I had the 110v wall charger for a Chevy Volt that came with the car. To be fair, I bought the car certified pre-owned, so I guess it was about 5 years old when it broke. I left it outside in inclement weather 24/7. I’m not sure if it was covered under warranty. What broke were the connections inside of the plug handle. I took it apart and soldered it back together. That lasted another six months, and then it broke again. I traded the car in after that, so I never tried to file a warranty claim or anything, but I don’t think it was covered. I didn’t trade the car in because of the charger though. I just happened to find the exact used truck I wanted, in the exact color I wanted, right about when the charger broke, so it worked out.
Edit: I just wanted to add that I loved that car! It was a great car. Literally the only thing I didn’t like about it is that there was no knob to change the AC temp. You had to hold your finger on the touch button and wait like 30 seconds while it slowly adjusted. Everything else about the car was great. One of my favorite features was the little button on the end of the blinker indicator that gave 3 quick polite little horn beeps. I used that all the time to alert people that they were in my way, where a full-fledged horn honk would seem rude.
