Then, when there is dirt on the insides of the gasket, the gasket drags on the window and the actuator opens the window because it thinks it detected it was closing on something it was not supposed to close on. The fix to be able to close my window was to take a screwdriver and a T-shirt or thin towel to clean the insides of the gasket that touches the window. Subaru knows about this problem. As this is a safety hazard and dangerous in cold weather, I do not understand why there has not been a recall. I took my car to the dealer today. I was told that it should not happen again if I keep the gaskets clean. As a Subaru is supposed to be made for offroading and extreme weather conditions, I would think that something as basic as being able to open and CLOSE a window is not too much to ask. Do you really expect me to clean the inside of window gaskets to keep my windows from sticking? That is just trying to normalize a problem that should not be not be normalized. My passenger window got stuck a couple of weeks ago and I had to drive home 7 miles with it open when it was 0 degrees out. I tried to clean the gaskets using a screwdriver and a rag, but it would not work. Please recall!!!

I am reporting defective windshield. I’ve had windshield replaced 3 times when just the tiniest pebble tinged. My daughter also has a Subaru Outback and 3 windshields replaced. There must be a defect. Now that we have replaced the windshield several times, State Farm insurance has dropped us because of the number of claims. Most definitely a danger when a tiny people shatters the glass and pieces of the glass hit your face and eyes. If there is another agency I should report this, kindly let me know.

- Infotainment center freezes making controls inaccessible. I live in the desert where temps reach 120+ in the car and not being able to turn on the AC is dangerous. - Windows will not roll up once they are rolled down, especially after it has rained or after washing the car. - Driver side Door Sensor Switch broke. This would keep the interior lights and infotainment center from turning off.

I noticed when the weather is wet, closing the front windows is slow. This kept advancing and now it won't close at all. Today, 12/28/2023 it wouldn't even come up more than half an inch then goes back down. Done some online research, and lots of people are reporting this with several Subaru models and dealers only say it needs lubrication.

The windshield is ridiculously susceptible to cracks. I’m on my third windshield in 4 years. I had the windshield last replaced in October and had a new crack within a month. I didn’t even notice anything hitting the windshield with this last crack.
Visibility, Dec 20, 2023
The contact owns a 2020 Subaru Outback Premium. The contact stated that while the vehicle was parked in the garage, the contact noticed the front windshield was fractured. The contact stated that the crack was in the middle of the windshield which was the same area that the previous windshield fracture had occurred. The contact stated that the front windshield had been replaced two times previously due to the same failure and this incident is the third occurrence. The vehicle was taken to the dealer and the contact was informed that the failure was due to the windshield glass being too thin. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 39,000
Engine, Fuel/propulsion system, Dec 15, 2023, crash
On 12/6/2023, as I slowly turned right into a parking space, my car suddenly surged forward and accelerated without my input to the gas pedal. The brakes did not work, and there was no resistance from the brake pedal when I repeated to push it. The car continued to accelerate for about 80 ft as I focused on steering to avoid hitting other cars parked in the lot. The car ran over a curb, up a grassy area, and crashed into a row of trees. The airbag did not deploy. I sustained neck muscle strain/whiplash, and bruises to my chest and right knee. My safety was at risk, as well as anyone or anything that was in the car's path since I had no control over the acceleration or the brakes. The car is a 2020 Subaru Outback with about 44000 miles. It is in a body shop and they have not yet determined if it is safe to work on. So far, they have observed the engine race when the car was turned on. There were no warning signs prior to the acceleration. When I called the Subaru dealer service department, I was told that they never heard of this before and it had to have been my fault. They said I could bring it in after the body damage is repaired, and that I can pay for a diagnotic report. However, they expect that the report will not show anything.

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)
Steering, Nov 29, 2023
Car lurches when put into gear, Transmission make loud chirping noise when place into gear from park, vehicle shudders when turning. Car has had all recalls updated. Symptoms have been reported to two different dealers. Dealer in Traverse City MI indicates this is "normal". Issue has continued since first noticed.

Service brakes, Forward collision avoidance, Nov 22, 2023
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.
Electrical system, Exterior lighting, Nov 21, 2023
Automatic Braking system has almost caused a rear-end collision 5 times, because it thinks a shadow is an object. We’ve brought the car to the dealership but they told us twice that they can’t replicate the problem. That doesn’t change the issue. I don’t want to wait until we have a collision and have to go through physical therapy and repairs to address this. Front headlights are blinding other drivers causing them to flash their brights at us regularly on the freeway and local roads which then blinds us and causing us to slow down and break. The dealership say that the lights can be adjusted but this is a serious risk to us and something that happens every night. It’s stressful to drive the car anticipating this all the time. We’ve replace the starter last year and having issues again. The car struggles to start. Last year they said this was a known issue and also replaced the battery. But it’s happening again. This indicates a more complicated issue in the electrical. I don’t want to have to replace the starter every year.

Thermo control valve broken. Leaves no heat to cabin.
Electrical system, Forward collision avoidance, Nov 15, 2023
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.

Rock hit windshield and cracked Need to be replaced
Engine, Oct 11, 2023
The factory 2020 Subaru Outback Wagon is built with a Thermo Control Valve that is, essentially, made out of a composite plastic. As this part is part of the engine cooling system, it is placed under both heat and pressure. While it controls the anti-freeze to the heater core in the passenger compartment, it is also attached under cover to metal fittings. While the car now has about 90,000 miles, this control valve cracked and began to leak anti-freeze on top of the engine. Without cooling, the engine would likely be ruined. Thus, the car required immediate service. When a fault like this occurs, by the way, the Subaru Eyesight System shuts down taking with it various safety features. I had the defective part replaced and it's replacement is not made of composite plastic but, rather and more appropriately, metal. It is my belief that the selection of the orignal part was a design defect ignoring the potential for differential expansion of the parts when exposed to such temperatures. Failure was inevitable. It is worth noting this is not an inexpensive repair as numerous parts have to be removed to access this valve. Likewise, the service representative made note that numerous other customers have had to have the same service.

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.
