I know this sounds trivial, but every morning in NY where it was mostly 20's when I would first start the car in the morning, when going to crank it the steering column or dash makes a rewally weird electrical frinding noise of some sort and resets ONLY the trip meter for A and B. It sounds petty but its irritating!

 

Just as an update, this was the ORIGINAL jaguar battery in this car at 68k miles. It was very, very dead. A new 740cca battery has cured this from every happening again.
