NHTSA Complaint #11710071 — 2022 TESLA MODEL Y

In 9/2025 I noticed that the vehicle software was defaulting to a speed limit of 55 mph. I noticed that when in any form of autopilot and FSD it would accelerate to that speed. This happens in any situation before the car encounters a sign or an area that it's internal map corrects it, which is not common outside of major routes in Idaho. This includes paved marked roads, graded roads, single track dirt roads, my driveway and garage. Sometimes the car controls it's speed consistent with conditions, sometimes not. It can happen unexpectedly, and that's the issue. Where I have learned this is a problem, I of course turn off the AP or FSD and drive myself, however, if I am in driver assist mode and things are going well and the speed limit in the vehicle changes suddenly to the default 55 mph, it can take a moment for me to react. In October 2025 I reported this to my Tesla Service center as well as Tesla's over the air and on line email reporting options (from which I got no response). The service center entered a ticket directly with Tesla, and told me that that Tesla was aware. The explanation that came back was that it was due to a mapping update for the internal map of the car. They said it was the result of Google Maps setting the default speed limit in Idaho, which is where I live, to 55 and that this was due to a September 2025 update. They said it might be corrected with the next update, which has not occurred at this point (January 2026). This speeding behavior can happen suddenly and unexpectedly and seemingly randomly, and has the potential to injure pedestrians, the driver, and property, not to mention that it is also exceeding by far the legal speed limit. Drivers from other areas that may not be aware of the issue are likely to be caught unaware. There is absolutely no reason for the default speed to be 55, ever. It's unsafe, and unnecessary. It is rare to see a speed limit of 55 at all in Idaho. Most of the roads are above or below that speed limit.
