All 4 Known Issues
The Commander frequently displays "Transmission Over Temp" warnings even when fluid level and condition are normal. The transmission control module (TCM) and powertrain control module (PCM) are prone to failure, causing the vehicle to stall, shift erratically, or enter limp mode. NHTSA Campaign 08V203000 addressed TCM issues, but many owners report the repairs did not fully resolve the problem. Over 216 powertrain complaints filed for the 2006 model year alone.
Common Symptoms
- Transmission Over Temp warning on dash
- Vehicle enters limp mode (3rd gear only)
- Erratic or harsh shifting
- Vehicle stalls while driving
- Transmission slips under load
- Check engine light with transmission codes
How to Fix
Start with a transmission fluid and filter change using ATF+4 (Mopar 68218057AB). Install an auxiliary transmission cooler ($100-200, Hayden 679 or Derale 13502) for sustained relief. Replace the TCM if faulty ($300-500 for module plus programming). Check transmission cooler lines for leaks. If overheating persists, the torque converter may be failing and need replacement ($800-1,500).

Parts and tips from 423+ owners who fixed this issue
- UpgradeInstall a Hayden 679 auxiliary transmission cooler to prevent overheating - inexpensive and effective (Hayden #679)
- UpgradeUse only Mopar ATF+4 (68218057AB) - incorrect fluid causes shift quality issues and overheating (Mopar #68218057AB)
- TipIf the transmission enters limp mode, pull over safely and let it cool for 15-20 minutes before driving again
The Commander can stall or lose engine power without warning at any speed. The problem is linked to multiple causes: faulty crankshaft position sensor, failing fuel pump, PCM software bugs, and throttle body issues. Over 173 engine complaints were filed for the 2006 model year. Some owners report engine compartment fires linked to electrical shorts in the PCM area.
Common Symptoms
- Engine stalls without warning
- Loss of power during acceleration
- No-start condition (cranks but no start)
- Check engine light with P0335/P0340 codes
- Intermittent rough idle
- Engine cuts out at highway speed
How to Fix
Replace the crankshaft position sensor (Mopar 56028373AB, $20-40 part, $100-200 labor) as the most common fix. Clean or replace the throttle body ($150-300). Check fuel pump pressure (should be 49-55 PSI). Update PCM software to the latest calibration at the dealer. For fire risk concerns, inspect wiring harness in the engine bay for chafing or heat damage.
What Owners Are Using
Parts and tips from 312+ owners who fixed this issue
- UpgradeReplace the crankshaft position sensor first (Mopar 56028373AB) - it is the most common cause of stalling and costs under $40 (Mopar #56028373AB)
- TipCarry a spare crankshaft position sensor in the glove box - they are known to fail without warning and the repair takes 15 minutes
- NoteStalling at highway speed is extremely dangerous - address this issue immediately
The Commander is plagued by random electrical issues where dashboard warning lights illuminate and extinguish without cause, the HVAC system shuts off randomly, and various accessories behave erratically. This can occur 1-15 times per day while driving or parked. The issues are often traced to corroded ground connections, a failing TIPM (Totally Integrated Power Module), or wiring harness degradation.
Common Symptoms
- Dashboard warning lights illuminate randomly
- HVAC system shuts off while driving
- Lights flicker or go dim
- Power windows operate intermittently
- Battery drains overnight
- Multiple systems fail simultaneously
How to Fix
Clean and reseal all chassis ground connections (there are 4-5 key ground points on the frame and engine). Inspect and clean battery terminals and ground cable. Check TIPM for signs of corrosion or relay failure. For TIPM issues, a remanufactured unit ($400-600) or relay bypass kit ($30-50 per relay) may be needed. Inspect main wiring harness for chafing near the firewall.

- TipStart by cleaning all chassis ground connections with sandpaper and applying dielectric grease - this fixes many Commander electrical issues for free
- TipA corroded battery ground cable is the single most common cause of Commander electrical gremlins
The Commander is susceptible to engine overheating caused by failing water pumps, cracked radiator tanks, leaking heater core connections, and thermostat failures. The radiator end tanks (plastic) are prone to cracking at the seam where they meet the aluminum core. Power steering cooler line leaks can also compound cooling issues. The 4.7L V8 is especially vulnerable.
Common Symptoms
- Temperature gauge runs hot or in red zone
- Coolant leak visible under vehicle
- Steam or sweet smell from under hood
- Low coolant warning light
- Heater blows cold air intermittently
- Coolant puddle at front of vehicle
How to Fix
Replace the thermostat and housing as preventive maintenance ($50-150). Upgrade to an all-aluminum radiator (Mishimoto or CSF) to eliminate plastic tank cracking ($200-400). Replace the water pump at 80,000-100,000 miles as preventive maintenance (Mopar 53021429AB for 3.7L, 53021578AD for 4.7L). Check and replace coolant hoses that show swelling or cracking. Flush cooling system every 30,000 miles.
What Owners Are Using
Parts and tips from 234+ owners who fixed this issue
- TipReplace the radiator proactively with an all-aluminum unit before the plastic tanks crack - it is a matter of when, not if
- UpgradeMopar water pump (53021429AB for 3.7L) should be replaced as preventive maintenance around 80-100k miles (Mopar #53021429AB)
