Hi Peter. I have had my 2007 2.7 for nearly three years now, and the handbrake has gone faulty three times. Twice due to low battery voltage (I had various electical items on for a long period without the engine running once, and trying to jump start another car whilst my engine was just ticking over).And once when the battery was disconnected for several days while I had the engine re-conditioned! At 98,000 miles the crankshaft broke! Along with the new crankshaft I had a £4,000 + bill.I was not happy, but if I hadn't had it repaired it would have been scrap. Anyway,If the battery voltage drops by around two volts, this problem will occur. It is possible that the cold weather affects your battery if it is a little weak, or you have to turn it over more than usual to start it. The first two times I had the problem I took it to a Jag specialist and he re-programmed the ecu, but the third time, I learnt the trick explained elsewhere on this forum and that worked very well for me (and a lot cheaper than the Jag guy!). Keep your battery voltage up and you should be ok. Good luck!

Hi Richard. This looks like an old post now, but just in case you still arenot sure about your park brake, when you exit the car and press the key fob you should be able to see the brake warning light come on from outside the vehicle (the red one). If you don't see it, then I would suggest it is not on. It stays on for a few seconds so should give you time to check.
