Each component in detail
What the reports in each category say, in the owners' own words
Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Turned on defroster to clear window fog, window cracked along bottom of windshield about 3-4 inches from bottom along 2/3 the length of the windshield. No prior chips or scratches existed.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
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.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
- 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.
Thermo Control Valve (TCV) causes a check engine light to come on and disables eyesight issue started May 29, 2026. The check engine would go on and off. Now it just stays
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
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.
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.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.

Viscous Coupling and center differential failing. unable to turn at low speeds. Low mileage vehicle, under 40,000. This is a several 1000$ repair that happens right after warranty
Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
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.
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.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
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
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

From owner reports, verbatim
While the vehicle is moving. There is a loud pop noise from under the car. Subaru of America said it is a weld that is cracked. This pop noise is also felt in the steering wheel.
The windshield cowl is greatly separating at the bottom where it meets the wipers. The windshield and cowl are factory and no replacement or alterations done during the life of the car. I am the only owner

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
The contact owns a 2021 Subaru Crosstrek. The contact stated while driving at various speeds, the steering wheel was difficult to turn in either direction. Several unknown warning lights were illuminated. In addition, the contact stated that the vehicle was repaired under an unidentified recall; however, the recall repair failed to prevent a failure. The contact stated that upon further inspection, the vehicle occasionally experienced an abnormal battery energy consumption, although the battery was previously recharged. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.
I just leased a new '21 Crosstrek Limited. With only 90 miles on the car, while driving on the highway using the adaptive cruise control and lane keep assist, the vehicle started aggressively jerking over towards semi trucks (while going 70mph)- I had to give significant input to not be pulled into a semi truck. I turned off the feature then turned back on. Again, it was hard jerking only towards semi trucks. Drove back to the dealership. Their mechanic took for a drive and said the exact same thing, that it was "sketchy" and jerking towards semi trucks. It was suggested I bring back if the "condition persists" which would mean risking a fatal collision with a semi. I contacted the GM of the dealership and explained what was happening and he said to being back again and they'd get a field tech from Subaru to test. Their service manager test drove and noted the same thing, as did the field tech. "Severely pulls to the right as trucks pass. Test drive vehicle and found that when using lane centering, vehicle is quite jerky and pushes towards centerline, especially when larger vehicles like a semi trailer is present. Recommended calibrating eyesight camera and test driving again". They calibrated the Eyesight and I picked back up. Drove back on the highway and turned on LKA, this time the steering was completely taken over and jerking all over the lane and flashing telling me to keep hands on the wheel when both hands were very tight on the wheel. It's continued to jerk all over while using lane keep assist and when I try to override the steering to avoid a collision the wheel feels like it's fighting me. It's extremely dangerous. The car now has 300 miles and I'm terrified it's going to kill me and it's putting everyone on the road at risk. I had the same tech in my '19 Impreza Limited and didn't have a single issue. I fear there is a serious defect with the Eyesight and LKA. No codes are present. They said vehicle is operating as designed, it's now more more erratic

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
The contact owns a 2021 Subaru Crosstrek. The contact stated that while driving at undisclosed speeds and turning to the right or the left, the steering wheel and the vehicle were shaking and vibrating abnormally. The vehicle was taken to the local mechanic to be diagnosed, and it was determined that the control arms and struts needed to be replaced. The vehicle was not yet repaired. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not notified of the failure. The failure mileage was approximately 85,000.
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.

Transmission
Reports naming the automatic or manual transmission, including shifting behaviour, shudder, slipping and transmission control modules.
From owner reports, verbatim
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?
Transmission was about to fail. Car started making noise at low speeds in drive and reverse about 2-3 weeks ago, so I brought it in and mentioned the noise to the service advisor. There were no warning lights, messages on the dash indicating a problem. Confirmed by a Subaru dealer as needing to be fully replaced.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
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.
Rear rotors delaminating at 33000 miles

DRIVING HOME IN DAYLIGHT AFTER TAKING DELIVERY OF 2021 SUBARU CROSSTREK PREMIUM ON 1/29/21, I RAISED DIMMER SWITCH TO HIGHEST POSITION TO ILLUMINATE DASHBOARD BECAUSE I COULDN'T SEE SPEEDOMETER/INSTRUMENT PANEL, AND THERE WAS NO ILLUMINATION! THIS IS MY 3RD CROSSTREK PREMIUM SO I KNEW HOW THE DIMMER & LIGHTING CONTROLS WORK. I CONTACTED DEALER & SERVICE MGR IMMEDIATELY, WAS TOLD "IT IS WHAT IT IS, NOTHING CAN BE DONE, SENSORS CANNOT BE ADJUSTED!. AFTER NUMEROUS COMMUNICATIONS W/SUBARU THROUGH LAST MONTH, THEY WILL NOT ACKNOWLEDGE, NO LESS ADDRESS, THIS DESIGN FLAW THAT MAKES THE VEHICLE UNSAFE TO DRIVE. THE SUBARU OWNERS FORUMS CONTAIN THE SAME COMPLAINTS ON VARIOUS MODELS AS WELL. I'VE ATTACHED FIRST SET OF EMAILS TO SUBARU STARTING IN FEBRUARY 2021 AND A SET OF EMAILS ENDING LAST MONTH. I ALSO FILED A COMPLAINT UNDER LEMON LAW TO NYS ATTORNEY GENERAL KNOWING I DIDN'T MEET THE REQUIREMENTS BUT FILED IT TO GET IT ON RECORD; BECAUSE IT WAS DETERMINED TO BE A DESIGN FLAW & NOT REPAIRABLE, COMPLAINT WAS REJECTED. HOPE YOU CAN HELP ME AS SUBARU WOULD NOT ALLOW THE CANCELLATION OF MY LEASE EVEN THOUGH THEY KNEW OF THE PROBLEM BEFORE CAR WAS SOLD AND WERE ADVISED BY ME OF THE PROBLEM WITHIN 1 DAY OF TAKING DELIVERY. THANK YOU.
