When I dug into the causes, I came across this recall and did the VIN look up on the NHTSA website and also the Subaru website for active recalls. The Subaru…

I was within the town limits so I was driving slowly. When I approached the first stop light in town I saw that it was red. There were of three or four vehicles stopped at that light. At that point I was probably only going 5mph. I took my foot off of the gas pedal and put my foot on the brake to make a slow stop. Instead, the car accelerated rather quickly. I continued to brake but the car seemed to speed up. I was able to avoid hitting the truck in front of me by going…

The cam carrier has a leak that is causing oil to slowly leak out of the car. The current issue is causing me to have to regularly add oil to the car. My safety is at risk as the car engine could fail while driving which would be me and others at risk. My understanding is that the leaking oil could also cause other parts to fail such as the O2 sensor. The recommended repair from the local Subaru dealer is to reseal the cam carrier at an estimated cost of $4,744. I attempted…

The car had a recall on it for the catalytic converter and front pipe and bellows being cracked. It was replaced under a service bulletin put out by Subaru at 104,000 miles in 2020. I just went to get the vehicle inspected in 5/2023 and the exact same part is failing once again. It will not pass inspection. This causes exhaust to leak back into the car (including carbon monoxide) given the converter/bellows are parts that come off the engine right under the…
