I recently ran into an issue with my charger malfunctioning and needed to be replaced. The car basically would not charge when I got it home. Symptoms looked like the little box on the charge cable would click on and off 4 times before the charge port would glow red. You could see the voltage rising up to 240 when the cable clicked on, then go back to 0 when the cable clicked off. Anyway, the car was flatbed back to Tesla service.
Then I was hit with the issue. The charger needed to be replaced. The thing that blew my mind was that the warranty on the charger expired at 50000 miles, while most other parts in the car expire at 80000. I had just hit 55000 when this happened and I didn't think I would have to foot the bill, which turned out to be $2300, parts and labor.
I don't know whether anyone else has had experience with Tesla warranty replacements of the charger. I found this to be very unreasonable extremely costly. I have had a number of issues with the drive unit (1 replaced under warranty) and I am detecting that the replacement is malfunctioning also. Needless to say, not happy about the warranty program and not looking forward to a drive unit replacement if, nay when it fails again.
