Subaru Forester power steering loss problems

Filed Nov 7, 2026 · WI

Approximately a half dozen times since I bought my 2018 Subaru Forester Premium new in December of 2017 it has exhibited unintended acceleration, usually after I start it or travelling slowly, as when doing parking maneuvers. When this happens the car will suddenly lurch forward and the engine will roar, even when my right foot is firmly on the brake and no foot on the gas pedal (I use my right foot only on the pedals). The only way I've found to stop this problem is to turn the car off. Upon restarting the car, it drives normally again until this problem reoccurs, which may be weeks or months later. I've examined the possible reasons that this is happening and have eliminated the possibility of the car mat or pressing the wrong pedal or both pedals at the same time. I've tried to press both pedals at the same time on purpose with the car off to check if this is possible, and am unable to press both pedals without my foot slipping between the pedals. I've also experienced the power steering warning light illuminate a few times upon starting the car, upon which the car has no power steering. Turning the car off and then back on again has solved that problem.

• Symptom: Total electrical and mechanical shutdown at highway speed (70 mph) immediately following the manual disengagement/deactivation of the cruise control system. • Behavior: Complete loss of engine power, power steering assist, braking assist, and all instrument cluster functionality. • Post-Incident Diagnostic: An OBD-II code reader scan registered zero active, pending, or historic DTCs, indicating an instantaneous loss of primary ECU/ECM power or a critical grounding drop rather than a sensor-driven component fault.

Component Failed & Inspection Availability: The vehicle suffered a sudden, catastrophic mechanical engine block failure at 74,000 miles. The dealership teardown confirmed a failed/spun lifter bearing and a fractured connecting rod cap, requiring a complete engine replacement. This sudden oil pressure failure/blockage occurred while the engine oil pan was verified completely full. This sudden mechanical failure is directly consistent with severe localized thermal breakdown from a failing Thermo Control Valve (TCV)—a component subject to Subaru Warranty Extension WMM23—or loose factory RTV silicone debris clogging the oil galleries. The failed components, including the engine block, rod cap, and TCV, have been retained by the owner and are fully available for inspection upon request. Safety Risk: The engine failed catastrophically and seized instantaneously while driving at highway speeds, causing a sudden and total loss of motive power. This created an immediate hazard as the vehicle rapidly decelerated in active traffic without warning, blinding drivers behind me and stripping the vehicle of power steering assist. This forced a dangerous maneuver to navigate the disabled vehicle through highway traffic to the shoulder, significantly risking a severe rear-end collision. Dealer Confirmation & Inspection Status: The problem and point of failure were officially confirmed and documented via a physical engine teardown conducted by a certified Subaru dealership service center. Subaru of America Corporate Advocacy was notified under Case Number 260818-1500487 but denied coverage. The components have not been inspected by the police or insurance representatives, but they remain preserved as physical evidence. Warning Lamps & Symptoms: There were no warning lamps, check engine lights, low-oil indicators, or abnormal electronic codes prior to the instantaneous mechanical failure. The vehicle had been professionally serviced and oil-changed just 3,800 miles prior to the breakdo

While driving in [XXX], the passenger-side front lower control arm on my 2007 Subaru Forester (VIN: [XXX]) fractured without warning due to severe internal rust corrosion. The structural collapse snapped the CV axle and sway bar link, causing an immediate loss of steering control that forced the vehicle to veer violently off the road—narrowly avoiding crossing the center median into oncoming traffic. Subaru service history confirms that Safety Recall WVX-34 (the federal safety agency Campaign 11V464000) was performed on this vehicle 14 years ago, where an anti-rust coating was applied instead of replacing the part. That factory recall remedy failed to prevent internal rust-through long-term, directly resulting in this crash and mechanical failure on a public road. Subaru of America Customer Advocacy has refused assistance, mischaracterizing an ineffective recall remedy as an expired standard warranty issue. The vehicle was towed to an independent repair shop where the failure and secondary damage were confirmed, and the fractured components are preserved for inspection.

