2021 Subaru Crosstrek Problems & Owner Complaints

Visibility/Wiper 29

“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 “th…”

“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 cl…”

“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.

“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 i…”

Forward Collision Avoidance 14 2 crash 1 fire 2 injury

“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 Wa…”

“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.

“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 t…”

“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.”

“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 "c…”

“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.”

“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 t…”
