The 2008 Jeep Commander shares the WK platform with the Grand Cherokee and suffers from similar chronic issues: catastrophic 3.7L engine failures, problematic rear suspension components, and transmission oil cooler contamination that can destroy the transmission. The 4.7L is more durable, but the entire platform demands vigilant maintenance.
Symptoms: Sudden loss of power and severe engine knock, Metal shavings in oil or coolant, Cylinder misfire codes (often multiple cylinders), Coolant mixing with oil (milky dipstick)
Fix: The 3.7L PowerTech engine has a factory defect where valve seats separate from the cylinder head, dropping into cylinders and destroying pistons, rings, cylinder walls, and sometimes the crank. Requires complete engine rebuild or replacement. 25-35 labor hours for used engine swap, 40+ for full rebuild.
Symptoms: Pink or strawberry milkshake appearance in coolant reservoir, Transmission slipping or delayed engagement, Overheating transmission (limp mode), Sweet smell from exhaust or coolant overflow
Fix: Factory cooler inside radiator fails, allowing coolant and ATF to mix. Coolant destroys transmission clutches and valve body within days of contamination. Requires radiator replacement, transmission flush or rebuild, and all cooler lines flushed. If caught early (just cooler failure), 6-8 hours. If transmission damaged, add 12-18 hours for rebuild.
Symptoms: Clunking from rear suspension over bumps, Wandering or unstable handling at highway speeds, Excessive rear tire wear (inner or outer edge), Visible separation or play in lower control arm bushing
Fix: Rear lower control arms use pressed-in ball joints and bushings that fail prematurely, especially with rust belt exposure. Ball joint can separate catastrophically. Both sides should be replaced together with alignment. 3-4 hours per side, 6-7 total with alignment.
Estimated cost: $1,200-1,800
TIPM (Totally Integrated Power Module) Failures
Occasional · high severity
Symptoms: Fuel pump cycles constantly or not at all (no start), Wipers or headlights operate on their own, Multiple intermittent electrical gremlins (windows, locks, gauges), ABS and traction control warning lights with no stored codes
Fix: The TIPM (integrated fuse/relay box) develops internal corrosion or solder joint failures, causing random electrical chaos. Dealer-only part in 2008, requires programming. Some independent shops can repair solder joints, but success rate varies. 2-3 hours replacement plus programming time.
Estimated cost: $800-1,400 (used/repaired unit), $1,800-2,500 (new OEM)
Front Drive Shaft CV Joint and U-Joint Failure
Common · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Clicking or popping during turns (especially tight, low-speed), Vibration during acceleration in 4WD mode, Clunking when shifting from drive to reverse, Grease visible on inside of wheel or driveshaft boot torn
Fix: Front CV joints and U-joints on the front driveshaft wear out, especially if 4WD is used regularly. Entire driveshaft typically replaced rather than rebuilding joints. 2-3 hours labor.
Estimated cost: $600-1,000
Exhaust Manifold Cracking (3.7L and 4.7L)
Occasional · low severity
Typical onset: 90,000-150,000 mi
Symptoms: Ticking or tapping noise from engine bay that increases with RPM, Exhaust leak smell in cabin with heat on, Visible cracks in manifold (typically between ports), Check engine light with air/fuel ratio codes
Fix: Cast iron manifolds crack due to heat cycling, most commonly on passenger side. Requires manifold replacement and new gaskets. Rusted studs often break, requiring drilling/tapping. 4-6 hours per side.
Estimated cost: $800-1,400 per side
Owner tips
Install an external transmission cooler and bypass the factory radiator cooler immediately — this single mod prevents the most expensive failure
If buying a 3.7L, budget for engine replacement or avoid entirely; the 4.7L V8 is significantly more reliable
Inspect rear suspension thoroughly — test drive should include aggressive lane changes to feel for rear-end instability
Check TIPM manufacture date (stamped on unit under hood) — 2007-2009 production units have highest failure rate
Perform transmission fluid and filter service every 30,000 miles regardless of 'lifetime fill' claims
Buy only with a 4.7L or 5.7L engine and proof of external trans cooler install, or budget $5,000-8,000 for likely catastrophic repairs within the first year — the 3.7L is a ticking time bomb.

Chrysler Group LLC (Chrysler) is recalling certain model year 2008 Chrysler 300 vehicles manufactured May 31, 2007, to May 12, 2008, Dodge Magnum vehicles manufactured May 23, 2007, to May 12, 2008, Dodge Charger vehicles manufactured May 24, 2007, to May 12, 2008, Jeep Commander vehicles manufactured April 3, 2007, to May 12, 2008, and Jeep Grand Cherokee vehicles manufactured March 21, 2007, to May 12, 2008. In the affected vehicles, the ignition key (FOBIK) may not return to the "ON" position after being rotated to the "START" position, instead sticking between the two positions. Potentially, while the vehicle is being driven, the ignition may inadvertently move through the "RUN" position to the "ACCESSORY" or "OFF" ignition position, turning off the engine.
Consequence: If the ignition stays between "START" and "ON" positions it could cause loss of certain electrical functions. If the ignition key inadvertently moves into the "OFF" or "ACCESSORY" position, the engine will turn off, which will then depower various key safety systems including but not limited to air bags, power steering, and power braking. Loss of functionality of these systems may increase the risk of crash and/or increase the risk of injury in the event of a crash.
Remedy: Chrysler will notify owners, and dealers will replace the ignition switch and key FOBs, free of charge. The recall began August 19, 2015. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is P57.
POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE) · 13V175000
2013-05-07
Chrysler Group LLC (Chrysler) is recalling certain model year 2005-2010 Jeep Grand Cherokee vehicles manufactured February 11, 2004, through March 9, 2010; and 2006-2010 Jeep Commander vehicles manufactured January 31, 2005, through March 10, 2010. A transfer case electrical failure may result in an unintentional shifting of the transfer case into the neutral position.
Consequence: If the vehicle shifts into neutral, it may roll away increasing the risk of a crash or personal injury.
Remedy: Chrysler will notify owners, and dealers will reflash the final drive controller which governs the transfer case, with new software, free of charge. The recall began on August 15, 2013. Owners may contact Chrysler at 1-800-247-9753. Chrysler's recall campaign number is N23.
