OEM 120v charger plug fused to extension cord

[Beachmason]

I left my charger plugged into an extension cord for 6 months and yesterday tried to pull the plug out and it was completely stuck. When I pulled extremely hard, the charger plug simply came apart and one of the prongs (not ground) stayed in the extension cord, destroying the charger plug! Car only has 10K on it, would a replacement be covered and/or can I simply have a new plug put on the charger cord?

While BMW might consider it a warranty claim, they have every right to ignore it. The manual specifically says to not use an extension cord with the thing, and as you found out, for good reason. Now, if the extension cord was a high quality one, not excessively long, it might have survived. Consider this: you can solder with a 10W soldering iron...the EVSE is pulling nearly 1500W, so if the quality of the extension cord is not great, a little resistance can create a huge amount of heat, which is probably what fused the thing together. You're lucky it didn't start a fire.

You could just install a quality replacement plug on the end of the wire, and it will probably continue to work.
