Vehicle's Auto Start-Stop system shut the engine off while stopped at a red light in [XXX], in rainy conditions in late XXX at approximately 29,000 miles. When the brake was released after the light turned green, the engine did not restart, leaving it stopped in the travel lane in live traffic. The driver had to use a portable jump starter to get it running again. This was not isolated — repeated failure-to-start incidents in prior weeks had already prompted carrying a portable jump starter in the vehicle. At the time we believed this was a failing 12V battery. The original battery was replaced XXX with a new aftermarket AGM battery. Despite that replacement, the vehicle has continued to have multiple complete battery drain if left parked for multiple days (but less than a week), indicating the restart failures were likely caused by an underlying parasitic electrical draw rather than a simple worn-out battery. Subaru's own Technical Service Bulletin 07-199-21R, "Measurement of Dark Current (Standby Current Draw)," describes this exact failure pattern (batteries/vehicles going dead over time due to standby current traced to the VDC module and/or Power Rear Gate control module) for this model and model-year range. A pending federal class-action lawsuit, [XXX] v. Subaru of America, Inc., Case No. XXX (D.N.J., filed XXX), alleges an electrical-system defect preventing one or more control modules from entering a proper low-power sleep state, causing parasitic battery drain, and sp

Good Day! I bought my 2021 Subaru Outback XT Onyx in Jan 2021. I had waiting 6 yrs for Subaru to use the Turbo Motor in the Outback again. I've had this car for 5 years with my warranty running out Jan 2026, but I only drive 5000-7000 miles per/yr. Current odometer is 29,901 miles. At my most recent oil change service at the Dealer, they showed me a video of my cars drivetrain from underneath. There were two bad seal leaks. One at the transmission pump housing and the other at the Upper Oil Pan. I had been there for an oil change a year earlier for the same service and there was no mention of these issues! After speaking with the service advisor, he said to call Subaru Customer Advocates. They listened to my situation and a few days later offered a $1400 credit for a $4000 job that involves the removal of my cars engine (upper oil pan) to replace it because it's bolted to the frame there. The other leak seal involves dropping the transmission. These are major repairs that following will dampen my ownership experience after decades of Subaru praise by Americans. I researched this issue online and found out there was a manufacturing defective regarding the silicone liquid seals they used for 2020-2022 Outback, Ascent, & WRX! This procedure was used throughout the driveline with the Turbo Motor & CTV Trans. There are 1000s of accounts of this defect placing burden on the owners of these cars who bought them in good faith. I did the research, called the dealer & Subaru with the d

I am reporting a serious and intermittent steering safety issue with my 2021 Subaru Outback. On two separate occasions, the vehicle suddenly lost what appeared to be power-steering assistance while the vehicle was in motion, causing the steering wheel to become extremely difficult to turn. The first incident occurred while I was driving on the highway and going down a ramp. The steering suddenly became extremely difficult to operate and a warning symbol illuminated on the dashboard. I was able to maintain enough control of the vehicle to safely pull over to the side of the road. I turned the vehicle off and restarted it, and the warning light disappeared and normal steering operation returned. The second incident occurred while I was making a turn into a neighbor. The same problem occurred: the steering suddenly became extremely difficult to turn and a warning light appeared on the dashboard. After turning the vehicle off and restarting it, the steering returned to normal. The intermittent nature of this problem is concerning because restarting the vehicle temporarily restores normal steering, but the failure has now occurred more than once without warning. One of the incidents occurred while traveling on the highway, creating a significant risk of loss of vehicle control and a collision. I am concerned that this may involve the vehicle’s electric power-steering system or related electrical components. I am reporting this to NHTSA because a sudden loss of steering assistance

My 2021 Subaru Outback suffered a failure of the Oil Control Valve (OCV), a sealed Subaru component with no maintenance interval, no inspection procedure, and no preventative service. This failure allowed engine oil to migrate into multiple wiring harnesses and modules, causing extensive electrical contamination. This is not normal wear and tear. It is a latent defect in a Subaru component. Due to the failure of this sealed component the Subaru dealership and a second independant shop have recommended replacing the entire electrical wiring harness at over and estimated $15,000. Even if the entire harness is repalaced the extensive contamination may find its way into electrical connectors even after replacement of the harness. The fact that this contamination was so wide spread, and there were absolutly no warnings that indicated the widespread contamination is alarming. I guess the thought is that different electrical components could just stop working. This seems like a serious safety concern. It is impossible to know how long the contamination was spreading through the car since there are no errors or warnings that indicated an issue.

I was already parked in a spot in a public parking lot. I tapped the accelerator pedal to move the car a few inches. The vehicle responded by violently accelerating, hitting a vehicle directly in front of me in another parking space. I applied my brake but the car would not stop. The force of the acceleration pushed the car out of the it's spot and it hit a curb and tree appox 30 ft away. In defensive move I turned my wheels to the right and continue to try and brake. This caused my car to hit the car on the right side of me. Property Damage occured. No injuries. Vehicle defect.

