I have a late December 2016 model S D75. I have been having problems with the speed limit detection freezing at 25 mph and then not changing after I leave my neighborhood. When I try to activate autopilot (on the highway) it drops me to a top speed of 30 mph. I did not have this problem for the first 7 to 8 months of ownership. Tesla claims it is the GPS but it seems to be a software glitch and resolves on reboot. Has anyone else had this experience?

If the change has happened after a firmware update then I think your Service Center is correct.

The firmware limits your maximum autopilot speed based on a location.

Whoever writes the code and defines what those locations are would result in a change when you got your new firmware update.

There might be a reason why those code writers did that or it might just be a mistake.

Service Center can't do any thing about that because that is the judgement of the firmware team.

In that case, hopefully, the limit will be lifted next firmware update.
