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.

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.

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.

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.

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.

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.
