The 2009 Ram 1500 is a solid truck platform with two major Achilles heels: the 545RFE/65RFE transmission runs hot and fails prematurely, and the 5.7L Hemi suffers catastrophic cam/lifter failures due to the Multi-Displacement System (MDS). The 4.7L is more reliable but underpowered for heavy towing.
Transmission Overheating and Failure (545RFE/65RFE)
Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Delayed or harsh shifting, especially 2nd to 3rd gear, Transmission slipping under load or on hills, Burnt ATF smell, dark or metallic fluid, Check engine light with P0841 or P0846 codes, Complete loss of forward gears
Fix: Root cause is inadequate factory trans cooler. Transmission oil cooler lines leak at crimped fittings, starving the trans of fluid. Full rebuild or replacement required once damage occurs (12-16 hours labor). Prevention: install aftermarket auxiliary trans cooler and inspect lines annually.
Estimated cost: $2,800-4,200
Hemi MDS Cam and Lifter Failure
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Ticking or tapping noise from engine, worse on cold start, Check engine light with multiple misfire codes, Loss of power, rough idle, Metal shavings in oil, low oil pressure warning, Catastrophic engine failure if driven after noise starts
Fix: MDS lifters collapse due to oil starvation, wiping cam lobes. Requires camshaft replacement, all 16 lifters, pushrods inspection, and often cylinder head work if debris circulated (20-28 hours labor). Some techs delete MDS system during repair. Catch it early or face full engine rebuild.
Estimated cost: $3,500-6,500
Rear Differential Pinion Bearing Failure
Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Howling or whining noise from rear, speed-dependent, Grinding or clunking on acceleration, Vibration through drivetrain, Gear oil leaking from pinion seal, Complete axle lockup in severe cases
Fix: Factory pinion bearings wear prematurely, especially on trucks used for towing. Requires differential rebuild with new bearings, seals, and gear pattern setup (6-8 hours labor). Two NHTSA recalls related to differential issues. Check for axial play at pinion flange during inspection.
Estimated cost: $1,200-1,900
Exhaust Manifold Bolts Breaking (4.7L and 5.7L)
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Ticking or tapping noise from engine that increases with RPM, Exhaust leak smell in cabin, Visible gap between manifold and cylinder head, Failed emissions test due to leak before O2 sensor
Fix: Manifold bolts corrode and snap off due to heat cycling. Requires drilling out broken bolts, retapping holes, often with time-sert inserts. Both manifolds typically need attention at once (5-8 hours labor per side if extractions go smoothly, more if heads damaged). Use OEM-quality bolts and anti-seize on reinstall.
Estimated cost: $800-1,600
TIPM Electrical Gremlins (Totally Integrated Power Module)
Occasional · medium severity
Symptoms: Fuel pump runs continuously with key off, draining battery, Intermittent no-start condition, Wipers or windows operating on their own, ABS/traction control lights with no codes, Horn honking randomly
Fix: TIPM controls most electrical functions and fails due to internal relay corrosion or circuit board cracks. Dealer-only part, requires programming (2-3 hours labor). Many owners try resoldering relays or buying refurbished units to save money, with mixed results. Dodge extended warranty on some model years but not 2009.
Estimated cost: $900-1,400
Ball Joints Wearing Prematurely
Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Clunking noise over bumps from front end, Wandering or loose steering feel, Uneven tire wear on inside or outside edges, Visible play when prying on suspension, Steering wheel vibration at highway speeds
Fix: Upper and lower ball joints wear faster than competitors due to soft factory design. Most techs replace all four at once to avoid comebacks (4-6 hours labor). Some aftermarket options offer greaseable joints. Alignment required after replacement. Inspecting every 30k miles catches this before it becomes dangerous.
Estimated cost: $700-1,200
Owner tips
Install an auxiliary transmission cooler immediately if towing — the factory cooler is undersized and will kill your transmission
Run quality synthetic oil (5W-20) and change every 5,000 miles maximum to extend MDS lifter life on the Hemi
Inspect transmission cooler lines at every oil change for seepage at crimped fittings — replace at first sign of wetness
Check rear differential fluid every 30k miles and replace if metallic or burnt smelling — catches bearing failure early
Avoid extended idling and short trips on Hemi engines — they need operating temperature to keep MDS system lubricated
Buy only if you find one with documented transmission cooler upgrade and recent oil analysis showing clean Hemi internals — otherwise budget $3-5k for eventual major repairs within 20k miles.

Chrysler is recalling certain model year 2009-2012 Ram 1500 trucks manufactured from February 27, 2008, through June 30, 2009, and from December 1, 2009, through October 20, 2011; model year 2009-2011 Dodge Dakota trucks manufactured from February 27, 2007, through June 30, 2009, and from December 1, 2009, through September 30, 2011; model year 2009 Chrysler Aspen trucks manufactured from January 3, 2008, through December 18, 2008; and model year 2009 Dodge Durango trucks manufactured from January 3, 2008, through December 18, 2008. The rear axle pinion nut may loosen due to an undersized pinion spline that can allow relative motion between the nut and companion flange.
Consequence: If the rear axle pinion nut loosens, the axle can lock up and cause a loss of vehicle control and/or a vehicle crash with little warning.
Remedy: On November 7, 2013 Chrysler notified owners that dealers would install a pinion nut retainer, free of charge. In July 2015, and under a consent order with NHTSA, the company agreed to offer owners three options for remedying their vehicles: perform the original remedy, offer to repurchase the vehicle at the fair market value plus 10%, or offer an additional incentive offer towards the purchase of a new Dodge, Jeep, Chrysler, or Fiat vehicle. Chrysler will notify owners of the new recall options in a letter expected to be mailed on August 31, 2015. Owners may contact Chrysler at 1-800-247-9753. Chrysler's recall campaign number is N08.
