NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2021 Subaru Crosstrek. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
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.
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)
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.
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.
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.
The contact owns a 2021 Subaru Crosstrek. The contact stated that while his daughter was driving at an undisclosed speed, the vehicle inadvertently lost motive power in the middle of the roadway. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the battery. The vehicle was repaired, but the failure reoccurred. The vehicle was towed to the dealer and diagnosed with head gasket failure. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 120,000.
P26A5 code came on after driving a little over 200 miles. It went off at one point but came back on and has not gone off.
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.
Rear rotors delaminating at 33000 miles
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.
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?
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.
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).
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.
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)
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.
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.
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
While driving down the freeway, all the warning lights came on and the engine sputtered and cut out. As we were in the left lane on a busy freeway, it put us at considerable risk. We were able to get to the left shoulder and get towed off the highway. This was caused, I later learned, by a faulty electronic thermostat which caused the system to fail.
Suddenly warning light "Check Engine" came on along with Eye Sight malfunction warning. "i RAB off" "Check Engine" Automatic Emergency Braking not working. Yes, available for inspection. Not confirmed yet by dealer. It is the weekend. There were no unusual symptoms prior to ADAS malfunction.
Subaru Eyesight system engaged randomly with no forward obstacles. Dashboard lit up, signaled alarm, and brakes engaged causing the car's nose to bottom-out. This has happened twice, thankfully at low speeds and thankfully without another car rear ending me. I'm worried this will happen on the highway. Eyesight system is generally unreliable. Random lane departure warnings and obstacles detected where there are none.
This is not specific to the Crosstrek. Subaru's remote connect app "mysubaru" has a dangerous flaw. When buying a vehicle pre-owned, the previous owner may still have access to the car. Subaru's call center says it takes at least 5 business days for a "transfer of ownership" process to occur. More often, customers never gain access to their pre-owned Subaru. The main cause of concern is that the previous owner may still have access to remote start the vehicle! Imagine you park your Subaru in your garage overnight, just for someone to start it remotely. Carbon Monoxide is borderless and colorless! This problem will eventually KILL someone!
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.
Airbag shows OFF even when passenger is seated.
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
This is my 3rd Subaru. This one has now has 3 windshield cracks. 2 spontaneous, one by a tiny pebble. The photos are all from this one vehicle.
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.
In early November 2023, NHTSA Recall Number23V755000 was issued for my 2021 Subaru Crosstrek. I was not notified by NHTSA or Subaru even though none of my contact info has changed since buying this new vehicle. I believe that this creates a potential safety issue if owners are not made aware. I found out through Carfax in early January 2024.
Check engine light came on while driving. All Advanced Driver Assistance Systems were disabled. Code is P26A3: Thermo Control Valve is faulty. This is a known problem and Subaru has addressed it by redesigning the Thermo Control Valve in 2021. Unfortunately there is no recall on the models fitted with the prior design that have a high rate of failure.
The contact owned a 2021 Subaru Crosstrek. The contact stated that while parking and the brake pedal was depressed, the vehicle accelerated unexpectedly and collided with a wall. The collision was at the front of the vehicle. The air bags deployed. The driver sustained arm, leg, thumb, back, and nose injuries. Medical attention was needed. A police report was filed. The vehicle was towed to an impound lot. The manufacturer was not notified of the failure. The failure mileage was approximately 1,300.
******* DELETE VOQ ******* THIS COMPLAINT IS BEING MARKED FOR DELETION BECAUSE IT IS REQUESTED BY THE CONSUMER THAT THEY WISH TO HAVE IT REMOVED. DJR ******* DELETE VOQ *******
The issue is the Engine Coolant Bypass Valve. This causes the Engine to not take in as much coolant resulting in the engine getting much hotter than it should, thus putting those in the car’s safety at risk. This could ultimately lead to a fire and/or cause the car to suddenly lose power. My car already refuses to go above 3000 rpm’s and is very laggy when driving. The car itself shows a code that the bypass valve needs replaced & the check engine has come on. However, Subaru has failed to acknowledge that this is an issue amongst most of their vehicles since 2020. This issue also disables the Subaru Eyesight which is in control of adaptive cruise control, pre collision breaking, and sway warning. With those features now disabled, the car has lost the Safety Package that Subaru boasts. I have read on many online forums that this has been an ongoing issue now for many customers, a bulk of which experienced total engine failure. This lack of responsibly is putting many lives at risk on the road every day. I hope this helps shed light to this issue to Subaru & that this part is recalled so that Subaru must pay for the repairs instead of the car owners. Also, the repair part is around $500 & maintenance must be done by Subaru which is another $400-500 for labor. My opinion is they are using this defect as a way to make easy money on many customers since 2021. Here’s a link to the Service Bulletin that has been created about this issue: https://static.nhtsa.gov/odi/tsbs/2022/MC-10208664-0001.pdf?fbclid=IwAR355WNLzftp3Qhmj7GnfmPFL9VODbDEbiT9X5Admr7n90YI4rTa4J5HSIk_aem_Aex4JIYKdhZ3n6Xh90f9w4zKu4TxFSO6LxpMIwO79FtzP1E3Y5TygVIAq_Ih4KxM6nc
There are occasional times (perhaps once or twice a month) where the vehicle does not respond with the expected acceleration of a depression of the accelerator pedal. Specifically, the vehicle "lags" when I depress the accelerator pedal. While I have not experienced a dire situation or collision because of it, I believe it might cause other drivers to experience a safety incident: a driver might want to perform a fast maneuver with elevated risk but not receive the expected acceleration. For example, I was once making a U-Turn with traffic oncoming about 2,000 feet away. I needed to make the maneuver swiftly but my vehicle lagged. I would like to report this issue in case other owners of the Subaru Crosstrek Plug-In Hybrid are also experiencing.
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.
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
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
