Im having the same problem, and let me tell you it gets worse. Initially I was getting warning messages on the range rover sport constantly, transmission fault, special programs off, hdc fault, so many of them now, I cannot even remember. Then I started getting the problem with the ignition. I have had EVERYTHING replaced. battery, transmission, alternator, etc etc etc. Initially the dealer I purchased the vehicle from was covering these repairs, now he is saying the warranty is up, so its my problem, which infuriates me, as I have basically had these problems since week one. Just so you are aware, now the vehicle does not start up, most cold mornings. It will not work on jump leads, unless from another range rover, or similar powerful vehicle, or from a self contained battery charger. So you will definitely be stranded. I am now having to fork out for a tow truck each time this problem occurs. I cant get it started at all. There is a message on the radio screen, saying low power mode. I have had almost every expert in ireland look at this for me. No one has a notion what is wrong or how to fix it. do we not have some sort of comeback, even with Land rover. I feel like we have been stiffed with faulty vehicles. Is there anyone out there who can advise me on this. I was also told, that the subwoofer on the radio could be running the battery down. Or that It could be my hands free kit in the vehicle, or the fact that I got 22inch rims put on. All these sound like ridiculous reasons for a vehicle to act up like this. I have sent it in for repairs diagnostics etc, 20 times in the last 6-7 months, and now im stuck with this. Wish someone would help me, this is upsetting me, bankrupting me, and nearly losing me my job, as Im a rep, and there is a recession on, no one is safe. Please can someone help me. I have no where else to turn at this stage.
