I've got a February 2022 build model Y which had the false camera obstructed autosteer abort problem as soon as I got FSDb running in June 2022. I had aborts at a consistent place on a major six-lane arterial road, and even once on an urban interstate. My dark neighborhood (no street lights, customarily homes show little light, almost no traffic) did not allow me to drive more than a couple of hundred feet without the red hands of death. I bought and used an IR illuminator hung from the rear view mirror, which allowed use of the system. One attempted service appointment in mid-September was closed on the grounds that the car did not log any errors for which they had solutions, and the camera obstructed error was deemed an oddity of beta software. The tech volunteered that he had never seen an IR illuminator (plainly implying they did not exist).
We got a new 3 in addition which is an October 2022 build (model year 2023). Since FSDb got installed on December 17 I've never gotten a camera obstructed autosteer abort. I've tried and failed repeatedly to detect IR illumination, so have assumed this car also lacks them.
Tonight I tried the acid test of driving around my dark neighborhood. In 17 minutes of driving I covered 3.1 miles, mostly of very, very dark roads. Zero camera obstructed alerts. I feel certain this is a different condition than the Y had all summer.
I'm puzzled. Here are some possibilities:
1. the 3 actually has IR illuminators, but my iPhone mini as used by me does not show them.
2. this 3 came with a cabin camera more sensitive to low level light than our Y
3. The software turned up the brightness of the night mode on the cabin screen enough for the camera to just get by
4. The software got clever enough to check whether the car has IR illumination, and is somehow programmed to give the user a break if things are just too dark.
My next move is to take the Y around the neighborhood. For sure that has the same cabin camera and (lack of) IR illuminators from Tesla as it always had. So if the reason the 3 works is some kind of software tweak, maybe the Y will work now also. If it does not work, then maybe I should try again to get a service appointment. Maybe since September 20 the instructions provided to the service techs have changed--or maybe I'll just get lucky and get a cooperative one, also some folks posting here have.
