April 2022 my car started to make noises when accelarating. I took it to several mechanics who could not diagnose the problem. Dec. 30, 2022 I took it to another mechanic who thought it might be the brakes and replaced them. He then test drove the vehicle and the noise remained, so he stopped at a transmission shop and they said possible transmission issues, not sure. No warning light ever came on. I was driving on Dec. 31, 2022 when the sounds were louder. I turned around to go home and was in traffic and down shifted to descend a hill when I downshifted the car stopped and many warning lights came on the dashbosrd. I shifted back into regular gear and the left lane was available so I changed lanes and pulled in to the mndot parking lot which was about 100 feet away. I shut off the vehicle and had it towed to the Subaru dealer. They diagnosed the car with a broken transmission and that since I have a salvage title it is not covered. The repair cost is over $9000.
