2017 Subaru Outback engine problems

“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…”

“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…”

“Total of 3 incidents when my car had approx 1/8 to 1/4 of a tank of gas....as going up incline on interstate....car like stalls and slows down, will not speed up....get it over to the side to avoid being hit and it finally starts going again...close call with vehicles behind us in the passing lane. Below listed the last time it happened... Did not use to do this...first time was same area listed below in November 2025.”

“Car was being driven on the highway in cruise control, when the cruise control turned off and the car began to decelerate. When the gas pedal was pressed, the RPMs shot up but there was no acceleration. The car was pulled over, turned off, and we were not able to turn it on again. The car was towed to a shop, where they were able to identify the engine wasn’t working but not the root cause, and also mentioned the possibility of there being a transmission problem. We then brought it to a Subaru dealer, and they said a similar thing without being able to diagnose anything more specific. This car is 8 years old and has had routine, consistent maintenance the entire time. The surprise of an engine failure with no warning is very alarming and dangerous.”

“Hi I had my car into the local Subaru Dealership (Wheeling Subaru) a few weeks ago to investigate a couple of issues that the car has been having for years (and they have never been able to find). Over the course of that investigation, they finally were able to recreate two issues that should have been covered under the warranty since it's been happening and reported to them for years (the seat memory programming button isn't working and the right sight steering wheel controller isn't working). The parts and labor for those two issues come to $545. But the much bigger issue is that they told me the engine needs to be pulled out and resealed because of cam carrier and spark plug gasket leaks, and that repair is $5,076 plus tax. When I expressed astonishment over this and asked what is going on, the service advisor explained this is a common problem with Subaru cars from this model year because of the switch from timing belts to whatever it has now. with the CVT engine I looked around online and discovered that this is a common issue with 2017 Outbacks. I thought I was making an investment that would last when I bought a brand new Subaru rather than a Ford,…”

“PER SUBARUS BULLETIN 02-192-25 POSED ON 10-26-2024 THEY PROVIDED DETAILS ON HOW TO FIX A LEAK FROM ZONE 4 FOR CAM SHAFT CARRIER AND VALVE COVER. I HAVE A LEAK FROM THESE TWO ITEMS NOTED. I HAVE BEEN BREATHING THE OIL FUMES FOR WHO KNOWS HOW LONG. I HAVE HAD THESE ISSUES CONFIRMED BY BOTH SUBARU DEALERSHIP SERVICE CENTER AND AN INDEPENDENT SERVICE CENTER. NO ENGINE LIGHTS HAVE BEEN DISPLAYED OR CAME ON TO INDICATE ANY OF THESES ISSUES. THE ODOR OF STRONG OIL JUST GOT WORSE OVER TIME AND MY VEHICLE ONLY HAS 87000 ORIGINAL MILES ON IT AND HAS PROPER DOCUMENTED OIL CHANGE AND SERVICE EVERY 3000 MILES.”
