Sounds like the differential in the transmission is making a horrendous noise
My clutch fork was nearly broken in two.(pics available). I asked the mechanic to save the old parts. My 6MT was never modified; the vehicle was neither raced, taken off-road nor used for towing. A friend discovered the following article online: [XXX] Based on said article , I believe the part on my vehicle was defective. How may other manual transmission Subarus have been affected by this defect ? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2015 Subaru Forester. The contact stated that while driving at high speeds, the vehicle made abnormal grinding sounds. Additionally, the vehicle was vibrating while turning the steering wheel. The vehicle was taken to the dealer, where it was diagnosed with a faulty bearing. The bearing was replaced; however, the failure recurred while driving approximately 70-75 MPH. The vehicle was then taken to Farrish Subaru (10407 Fairfax Blvd, Fairfax, VA 22030) where it was diagnosed that all four bushings needed to be replaced. The dealer replaced the four bushings. The manufacturer was not made aware of the failure. The failure mileage was approximately 71,545.
Both Rear Wheel bearings failed and required replacement at 65,000 miles. Apparently this is a common issue as a TSB was issued and a new backer plate was installed as water is getting into the bearings (design issue)
The contact owns a 2015 Subaru Forester. The contact stated while driving 40 MPH, the vehicle accelerated at high speed and stability, the traction control, the check engine, and the cruise control warning light illuminated, and the vehicle would not accelerate. The contact turned off and restarted the vehicle and the vehicle operated normally. The vehicle was taken to the dealer, but no failure was found. The contact stated that the failure reoccurred. The vehicle was taken to the dealer and the transmission module was updated, but the failure reoccurred. The vehicle was taken to the dealer and the throttle pedal assembly was replaced multiple times, but the failure persisted. The manufacturer was contacted, and a case was filed. The failure mileage was 73,600.
Transmission faiure at 112,000 miles
The contact owned a 2015 Subaru Forester. The contact stated that while driving at 10 MPH, in a residential parking lot, the contact stated while he was parking, the vehicle independently accelerated and crashed into a nearby tree. The contact stated before crashing into the nearby tree the vehicle also hit a nearby pole. The contact stated that the acceleration continued to get faster and faster. The contact also stated that none of the air bags deployed. A police report was filed. The contact's wife was transferred by ambulance to a hospital for medical attention. The contact's wife suffered a compression fractured vertebra and she had been experiencing severe pain. A police report was filed. The vehicle was towed to a tow yard. The vehicle was condemned to total loss by the insurance company. The manufacturer was made aware of the failure. The failure mileage was approximately 75,000.
APRIL 2022 MY CAR STARTED TO MAKE NOISES WHEN ACCELARATING. I TOOK IT TO SEVERAL MECHANICS WHO COULD NOT DIAGNOSE THE PROBLEM. DEC. 30, 2022 I TOOK IT TO ANOTHER MECHANIC WHO THOUGHT IT MIGHT BE THE BRAKES AND REPLACED THEM. HE THEN TEST DROVE THE VEHICLE AND THE NOISE REMAINED, SO HE STOPPED AT A TRANSMISSION SHOP AND THEY SAID POSSIBLE TRANSMISSION ISSUES, NOT SURE. NO WARNING LIGHT EVER CAME ON. I WAS DRIVING ON DEC. 31, 2022 WHEN THE SOUNDS WERE LOUDER. I TURNED AROUND TO GO HOME AND WAS IN TRAFFIC AND DOWN SHIFTED TO DESCEND A HILL WHEN I DOWNSHIFTED THE CAR STOPPED AND MANY WARNING LIGHTS CAME ON THE DASHBOSRD. I SHIFTED BACK INTO REGULAR GEAR AND THE LEFT LANE WAS AVAILABLE SO I CHANGED LANES AND PULLED IN TO THE MNDOT PARKING LOT WHICH WAS ABOUT 100 FEET AWAY. I SHUT OFF THE VEHICLE AND HAD IT TOWED TO THE SUBARU DEALER. THEY DIAGNOSED THE CAR WITH A BROKEN TRANSMISSION AND THAT SINCE I HAVE A SALVAGE TITLE IT IS NOT COVERED. THE REPAIR COST IS OVER $9000.
