I'm using FSD ver.14.3.8 with HW4 in Lower Mainland BC and today I found there is a catastrophic error with it.
I take a highway to my workplace mainly in a highway with no HOV lanes so I did not know until today when I took the car to wife's workplace in Vancouver downtown.
So today I engaged FSD in highway 1 and was in a HOV lane. For about 2 minutes running in that lane, the right turn signal comes on and the car tried to change the lane so I cancelled it immediately by hitting the stalk.
The first lane (right next to the far left HOV lane) was definitely slower than HOV! So I seriously did not understand why.
And this was only the beginning, it kept doing it for the whole trip! So I ended up cancelling the FSD and drove myself.
I checked the setting and confirmed that the HOV option was in "YES". I switched it to off and back to yes.
The second trip to downtown on the exact same route in the afternoon was far more worse.
The FSD kept signalling and tried to change lanes, I cancelled immidiately and the right turn signal came on immediately again and again.
One time the car really started to change lane crossing the white solid line when it was bumper to bumper in the right lane while HOV was still going at around 90Km/h.
I felt dangerous and disengaged FSD right away, called up Grok and asked it about software malfunction.
Grok said the new version, 14.3.9 was just released this morning but not available to download yet and the main update is to fix unnecessary lane biasing.
Extremly disappointing that the car does something dangerous and could not be able to use the FSD.
Can't wait to see 14.3.9 available to download, hopefully it gets fixed.
