There have been multiple instances where my car has failed to “restart” if the auto-start-stop feature is on. I immediately turn that setting off every time I get into my car because if I pause for too long at a light/stop sign etc.the engine will stall and turn off (without being in park). I have reported this to Subaru on many occasions and they’ve told me to replace the battery, so I did, and nothing changed. I’ve also replaced the starter and that didn’t help either. I’m now unable to turn my car off at gas stations because I’m worried it won’t restart. I just saw that a law suit has opened because of this electrical issue so I wanted to formally report my concerns. This needs to be a safety recall.

SERVICE BRAKES — Filed 07/17/2026

We brought the vehicle in for routine maintenance. They reported that all brake hoses were bulging and at risk of failing at any time. They said that there was a related recall for a similar issue on other CrossTrek's but that ours was not included in the VIN list, so was not a part of the recall. This appears to be a serious component failure which could result in a fatal accident. The fact that this happened with all brake hoses indicates a defective component. We were lucky that we found it and were able to have it addressed before the brakes failed.

Was driving on highway when all of the lights on my dash illuminated. Eventually I got a warning for oil at temp alarm. Was giving code P2757 and P0700. Looks like this a common issue in Subarus but doesn’t look like it covers anything after 2020.

- Rod #4 failure of unknown cause, although there is speculation that current failure may be related to a major repair in oil system a year ago. - My safety along with my unborn child’s, husband’s and brother in law’s were all at risk. Another driver had to take evasive action to avoid hitting us in an active fast lane on I-70 going between 65-70 mph. There was no shoulder available to pull off on until a half mile up the road. - Yes the problem has been confirmed from the dealership partially. They did not identify a cause for the sudden failure. However stated it could not be determined if this failure is or is not related to a previous major engine repair made a year ago. - The engine has been inspected by the dealership and warranty company. - There were no warning signals prior to either engine failures. The first one being a year ago for head gasket failure that allowed oil to mix with coolant. With the most recent failure the engine ticked briefly after braking to merge for construction, the oil pressure light followed by engine light turned on 5 seconds before engine completely lost power.

The DCM on our 2021 Subaru Crosstrek is causing a parasitic drain on the battery. It left us stranded several times. We replaced the battery twice in the past 15 months. There is a class action lawsuit against Subaru for this exact problem, but they won't replace it on our vehicle because it has over 45,000 miles. A defective DCM is a widely known problem with many Subaru models. We never received notice of this problem from Subaru, nor were there any warnings, messages, or indications that this was a problem, until we took it to a mechanic for service, who sent us to a Subaru dealer because it had to be repaired by them.

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.

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.

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?

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.

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.

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.

We were rear ended on the interstate. Cars in front of us stopped and we also came to a complete stop and a few moments later we were hit. During the collision, none of the airbags were deployed. Both our front seats fully reclined backwards. None of our seatbelts locked. Only the two seats that no one was in locked. Also, my headrest completely broke off. Our car was later determined by the insurance to be totaled.

POWER TRAIN — Filed 02/07/2025

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?

Was driving on highway at approximately 65 mph. Check engine light came on. Engine started to stop responding to gas being given to car. Pulled off to exit highway approximately 1 minute after check engine light came on. At bottom of exit, car completely lost power. Attempted to put vehicle into park and wouldn't shift. Started to see smoke coming from engine and then shortly after started to see flames coming from engine. Immediately exited vehicle and called 911. No one was injured. Subaru indicated fire started as result of external influences. Insurance company's 3rd party auditors were not able to determine cause of fire.

FORWARD COLLISION AVOIDANCE — Filed 07/30/2023

While driving on the highway in the slow lane (furthest to the right), traveling at approximately 50 mph, I came to be behind a tractor trailer. Before I had a chance to pass the tractor trailer, it switched lanes abruptly. My vision past/beyond (in front of) the tractor trailer was heavily obstructed by the massive vehicle itself, so I could not see that in front of the 18-wheeler there was a mid-size sedan traveling at approximately 5-10 mph in the same active highway lane I was in. I had almost no time to react, and neither the Automatic Emergency Braking system nor the Forward Collision Warning system engaged. Both of these systems should have activated to prevent the collision and/or minimize injuries and damage. I subsequently collided (harshly) with the aforementioned sedan.

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

SERVICE BRAKES — Filed 10/04/2022

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.
