What Our Members Are Saying about the Reliability and Durability of the Acura MDX

Acura MDX Reliability and Durability: Pros
YearBody/PowertrainComment
2012 4dr SUV 300-horsepower 3.7L V6
6-speed shiftable automatic AWD
We've owned several Acura's over the past 13 years, this is the first SUV. The past has proven their reliability as long as you maintain them. I mean the basic prescribed routine care every 5,000 miles. I've driven many different American made vehicles supplied by my Company over the span of the last 35 years and none can compare with how Acura's hold up or perform, even with the same routine care and still offer the resale value that they do.

I am not worried about breaking down or about expensive repairs. This is a vehicle I can keep with no worries.

i have owned several acura passenger vehicles and the reliability is unbeatable in my opinion. as it turned out i did have some front end thunks in my MDX. at no time did the dealer ever admit defeat (they all do that) and always made me feel welcome.

This SUV is a dog! Engine mounts, transmission, AC, alternator, cooling fan have all failed catastrophically. I will not buy an Acura again

It appears from others to be a safe and reliable car. If the engine holds up as well as my other I should have it a long time. It has 60,000 mile but looks and drives like new.

Got in mechanical trouble all the time~~~
2001 4dr SUV 282-horsepower 4.4L V8

The worst car I have ever owned. The transmission failed 4 days after the warranty was over - and the vehicle had less than 45,000 miles on it then.
