It's always done that from day one. More than likely motor mounts.

 

My motor mounts were replaced, it came back within a week. They also replaced the torque converter.

 

If it went away initially after the mounts were replaced, I wonder if filling the voids in the mounts with window weld would help.

 

have an 07 with almost 200k miles on it
has had its share of problems
but never had any engine shake/vibrations

 

Mine vibrates one day and wont the next...

 

Mine is worse if the air conditioner is running.

 

I only feel it when my ac is on, other than that I've never really felt much

 

My 2007 has no vibrations and when I start it fires right up. It starts as soon as I turn the key, no cranking at all. I guess I should knock on wood.

 

This doesn't have anything to do with starting it?

 

I did an experiment yesterday, I was stopped at a red light, air conditioner running, felt the shake when just idling. I pressed the brake to the floor and gave it a very little bit of gas. With the engine sitting at about 1,000 RPMs, everything was perfectly smooth, no vibrations at all.

So, this to me would say that the vibrations some are experiencing is due to the low idle of our Patriot engines.

 

I have 2007. No vibrations.

 

That's exactly my thought too, I asked the dealer if they could just raise my idle a little. (even 50 or 100 rpm) and see if it smooths at all, they claim they can't with their software. Wish we could tune these, I could do that in 5 minutes with my Saabaru.

 

Yeah, it was smooth all the way down to the 800-900 RPM range.

 

Welp, dealer called Chrysler is now saying it's "normal" and not willing to do anything with it... Awesome. Admittedly it's not as bad when it's cold out, we'll see what it does when it warms up.

 

Mine does this as well. I have found that if it I put it into Nuetral and then back into Drive, the vibration lessens significantly. Mine only seems to do it after running at constant RPM for an extended period. Example.... Driving on the highway at a constant speed, take an exit ramp and get to a stop light. At the light is will shake. If I click the shifter into Nuetral and then back into Drive it pretty much goes away. Mine has been this way pretty much since new, and when I mentioned it to the dealer during a CVT service appointment, I was told that several people have brought it up, but Chrysler says it's normal operation, and they won't mess with just for that.

 

I have a 2014 patriot with 8150 k and it vibrates every time I come to a stop I was told by a motor rebuilder that its your harmonic bellancer there is nothing we can do to get them it fix it because they are not willing to do what it take to fix

 

It's a big, rough 4 cyl. Some do it more than others. I've had new Patriot rentals that shake worse than mine.

For me the shake went away after having all 4 engine mounts replaced. The mounts absolutely need to be installed properly, they are left loose while the engine is allowed to idle in Park or Neutral, then torqued to spec. This puts them in the best position and alignment. My rear engine mount has been replaced twice to favourable results.

 

My new 2016 vibrates pretty hard at a stop light with the A/C running. No A/C, barely any vibration (no more than the average car). It's definitely an issue with engine load. It's the only thing my wife complains about our new Patriot.

 

My 16 has less than 500 miles on it and I am constantly checking the tach to make sure it's idling high enough, sometimes feels like it's going to stall while sitting at the light.

 

11' with 90,000 miles and it has a small vib to it and like everyone else says it's worse under load from the AC. I do have a strange noise when accelerating from 1800-2000rpm

 

It's the torque converter. Put it in neutral and it will smoot out. A/C raises RPM and puts more pressure on the on it making it even more noticable. Really shouldn't sit in gear for long peroids of time stopped anyway.

Maybe this poll should specify the engine size. My 2.0 is easily one of the smoothest inline fours I have owned. Many times I've caught myself cruising along at 4000 rpm in second gear when I should have been a gear or two higher. Is it a function of engine size and/or transmission type? All I know is the 2.0 and 5 speed is super smooth.

 

5speed, I think the OP has an automatic/CVT. With a 5-spd either you're in neutral or have disengaged the clutch, so there is no load on the engine and hence, no vibration.

I think what everyone is describing is the normal load put on an engine when stopped at a light. Any automatic will probably have a vibration under these conditions. Since the transmission is still engaged it is putting a modest load on the engine -- add to it the a/c compressor and possibly the alternator because the fan is drawing power, and yes, its quite a load on an engine that is running at necessarily low RPMs. Running that slow it doesn't muster much power and the engine will be straining. I too have some vibration under those conditions; I know my spark plugs are old and I notice some misfiring as well. With new plugs I'll still get it.

 

I have an automatic.

I've owned 20+ cars in my lifetime, (granted about half manuals.) Our 2002 impala with 250k idles smoother with a vacuum leak than this Patriot does when sitting at a light. In fact I've owned a lot of beaters over the years, and they all idled smoother than this thing does. My belief is it idles so rough because of a couple things, a very low idle RPM, (to help with emissions.) and the torque converter being very tight, (also to help with emissions.)

 

Yes, I was trying to separate the culprit as to engine or engine/transmission.

 

Our 2012 2.4L CVT Patriot is going back to the dealer today for this very issue. The vibration is sometimes so bad that the horn cover shakes likes a rattle can on the steering wheel. I'll let you guys know if they come up with any fix...

Keep us updated and let me know if you're in need of further assistance. Thanks - Kevin T, Social Connect Team

 

Torque Converter, patriots have a low stall speed as someone mentioned earlier and it tries to engage at just above idle. The A/C will bring the RPM to just above idle and the torque converter tries to engage, but is fighting your foot on the brake. Not that difficult of a concept. If you put it in nuetral and it quits vibrating, must be the torque converter.

^^ This ^^

 

I got a call this afternoon from the dealership - they are replacing the crankshaft pulley (covered under my extended warranty) and are going to see if that resolves the vibration...

 

Well, at least your dealership is trying to solve your problem. Some places would ignore you and hope you'll go elsewhere.

 

Mine will get a bit rough when stopping on a severe hill either up or down.
