Subaru Outback loss of power problems

Filed Sep 30, 2026 · Engine · AZ

Catastrophic motor failure at highway speed. I had just come of the Interstate 10 and stopped at the end of the off ramp. I made a right turn on to a 2 lane county highway and accelerated back up to 65MPH. As I attained speed, the vehicle lost power. The accelerator pedal was dead and the vehicle did not respond to my input. The oil pressure warning light illuminated, power surged back and was immediately lost again with dead pedal again. The vehicle would not respond to my input to accelerate and effected my ability to control it safely. I had to abruptly pull to the should and coast to a stop. Loud engine knock immediately occurred indicating catastrophic motor failure. The vehicle was immobilized and needed to be towed. I was fortunate the instant motor failure did not occur while attempting to pass another vehicle or any other maneuvers where I needed the vehicle to respond and move out of the way instantly.

9/20/26 my 2020 Subaru Outback experienced repeated electrical failures followed by loss of power-steering assistance. The underlying failed component is unknown. The vehicle is parked and available for inspection. While driving, the vehicle intermittently lurched/jerked as the center display went completely black and restarted and EyeSight repeatedly became unavailable and returned. After stopping for fuel, I attempted to restart the vehicle. It initially started and then became completely electrically unresponsive: no response from the push-button start and no accessory power. Electrical power unexpectedly returned after I opened the driver's door, and I was able to restart the vehicle. Later, while the engine was continuously running in a parking lot, the display repeatedly blacked out and restarted while EyeSight repeatedly became unavailable and returned. When I shifted into reverse, the vehicle began jerking and power-steering assistance failed. The steering wheel became extremely difficult to turn and jerked in my hands, preventing me from properly completing the reverse maneuver. I shut the vehicle off and restarted it, which temporarily restored steering. This unpredictable steering failure put me, my two children, and other road users at serious risk. After restarting, I had to travel 65 mph on a highway to get home. Had steering assistance failed again at highway speed, I could have lost lane control or been unable to avoid other vehicles or road users, potentially causing a serious or fatal crash. The vehicle has not yet been inspected for this incident. The repair facility has been notified and I intend to have it towed because I consider it unsafe to drive. Six weeks earlier, the facility inspected the battery, terminals and cables and marked them satisfactory. Prior warnings included EyeSight becoming unavailable, the display blacking out/restarting, and vehicle lurching. I observed no separate steering warning before steering assistance failed.

The CVT transmission in my 2013 Subaru Outback failed at approximately 93,000 miles. Approximately three weeks prior to the failure, I noticed an unusual sound while driving, but no other symptoms were apparent at that time, so I continued monitoring it. On the day of the failure, the rear tires began hopping and I lost acceleration while driving. Fortunately, this occurred while I was on my driveway, so I did not need to continue driving further. I parked the vehicle there and had it towed to my mechanic, and later to Rairdon Subaru of Auburn (WA), where the failure was diagnosed by their service department. The vehicle is available for inspection there. This loss of power and erratic rear-end behavior created a safety risk, as the same failure occurring while driving on a road could have affected the vehicle's ability to accelerate and respond predictably in traffic. This is a known issue: Subaru's own Technical Service Bulletin 16-107-17R acknowledges CVT transmission problems in 2010–2015 model year Outbacks and other models, and extended the powertrain warranty coverage for this issue to 10 years or 100,000 miles. My vehicle has only about 93,000 miles, but Subaru is denying full warranty coverage because the vehicle is outside the 10-year time limit, despite being well under the mileage limit. The vehicle has not been inspected by police or insurance representatives — this was a mechanical failure, not a collision.

The car started to make very loud engine noises and then the engine completely failed. The car was no longer able to accelerate and lost the ability to go in both forward and reverse. Luckily, my son had just arrived home when the car completely lost power, but it began to have acceleration issues as he was driving home. No warning lights came on until after the car had completely failed. Less than a week prior to the incident, the car had an oil change and inspection by the dealership and no issues of concern were noted. The car was towed to the dealer. The technician said that the oil contained metal shavings, indicated an engine block failure.

