Tonight I called Landrover Assist. I pulled up to pick up my daughter, I put it in park. The car auto shut off. When I started up again the gear selector was locked in Park and the dash said "Gearbox Fault" it also had a series of about 3 other messages about stability control and other things not being available. I turned the car off and on about 3 times with no change. LR assist therefore despatched an engineer. I waited about 5 mins with the engine off, then restarted and this time no warning messages and I could select D.

I'm now very worried that the car is going to breakdown at some other point and leave my wife and children stranded.

Has anyone else experienced this issue? What was the solution?

Thanks

Lots had this issue and it was a replacement rotary switch pack unfortunately... If you don't have a warranty then approach JLR, they may help as its a known issue

Thanks, do you have any more information on the rotary pack fix (sorry I couldn't find anything searching the terms)? BTW the car is 2014 3.0SE.

I got the Gearbox Fault on my P400e. It was freezing conditions and I had been running the remote heat for 30 mins, had previously done some short journeys the previous day, and so the battery voltage had dropped very low. The engine would start normally but Drive could not be selected. I ran the engine for a while, turned it off, locked it, waited a few mins and then restarted to find all was fine.

Searching for gearbox fault in this forum took me to a thread about battery levels and stopped me lurching for the Land Rover Assist option. Good stuff, so great to have this forum.
