Subaru Impreza cvt failure problems

Filed Oct 23, 2026 · Transmission · IL

COMPONENT & AVAILABILITY: The Lineartronic Continuously Variable Transmission (CVT) system suffered internal mechanical/hydraulic failure (TR580 unit). The vehicle and transmission assembly remain intact and available for immediate inspection upon request. SAFETY RISK: The transmission experienced erratic downshifting, slipping, and failure of proper engagement, creating an imminent risk of sudden deceleration, complete loss of motive power, and stalling in traffic. After diagnostic codes were cleared during an independent reassembly, Subaru of America and its dealer (Berman Subaru of Chicago) refused to inspect or repair the defect, directing that the vehicle be driven until it re-fails and sets a light. Operating a vehicle with documented internal transmission failure until it stalls at highway speeds creates an severe hazard of rear-end collisions. CONFIRMATION: The failure was confirmed on May 26, 2026, at 97,786 miles by licensed specialist A Plus Transmission Specialists Bellaire (Houston, TX; RO #27012). Technicians verified downshift faults on road testing, performed electronic scans, dropped the pan, and disassembled components, documenting internal failure via logs and photos. PRIOR INSPECTIONS: Presented to dealer Berman Subaru of Chicago and Subaru of America Customer Advocacy; both refused to evaluate the physical transmission or teardown findings because the dash light was not currently lit. No police or insurance inspections. SYMPTOMS & TIMELINE: In May 2026, Check Engine and warning lights appeared alongside downshift malfunctions. Diagnostic scans captured TCM communication and powertrain faults (including C1431). Codes were cleared by the specialist during component reassembly and bench testing.

I am filing a complaint regarding a known issue with the CVT transmission in my 2014 Subaru Impreza, currently at approximately 80,000 miles. The CVT has started making a loud whining noise while driving. A licensed, independent repair shop diagnosed this as a likely early sign of internal CVT failure, advising that failure is imminent without repair or replacement. After researching the issue, I discovered that Subaru issued an extended warranty (WQA-86) specifically covering this known CVT defect. However, I was never notified of this extension or any service campaign. I learned about it only after experiencing symptoms and conducting my own research. By that time, the extended warranty had expired in February 2024 , only a few months before I began experiencing problems, despite my vehicle being well under the mileage limit for coverage. I maintain a service history with full documentation from licensed repair facilities. I submitted a goodwill assistance request to Subaru to cover the inspection and repair or replacement of the CVT based on this known defect and the professional assessment from my mechanic. Subaru denied the request solely because the extended warranty had expired by time, despite the fact that: I was never notified of the warranty extension or technical service bulletin (TSB). The issue is well documented and acknowledged by Subaru. My vehicle is still under the mileage limit. A qualified mechanic has confirmed early signs of failure. This is a serious safety concern, as CVT failure can lead to sudden loss of power or acceleration while driving. Subaru should be held accountable for notifying all affected owners about extended coverage related to known defects. I am requesting that Subaru be required to provide goodwill coverage or cost assistance for this repair, as the failure is directly related to a known manufacturer defect and the lack of notification prevented me from taking timely action.

Last month, my 2013 Subaru Impreza Sport with only 67k that I bought brand new had a blinking AT (Automatic Transmission) Oil Temp light and three other lights were lit on the panel. I contacted Groove Subaru and they told me that I had a malfunctioning Valve Body and needs to be replaced. I was told that this is a common issue with Subarus with CVT transmission reason why they changed their warranty to 10years/100k miles. Mine has only 67k miles and already malfunctioned. They said they won't cover mine because I'm on the 11th year so they asked me to pay $2500 for everything. Reason why I'm writing this letter is to inform you that this should be considered as recall and I shouldn't paid for anything. My car is good as brand new. I seldom use it. Please help me consider this as recall since it is happening on all Subarus with CVT transmission. Thank you!

I was on the highway in mixed traffic for a couple hours. There was a burning smell in the cabin and then the warning lights came on including a check engine light and transmission light. The car started to jerk erratically when I accelerated and ultimately it would not accelerate. I pulled over and turned the car off as recommended in the owner's manualAfter following the manual's instructions to let the engine cool down, I attempted to turn the car on and put it in gear. It would not move when I put it in reverse or drive. The transmission failed entirely. Previous to my taking the car on this trip, I brought the car to my Subaru Dealership because I smelled the same burning in the cabin along with a strange whirring sound and the transmission light came on then too. At that time, I pulled over and read the owner's manual and did what it recommended. The car started working again after 10 minutes of cooling. This is why I brought the car to the Subaru dealership to have this issue inspected. At the time they recommended that I change the CVT fluid and that the issue would then go away. The issue did not go away. When I informed them that the car was unsafe and dangerous to drive because of the jerking and violent shuddering, they told me that I should trade the car in or pay for a new transmission. They did not tell me that the 2012 version of the car had a history of issues with its CVT, and that some of the repairs were covered under warranty.

