Here's from Tesla's notice "
NEMA 14-30, 10-30, 6-50 Adapter Recall" (thank you MP3Mike for the link):
How to determine if your adapter is affected by the recall
Your adapter will likely be included in the recall if you purchased it more than six months ago. To check, compare the part number on the prong side of the adapter to the table below. If you find a match, your adapter will be replaced.
Recalled Adapter, Part Number
---------------------------, ---------------------
NEMA 6-50, 1016021-00-A
NEMA 6-50, 1016021-00-B
NEMA 10-30, 1016174-00-B
NEMA 14-30, 1018243-00-A
NEMA 14-30, 1018243-00-B
The latest version of the NEMA 14-30 adapter does not need to be replaced. They have part number 1018243-00-C and have a gray plastic cap (on the right in the photo), rather than a black plastic cap (on the left in the photo).
Are any of the standard equipment adapters affected?
No, only 14-30, 10-30 or 6-50 accessory adapters purchased separately are impacted by this recall. The 14-50 and 5-15 adapters included with your Tesla are not affected.
