The 2019 Challenger is mechanically solid for a muscle car, but the ZF 8-speed automatic has a weak link in its cooler system, and high-output Hemi engines (especially 6.2L Hellcat) face catastrophic oiling and bearing failures when pushed hard or neglected.
Transmission Oil Cooler Failure (ZF 8HP70/8HP90)
Common · high severityTypical onset: 60,000-90,000 mi
Symptoms: Pink milkshake in coolant overflow (transmission fluid mixing with coolant), Transmission slipping or delayed shifts, Check engine light with trans temp codes, Coolant level mysteriously dropping
Fix: Replace transmission oil cooler and flush both coolant and transmission systems. Sometimes requires internal trans flush if contamination is severe. 4-6 hours labor if caught early, 12+ if trans is damaged.
Estimated cost: $800-1,500 for cooler replacement; $3,500-5,000 if transmission internals are damaged
Connecting Rod and Main Bearing Failure (6.2L Hellcat, 6.4L 392)
Occasional · high severityTypical onset: 40,000-80,000 mi on hard-driven examples
Symptoms: Knocking or ticking noise from bottom end, especially at idle, Sudden catastrophic failure with metal chunks in oil pan, Low oil pressure warning, Excessive blow-by from crankcase
Fix: Full short block replacement or engine rebuild with upgraded bearings. Root cause is oiling system design under sustained high RPM and aggressive driving. 25-35 hours labor for engine removal and rebuild.
Estimated cost: $8,000-15,000 depending on block damage and whether heads need work
Piston Ring and Cylinder Scoring (5.7L and 6.4L Hemi)
Occasional · high severityTypical onset: 80,000-120,000 mi
Symptoms: Heavy oil consumption (1 quart per 1,000 miles or worse), Blue smoke on cold start or acceleration, Fouled spark plugs on specific cylinders, Loss of compression on leak-down test
Fix: Requires cylinder head removal, honing cylinders, and replacing piston rings at minimum. Often need full pistons if scoring is deep. 18-24 hours labor for both banks.
Estimated cost: $3,500-6,500 for rings and honing; $7,000-10,000 if pistons and machine work needed
Transmission Mount Failure
Common · low severityTypical onset: 50,000-80,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle in gear, Driveline shudder during acceleration, Visible drooping or cracking of rubber mount
Fix: Replace transmission mount and crossmember bushings. High-torque V8 models eat these regularly. 1.5-2 hours labor.
Estimated cost: $250-450
Head Gasket Failure (6.2L Hellcat)
Rare · high severityTypical onset: 50,000-100,000 mi on boosted/tuned cars
Symptoms: White smoke from exhaust, Coolant disappearing with no visible leaks, Overheating under boost, Bubbles in coolant reservoir when running
Fix: Head gasket replacement on supercharged engine requires head removal, resurfacing, and ARP stud upgrade recommended. 20-28 hours labor for both sides.
Estimated cost: $4,500-7,000
Backup Camera Failure (Recall 23V-396)
Occasional · medium severitySymptoms: Intermittent black screen when shifting to Reverse, Camera image freezing or pixelated, Complete camera failure
Fix: Software update or camera module replacement under recall. Dealer-only fix, typically 1 hour. Check if recall completed before purchase.
Estimated cost: $0 under recall; $400-650 if out of pocket
Buy the V6 or 5.7L with service records and you'll have a reliable muscle car; the 392 and Hellcat are money pits unless you're prepared for expensive engine work or the previous owner babied it.
