Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability

The T1XX platform delivers unmatched chassis stiffness, enhanced towing capacities, and sophisticated camera-based trailering aids.
The new 6.6-litre L8T petrol V8 provides robust, dependable torque without the maintenance complexities of diesel emissions equipment.
The Duramax L5P paired with the Allison 10-speed transmission provides peerless towing torque and exceptional motorway hill-climbing refinement.

Chronic weak spots

Keep an eye on

6.6-litre L8T petrol V8: check engine oil level regularly during heavy towing, inspect exhaust manifold studs, and monitor cooling efficiency.
Duramax L5P and Allison 10-speed: check transmission software calibration records, inspect fluid temperature, and verify smooth low-speed shifts.
DEF/SCR emissions system: inspect the urea dosing injector, check NOx sensors, and ensure the diesel is not operated exclusively on short runs.
Front running gear: examine torsion bar suspension arms, heavy-duty ball joints, and steering geometry on trucks pulling maximum tongue weights.
Trailering tech and load bed: test the transparent trailer camera system, 7-pin trailer wiring plug, and inspect fifth-wheel bed mounts.

Critical deadlines

Do not miss

DEF, SCR, or NOx sensor trouble codes on the Duramax L5P must be resolved promptly to prevent the vehicle entering a restricted speed mode.
Transmission, transfer case, and axle lubricant changes remain mandatory service intervals on trucks engaged in regular heavy haulage.
On L8T petrol models, any engine overheating or exhaust manifold ticking must be rectified before embarking on long towing journeys.
Worn suspension ball joints, loose steering linkages, or damaged trailer camera wiring must be rectified before towing heavy plant.
