I just had a quick question I wonder if anyone had an answer to. Last winter on a exceptionally cold night I had difficulties with the car operating and it wouldn't run. I took it to the dealer and they told me it was because of the cold weather and a low voltage had triggered a fault. It ran fine after this. I'm now notice when the weather has gotten cold again down to about 30* Fahrenheit the engine seems to turn on and off quite frequently ( not spirited driving) as I'm driving it and I'm wondering if this is normal or if this is possibly due to a faulty 12v battery? if it's due to a crap battery what group battery do I replace it with? is it a 51r? 2018 touring clarity Thanks
