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 Dea…

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 discovery & overall complaint! I asked for 80% to 100% help with these repairs because how many more will I have to deal with after these two are repaired??? I have received zero responses from either after expressing that this was a known defect, Bullitens went to all the dealers, nothing was mentioned to the owners, and they've just covered those cars still under warranty. Since I didn't drive enough, the seal issues on my car took longer to start leaking, and then out of warranty. HELP!

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.

I have had this happen several times on my 2021 Outback and my 2013 Outback. The dealership has never been able to recreate this issue. I will be driving (gear in D) and it randomly shifts to 1st or 2nd gear. I have been in a parking lot when it has happened or entering the interstate. I notice it because I hear the engine roar and look down to see it shifted gears. I only use D so this should never happen.

Should be a recall. Part was redesigned in 2022 I read.
