The failure pattern owners describe
Engine stalling is the dominant complaint across 129 reports, with owners describing sudden shutdown at stop lights, stop signs, turns, and low speeds—often without check-engine codes or warning. When the engine cuts out, power steering and brakes vanish, leaving the truck adrift in traffic. One owner stalled at an intersection with his mother aboard and had to immediately restart to avoid collision. Restarts happen normally, but the stalling recurs unpredictably. Dealers struggle to diagnose because the intermittent nature means no codes set, and test drives don't trigger failure.
EGR valve failure stands out as a repeated culprit—codes P0404, P0405, P0406—with multiple owners replacing the valve only to have it fail again within a year. Dodge service departments acknowledge this is a common design flaw, yet it's not recalled. Crank position sensors also fail repeatedly; one owner replaced three in two years and 20,000 miles.
Beyond stalling, owners report plastic valve covers cracking and causing 60+ back-order situations at dealerships, drive shafts separating at highway speed, timing chain tensioners breaking, engines locking up from sludge, and rear axles seizing. One owner's truck developed a carbon monoxide leak into the cab. Warranty denial is common when codes don't appear or maintenance records are disputed. The recurring theme: dealers cannot fix what they cannot replicate, and Dodge has issued no effective recalls despite overwhelming evidence of systemic problems.

Failure modes owners describe
Engine stalling at low speeds and stops
Engine shuts off without warning at stop lights, stop signs, while turning, or when slowing to a stop. Power steering and brakes are lost. Stalling occurs intermittently, often without triggering diagnostic codes. Owners report the truck restarts normally after stalling.
When: Low speeds (under 40 mph), at stops, during turns, cold starts, within first 6 months to several years of ownership
Symptoms owners cite: Engine cuts off without warning; Loss of power steering and power brakes; No check engine light or intermittent check engine light; May stall multiple times during short trip; Hesitation before stalling; RPM drop when shifting into gear from park or reverse
Codes mentioned: P0404, P0405, P0406, P0115
Repairs/costs cited: Dealers have replaced: transmission filter, crank position sensor (multiple times), EGR valve, throttle body, idle air control motor, PCM flash, thermostat, ECT sensor, camshaft sensor, ignition switch module. Many repairs provide temporary relief or no relief. Owners report spending $300–$400+ per diagnostic visit.
Recalls/TSBs owners mention: TSB 18-013-05 issued as attempted fix for crank sensor issue; owners report it was unsuccessful. Dealers unable to duplicate problem or find codes; unable to perform repair under warranty once owner mileage exceeded limits or codes not present. One dealer mentioned seeing problem on other vehicles but did not know how to fix it.
EGR valve sticking or failure
Exhaust gas recirculation (EGR) valve sticks open or fails, causing engine to run lean and stall. Owners report this is a known design flaw with high failure rate. Valve typically should not fail within four years.
When: First 6 months to 4+ years of ownership; approximately 12,000 to 160,750 miles
Symptoms owners cite: Stalling at low speeds and stops; Check engine light with codes P0404, P0405, or P0406; Rough idle; Loss of power and acceleration; RPM surging
Codes mentioned: P0404, P0405, P0406
Repairs/costs cited: EGR valve replacement costs vary; owners report dealers and parts stores have difficulty obtaining the part and it is backordered at multiple dealerships (60+ back orders noted at single locations). One owner reported replacing the valve only to have the problem recur within a year.
Recalls/TSBs owners mention: Dodge service departments confirm this is a common problem but state the warranty does not cover it or it is a design flaw not eligible for recall.
Crank position sensor failure
Crankshaft position sensor fails or provides faulty signal, causing intermittent stalling, rough running, and no-start conditions. Owners report replacing the sensor 2–3 times in less than 2 years and 20,000 miles.
When: Early in ownership (2,500 miles) to high mileage (160,750 miles); sensors replaced repeatedly
Symptoms owners cite: Intermittent stalling; Difficulty starting; Check engine light on or off intermittently; Engine runs rough
Codes mentioned: Crank sensor fault
Repairs/costs cited: Sensor replacement $100–$385 per visit; owners report needing 3 replacements in 2 years. Wiring tested good; wheel teeth not broken or worn; no buildup of shavings.
Recalls/TSBs owners mention: TSB 18-013-05 issued; owner states it has not been successful as issue re-occurs at faster rate each time.
