Forester in known for chronic exhaust leak into cabin through AC vents. Reported this to dealership and they "could not find the problem." Cabin of vehicle smells heavily of exhaust. Driver gets headache from smell/gas while driving. Internet forums show this is a common unaddressed issue by dealerships. Car is a 2017 and should not be leaking exhaust into the cabin.
While driving on the highway at 65 MPH another vehicle cut me off causing me to apply my brakes. Car came down to about 20 MPH. Then I attempted to accelerate and the car would not accelerate. I pulled off on the shoulder to check. Everything seemed okay. There was no error codes on the dashboard. I pulled back on the highway and the car accelerated fine. I went in to talk to Subaru service in Jersey City. He said maybe the computer needed to reset itself. Doesnt sound right to me. Something wrong if a defect exist where the computer needs time to reset itself in an emergency braking esp if you have to accelerate on the highwway
Cam carrier leak-unreliable car-detected and confirmed by Subaru dealership-no warning lights-appears to be an issue for many Subaru vehicles
I have a 2017 Subaru Forester Touring. It has stalled on acceleration twice. Once on a divided highway attempting to increase speed going up slight incline around 60mph. It stalled and shut off. It also stalled but didn't completely shut off going through an intersection at 45mph today.
Exhaust fumes noticed in the passenger cabin of the vehicle. PZEV equipped. I have heard of others experiencing the same issue. This was noted some time ago, however parts were not available at the time and Subaru N.A. had not responded to my written correspondance until i finally phoned them. Very concerned about potential for Carbon Monoxide. I understandf Ford explorer and VW had similar issues. The attached estimate was recently obtained from the dealership but service rep claimed this was the recommended service at time of discovery.
The catalytic converter had substantial rust and was beyond repair (i.e., welding). The vehicle was only 6 years old and did not have any issues with rust identified during the 2021 annual inspection (as required by our state). This year, the vehicle failed inspection due to the amount of damage from rust. Our mechanic advised the rust was most likely caused by the plastic covers surrounding the catalytic converter not allowing enough air to circulate to keep the area dry / prevent rust from forming.
Noticed sputtering in my car. Took it to dealership. I was told I needed condenser and compressor. When googled, there was a recall for condenser for Subaru Forester 2017 model. The dealership told me that it’s only vin# specific for that reason not covered under recall. That was a shock. Same model and year but they would only cover certain vin #? For the same known issue? Why? It should cover all vin # for the safety of the consumer. I am writing to report the issues encountered so far with this vehicle. 1. Batteries were leaking prematurely, I got it replaced 4 months ago 2. Need condenser and compressor replaced at less than 60,000 miles for a newly car purchased car from dealership. Please look in to this issue if reported by more consumers for safety reason and also to hold the company accountable for faulty parts. Thank you.
The exhaust pipe assembly for our 2017 non-turbo Subaru Forester has failed. Two other similar complaints for this model and year vehicle have been submitted to NHTSA (ID#’s 11429564 and 11395158). Exhaust fumes spread within the vehicle cabin and presents a significant safety and health issue for occupants. A similar problem has been reported for turbo charge vehicles for which Subaru issued a voluntary emissions recall on March 27, 2020. No such recall for non-turbo vehicles has been issued by Subaru. The vehicle will be inspected by the local dealer. I request NHTSA investigate this issue and request Subaru expand its voluntary emissions recall to non-turbo vehicles.
My subaru forester started smelling and rattling loud. My mechanic told me it could be the muffler. I took it to the muffler shop and it was the catalytic converter. I had to pay $800 to fix it but my friend who had the same exact car had it replaced at Subaru for free. My car is under 8 years old and 100,000 miles. I read that it should be covered by Subaru. I called them and they never replied and wanted to charge $299 just for a diagnostic check. There should have been a recall notice on the Subaru Forester 2017. It's catalytic converter is faulty. I had to smell the fumes and so did my grandson.
