There was a horrible whining that started very quiet on and off in 2017 and became louder this year. We drove into a city intersection to turn, and the car stalled. We were lucky that we didn't get hit by another car. We took it to the dealership as we do all recommended maintenance and something was really wrong to make it stall like that. The dealership said that it is a CVT transmission, and they are known to have this problem. Told us to call subaru. There was an extended warranty offered in 2018, but we never were notified of that and are the original owner. If we had the notification we would have had this fixed as it occasionally made the noise but it did not repeat when at our service center. We would have had the dealer check it if we knew about the problem and warranty. I expected a Subaru to last longer than this before needing an $9,000 repair. Called Subaru and they offered me $1,000 toward a new Subaru. I paid $36,000 for this car. I don't think $1,000 off one now is going to help me very much for a known problem with this transmission that put us in a very dangerous situation.
