Subaru of America, Inc. is recalling certain model year 2021 Crosstrek, 2022 Forester, 2021-2023 Legacy, and Outback vehicles. An insufficient weld may allow water to enter the inhibitor switch, causing it to fail.
An inoperative inhibitor switch may prevent the reverse lights from illuminating and the rearview camera image from displaying, increasing the risk of a crash.
Dealers will replace the inhibitor switch, free of charge. Owner notification letters were mailed January 8, 2024. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WRQ-23.

When I make a forward sharp right or left turn, the tires "shudder". It feels like they are skipping or I'm hitting little bumps in the road. Crown Subaru in Chattanooga, TN, told me the center differential was bad, so I would need to replace the transmission for $11,000. I took it to a mechanic for a second opinion who specializes in Subaru repair. They scoped it, fully checked the transmission, bearings...anything they thought it could be and could not find anything wrong with the transmission or bearings. Nothing that could be causing the shuddering. After visiting a few discussion sites, many Subaru owners have this problem and they are told many different things from their dealerships; all ranging from "it's normal on these models" to an exorbitant repair like a new transmission. Note: when Subaru told me I needed to change out the transmission, they did not say for sure that would fix the issue.

Windshield developed large crack starting on lower passenger side and moving along to lower center of windshield. No incident of a rock or other object hitting windshield. A cracked windshield is a safety concern. Car is going in to dealership to have glass replaced this week. Crack appeared June 2023.

When slowing down the vehicle almost down shifts causing it to lurch forward. Notified Subaru and took to 2 dealers which were all no help. Subaru of America did NOTHING to assist

The windshield was hit by a rock and within 12 hours, a 6" crack developed near the lower part of the windshield. Over the course of the next two weeks, the crack has continued across the entire lower area of the windshield. The windshield is due to be repaired within the next couple of days.

Check engine light. Code showing P2682 and P26a3. There is an issue with the Thermo Control Valve for the MY21 Crosstrek. This is also affecting the Forester and Outback. See this thread: https://www.subaruforester.org/threads/2019-thermo-control-valve-assembly-and-warranty-merged-thread.823510/ Subaru should replace and install the new part regardless if the vehicle is no longer under warranty if a customer TCV has issues. There are customers who have had to pay anywhere between $1500-$2000+ to have this fixed/replace by the Subaru dealer.

The sunroof exploded while driving causing glass to fall into the cabin onto the driver and passenger seats (while driving at highway speeds) and glass shards flew off the back of the car. The car has not been repaired as of yet. The Subaru dealership told me this has happened 4 times this year in my small town alone. I am currently working with insurance to get the glass replaced. The Subaru dealership put plastic over part of the sunroof to keep it from leaking water when it snows and rains. There were no warning lights, symptoms or messages prior to the incident.

Stone chip 2 within a week! 1st repaired next day.
Visibility/wiper, Apr 17, 2023
The windshield cracked while the car was parked overnight in my attached, residential garage. The crack formed in front of the passenger seat, starting at the bottom edge of the windshield and running up about 6 inches. There were no chips or recent (as in several weeks) impacts to the windshield.

Engine shut off at a stop sign and the dashboard lit up like a Christmas tree with alarms sounding. Couldn’t get car restarted. Towed to Subaru dealer and they said there was a connector cable to the starter that was defective. Replaced at no cost.
Engine, Mar 22, 2023
The engine part that seems to be the issue is the starter. The car has an auto cut off when stopped at lights and other times you stop the car. The car's engine is supposed to restart as soon as you take your foot off the brake. As the car's engine heats up, the car's engine does not start immediately after removing your foot from the brake. The issue becomes greater the longer the engine has been running. On longer drive times, the engine hesitates enough that it seems like it might not start. The dealer has replaced the original starter due to the same issue. The new starter is less than 3 months old and the problem is again happening. No warning lights or indications that the engine will not start immediately upon removing your foot from the brake. The greater amount of time for the engine to restart has made pulling out into traffic when there is a clearing to pull out has become a safety concern as the pause is enough at times to now make the gap no longer large enough to pull out safely.

