The component that Failed was the transmission outline Spline due to lack of lubrication from the factory. This causes the component to fail over time due to corrosion. When this component fails it makes the whole driveline fail/slip. Can happen while making a turn with fast approaching vehicles coming at your through the opposite lane. Also makes the vehicles parking function fail. As the car will roll freely when the shift indicator is in the Park position. The problem has been diagnosed by a certified Mechanic There are no warning lamps, messages or symptoms when this problem happens. Everything is working fine and the next second it is failing.

Driving on the road, with absolutely no warning, the vehicle suddenly lost any control of the drivetrain. Vehicle was left coasting in traffic, and the engine would rev without any influence on moving the SUV. The mechanic identified it as a known problem where the output shaft of the transmission strips the input shaft of the transfer case due to excessive fretting corrosion caused by insufficient lubricant/protectant applied to the shafts at assembly. I also read about others experiencing the problem while driving in traffic (Range rover forum posts). This initially left me in the middle of moving traffic with no way to move out of the way of oncoming traffic, as it has left others that have described the same sudden failure on the internet. The only remedy offered at the dealership is to replace the entire transmission and entire transfer case at a cost in excess of $13,000.

When you shut the engine off and put the vehicle in park the vehicle will keep rolling and not come to a complete stop. To prevent this from happening you have to apply the parking brake. You may be on a city street, garage, parking lot etc... the transmission had to be replaced on a 2012 vehicle with 54812 miles. This original one owner vehicle has been maintained by the dealer and the dealer only. No outside mechanics have ever touched the vehicle. This was a safety defect that needed to be repaired because failure to correct the problem could have caused serious damage or possibly death in the event the vehicle rolled a way and hit something or worse hit someone. You don't ever expect to have to replace a transmission on a four year old vehicle especially to prevent a roll a way accident.
