Common Problems & Known Issues

The 2018 Charger LX platform is fundamentally solid but shows critical weaknesses in transmission oil cooling and catastrophic Hemi engine failures tied to lifter/cam issues. V6 models are generally more reliable, while Hemi variants (especially 5.7L and 6.4L) face expensive internal engine failures at surprisingly low mileage.

Transmission Oil Cooler Failure (8-Speed ZF)

Common · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Transmission overheating warning, Harsh shifting or delayed engagement, Metal contamination in fluid, Complete transmission failure if not caught early
Fix: Replace oil cooler assembly and flush transmission system thoroughly. If metal debris circulated, full transmission rebuild or replacement required. 4-6 hours labor for cooler only, 12-18 hours for transmission R&R.
Estimated cost: $800-1,200 (cooler only), $3,500-5,500 (with transmission damage)

Hemi Lifter/Camshaft Failure (5.7L and 6.4L)

Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Cold-start ticking/tapping that persists, MDS activation roughness (cylinder deactivation), Metal shavings in oil, Check engine light with misfire codes, Catastrophic engine failure with rod knock
Fix: Roller lifters fail, wipe camshaft lobes, send debris through oil system damaging bearings. Requires complete engine teardown: camshaft, all lifters, bearings inspection, often pistons/rings. Many shops recommend short block or complete engine. 20-30 hours labor minimum.
Estimated cost: $4,500-8,000 (cam/lifter job), $8,000-12,000 (short block/rebuild)

Driveshaft Center Support Bearing Failure (AWD models)

Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Vibration under acceleration around 40-60 mph, Clunking from underneath when engaging drive, Rumbling noise that changes with speed
Fix: Center carrier bearing wears out, driveshaft becomes unbalanced. Replace center support bearing assembly and inspect U-joints. Some require full driveshaft replacement if splines are worn. 2-3 hours labor.
Estimated cost: $400-800

Fuel Pump Control Module Failure

Occasional · high severity
Symptoms: No-start with full tank of gas, Intermittent stalling at any speed, Engine dies and won't restart until cool, No fuel pressure at rail
Fix: Module mounted to fuel tank fails, cuts power to pump. Often misdiagnosed as fuel pump itself. Replace control module, accessed by dropping tank or through trunk access panel on some models. 1.5-2.5 hours labor.
Estimated cost: $350-650

Front Transmission Mount Collapse

Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Harsh clunk when shifting from park to drive, Vibration at idle in gear, Excessive driveline movement visible from underneath
Fix: Hydraulic transmission mount fails, allows excessive engine/trans movement. Replace mount, straightforward job. 1-1.5 hours labor.
Estimated cost: $250-400

Backup Camera Wiring Corrosion

Occasional · low severity
Symptoms: Intermittent backup camera display, Screen shows 'camera unavailable', Works when dry, fails when wet
Fix: Wiring harness behind taillight or at trunk hinge corrodes. Related to NHTSA recall but not all units covered. Trace wiring, repair/replace affected sections, reseal connections. 1-2 hours labor.
Estimated cost: $150-350
Owner tips
  • Change transmission fluid every 60,000 miles regardless of 'lifetime fill' claim — prevents cooler and valve body issues
  • On Hemi engines, use quality full-synthetic oil and change every 5,000 miles maximum to delay lifter failure
  • Disable MDS (cylinder deactivation) with tuner if keeping long-term — reduces lifter stress significantly
  • Inspect driveshaft center bearing on AWD models during every alignment or suspension work
Buy a V6 model if you want reliable transportation; avoid used Hemis unless full engine service history is documented and you budget $5K for eventual valve train work.
