These Forteras are not out of balance they are just cheap low quality tires that were put on there to save money.
I have the Michelin Lattitude Tour tires on my Limited that came with the Jeep. Although the dealer Road Force (RF) balanced them and said they were all within spec, still after moving the lower numbered RF balanced tires up front and adjusting the camber and toe-in, I still get a slight vibration in the steering wheel at 65MPH. Seems like anything below/above 65 MPH is fine. Just hit 1000 miles. I'm wondering if its an out of balance dive shaft, or just crappy Michelin Lattitide Tour tires.

The Jeep Dealer is still in the process of trying to determine the problem. We talked about the tire issue. Jeep dealer stated that they would have to get permission from Chrysler to exchange tires. The drive shaft is the next thing they are going to investigate, on Thursday. I will post the results. Later!

Re: Vibration in the 2014 grand cherokee summit

Had the same problem with my Jeep too. Tech was looking at something with a box and said that the BCM was programmed with 17" tires, but I have 20". He changed to match my tire and vibration was gone. At the same time another customer had the same problem and it had the same issue. Again fied issue by changing to match the actual vehicle. BCM is the body control module.

Have the dealer check that. Let us know if the same thing.

Re: Vibration in the 2014 grand cherokee summit

BCM (body control module) was set correctly, according to the dealer. Dealer installed a new drive shaft. Vibration/Shimmy still exist. Dealer stated that they are unable to improve Shimmy/Vibration in my Jeep Summit. Some GC Jeep Summit owners think the problem might be in the Tires. Trying to figure out my next move.....

Re: Vibration in the 2014 grand cherokee summit

Regarding the wheel vibration from 60-70 mph , the dealer installed new brake rotors , road forced balance three times , tried wheels and tires off of a new GC , vibration was actually worse . I also had a lot of vibration when applying brakes , that is why new rotors were put on . I myself tried another set of new rotors , indicated the flange of the hub with dial indicator , running within 0.001" , going to try measuring wheel run out on vehicle today and also check run out on CV shafts . My dealer claims he hasn't had any other customers with same issue . Are thes issues only on vehicles with 20" wheels and four wheel dive only ?
I am trying to gather as much information as possible

Re: Vibration in the 2014 grand cherokee summit

I have taken my GC Jeep Summit to two different dealers. After the changing of front tires, drive shaft, road-forced balances, wheels and tires change-out...the vibration/shimmy still exist. Both dealers stated that they have done all that they can do. My next move is: I will contact Chrysler Complaint Dept. directly. I will not give up!

Re: Vibration in the 2014 grand cherokee summit

My 2014 Overland has been to 3 different dealers for a total of 8 times and the problem still exists for me. My vibration is at speeds over 60. All 4 tires were replaced once and on the last trip another 2 tires were replaced. They also noted that the wheel size was set in the computer for 17" not 20" and they corrected that. Not sure why the other 2 dealers didn't check that on one of the other 7 trips.

Re: Vibration in the 2014 grand cherokee summit

The Jeep Dealer (mechanic) stated that the problem with vibration/shimmy in the steering maybe caused by the New Electronic Steering Control. Chrysler went from Hydraulic to Electronic Steering. If that is the problem, I am not sure what chrysler is going to do/or correct this issue. I think it may very well be the New Electronic Steering Control....all other attempts to fix the problem has not been successful.

Since 2011 the steering is electric. To the beat of my knowledge.

Re: Vibration in the 2014 grand cherokee summit

The steering is hydraulic. It's just the pump that is electrically powered.