We were driving on a major highway today and the sunroof of my Subaru Crosstrek randomly exploded with a loud bang. Glass shattered everywhere in the car, covering us passengers with shards. Thankfully no one was hurt and we were able to pull off safely and remove the shards from our clothing and seats, but I could easily see this situation causing significant harm if it were to happen again. I have photos and my vehicle is available for inspection. A simple google search reveals that there are tons of people with Subarus who have had the same experience with a randomly exploding sun roof. The vehicle has not yet been inspected by the dealer or manufacturer but I am bringing it in ASAP. The car is 1 year old and there were no symptoms of the problem prior to failure.

bought the car last week and I got a crack on the windshield from a small rock. I did an insurance claim that I have an appt for next Wednesday and while driving to work another pebble hit the windshield. So the first crack has not even been fix and I got another one. In my years of driving I have never had this issue.
Electrical system, Vehicle speed control, Fuel/propulsion system, Jan 29, 2023, crash
I was driving my 2021 Subaru Crosstrek slowly in a parking lot when it unexpectedly accelerated on its own without me pressing the gas pedal. I believe the Crosstrek was now going 40mph. I tried to shut off the engine and brake at the same time but neither one had any effect. I thought maybe I had two options. Either hit another vehicle or pedestrian or turn my car into the curb. I decided to turn into the curb which resulted in the breaking of both axels, flattening all the tires, and sustaining damage to the front fender and headlight. The car was then towed to a garage we’re it was declared totaled. I checked the internet to see if this had occurred to any other Crosstrek. It turns out their is a class action suit pending for the same reason. Police records will show I was not drunk, sleeping, and the car mat was off gas pedal.12

Spontaneous windshield crack. No impact or apparent cause. Available for inspection. Based on online research and your database, this is a common occurrence. Reporting to Subaru dealer has been initiated.

My brand new Subaru ignited in the engine compartment, burst into flames and exploded while I was driving it.
Service brakes, Nov 6, 2022, crash
In the winter of 2021-22, while parallel parking, backing up, then pressing the brake, my Crosstrek spontaneously accelerated in reverse and rammed into the truck already parked behind me. The Crosstrek paused, then rammed again, as I pressed harder on the brake. I put the car into “park” and turned off the engine. I was baffled and had no explanation for what happened. Thank goodness a person wasn’t between my Crosstrek and the truck. More recently, on October 4, 2022, I was at the post office mailbox drop-off. My Crosstrek was stopped with my foot on the brake. Some mail had fallen out of the overstuffed mailbox, I opened my door, set my foot outside, leaned over to pick up the mail, and my Crosstrek spontaneously accelerated forward. My car door hit the cement pylon and closed on my leg. The car lurched forward again, then stopped, and I was able to open the door. My leg was broken with a compound fracture and my foot was nearly ripped off. I called for help, 911 was dispatched, and I was rushed to the hospital in an ambulance.

Sunroof exploded outward, the majority of the glass was blown away. The sunshade was open. The temperature was 56 degrees. I was traveling north on I 15 in Davis Couty, Utah. I was not injured, there were no other occupants. I drove to Subaru dealer, they said they have seen this before, only one case. It was inspected by service dealer and deemed safe to drive with sunshade closed. There were no warnings, the sunroof is used infrequently. There were no other objects on the roof.

Windshield is very fragile. (I think it cracks when a flower petal falls on it...) But seriously, I have about 20 chips in my windshield and have not had any significant boulders or trucks with rocks that have hit my windshield. It appears to be from every day urban commute, which is unusual. I have never had a car that I have had to replace the windshield in due to fragility. Also, the windshield seal has come completely off at the base near the hood.

The front window was hit by chips seal pebbles from the car in front of us and chipped the window, twice. It was repaired with standard window chip repair.

Had intermittent total loss of power for about 1/2 of a mile.
Electrical system, Aug 25, 2022
The contact owns a 2021 Subaru Crosstrek. The contact stated that the battery was drained quickly, causing the battery to need frequent recharging. The vehicle was taken to the dealer where it was diagnosed that the battery needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that the replacement was not covered under warranty. The failure mileage was 1,300.

The bluetooth system is not functioning properly. When a call is in progress, the bluetooth will indicate that no phone is connected and prompt the driver to connect the phone. In the meantime, the call is still active and the person on the other end hears the radio playing but the driver cannot hear the other person. The call will then reconnect for a few seconds before repeating this process. It will continue until the call is ended. While this might be considered an inconvenience, I believe it is a genuine safety issue as this problem takes the drivers eyes off the road and has them answering prompts on a visual screen and is a general distraction. Subaru is aware of the problem and has refused to take action to correct it. The incident is ongoing. As a result the hands-free phone option is unavailable.
Visibility/wiper, Jul 24, 2022
Windshield seems pretty fragile after being hit by a little gravel pebble due to construction work at the highway the crack extended in less than 24 hours to 12 inches. This is very concerning since it’s pretty weird to a chip to develop as bad as this one.
