I took delivery last summer of a one-year-old Land Rover Discovery 4. The turbos have repeatedly failed and been replaced by Land Rover, most recently for the fourth time. Land Rover modified the pipe from the turbo to the oil sump and returned the car to me. I wanted to reject the car and asked the dealer to replace it. He said he would and also that he would get help from Land Rover.

Three weeks later he has not returned six calls from me and I appear to be have been misled. I feel very sad about the whole affair as I have bought four cars from this dealer, spent £150k with them in thirteen years and I am being treated poorly. Do I have any rights to return the car? What advice would you give me?