My transmission is having issues after being repaired by dealer. It is stalling when I try to accelerate leaving me at risk of being rear ended.
The contact owns a 2015 Subaru Forester. The contact stated while his wife was driving approximately 55 MPH, the vehicle started shaking abnormally. The contact stated that his wife smelled like the brakes were burning. The contact stated that his wife did not notice any warning lights being illuminated. The driver pulled over and turned off the vehicle; however, the vehicle failed to restart. The contact had the vehicle towed to an independent mechanic. The vehicle was diagnosed, and it was determined that the clutch flywheel had fractured and separated. The mechanic also stated that the clutch plate needed to be replaced. The vehicle was repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 40,300. The consumer stated the flywheel was in two pieces and outer two pieces broke apart, destroying the clutch assembly.
Car continues to have ongoing lack of response with acceleration. Car was at dealer for 3 weeks for inspection after I was nearly rear ended due to lack of response in acceleration at a stop light, as well as shifting gears. No lights came on to indicate issue, thus the car was returned to me with no repairs. 2 weeks after car obtained from dealer, car again started having issues with acceleration, and pulling into a lot, the AT oil temp light, hill assist, ABS, and check engine light came on. In the 2 prior attempted repair sessions at dealer, the team stated that they were unable to replicate the problem that has been occurring nearly daily for almost 2 months, and stated that they cannot figure it out without any lights coming on. Given the lack of responsiveness to accelerate, my safety is at-risk as well as others, as I am not able to clear traffic as quickly as I should.
While attempting to make a left turn the car stalled and lost all power. The car had to be restarted and was able to drive back home. Took the car to dealership who stated it was a battery issue and a plugged air filter. NO check of the transmission was completed. This is the CVT transmission. The battery is 6 months old and the battery was tested multiple times by other locations and tested good. This stalling making a turn seems to be an ongoing issue with Subaru and the CVT transmission.
Hill start assist system failure. Apply power, but the car would not go very far before the brakes were automatically applied. Pull out into traffic and the car would not go. Dangerous. Warning message that the system hill start assist should be inspected by a Subaru dealer. Drove on deserted city streets for two minutes and then everything was okay except the warning light stayed on until I got home and turned the car off. I have found out how to deactivate the hill start system and I will do that. I have not yet taken the car to the dealer.
PREMATURE WHEEL BEARING FAILURE, SUBARU ALREADY HAS A SERVICE BULETIN (#05-70-19 ANNOUNCED ON SEPT 30, 2019) RECOMENDING INSTALLING REVISED BRAKE BACKING PLATES DUE TO FACTORY INSTALLED NON-FLAT BACKING PLATES WHICH DISTORT THE REAR WHEEL BEARINGS/HUBS CAUSING PREMATURE WHEEL BEARING FAILURE. THIS IS A WELL DOCUMENTED OCCURANCE NOTED ON NATIONAL SUBARU WEB PORTALS FOR MULTIPLE MODELS WITH POSSIBLE CATASTROPHIC OUTCOMES.
We were driving on the highway going 65 and then there were two quick shudders and jerks of the car. Seemed to lose power in those moments. Immediately after that, we could hear a faint whoosh sound when on the accelerator but the car did accelerate. That sound was not there before the shudders. Then about 30 seconds later the power gave out and the car started slowing down very quickly. Luckily we were in the right lane and could pull off to the shoulder quickly, though the shoulder was very narrow and dangerous. The car slowed down very quickly without applying that much brake. When we were stopped on the shoulder, I applied the accelerator, and the car was in Drive, and it didn’t go anywhere. Then we put it in park and the car rolled forward. So both the drive and park gears were not working. We turned the car off and then back on to try the gears again. Same issues happened again with drive and park. This was a very dangerous situation that occurred quickly on a highway. The issue described and what we experienced seems to be consistent with similar issues with other CVT transmissions. We hope the NHTSA follows up with Subaru as we will be as well.
My 2015 Subaru Forester developed a high pitch noise emanating from the rear of the vehicle. The vehicle currently has less than 50,000 miles on the odometer and I am the original owner. I discovered that Subaru has issued a TSB regarding the issue (NUMBER: 05-70-19). The noise is loud and distracting and it appears that a complete bearing failure is imminent. Subaru should extend the powertrain warranty for this item to 10 years and or 100,000 miles and cover any owners previous repair costs.
