2023 INEOS Grenadier Quartermaster

Like other Grenadier models, early Quartermaster double-cab pickups manufactured during 2023 and early 2024 were recalled due to defective exterior door handle buttons. Insufficient internal grease application causes the heavy-duty push-button to seize in the depressed position when pressed. If the door is subsequently swung shut, the internal latch fails to engage the B-pillar or C-pillar striker pin, allowing the heavy passenger doors to unlatch and swing open while negotiating corners or traversing uneven off-road terrain.

Symptoms: Exterior door release button remains stuck flush inside the handle bezel after opening, Door bounces back open or fails to catch on the striker plate when pushed shut...

The Quartermaster's 305mm wheelbase stretch and substantial 545mm rear body extension reduce its off-road departure angle from 36.1 degrees (on the Station Wagon) down to 22.6 degrees. When descending steep quarry drop-offs, navigating deep drainage gullies, or reversing over high kerbs, the heavy-duty towbar framework, chassis rear crossmember, and bumper corners frequently ground out. Severe impacts can bend the rear bumper mounting brackets, distort the drop-plate hitch, or crush the 13-pin trailer electrical socket.

Symptoms: Scraped metal, flaked paint, and bent steel brackets on the underside of the rear bumper corners, Trailer electrical socket cracked or failing to supply power to connected trailer lighting boards...

With its extended 3,227mm wheelbase, early Quartermaster pickups (2023–2024) suffer from an enormous 14.5-metre turning circle. Navigating tight UK petrol forecourts, mini-roundabouts, or multi-storey car parks requires intense hand-over-hand wheel cranking. Combined with the recirculating-ball steering box's reluctance to self-centre, drivers experience significant arm fatigue on winding rural roads. In 2025, INEOS fitted revised steering bump-stops and a variable-ratio Bosch steering box that reduced the turning circle to 13.8 metres and improved self-centring.

Symptoms: Extremely wide turning radius requiring three-point turns in standard UK road junctions and parking bays, Driver must actively unwind the steering wheel back to centre when exiting tight roundabouts...

Est. repair cost: £350–£1,100

The Quartermaster features a heavy-duty drop-down tailgate engineered to withstand a 225kg static load. However, repeated heavy loading—such as rolling heavy plant machinery, timber balks, or fully laden Euro pallets over the tailgate—places tremendous shear stress on the two lower hinge pivot pins and braided steel support cables. Over time, the tailgate can sag out of alignment. Furthermore, when fitted with an aftermarket or optional tonneau cover, water frequently seeps past the bed front bulkhead seals during heavy UK downpours.

Symptoms: Tailgate catches or scrapes against the rear bed pillars when lifting it into the closed position, Noticeable vertical play or looseness in the lower tailgate hinge brackets when the gate is partially lowered...