Plastic valve cover cracking or failure
Plastic valve cover develops hole or cracks, causing oil leakage. Multiple dealerships reported over 60 back orders for this single part at one location, suggesting widespread failure. Owner suspects cover blew due to internal pressure and caused overheating.
When: July 2015 (one reported incident at that time)
Symptoms owners cite: Visible hole in right-side valve cover; Oil leakage
Repairs/costs cited: Replacement cost significant; part must be ordered from Dodge dealership and is not available from aftermarket parts stores. Extensive back-order situation noted (60+ at one dealership, 120+ across two surveyed locations).
Engine sludge buildup and premature failure
Engine develops internal sludge buildup resulting in complete engine failure and lock-up. Owners report no prior warning and sudden loss of power while driving. One case involved denial of warranty coverage despite claimed regular oil changes.
When: 24,000 to 113,000 miles
Symptoms owners cite: Oil indicator fluctuating wildly; Sudden engine shutdown while driving at highway speed; Engine smoking; Fluid leaking from engine; No power under acceleration; Knocking sound from engine
Repairs/costs cited: Complete engine replacement required; costs range from $6,000 to $10,000 including labor. Mechanics could not explain cause; no mechanical parts found to be defective.
Recalls/TSBs owners mention: Warranty denied in one case due to claimed sludge in oil, despite owner dispute over maintenance history.
Drive shaft failure and separation
Drive shaft pin backs out and enters rear differential, causing spider gears to lock up. Drive shaft then tears away from rear axle and separates into two pieces while vehicle is in motion. Vehicle appears to continue running but cannot be controlled.
When: Approximately 6 p.m., June 22, 2014 at 35–40 mph; original owner had maintained truck in excellent condition with no prior mechanical issues
Symptoms owners cite: Sound like blowout followed by whining and banging; Drive shaft pieces fly out from under vehicle; Rear end locks up; Complete loss of vehicle control
Repairs/costs cited: Drive shaft required complete replacement; repair center confirmed they had seen this same issue before.
Timing chain tensioner failure
Timing chain tensioner breaks at highway speed, causing engine to stall with no steering or braking control. Tensioner and timing chain pieces found in oil pan after failure. Same motor issue reported in Dodge Challenger and Charger with recalls; unclear why truck with same motor not recalled.
When: Highway speed during normal operation
Symptoms owners cite: Engine stalls at highway speed; No power steering or brakes; Possible internal engine damage
Repairs/costs cited: Owner paid out of pocket for faulty tensioner repair; concerned about additional internal damage caused by failure.
Dipstick handle breaking and removal difficulty
Plastic handle of oil dipstick breaks off during normal use (pulled only 12 times), requiring extraction of broken handle and replacement of entire dipstick at high cost.
When: During routine oil change
Symptoms owners cite: Plastic dipstick handle breaks off
Repairs/costs cited: Replacement cost $400 for part extraction and new dipstick. Aftermarket parts stores do not stock this part; must order through Dodge dealership.
Carbon monoxide intrusion into cab
Carbon monoxide detected inside cab at alarm level. Owner experienced headaches that started after purchase and purchased CO tester after becoming ill during extended drive.
When: Ongoing since purchase
Symptoms owners cite: Headaches; Nausea and sickness on extended drives; CO alarm triggered multiple times when tester placed in cab
Rear axle seizure and component failure
Rear wheels seized while driving at low speed, brake and ABS warning lights illuminated, and tail pipe disengaged from vehicle. Dealership diagnosis indicated rear axle required replacement.
When: Approximately 116,240 miles
Symptoms owners cite: Rear wheels seize; Brake and ABS warning lights illuminate; Tail pipe disengages
Repairs/costs cited: Rear axle replacement required; repair not completed due to unavailable parts.
Recalls/TSBs owners mention: NHTSA Campaign 14V796000 (Powertrain) issued but repair part unavailable; manufacturer exceeded reasonable time for recall repair.
PVC return system oil intrusion and defrost failure
In below-zero temperatures, PVC return system causes oil to squirt into engine, clogging defrost system and leaving oil residue on windshield. Occupants experienced eye burning, stomach pain, and choking.
When: Below zero temperature driving at 65 mph
Symptoms owners cite: Oil residue on windshield; Defrost system failure; Eye irritation and burning; Stomach pain; Choking sensation
Repairs/costs cited: Repair cost approximately $400 when parts arrive.
Recalls/TSBs owners mention: Manufacturer stated there was no mechanical failure, no parts available, and advised contact to drive only in temperatures above zero degrees.
Engine hesitation and loss of power while merging
