Hi All, looking for a bit of advice on here. my 2010 3.0 V6 luxury XF has just ran out of warranty on the 9th March. since December last year it has had two new sets of rear discs and 1 set of front discs replaced under the warranty as they were warped. I 'm sad to say that I have severe juddering again under braking even though I had asked Stratstone Jaguar to check out the braking system fully whilst in for it's 3 year service a few weeks before the warranty ran out. the car has only got 29400 miles on it! I'm starting to lose the faith in the quality of the vehicle as to top it off it also drops into "restricted performance" mode randomly which resets itself after the car has been parked up for a few minutes and then will be fine for a few days then it kicks in again. has anyone else had these issues and what course of action do you recommend?
