You can get it fixed by replacing the clutch at a good independent. Perhaps it's your driving style?

You may find an auto electrician better bet; here's one I recommend, but only operates in Thames Valley

Having it serviced at Nissan also gives you 1 year of free breakdown cover, and you should get a map update, and the car's s/ware updated.

Charge it to Halfords.

Simples just increase the concentration; my Nissan screenwash at 1 to 1 dilution protects to minus 75deg C

If that fails, you'll probably find an auto electrician cheaper than Nissan; this is one I can recommend in
Thames Valley.

After 12 years, you probably need a new clutch.
