According to documents posted to the Transport Canada and NHTSA websites on Monday, a software glitch may cause the optional trailer brake lights from functioning. Since it only impacts those with the optional trailer hitch installed, and we don’t know how many of them have been delivered, it is difficult to determine how big of a problem this may be.

In Canada the recall impacts just 342 vehicles, while in the US 2,567 Model Y’s are affected.

Even though the software issue will be fixed with a free over-the-air (OTA) software update later this month, the recall notice had to be issued since the vehicle fails to comply with the federal motor vehicle safety standards in the US.

Here is the full recall from Transport Canada.
