2 Manifold/header/muffler/tail Pipe problem of the 2017 Subaru Forester

Failure Date: 01/04/2021

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.

7 Manifold/header/muffler/tail Pipe problem of the 2004 Subaru Forester

Failure Date: 01/05/2015

To whom it may concern, hello, I am the owner of a 2004 Forester xt which I love. I've owned the car for almost a year and its been nothing but reliable up to this point. The weather outside is frightful, and with that comes a common problem for many Subaru owners. During the cold snaps, say below 20â°f, there is strong fuel smells which fills the cabin. It only happens during start-up, and lasts about 15 mins before the car warms up. From searching many forums and internet threads it seems this problem has been occuring since early 2001. There was a recall notice (wvk-21)for the 2002 -2003 wrx's which had a same problem I am experiencing now. Unfortunately a recall was never issued for later model Subarus which suffer the same problem. The problem is fuel leaking from 5 main fuel lines going into the intake manifold. It seems that when it is cold outside, the lines are shrinking and is allowing fuel to spew out everywhere. Just from searching for 3 days I've seen 125 cases of this happening to other owners. Will you please put out a bulletin before someone dies from there car exploding because of extra fuel leaking out of the fuel hoses. Please I beg of you, please issue a recall!!!.

10 Manifold/header/muffler/tail Pipe problem of the 2009 Subaru Forester

Failure Date: 10/03/2012

I was driving to work, and the car wouldn't accelerate, it also handled roughly. The check engine light, cruise control light was flashing, along with vehicle dynamics control warning light. I had my car towed, as it wasn't drivable. My local garage repaired my car, I received 4 new spark plugs, and an air filter. 9 days later the check engine light came on, as well as the cruise control light, and the vehicle dynamics warning light, again it was repaired, this had to do with the catalytic converter message, but all my local garage could find was a small leak near the manifold that they repaired. 2 days later the check engine light went on again, I now called my Subaru dealership, they replaced a faulty catalyst converter, and af sensor, the also changed my oil, as it was due, and suggested I have a transmission fluid flush and refill, and that my rear and front differentials, needed a drain and refill. 5 days passed another check engine light, this time it was flashing, I had to have my car towed, the Subaru dealership discovered the wrong spark plugs were put in initially, and replaced them with platinum tip spark plugs that my model takes. 4 days passed another check engine light, with being unable to accelerate, I was going up hill, so I continued on, to reach a parking lot, I could stop in but suddenly, it felt like something unblocked, this made the check engine light go away, until 2 days later, another check engine light, I once again brought my car back to the dealership, the mentioned something about the catalyst converter, but said it was 'too soon" so they left the work order open , in case it occurred again,and gave me this lecture about the grade of gas I am buying. 4 days later the check engine light returned, this time Subaru discovered the my other O2 sensor was faulty, and they would replace it, when the part comes in.

12 Manifold/header/muffler/tail Pipe problem of the 2003 Subaru Forester

Failure Date: 06/29/2007

Latches on the forrester cannot be opened unless you have a key fob. There is no way to access the tailgate without the battery operated fob. If you have a child that gets into the car without your knowledge, or if there is an accident and the doors will not open from the side. How will you get out the back--there is no way to even access with a key from the outside. If you are in an accident and you loose track of your fob too bad, you can't get out from the back. I myself carry dogs in crates in the back of the forrester. Had I realized that when I have crates, or any other large item in back you do not have access to the back, I would have never purchased the car. I believe this is a safety issue. I called the dealer and asked how to open the back of the car and they said you have to remove a panel. If you are on fire--you have to wait to get the panel off to get the door open, but if you can't get to the back because of dog crates, baby carriages, cribs, playpens etc. How would you get out. I would like to give a written hard copy report. 2. Subaru knows there is a problem with the headgasket? manifold gasket that there is a defect. When it goes bad, you make the fix it will never happen again--why does the owner have to foot the bill when I was told, by the mechanic, that in fact Subaru knows this and it is only a matter of time before the gasket will go, but once you make the correction it will never happen again.

13 Manifold/header/muffler/tail Pipe problem of the 1999 Subaru Forester

Failure Date: 10/15/2005

The contact stated since purchase of the vehicle there has been antifreeze smell. He would periodically check the reservoir, and once he noticed it was leaking. He took the vehicle to a mechanic, who determined the head gasket was leaking. There was manufacturer recall wwp-99, for this problem, but when he took the vehicle to the dealership they stated there was no problem with the vehicle. They told the contact he probably filled the reservoir too high, causing the leak. The manufacturer was contacted, and suggested he keep an eye on the problem. If it persists, they will fix the vehicle under the recall. The vehicle has not been repaired.
