Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My mechanic determined my front and side motor mounts need replacing, and mentioned it being common in my vehicle. I've since found others with Acura mdxs with the same problem. Never needed mounts replaced in any other vehicles owned. I believe it to be an inherent defect Acura must address.”
NHTSA complaint #10370269, filed 2010-12, 79,000 miles“Over a period of time, beginning about the date and vehicle mileage stated above, I experienced a shudder and corresponding noise as the transmission tried to shift gears. Similar to the sensation of driving across closely-spaced rumble strips, the shudder and noise seemed to vary in length of time depending on speed. This occurred many times before I became concerned and started researching during which I found dozens of similar accounts in various on-line forums. Eventually I took my MDX to the dealership for a diagnosis. …”
NHTSA complaint #10660836, filed 2014-11, 102,912 miles“I was moving out of a parking space and bam!...the drop of tranny fluid and radiator fluid on the spot. When I took it to a mechanic, they told me this was the 4th honda car they have had with same problem, they found out in all cases it was the pressurized hose connecting these two important parts had corroded to the point of failure. I have been hearing more about this and it is now disturbing to me. In my case my tranny is fine and all I needed was a new radiator and all new fluids. The car was not able to move and that may have saved the tranny. …”
NHTSA complaint #10535319, filed 2013-08, 149,052 miles“I bought a new Acura MDX 2004 and in two days the engine malfunctioned, light appeared. I went to the dealer, who said that I need to make an appointment to fix the problem, eventhough as a new customer I was not satisfied with the car, indicating a problem within two days of driving less than 100 miles. I did some research on the problem and found that the issue I am facing is a known issue within the range of my VIN number. But Acura dealer and the customer relationship office in la denied that they know about the problem. I also found a similar the issue documented on your website. …”
NHTSA complaint #10075033, filed 2004-06, 50 miles“Sudden transmission failure on the highway. Lose all power from the engine to the wheels. Has to pull over suddenly in traffic to avoid being hit by other cars traveling at normal speed. The transmissions on honda/Acura v6s apparently have systematic problems.”
