I had my 2012 Charger R/T Max for 17 months and sold it.
The 4-6-8 cylinder system fights with the transmission in traffic.
It's constantly trying to drop back to 4 cyl mode which cuts your low end torque in half, makes it downshift, then the other cylinders kick in while the engine races.
It's totally confused!
Build quality is great except, drivers seat power actuator moved jerkily and had to be replaced.
Had radio replaced once and then rear channel failed again.
Started smelling antifreeze inside the car at 25,000 miles, needs new heater core.
Clunk in rear end when shifting gears in stop and go traffic.
Over engineered and under built!!!
All the bells and whistles of a $60K mercedes for $34K.
Most of which worked.
Love the power when it's not in 4cyl mode.
(unfortunately it's always in 4cyl mode if I'm not stomping on it)
Switch to turn off Multiple Displacement Mode or better yet, just eliminate it.
I got the same gas mileage manually shifting it into 5th gear on the highway which is supposed to turn off the MDS.
It's total kitch to make people think it get's better gas mileage and sell it to V6 shoppers.
Needs a tighter rear end, major clunk issue in stop and go traffic.
Put in a 6 speed transmission. Better quality head end for sound system, mine failed twice.
Better seat actuator, runs rough.
