Subaru Crosstrek cvt failure problems

Filed Nov 7, 2026 · Electrical, Fuel system · PA

While driving, the car stalls out. Sometimes it recovers automatically, but most times I need to restart it, causing me to be very concerned about a possible rear-end crash. I have taken it to the dealer (Rafferty in Newtown Sq PA) twice. The fist time (Oct 8th) the MAF sensor was replaced and a fuel induction service was performed. The problem seemed to be fixed for about a month and it recurred. The second visit (Nov 6th), the technician wanted to perform a fuel induction again until I reminded him he had already done that. He did replace a clamp on the loose intake hose. Upon return, I looked up the problem online and found some possible solutions that weren't offered, like: 1. Ignition coil ECM short circuit 2. CVT Torque converter lockup solenoid 3. Crankshaft position sensor (perhaps that is the MAF sensor that was replaced) I have opened a case with Subaru (Case #261107-1500076) and am waiting to be contacted by a Field Tech Specialist.

2023 Subaru Crosstrek, 88,000 miles. Oil temperature warning light illuminated on October 5, 2026; dealer diagnosed CVT torque converter failure requiring replacement ($2,954 repair). This is the second CVT failure in two months: the same dealer replaced the CVT valve body in August 2026 (~$3,400) for the same warning light. Vehicle has remained parked at the dealer since the failure — driving with a failing torque converter can damage the CVT. Submitting as a transmission defect report."

While driving, my dashboard warning lights on my 2019 Subaru Crosstrek—AT OIL TEMP, EyeSight, and Lane Assist—illuminated simultaneously with a sudden onset of transmission slippage and erratic shifting, with no prior warning symptoms. The vehicle experienced a sudden mechanical failure of the Continuously Variable Transmission (CVT) torque converter clutch solenoid valve, which was diagnosed and confirmed by an independent service center under diagnostic trouble codes P0971 and C1431. This sudden loss of reliable vehicle propulsion and disabling of active driver-assist safety systems created an immediate collision hazard, severely compromising driver control and vehicle safety in live traffic. Subaru is denying reimbursement for this known CVT defect, expecting consumers to foot the bill after relying on a single mail notification sent 13 months prior. Although the failed component was replaced during this emergency repair using genuine OEM parts supplied directly by an authorized Subaru dealership parts department, all diagnostic logs, itemized parts records, and repair documentation are attached.

I am reporting a possible power train/drivetrain issue with a 2025 Subaru Crosstrek Wilderness. At steady highway speeds, most noticeably around 72–76 mph under light accelerator load, the vehicle produces a persistent high-frequency ringing/whining tone throughout the cabin. The noise stops when I lift off the accelerator and rarely occurs when traveling downhill, which suggests it may be related to drivetrain load rather than ordinary wind, road, or tire noise. The suspected component or system is UNKNOWN, but based on the operating conditions it may involve the CVT, differential, or related drivetrain/power train components. The vehicle is available for inspection upon request. The issue has been reproduced and confirmed by a Subaru dealer. The vehicle was previously inspected by the dealer, and the rear differential was replaced during an attempted repair, but the noise persisted. The vehicle was returned for additional diagnosis, and dealership personnel confirmed the same noise. The manufacturer later stated that the condition was considered a normal characteristic after comparison with another like-model Crosstrek Wilderness, but no specific root cause or technical explanation was provided. My safety concern is that a persistent, load-dependent drivetrain noise at highway speeds could indicate abnormal wear, resonance, or mechanical instability in the CVT, differential, or related power train components. If the condition reflects an unresolved defect, it could potentially lead to premature drivetrain failure or loss of power while driving at highway speeds. There have been no warning lamps or dashboard messages associated with the condition. The issue first appeared while the vehicle was still very new and under factory warranty, and it remains unresolved.

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 2019–2020MY vehicles. However, the 2020 Crosstrek equipped with the FB20 engine and TR580 CVT was specifically excluded from this extension, despite: 1. The 2019 Crosstrek (identical FB20/TR580 drivetrain) being included in the extension. 2. The 2020 Impreza (identical FB20/TR580 drivetrain) being included in the extension. 3. TSB 16-156-25R explicitly listing the 2020 Crosstrek as an affected vehicle with the same valve body defect. This exclusion appears arbitrary and inconsistent. Owners of the 2020 Crosstrek are being denied warranty coverage for a documented design defect that Subaru has acknowledged and corrected through a TSB, and for which owners of vehicles with the identical powertrain (same engine, same CVT) are receiving extended warranty protection. SAFETY CONCERN DTC P2757 indicates a failure in the torque converter clutch pressure control circuit. This defect can result in unexpected transmission behavior including hesitation, shuddering, loss of power delivery

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.

The car started shaking and shuddering at 40 mph on a straight road and I had several losses of motive power, with sluggish acceleration of a busy road. All dashboard lights began to turn on. The Oil Temp light was flashing, indicating an powertrain issue. After slowly driving it to a Subaru dealership, I was told that the CVT needed to be replaced. This model year also had a loss of motive power when cylinder 4 short circuited (after full replacement due to a recall). These are two examples of loss of motive power at high speeds on a single vehicle which in my opinion constitute a severe safety issue

PCV problems and the dealership saying they fixed and completed this recall and have not done so and now CVT problems saying there’s no parts to fix it and have to re do the whole valve system Starter with thinking it was a wheel bar ring problem To trying to figure out if it was a pcv with the engine or cvt with the transmission These are major safety problem that should not be happening

I am writing to formally raise a significant safety concern regarding my 2018 Subaru Crosstrek. I recently discovered a malfunction in the transfer case (pictures attached), specifically involving the center differential gear set, which necessitated immediate replacement. This issue first became apparent while driving at low speeds when I heard a loud, distinctive "clunking" noise, indicating a possible malfunction within the transmission. As a precaution, I took the vehicle to my service mechanic for further diagnosis. After thorough inspection, my mechanic at Roberts Auto Shop (invoice attached) promptly identified the transfer case as the source of the problem. Subsequently, I contacted my local Subaru dealership, North Tampa, where I have previously serviced my vehicle, to inquire whether this issue is known to affect earlier models of the Crosstrek. The service manager expressed surprise that this problem occurred in my manual transmission vehicle, noting that it is typically documented in vehicles with CVT transmissions but rarely in manual models. I further inquired about the availability of any extended warranties or safety recalls related to this known issue. The manager informed me that the vehicle's powertrain warranty covers only up to 60,000 miles or five years, both of which I have exceeded, as my vehicle currently has just over 70,000 miles. My primary safety concern arises from the discovery of metal shavings inside the defective transfer case during its replacement. While the amount is currently minimal, there is a significant risk that this could quickly escalate into a complete transmission failure, posing a considerable safety hazard. I am planning to report this issue to Subaru of America for further investigation and would appreciate your assistance in investigating this matter. I also request that Subaru be held accountable for this known defect, particularly given its potential to jeopardize vehicle safety. Thank you for your support.
