Common Problems & Known Issues

The 2007 Chrysler Aspen is essentially a rebadged Durango on the same WK platform as the Grand Cherokee. It shares the solid rear axle, independent front suspension, and all the typical mid-2000s Chrysler drivetrain quirks — transmission cooler failures being the big one.

Transmission Oil Cooler Failure Leading to Strawberry Milkshake of Death

Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Pink or milky fluid in transmission dipstick or radiator overflow, Transmission slipping or harsh shifting after coolant contamination, Coolant loss with no visible external leaks, Check engine light with transmission-related codes
Fix: The internal transmission cooler in the radiator fails, mixing coolant and ATF. This destroys the transmission if not caught early. Fix requires radiator replacement, complete transmission flush (or rebuild if contaminated), new coolant, and external cooler install recommended. 6-10 hours labor if trans is salvageable, 15-20 if rebuild needed.
Estimated cost: $1,200-$4,500

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

Occasional · high severity
Typical onset: 100,000-180,000 mi
Symptoms: Ticking or tapping noise from engine, especially on cold start, Check engine light with misfire codes or cylinder deactivation faults, Loss of power or rough idle, Metal shavings in oil on analysis
Fix: The MDS lifters on cylinders 1, 4, 6, 7 can collapse or the cam lobes wear prematurely, especially with extended oil change intervals. Requires cam replacement, all 16 lifters, and often rocker arms. Some cases destroy the engine entirely if lifter fragments circulate. 12-16 hours labor for cam/lifter job; full rebuild or short block if severe.
Estimated cost: $3,500-$8,000

4.7L V8 Engine Sludge and Bearing Failure

Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Knocking or rumbling noise from lower engine, worse under load, Low oil pressure warning or gauge dropping at idle, Excessive oil consumption between changes, Metallic debris in oil filter
Fix: The 4.7L is prone to sludge buildup with poor maintenance, leading to spun rod or main bearings. Often requires full engine rebuild or short block replacement. 18-24 hours labor for short block swap with all accessories transferred.
Estimated cost: $4,500-$7,500

Front Differential and Transfer Case Leaks

Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Gear oil puddles under front of vehicle, Whining or grinding noise from front axle during turns (4WD models), Visible oil seepage around front diff cover or transfer case seams, Burning oil smell after highway driving
Fix: Front axle and transfer case seals wear out, especially the front output shaft seal and pinion seal. If caught early, just seals and fluid; if run low, bearings damaged. 3-5 hours labor for seal replacement and fluid service.
Estimated cost: $600-$1,200

Rear HVAC Blower Motor and Evaporator Core Leaks

Occasional · low severity
Typical onset: 90,000-150,000 mi
Symptoms: Rear A/C blows weak or not at all, Coolant smell in cabin or wet passenger-side rear carpet, Squealing or grinding from behind rear passenger trim, Fogged windows that won't clear
Fix: Rear blower motor fails (common on three-row SUVs) or rear evaporator develops pinhole leaks. Blower is 2 hours; evaporator requires dash and console disassembly, 8-10 hours, plus A/C recharge.
Estimated cost: $400-$2,000

Fuel Pump and Fuel Filter Clogging

Occasional · medium severity
Typical onset: 100,000-140,000 mi
Symptoms: Hard starting or extended crank time, especially when hot, Sputtering or loss of power under acceleration, Engine stalling at idle or low speed, Whining noise from fuel tank area
Fix: In-tank fuel pump fails or filter sock clogs with sediment. Pump replacement requires dropping the tank. 2-3 hours labor, straightforward job but tank must be near empty.
Estimated cost: $600-$1,000

Front Upper Control Arm Ball Joints

Common · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Clunking over bumps from front suspension, Wandering or loose steering feel, Uneven tire wear on inside or outside edges, Popping noise when turning at low speed
Fix: Upper ball joints wear out and aren't serviceable separately — entire control arm assembly required. Both sides typically done together. 3-4 hours labor plus alignment.
Estimated cost: $800-$1,400
Owner tips
  • Install an external transmission cooler immediately if buying used — the internal radiator cooler will fail, it's only a matter of when
  • On HEMI models, change oil every 5,000 miles maximum with quality synthetic to delay MDS lifter issues; consider MDS delete if doing cam work
  • Check for service records showing differential and transfer case fluid changes every 50k — these are often neglected and lead to expensive failures
  • Pre-purchase inspection should include oil analysis and compression test on high-mileage examples, especially 4.7L motors
Buy only with full service records and budget $2k-3k for deferred maintenance; the trans cooler issue alone makes this a gamble without an external cooler already installed.
