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.
My left rear turn signal works and then it wont. Its intermittent. The message it causes is that the turn signal bulb is burned out. I took it to the dealer 09-28-2016 and they could not check it but indicated it sounded like a circuit board.
right front signal light not working and burning socket
The front right turn signal on the vehicle does not work at all. The issue was reported to the dealership on several occasions while under warranty. The dealership stated that the issue was the bulb socket, and the entire headlight assembly would have to be replaced at our cost.
Upon testing the system, it was determined by an independent mechanic that the problem has nothing to do with the socket. A simple switch of the (supposedly bad) socket to the passenger side showed it worked fine.
The problem was traced back to the TIPM which is causing both filaments in the bulb to illuminate at all times when the lights are on. There is no signal to the light for the turn signal only constant power, which is causing the socket and light housing to burn.
This problem is very dangerous. Not only can we not signal right, but the melting plastic indicates this could be a fire issue.
