Hello all! New to forums but I've been trolling the past few weeks doing my research on the '09 XK convertible I just purchased. So far I love it!!

One perplexing issue I've encountered is an audible "low battery" warning I've received twice in the past few days. No visual dash warnings or lights come on, just the audible warning. The Porsche dealer I bought the car from (trade in) is installing a new battery this weekend so hopefully the little voice goes away. I also bought a CTEK MXS 5.0 to hook up in the trunk for everyday maintenance of the battery. I've used a tender on my 2016 Harley Street Glide and swear by them.

My concern is that neither my local Jag service department nor Jag of North America ever heard of this car having an audible warning for a low battery. They only know about visual dash warnings (aka dummy lights). Jag NA said they'd look into it but I'm not holding my breath. Nothing online or on this forum that I could find either. And if it is a low car battery then why am I not receiving any dash warnings or lights? There's nothing extra hooked up to this car, aftermarket or otherwise.

Anyone ever hear of this? I changed the key fob battery the other night as a precaution and haven't driven the car yet. However, I don't think that was the issue as the key seemed to be working fine. Would love to hear your thoughts. Thanks!!

 

Sorry, can’t help with the “voices”, but congratulations on your first Jag. That is a beautiful XK. Good luck with it.

I also just bought an 09 XK Coupe, on October 20. It is also my first Jaguar, so hoping it’s as reliable as my past sports cars, Miata, RX-7 and a 240-Z.
