The 2010 Commander's final model year brings well-known WK platform issues: catastrophic 3.7L engine failures, transmission cooler leaks mixing ATF with coolant, and transfer case problems that strand vehicles. The 5.7L Hemi is the most reliable powertrain option, but even it can't escape the platform's other demons.
3.7L V6 Catastrophic Engine Failure (Cylinder Head/Block Cracking)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Coolant loss with no external leaks, White exhaust smoke on cold start, Overheating episodes, Milky oil on dipstick, Rough idle progressing to dead cylinder
Fix: The 3.7L PowerTech is notorious for cylinder head cracking between valves and coolant intrusion into cylinders. Requires complete engine replacement or rebuild with updated heads. 18-24 labor hours for longblock swap, more for in-chassis rebuild.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Failure (Coolant-ATF Contamination)
Common · high severityTypical onset: 70,000-110,000 mi
Symptoms: Transmission slipping or shuddering, Pink milkshake in coolant reservoir, Transmission overheating warnings, Strawberry milkshake on ATF dipstick, No-start after sitting (hydrolock from coolant in trans)
Fix: Internal cooler in radiator fails, allowing coolant and ATF to mix—destroys transmission quickly. Requires radiator replacement, complete transmission flush or rebuild, all cooling system lines flushed. If caught early (just cooler), 4-6 hours; if trans damaged, add 12-16 hours for rebuild.
Estimated cost: $800-1,200 (cooler only), $3,500-5,000 (with trans rebuild)
Transfer Case NV140 Chain Stretch and Failure
Occasional · high severityTypical onset: 90,000-140,000 mi
Symptoms: Grinding or howling noise in 4WD, Jumping out of 4WD mode, Service 4WD message on dash, Metal shavings in transfer case fluid, Complete loss of 4WD or binding in turns
Fix: NV140 transfer case chain stretches, causing noise and eventual catastrophic failure. Requires transfer case removal and rebuild or replacement. 8-10 labor hours for R&R and rebuild.
Estimated cost: $2,200-3,800
TIPM (Totally Integrated Power Module) Failures
Occasional · medium severitySymptoms: Fuel pump not priming (no start), Wipers running on their own, Windows operating randomly, Gauges going haywire, Intermittent no-crank, ABS and traction control lights
Fix: The TIPM develops internal relay failures and corrosion on circuit boards. Chrysler issued extended warranty coverage that's now expired. Requires TIPM replacement and programming. 2-3 labor hours plus expensive module.
Estimated cost: $800-1,400
Front Lower Control Arm Bushing Deterioration
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking over bumps from front end, Wandering steering feel, Uneven tire wear on inside edges, Vibration under braking, Alignment won't hold
Fix: OEM bushings fail prematurely, causing alignment issues and poor handling. Requires replacement of lower control arms (bushings aren't sold separately by Chrysler). 3-4 hours for both sides with alignment.
Estimated cost: $600-900
Rear Liftgate Support Struts and Latch Failure
Common · low severityTypical onset: 50,000-90,000 mi
Symptoms: Liftgate won't stay open, Slow or sagging liftgate opening, Liftgate won't latch securely, Power liftgate operates intermittently, Latch corrosion visible
Fix: Struts weaken and latch mechanisms corrode, especially in salt states. Struts are 0.5 hour job; latch assembly is 1.5-2 hours with trim removal.
Estimated cost: $150-300 (struts), $300-500 (latch)
Only consider a used 2010 Commander with the 5.7L Hemi, full service records proving cooler and transfer case maintenance, and money set aside for the inevitable TIPM failure—otherwise, walk away.
