1990-1995 Acura Legend Problems: 8 Known Issues

The 3.2L C32A/C32A1 V6 (1991-1995 Acura Legend) uses an open-deck block with a graphite (not multi-layer steel) head gasket. Engine vibration concentrated at the rear of the block wears through the gasket between the unsupported cylinder tops and the deck surface, almost always failing at cylinders #3 and #6 (cylinder #6 is the most failure-prone). Coolant enters the cylinders causing white exhaust smoke, coolant loss, misfires, and eventually hydrolock. The Type-II C32A1 (1993-1995 coupe LS/L, 1994-1995 GS sedan), especially with the 6-speed manual, sees accelerated failure due to higher loads.

The Legend's C27A (1990) and C32A (1991-1995) V6s are both interference engines: the valves and pistons share the same vertical space at different points in the rotation, separated only by precise timing belt synchronization. If the belt fails — from age (rubber breakdown), tensioner failure, or contamination by leaking front-engine oil seals — the camshafts stop while the crankshaft keeps spinning, and valves slam into pistons. Result: bent valves, often damaged guides, sometimes a cracked piston, and a repair bill that exceeds the car's value. Honda's published interval is 90,000 miles or 72 months, whichever comes first — and on 30+ year-old Legends 'whichever comes first' is almost always the calendar. Most original belts have been replaced by now, but second and third belts (60-90k after the first replacement) are commonly skipped because owners assume 'it's been done.'

Both valve cover gaskets and the six rubber spark-plug tube seals harden and shrink with age, leaking oil down the engine and into the spark plug wells. Oil pooling in the plug wells causes misfires and damaged coil/wire boots. The driver-side bank is significantly harder to access on the G2 Legend's longitudinal V6 — bolts near the automatic transmission fluid dipstick make DIY replacement a multi-hour job on that side. Common at 80k+ miles on any G2 Legend.

The radiator/condenser fan control unit, located under the passenger floor carpet, suffers cracked solder joints on its circuit board from heat cycling. Symptoms include rad fans not coming on (causing overheating at idle), fans running at full speed at every startup, A/C clutch engaging with the switch off, or random fan/AC behavior. Honda/Acura Service News B98-05-00 (May 1998, 'Fan Control Unit Causes Warm A/C') documents diagnosis; the defect is widely reported on 1991-1992 units and some 1993 units.

The Sumitomo ALB (Anti-Lock Brake) system on G2 Legends uses a high-pressure hydraulic pump and nitrogen-charged accumulator in the right front engine bay. The pump motor brushes wear out causing the pump to run more than 2 minutes continuously (ABS Code 1), and the accumulator loses nitrogen charge over time. Result is ABS light on, pulsing pedal at low speed, or noisy continuous pump operation after engine start.

The PGM-FI main relay (under the dash, driver's side near the fuse box) controls power to the ECU and fuel pump. PCB solder joints develop hairline cracks from vibration and heat cycling. On hot days (90F+) or after a hot soak in the sun, the cracked joints open and the car cranks but will not start until it cools 5-15 minutes. Same failure mode as virtually every 1988-2000 Honda/Acura.

The PS high-pressure hose deteriorates internally from age, heat, and the constant 1,000+ psi pressure. Two failure modes: external leak at the crimp where the hose meets the pump fitting (rapid fluid loss requiring top-up every 5-10 miles), and internal rubber slough that darkens the fluid and clogs the rack ports, valves, and pump check valves. Common at 100k+ miles on all G2 Legends.

Each sunroof corner has a small drain tube routing through the A-pillars (front) and down through the quarter panels to outlets behind the rear wheel wells (rear). The tubes clog with debris or split with age (rubber becomes brittle), allowing rainwater to overflow into the cabin. Front clogs flood the driver/passenger footwell carpet; rear clogs flood the trunk spare tire well.
