Poltergeist possession

Hello to you all this is my first post for my 2010 grand cherokee and it’s a doozy!

On occasion my the battery goes dead on my Cherokee. The alternator, voltage regulator and battery all check out good. Checked for excessive overnight parasitic draw from the battery and nothing abnormal.

Finally I found something abnormal. After parking the car and locking it as I turned to walk away something strange happened. The passenger and drivers windows rolled down, the headlights and rear running lights came on. The hazard flashers turned on. The rear hatch glass opened itself and the rear hatch lock unlocked and continued repeatedly unlock itself. The car kept doing this until the battery was completely drained. I could not stop it!

has anybody else had this experience with their grand Cherokee?

thank you all in advance for your reply,

Right off hand, I would think that all these items relate to your remote control unit. If this is correct, that might be the problem. For your battery, I would start looking at the terminal connections for any looseness or corrosion. You have to start somewhere.

 

Welcome @MudBunny ....you’re issues would make more sense if you had mud run this JGC. After confirming solid positive and ground connections do some research on TIPM failures that have occurred with various Chrysler products. BIL ‘94 JGC had similar issues that required a new ECU.
