CarComplaints.com Notes: The fourth generation Grand Cherokee took the relatively trouble-free run of the 3rd-generation and flipped the script.
From 2010 to 2011, complaints about the vehicle not starting increased 10-fold. In fact, the 2011 model year is riddled with engine problems and a defective TIPM might be to blame. The TIPM (Totally Integrated Power Module) distributes power to all the eletrical components in the vehicle, so when it starts acting funny so do numerous other components in the car. Orders for new TIPMs were so abundant that parts became scarce, prompting a class-action lawsuit claiming Chrysler ignored this obvious defect.
By 2012 complaints dropped back down by about 80%. Needless to say, if you see a used 2011 Jeep Grand Cherokee on a lot just keep walking.

not sure (2 reports)
hall effect magnet ring within window motor misaligned (1 reports)
Right front (Driver, RHD market) power window won't roll up/down continuously, rather stopping every 2 inches.
OBD scan revealed "B185A-31 DRIVER WINDOW POSITION SENSOR - NO SIGNAL", fault traced to power window motor, within which is a hall effect sensor ring, which was misaligned along motor shaft. The hall effect sensor reports position/speed to DDM (driver door module), since there is no signal, the DDM continually cuts out window motor when switch is pressed.
Power window motor does not need to be replaced, despite manufacturer saying it is a non-repairable part.
Solution: move hall effect sensor magnet ring to 7.5mm from motor commutator face in order to realign sensor correctly. Problem should be fixed.
The door on the driver side window stop working last year but the lock stopped working in 2013. I do not know why the window mechanism would not work unless there a defect in the design or the vehicle prior to my purchase in 2012.
The driver side window stopped going up or down smoothly. Normally the window will go all the way down or all the way up if the button is pressed firmly. Or it will go all the way down or all the way up if you hold the button down or up.
However, since the problem started happening, the window will only go about 4 inches at a time and then stop. To roll the window down or up fully I have to hit the button about six or seven times in succession.
I have not brought the car back to the dealer to look at the issue since I don't trust the the dealer after I went for an oil change and they tried to sell me a new tire that I didn't need. I hope to resolve it on my own when I get a change to look at it more closely.
