The 1999 Eclipse is a fun platform hampered by weak automatic transmissions, premature crankshaft wear (especially turbos), and common suspension wear. The 2.4L non-turbo is more reliable, but all variants suffer from deteriorating control arm bushings and persistent electrical gremlins.
Crankshaft Walk (2.0L Turbo)
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: grinding noise from front of engine, clutch engagement issues, oil leaks at front main seal, eventually won't start or runs rough
Fix: Crankshaft thrust bearing failure allows crank to move fore/aft. Requires engine removal, full teardown, crankshaft replacement or machining, new bearings, seals. 20-30 hours labor. Many opt for short block swap instead.
Estimated cost: $3,500-6,000
Automatic Transmission Failure (F4A33)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: slipping between gears especially 2nd-3rd, delayed engagement when cold, shuddering on acceleration, no forward movement
Fix: Weak clutch packs and inadequate cooling lead to internal failure. Rebuild requires 12-16 hours; most shops recommend reman unit. Oil cooler should always be replaced simultaneously to prevent repeat failure.
Estimated cost: $2,200-3,800
Lower Ball Joint Separation
Occasional · high severityTypical onset: 70,000-110,000 mi
Symptoms: clunking over bumps, wandering steering, uneven tire wear, visible grease boot tears
Fix: NHTSA recall addressed some units but failure still occurs. Ball joint can separate from control arm causing loss of steering control. Both lower control arms typically replaced as assemblies. 3-4 hours labor plus alignment.
Estimated cost: $600-900
Head Gasket Failure (2.4L I4)
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: white smoke from exhaust, coolant loss with no visible leaks, milky oil, overheating, rough idle when warm
Fix: The 4G64 engine develops head gasket leaks between cylinders or into coolant passages. Requires head removal, resurfacing, new gasket set, timing belt while it's apart. 10-14 hours labor.
Estimated cost: $1,400-2,200
Fuel Pump Failure
Common · medium severityTypical onset: 90,000-140,000 mi
Symptoms: no-start condition, sputtering under load, stalling when hot, whining noise from rear tank area
Fix: In-tank pump fails, often without warning. Tank must be dropped for replacement. Some models subject to recall but many fail outside recall scope. 2-3 hours labor.
Estimated cost: $400-700
Headlight Wiring Harness Melting
Common · medium severitySymptoms: headlights flickering or dim, burnt plastic smell near headlights, one or both headlights intermittent, melted connector housing visible
Fix: Factory headlight connectors undersized for current draw, especially with aftermarket bulbs. Wiring harness melts at connector. Proper fix is relay harness upgrade plus new OEM connectors. 2-3 hours labor if done right.
Estimated cost: $250-450
Rear Trailing Arm Bushing Deterioration
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: clunking from rear over bumps, rear end feels loose or unstable, uneven rear tire wear, visible cracking in rubber bushings
Fix: Rubber bushings in rear trailing arms crack and separate. Both sides typically need replacement. Arms must be pressed out or complete arm assemblies replaced. 4-5 hours labor plus alignment.
Estimated cost: $500-800
Buy a manual-transmission 2.4L non-turbo if you must, but even then plan for suspension work and electrical issues—turbo automatics are grenades.
