It's hardly surprising Jag forums are a bit poop, your average owner probably doesn't have much 3G coverage in the golf club car park.
I can't see those faults being anywhere near bad enough to reject a car. My last GTI's tailgate very slightly rubbed the top of the rear bumper and although it annoyed me a bit I didn't even think it warranted the hassle of taking it to the dealership never mind rejecting the car.
Maybe as its a lease car your jag came through a different channel at the dealership than a privately bought one might. My colleague's jag (he's had a succession of them, and yes, he lives and dies on the golf course) was pretty faultless on delivery but was a retail purchase.
Some of the comments on "the other forum" are pretty typical of that place and the mentality of some R drivers but surely you have to give the dealership chance to rectify these things first?
Yes it's a £40k car but it's still mass produced and British to boot so I'd not expect German build quality.
But you'd expect the dealership selling supposedly prestige cars to PDI them properly in regards to the boot. Electrical issues are just a sign of the times with cheap throwaway electronics bought en masse by manufacturers.
Once they've had a few goes at fixing the faults then maybe it's a different story - possibly more a sign of a bad dealership than a duff car if it gets to that stage.
At least it's just fixable things, not major paint mismatches or wonky panels.
Still hugely annoying and disappointing, don't get me wrong. I'd be really peed off with the car too.
Or maybe, as ever, R400 has it just right!