My new vehicle, with under 4,000 miles, has already suffered multiple chewed wires due to rodents attracted to the soy-based wire coatings used by the manufacturer. This is not a minor inconvenience — it is a serious safety issue. Damaged wiring can cause loss of power steering mid-drive, ABS and braking system malfunctions, airbag deployment failures, engine stalling on highways, and electrical fires — any of which can result in injury or death. The manufacturer knows soy-based coatings attract rodents, the consequences are safety-critical, and proven mitigations exist (capsaicin-infused coatings, hardened sheathing, metal conduit) yet are not implemented from the factory. If vehicles are engineered to withstand foreseeable environmental hazards like water intrusion, heat, and road debris, there is no justification for leaving critical wiring defenseless against a well-documented and predictable threat. A material choice known to invite damage, paired with insufficient physical barriers, is not an external cause — it is a design flaw.

I am reporting a serious safety issue involving my 2019 Subaru Forester related to failure of the Electric Power Steering (EPS) system. Since April 21, 2026, I have been in communication with Subaru of America regarding whether this issue is related to an existing safety recall (WUC-88). During this time, I provided detailed information about multiple occurrences of EPS warning light activation and intermittent loss of steering assist while driving. A local repair shop also inspected the vehicle and confirmed EPS-related diagnostic trouble codes (including B2811 and C2512), which are consistent with known EPS issues. This information was shared with Subaru of America; however, I did not receive a clear or actionable response, and the case has been delayed without resolution. Initially, the issue was intermittent, with the EPS warning light turning on and off. However, since May 9, 2026, the EPS warning light has remained continuously ON, indicating that the condition has worsened. On May 11, 2026, I visited an authorized Subaru service center while the EPS warning light was actively ON. Despite the issue being clearly present, the dealership only took photos confirming the EPS warning light and did not perform any additional diagnostic testing or repair. They advised that the EPS rack needs replacement at an estimated cost of approximately $2,500, with the part currently on backorder and no clear repair timeline. I have already reported this visit and the current condition to Subaru of America and am still awaiting a response. This issue involves intermittent and now persistent loss of steering assist while driving, causing the steering wheel to become extremely stiff and difficult to control. This poses a significant safety risk. Given that the issue has been ongoing since April, has been confirmed by both a repair shop and a Subaru dealer, and remains unresolved, I believe this represents a safety defect that is not being properly addressed.

When parked on a slope, driver attempted to back SUV out of parking space. Before starting car, with key inserted, ignition on and foot on brake, driver attempted to remove gearshift from park. Car drifted backward rapidly and uncontrollably. The brakes completely failed even with foot on brake. The car was a hazard to anyone in its path and could not be stopped. The emergency brake was attempted but failed to stop the car. Power steering failed. Gearshift could not be put back into park. SUV crashed heavily into a sign protecting the gas pump, but auto suffered major damage: REAR WRAP AROUND BUMPER, ENTIRE POWER LIFT DOOR, AND FRAME, were included in the damage. Driver was the wife of a couple. Very importantly, the husband had experienced the exact same uncontrollable roll-back in the same vehicle at the same place a few weeks earlier, but somehow missed the gas pump and sign. At that time, the car was uncontrollable and caused panic for both drivers in separate incidents. THAT'S NOT ALL--of key importance was a conversation we--as a couple--had with the salesman and the dealership's lead mechanic when the auto was purchased in 2017. We pointed out that when backing out of a space on a slight downslope and changing gears, the car drifted backwards uncontrollably a number of feet--at least three to six feet. At that time in 2027, we told them we did not like this feature, and it could be a danger to children playing in the driveway. They said that the manufacturers' engineering department knew about this. And were making improvements. Subsequently we investigated this engineering/design fault online, discussed it again with the dealership, then dropped the issue. THE BOTTOM LINE: THIS SEEMS TO US TO BE A GENUINE MANUFACTURING FAULT. WE BOTH EXPERIENCED THIS UNCONTROLLABLE DRIFT BACK WHEN ATTEMPTING TO BRAKE THE CAR. IT IS FRIGHTENENING AND DANGEROUS TO BE IN A VEHICLE WEIGHING TONS WITHOUT ANY ABILITY TO CONTROL IT. PLEASE INVESTIGATE.