Key will not remove from ignition when put in park. Happens about 40-60% of the time and must shift several times in and out of park to get key out of ignition. This is a known faulty part with several models (see Subaru Service Bulletin 16-112-18R) yet Subaru has not issued a recall. Replacement of known faulty part is at customer's expense. Safety issue - unable to exit car upon parking.
Merging onto a a 70mph highway and vehicle stopped accelerating around 45 mph. RMPs kept increasing, black smoke-type substance was coming out of the exhaust pipes when I tried to accelerate. No lights, warning noises, or any other indication of anything wrong with the car. Vehicle kept lurching and rev'ing but no acceleration.
ROUGH IDLING, UNEVEN ACCELERATION WHEN STEPPED ON GAS, THE CAR WOULD ACCELERATE, SLOW DOWN, AND ACCELERATE AGAIN. UNEVEN DECELERATION WHEN LETTING GO OF GAS, THE CAR WOULD SLOW DOWN, SPEED UP, AND SLOW DOWN AGAIN. SEEM LIKE A SOFTWARE PROBLEM WITH COMPUTER.
USING CRUISE CONTROL AT 77 MPH IN FAST LANE OF I95 NORTHBOUND FROM FL WHEN, APPROX 10 MILES SOUTH OF VA BORDER, I FELT A SNAP LIKE PULL IN VEHICLE - KIND OF LIKE A ROPE BREAKING WHEN PLAYING TUG OF WAR. THE RPMS INCREASED AND CAR RAPIDLY LOST SPEED AND WOULD NOT ACCURATE. FORTUNATELY, I WAS ABLE TO SAFELY PULL OFF I95. I NOTICED ALL LIGHTS ON DASH WERE ON AND CAR WAS RUNNING. I TURNED IT OFF, APPROX 15 TO 30 SECONDS AFTER PULLING OFF HIGHWAY. AFTER I TURNED CAR OFF, IT WOULD NOT RESTART. I WAS TOWED (INNERSTATE TOWING) TO A TOYOTA DEALERSHIP IN ROANOKE RAPIDS, NC DUE TO NO SUBARU DEALERSHIP. TOYOTA TECH LOOKED AT CAR AND CAR STARTED FINE. THE MECHANIC FELT THE TRANSMISSION OVER HEATED. I THEN LIMPED ALONG TO SUBARU DEALERSHIP IN COLONIAL HEIGHTS, VA. I TRAVELED IN SLOW LANE ON I95, AT NO MORE THAN 70 MPH, WITH A FULL TANK OF GAS AND NO ISSUES. A SUBARU TECH DRAINED FLUID AND FOUND METAL. IT WAS DETERMINED THE TRANSMISSION NEEDED REPLACED. WHILE AT TOYOTA DEALERSHIP, I CONTACTED THE LOCATION WHERE I PURCHASED MY SUBARU FORESTER AND THAT TECH INDICATED IT WAS A FAULTY FUEL PUMP OR TRANSMISSION. WHEN CAR LOST SPEED, I HAD TWO FUEL BARS LEFT. I AM NOW GETTING THE PUMP TESTED AS WELL. FORTUNATELY, MY CAR IS UNDER WARRANTY DUE TO SUBARU'S EXTENSION BUT I FIND THIS UNACCEPTABLE. I COULD HAVE EASILY BEEN KILLED IN AN INSTANT. THIS IS MY 3RD SUBARU AND I HAVE HAD MORE PROBLEMS WITH THIS ONE THAN MY TWO PREVIOUS CARS COMBINED. FURTHER, I KEEP GOING UP IN MODELS AND PRICE POINT BUT THE QUALITY HAS DECLINED. I AM A LOYAL SUBARU CUSTOMER BUT I THINK THIS MODEL MAY BE MY LAST. BECAUSE NOTHING SEIZED UP AND NO LOUD BANG, JERKING, OR RATTLING; I AM BEGINNING TO SUSPECT IT WAS THE FUEL PUMP AND I COINCIDENTALLY THE BAD TRANSMISSION WAS DISCOVERED. NO BELTS WERE BROKEN AND THE SNAP LIKE NOISE IS UNKNOWN. I HAVE NO INVOICES YET AND POLICE WERE NOT CALLED. I AM DRIVING A LOANER CAR.
