The MDX has been one of our higher-rated models. We like its strong, refined powertrain and pleasant ride. The comfortable interior offers good visibility, seating for seven passengers and a very decent amount of cargo room. The MDX also feels agile in routine driving, but does not inspire confidence in emergency handling, even with its stability-control system.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit.
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.
Fuel Economy & Emissions
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Greenhouse Gas Greenhouse Gas The Greenhouse Gas Rating represents the amount of carbon dioxide the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).
NA
Smog Rating Smog Rating The Smog Rating represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

"The bluetooth unit in the car malfunctioned and was constantly drawing voltage from the battery causing the battery to run down constantly. I think the problem started very shortly after I got the car because I have had to replace the battery in less than two years time ever since I got the car. I have had to jump start the car close to 100 times since I got it. The dealer could never tell me what was wrong with the electrical system after multiple times in the shop. I found information on the internet that led me to the problem. It appears a class action suit was brought against Acura because of this malfunction but it never got anywhere. I watched a video explaining how to disconnect the bluetooth unit and since I disconnected it, I have had no more problems with the battery running down. I wish Acura would admit this is a problem and recall their cars with this unit installed. I spent a lot more on batteries for this car than I should have. The listed cost to 'repair' this problem is over $1000. It should be replaced for free."

Anonymous, TN (2006 Acura MDX None 3.5-L V6)

"The hands free system stopped working a couple of years ago. Soon after, my car battery kept dying. I read up on things and found out that in this model, even if the hands free doesn't work, it still drains the battery. I looked on YouTube to find how to disconnect it as that would stop the battery drain. The cost to replace is too high on this old of a car so I disabled it and that stopped the battery drain. It's easy to disable it and saves money from having a mechanic do it. It took me less than five minutes."

""Stuttering" while driving. Car would vibrate at certain speeds"

Anonymous, WI (2006 Acura MDX None 3.5-L V6)

"The Transmission suddenly stopped working while I was on the highway with my daughter in the car. We required a tow to the repair shop. The replacement took several days, cost around $4,000, came with only a 1-year warranty, and used refurbished parts, which was not what I asked for. The problem recurred several weeks later, and that repair (under warranty) took three more days. I will buy a different car before I repair this transmission again."