I was pulling into a parellel parking space, braking to slow to a stop when my car surged froward inspite of increased and continued braking and hit the car in front of me. The collision is what stopped the car. My Subaru Forester is very damaged (bumper, lights, and frame rail) and the car in front also had extensive damage. My safety and the safety of the neigbhorhood cars, pedestrians and homes was at risk given my car was unstoppable despite braking. I couldn't understand what happened so I did an internet search for acceleration while braking and many articles came up reguarding several Subaru models (including mine) of "sudden unintended acceleration" issues. What was described was exactly what I experienced. There are several class action lawsuits in the works as Subaru has not taken any responsibility. No dashboard warning lights came on before or after the crash. I took the car to the Subaru dealer I purshased it from. At first they said there would be a 250. dollar diagnostic fee. When I picked it up they said there was an ECM (Engine Control Module) update and they performed it on my car. The update was designed "to address problems" like those I described. The clerk would not elaborate, was very vague and would say nothing beyond that except he didn't know if the update would fix the problem-that we would just have to wait and see. I explained that if it happened again it could have catastrophic consequences, he had nothing to say. He waived the service fee. I got the impression Subaru didn't want to say much because they would be responsible. By waiving the fee they hoped I would just go away. I am left with: a severely damaged car, as is my neighbor's, an accident that looks to be my fault-when in fact it is Subaru's fault, a large deductable to pay, a point on my lisence and increased insurance rates, and a car I have no faith in. This should not be on my driving record. Subaru should be found responsible.
I started noticing exhaust fumes in the cabin while idling at a stop. I did some research and found that several Foresters have had an issue with their exhaust manifold bellows cracking on a flexi pipe. So I started looking for a leak. I took the plastic underbody engine cover off and took off the heat shield and located the crack on the flexi pipe. The flexi pipe have been replaced at approximately 60k miles. It lasted for approximately a year or another 30K miles and I had to replace it again. My vehicle currently has 160K and the same issue comes back. It is very frustrating because I feel very lightheaded when driving this vehicle and replacement of this part is very expensive. $1800 for the full manifold.
EXHAUST MANIFOLD CRACKED AND NEEDED REPLACED; WAS FIRST ADVISED THAT THE CATALYT CONVERTER WAS BAD AND WOULD NEED REPLACED BY A NON SUBARU SERVICE PROVIDER. WHEN I TOOK TO SUBARU DEALER, WAS ADVISED I HAD TO PAY FOR 2 HOURS LABOR TO "DIAGNOSIS" THE EXHAUST BEFORE THEY COULD ADVISE OF ISSUE/FIX; DID NOT DO AT THAT TIME. NEXT SUBARU MAINTENANCE REQUESTED TO HAVE SITUATION DIAGNOSED; WAS THEN ADVISED THAT DID NOT NEED TO REMOVE COVERS TO DIAGNOSIS, THEY KNEW IT WAS THE EXHAUST MANIFOLD. PART WAS ON BACKORDER; ORDERED AND THEN REPLACED; EXHAUST STILL LOUD AND NOW HAVE FUMES THAT WERE NOT PRESENT PRIOR TO THE REPAIR
WE HAVE A 2017 SUBARU FORESTER XT TOURING MODEL 2.0 TURBO ENGINE WITH APPROXIMATELY 20,000 MILES. WIFE AND SON WERE TRAVELING TO A WEDDING WHEN CHECK ENGINE LIGHT CAME ON NO SOONER DID LIGHT COME ON HEAVY SMOKE FILLED INSIDE OF CAR FROM AIR VENTS HEAVY SMOKE WAS COMING OUT FROM UNDER HOOD ALSO WAITED FOR SMOKE TO CLEAR NOTICED OIL ALL OVER ENGINE HAD VEHICLE TOWED TO SUBARU DEALERSHIP SERVICE MANAGER CALLED AND SAID THERE WAS A HOLE IN ENGINE BLOCK I ASKED HIM HOW COULD HAPPEN HE SAID IT COULD BE FAULTY ENGINE THIS VEHICLE IS A FIRE HAZARD MY FAMILY COULD OF BEEN SERIOUSLY BEEN INJURED IF VEHICLE CAUGHT FIRE WHILE THEY WERE DRIVING OR PASSED OUT DUE TO HEAVY SMOKE INSIDE VEHICLE WAS IN MOTION TRAVELING ON PAVED BLACK SURFACE ROAD THIS VEHICLE SHOULD BE RECALLED COMPLETELY. *TR
WHILE DRIVING MY VEHICLE WANTS TO STALL AND I HAVE TO FLOOR THE GAS PEDAL AND IT SLOWLY STARTS TO ACCELERATE. I'M AFRAID THAT ONE OF THESE DAYS IT WILL NOT ACCELERATE AND WILL CAUSE A FATAL ACCIDENT. I BROUGHT IT IN TO PINE BELT SUBARU IN LAKEWOOD, NJ FOR SERVICE AND THEY SAID THE SOFTWARE NEEDS UPDATING AND THEY UPDATED IT. HOWEVER, IT'S STILL STALLING. THIS STALLING HAPPENS MANY TIMES. THE LAST TIME WAS ON 03/22/2019.