the federal safety agency issued a notice for a recall on the 2015 Subaru Outback for an exhaust pipe bellows crack which causes exhaust noise and odor which affects emission and engine performance. I had noticed our Subaru's exhaust smoke coming in through the air vents while idling and also a general loss of power for the vehicle. When I dug into the causes, I came across this recall and did the VIN look up on the federal safety agency website and also the Subaru website for active recalls. The Subaru website states that the recall was completed. I then called the subaru retailer to check if there were any records for the recall work that was completed for the federal safety agency ID Number: 10199936. They could not find any records. I called in Subaru corporate to see if they could shed any light on the recall. Subaru corporate says that the recall work was performed on August 6th, 2020 but is unable to tell me where it was performed or even if it was actually replaced. My local Subaru dealer has no records and Subaru corporate says that the work was performed. I am stuck with an exhaust leak that is potentially dangerous as time goes on where it might fail emissions. Subaru corporate has not wanted to address this or investigate the discrepancy, but instead asks me to work with the dealer to get records. The dealer says there's no records of the work ever being done. So I'm in limbo with a particularly faulty car.

On Monday [XXX] were driving on [XXX] going north up [XXX]. I was doing about 60-65 mph in traffic which was flowing in both directions. While ascending the pass, the car suddenly started to misfire, rapidly lost power, power steering failed and all dash lights lit up. With no shoulder to pull out this was a very scary experience. Eventually managed to limp to a spot where I could pull out off the pavement. Car was dead. Popping the hood showed significant battery corrosion. I had a toolkit with me. The voltmeter measured the battery voltage at 9.3V. Thinking maybe cleaning the battery terminals would allow the car to be restarted, I managed to get the cables off and cleaned everything with a wire brush. But still no power. After a while a state trooper passed by and hung on while I contacted a towing service. After another 1.5 hours, the tow truck arrived and towed the car the 60 miles or so to the dealership in Denver with my wife and I in the cab of the tow truck. Dealer repair invoice indicated Data Control Module (DCM) "causing excessive draw on electrical system." More significantly, the battery had drained below the the operating threshold voltage required for vehicle drivability (understood to be 10-10.5V). There was no mention of this by the dealer service adviser. Although dealer diagnostic was carried out, no computer codes were provided. Vehicle mileage at time of incident 73,456. I have owned the car since new and have all service records. Car was repaired and picked up from dealership on 06/10/26 with a replacement DCM. Battery was charged up but not replaced and left in corroded state. Battery will probably have been weakened by such a total discharge with reduced life expectancy. I have uploaded the dealer repair invoice. I have reported this incident to Subaru of America. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On June 15th 2026, I was at a red light and the Auto Start-Stop feature shut off the engine. When light turned green, my car lost power and started rolling downhill. During this rolling downhill, the brakes stopped working, I was unable to engage parking brake, and I wasn't able to do anything except find a place to safely use gravity to slow the vehicle down. If the hill was steeper, this scenario could have been deadly. It was so scary, I called 911 for assistance but got lucky I was able to stop the car before there was an accident. It turns out the battery didn't have enough power to allow the vehicle to restart and if this happens when the Auto Start-Stop feature is engage you lose the ability to use the brakes. I spoke to the local dealership and acknowledge that is a problem.

While driving the 2016 Subaru Outback, the vehicle experienced a sudden, catastrophic failure of the Continuously Variable Transmission (CVT). The transmission completely failed, resulting in an immediate and dangerous loss of propulsion while operating the vehicle. This created an immediate safety hazard for myself, my toddler and other drivers on the road, as the vehicle could no longer maintain speed or accelerate safely to clear traffic. A certified repair facility diagnosed the issue as a complete internal mechanical failure of the transmission, requiring a total replacement at an estimated cost of roughly $11,000. This generation of Subaru CVTs has a well-documented history of premature, catastrophic mechanical failure, which Subaru of America has previously acknowledged via past warranty extensions. The sudden loss of power caused by this engineering defect poses a severe and ongoing safety risk to consumers.

I was reversing out of a residential driveway onto a county highway when the I had a complete loss of movement. Shortly after the total loss of power, the CEL illuminated. If I had been on the highway, the driveway is near a blind curve, I would've been sitting in the road with no way to move putting me in a dangerous situation. The transmission failed at right at the end of the driveway so I was able to put it in neutral and move the vehicle by hand. There were no symptoms or warning lights prior to the failure. I had it towed to the nearest dealership where they diagnosed a complete transmission failure and recommend a complete transmission replacement.
