I purchased a 2000 S Type Jaguar and before the warranty had expired the window regulators,starting with my driver side window,started going out. I have since had to replace each regulator cable and am now half way round again. The drivers side cable goes out most often and this is mainly due to its more frequent use. On average my cables have lasted about 2 years. I have had them replaced by Jaguar and other licensed mechanics. P.S. I'm thinking about learning to replace them myself but a recall is only fair, and long past due.
In 2004 in extreme cold weather the front driver's side regulator came off track and the window shattered.
Around 2009 the same thing happened to front passenger window. About $350 each time

Right rear window regulator went out. It has plastic parts and they dont last the life of the vehicle. This is not a easy job to fix either, the piece that holds the window to the regulator has to be used again and is very hard to remove, very frustrating.
ih ave one window that actually works. anyone have 411 on less costly regulators