2.5 MANUAL, BURNS OIL AT EXCESSIVE RATE. CHECK ENGINE OIL LIGHT TURNED TWICE SO FAR, ONCE AT 2K MILES ON A CAR AND NEXT TIME AT 16K MILES. BOTH LIGHTS WERE WELL WITHIN THE OIL CHANGE SCHEDULE AND THE CAR HAS NOT BEEN SUBDUED TO ANY UNUSUAL USE. UNABLE TO TRAVEL IN THE CAR LONG DISTANCES WITHOUT HAVING 2 QUARTS OF OIL IN A TRUNK DUE TO POSSIBLE ENGINE FAILURE FOR LACK OF OIL. BOTH TIMES THE LOW OIL LIGHTS WENT UP WHEN TRAVELING ON ROADS AND SUNARU DEALER HAD TO ADD OIL (STILL UNDER WARRANTY).
I DID MY FIRST OIL CHANGE AT 1500 MILES, THEN THE NEXT TWO CHANGES AT ABOUT 3000 MILE INTERVALS. THEN I DECIDED TO STRETCH THEM TO THE 5K MILES RECOMMENDED BY SUBARU. I WAS ABOUT 4K MILES INTO THIS CHANGE INTERVAL WHEN MY OIL LEVEL LIGHT CAME ON. I CHECKED THE DIP STICK AND IT WAS BONE DRY. I WOULDN'T HAVE NOTICED OIL CONSUMPTION ON THE FIRST FEW CHANGES BECAUSE I WAS DOING THEM MORE FREQUENTLY THAN NEEDED AND THEREFORE THE ENGINE DIDN'T HAVE TIME TO CONSUME ENOUGH OIL TO TRIP THE LOW OIL LIGHT. I WENT TO SUBARU FOR AN OIL CONSUMPTION TEST, WHICH IT "PASSED". I DOCUMENTED EVERYTHING AND TOOK PHOTOS OF THE DIP STICK BEFORE AND AFTER THE TEST. SUBARU FILLS YOUR OIL TO THE TOP LINE OF THE DIP STICK. THE MECHANIC INFORMED ME THIS IS STANDARD PROCEDURE. I WAS TOLD THAT THE AMOUNT OF OIL BETWEEN THE 2 LINES IS A QUART. AFTER THE 1200 MILES OF THE OIL CONSUMPTION TEST, THE OIL LEVEL WAS DOWN ABOUT 20% BETWEEN THE TWO LINES. TAKING THAT OUT TO A FULL 5-6K MILE INTERVAL, THAT MEANS IT BURNS ABOUT A QUART OR MORE IN BETWEEN CHANGES. I SPOKE WITH THE MECHANIC WHO SAID THAT THIS IS COMPLETELY WITHIN SPEC OF SUBARU'S STANDARDS. I TOLD HIM I THOUGHT THIS WAS A LOT, BUT HE SAID THIS IS NORMAL FOR SUBARUS IN HIS EXPERIENCE. A CAR WITH ONLY 16K MILES SHOULD NOT REQUIRE OVER A QUART OF OIL TO BE ADDED BETWEEN OIL CHANGES. WHEN MY OIL LIGHT CAME ON AGAIN, WITHIN THE SAME OIL CHANGE INTERVAL AS THE OIL CONSUMPTION TEST (ABOUT 4K MILES INTO THE INTERVAL), I TOOK THE CAR BACK TO SUBARU FOR A SECOND OIL CONSUMPTION TEST. INSTEAD OF PERFORMING THIS, THEY OPTED TO REPLACE MY SHORT BLOCK, A VERY EXTENSIVE REPAIR. I AM STILL WAITING FOR THIS REPAIR TO OCCUR UNDER FACTORY WARRANTY.
VEHICLE HESITATES DURING ACCELERATION, WORSE IF AC IS ON. ENGINE NEARLY STALLS, LOSING POWER. INITIALLY HAPPENED DURING LEFT TURN AND WHILE VEHICLE IS IN MIDDLE OF INTERSECTION IN FRONT OF ONCOMING TRAFFIC. THIS IS REPEATED ISSUE OVER SEVERAL MONTHS
