The 1998 Acura CL is a front-wheel-drive coupe that shares its platform with the Accord but suffers from transmission fragility (V6 models especially) and Honda's notorious automatic transmission failures of this era. The 2.2L I4 is more reliable mechanically, but both engines share ignition switch and lower ball joint weaknesses.
Automatic Transmission Failure (V6 models)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: harsh or delayed 2-3 shifts, slipping between gears under light throttle, whining noise in 2nd or 3rd gear, Check Engine light with P0730 or P0740 codes
Fix: Honda's 4-speed automatic behind the 3.0L V6 eats itself due to inadequate cooling and weak clutch packs. Requires full rebuild or remanufactured unit (8-12 labor hours). External oil cooler retrofit is mandatory to prevent repeat failure. This is THE killer issue on V6 CLs.
Estimated cost: $2,800-4,200
Ignition Switch Failure
Common · high severityTypical onset: 90,000-150,000 mi
Symptoms: no crank, no start with multiple attempts needed, dash lights flicker or die during cranking, starter clicks but engine won't turn, accessories cut out intermittently while key is in ON position
Fix: Main ignition switch contacts burn out from high starter current draw. Honda issued recalls but many units outlived the recall period and fail later. Replacement requires column disassembly (2-3 hours). Use OEM Honda part—aftermarket switches fail early.
Estimated cost: $350-550
Lower Ball Joint Separation
Occasional · high severityTypical onset: 70,000-110,000 mi
Symptoms: clunking over bumps from front suspension, wandering or loose steering feel, uneven inside tire wear on front tires, visible grease leaking from ball joint boot
Fix: Front lower ball joints can separate catastrophically—recall issued but not all units caught. Inspect every alignment job. Replacement requires pressing out riveted joints and installing bolted aftermarket or OEM pieces (2.5 hours per side, alignment required).
Estimated cost: $450-700
Distributor O-Ring Oil Leak (I4 only)
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: oil pooling on top of transmission bellhousing, burning oil smell after highway driving, oil dripping onto exhaust manifold, slight oil consumption between changes
Fix: The 2.2L F-series engine has the distributor mounted at the cylinder head rear. O-ring hardens and leaks oil down the back of the block. Requires removing distributor, cleaning mating surface, new O-ring and gasket (1.5 hours). Mark rotor position before removal to preserve timing.
Estimated cost: $180-280
Transmission Mount Collapse
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: clunk when shifting from Park to Drive or Reverse, excessive engine movement visible from engine bay during acceleration, vibration at idle that smooths out above 1,500 RPM, rubbing or scraping noise on hard launches
Fix: Upper transmission mount (torque mount) deteriorates and allows powertrain to rock excessively. Often mistaken for bad motor mounts. Replacement requires supporting engine and trans, removing through-bolt (1.5-2 hours). Replace all three mounts if doing the job—they age together.
Estimated cost: $220-380
Fuel Filter Clogging and Fuel Pump Stress
Occasional · medium severityTypical onset: 100,000-140,000 mi
Symptoms: hard starting when fuel tank below 1/4, stumbling or hesitation under acceleration, loss of power at highway speeds, Check Engine light with lean codes P0171/P0174
Fix: In-tank fuel filter clogs from sediment, especially if tank has never been dropped. Restricted filter kills fuel pump prematurely. Requires dropping fuel tank for access (3-4 hours). Replace both filter and pump together—pump has already been working hard. This generation has no external serviceable filter.
Estimated cost: $550-850
Head Gasket Failure (V6 only)
Rare · high severityTypical onset: 120,000-180,000 mi
Symptoms: white smoke from exhaust on cold start, coolant loss with no visible leaks, overheating under load or in traffic, milky oil on dipstick or oil cap underside, rough idle with misfire codes
Fix: The J30A1 V6 can blow head gaskets between cylinders or into coolant passages, often due to overheating from transmission cooler line failure or neglected cooling system. Requires removing intake manifold, both heads, resurfacing, new gaskets and bolts, timing belt service while apart (18-24 hours). Often totals the car due to labor cost.
Estimated cost: $3,200-5,000
Buy the 2.2L I4 with a manual transmission if you can find one—avoid the V6 automatic unless you can verify recent transmission rebuild with added cooler, otherwise it's a $3k repair waiting to happen.
