5.7L HEMI V8 (Multi-Displacement System)
Petrol
Listen carefully near the front wheel arches during a cold start for a rhythmic ticking sound. In these HEMI engines, it is common to consider the possibility of exhaust manifold bolts stretching or snapping over time, which may lead to a minor exhaust leak that often disappears once the engine warms up.
While cruising at a steady speed on a flat road, pay attention to the transition between 4-cylinder and 8-cylinder modes (MDS). If you notice a noticeable shudder or hesitant vibration, you might eventually need to budget for an inspection of the lifters or the Multi-Displacement System components.
Cycle the air suspension through its various height settings, from 'Entry/Exit' to 'Off-Road 2'. Depending on the car's history, the air compressor or the air bags may eventually need attention if the vehicle struggles to reach the desired height or if the pump runs excessively.
Spend time interacting with the 12-inch Uconnect touchscreen, checking for 'ghost touches' or screen delamination (looks like bubbles under the glass). In cars of this age, it is common to consider whether the infotainment hardware will require a software update or a screen replacement if responsiveness declines.
Standard oil and filter service using high-quality full synthetic oil to support the MDS system.
Comprehensive inspection of the air suspension system seals and a check of the brake pads given the vehicle's significant weight.
Major service milestone including the replacement of all 16 spark plugs and a refresh of the transmission fluid and filter.
Detailed inspection of the cooling system, including the water pump and serpentine belt, which may show signs of wear in NZ's varied climate.
Verify a consistent service history with oil changes performed at or before the recommended intervals to protect the valvetrain.
Inspect the sunroof tracks and drains for debris to ensure the cabin remains dry during heavy NZ rainfall.
Check the condition of the 20 or 22-inch tyres, as replacing these large sets represents a significant periodic investment.
Ensure the battery health is optimal, as low voltage can trigger various false error codes across the truck's many electronic modules.
Confirm that any outstanding factory recalls, particularly those related to the tailgate or electrical grounds, have been addressed by a specialist.
Estimated repair costs if issues arise
If this component needs attention in the future, the job usually involves removing the manifolds to replace broken studs with reinforced versions. This is a common consideration for HEMI owners to ensure engine refinement.
Depending on the car's history and exposure to gravel or salt, you might eventually need to budget for individual air corner replacements if the rubber seals perish or the bags begin to leak.
In cars of this generation, it is common to consider the long-term health of the lifters. If a mechanical tick becomes permanent, a top-end engine refresh might be required to maintain peak performance.
If the screen begins to show signs of delamination or internal hardware failure, you might eventually need to budget for a factory replacement unit or a specialized repair to maintain cabin functionality.
