Bought this vehicle after extensive research. After narrowing down to X5, MDX and Highlander Hybrid, MDX was the clear winner. Owned CL and TL-Type S and liked the included standard features as compared to other luxury vehicles. Main complaint is the required premium gas and gas mileage. I also have had the thump, thump after starting and accelerating to 20 MPH. Took to the dealer and they identified it as a "bushing issue" which there was a service bulletin for. They made the repair, but still have the thump. Will have that checked out again at next oil change. Overall, very comfortable and great handling.
Included standard features as compared to other luxury SUVs. Excellent handling and comfort. Great sound system. Really like the 300hp engine and smooth acceleration. Nice amount of cargo space. Fun to drive!
Increase fuel efficiency. Voice recognition can be difficult to master; would be nice if it could respond to a bigger variety of commands. Add siding and rails to standard equipment. Some of interior materials on the gauges appear cheap.
