The 1998 Acura TL is a solid mid-size luxury sedan, but the automatic transmission is a notorious weak point that can fail catastrophically, particularly in V6 models. Engine issues are less common but can be expensive when internal components fail.
Automatic Transmission Failure
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: Harsh shifting or slipping between gears, especially 2nd to 3rd, Shuddering during acceleration, Delayed engagement when shifting to Drive or Reverse, Transmission warning light or flashing D4 indicator, Complete loss of forward gears
Fix: Requires transmission rebuild or replacement. Factory transmissions had inadequate cooling and weak clutch packs. Rebuild takes 8-12 hours; many shops recommend remanufactured unit with upgraded components. External oil cooler addition recommended.
Estimated cost: $2,500-4,500
Lower Ball Joint Wear and Separation
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Clunking noise over bumps from front suspension, Wandering or unstable steering, Uneven tire wear on inside edge, Excessive play when shaking wheel at 6 and 12 o'clock
Fix: Ball joints are pressed into control arms; most shops replace entire lower control arm assembly per side. NHTSA recall addressed some VINs but not all. 2-3 hours per side for control arm replacement, alignment required after.
Estimated cost: $400-700
Transmission Mounts Collapse
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking when shifting from Park to Drive, Excessive vibration at idle, especially with A/C on, Engine rocking visible under hood during acceleration, Roughness smooths out above 1500 RPM
Fix: Hydraulic transmission mount wears and leaks fluid, allowing excessive drivetrain movement. Replacement is straightforward but requires supporting engine/transmission. 1.5-2 hours labor.
Estimated cost: $250-400
Head Gasket Failure (3.2L V6)
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Overheating or fluctuating temperature gauge, Milky oil on dipstick or oil cap, Bubbles in coolant reservoir when running
Fix: C32A1 engine can develop head gasket leaks, often between cylinders or into coolant passages. Requires cylinder head removal both sides, machining check, new gaskets, timing belt service while in there. 14-18 hours labor. Often find warped heads requiring machine work.
Estimated cost: $2,800-4,200
Power Steering Pump and Rack Leaks
Occasional · medium severityTypical onset: 90,000-140,000 mi
Symptoms: Groaning or whining noise when turning, especially when cold, Puddles of reddish fluid under front of car, Heavy steering at low speeds, Power steering fluid level drops frequently
Fix: Pump seals deteriorate and rack end seals leak. Pump replacement is 2-3 hours; rack replacement is 4-6 hours including alignment. Often both are weeping by 130k miles. Address pump first as failing pump can damage rack.
Estimated cost: $600-900 pump, $1,200-1,800 rack
Ignition Switch Failure
Occasional · medium severitySymptoms: Accessories cut out while driving (radio, gauges go dead), Intermittent no-start with no clicks or cranking, Key hard to turn or gets stuck in ignition, Dash lights flicker when wiggling key
Fix: Ignition switch contacts wear internally. Part is in steering column, requires airbag/wheel removal and column disassembly. 2.5-3.5 hours. Different from the key cylinder; this is the electrical switch behind it.
Estimated cost: $350-550
Buy the 1998 TL only if the transmission has already been rebuilt with upgrades or you're prepared to budget $3,000-4,000 for inevitable transmission work—everything else is manageable.
