My five week old 2021 Corsair GT PHEV has less than 700 miles on it mostly from taking it to the dealer over and over. When we received the car it would charge to between 30 and 36 miles (100% charge) using the Lincoln 120 VAC Level 1 charger. The official Lincoln published number is 28 miles for a 100% charge. I could not try the Level 2 Lincoln charger because I has no 6-20R socket. I had a certified electrician put in a 14-50R socket and 240 VAC wiring for use with a 3rd party Level 2 charger. The Lincoln Level 1 charger suddenly began to pop the GCFI socket it was plugged in to and the charger stopped working. It has fried the 120 VAC socket. The dealer replaced the unit, I replaced the GCFI. I have had three 3rd party Level 2 chargers (two Grizzl-e and one emporia, all returned via RMA), none would charge the car. I had the same electrician check his wiring twice to find that 240 VAC is at the socket. I bought a 18" long 14-50P to 6-20R cable to try the Lincoln Level 2 charger without having to replace the 14-50R socket. The Lincoln Level 2 charger works off and on now and charged the car to 26 miles for two days but today it charged to 22 miles for 100% charge. The high-voltage battery and/or the high-voltage charger onboard the car seem to be slowly dying. The dealer insists it is my wiring (now checked three times), all three of the 3rd party charger(s) from two manufacturers, the 14-50P to 6-20R conversion cable their Service Dept recommended; you name it but not the car. They are now talking about sending over their electrician to be sure mine was not a simpleton (I may have to pay him) and/or another plug in Ford/Lincoln to try the charger. This is suppose to be a high quality, luxury, $65K Lincoln. I had never spent that kind of money on a car before but I am 76 and wanted to own a luxury car as one of my last cars. Instead I have received nothing but grief and aggravation from this car and my dealership. Is anyone on this blog having a similar issue? Does anyone have an idea of what could be wrong except the car? Thanks for any help!!!!
