According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1991 Acura Legend has 2 documented known issues, with 1 rated critical. The most serious is Timing belt must be replaced at 90,000 mi / 72 months — interference engine eats valves if it snaps ($600-$2,000 repair). Across all issues, repair costs range from $600 to $2,000. DIY maintenance guides at au7o.io.
On the 1990-1995 Acura Legend, 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 Most original belts have been replaced by now, but second and third belts (60-90k after the first replacement) are commonly skipped because owners assume 'it's been done.'
Common Symptoms
Visible cracking or fraying on the timing belt when inspected
Squealing or rumbling from the front of the engine (tensioner bearing failing)
Oil leak from front of engine soaking the timing cover (failed crank or cam seal)
Engine starts and runs, then suddenly dies and won't restart (belt has snapped)
Loud metallic clatter on a no-start attempt (valves striking pistons)
How to Fix
Replace the timing belt every 90,000 miles OR 72 months — and treat the 72-month limit as the binding one on cars over 15 years old, regardless of mileage. The job is a full front-of-engine teardown: remove crank pulley, front cover, all accessory belts. While you're in there, ALWAYS replace the water pump, timing belt tensioner, all front seals (crank, cam, balance shaft), and idler pulley as a kit — the labor to replace any one of them later is 90% of the timing belt labor. Use OEM Mitsuboshi/Bando belts from Acura or top-tier aftermarket (Aisin, Gates Powergrip). Expect $600-1,000 in parts and $500-900 in labor at an independent. Skip the dealer ($1,500-2,000+) unless they're running a special.

TipALWAYS replace water pump + tensioner + front seals at the same time as the belt. Labor to do any one of those later equals 90% of the timing belt labor.
UpgradeAisin makes a complete Acura V6 timing kit (belt, tensioner, water pump, seals) under their TKH-series. One purchase covers everything you need. (Aisin Acura V6 Timing Belt Kit (complete))
NoteOn a 30+ year old Legend, ignore the mileage and look at the calendar. If the belt is older than 6 years, replace it — rubber degrades regardless of miles. A 'low mileage' Legend with an unknown belt history is one trip away from a $5,000 valve job.

On the 1991-1995 Acura Legend 3.2L V6 C32A, acura issued technical service bulletin TSB 95-020 covering 1991-1995 second-generation Legends for a fan control unit with defective solder joints. Sources differ on the exact physical location — some place the unit under the passenger seat, others under the passenger floorboard carpet, others above the gas pedal. There may be two related units in different locations on different production runs. The fault: solder joints on a couple of critical traces on the control board crack with heat cycling. Initial symptom is intermittent A/C operation — works one trip, doesn't the next, sometimes recovers after the car sits. As the solder fully fails, the compressor stops engaging entirely. Owners and shops chase the wrong rabbit hole (low refrigerant, dead clutch coil, blown fuse) — but the actual fault is a cracked solder joint inside a control module that costs $0.05 in solder to fix.
Common Symptoms
A/C compressor engages intermittently — works some days, not others
A/C works when cold-start, fails after car warms up (or vice versa)
Tapping the passenger floor area sometimes temporarily restores A/C
Eventually compressor stops engaging entirely
Refrigerant pressure is correct, compressor clutch coil tests good, but no engagement
Replacing the compressor doesn't fix the problem
How to Fix
Pull back the passenger-side front carpet (slide passenger seat fully back, lift carpet edge from the door sill, fold forward). The fan control unit is a black box screwed to the floor — unplug the connectors and remove. Inspection with a magnifier shows the cracked solder joints on the trace(s) for compressor relay control. Re-flow the joints with a soldering iron and a small amount of fresh solder. Total cost: $0 in parts, 1 hour of labor. Replacement units are scarce and expensive ($150-300 used) so the solder-repair is the standard fix. Acura specialists and Honda forums have documented the exact joints — search 'Acura Legend fan control unit solder' for board photos showing the failure points.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
TipBefore you spend $400-800 on a new compressor, pull the passenger carpet and inspect the fan control unit board. A 1-hour solder re-flow with a $20 iron fixes most 'compressor not engaging' issues on 1991-1993 Legends.
NoteDon't let a shop sell you a replacement compressor without first checking the fan control unit. The TSB is well-known to Acura specialists but commonly missed by generic A/C shops.
TipReplacement fan control units are scarce — $150-300 used on eBay. Re-soldering the original board is the standard durable fix, and many Honda specialists publish board photos showing the exact failure points.
