Hi Ginpen7, in the UK Nissan will support the vehicle. Meaning you can get it serviced at an Infiniti supported Nissan dealer. I am in Cornwall and I have JFE Nissan in Exeter who Infiniti have approved and trained the technicians to work on our vehicles - so the three year warranty is valid. Like MotoPete explained ATS and Quickfit or your local garage can get you service parts as mechanically these cars are Mercedes GLA 2014-2018. I haven't tried ordering any specific Infiniti parts yet but I am confident with the correct Infiniti parts numbers my local Nissan garage can order them for me. You can get the correct parts numbers from the internet and the American Infiniti dealers webpages.
