Mine lasted 3 months. Seems a pretty common problem with the unit overheating and limiting charging ability (amber light, no blinking blue light). My dealer said EVSEs weren't a part of the vehicle and NOT covered under the warranty.
I'd recommend installing a NEMA 14-50 in your garage and purchasing a third party charger. I have the Wallbox Pulsar Plus and couldn't recommend it enough.
You don’t have to use the MME charger. You can get a 3rd party charger and it will have the correct connection for you.
Here is an example:
