Electrical system
392 reports5 crashes1 fire
“On Sunday, [XXX], I was driving my 2017 Subaru Outback 3.6R Touring after leaving the [XXX]. After I had merged onto [XXX] and immediately before the first roundabout under [XXX], the vehicle emitted three warning beeps, numerous dashboard warning lights illuminated, and the engine began running roughly. I was traveling approximately 31 mph when the warnings began. While attempting to reach a safe place to stop, I entered the roundabout beneath [XXX]. At approximately 7 mph, the electronic power-steering assistance stopped functioning, making the vehicle extremely difficult to steer. I was able to exit the roundabout and pull into a parking lot without a collision. I turned the vehicle off, waited approximately five minutes, and restarted it. The warning lights were no longer illuminated. Diagnostic information later reviewed by Grand Junction Subaru documented that the vehicle’s electrical voltage had dropped to 8.6 volts during the incident. The dealership could not reproduce the event or conclusively identify its cause. Although the original alternator reportedly tested normal, the dealership reprogrammed the ECU/ECM, disabled the DCM, and replaced the…”

“My Outback has been through 5 genuine Subaru windshields this year, and 7 since 2019. Only one was impact damage, the rest developed cracks after installation. One only lasted 3 days after being replaced. Others have lasted 3 months. There is something defective with the current Subaru replacement windshields and the dealers can't help. These are $1,300 insurance claims each. Subaru needs to figure out what is happening with the poor quality before someone gets hurt from shattered glass or impaired visibility from cracks.”
Power train
47 reports2 crashes
“The CVT failed at 62 miles per hour on a busy interstate, XXX. This caused the drivetrain to lock. The car has been repaired and traded locally in [XXX]. The car was very difficult to steer with locked wheels in traffic. This was a rapid evasive manuver on a busy interstate. An undrivable vehicle on an interstate is life threatening to many. Flat bed driver told me I was lucky to steer off of lanes onto shoulder with four locked wheels. This incident put me in mild shock. The Subaru dealer had to replace the transmission. The dealer and Subaru Regional Rep. examined the CVT failure. It was outside of the 100,000-mile warranty by about 895 miles. Repair invoice attached. I did not have advanced warning of CVT failure. There were no warning lights on before the CVT failure.”

“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…”
