Overview

The 2020 Dodge Charger is a full-size performance sedan that blends classic American muscle styling with modern four-door practicality. It’s ideal for drivers who want strong straight-line power, available all-wheel drive on V6 models, and a roomy cabin without moving into an SUV. The Charger sits in a niche market position as one of the last mainstream rear-wheel-drive V8 sedans, competing more on character and horsepower than on luxury-car polish. For 2020, it continues as part of the LD-generation Charger (introduced for 2011 and heavily refreshed for 2015), with ongoing tech and trim updates rather than a full redesign.

Key Features

1) Engine lineup for multiple driving styles: a 3.6L Pentastar V6 (around 292–300 hp depending on trim), a 5.7L HEMI V8 (around 370 hp), a 6.4L Scat Pack V8 (around 485 hp), and the supercharged 6.2L HEMI V8 in Hellcat form (around 707 hp). 2) Rear-wheel drive is standard for most trims, with available all-wheel drive on V6 models for improved four-season traction. 3) Available performance hardware: Brembo brakes (common on Scat Pack/Hellcat), sport suspension tuning, and wider performance tires on higher trims. 4) Modern infotainment: Uconnect touchscreen systems (typically 7-inch or available 8.4-inch) with Apple CarPlay and Android Auto support on most configurations. 5) Strong highway comfort and space: a large trunk and adult-friendly rear seat make it more usable day-to-day than many performance coupes.

Common Issues & Reliability

Shoppers researching 2020 Dodge Charger reliability often find that overall durability can be solid when maintained, but there are repeat complaints to be aware of. Common 2020 Dodge Charger problems tend to fall into a few buckets: electrical glitches, drivetrain wear on hard-driven cars, and cooling/charging-system concerns. 1) HEMI “tick” / valvetrain noise and lifter wear: Some V8 owners report ticking noises that can be related to lifter/roller wear or exhaust manifold bolt issues. It may show up anywhere from 30,000 to 80,000 miles depending on use, idle time, and oil-change habits. Not every tick is catastrophic, but it’s a key item to diagnose early. 2) Electrical and infotainment issues: Reports include Uconnect freezing/rebooting, Bluetooth pairing problems, and occasional warning lights tied to sensors or low battery voltage. These can appear sporadically even under 50,000 miles and may be resolved with software updates, battery replacement, or module/sensor diagnostics. 3) Cooling system and thermostat/water pump leaks: Some owners report coolant seepage, thermostat housing concerns, or water pump leaks that can show up in the 40,000–90,000-mile range. Overheating risk is the main concern if a small leak goes unnoticed. 4) Transmission behavior and driveline wear: The 8-speed automatic is generally well-liked, but some drivers note rough shifting, delayed engagement, or shudder-like behavior—often influenced by fluid condition, software updates, or hard use. On higher-power trims, aggressive launches can accelerate rear tire wear and stress driveline components over time.
