NHTSA Complaint #11495871 — 2008 LAND ROVER LR2

I have a 2008 Land Rover LR2 in mint condition and regularly maintained by a Land Rover dealer and purchased new from a LR dealer in Pittsburgh. It only has 39K miles and always parked indoors. Last year I noticed a humming, grinding sound coming from the rear wheels.I took it twice to the Fort Myers Florida LR dealer for service but they could not find the problem other than that the differential needed flushing (unusual for 39K miles). Finally took it to LR dealer two weeks ago in Naples, Florida and it was determined that the rear differential needed replacement. It was explained to me by the Asst. Service Mgr. that it was not safe to drive as the wheels could seize and cause an accident. No warning lamps indicated the problem. Land Rover refused to pay for replacement ($10K quoted cost) citing 4 year warranty period was over despite way below 50K mile warranty. Discovered over 30 similar problems reported on LR2 model on "carcomplaints.com".
