Common Problems & Known Issues

The 2010 Challenger sits on the LX platform with multiple powertrain options, and your experience varies wildly by engine choice. The 3.5L V6 and 5.7L Hemi are generally solid, but early transmission issues and some catastrophic 6.1L engine failures dominate the problem list.

Transmission Oil Cooler Failure (All Models)

Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Transmission fluid mixing with coolant creates strawberry milkshake in overflow tank, Rapid transmission damage if not caught early, Overheating or erratic shifting before total failure
Fix: Replace transmission cooler assembly and flush both cooling and transmission systems thoroughly. If contamination reached transmission, expect full rebuild. 4-6 hours labor for cooler only, 18-25 hours if trans needs rebuild.
Estimated cost: $800-1,200 cooler only, $3,500-5,500 with transmission rebuild

6.1L SRT8 Engine Failure (Dropped Valve Seats)

Occasional · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Sudden catastrophic loss of compression in one or more cylinders, Severe misfires and metal debris in oil, Engine knock followed by complete failure, Often happens without warning during normal driving
Fix: Valve seats separate from cylinder heads due to insufficient interference fit from factory. Requires complete engine rebuild or replacement with updated heads. 25-35 hours labor for short block plus head work.
Estimated cost: $8,000-14,000

Electric Power Steering (EPS) Failure

Occasional · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Complete loss of power assist, extremely heavy steering, EPS warning light on dash, Intermittent assist loss that becomes permanent, May occur suddenly while driving
Fix: Electric assist motor or control module fails. This was subject to recall but failures still occur outside recall scope. Replace steering column assembly. 3-4 hours labor.
Estimated cost: $1,200-1,800

Front Differential Bushing Failure (AWD Models Only)

Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Clunking from front end during acceleration or deceleration, Vibration at highway speeds, Visible differential sag or misalignment
Fix: Front diff mount bushings deteriorate, allowing excessive movement. Requires dropping front subframe for access. Aftermarket polyurethane upgrades available. 4-5 hours labor.
Estimated cost: $600-900

TIPM (Totally Integrated Power Module) Failures

Occasional · medium severity
Symptoms: Random electrical gremlins: wipers activate on their own, gauges go haywire, No-start conditions intermittently, Fuel pump relay clicking, stalling issues, Multiple unrelated warning lights
Fix: Central electrical control module known for internal relay failures and corrosion. Often requires TIPM replacement, though some shops attempt relay-level repairs. 2-3 hours labor for replacement.
Estimated cost: $800-1,400

Takata Airbag Inflator Recall Issues

Common · high severity
Symptoms: Recall notices for passenger and driver airbag inflators, No symptoms until deployment, when inflator can rupture sending shrapnel
Fix: Multiple recalls issued. Check VIN for open recalls before purchase. Dealer replacement at no cost, 1-2 hours per side.
Estimated cost: $0 (recall repair)

Rear Differential Pinion Seal Leaks (V8 Models)

Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Gear oil dripping from front of rear differential, Oil spots on driveway centered under diff, Low fluid can cause howling noise
Fix: Pinion seal deteriorates, especially on cars driven hard. Replace seal and fluid. Check pinion bearing preload while apart. 2-3 hours labor.
Estimated cost: $350-550
Owner tips
  • Check transmission cooler and coolant reservoir religiously every oil change—catching the milkshake early saves $4,000
  • If buying a 6.1L SRT8, get pre-purchase compression test and borescope inspection; many have already been rebuilt
  • Verify all Takata airbag recalls completed; parts were backordered for years and some owners never got them done
  • AWD models need front diff fluid changed every 30k to extend bushing life; Dodge says lifetime fill but that's optimistic
  • TIPM issues often intermittent; test drive in rain and cycle all electrical functions multiple times
Buy the 5.7L Hemi with service records showing the trans cooler was addressed; avoid 6.1L unless already rebuilt, and budget $2k for deferred maintenance on any example.
