Subaru Impreza transmission 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 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)

Transmission failure while at high speed on an interstate highway resulted in disengagement, immediate deceleration and limited steerage in an area with limited breakdown lane. Subaru reports this is a known issue for which they extended warranty but it is incomplete and does not include any safety check prior to failure!

The vehicle was at a stoplight. Once the light turned green, the driver stepped on the gas. All of a sudden the car would not move, all the warning lights came on, and we could smell a burning smell. The car was towed to the dealership where it was purchased. They discovered a rubber hose leading to the transmission had somehow gotten cut and all the transmission fluid leaked out. This caused a total transmission failure according to the dealer. It must have happened almost instantaneously as there was no warning prior to this. This hose is clearly critical to the operation of the vehicle and safety of the occupants, yet is totally exposed to the underside of the car. If the failure occurred while the vehicle was moving, it could have been a serious safety issue. It seems like a simple steel braided hose or a metal tube should have been used on such a critical part.

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.
