The 1999 Honda Odyssey (first-gen) is notorious for catastrophic automatic transmission failures and severe engine oil consumption leading to bottom-end damage. These two issues define ownership experience and make this generation a risky used buy.
Symptoms: Harsh shifting or slipping between gears, especially 2nd-3rd, Transmission shudder during acceleration, Delayed engagement when shifting from Park to Drive, Metal shavings in fluid, burnt fluid smell, Complete loss of forward gears (stranded)
Fix: Rebuild or replacement required. Rebuilt units often fail again within 50k miles due to inherent design weakness in clutch packs and inadequate cooling. Expect 8-12 hours labor for R&R plus rebuild/reman unit. Many owners go straight to used JDM transmission.
Estimated cost: $2,500-4,200
Severe Engine Oil Consumption / Piston Ring Failure
Common · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Burning 1+ quart of oil every 500-1000 miles, Blue smoke from exhaust on startup or acceleration, Fouled spark plugs, Low oil pressure warning if driven low on oil, Rod knock if oil starvation occurs (often fatal)
Fix: Piston ring replacement requires complete engine disassembly (30-40 hours labor), but many engines also show cylinder scoring requiring overbore or short-block replacement. Most owners facing this choose used engine swap (12-16 hours) as more economical. Prevention: obsessive oil level checks every fillup.
Estimated cost: $3,500-6,500
Transmission Oil Cooler Line Corrosion and Leaks
Common · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Transmission fluid spots under vehicle, front-center area, Low transmission fluid level leading to slipping, Visible corrosion on steel cooler lines near radiator, Fluid dripping onto exhaust creating smoke/smell
Fix: Steel cooler lines rust through where they pass under engine. Requires replacement of hard lines and possibly rubber hoses. Access is difficult requiring subframe work. 3-5 hours labor. Replace both lines even if only one is leaking—the other is close behind.
Estimated cost: $400-750
Ignition Switch Failure (NHTSA Recall Issue)
Occasional · high severity
Symptoms: Key will not turn or is very difficult to turn, Intermittent no-start, all electrical dead, Engine stalls while driving (loss of power steering/brakes), Warning lights flicker or dash goes dark while driving
Fix: Faulty ignition switch assembly. Honda issued recalls but many vehicles never got the fix or switches failed post-recall. Switch replacement is straightforward: 1.5-2 hours including steering column disassembly. Critical safety issue—loss of power steering and brake boost while moving.
Estimated cost: $250-450
Engine and Transmission Mount Deterioration
Common · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Excessive vibration at idle, especially in Drive, Clunking when shifting from Park to Drive/Reverse, Engine rocks visibly under acceleration, Harsh engagement feel through chassis
Fix: Rubber mounts fail from heat and age. Front engine mount and rear transmission mount are most common. Rear trans mount requires lifting transmission slightly. 2-3 hours labor for front, 3-4 hours for rear due to access. Replace all three (left/right/rear) if doing the job to avoid comebacks.
Estimated cost: $400-800
Power Sliding Door Latch and Cable Failures
Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Door will not latch closed properly, Door open warning stays on with door closed, Manual override cable breaks leaving door stuck, Motor runs but door doesn't move
Fix: Latch mechanisms wear and cables fray. Multiple recalls issued but problems persist. Latch replacement: 2-3 hours per door. Cable replacement adds another hour. Interior trim removal required. Not a breakdown issue but annoying and reduces resale value.
Estimated cost: $350-650
Owner tips
Check transmission fluid level and color every oil change—dark/burnt fluid means you're on borrowed time
Monitor oil consumption religiously starting at 100k miles; carry extra quarts in vehicle
Flush transmission fluid every 30k miles with Honda ATF-Z1 only (not universal fluid)—may delay but not prevent failure
Inspect cooler lines annually for rust; preventive replacement at 100k saves transmission
Budget $3,000-5,000 for inevitable transmission work if buying used over 80k miles
Avoid unless you're getting it for $1,500 or less with a recently replaced transmission and documented low oil consumption—even then, expect major repairs within 30-40k miles.

AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE · 20V026000
2020-01-17 · EQ19002
Honda (American Honda Motor Co.) is recalling certain 1998 Acura 2.2CL, 1998-1999 Acura 2.3CL, 1998-1999 Acura 3.0CL, 2001 Acura 3.2CL and Acura MDX, 1998-2000 Honda Accord Coupe, Accord Sedan, Civic Sedan, Odyssey and Acura 3.5RL, 1999-2000 Acura 3.2TL, 1996-2000 Civic Coupe, 1997-2000 CR-V, 1997-1998 EV Plus, and 1998-1999 Isuzu Oasis vehicles.
These vehicles were equipped with Non-Azide Driver air bag Inflators (NADI) and do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, causing the inflators to rupture or the air bag cushion to underinflate.
Consequence: In the event of a crash necessitating air bag deployment, an inflator rupture may result in metal fragments striking the driver or other occupants. An underinflated air bag cushion may not properly protect the occupant. These scenarios increase the risk of serious injury or death.
Remedy: Honda will notify owners, and dealers will inspect the driver frontal air bag inflator, and replace it if necessary, with an inflator of a different design, free of charge. The recall began October 1, 2020. Owners may contact American Honda's Customer Support & Campaign Center at 1-888-234-2138 or Isuzu customer service at 1-800-255-6727.
