The 2014 Dart is notorious for catastrophic dual-clutch transmission failures and premature engine bearing/piston failures, particularly on the 1.4L turbo. These are expensive, platform-defining problems that often total the car economically.
Dual-Clutch Transmission (DCT) Failure - Complete Replacement Needed
Common · high severityTypical onset: 50,000-90,000 mi
Symptoms: Violent shuddering during low-speed acceleration or gear changes, Grinding noises when shifting, especially 2nd to 3rd gear, Sudden loss of power or refusal to engage gears, Burning smell from transmission, Check engine light with clutch actuator codes
Fix: The dual-clutch automated manual is the Achilles heel. Clutch pack replacement rarely fixes it long-term; most need a remanufactured transmission. 8-12 hours labor for R&R, plus programming.
Estimated cost: $3,500-5,500
1.4L Turbo Engine Bearing and Piston Failure
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: Loud knocking or rattling from engine block, especially cold start, Metal shavings in oil during changes, Sudden loss of oil pressure, Catastrophic engine seizure, Blue smoke from exhaust under acceleration
Fix: The 1.4L MultiAir suffers from bearing wear and piston ring land failure. Oil passages clog, starving bearings. Requires complete engine rebuild or replacement short block. 16-22 hours labor for full teardown/rebuild, more for short block swap.
Estimated cost: $4,500-7,000
Head Gasket Failure - 2.4L Tigershark
Occasional · high severityTypical onset: 70,000-110,000 mi
Symptoms: White smoke from exhaust on startup, Coolant loss with no visible leaks, Overheating under load, Milky oil on dipstick or oil cap, Rough idle and misfires
Fix: The 2.4L develops head gasket leaks between cylinders or into coolant passages. Both heads typically need surfacing. 14-18 hours labor, includes timing chain replacement while you're in there.
Estimated cost: $2,800-4,200
Transmission Control Module (TCM) Failure
Common · medium severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission stuck in one gear (limp mode), Erratic shifting patterns, Won't start or crank with no-start condition, Dash warning lights for transmission, Total loss of communication with TCM on scanner
Fix: TCM fails outright or develops corrupted software. Replacement module requires programming to VIN and adaptive learning drive cycle. 2-3 hours labor plus module cost.
Estimated cost: $800-1,400
Transmission Oil Cooler Leaks and Clogging
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Pink fluid pooling under vehicle (transmission fluid in coolant), Transmission overheating warnings, Milky appearance in coolant reservoir, Harsh or delayed shifts after warmup, Coolant in transmission pan during service
Fix: Internal transmission cooler in radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, transmission fluid flush (often multiple flushes), and sometimes transmission rebuild if contamination caused damage. 4-6 hours labor if caught early.
Estimated cost: $900-2,200
Vacuum Brake Booster Failure
Occasional · high severitySymptoms: Hard brake pedal requiring excessive force, Hissing sound when pressing brakes, Engine stalling when braking, Brake pedal sinks slowly to floor when held at stop, Check engine light with lean codes from vacuum leak
Fix: Booster diaphragm ruptures, creating vacuum leak and losing power assist. Recall issued but not all units covered. 3-4 hours labor for booster replacement.
Estimated cost: $600-1,100
Shifter Cable and Linkage Detachment
Occasional · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Shifter moves freely with no gear engagement, Can't shift out of park, Gear indicator doesn't match actual gear, Shifter feels loose or disconnected, Vehicle rolls in park position
Fix: Shifter cable bushing breaks or cable detaches at transmission. Recall issued for some units. Cable replacement takes 2-3 hours including console disassembly.
Estimated cost: $350-700
Hard pass unless you're getting it for $2,000 or less and consider it disposable transportation - the transmission and engine issues make this one of the least reliable vehicles of the 2010s.
