| May 2026 | POWER TRAIN,ELECTRICAL SYSTEM,ENGINE | On [XXX] ~[XXX] PM, at highway speed on [XXX] eastbound near Frisco, CO (a mountain interstate), returning to Denver from Salt Lake City, my 2021 Subaru Crosstrek suddenly and without warning dropped into reduced-power limp mode and began lurching and shaking while the engine kept running. I lost the ability to accelerate or maintain speed. At the same moment the check engine light came on and multiple active safety systems automatically disabled: EyeSight, pre-collision braking, vehicle dynamics (traction/stability) control, and hill start assist. It took about two minutes to manage the lurching, power-limited vehicle across multiple lanes of traffic to reach the shoulder. My partner was in the vehicle. Had this happened on a bridge, a grade without a shoulder, a tunnel approach, or in heavier traffic, I believe a collision was a realistic outcome. The vehicle was towed to a Subaru dealer and diagnosed with a failed Thermo Control Valve. Sixteen trouble codes were stored, including P26A6, P0606, P060B, P2138, P2135, P2122, P2119, P2004, P2005, and P0191. Mileage was 49,983. There was no prior symptom. The vehicle had a full multi-point inspection at the same dealer only 11 days and ~1,400 miles earlier ([XXX]); nothing was flagged. This failure mode is already known to Subaru, addressed by Technical Service Bulletin 09-119-24 and a warranty extension to 15 years/150,000 miles; the dealer repair order confirms the TSB. I am concerned Subaru handles a safety-relevant failure, one that disables collision-avoidance systems at highway speed, through a quiet warranty extension rather than a recall or owner notification. Owners get no warning and discover it only when it fails dangerously. I request NHTSA open a formal safety defect investigation.

| May 2026 | ELECTRICAL SYSTEM | Purchased in August 2024, had to get a new battery 2 days after purchase & then went to the dealership January 2025 because my battery kept dying & I was stranded at the airport late night. They acknowledged is has a parasitic draw but did not notate the source. They claimed I needed a new battery when my previous Subaru branded battery was only 5 months old. The new battery was almost $600 which is double/ triple a store branded equivalent. I purchased yet another battery but non-Subaru branded since theirs did not last even 6 months. Still have been experiencing the same issue. I pulled the dcm fuse and let my car sit for several days as a test. The battery did not die with the dcm fuse removed. The front speakers and Bluetooth are linked to the dcm fuse so they do not work if it is unplugged. | Crash: No Fire: No | Unknown |
| May 2026 | UNKNOWN OR OTHER | Subaru Starlink alerts keep disrupting my navigation so it’s making driving unsafe bc it pops up and interrupts Waze Navigation and has to be addressed to get back to my map. It happens incessantly and persistently even though I’ve turned off app Starlink access and alerts. It is a distraction to my focus while driving and i fear it will cause me to get into an accident. Why hasn’t Subaru fixed this known issue? | Crash: No Fire: No | Unknown |
| May 2026 | UNKNOWN OR OTHER,LANE DEPARTURE,BACK OVER PREVENTION | Power train automatic transmission park/neutral start interlock Reverse lights not illuminating increasing risk of collision Recall was issued not listed here WRQ-23 Recall issued 1/8/23 My issue started in 2026 off and on Why is this Recall not listed Subaru service department states not able to provide service without the recall on file Car purchased August 2025 | Crash: No Fire: No | Unknown |
| May 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | The car in front of me was about a two car's lengths away. It was very cold and that car's exhaust plume was larger than normal. The exhaust plume was highlighted by sunlight, and I believe my car thought it was an object. The auto braking system alerted and immediately slammed on the brakes in the middle of heavy traffic. There was no time for me to respond. Thankfully no one hit me. If I'd been on the highway it could have been catastrophic. The problem has not been reproduced or inspected. | Crash: No Fire: No | Unknown |
| Apr 2026 | ENGINE | The vehicle shuddered violently when turning the ignition, and then failed to start entirely. The mechanic found that the engine coil was severely damaged, no external influence, just that it had become worn out remarkably fast. The vehicle has less than 60,000 miles and just 5 years in service. The repair will end up costing about 1500 with tows included and the vehicle has not gone without maintenance or care. | Crash: No Fire: No | Unknown |
| Mar 2026 | BACK OVER PREVENTION | The backup camera on my Subaru Crosstrek started to a stop working a few weeks ago. It first started to intermittently transmit a video feed that was fuzzy and the colors were completely incorrect. That started to follow with the camera not working about half the time at all on my head unit. Now it's completely not showing up at all on my head unit when I go into reverse. I live near a school and when I back out, I'm concerned that I won't be able to see a child behind my car. Same for parking garages and parallel parking. The Subaru dealership is saying they have checked all the wiring and modules and have isolated it to the backup camera. There were no other messages besides the camera starting to malfunction. | Crash: No Fire: No | Unknown |
