Even stock Hellcat engines are capable of producing extraordinary performance, while modified versions frequently exceed 900–1,000 horsepower.

Common Hellcat 6.2 Engine Problems

Supercharger Bearing Issues

Early 2015–2016 Hellcats experienced supercharger snout bearing failures that caused whining noises at idle. Dodge later changed suppliers, significantly reducing the issue.

Fuel Rail Recall

Certain early-production Hellcat engines were recalled because fuel crossover hoses could leak, creating a potential fire hazard. Approximately 2,000 vehicles were affected.

Oil Cooler Line Leaks

Some 2017 model-year Hellcats experienced oil cooler feed and return line failures that could result in rapid oil loss.

Driveshaft And Drivetrain Stress

Because of the engine’s immense torque output, heavily driven Hellcats may experience drivetrain-related wear and failures. Enthusiast forums commonly report driveshaft and differential concerns on high-performance builds.

Cooling System Issues

Track use, aggressive driving, and modified applications can increase thermal stress and expose cooling system weaknesses.
