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.
TIPM stalls electrical system malfunctions in dash unit
TIPM module is defective and dealership does not have a replacement or recall at the time in July. In extreme heat inside the cabin around 94 and up when you turn the vehicle on the dashboard goes wild and will not work. This was not help by dealership saying there is nothing they can do. It took about 35 minutes before system starting going back to normal, because engine and power steering are the only things that work. So you drive with door open or sweat for 35 mins driving until unit cools and starts working.
