Quick update.
Got the car back after 12 weeks waiting for a battery control module. Had it back six days before problem re-occurred whilst I was 350 miles from home on business. Hyundai assistance phoned me 23 times during a five day recovery mostly asking me where they keys were. They seemed unable to understand that it was an unaccompanied recovery. . Last call was to ask me where the keys where. The car had gone from York to Nottingham to Trowell services on the M1 to Taunton Services on the M5 then arrived at my local dealers on a Sunday. Now apparently it is a different control module that has gone. So, Hyundai have stripped a new module off a brand new car somewhere and it is supposedly getting fitted today. I don't hope out much hope for it as there is obviously a root cause that hasn't been addressed. Wouldn't touch Hyundai again.
Got the car back. Apparently, it is a problem of it not waking up from deep sleep mode. So, new advice from the dealer is to open the door manually by flipping the key cover off the handle then using the key. Apparently, the car should wake up. Note the should. Well, that sounds like Hyundai dealer and technical haven't a clue. After 15 weeks off the road it's time in say goodbye. Interesting aside is that the service manager runs a 15 plate diesel Kia. He said he wouldn't touch a PHEV or hybrid with a barge pole.
