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.
Took my Jeep in to have it diagnosed. Being told that my Jeep is not getting fuel and that the fuel pump relay switch is needing to be replaced along with a wiring kit and a few fuses. My Jeep was having issues such as the rear door locks going out, stalling in the middle of the road, car alarm going off unprovoked, and issues cranking. Now I don't think all of these issues are related to the fuel pump although per my investigation the TIPM can turn off the fuel pump power.

I couldn't start my car. The starter would go but it would never turn on.
