Common Problems & Known Issues

The 2009 Chrysler Aspen is essentially a rebadged Dodge Durango on the same platform, sharing the HEMI 5.7L and 4.7L V8 options with known weaknesses in the multi-displacement system, transmission cooling, and differential components. Major engine failures and transmission cooler issues dominate the repair landscape for higher-mileage examples.

MDS (Multi-Displacement System) Lifter and Camshaft Failure - 5.7L HEMI

Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Ticking or tapping noise on cold start that may disappear when warm, Check engine light with misfire codes (P0300-series), Rough idle and loss of power, Metal shavings in oil
Fix: MDS lifters collapse causing cam lobe wear. Requires removing both cylinder heads, replacing all lifters, camshaft, and often rockers. Budget 18-24 hours labor plus parts. Many shops now recommend MDS delete kits to prevent recurrence.
Estimated cost: $3,500-6,500

Transmission Oil Cooler Line Failure at Radiator

Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Pink milkshake appearance in coolant reservoir (trans fluid mixing with coolant), Transmission slipping or delayed engagement, Overheating transmission, Coolant loss with no external leaks
Fix: Factory cooler lines corrode internally or the radiator-mounted cooler fails, causing cross-contamination that destroys the transmission. Requires radiator replacement, full transmission flush or rebuild depending on contamination severity, and all cooling system hoses. If caught late, transmission rebuild adds 12-15 hours. Early catch: 4-6 hours for radiator and flush.
Estimated cost: $800-1,200 (early catch) / $3,000-5,000 (with transmission rebuild)

Rear Differential Pinion Bearing and Seal Failure

Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Howling or whining noise from rear that increases with speed, Clunking on acceleration or deceleration, Fluid leak at pinion seal, Vibration at highway speeds
Fix: Pinion bearings wear prematurely, especially on 3.92 and 4.10 gear ratios in tow-package trucks. Requires differential disassembly, bearing and seal replacement, gear pattern setup. 6-8 hours labor. Sometimes catches shops off-guard because requires specialized setup tools and experience.
Estimated cost: $1,200-2,200

4.7L V8 Valve Seat Recession and Dropped Seats

Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Sudden catastrophic loss of power, Severe engine knocking or rattling, Misfire codes on one or more cylinders, Metal debris in oil or coolant
Fix: Factory valve seats can drop out of the head casting, usually on passenger side. When it happens, the valve seat falls into the cylinder causing catastrophic damage to pistons, cylinder walls, and sometimes crankshaft. Requires complete engine rebuild or replacement. 25-35 hours labor for in-chassis rebuild.
Estimated cost: $4,500-8,000

Transmission Mount Collapse

Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Excessive vibration at idle in gear, Visible sagging of transmission tailhousing, Driveline shudder on acceleration
Fix: Rubber transmission mount deteriorates, causing driveline angle changes and vibration. Simple replacement job but requires supporting transmission. 1.5-2.5 hours labor. Often ignored until it causes U-joint or driveshaft issues.
Estimated cost: $200-400

EVAP System Leak Detection Pump Failure

Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Check engine light with P0456 (small EVAP leak) or P0442 codes, No drivability issues, Fails emissions testing in some states
Fix: Leak detection pump (LDP) diaphragm fails or pump motor quits. Located near fuel tank, accessible from underneath. Includes checking for actual leaks in system first (loose gas cap, cracked lines). 1-1.5 hours labor if just pump replacement.
Estimated cost: $250-450

Takata Airbag Inflator Recall Complications

Common · high severity
Symptoms: NHTSA recall notices, Airbag light may or may not be illuminated, Potential for explosive airbag deployment injury
Fix: Multiple recalls for driver and passenger Takata inflators. Parts availability has been problematic. Owners should check recall status by VIN and schedule with dealer for free replacement. Some owners report multi-month waits for parts. Not a DIY repair.
Estimated cost: $0 (recall repair at dealer)
Owner tips
  • On 5.7L HEMI models, switch to quality synthetic oil and consider 4,000-mile intervals to extend MDS lifter life—many failures correlate with extended drain intervals
  • Check transmission fluid color religiously every 15k miles; any pink tint in coolant means immediate radiator replacement before transmission is ruined
  • Install an auxiliary transmission cooler if towing regularly—factory cooler is marginal at best
  • Rear differential should get fluid changes every 30k-40k if towing or using 4WD frequently; factory fill-for-life recommendation is optimistic
  • Address transmission mount clunks early—collapsed mounts accelerate U-joint and driveshaft wear
Hard pass unless under 80k miles with obsessive maintenance records and MDS already addressed—too many expensive grenades waiting to go off, especially the trans cooler and HEMI lifter issues that can total the vehicle.
