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 been provided despite repeated requests. Additional issues (including a broken axle and oil-saturated catalytic converter) were only identified during a third inspection after being missed previously. Requests for explanation were not answered, and further details were withheld as “internal.” There were no warning indicators prior to the first three failures. During the fourth, a temperature warning appeared only seconds before failure.

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.

While slowly backing out of a parking space, the vehicle suddenly accelerated on it's own - I do not recall pressing on the accelerator but the engine surged and the vehicle rapidly reversed and struck 4 other parked cars. It felt as if the accelerator became stuck and would not respond to braking. No warning light or dashboard alerts appeared. Subaru eyesight and adaptive cruise control were not engaged at the time. There was no known obstruction under the petals. This felt like a serious malfunction and could have caused serious injury. I am reporting this in case it is part of a wider issue affecting this model and because i see that there are multiple complaints to you about sudden unintended acceleration, especially during low speed maneuvers like backing out a parking space.

My vehicle is equipped with EYESIGHT. I was driving to my home after work at night and suddenly the infotainment system screen went blank; including Braking Assist, Adaptive Cruise control, Lane assist, Emergency Braking etc including Navigation, also the HVAC shut off and EYESIGHT that controls these as well, shut off. It was suffocating in the car due to no A/C and thusf I tried to pull over at a remote text-stop place and tried restarting the car but in vain. All screens were dark, no warm air, I couldn’t see what direction I was driving to, as well as I solely relied on navigation. I brought this car for it’s safety features and warmth in this cold temperature in UPSTATE NY and this happened. I waited for 20 mins, charged my phone for only 4-5% with a fellow citizen who was waiting there as well and checked online just to see a lot of people reported the same issue with 2021 Subarus with EYESIGHT. And there is NO way one can fix it. I tried contacting the dealer but in vain. I am afraid that if this would happen again, I wouldn’t be in a situation to face this scary experience.