First battery drain in car. Bought a new battery and it drained again for the second time. Called Suburu to ask about a parasitic drain from the DCM and they said it was likely that and told me to call Suburu America. Did that but they wanted me to take it to a Suburu dealer to get the problem verified. I don’t have the $ to do that. I notice there is a class action in court right now for this exact problem.

We are VERY concerned about the failure of some very important safety features of our 2021 Subaru Outback Touring Edition. We were involved in a bad car accident caused by a person under the influence who was in handcuffs when we were taken away by ambulance. As you can see by the photos, there was MAJOR damage to the other car and significant damage to ours. What is most concerning is the fact that NONE of the airbags deployed and the safety and security plan also failed - it did not call 911. I had to find my phone on the floorboard and call 911 myself. I am not sure if the insurance company will call it a total loss but I really don't think I want the car back BECAUSE of the failures of these very important safety features. I truly feel like Subaru has some explaining to do on this.

I am filing this complaint regarding multiple serious safety defects in my 2021 Subaru Outback purchased in July 2021, currently at 48000 miles THERMO CONTROL VALVE FAILURE (26,307 miles) While traveling in the center lane on [XXX] southbound in [XXX] the evening of 1/6/2024 my vehicle suddenly experienced a complete loss of control. It seemed that the car was accelerating and braking at the same time without driver input making it impossible to operate safely. It started shaking and several lights were illuminated on the dashboard, power steering was not working. The car coasted to the right shoulder and starlink was used to call for help. The car was towed to the dealership for repairs. The diagnosis was a failed thermo control valve and related sensor circuit. There were no dashboard lights before the incident that fore shadowed this event. This failure rendered the vehicle completely inoperable at highway speed and posed and extreme risk to the safety of the driver, passenger and other motorists. I am aware that Subaru has extended the warranty on the thermo controls valve to 15 years/150000 miles for 2020-2022 Outback’s which suggests that Subaru had knowledge of the defect. Since the incident several other premature “wear” defects have presented under 48000 miles on a 2021 vehicle: - 41,402 miles: driver side rear strut replaced - 41,402 miles: rear brake pads and rotors - 41,402 miles: driver side front window motor, regulator and run Chanel - 41808 miles: rear knuckle

The failure involves the engine (powertrain), which was under warranty. The vehicle has experienced four catastrophic engine failures resulting in sudden loss of power, including at highway speeds (65–75 mph). The most recent failure also involved an oil-saturated catalytic converter. These failures occurred between 06/25/2024 and 03/16/2026. During this ~629-day period, the vehicle was only in my possession for about 184 days, as it remained at the dealership for diagnosis, repairs, and repeated engine replacements. The issue remains unresolved. The vehicle is currently in my possession, available for inspection, and is not being driven due to safety concerns. All failures occurred during normal driving and caused sudden loss of power with no prior warning, leaving the vehicle inoperable and stranded. This created a significant safety risk due to inability to maintain speed or safely merge, increasing the likelihood of rear-end collisions. The failures have been confirmed by an authorized Subaru dealership, with multiple engine replacements performed under warranty and most recently as a goodwill repair. Both the dealership and Subaru of America have acknowledged they cannot determine the root cause. The dealership’s Operations Director stated the vehicle is not safe and he would not allow his family to drive it. The vehicle has been inspected multiple times by the dealership and Subaru of America. However, no inspection reports, diagnostic data, or detailed findings have be

On 10/29/25 the car lost power once it got to 3500rpm. Multiple warning lights came on. On 11/06/2025, the Thermo Control Valve, high pressure fuel line, and gaskets for intake manifold and EGR were replaced. On 11/24/25, when backing up slowly in a small parking lot, the rear camera detection picked up a raised cement walkway with metal railing. The brake was applied by the driver, however the car accelerated quickly and slammed into the railing and cement. The vehicle was placed into drive after the collision and continued normally. The brake was on once the warning light beeped and prior to the collision. The foot was not removed from the brake pedal until it was in drive. It could not have been placed into drive without the brake pedal being pressed. I asked the dealership if they could pull data from the car at the time of the incident, and was told they weren't sure they would get any information. It has not been inspected by a dealership or insurance. There was no damage done to the cement and railing was already bent. Only the car sustained damage.

Thank God no one was in that lane. I had to get it replaced at Mid State Glass company. according to what I found on the internet this happens rather frequently. No notification by Subaru that this was even a possibility. I have the receipt the replaced sunroof and photos of the sunroof after it exploded.

SUDDEN AACCELERATION: Cold started the car in garage, all OK. Then backed out and into turn around where I placed foot on the brake. At that moment suddenly accelerated and engine revved to 2000rpm (sounded like). I had to push down very hard on the brake pedal (where my foot already was) to stop the car before crashing into a tree. Foot was clearly on brake pedal at incident (that was the only way I could stop the car). It was not on or close to accelerator pedal and no floor mat or other objects was on or near the accelerator pedal. Very concerned about safe vehicle with this sudden acceleration.

Reading this record

Complaint volume is well above typical for a single model year.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
