What it saysMisfire on new replacement or reman units â AJ126 NHTSA’s full summary ↓
Jaguar filed this with NHTSA as a service bulletin dated Apr 21, 2023, received May 3, 2023, about the engine. It names 15 model years (2017–2019). A service bulletin 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 15 model years this bulletin names have filed 175 complaints with NHTSA since 2015. 89 of them name Engine, 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.
On the 2017 Jaguar F-Pace, the 12 owners who gave an odometer reading for Engine reported it at a median of 75,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2018 Jaguar F-Pace. The contact stated that while receiving repairs on the engine, the dealer became aware of a crack on the rear differential. The vehicle was not repaired. The manufacturer was notified of the failure and declined to cover the costs for the repair. The failure mileage was approximately 126,000

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 SFCC_APR2023_34 a recall?
No. A service bulletin 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 SFCC_APR2023_34 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 SFCC_APR2023_34 cover?
The manufacturer filed it against 15 model years: 2019 Jaguar F-Pace, 2018 Jaguar F-Pace, 2017 Jaguar F-Pace, 2019 Jaguar F-Type, 2018 Jaguar F-Type, 2017 Jaguar F-Type and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
