Just FYI.
" A couple weeks ago (Oct 2), I was DC fast charging my Mercedes EQS 450 at the Electrify America station at Sam’s Club in Murrieta, CA using the factory-included 2-year Mercedes me Charge plan. (For context, this car has only ever been charged on the official Mercedes home wallbox or EA via factory Plug & Charge—never any third-party adapters).
During the session, the plug welded itself solid inside my car’s charge port. An EA field tech came out, couldn't unlock it, and literally had to pull out tools and physically cut the charging cable off the station to free my car. While there, the tech taped off the dispenser, took the other two chargers down remotely, and told me plainly that the connector pins were burned and "needed to be replaced anyway," venting frustration with dispatch for delaying maintenance.
Then Mercedes Roadside Assistance sent multiple tow contractors who had no idea how to tow an EQS—none of them could figure out how to get the car into neutral with the high-voltage fault active and refused to take it. The local dealership (Mercedes-Benz of Temecula) had to privately hire their own tow operator on wheel dollies to move it.
The car has now been sitting on the dealer lot for over two weeks with ZERO progress:
• Electrify America (Case # 03448697 / 03454158) sent a denial email citing their "Terms of Use" to avoid paying for the melted inlet, and refuses to speak to the dealership.
• Mercedes-Benz (Case # 24855033) is refusing to touch it under warranty, claiming it’s an EA problem—even though EA is Mercedes' contracted charging partner.
I’m paying for a $100k+ car that's been dead for almost 3 weeks while two massive corporations point fingers at each other. EA's tech admitted the hardware was damaged beforehand, and Mercedes has a 30-day clock under California Lemon Law (Song-Beverly)."
 
That is wild. I tend to stick to Tesla due to stories like this. It isn’t always the fastest, but it’s reliable and proven.

Since getting the Gravity, I haven't tried EA and was thinking of giving it another shot but this story really gives me pause.
 
Seems like, outside of the reliability of Tesla chargers, that Ionna is the one that is really impressing people.
 
2 things that can cause port welding. Overtemp in the pins during charging which is absolutely measured by the car and likely measured by the charger, but it really should’ve been the cars job to end the session. The other is if somehow you were able to pull the gun in the middle of a session during the charge which could cause arc welding, doesn’t look like what happened here but also the cars job to keep the port locked. Regardless, I don’t think it’s the charger at fault here.
 
The above is to say that while some issue or standing damage to the charger could have been the source of the actual heat generation, cars are built to anticipate this on both the AC and DC side and monitor individual temps to prevent this. So I still don’t blame the charger.
