I had not driven the vehicle for about a week. When I started it, there was a message on the dash about the hill descent malfunctioning. I put the vehicle in Reverse, and without pressing the accelerator, it was incredibly difficult to stop. Had I not been in my own driveway, this would have been very dangerous. I had the vehicle towed to a service center, and they confirmed that the auxiliary battery was not producing enough voltage and this caused the brakes to fail. After researching this online, I can see that it is a known design flaw experienced by many people, but it has not been resolved by Land Rover! If this battery had failed in a different scenario, I may have been unable to stop the vehicle with a crash resulting.
