Re: 2011 grand cherokee 3.6 problem
cylinder misfire or engine coil issue. My 2011 had to have Cylinder 3 head replaces at 32k miles, and now at 64 engine coil just needed to be replaced as well. New engine in 2011 model has been nothing but a head ache for me. Waiting to pay it off so I can trade it in as soon as possible! cylinder head is under powertrain warranty- engine coil is not.
