3.6L (Pentastar V6) - SXT
Petrol
While idling in Park, listen closely for a faint 'ticking' sound from the engine; this is common in high-mileage Pentastar engines and may indicate valve train wear.
Check the transmission's responsiveness by performing a gentle acceleration from a stop to ensure the 8-speed automatic shifts smoothly without hesitation or harsh jolts.
While driving, navigate over a few bumps and listen for any knocking sounds from the suspension, as the Challenger’s heavy front end can put extra wear on control arm bushings over time.
Test all infotainment features and electronic door locks while the engine is running; these models occasionally experience electrical gremlins related to battery health or grounding points.
Time to inspect the suspension components and cooling system hoses for signs of aging or perishing.
Consider a transmission fluid flush if it hasn't been documented, and keep an eye on the water pump, which can sometimes show signs of wear at this stage.
General assessment of the alternator and starter motor is recommended, as these electrical components often reach the end of their design life around this interval.
Stick to high-quality synthetic 5W-20 oil changes every 10,000km to keep that Pentastar V6 running smooth.
Keep an eye on your coolant levels and ensure the system is flushed every few years to prevent any radiator sediment build-up.
Check your tyre pressure regularly; the Challenger's weight makes correct inflation vital for even tread wear.
Ensure the air filter is kept clean, as it helps the engine breathe better and maintains that signature throttle response.
Keep your battery terminals clean and tight, as modern electronics in these vehicles are quite sensitive to voltage fluctuations.
Estimated repair costs if issues arise
In cars of this age, it's common to consider that the water pump may eventually need a refresh. If you notice a small coolant weep or hear a bearing whine, it is a good idea to address it to avoid overheating.
Given the Challenger's heavy frame, you might eventually need to budget for refreshing the front suspension control arms and struts to maintain that smooth handling feel.
While the 8-speed transmission is robust, preventative maintenance is key. If you find the shifting feels a bit sluggish, a fluid and filter service is a wise future investment.
