The 1999 Acura CL shares Honda Accord underpinnings but suffers from catastrophic automatic transmission failures (V6 models especially) and serious engine problems on higher-mileage examples. The 2.3L I4 is more reliable than the troublesome 3.0L V6.
Automatic Transmission Failure (V6 models)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Harsh shifting or slipping between 2nd and 3rd gear, Flaring RPMs during acceleration, Transmission shudder or complete loss of drive, Burnt transmission fluid smell
Fix: Honda's 4-speed automatic (same as Accord V6) has design flaws in the pressure control solenoids and insufficient oil cooling. Requires full transmission rebuild or replacement. 8-12 labor hours for R&R plus rebuild time. Aftermarket cooler installation recommended during repair.
Estimated cost: $2,800-4,500
Engine Block Cracking and Piston Ring Failure (3.0L V6)
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Excessive oil consumption (1 qt per 500-1000 miles), Blue smoke on startup or acceleration, Coolant mixing with oil (milky dipstick), Rough idle and misfires
Fix: The J30A1 V6 develops piston ring wear and occasionally cracks cylinder walls or head gaskets. Ring job requires 18-22 hours; short block replacement 24-30 hours. Many shops recommend used engine swap as more economical.
Estimated cost: $3,500-6,500
Ignition Switch Failure (NHTSA Recall)
Common · high severitySymptoms: Intermittent no-start condition, Dashboard lights flickering or dying while driving, Complete electrical shutdown at any time, Key won't turn or gets stuck
Fix: Factory recall 00V276000 addresses overheating ignition switch that can fail without warning. Even post-recall, these switches continue to fail. Replacement takes 1.5-2 hours including steering column disassembly. Critical safety issue.
Estimated cost: $250-450
Transmission Oil Cooler Line Corrosion
Common · medium severityTypical onset: 90,000-140,000 mi
Symptoms: ATF dripping from radiator area, Pink or red fluid under vehicle, Low transmission fluid warnings, Transmission overheating
Fix: Steel cooler lines rust through where they route near the subframe. Replacement requires 2-3 hours and both pressure and return lines should be replaced together. Inspect during every transmission service.
Estimated cost: $350-600
Engine and Transmission Mount Deterioration
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: Clunking on acceleration or deceleration, Excessive vibration at idle, Engine rocking visible under hood during gear changes, Transmission shifter vibration
Fix: Hydraulic mounts collapse, especially the front and rear engine mounts and the front transmission mount. Replace all three for best results, 3-4 hours total. Use OEM Honda/Acura parts—aftermarket mounts fail quickly.
Estimated cost: $450-750
Power Steering Pump Whine and Leak
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: High-pitched whine when turning at low speeds, Steering feels heavy intermittently, PS fluid leak from pump seal, Groaning noise when stationary with wheel turned
Fix: Pump shaft seal leaks and internal vanes wear. Replacement pump required (rebuilds don't last). 2-3 hours labor. Flush system completely to prevent contaminating new pump.
Estimated cost: $400-650
Airbag SRS Light and Driver Inflator Recall
Occasional · high severitySymptoms: SRS warning light illuminated, Airbag may not deploy in crash, Takata inflator explosive degradation risk
Fix: Part of multi-year Takata recall (check VIN at NHTSA). Driver airbag inflator replacement takes 1 hour. Separately, cable reel connectors under steering wheel corrode causing SRS light—clean or replace clockspring, 1.5 hours.
Estimated cost: $0-300
Buy only if it's a 4-cylinder manual under 100k miles with impeccable service records; avoid all V6 automatics unless you're prepared for a $4k transmission job.
