I did not see such issue anywhere but my 2020 model 3 has been warning for CC_a022 every few minutes since power trunk retrofit by Tesla. Car is charging fine but kept the car awake 24 by 7 which causes battery drain by 15 miles per day... I scheduled a service and was told this issue is under review by Tesla and no solution yet. How long has this issue been going on? I would think this issue been raised up quite a bit but surprised that I did not see any discussion about it.
