Dodge has issued a customer service notice for 345 Challenger SRT Demon 170 vehicles due to a potential crankshaft damper and bolt defect. Owners are advised to transport their vehicles to a dealership rather than driving them to prevent catastrophic engine failure.
Why it matters
The crankshaft harmonic damper is a critical component that counters resonance and torsional vibrations from the massive 6.2-liter Hemi V8 engine. Allowing the engine to operate with a compromised damper could lead to severe mechanical damage that impacts both the vehicle's longevity and operator safety.
The affected Dodge Challenger SRT Demon 170 is powered by a supercharged 6.2-liter Hemi V8 engine capable of producing 1,025 horsepower. Dodge identified the subset of 345 vehicles based on production periods linked to a specific component supplier.
