5.7L HEMI V8 with eTorque (Mild Hybrid)
Hybrid
While the engine is cold, listen carefully near the front wheel wells for a rhythmic ticking sound; in some HEMI engines of this era, the exhaust manifold bolts can stretch or snap, which may require attention to prevent exhaust leaks.
While decelerating to a stop, monitor how the engine transitions through the eTorque 'Stop/Start' phase; if the restart feels jarring or hesitant, it might be worth investigating the health of the 48V battery system and the drive belt.
While driving over varying road surfaces, listen for any 'clunking' from the rear; some owners have found that the rear glass seals or the high-mount brake light can benefit from a check-up if moisture is found in the cabin.
Test this by cycling the air suspension through all height settings (if equipped) while stationary; a slow or noisy compressor might suggest the system will eventually need a service to maintain its leveling performance.
Focus on cabin and engine air filters, and ensure the eTorque cooling system level is checked.
Common interval for replacing the 16 spark plugs (two per cylinder) to maintain the efficiency of the 5.7L Hemi.
Consider a comprehensive cooling system flush and a detailed inspection of the eTorque motor-generator drive belt.
In cars of this age, it's common to plan for a transmission fluid and filter service, despite being listed as a 'sealed' unit by some manufacturers.
Verify the use of high-quality synthetic 0W-20 oil to support the Multi-Displacement System (MDS).
Inspect the eTorque motor-generator belt for any signs of fraying or uneven wear.
Check the condition of the 12V starter battery, as it works in tandem with the 48V eTorque system.
Examine the transfer case and differential fluids, especially if the vehicle has been used for towing in NZ conditions.
Ensure the sunroof drains and rear window seals are clear of debris to prevent internal moisture.
Estimated repair costs if issues arise
Depending on the car's history, you might eventually need to budget for new manifold bolts or resurfacing if the 'Hemi Tick' develops due to heat cycles.
This is a specialized heavy-duty belt. If this component needs attention in the future, the cost reflects the labor required to access the motor-generator unit.
If the vehicle is equipped with Four-Corner Air Suspension, it’s wise to plan for potential airbag replacement as the rubber ages and develops small leaks.
While designed to last the life of the vehicle, you might eventually need to budget for a battery module replacement if the hybrid assistance efficiency declines over many years.