To whom this may concern, My name is [XXX] . I purchased my 2014 Subaru on December 13th, 2013. My car has 57,000 miles on it. It has loss of acceleration when entering a freeway. I push on the gas pedal harder and harder to try to get my car to obtain 60 mph. The car does not respond until minutes go by. The CVT transmission was replaced in June 2022. The car has not performed any better after the transmission replacement. I am the original owner of my car. Initially, my car performed very well, quick response to acceleration for the first 35-40 thousand miles. Then, it began to have lack of acceleration. The transmission was replaced by Subaru of America in June 2022 at around 48,000 miles. I brought my car to Elk Grove Subaru approximately 4 times since the transmission was replaced, each time I paid for their hourly diagnostic fee; between $165.00 to $195.00. Each time the service advisor said they found nothing wrong with my car. I took my car to two independent mechanics (One of them is a transmission repair shop) they each stated in writing that my transmission is slipping and has loss of power. I feel unsafe driving my car on the street as if shakes, shudders and jerks. I do not want to be a statistic in an accident on the freeway due to the lack of power trying to obtain speed while entering freeway and trying to keep my vehicle speed at a speed of barely 60 mph. My vehicle is still within the extended CVT warranty. I feel that the Subaru dealership is purposely avoiding acknowledgement of the failing transmission. Subaru is a big corporation. Many Subaru owners believe there needs to be an actual recall on their Subaru CVT transmissions. I do not feel safe driving my car. With 57,000 miles on a vehicle that's a potential safety hazard, Subaru needs to take more responsibility for their vehicles as people's lives are much more precious than their profit margins. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The transmission on my 2014 Subaru Impreza failed suddenly while I was driving about 70 mph in the middle lane of the interstate. My car began to decelerate rapidly, and I lost all ability to accelerate or even put my car in park. I was able to navigate to the side of the interstate and use the car's emergency brake to come to a stop. The event was extremely traumatic, and I have nightmares about losing control of my vehicle on that interstate with cars whizzing past me. I was stranded in a very remote area, barely making it onto the shoulder of the interstate, over an hour from my home and in a different state. During the three hours I waited for a tow on the side of I-5N, I discovered the many the federal safety agency bulletins issued regarding CVT transmission issues with the 2014 Impreza and the consequent extended warranty. Thus, I paid out of pocket to have my 2014 Impreza towed the thirty miles to the closest Subaru dealership, expecting the repair to be covered by the warranty. My car’s mileage is 71,612, and it is under 10 years old, falling within both requirements of the extended warranty. There had never been any indication of transmission trouble, and Subaru never contacted me to inform me of the known CVT transmission issues. No warning lamps, messages, or other symptoms ever appeared regarding the transmission. After inspecting my vehicle, the Subaru dealership verified a transmission issue, and claimed that the car was roughly 3 quarts low on CVT fluid. Despite the federal safety agency safety bulletins about known transmission fluid seepage issues in the 2014 Impreza, Subaru is trying to skirt responsibility for the known defect, and instead, they are claiming that it is the fault of a reputable independent mechanic stating that they *suspect* that since it was 3 quarts low because the independent shop did something wrong. However, records show otherwise. Subaru is not standing by its extended warranty and attempting to shirk responsibility for known CVT defects. Permission to inspect.

My check engine light and other lights simultaneously lit up while driving 50 mph down the highway. The car started to “buck” slightly. I pulled over, let it cool a bit, checked the oil. Oil level and quality was fine. Took to a mechanic where I found the problem was with the CVT. This car has only 100,283 miles on it! It should not be having transmission problems. This is a defective system. Repairs are more than the car is worth. (Even though I’ve kept it in good shape).

My transmission completely locked up on me while driving at interstate speeds. I was traveling at 65 MPH with the car in regular driving mode, on cruise control and the transmission completely locked up on me. The front tires locked briefly, causing me to go into a small skid, which I was able to correct, and then the engine revved high and I had no power. This lockup and skid caused a rapid deceleration of the vehicle and had there been lots of traffic around me it would have caused a major accident on the interstate, possibly causing fatalities. My transmission completely locked up once I went through the nearest intersection to get to a side road. This left me stranded in the middle of a major highway intersection with no ability to physically push my vehicle out of the way. The vehicle behind me just about rear-ended me. This has been a major issue with these transmissions and a major safety issue. These transmissions should be put on a recall since this is a major safety issue. The extended warranty that Subaru has put out only waits for a problem to occur, this does not save lives but only puts them in danger. They should be FORCED to do a recall. No warning lights illuminated on the dash prior to the transmission locking up. The vehicle has been inspected by a certified mechanic and has diagnosed that it is an issue with the transmission itself and no other component on the vehicle. This issue of the CVT transmission is well documented.

Was driving on I-70 in Colorado going 60-65 mph uphill when all indicator lights came on and AT (Automatic Transition) Oil Temp light began flashing. Check Engine, Hill Assist, ABS, and Traction Control lights all came on steady on. Had to pull over and had significant power loss during driving. Googled what AT Oil Temp light meant and called a tow truck to take to my mechanic. Mechanic initially indicated it could be valve body problem which in his words is a "known issue with Subaru CVT engines." Code pulled was p2764. They ended up pulling the pan and draining fluid and found excessive metal built up on magnet in pan. This pan and headgasket were repaired less than 6k miles ago (October 2020) and at that time they said everything was in good shape so something drastic happened to CVT in less than a year. Mechanic unable to say what caused the excessive buildup in that time. Safety compromised as left on side of very busy highway waiting for tow - we were also concerned with whether or not car would overheat/catch on fire due to AT oil being over 200 degrees. Problem confirmed by our mechanic and indicated that we need a full transmission replacement. No other warnings prior to this event. Maintenance is current and in 2018 performed recall service indicated by Subaru for valve spring issue.
