My new discovery sport is 3 months old, NAV system would not store HOME, or any saved destination. I never knew one moment to the next when the NAV system would be functioning. Sometimes the data was there, more often than not it would not be. I have been dealing with this since buying the Sport model for tree months with the Princeton dealership who basically cannot do anything about the issue. They said they were waiting for a patch from the big boys in England. My vehicle was in service for a month with absolutely no progress. They now want me to bring back the loaner, and use the defective vehicle until a patch can be formulated. I am exhausted from dealing with this on a daily basis. I want my money back, my contract torn up, or a new model without any issues. Land Rover knew of NAV issues before I purchased in some of their Discovery Sport models, but I was not told anything! I have filed for Lemon status in NJ and am awaiting a date for a court hearing. I would not buy from Land Rover again-- their business decisions are obviously to make me wait for an unknown amount of time, while paying for a new vehicle is stupid and cheap!Wow that sounds scary. Hopefully it's just the matter of bad battery. What state are you in just curious. And do you have the launch edition given you've had it since February which is the earliest I've ever heard someone had the car.
