2011 INFINITI M56 4dr Sedan (5.6L 8cyl 7A)


Review

I'm happy with just about everything on and in the car except the transmission is jerky and undecided as to what gear it should be in at slow speeds. Between 20 - 40 mph, the gears shift up and down over 1K rpm because the computer can't figure out what gear to be in. The car actually jerks back and forth. Infiniti knows about this and is working on it.


Best Features

nice sound system, maybe a few more features needed in the storing and playing of CD's


Worst Features

Keyless entry, you need to physically push the door handle button, the 'Blind Spot System' has blind spot and lane changing on the same button that can't be reached while you're diving - they should be in the Set Up on the screen.

2011 INFINITI M56 4dr Sedan (5.6L 8cyl 7A)


Review

Have owned many luxury and sports luxury cars. This one is my first Infiniti and the most fun to drive. Excellent power although acceleration is not a smooth as competitors. Excellent ownership experience so far despite some hick-ups.


Best Features

Powerful acceleration. 420 horses. Beautiful interior. Great radio with speakers everywhere.


Worst Features

Lane departure system is annoying. Need to turn it off each time I start her up. Excessive dirt on rear bumper (white car) above dual exhaust pipes that has already required 2 trips to dealer to clean with a special solvent that is clearly an exhaust design flaw and is in need of a fix

2011 INFINITI M56 4dr Sedan (5.6L 8cyl 7A)


Review

Infiniti has gone to great lengths refining many aspects of the M for 2011 but there are still many things that need improvement. While I enjoy my M56 a lot, there are features that worked better on my '08 M45 (such as XM NavTraffic, which is a disaster on the M56 and every other 2010+ Infiniti model). And there are features that are completely backwards, like the armrest button you press OUT to fold the side mirrors IN, and the song selection button you press UP to switch to the next song DOWN on the list. Doors lock automatically at 15mph and you can't do anything about it. And there is so little ability to customize the warning/intervention systems that one is inclined to leave them off!


Best Features

Blind-Spot Warning/Intervention; no more legal challenge from the navigation system every time you turn on your car; gorgeous interior; more-powerful engine with better gas mileage than M45; Forest Air; ventilated front seats; comfy front seats with Deluxe Touring Package; Malbec Black exterior.


Worst Features

The Around-View Monitor found on the FX, EX, and QX is the most egregious omission from the M. (The BMW 550i has it!) There isn't any form of visual/audible distance warning for the front end and four corners, which is ridiculous. Also, add a Valet Mode, and enable Bluetooth Call Waiting/Caller ID.

2011 INFINITI M56 x 4dr Sedan AWD (5.6L 8cyl 7A)


Review

This is my 3rd M and is the the best of the lot in all aspects except one. The transmission is a disaster. It has too many gears and is constantly searching for the correct one. Very annoying. It's a magnificent beast on the highway on a long trip. Not meant to be driven around town.


Best Features

"Blind Spot feature is fantastic. Very comfortable seating and plush interior. Sound system is unbeatable.


Worst Features

Motor locking trunk should be standard at that price. One of the 4 drive modes should be for city driving.
