Jaguar Land Rover filed this with NHTSA as a manufacturer communication dated Jun 13, 2025, received Jul 6, 2025, about the power train. It names 21 model years across Land Rover and Jaguar (2019–2025). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 21 model years this bulletin names have filed 785 complaints with NHTSA since 2015. 60 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.
I am reporting what I believe is a safety‑related defect involving the automatic transmission in my 2022 Land Rover Discovery Sport, VIN . Approximately five months after the factory warranty expired, at around 44,000 miles, the transmission began slipping unexpectedly, and the vehicle would not accelerate above roughly 25–35 mph.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jaguar Land Rover TUCC_JUN2025_28 a recall?
No. A manufacturer communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TUCC_JUN2025_28 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TUCC_JUN2025_28 cover?
The manufacturer filed it against 21 model years across 2 brands (Land Rover and Jaguar): 2024 Jaguar F-Pace, 2023 Jaguar F-Pace, 2022 Jaguar F-Pace, 2021 Jaguar F-Pace, 2025 Land Rover Defender, 2024 Land Rover Defender and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
