What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 80 complaints with NHTSA since 2015. 10 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The transfer case on my new 2025 LR Defender 130 went out at 5,000 miles. This unit distributes power to the axles. I was told that if I continue to drive it, it could seize up, possibly leading to a loss of control of the vehicle. Land Rover is aware that they installed a bad batch of transfer cases on their new vehicles.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.
