RRS 2016 autobiography, had it 14 months now, although it seems to live at the dealership while I drive around in a crappy entry level jag.

1) The fuel tank was replaced within the first two months;
2) The rear seats were replaced due to a quality control issue (leather not fitted correctly);
3) We have a reoccurring fault with an airbag light which resets itself but keeps returning;
4) We had a front leaking differential which was replaced;
5) We had part of the refitted fuel tank fixed due to loud squeaking that was coming from the car - turns out the refitted fuel tank wasn't fitted properly;
6) Our air conditioning system stinks of cat urine, despite the cause being confirmed as a fault, the changes and air conditioning service have not improved the smell at all and it isn't just limited to when it is first on now either;
7) When the car was with Land Rover for item 5), it was returned with light scratches on the rear passenger side door and the car has been back in a bad state interior wise on several occasions - mainly oily muck on the treat plates.

I love the car when it is working, but it has got to the point now where it is ridiculous, driving round in a 80k car that stinks of cat with an air light bag coming on every couple of weeks.

I'd never own one of these outside the warranty period. Have I just been unlucky, or is this par for the course on this car...

You are not unlucky as we have seen other posts like this on the forum, but then also you are not exactly receiving professional back-up from either the dealership or Land Rover.

Suggest that if you have a finance agreement on the car that you contact the finance company and ask them for guidance as well.

Regarding the AC, sounds like you need to get an independent ventilation/ air con/ refrigeration expert in to look over the car You need to tell the dealership that you are having an independent expert to look over the car's ventilation system and then you will present the bill to them as they are incapable of curio get the issue. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
