Visibility/wiper, Jun 29, 2023
Windshield randomly cracked while parked. There was no hit to the windshield that was detected. Crack runs down middle of windshield.
Visibility/wiper, Jun 24, 2023
(06/22) - Small pebble hits windshield and creates a "star-pattern" crack measuring 2.25 inches in diameter. Booked earliest appointment for windshield replacement on Tuesday 06/27. Have not touched windshield and have not driven vehicle as of this day. (06/24) - Waiting for windshield replacement appointment; star-pattern crack has extended aggressively overnight while parked under shaded carport (average temp 64 degrees), far beyond what is typical. As of 06/24 there are 2 long cracks extending in opposite directions measuring 9 inches above and 13 inches below original impact diameter. Please note that Subaru has had prior class action lawsuits filed for similar issues regarding brittle/unsafe windshields for Subaru Outback and Forester 2016-2020 models.

While driving on an Interstate highway the engine suddenly lost power and various warning lights lit up on the dash, including brake, eyesight, RAB. Managed to limp to the shoulder without getting hit and had the car towed to the dealer, who replaced the thermo control valve assembly under warranty.

My wife was out this morning meeting friends for coffee. She gave a friend a ride home and she noticed a crack in the windshield on the drivers side. There was no indication that it was hit with a rock or anything else. I see that there was a lawsuit against Subaru for defective windshields.

The thermo-valve controller gives out on this vehicle. Through searches and discussions with two separate dealerships, this seems to be an incredibly common issue. It's enough that Subaru has actually completely replaced the design of this piece for whenever it gets replaced. This triggers a check engine light which already removes many features on the Subaru. My understanding is that this part controls and measures the engine temperature which means that drivers have no clue if their engine is overheating or not when it goes out. Subaru has gotten away with covering this part over their Powertrain warranty since the vast majority of their vehicles are having this part break within 3 years. Most drivers are happy with this because the major ($1500-2000) repair is covered. The issue is that people that drive more often, like myself, are stuck footing the bill for a part that Subaru has admitted doesn't work properly just because we've now fallen out of this 60k mileage warranty. From my research, it's not a part that is greatly affected by mileage, so much as time since the dealerships have noted that every replacement they've seen has fallen within 3 years, regardless of the mileage. For that, I'm asking that there be a true recall put in place for this part. This is a major expense for almost anyone and isn't fair for Subaru to hide behind a warranty that won't apply to everyone when they know they created this improperly. Even the reps at the dealership mentioned that they see this far too often for it not to be a recall, but that most people are still under 60k miles, so there aren't normally issues.

Thermo control valve needed replaced. Check engine light and all safety lights turned on. All safety features were disabled when light came on. Subaru has has a recall on 2019 but not 2020 .
Visibility/wiper, Jun 3, 2023
While driving, I heard a loud POP. I thought something hit the car, but I was not close behind another vehicle or road hazard. For about 15 minutes I thought no harm, no foul. Then suddenly, I saw a long, mostly horizontal crack from the bottom left and extending about 18" toward the center of the windshield. I called the Subaru dealer [where I bought the car] and was quoted $910 parts and $590 labor, but they were unable to give me a service appointment date at that time. I don't feel the car is safe to drive, so I am looking for a quicker repair from an independent windshield replacement shop. At the same time, I researched Subaru windshield cracks and found numerous reports of easily cracking Subaru windshields. It appears that if I replace one Subaru windshield with another Subaru windshield, I may just be waiting for another Subaru windshield crack in the future.

Windshield cracked in the bottom black area. This is a known problem for other model years. Subaru should issue a recall / fix for the 2020 Forester also.

The thermo control valve on my 2020 Subaru Forester is broken and needs to be replaced. I have owned the car for 2 years, am the first owner, and it has less than 19,000 miles. 90 minutes into a drive the "coolant temp low" indicator light came on. After I pulled over, turned off the engine, and turned it back on the check engine light and sport mode indicator light came on, and all ADAS were disabled. The coolant level was low so I refilled it and took it to the manufacturer the next morning. They inspected my car and confirmed it the thermo control valve was broken. It is still broken as I cannot afford the repair and it is available for inspection upon request. My safety was put at risk by not having access to the ADAS forward collision warning, emergency breaking, and lane departure.
Electrical system, May 31, 2023
This vehicle has approx. 45,000 miles and the electrical has failed. We have replaced the battery and tested all components in which they then operate fine. However overnight the battery fully drains, leaving us with no vehicle again. This vehicle has no accidents, maintained every 3 months and the health report even shows no issues/errors. No other symptoms have been noted. this car works and runs 100% like it did day 1 up until 3 days ago. Where it has died overnight every day. Luckily my husband is a mechanic as he indicated the last instance of a new battery going in, the dashboard was flashing and going haywire to the point that it wouldnt stop until he removed the battery. He indicated that its likely this would have been an electrical fire if the battery was not removed therefore could have caught on fire with myself and our 14 month old inside. There were no warnings, no alerts, no vehcile safety alerts, the mysubaru app in fact still says we have a 100% healthy vehicle.

