2012 Range Rover Supercharge - Known issues

Recommended Posts

Are there any known issues in 2012 Range Rover Supercharge model or any specific things or recalls to verify before buying one?

I'm considering few options and RR is on the top of that list, so just wanted to check from experts if it's a good buy for another 2 years or not?

And since 2012 was end of line for the L322 most if not all issues should have been resolved and most probably as LR usually do they add a lot of extras on the last year of production. They did that with the P38 but not sure about the L322