| Feb 2026 | UNKNOWN OR OTHER | While driving 65mph on the freeway the front passenger window imploded into the car. This threatened the safety of both the driver and passenger as the glass flew at such high velocity it ended up in both occupants clothes, hair, and skin, the glass also was found as far as the trunk. This endangered the safety of others driving on the highway as the driver was shocked and caught off guard at the sudden implosion. The problem has been found in similar model subaru's including examples of moonroof and rear windshield implosions. The vehicle has been inspected by the local dealer yet they are claiming to have found no abnormalities in the window systems, but are unable to ensure that the glass was tempered properly. There were no symptoms of the problem prior to failure. | Crash: No Fire: No | Unknown |
| Feb 2026 | VISIBILITY/WIPER | On Friday evening, [XXX], while closing the rear driver-side window, I heard a loud mechanical snap, after which the window failed to operate. The window regulator has binding issues (as documented in Subaru TSB 07-189-21R). This mechanical binding disables the anti-entrapment (anti-pinch) safety feature. The sensor is bypassed by the binding/mechanical failure, the window will not reverse when it hits an obstruction. This creates a direct entrapment and crush risk for passengers, specifically young children. A Subaru Customer Advocacy Manager (Jennifer) admitted on a recorded line that “the part should not break” (Case #[XXX]). Despite this admission and the documented safety risk, Subaru of America refused to authorize a safety repair. The failure was inspected and confirmed by an authorized Subaru Service Center (Walser St Paul). No warning lights appeared prior to the failure as it is a pure mechanical defect. I have the recordings, but I’m not able to upload them at the moment. Please let me know if needed.

| Nov 2025 | FORWARD COLLISION AVOIDANCE | Traveling at speed of 30MPH. A tocoma truck in front of me suddenly stopped in road lane. Driver said that his vehicle made an auto assist stop were the brakes lock. My 2021 Crosstrek eyesight/braking system failed. I saw the truck stop but the system failed and I went into the back of a large truck. There is a witness who is happy to talk with you. He saw the truck's sudden stop and my crosstrek failure to stop. My car is totaled. I have the police report and have reported this to my insurance company. | Crash: Yes Fire: No Towed | Unknown |
| Oct 2025 | SUSPENSION | Both front lower control arms have damaged bushing discovered at 48,840 miles by my mechanic. Took to local dealership on 8/16/25 and they claimed per TSB from Subaru for cracks that although it had cracks, it was not necessary to be replaced due to it not being cracked enough. Brought back to my mechanic on 9/26/25 and cracking is worse, odometer is at 56,763 miles now. This part is supposed to last around 100,000 miles. Premature cracking puts me at risk of losing control of my car should the parts fail. | Crash: No Fire: No | Unknown |

| Feb 2025 | POWER TRAIN | I just recently had my car come out of park while running at the top of a steep hill. I had stepped out of my car to deliver paperwork to my client. I walked to and from my car approximately 75-80 ft. As I was approaching my car I heard a clicking or a release sound then it began to roll. I wasn’t close enough to stop it and it rolled down a neighbor of my clients driveway and eventually rolled over landing against a tree. When I arrived at my car it was still running. I have awd and I noticed the tires in the air were not turning as they should have if it was in drive. My car was obviously totaled. How do I have someone check my car to see if there was defect that caused it to come out of park? I must say I forgot to set my handbrake. But I feel the car should not have come out of park regardless. Could it have been the front axle shaft or anything else? | Crash: Yes Fire: No Towed | Unknown |
| Feb 2025 | SEATS | Driver seat began rocking. The dealer indicated it’s a problem they saw with other cars as well. The attachment to the rail you move your seat forward and backwards with, brakes. The dealer wants to sell you new brackets to make your car safe again. | Crash: No Fire: No | Unknown |
