The 2001 MDX is Honda's first-generation luxury SUV sharing the J35A3 V6 with the Odyssey—solid engine, but plagued by automatic transmission failures and torque mount issues that defined this era of Honda/Acura products.
Automatic Transmission Failure (BDGA/MGHA)
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Harsh or delayed 2nd-3rd gear shifts, Shuddering during light acceleration or coasting, Check engine light with P0730, P0740, or P0780 codes, Burnt ATF smell or dark fluid despite regular changes
Fix: This transmission has weak 2nd gear clutches and a torque converter lockup problem. Rebuild runs 18-24 hours labor, or R&R with reman unit is 12-16 hours. Many shops won't touch rebuilds anymore—expect a reman or used trans. Flushing the transmission accelerates failure; Honda specified drain-and-fill only.
Estimated cost: $3,200-5,500
Transmission Mount Failure
Common · medium severity
Typical onset: 60,000-120,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive/Reverse, Excessive vibration at idle in gear, Visible engine movement when revving in Park, Transmission tunnel heat complaints
Fix: The upper transmission mount (part #50850-S3V-A05) deteriorates and allows the trans to sag into the tunnel. 2-3 hours labor, accessed from above. While you're in there, inspect the rear engine mount and lower trans mount—often all three are shot simultaneously. OEM Honda part is mandatory; aftermarket mounts fail quickly.
Estimated cost: $350-550
VCM Pressure Switch Oil Leaks
Common · low severity
Typical onset: 100,000-180,000 mi
Symptoms: Oil seepage around rear valve cover, P1259 or P2646 VTEC system codes, Oil smell in cabin when heater is on, Low oil level without visible external leaks
Fix: The VTEC oil pressure switches on the rear head develop leaks from O-ring failure. Not a difficult job but requires removing the upper intake plenum for access—4-5 hours labor. Replace both switches and all valve cover gaskets while you're there; the rear cover gasket almost always weeps on these miles.
Estimated cost: $550-850
Front Suspension Spring Sag and Strut Failure
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Front end sits noticeably lower than rear, Clunking over bumps or turning, Uneven tire wear on inside edges, Bouncy or floaty ride quality
Fix: Factory springs lose 1-2 inches of height and struts wear out together. There was an NHTSA recall for spring breakage but many weren't replaced. Full front strut assemblies with springs is 3-4 hours labor. If springs are sagging but not broken, quick-struts (complete assemblies) are the fast fix. Alignment mandatory afterward.
Estimated cost: $800-1,400
Timing Belt Water Pump Service Neglect Consequences
Occasional · high severity
Typical onset: 105,000-210,000 mi
Symptoms: Sudden no-start after belt failure (interference engine), Coolant leak from water pump weep hole, Squealing or chirping from front of engine, Overheating or coolant loss
Fix: The J35A3 is an interference engine—if the belt snaps, you're looking at bent valves minimum, often full head work. OE interval is 105k mi/7 years, but if skipped and it fails at 150k+, expect 25-35 hours for head removal, valve work, new guides, resurface, and reassembly. Prevention is 5-6 hours for belt, water pump, tensioner, and seals.
Estimated cost: $800-1,200 (preventive) / $4,500-7,000 (repair after failure)
Power Steering Pump Whine and Leaks
Occasional · low severity
Typical onset: 120,000-180,000 mi
Symptoms: Groaning or whining when turning at low speeds, Stiff steering when cold, Power steering fluid leak from pump body or lines, Reservoir consistently low despite topping off
Fix: The pump develops internal wear and the high-pressure hose O-rings fail. Pump replacement is 2-3 hours; if doing pump, replace both hoses and flush the rack. System uses Honda-specific fluid (not universal PS fluid). Ignoring it leads to rack damage which is 6-8 hours and much pricier.
Estimated cost: $450-750
Owner tips
Change transmission fluid every 30k miles using Honda DW-1 ATF only—drain and fill method, never flush
Inspect all three motor mounts annually after 80k miles; they fail in clusters
Use Honda-branded coolant and maintain the 105k/7yr timing belt interval religiously
Check for transmission fluid leaks at the cooler lines (front of radiator)—corrosion causes pinhole leaks
Replace brake fluid every 3 years; the ABS modulator is expensive and moisture-sensitive
Buy one under 100k miles with documented transmission service or a fresh rebuild, otherwise plan $4k in immediate repairs—transmission and mounts will get you.

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.

POWER TRAIN:AUTOMATIC TRANSMISSION · 04V176000
2004-04-15
ON SOME MINI VANS, SPORT UTILITY AND PASSENGER VEHICLES, CERTAIN OPERATING CONDITIONS CAN RESULT IN HEAT BUILD-UP BETWEEN THE COUNTERSHAFT AND SECONDARY SHAFT SECOND GEARS IN THE AUTOMATIC TRANSMISSION, EVENTUALLY LEADING TO GEAR TOOTH CHIPPING OR GEAR BREAKAGE.
Consequence: GEAR FAILURE COULD RESULT IN TRANSMISSION LOCKUP, WHICH COULD RESULT IN A CRASH.
Remedy: ON VEHICLES WITH 15,000 MILES OR LESS, THE DEALER WILL UPDATE THE TRANSMISSION WITH A SIMPLE REVISION TO THE OIL COOLER RETURN LINE TO INCREASE LUBRICATION TO THE SECOND GEAR. ON VEHICLES WITH MORE THAN 15,000 MILES, THE DEALER WILL INSPECT THE TRANSMISSION TO IDENTIFY GEARS THAT HAVE ALREADY EXPERIENCED DISCOLORATION DUE TO OVERHEATING. IF DISCOLORATION EXISTS, THE TRANSMISSION WILL BE REPLACED IF DISCOLORATION IS NOT PRESENT, THE DEALER WILL PERFORM THE REVISION TO THE OIL COOLER RETURN LINE. THE RECALL BEGAN ON APRIL 21, 2004, FOR PILOT, ODYSSEY, AND MDX OWNERS. OWNERS OF THE ACCORD VEHICLES WILL START RECEIVING LETTERS ON JUNE 28, 2004, AND ON JUNE 29, 2004, FOR OWNERS OF THE TL AND CL VEHICLES. OWNERS SHOULD CONTACT HONDA AT 1-800-999-1009 OR ACURA AT 1-800-382-2238.
