2020 Subaru Crosstrek Complaints

DEFECT DESCRIPTION My 2020 Subaru Crosstrek has been diagnosed with diagnostic trouble code P2757 (Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance), which my authorized Subaru 802 Subaru retailer in Vermont has confirmed is caused by a defective CVT Control Valve Body. Subaru of America has acknowledged this exact defect in Technical Service Bulletin 16-156-25R (revised 10/28/25), which explicitly covers the 2013–2021MY Crosstrek 2.0L (FB20 engine, TR580 CVT) and prescribes replacement of the CVT Control Valve Body with an updated design incorporating an improved valve sleeve. This bulletin confirms that Subaru is aware of the design flaw in the original valve body and has developed a permanent engineering fix. WARRANTY EXTENSION DISPARITY Subaru of America issued a CVT Warranty Extension on June 30, 2025 (Retailer Bulletin 16-155-25R, revised 07/14/25) extending CVT coverage from the original 5 years/60,000 miles to 10 years/100,000 miles for certain 20...

My 2020 Subaru Crosstrek CVT Valve Body equipment failure and CVT Torque Converter failure. This appears to be a common failure for prior Subaru Crosstrek model - however was not extended for coverage to 2020 and beyond models - appears the issue still persists and additional year models should be covered. My vehicle experience the same failure for CVT Valve Body failure and CVT Torque Converter while driving at highway speeds. Problem occurs for previous Subaru Models example: MC-11021247-0001, Subaru Service Bulletin: 16-155-25R where Subaru extended coverage to 10yrs/100k miles or +1 year from date of notification - and my vehicle is currently at the Subaru Dealership for repairs for both CVT Valve Body and Torque Converter. Warning lights did not appear until issue occored.

While driving 2020 Crosstrek Hybrid, the dashboard lights suddenly flashed and then engine stalled, leaving me with no brakes and no steering. I rolled through straight through an intersection with four stop signs and I could not stop. Luckily no one was driving or walking at the time. I couldn't start car, even with a jump start. I bought a new Interstate battery with higher specs. Three days later the same thing happened, the car stalled while driving just about to park. The dashboard lights also flashed and I saw Hybrid System this time. Car was towed to the dealer and there was a huge amount of corrosion with the electrical system underneath the car. Previously, four times this winter the car batter was completely dead after being parked in a garage and twice in a parking lot. I was told by a mechanic who gave me a jump start that there's a parasitic drain somewhere.

My 2020 Subaru Crosstrek experienced a sudden loss of motive power and stalled due to a blown ignition fuse. Diagnostic code P1604 (Startability Malfunction) was stored. Inspection by Wayne Subaru (Invoice #25340) confirmed the Cylinder 3 ignition coil had shorted and physically melted. This is the exact failure mode described in Subaru Safety Recall WRE-21 (NHTSA Campaign 21V825000), which currently only covers 2018–2019 models. My vehicle experienced a thermal event and a stall despite being a 2020 model. The dealer replaced only the melted coil and did NOT update the ECM software. This leaves the vehicle at risk of a repeat stall in traffic, as the underlying software defect that causes coils to overheat remains unaddressed in the 2020 model year and the remaining coils may already be at risk.

Beginning one year after buying this used 2020 Subaru Crosstrek base trim the starter failed and battery fully died after failing to start from a stop. The engine was OFF due to the auto-stop system and failed upon lifting my foot from the brake on a slight incline, causing a constant warning beep and a starter system failure message on the dash display. Immediately after failing to start the brake pressure significantly dropped causing my car to roll into the front of the car behind it. The car was stranded in the road and required a jump start. Since this event the issue has occurred twice more on two brand new batteries on no incline, and I now fully disable the auto-stop feature before driving to avoid an accident. The car starts properly with no battery damage if started from the full ignition off position, even if auto-stop originally stopped the engine, pointing to a failure of the auto-stop system specifically. Importantly, I have also personally seen this exact failure occur t...
