Check this by accelerating moderately in a higher gear | Observation: Be mindful of any shuddering or hesitation, as the 6-speed 6L80E automatic transmission in these V8 models can sometimes show signs of wear in the torque converter or valve body at higher mileages.
While driving on an uneven road surface | Observation: Listen for any knocking or clunking from the front end, which may indicate that the control arm bushes or sway bar links are beginning to show their age—a common consideration for VE platforms.
At a standstill in 'Park' with the bonnet open | Observation: Observe the engine's idle smoothness; while the Gen IV V8 is generally robust, intermittent vibrations could suggest that the engine mounts may eventually require inspection.
Before your drive, check the coolant reservoir and oil filler cap | Observation: Look for any signs of milky residue, as the timing chain covers on these engines can occasionally develop minor coolant leaks that are worth monitoring as part of your regular checks.
Usually the time to evaluate suspension bushes and the condition of the transmission fluid cooling lines.

Schedule an engine oil and premium filter change every 7,500km to 10,000km to keep that Gen IV V8 happy.
Inspect the transmission fluid color and smell during your regular service intervals to ensure it remains clear and free of burnt odors.
Check the brake fluid moisture levels annually, especially since these heavy sedans rely on their braking system quite significantly.
Keep an eye on the cabin air filter to ensure the dual-zone climate control continues to operate efficiently for your comfort.
Periodically check the differential oil level, as a quiet differential is key to enjoying the refined cruise of a Calais.
Estimated repair costs if issues arise
If the transmission begins to shift harshly or shudder under load, you might eventually need to budget for a valve body service or overhaul to restore smooth operation.
Because the VE platform is quite heavy, you might eventually need to budget for replacing front control arm bushes and struts to keep the car's 'Luxury' ride quality intact.
If you notice a rhythmic tapping noise on cold starts, it's common to consider budgeting for a timing chain kit replacement to ensure the long-term reliability of the engine.
