Lease car not fit for purpose

Herzlos

If you're still in posession of and using the car, what are they investigating?

Are you getting a replacement car whilst yours is in for work?

Have you asked the lease company if you can get a replacement car?

How long have you had the lease? With 3 years to go and 3 months of work is it 9 months into a 4 year contract?

Nothing you can do to speed the process with FOS.

How old was the car when the issue happened?

As any rejection of the car, would be with the dealer that supplied it.