Driving down the highway and the windshield cracks and the cracks keeps getting longer.
Visibility/wiper, May 22, 2023
The vehicle was parked in our driveway in Lafayette, CA on 5/16/2023. Outside temperature reached approximately 75 degrees. The windshield developed a spontaneous crack, horizontally spanning the driver's side edge to nearly the middle. No impact point can be observed along the crack line. The vehicle is available for inspection but has not yet been inspected by any authority. Vision may be blurred or compromised along the crack line, which should be deemed a safety issue. Numerous reports of windshield faults for 2019+ Subaru Foresters have been reported online, though Subaru continues to deny these claims.

When I applied the brake ,the vehicle suddenly accelerated and smashed into my garage
Visibility/wiper, May 18, 2023
My windshield has cracked - huge lines running across the windshield including the driver's side - three times in 2.5 years necessitating I pay out of pocket to replace the windshield each time. I will now need to get my fourth windshield in less than 3 years of having a brand new car. Though I have been told that it was "outside influence" such as a rock, I did not see or hear a rock hit the windshield. Not to mention I have owned many other cars and have never had to replace the windshield so many times. The latest windshield I replaced was less than a month ago and now I have to replace it again. There was a recall/class action lawsuit on previous years of the Subaru Forester and it is not clear or apparent that they have changed the windshield substantially enough that this issue has been resolved. It is dangerous and defective to have a windshield that has long cracks in it so frequently and consistently. My and my family's safety is at risk when it is difficult to see because of the huge cracks in the windshield, particularly at night or in inclement weather (i.e., rain storms). The problem has happened now 3 times in less than 3 years. A product that warrants so much replacement is defective in nature. I have called both the dealership and Subaru USA - who said that they did know that I was not the only one having these issues. The vehicle has been expected by experts at Safelite and I am taking it to the dealership for an inspection with this latest crack. But because they claim a rock hit it then I have to pay for the replacement - but when this happens with such frequency then how can the windshield not be defective? When this is not the standard for all other cars! And it is dangerous to have an unreliable windshield! No there were no warning messages.

The windshield cracked for no apparent reason. It’s a 2 foot long crack, low on driver side. The crack appeared while the car sat parked in a garage. It wasn’t there when the car was parked and was visible when we returned to drive the car. The windshield is so widely cracked, the risk is s sheet of glass will hurt the driver or passenger. We have not taken it to the dealer for repair yet The windshield cracked without warning or sufficient cause.

We hit a deer, front-end impact, then our Forester started on fire and completely burned up. The airbags did not deploy, we were not injured but the car is a complete loss.
Other or unspecified, May 11, 2023
Firestone Wauwatosa, WI told me I need to have them recalibrate the Driver Assist System as part of an alignment I took the car in for on 5523. This added $125.00 on top of a $209.99 cost for the lifetime alignment cost. Laura, in the service department at Zeigler Subaru, Kenosha, where we bought the car, said this would only have to be done if the car had been in an accident. Not knowing what is actually required leaves me feeling unsafe.

Windshield cracked and split to the middle unexpectedly
Visibility/wiper, May 3, 2023
Noticed a crack in the windshield glass today in the parking lot at work. This crack starts at the bottom of the windshield and goes upward about 8 inches. There are no signs of the windshield being hit. I looked this issue up and there is a class action lawsuit going on about defective windshields on certain Subaru models. Mine is included.

While driving the vehicle suddenly stalled and stopped running. The dashboard illuminated with most lights and the check engine message came on the screen. I was thankfully able to get into the shoulder on the road safely without creating an accident or getting injured. The vehicle would not start again and had to be towed to the dealership. I am now out $1800 because I am slightly over my powertrain warranty in mileage on the vehicle. This is a known issue in bulletin: https://static.nhtsa.gov/odi/tsbs/2022/MC-10208664-0001.pdf I am not only disappointed with Subaru of America and NHTSA that this is not already a recall but I am also willing to seek legal action and compensation if this repair is not going to be covered. There are many incidents and reports online of similar issues: https://www.subaruforester.org/threads/2019-thermo-control-valve-assembly-and-warranty-merged-thread.823510/ https://www.carcomplaints.com/Subaru/Forester/2020/drivetrain/power_train.shtml I have filed a case with Subaru of America corporate and am waiting to hear back. Someone is going to cause an accident or end up dead because of this faulty part. It is borderline criminal that this is not already a recall.

The check engine light illuminated and the thermo control valve failed at 3 years old. The defrost and heater stopped working immediately making visibility extremely difficult . The eyesight and automatic braking system were also disabled due to the TCV issue. My Forester mpg dropped to under 20 mpg. The Subaru dealer inspected and confirmed code P26A3 and stated the thermo control valve needs to be replaced.
