•Run VIN through NHTSA recall database to confirm ALL Takata airbag and alternator recalls are completed before proceeding
•Start cold and listen for valve train ticking at idle, a sign of MDS lifter wear; budget accordingly if present
•Check oil level on dipstick and ask for documented oil change history, look for evidence of regular sub-8,000 km intervals
•Test all gauge cluster lighting in darkness or shade, partial blackouts are a known fault, replacement is costly
•Load-test the battery and measure alternator output voltage (should be 13.8-14.5V at idle), electrical failures are a documented pattern
•Verify whether MDS is still active or has been disabled via tune/device, a disable tune is a positive sign of proactive ownership
•Confirm whether the car has the 5-speed automatic (2011-2014) or the ZF 8-speed automatic (2015+), the 8-speed is the more reliable transmission of the two

Airbag, Passenger Side Frontal Inflator Module (Takata)
Inflator can rupture upon deployment, sending metal fragments into cabin. Risk of serious injury or death.
Electrical System, Alternator / Generator / Regulator
Alternator may fail causing loss of electrical power and potential vehicle stall.
Airbag, Frontal Passenger Side (Secondary Takata Expansion)
Expanded recall population covering 2009-2013 models for same Takata inflator rupture defect.
Airbag, 2011-2012 Model Year (Separate Airbag Recall)
Airbag system fault on 2011-2012 Challenger potentially affecting deployment reliability.

✓6.4L HEMI V8 is a fundamentally strong, large-displacement engine with proven long-term durability when maintained
✓Massive aftermarket support, supercharger kits, tunes, and performance parts widely available
✓Long production run (2011-2023) means parts availability is excellent
✓Community widely reports 5.7 and 6.4 HEMIs reaching 300,000+ km with regular oil changes
✓ZF 8-speed automatic (2015+) reported positively for reliability compared to the earlier 5-speed automatic
✓High-torque output delivered in naturally aspirated form, no turbo system to maintain

485 hp · 644 Nm
2015-2023
The core 6.4L block, heads, and MDS system are unchanged across both outputs, so there is no inherent durability difference between the 470hp and 485hp tunes. The real practical distinction is the transmission and recall window: 2011-2014 cars only offer the older 5-speed automatic and fall squarely into the alternator and Takata recall population, so recall verification is essential on these. 2015+ cars offer the more reliable ZF 8-speed automatic alongside the manual and pick up the small power bump as a byproduct of breathing improvements. Buy on transmission type, documented MDS handling, and recall completion, not on the hp number alone.
