In owners' own words
I just bought a 2003 Acura MDX with 110,000 miles. I drove the car less than 15 miles and noticed a scraping noise coming from the rear.
I was driving on I-75 when my transmission failed, car went from going 70MPH to dropping all rpm's and driving as if it were in neutral.
My 2003 Acura MDX showed no signs of a transmission issue until one day the transmission slipped into neutral without warning.

Recalls for the 2003 Acura MDX: 13
The rotating portion of the accelerator pedal assembly may bind. If the accelerator pedal binds, the engine may not quickly return to idle after the pedal is no longer pressed, increasing the risk of a crash.
The vehicles are equipped with passenger frontal air bag inflators assembled as a recall remedy part or replacement service part, that may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
These vehicles are equipped with driver frontal air bag inflators assembled as a recall remedy part or replacement service part, that may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Due to a manufacturing error, in the event of a crash necessitating deployment of the driver frontal air bag, these inflators may explode. An explosion of an inflator within the driver frontal air bag module may result in sharp metal fragments striking the driver, front seat passenger or other occupants resulting in serious injury or death.
These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
The affected vehicles have a passenger side frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture upon its deployment. In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the passenger seat occupant or other occupants possibly causing serious injury or death.
The affected vehicles are equipped with a dual-stage driver frontal air bag that may be susceptible to moisture intrusion and other factors, including manufacturing variability that, over time, could cause the inflator to rupture. In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.
Due to electrical noise, a component in the air bag control module may fail, causing the front air bags, side air bags, and/or seatbelt pretensioners to deploy inadvertently while the vehicle is being operated. Inadvertent deployment of the air bags may increase the risk of injury and the possibility of a vehicle crash.
Upon deployment of the passenger side frontal air bag, excessive internal pressure may cause the inflator to rupture. In the event of a crash necessitating deployment of the passenger s frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Upon deployment of the passenger side frontal air bag, excessive internal pressure may cause the inflator to rupture. In the event of a crash necessitating deployment of the passenger s frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Due to electrical noise, a component in the air bag control module may fail causing the front air bags, side curtain air bags, and/or seatbelt pretensioners to deploy inadvertently while the vehicle is being operated. Inadvertent deployment of the air bags may increase the risk of injury and the possibility of a vehicle crash.
The interlock lever of the ignition switch may deform, which can allow the interlock function of a vehicle with an automatic transmission to be defeated. Removal of the ignition key when the gear selector of a vehicle with an automatic transmission has not been shifted to the park position can allow the vehicle to roll away, increasing the risk of a crash.
A pinch bolt exists between the bike arm bracket and the upright assembly of the "Hitch" Style bicycle rack. When moving the bike arm bracket to its down position, this pinch bolt has the potential of causing severe laceration or amputation to the user's fingertips or hand.
