Re: 2014 GCs that have steering shimmy over 60MPH

The incompetence of Chrysler and their dealerships is getting overwhelming. After failing to fix mine after 8 attempts it took 4 weeks to finally get someone from Chrysler to review my case again. After reviewing it I was told I needed to buy new tires out of pocket to fix my problem and if that didn't fix the vibration they would then look at my jeep again. That was probably the last straw for me. I let the customer care rep know if that's their official stance I would be proceeding with the lemon law as I already meet my states requirement of 30+ days in the shop. Is anyone else getting this kind of response from Chrysler?

Re: 2014 GCs that have steering shimmy over 60MPH

I haven't read every post so not sure if this has been mentioned...

If you have this issue you need to find a good tire shop (Most likely not the dealership) who can do a road force balance. Had this issue on all my cars w/ 20" wheels and this fixed it every time...

Re: 2014 GCs that have steering shimmy over 60MPH

Mine was at the dealer eight times. They tried tires , three sets same brand , I tried a set at my expense , didn't work . It is not the tires . they all cant be bad . The Goodyear Fortera is definitely a cheap tire . If some how this matter does get straightened out the Goodyear tires are coming off .
I just called Chrysler again to find out what is happening , had to leave a message .
On Tuesday I was told engineering is still trying to figure out what is going on . I am going to the dealer again this afternoon to get all the paperwork in order .
I guess we have to pursue the lemon law .
It is amazing Chrysler is still in business with all the issues they have .

I had a set of after market wheels on my VW that caused vibration. I did road force balancing multiple times at different places. It took 3-4 times before they got rid of it. Then I got a new set of tires and had to go through it all over again. Even with the road force machine, it seems like there is a technique or lack of training that can prevent a resolution to the vibration.

Re: 2014 GCs that have steering shimmy over 60MPH

How bad a vibration do you guys experience? I definitely have it in the 60-70MPH range, but I don't really feel it in the steering wheel, but if I take my hands off at about 65 MPH I can definitely see the steering wheel shaking. I'm hesitant to take it in just for that, as half the time I get tires mounted they scratch the edge of the rim.

Re: 2014 GCs that have steering shimmy over 60MPH

Update of sorts for my issue. My dealer's service guy called today. They opened a Star Case and were directed by factory to have me bring unit back in, and they will road force balance (again), then hook up vibration sensors and check it. I'll be going in next week.

In answer to the question in the previous post, mine shakes the steering wheel pretty good. Jumps rapidly 1/4 inch each way. The really odd thing is I drove it 20 miles on the highway yesterday and no vibration. Today, I drove it again and immediately upon reaching 60 mph, the vibration is there. I think it is something in suspension or the new power steering pump. We'll see.

I'll bet it has something to do with steering pump.

Keep in mind that most cars have SPEED sensitive steering. They back off the power assist as you speed up.

I bet it can't decide to be off or on, kind of like the headlights

I wonder how hard/safe it would be to disable power steering, just a for a quick test. You might need some assist all the time though.

When it vibrates "at 60" as some people say, does it stop vibrating when you go well above that speed?

If it were tires and many other things it would get worse as you go faster.

Yes, it stops vibrating above approx 70. From 62 to 68-70 it shakes. Below 60 or above 70 it is smooth. This is what makes me think it is the power steering pump as well.

The speeds you are mentioning don't really indicate the pump as the cause directly--and it's unlikely that would really be the cause by itself. It's likely a combination of suspension dynamics and resonance relating to the steering setup that makes this so frustratingly difficult to eradicate on affected vehicles.

The speeds you mention are pretty common speeds for imbalances in wheels and tires to be showing their worst symptoms for these overall diameters.

Guys it is definitely tires. I have these on my Durango and I have the same issues (2011) I have tried different tires and rims (same rim style).

I see these problems with Forteras like a bad joke. My new Jeep Grand will arrive at the dealership and immediately have the Goodyear's removed for credit and get some Michelin's put on.

What Willx said . You can balance Goodyears all you want and they'll show perfect...until you ride on them. It's hard to get a good ride out of a square tire

About 30 percent of the Forteras will Road force balance (rim match) and be good... the balance can be improved but the fact is if you have this shimmy there is a 90% chance it is the tires and you need to complain until they fix them...

I see about one bad on out of 10 so every 3rd jeep could have at least one. It is the one of the only things I will come right out and say I think it is a big mistake by Chrysler that they used these tires, they a prone to problems!
