Should I take out a Lexus Extended Warranty?

I've been advised to replace a weeping water pump on my Lexus RX 450h at under 60,000 miles and less than six years old (an eye watering bill of £1800 reduced to £1200). Should I take out a Lexus Extended Warranty (£995 for two years) as insurance for any other possibly expensive failures?
They are generally reliable, very few complaints, but air suspension relies on airbags and they have a limited life.
