Land Rover Velar 300 D Moto damage with 90000 KM.

February 2019 first admitted, warranty until February 2022 and now a motor damage (crankwell is fixed) in March 2023. now I bought the car with 18000 km used and got an additional warranty until 2024 or 100 000 km. since september 2022 I drove the car very little. in the end january I wanted to give the car into the inspection but I did not get an appointment at vover before april 2023. now the car on the autobahn at approx. 115 km speed has everything excluded The automatik could not be unlocked and therefore the adac had to use a sick to pick up. the workshop explained a motor damage which I can never believe. a car for € 95000, – can not get a motro damage with 6 cylinders after 4 years. I like to drive rank rover and that for many years. my wife has an evoque and I have a youngtimer XK 8 cabrio. although I have a warranty extension I have now referred to the fact that I am three months over the last inspection and the 10000 km below the guarantee limit do not apply. I buy an expensive car that only lasts 90000 km. I need a legal profi against landRover and against the “Real Garant Zürich”. who can help me here? mfg charles
