Just wanted to update from my thread below about not being able to unplug my car from the Mustart level 2 charger. I had the car hauled to my dealer with the cord still plugged in since it was covered under roadside assistance and the car still has warranty. They were able to pull the charger plug out without breaking anything. The port and plug was not as bad as I was expecting. I have attached some pictures of the port and the plug. Basically, the upper right pin on the car port got too hot at some point. It appears black in the pictures where the others are still brass colored. Not sure how much of the pin is black/corroded. The black on the tip may just be plastic melted. You can see the corresponding socket on the charger plug is also black/corroded. GM, as expected , says the car port needs replaced @about $1300 installed. GM, as expected again, will not warranty the port because it was an aftermarket charger. The dealer is waiting for GM to release which dealer has the part in stock and will release to my dealer. They recommend not charging the car any more until they can evaluate if there is any damage to the wiring behind the charging port. I had my dealer print out what has been done and what needs to be done to gather information to send to Mustart to see if I can get them to pay for the damage to my car. My phone call to Mustart went to voicemail. I will leave a message and email them the photos and information I have from my dealer after they see if there is any more damage behind the port on the car. I asked my dealer what level 2 charger is approved for the Bolt. They only had 1 to choose from and it was a hard wired one. They are currently checking to see if there are any other approved chargers the plug into my wall outlet. I am not expecting any help from Mustart, but maybe I will be surprised. They have a problem with these older chargers and need to get them out of circulation asap. In the first picture below the damaged connector on the charger plug is the upper left one. In the second picture of the car port, the damaged pin is the upper right one.

I am sorry you had this much of a trouble.
I would suggest to check ClipperCreek site and chose a L2 EVSE that fits your need. I have mine (LCS-20) for already 8 years now and I never had a problem with it. The service and support is also great. When I decided to buy from them, I called them and they were very professionals.

ClipperCreek was recently sold so I hope at least some of the great group of people are still there. Here's the info on their site:

I can't really see the extent of the damage to the car's pin but you might be OK charging with the 120V included charger until you can get it fixed. That's if the damaged pin is mostly just discolored and not loose or eaten away in diameter.

Just replace the parts that are bad. You don't need a whole new EVSE, just the J1772 handle. One with good quality pin grip.


I already replaced the handle on my Mustart 32A EVSE for this exact problem- excessive heat on the pins in the charge port.

I replaced the handle on my EVSE because the trigger broke. I would not classify replacing the handle as an easy DIY job. I ended up leaving the pins from the old connection because I did not have a crimper to properly re-crimp the pins and in the case of the Mustart I think the Pins are part of the problem. A handle costs about $100 and about 1 hour worth of time. If I was doing it over again I would have just bought a new EVSE rather than just replacing the handle. Or I would have fixed the one I had.

I agree that you should go after Mustart first, but failing that, @Kbecker 's suggestion about a possible auto insurance claim is also a good thing to check. It might even be worth finding out if your homeowner's insurance would cover the damage, since the incident occurred in your home. (Although it might not be worth filing a homeowner's insurance claim.)

I disagree that the only thing to repair is the Mustart handle, and I personally wouldn't try charging Level 1 or Level 2 until the wiring behind the charge port has been checked out. The damage doesn't look bad, but it might not be the only damage.

I specifically asked my dealer about level 2 chargers and the GM warranty my car is still under. No aftermarket chargers are approved by GM for the Bolt. The only one that will keep your warranty in tact is the one you buy through them. I know that charger is also "aftermarket" but it is approved by them. So, it doesn't matter which level 2 charger I buy to replace the Mustart, whether it be a Clipper Creek or other, it will be the same story if damage is done to the car charging port or other charger wiring. The GM warrant will not cover it.

I have no experience with Mustart, and I'm not giving them a free pass. But I'd comment that (Americans, especially) have a background of a very sloppy/tolerant experience inserting and removing 5-15 household plugs. Back before required grounding, you could hold the plug even more diagonally to insert and remove it. It can't help that the J1772 has such long pins and such imbalance between the weight of the cable and the open end of the plug. Unless you approach plugging in your EV with a little more .... methodical procedure ... it's not going to help extend the life of these components. If you used to work in a factory, or at NASA, or even RV's, you would not approach the connection as a casual affair. Not criticizing, just commenting.

It sure doesn’t cover it and I didn’t imply it would. But, my suggestion for you was to go with an EVSE maker that has a proven, reliable product for already more than 15 years. There were not many when I bought my EVSE in 2014. And ClipperCreek (Sun Country) were the best at the time, money wise investment and reliable.

Is the Mustart unit UL approved? If so, then Chevy can't tell you it is unsafe to use for charging of your car and deny the warranty repair. If they want to sue Mustart for the damages that is their business. If the Mustart unit is NOT UL approved then it becomes much harder.

GM and dealerships tell customers to pound sand all the time. Even if it’s UL listed that doesn’t gaurentee that singular unit isn’t defective.

If I recall another forum member recently got mustart to pay for similar damages. I think there was a mustart customer service rep quasi-spamming the thread with apologies and claims about a bad batch of EVSEs.

Except GM's warranty is supposed to cover defects with the Bolt, not defects with 3rd party equipment. If something else in my garage catches fire and damages my Bolt, GM wouldn't cover Bolt repairs under warranty.

OP would have to show that the damage came from a defect in the Bolt, not in the Mustart EVSE, for GM's warranty to apply. It doesn't matter how the equipment is rated - what matters is which unit is the source of the damage.

If the cause of the damage is the Mustart EVSE, GM has no responsibility in this. Unless you tell me that if I am hit by lightning on your driveway, I am entitled to ask you to pay all my health bills incurred by this incident. Because hey, it happened on your driveway !

Question - did you have the 1st Mustart version known to have overheating issues or the 2nd version? I bought the newer version after reading reports about the problems that existed with the old style. The newer one has a nice all metal handle and we've never had a problem in the 1-1/2 years we've owned our Bolt. I'm concerned if your issue was with the new style.
This is a new issue that we have to deal with EVs. In the ICE days, there are multiple ways to mess up your car and engine that wouldn't be covered. It will be a learning curve for us until the dust settles on the best products.
