According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1990 Acura Legend has 1 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 Most original belts have been replaced by now, but second and third belts (60-90k after the first replacement) are commonly skipped because owners assume 'it's been done.'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.
