Subaru Impreza stalling 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 took my car to McCurley Subaru on Wed, [XXX] to have recalls repaired. They were unable to repair the recall due to rusted out brackets and bolts. McCurley contacted Subaru of America and opened a case trying to seek an alternate remedy to this issue. Subaru refused to offer alternate solutions so I am stuck driving an unsafe vehicle with a Federal Mandated recall that cannot be repaired. On my way home after picking up the car, it stalled out on a major highway, blocking traffic and causing unsafe conditions for myself, my 7 yo daughter and other people on the road. The check engine light is on continuously and the car runs so roughly that I am afraid to drive it any longer. Subaru of America opened Case Number: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Subaru stutters stalls, torque converter malfunction

Filed Mar 4, 2026 · Transmission · TX

I own a 2024 Subaru Impreza (base trim, FB24 engine). The engine has developed repeated oil leaks into the spark plug wells due to failed spark plug tube seals / valve cover sealing on the same engine. The first occurrence was around 24,000 miles. The dealer found engine oil in the spark plug tubes, diagnosed leaking spark plug tube seals (and/or valve cover gasket), and performed repairs under warranty. At that time, the car was relatively new and maintained on schedule. The second occurrence happened again around 30,000 miles. The dealer again found oil in the spark plug tubes, indicating repeat failure of the same type of seals on this low‑mileage engine. This has already happened twice within approximately 6,000 miles on a 2024 vehicle. Oil in the spark plug tubes can cause misfires, rough running, and potential damage to ignition coils and the catalytic converter. It also raises concerns about stalling or loss of power if the misfires worsen while driving. I am concerned that this may be a systemic defect in the FB‑series engines used in late‑model Subaru vehicles, not normal wear. I am requesting that the federal safety agency track this issue as a potential safety‑related defect involving engine sealing components (spark plug tube seals / valve cover gaskets) that allow engine oil to leak into the spark plug wells on 2024 Subaru Impreza models at low mileage.

The contact owns a 2017 Subaru Impreza. The contact stated while driving 15 MPH, the vehicle began to hesitate without warning. The contact then stated that while at a stop light, the vehicle stalled upon the depression of the accelerator pedal with the traction control symbol flashing on the instrument panel. The vehicle failed to restart after several attempts. An attempt to jumpstart the vehicle also failed to start the vehicle. The vehicle was then towed to the dealer where it was initially diagnosed with defective spark plugs and contaminated fuel. The contact was later informed that the failure was caused by a defective fuel pump that needed to be replaced. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 68,500.

This is the third time that this has happened on the highway. I was driving about 70 miles per hour when my acceleration cut out. My dashboard lights, head lights, and other electronics were still on, but the car stalled and would not accelerate. The car struggled to move forward, jerking while slowing down, and came to a stop. I was in the middle lane of traffic on the highway late at night driving home and wasn't able to get my vehicle fully out of the highway when it was coming to a stop. This put me in a very dangerous situation on the highway where my car could potentially be hit by people rushing by. I got out of the car and called 911, who helped me move my car to a safer location. Once the car stopped, i tried turning the key a few times and the spark plug ran, but the car would not turn on. The next day, the car did turn on and there were no warning lights or any other diagnostic readings. The car was taken to Subaru where they did diagnostic tests, but were not able to find any irregularities. I've had the same thing happen twice before and they couldn't diagnose the problem then either. I also experienced hesitation when accelerating where the car wouldn't accelerate, and then it would jerk forward when it did. After repeatedly going back to Subaru for this issue as the transmission is under warranty, they replaced the torque converter and said the problem was solved. I still experienced the hesitation and jerking while driving so I took it back, to which they said that it was driving normal, and that the hesitation was because of the way I drove the car. The car is not driving normal or safe because it stalled and stopped accelerating on the highway, like I told them it would again, putting me in danger. I believe it is the transmission that is damaged, and despite the extended warranty, they won't or can't address it. It would be available for inspection if it would help. There should really be a recall because they fight extended warranty claims

While driving on the highway in Denver, the engine stalled - I later learned that a valve spring broke and went through the engine, destroying it. I lost all power - lost braking - but was able to steer the vehicle off to the side of the road. I subsequently learned that about 160,000 Subarus - the same vehicle year, the same model car, the same exact engine - have been recalled by Subaru. However, this car, which suffered the same exact problem was considering "outside the window" of the recall. If I had been on the freeway at a normal rate of speed this could have been a very dangerous accident. My concern is hundreds if not thousands of these cars are still on the road and Subaru is well aware of the problem.

HEADLIGHTS DO NOT ILLUMINATE THE ROADWAY WITH ENOUGH LIGHT. This recall was entered on Aug 12, 2022 when do they have to fix it? What is a "timely manner?" How long are they allowed to wait. I called Subaru and they indicate they have no definitive time that they have to fix it? Why do they have unlimited time to fix a safety issue? It's been 10 months and you would think they would have the parts by now or are they stalling so that they will have a reduced number of cars to fix? I think the government should step up their enforcement on this issue and get Subaru to provide a timeline for the fix and not just "when we get to it" response.
