The 2018 Porsche 911 GT3 has two recalls, the more notable being an owner's manual issue where child restraint installation instructions lack enough detail, which can lead to an improperly secured child seat and raise the risk of injury in a crash.
The second recall is a compliance matter for Canadian-market vehicles: the rear reflex reflectors are mounted below the minimum required height, though this does not affect vehicle safety or function.

What can fail
The rear reflex reflectors are mounted lower than the 380 mm minimum height required by Canadian regulations, reducing their visibility to other drivers.
What the fix does
No recall action. Manufacturing has been updated so all new vehicles have rear reflex reflectors mounted at the correct height.
