Common Problems & Known Issues

The 2012 Charger is a solid platform hampered by specific weak points: Pentastar V6 models face head gasket failures and left-side rocker arm defects, while the 5.7 Hemi suffers from lifter/cam failures and MDS issues. Transmission coolers fail across all powertrains, often contaminating fluid. Good chassis, problematic internals.

Pentastar 3.6L V6 Left Cylinder Head Failure

Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Ticking/knocking from left bank, P0300-series misfire codes, Coolant consumption without visible leaks, White exhaust smoke on cold start
Fix: Left head suffers rocker arm wear and head gasket failure. Requires left head R&R, new gasket set, resurface or replacement head, timing chain inspection. 12-16 labor hours. Often find contaminated oil from coolant intrusion requiring flush.
Estimated cost: $3,200-5,500

5.7L Hemi Lifter and Camshaft Failure

Common · high severity
Typical onset: 60,000-110,000 mi
Symptoms: Cold-start ticking that persists, P0300 codes with cylinder-specific misfires, Metal shavings in oil, Check engine light with cam/crank correlation codes
Fix: MDS (cylinder deactivation) lifters fail, wiping cam lobes. Requires both camshafts, all 16 lifters, sometimes rocker arms. Engine-out preferred for thorough cleaning of debris. 18-24 labor hours. Oil system flush mandatory.
Estimated cost: $4,500-7,000

Transmission Oil Cooler Internal Failure

Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Transmission slipping or delayed engagement, Pink/milky transmission fluid, Coolant level dropping, Transmission overheating warnings
Fix: Internal cooler in radiator fails, allowing coolant and ATF to mix. Requires new radiator, complete transmission flush (often multiple cycles), new torque converter, filter. If caught late, full transmission rebuild needed. 6-10 hours for cooler/flush, add 16-20 for transmission.
Estimated cost: $1,800-3,200 (cooler/flush only); $4,500-6,500 (with transmission rebuild)

TIPM (Totally Integrated Power Module) Failure

Occasional · medium severity
Symptoms: Random no-start conditions, Fuel pump not priming, Wipers/windows operating on their own, Multiple electrical faults with no pattern
Fix: Central body control module develops internal relay failures, especially fuel pump relay. Replacement TIPM requires programming to VIN. 2-3 labor hours. Chrysler issued extended warranty on some VINs but most 2012s now out of coverage.
Estimated cost: $800-1,400

Alternator Failure (High-Output Models)

Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Battery light intermittent then constant, Voltage gauge dropping below 12V, Electrical accessories dimming, Whining noise from alternator pulley
Fix: 160-amp and 220-amp alternators (especially on V8 models) fail prematurely. Regulator burns out or bearings seize. Straight replacement job. 1.5-2.5 hours depending on V6 vs V8 accessory routing.
Estimated cost: $450-750

Water Pump Failure (3.6L Pentastar)

Occasional · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Coolant weeping from timing cover area, Squealing from front of engine, Overheating under load, Visible coolant drips below timing cover
Fix: Pentastar runs water pump off timing chain internally. Failure requires front timing cover removal, new chain tensioners/guides recommended while in there. 6-8 labor hours. Critical to not overheat engine or head gasket follows.
Estimated cost: $1,200-1,900

Rear Differential Pinion Seal Leak

Occasional · low severity
Typical onset: 80,000-140,000 mi
Symptoms: Gear oil puddle under rear center of car, Clicking from rear on turns (if run low), Visible oil on rear differential housing
Fix: Pinion seal hardens and leaks. Requires driveshaft removal, pinion nut torque verification, new seal. Simple job but easy to miss until significant fluid loss. 2-3 labor hours.
Estimated cost: $350-600
Owner tips
  • Change oil every 5,000 miles maximum on Hemi engines — MDS lifters are oil-quality sensitive, extended intervals accelerate failure
  • Inspect transmission fluid color every 30k miles; catch cooler failure before it destroys transmission
  • Pentastar V6: watch for coolant consumption and address head gasket seepage immediately to prevent catastrophic head failure
  • Avoid extended idling on V8 models — insufficient oil pressure to MDS components accelerates cam wear
Buy the 5.7 Hemi only if lifters/cam already done or budget $5k for inevitable repair; Pentastar V6 is a gamble past 80k miles unless head work documented; solid chassis can't overcome these engine gremlins for most buyers.
