⚡ The short verdict
The good news first: the engines and transmission are the strong part of this car. The 3.6L Pentastar V6 (292 to 300 hp) and the 5.7L, 6.4L, and supercharged 6.2L Hemi V8s are proven, and the ZF 8-speed automatic regularly clears 150,000 miles without internal failure. When a 2020 Charger has problems, it is almost always electronics, wear items, or oil-related, not a grenaded drivetrain.
This page ranks the issues by how often they show up, tells you the mileage window where each typically appears, and gives a real-world repair cost range so you can tell a $200 annoyance from a $4,000 dealbreaker.
📊 Most-reported 2020 Charger problems, ranked
Ranked by frequency of owner complaints. Costs are typical independent-shop ranges in U.S. dollars and will run higher at a dealer.
| Problem | Typical mileage | Repair cost | Severity |
|---|---|---|---|
| Uconnect / infotainment glitches | 20k–50k | $0–$1,500 | Low to medium |
| Electrical gremlins (sensors, modules, backup cam) | 30k–70k | $150–$900 | Low to medium |
| Premature brake wear / warped rotors | 30k–60k | $350–$700 per axle | Low |
| Front suspension clunks (control arms, sway links) | 40k–70k | $300–$900 | Medium |
| Hemi oil consumption / lifter tick | 60k–90k | $2,500–$4,500 | High |
| Harsh or hesitant 8-speed shifting | 40k–80k | $0–$400 | Low |
| Water leaks / trunk and HVAC condensation | any | $100–$500 | Low |
Notice the pattern: most issues are cheap-to-medium and software- or wear-related. The only line that crosses into dealbreaker territory is the Hemi lifter tick, and that one only affects a minority of V8 cars.
🔎 The breakdown, issue by issue
1. Uconnect and infotainment glitches
This is the number-one 2020 Dodge Charger problem by complaint volume. Owners report the touchscreen freezing, randomly rebooting, Bluetooth dropping calls, and the backup camera going black. Many cases are fixed for free with a Uconnect software update at the dealer. When the head unit itself fails, a replacement runs roughly $900 to $1,500. If your screen is dark or frozen, start with our guide on how to reset Uconnect before paying for anything.
2. Electrical gremlins
Beyond infotainment, the 2020 Charger can throw oddball electrical faults: a flickering instrument cluster, a TPMS light that will not clear, a faulty wheel-speed or ABS sensor, or a key-fob that needs reprogramming. Individual fixes are usually $150 to $900. If you have a dash warning light, look up the exact code first, for example P0301 for a cylinder-1 misfire or C1234 for a wheel-speed sensor, so you are not guessing.
3. Brakes and rotors
The Charger is a heavy car (roughly 4,000 to 4,600 lbs depending on trim and drivetrain), and the brakes wear faster than owners expect. Warped front rotors causing steering-wheel shudder under braking are a common complaint by 30,000 to 60,000 miles. A pad-and-rotor job is about $350 to $700 per axle. If you feel a pulsing brake pedal, see brakes shaking when stopping.
4. Front suspension clunks
Knocking or clunking over bumps usually traces to worn sway-bar end links, lower control-arm bushings, or strut mounts, typically appearing around 40,000 to 70,000 miles. End links are cheap (often under $250 installed); control arms push the bill toward $900. It is a comfort-and-handling issue, not a safety failure, if caught early.
5. Hemi oil consumption and the lifter tick
This is the one to take seriously on V8 cars. Some 5.7L Hemis burn a quart of oil every 1,500 to 3,000 miles, and a subset develop a lifter or camshaft tick. A faint tick on cold start that fades is usually harmless. A persistent tick after warm-up can mean a collapsed lifter, and a lifter-and-cam repair runs $2,500 to $4,500. Always run quality oil at the correct 5W-20 spec and check the level monthly. If you hear a tick, read up on the engine ticking noise symptom before assuming the worst.
6. Transmission shift quality
The ZF 8-speed is reliable, but some owners report harsh 1-2 shifts or hesitation. The fix is almost always a transmission-control-module software update or a fluid service, not a rebuild. Genuine internal failures are rare on the 2020 model.
⚠️ What to watch before you buy
If you are shopping for a used 2020 Charger, the goal is to separate normal wear from the few real dealbreakers. Walk away from, or heavily discount for, any of these:
- Persistent Hemi lifter tick. A tick that does not fade after warm-up is a potential $4,000 engine repair. Get it diagnosed cold and warm before you sign.
- Documented oil consumption with no records. A Hemi that burns oil and has spotty maintenance history is a gamble. Check for a clean dipstick and a recent oil change.
- Flood, frame, or unrepaired-airbag history. Run the VIN. Salvage and flood titles wreck the already-finicky electronics.
- Stacked open recalls. Dodge issued multiple recalls in this era covering items like wiring, fuel, and software. Open recalls are free to fix, but a car with several unaddressed campaigns signals a neglectful prior owner.
- Pulsing brakes plus clunking front end. Individually cheap, but together they mean deferred maintenance, so price accordingly.
None of these are unique to one Charger, and most are findable in a 30-minute test drive plus a VIN check. Always verify open recalls on the manufacturer or NHTSA site by VIN before purchase.
🧮 Is your specific Charger a problem? A quick framework
Use this to triage before spending money:
- Is there a dash warning light? Pull the code. A specific DTC turns "something is wrong" into a known, priced repair. Free scanners are at most parts stores.
- Is it a noise? A tick points to the engine (check oil first). A clunk over bumps points to suspension. A pulse under braking points to rotors.
- Is it the screen? Try a Uconnect reset and a software update before replacing anything. Most infotainment "failures" are software.
- Got a repair quote already? Run it through the quote checker to see if the shop's price is fair before you approve the work.
Most 2020 Charger problems fall into one of those four buckets, and three of the four are cheap. The fourth, an engine tick, is the only one worth losing sleep over.
❓ Frequently asked questions
📝 TL;DR
- Strong part: engines (V6 and Hemi V8) and the ZF 8-speed transmission, often 150k+ miles.
- Most common problem: Uconnect and electrical glitches, usually 20k to 50k miles, often fixed by a free software update.
- Watch items: brake/rotor wear and front suspension clunks, both cheap-to-medium fixes.
- The one real dealbreaker: a persistent Hemi lifter tick, a $2,500 to $4,500 repair on a minority of V8 cars.
- Buying advice: run the VIN, check open recalls, diagnose any tick cold and warm, and budget $400 to $800 a year.
