2018 Subaru Crostrek - I gave the dealer a letter along with a thumb drive with pictures and videos of what is wrong with my car...all computer related. This was in November 2018, one year after buying the car. I had taken the car in for the same problems many times but they said they could not fix it...had to see it in action. I took multiple videos as they requested. Today is September 20, 2019 and I have yet to hear anything about my car problems. The most annoying one is the driver or passenger seat belt warning buzzer won't stop buzzing even when you turn the car off and get out. They gave me all kinds of excuses all the times...e.g. not enough gas in the car, the door needs to be opened and then closed, the mile reader needs to be cleared...all kinds of dumb excuses for the different things that were happening. I figured once I gave them the videos and pictures with a letter explain it all again, they would contact me with something...but to this date - NOTHING. I also told them this would be my first and LAST Subaru - obviously they must figured that's not going to break them, so why bother with me.
Other than that, whenever I have to go for any other service, like oil change and such, all the service personnel are super helpful, friendly and very courteous. I do enjoy my wait time there, which is not usually very long at all. I have no doubt that they must have passed along my thumb drive and letter to the powers that be, and that's where the ball was dropped.
