2013 Help needed: EVSE/Charge Cable no longer covered under Voltec warranty?

12922 Views 37 Replies 18 Participants Last post by  RodSlinger
So my 110V charge cable/evse got the dreaded "won't disconnect from the charge port" problem and broke when I wrenched it out. This is a Gen1 2013. Apparently this part "used to be covered under the Voltec warranty," but now they have decided as of Jan 1, 2018, that it is covered under the bumper-to-bumper 3/36 instead. Can they do that? Change after the vehicle is in service what is covered under the warranty? Is the service manager/part manager at Weseloh Chevrolet in Carlsbad, CA misinformed? Should this only apply to new vehicles?

Any help would be appreciated as I'm trying to figure this out in real time...

I don't believe it's right to change the rules in the middle of the game such as this, but the EVSE warranty has been a huge topic of confusion with some dealers stating that yes it is part of the Voltec warranty since the EVSE specifically states "Voltec" on the device, and a vast majority of others stating it's only covered under the B2B warranty.

That said, I have not seen anything in my included books on the warranty coverage for my '13 that specifically put the EVSE into the Voltec warranty coverage. The B2B coverage pretty much covers everything, so denying coverage would need a d*** good excuse from GM, in this case however they could state it was a case of abuse and deny the coverage.

Finding a replacement EVSE can be done for about the same or less than what one would pay GM for an OEM replacement. On the other hand, if you only broke some of the plastic for the gun type plug that goes into the charge port on the car and your reasonably mechanical then you should be able to easily replace the J1772 plug. They're usually about $80 or so which makes them not exactly cheap. On the other hand, you can find an EVSE that can do both L1 and L2 for about $100-150 more. It's just a matter of plug type and input voltage since they're auto switching and take 120-240V.

The handle button does more than just release the clip holding it into the charge port. There is a micro-switch that gives a looping return signal to the vehicles charger indicating an EVSE has been connected and waiting for the handshaking signal to begin negotiating charging rate. When the handle button is in its rest position (not pressed to release/insert) it has a resistor inline between two of the pins on the EVSE handle. This is detected by the onboard charger that gives it the ok to negotiate charging rate and request power to the high voltage pins. When the handle button is pressed, a different value resistor is switched on which tells the car to stop charging so the pins carrying voltage go "dead", hence the clicking relay inside the EVSE you can hear shutting off power to the plug. If you just remove the EVSE handle without pressing the button you can get arcing inside the port which will greatly reduce the life of your charging port, EVSE handle or at worst, cause damage to either the EVSE or even the vehicles onboard charger. Definitely always use the handle switch when connecting or removing the plug.
