2022 Model S Long Range. Since the car has been delivered, I've intermittently been seeing some charging errors when charging with my Gen 1 wall charger at 40a (on a 50a circuit). This wall charger was installed by a Tesla-certified/recommended electrician, and worked flawlessly for 3 years with my Model 3, and has charged other Teslas without error. I'm confident it didn't suddenly fail on the day I took delivery of the new car.
This morning I noticed the car failed to charge overnight -- and was still down below 50% this morning. I re-seated the connector several times, to try to get the car to take a charge. After several attempts, it worked.
Grabbed a snapshot of the errors (apologies for moire pattern):
Right. Service request submitted. Next opening is a month out (sigh), so I'm going to cotact them to get in sooner, since this is a car reliability issue.
Finally, I did a little checking in other vehicle forums. Looks like some folks with recent (Q4 2021) builds had similar problems with home/AC charging, and needed an ECU swap. Will keep updating as this progresses.