NOTICED A CLICKING SOUND WHEN TURNING RIGHT. TOOK IT TO SUBARU AND THEY REPLACED THE RIGHT FRONT AXLE IN DECEMBER 2018. ALMOST A YEAR LATER, I NOTICED A CLICKING SOUND WHEN TURNING LEFT. TOOK IT TO A DIFFERENT MECHANIC AND THEY REPLACED THE LEFT FRONT AXLE. THERE WAS NEVER ANYTHING LEAKING FROM MY CAR. IT IS MY UNDERSTANDING THAT AXLES TYPICALLY LAST THE LIFETIME OF YOUR VEHICLE.
MY CAR DASH LIGHTS, HILL ASSIST AND ENGINE LIGHT, REMOTE NOT FUNCTIONING. THOUGHT IT WAS THE BRAKE SWITCH RECALL. THE CODE READ A SECONDARY PRESSURE CODE. NOT COVERED FOR REPAIR, 132,000 MILES. OTHER CARS FAILED EARLY, 50 TO 90 THOUSAND MILE. APPEARS TO BE AN ISSUE, EVEN WITH THE EXTENDED WARRANTY. NOT RELIABLE, 45 YEARS NEVER LOST A TRANSMISSION, AND AT THE TUNE $7000.00 TO REPAIR.
VEHICLE WON'T START UNLESS GEARSHIFT LEVER IS MOVED FORWARD WHILE ALREADY IN THE PARK POSITION - WITH JUST HAND PRESSURE ON THE HANDLE.
ABOUT 2 WEEKS AGO MY CAR DID SOME BUCKING AND SHUDDERING AND THE TRANSMISSION LIGHT CAME ON WHEN TAKING OFF FROM A STOPPED POSITION SO I TOOK IT INTO THE DEALERSHIP AND THEY SAID IT NEEDED NEW TRANSMISSION THAT'S GONNA COST $9000 MY VEHICLE DOES HAVE A 150000 MILES ON IT BUT IT'S NEVER BEEN OFF ROAD AND ALL THE MILES ON IT HAVE BEEN HIGHWAY MILES DRIVING ON THE INTERSTATE NOT CITY STOP AND GO
WHILE DRIVING MY WIFE NOTICED A LOSS OF POWER TO THE CAR ON HER WAY TO WORK AND LUCKILY DIDN'T GET REAR ENDED BUT AFTER A BIT THE CAR DROVE NORMALLY. ABOUT TWO WEEKS LATER DRIVING ON THE HIGHWAY THE CAR STARTED TO RATTLE AT NORMAL HIGHWAY SPEEDS BUT ONLY WHILE CAR VEERED LEFT AND NOT ON NORMAL CITY SPEEDS. TOOK THE CAR IN AND WAS TOLD THAT THE TRANSMISSION IS THE ISSUE AND HAS TO BE REPLACED WHICH I HAVE NO CHOICE BUT TO REPLACE AND AVOID SOMETHING MORE SERIOUS. I HAVE LOOKED UP THIS ISSUE AND FOUND THAT THERE ARE A LOT OF COMPLAINTS REGARDING TRANSMISSION ISSUES WITH SOME PEOPLE HAVING VERY CLOSE CALLS. THERE WAS AN EXTENSION TO THE WARRANTY PROVIDED BY SUBARU BUT PROBLEM HAS COINCIDENTALLY STARTED AFTER THE WARRANTY ENDED. EVEN THOUGH I GOT LUCKY AND NOTHING HAPPENED TO THE VEHICLE OR ANYONE I STILL THINK THIS IS A SERIOUS ISSUE THAT SHOULD BE ADDRESSED BEFORE SOMETHING WORSE HAPPENS TO SOMEONE. SUBARU SEEMS TO HAVE KNOWN THERE WAS AN ISSUE AND INSTEAD OF DOING SOMETHING THEY OFFERED A LIMITED EXTENDED WARRANTY THAT EXPIRED BEFORE THE TRUE PROBLEM BEGAN TO OCCUR.
