When I plug in the L2 or L1 charger (I've now tried both) it seems like it's failing at the handshake. The charger keeps clicking and the car keeps trying to establish a connection. It eventually stops but then starts trying to handshake again in a minute or two. It will occasionally get a green light on the dash and the horn chirp, but within about 30 seconds it stops charging and starts trying to handshake again.
It's a 2012 with 73k miles so I think my Voltec is over just based on age. The charge port seems like a likely culprit here, what do folks think? Replacing it seems quite easy to attempt myself and it's not an expensive part at least.
