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.

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.

After driving the vehicle I will arrive at my destination. I will stop, continue pressing the vehicle break while moving the shifter from drive to park. Then, I turn the key to the off position in an attempt to remove my key from the Ignition. About 40-50% of the time, the key can not be removed. In order remove the key I will have to do one of the following: Option 1. Let my foot of of the break, pause, then press my foot hard on the break peddle, move to shifter from park to drive, while continuing to press my...

On July 31,2023, approximately 8PM, I was driving my 2017 Subaru slowly as I made the 90degree turn into my driveway. Midway up the driveway, the car suddenly -on its own - spontaneously accelerated , burst through the half open garage door, across the garage, and crashed through the garage wall into my family room - bulldozing through two sheets of plywood and large pieces of firewood in the garage, and then destroying heavy antique furniture in the family room before coming to rest. The jagged remains of the...

Cam carrier leak-unreliable car-detected and confirmed by Subaru dealership-no warning lights-appears to be an issue for many Subaru vehicles

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

On May 20, 2022, I was attempting to back into a parking space when my car lunged forward and crashed into two parked cars. I suffered a cracked sternum. No one else was hurt but I was just a few feet from the ground-level windows of a motel. Much body damage to my car (in excess of $13,000) and the other two cars. Police report was filed. Insurance claim filed. No reproduction of problem sought from manufacturer or dealer. No warning signals from car. Assumption made of driver at fault accident. However, please refer to Detroit Free Press article printed 4/22/23: https://freep-mi.newsmemory.com/?publink=0dd2ac172_134ab3a

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.

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.

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.

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....

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.

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...

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...

My 2017 Subaru Forester has 52,000 miles driven. Recently the ignition key will NOT turn to start the engine. The transmission was in park and all the doors were fully closed. After 15 minutes trying several times to no avail it did finally turn to the right and the engine started. Also, previously a few times, randomly, the key would not turn all the way to to the left to turn the engine off. Again, the car was in park and I kept my foot on the brake while trying. Each time this happened I had to move the...

With engine running and shift lever in Park (CVT transmission) driver is unable to turn the engine off or remove the ignition key from the steering wheel. This occurs sporadically/unpredictably such that driver has no forewarning and cannot take proactive steps to avoid the problem, resulting in instances where driver is forced to leave the car running in situations that present safety concerns. (Examples: in a garage or enclosed area; when temporarily exiting vehicle necessitating leaving the doors unlocked;...

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

Periodically unable to remove key from the ignition. Has been happening more frequently over the past 2 months. Key is "locked" in ignition, unable to completely "turn off" key switch and therefore unable to remove the key. Only resolution has been to turn the vehicle back on and shift the gears and reattempt to turn car off and remove key. This is also, likely, affecting being able to use the remote start for my vehicle.

The vehicle was traveling along the highway at around 65-75mph and we went up a grade (cuesta grade) along 101 freeway in california and vehicle had a sudden loss in power while climbing up the hill. Ultimately, no power was ever regained and the vehicle shut off completely and stopped. We were stuck on the side of the road and had to call 911 to have a chp offer park behind us so that we would not be hit because we were partially in the lane. The car could not move so we had to have it towed to a subaru...

There is a problem with the engine and the fuel feed. The engine will buck, much like a backfire and fail to accelerate. This problem has been on-going since we purchased the vehicle. The date of the event is an approximation but it has been on-going since we purchased the car.

My fianc and I bought this car and we were told it was not an accident, after we purchased it we found out that it had been in 2 accidents and during driving 1 night it bucked real hard and would now accelerate and it scared both of us. So the next day I took it to center subaru in torrington connecticut to get it inspected, during the trip to the dealer it had bucked three more times violently. I told them about it and they could not find any codes in the system, I spoke with the mechanic later and he said if it...
