At my recent service center visit, the service rep told me that many of the weirdnesses exhibited in the 17" screen apps (including nav blue-line bugs, the fact that four door handles often present even though I have it set to driver's door only, etc) are caused by the fact that my Trip B was over 46,000 miles. The day I took delivery of my S in 2013, I set Trip B, and then left it alone. I wanted to capture the lifetime Wh/mi average, and for the past 18 months have watched as I managed to get it from about 345 to 340 to 338 to most recently, 337. I was hoping to get it under 335. And now this service center guy was telling me that the computer was storing MASSIVE amounts of data for all those 46,000 miles (I got the impression it was gigabytes), and it was really dragging down performance of the computer. This seems . . . unlikely. But he was convincing enough that I said ok, and reset my cherished Trip B to zero. But I wonder. Have any of you ever heard such a thing before? Has any service center told you the same thing? Just curious if there are any facts to back up this claim. Like, some software engineer at Tesla, or a technical service bulletin at a service center. Something official.
