2025 Ineos Grenadier Recalls, Issues & Maintenance
The 2025 Ineos Grenadier has no open NHTSA recalls. No recurring owner-reported issue clusters are on file. The Grenadier pairs a BMW B58 straight-six with a schedule written for actual work: service every 12 months or 12,000 miles, and Ineos itself says to halve that under sustained off-road use, towing, or wading. That honesty is rare and worth taking seriously; water crossings age axle and transfer fluids no matter what the calendar says. Brake fluid goes every 2 years. The driveline runs published multi-year fluid cycles, with sources disagreeing on the axle interval, so confirm yours against the service booklet. A 5-year unlimited-mileage warranty backs it. BMW norms cover the engine internals; the truck bits are pure Ineos.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Essential maintenance
Critical for safety and preventing major damage
Oil Service (Annual)
Every 12,000 miEvery 12 months or 12,000 miles with BMW-spec synthetic; every 6 months or 6,000 under heavy off-road, towing, or wading duty, per Ineos's own guidance.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Annual Service Inspection
Every 12,000 miUnderbody, driveline seals, and breathers inspected annually, immediately after any deep-water work. This truck is designed to ford; the schedule assumes you will check what the water touched.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free with any paid service. A flashlight and 10 minutes covers the basics yourself.
Brake Fluid
Every 24,000 miEvery 2 years regardless of mileage.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Tire Rotation
Every 6,000 miRotate with each service or sooner; heavy all-terrains on solid axles reward frequent rotation.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Important maintenance
Keeps your vehicle running smoothly and efficiently
Axle (Differential) Oil
Every 48,000 miPublished guidance conflicts: one source says inspect at 2 years and replace at 4, another documents a first-service change then a long cycle. Confirm against your service booklet, and change early after sustained wading regardless.
Estimated cost — typical U.S. ranges
Dealer
~$150–$195
Shop
~$105–$135
DIY
~$20–$50
Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.
Transmission & Transfer Case Fluid
Every 72,000 miThe ZF 8-speed and transfer case run roughly a 6-year published cycle here, notable because the same ZF box is called a lifetime fill in BMWs. Off-road duty shortens it.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

~$285–$330