| Feb 2025 | POWER TRAIN | I was experiencing a weird binding or lurching in my drive train which made my Subaru feel unstable. I am a mechanic so I investigated these symptoms online and found that a large number of Subaru owners with manual transmissions were experiencing the same issue......a failing viscous coupler was the issue. There were no warning lights or indications prior to failure A failing viscous coupler will not properly engage the front wheels when needed, causing reduced traction in slippery situations, increasing the risk of sliding or spinning out. Uneven power distribution: When a viscous coupler fails, it can lead to uneven power distribution between the front and rear wheels, potentially causing the vehicle to pull or jerk, especially during turns. Sudden engagement: In some cases, a failing viscous coupler might engage too aggressively, causing a sudden jolt or shudder, potentially leading to loss of control. I purchased and replaced this component at my own expense not knowing the magnitude of the issue. This is a definite safety issue that could lead to serious injury or even death. I have the old part in my possession, it failed around 85,000 miles. One of the mechanics in the Subaru forum said he had submitted a report to NHTSA but I didn't see anything on your sight. Thank you for your help. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Nov 2024 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | What component or system failed or malfunctioned, and is it available for inspection upon request? The USB A outlets under the head unit that allow connection to Android Auto and Apple CarPlay Yes it is available for inspection upon request How was your safety or the safety of others put at risk? The connection when hooked up to a phone is intermittent. This results in driver distraction whenever it disconnects due to trying to get it to reconnect. Especially when using gps apps this means the driver may be "lost" until it can be reconnected, which means they will try to get it reconnected while driving which is dangerous. Sometimes it goes in and out every 60-90 seconds. Sometimes it won't connect at all until the vehicle is power cycled or the head unit is reset but neither of these guarantees a stable connection. The issue is not fixed by replacing the USB cable or the phone with a brand new phone. The cables and phone do not have this issue with any other USB port that they have been used on (in other vehicles). Has the problem been reproduced or confirmed by a dealer or independent service center? Not on my vehicle but there are hundreds of reports online for years with multiple Subaru models where it has been. I could get it reproduced easily, just haven't had the time. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No This happens every day, at any speed, and has been happening since I got the vehicle at 20000 miles and there are 35000 miles on it now (approximately). | Crash: No Fire: No | Unknown |
| Nov 2024 | ELECTRICAL SYSTEM | The contact owns a 2021 Subaru Crosstrek. The contact stated while driving at an undisclosed speed, the vehicle shut off unintendedly and failed to restart. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer where it was diagnosed and determined that the battery had failed. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 27,000. | Crash: No Fire: No Towed | 27,000 |
| Oct 2024 | POWER TRAIN,ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | Check engine light came on while idling. "Eyesight" tech turned off along with certain associated safety features. Next day, vehicle struggled to ignite. Came to a complete stop at an intersection, released brake, stepped on gas, and the car rolled forward as if in neutral and bucked up and down like a rodeo bull. | Crash: No Fire: No | Unknown |
| Aug 2024 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | While driving in the left lane on a three lane highway (about 70mph) the car's automatic braking system engaged. The car would not accelerate creating a very dangerous situation on a congested highway at night. Luckily, we are able to navigate to a brake down lane without a collision. The check engine light, Eyesight light and RAB light turned on. The car would not function normally and was towed to a Subaru dealer (Patrick Subaru, Shrewsbury MA). Diagnosis was a failure of the Engine Coolant Bypass Valve P26A6. Other failure codes were: P0087, P2004, P2005, B2806, B2C22. I was told this is a known problem in Subarus of certain years, but, instead of recalling, the company has extended the warranty on the malfunctioning part. This incident happened without any previous warning and caused a life threatening situation for us and those around us. | Crash: No Fire: No | Unknown |
| Jul 2024 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM | On two incidents randomly and without warning the car failed to accelerate while driving in traffic on an open road and I had to coast to safety and put in park, then drive, then travel less than five miles home. Both times I immediately scheduled service with suburu with appointments about a week out. The car drove without incident while awaiting service. Service failed to replicate the problem, diagnose or remedy it after having the car a week and I was told“vehicle is operating properly at that time”. The second occurrence at the end of June was far more dangerous as I was traveling at a higher speed in heavy traffic on a multi lane road when it occurred Car is unsafe for me, passengers and other drivers. I risk being stranded. I have no sense of reliability or safety and the car is just now at 30k | Crash: No Fire: No | Unknown |
