AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE
Jaguar Land Rover North America, LLC (Jaguar) is recalling certain model year 2016-2017 Jaguar XJ vehicles manufactured September 12, 2016, to October 26, 2016. The affected vehicles have a front passenger air bag inflator initiator that may fail to ignite during a crash, preventing the air bag from deploying.
ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL
Jaguar Land Rover North America, LLC (Jaguar) is recalling certain 2017-2018 Jaguar XF and F-Pace, 2016-2017 Jaguar XJ and 2018 Jaguar XE vehicles. The instrument cluster (IC) may intermittently go blank.
ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:BELTS AND ASSOCIATED PULLEYS
Jaguar Land Rover North America, LLC (Jaguar) is recalling certain 2019 Jaguar F-Pace, F-Type, and XJ vehicles equipped with V6 or V8 gasoline engines. The crankshaft pulley retaining bolt may have been improperly manufactured, possibly causing the crankshaft pulley bolt to fracture, potentially resulting in engine failure.
AIR BAGS
Jaguar Land Rover North America, LLC (Jaguar) is recalling certain model year 2015 Jaguar XJ vehicles manufactured July 2, 2014, to December 4, 2014. The affected vehicles may have an incorrect description of the operation of Occupant Sensor System (OSS) in the owner's manual. Since the manual does not correspond with the actual Air Bag Status Indicator Lamp, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection."
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS
Jaguar Land Rover North America (Jaguar) is recalling certain model year 2014-2015 Jaguar XJ vehicles manufactured February 6, 2014, to July 23, 2014. In the affected vehicles, the brake line junctions under the vehicle may leak brake fluid.

The 2007 Jaguar XJ has 14 known issues documented across 5,370+ owner reports. 5 issues are rated critical: Air Suspension Compressor Failure and Plastic Thermostat Housing and Water Pump Impeller Failure on the 4.2 AJ34 V8 and Underfloor and Rear Crossmember Brake Pipe Corrosion (Recall 09V144 / Jaguar J012) and Electronic Parking Brake Module Failure and Stuck-On Park Brake and 276DT 2.7 TDV6 Oil Pump Housing Fracture at the Tensioner Mount and Crankshaft Failure from Oil Starvation (X350 XJ Diesel). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Jaguar XJ issues range from $0 to $9,000, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Air Suspension Compressor Failure, typically costs $1,000-$3,000 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The Dunlop or Hitachi air suspension compressor on the XJ fails due to overwork from leaking air springs or aging valve blocks. The compressor runs continuously, overheats, and eventually burns out. This is one of the most common and expensive repairs on the XJ. Repairs typically run $1,000-$3,000. Severity: high.
The naturally aspirated and supercharged 4.2-litre AJ34 V8 in the X350/X358 carries an unusually large amount of load-bearing plastic in the cooling system. The thermostat housing is plastic and its internal support fractures, which lets coolant recirculate through the engine whi… Repairs typically run $600-$1,800. Severity: high.
An NVH pad fitted to the underfloor undertray of early X350 XJ sedans traps road salt and moisture against the steel brake pipes running under the floor and over the rear crossmember. The pipes corrode from the outside in and eventually lose mechanical integrity. Because the X350… Repairs typically run $0-$900. Severity: high.
The X350/X358 replaced the mechanical handbrake with an electric park brake driven by a module mounted in the boot, behind the right-hand trim panel ahead of the wheel arch. Two failure paths dominate. The module itself is in a location that sees moisture from the well-documented… Repairs typically run $300-$1,500. Severity: high.
The 2.7-litre twin-turbo TDV6 (Ford/PSA-derived 276DT) fitted to the 2005-2009 X350/X358 XJ diesel has two linked bottom-end weaknesses distinct from the later 3.0 306DT story. The oil pump housing has a thin section where the rear timing-belt tensioner mounts; it cracks under lo… Repairs typically run $4,000-$9,000. Severity: high.
The XJ suffers from cascading electrical faults caused by body control module (BCM) software glitches and CAN bus communication errors. Phantom warning lights, inoperative features, and intermittent failures across multiple systems are common, especially after battery disconnecti… Repairs typically run $200-$1,500. Severity: medium.
This page previously presented one 2004-2009 electronic-throttle-body failure pattern as established fact. The audited official material does not verify that broad cause or model-year scope. It does show a direct safety conflict: NHTSA manufacturer-communication record 10017595 i… Severity: medium.
The rear crankshaft main seal on AJ-V8 engines in the XJ develops a slow oil leak over time. The leak worsens as the seal hardens and the crankshaft seal surface develops minor wear grooves. Oil drips onto the transmission bellhousing and can contaminate the clutch on manual mode… Repairs typically run $800-$2,000. Severity: medium.
The 2004-2009 X350/X358 uses a saddle-shaped fuel tank straddling the driveshaft, with a lift pump on one side and a venturi jet pump transferring fuel from the other. When the jet pump or the lift pump module degrades, the engine side of the tank runs dry even though the gauge s… Repairs typically run $400-$1,500. Severity: medium.
X350/X358 cars leak water into the cabin and boot by two separate and frequently confused routes. In the boot, water runs down the boot aperture and gets behind the black plastic strips at each rear lamp cluster; the rear vent seals behind the rear bumper below the lamps also fai… Repairs typically run $150-$900. Severity: medium.
The X350/X358 uses aluminium front lower control arms with pressed-in rubber bushings that were not originally available as a separate service part. The rubber delaminates from its inner sleeve and the arm develops fore-aft play, producing a clunk over bumps and when the suspensi… Repairs typically run $400-$1,400. Severity: medium.
The X350's ZF 6HP26 six-speed automatic passes its transmission control module wiring through a plastic connector sleeve in the side of the case, and uses a plastic oil pan with an integrated filter. Both parts are heat-cycled by transmission fluid for their whole service life an… Repairs typically run $450-$1,200. Severity: medium.
The 2004-2009 X350/X358 XJ was Jaguar's first all-aluminium monocoque, yet it is notoriously prone to paint blistering. Steel particles from the panel presses trapped in the aluminium sheet before painting, plus galvanic action where dissimilar-metal fixings and trapped salt wate… Repairs typically run $500-$4,000. Severity: medium.
On the 2005-2009 X350 XJ 2.7 diesel the twin EGR valves and the plastic inlet 'Y-piece' clog with soot. A valve stuck open feeds carbon back into the intake, restricts airflow and triggers 'Restricted Performance' limp mode; a valve stuck or leaking oil has been linked by owners… Repairs typically run $400-$3,000. Severity: medium.
