I bought my 1st new 2014 ram 1500 Laramie feruary 1st after owning fords all my life. I am 55 yrs. old. well after driving it for 2 weeks and 600 miles I am getting a vibration at 2000 rpms. higher or lower rpm there is no vibration. I have the 3.92 so the motor is spending a lot of time in that rpm range and it gets annoying. so I called dealer today(feb. 14) and service advisor says he had a ram in there last week with the same issue. he said they determined it is the CHARACTERISTIC of the truck. I feel it in the steering wheel and thru the gas pedal. it is definitely in the drivetrain. does every ram have this vibration?

Does it always vibrate at 2k rpm not matter the load on the motor/drivetrain? I get an occasional vibration at 30 to 40 MPH but only when the ECO light is on and I give it light throttle. As soon as I apply a little more throttle the ECO light goes out and the vibration stops. I imagine it is the engine running on four cylinders that is causing the vibration is my truck. If yours only does it at about 2k rpm it could be a torque converter or a bunch of other things. How bad is the vibration? Is it something you feel or does it show in the mirrors or somewhere else?

from a stop, I don't really feel the shudder thru 1st 2 shifts. then as rpm goes to 2200 rpm and shifts to next gear, rpm drops to 1900 to 2000 and I feel a vibration. also if I am cruising in 5th at around 40mph and rpms are at 2000 the truck is not smooth. there is a vibration throught out the truck. the vibration is not really bad where it shares the mirrors but is annoying enough. especially on a $51,000 truck.

From what I have experienced and have learned from other forum posts, it happens at about 1800 - 2000 RPM, in all modes (regular and in tow/haul modes), 6 & 8 speed transmissions, 2wd and 4wd modes, etc. EXCEPT when in park or neutral. In park/neutral the torque converter clutch is not engaged.

Same issue here!

Hi All,

I have the exact same issue here. Happens throughout all of the gears right around 1800-2000 RPM. The steering wheel and gas pedal vibrate very noticeability. I haven't contacted the dealer yet as I wanted to see if anyone else has seen this issue. I hate going to the dealer without documentation and proving this is happening to others.

Has anyone got their issue resolved?

Any info would be great appreciated.

I have a 2013 Dodge Ram Sport 1500 Hemi 4x4 with 8 speed transmission.

Thanks,
Lloyd

I would guess that your transmission is in to high of a gear . It is lugging. try to manually shift it down one gear and slow to same rpm and see how it feels. With the need to maximize fuel economy the trans is programed to be in high gear as soon as possible...... just my 2 cents! With enough complaints chrysler may have an update to the computer but would have to sacrifice fuel economy abit!!

Please read prior posts

It has nothing to do with what gear you have it in. If you are near 2000 RPMs you will feel a vibration in the steering wheel and gas pedal. My issue is getting worse. I just got back from the dealer yesterday and all he did was a PCM update. After the update I took him for a ride to confirm the issue. He said he'll contact Chrysler and get back to me. Hopefully with some positive news. I paid $40K+ for my rig and I don't plan on living with this. It's extremely annoying and just started to happen after 5000 miles. I'll let everyone know what I find out from the dealer in the next day or two.

Hey guys I had this issue a long time ago with one of my earlier vehicles (ford) it was a bad torque converter but instead of wasting a lot of money on replacing the converter I just replaced the transmission fluid with synthetic (has to be synthetic and this was from the transmission mechanic) I have also done this on my truck even though I didn't have a vibration I didn't want to take the chance I have over 9000 kms on my truck and still no vibration. Just an idea.

thanks, I think I am going to do that with synthetic!

Hi All,

Sorry for the late reply but I think I have a pretty good idea what is happening with the 2000RPM vibration issue. I want to be clear that this is NOT related to speed of the vehicle. It's purely RPMs and how much load is on the engine. The people with this issue know what I am talking about. When your truck reaches 1800-2000 RPM you can feel a vibration in the steering wheel and gas pedal regardless of what gear or towing mode.

So I brought my truck to the dealership regarding my issue and the service techs honestly didn't even look into the issue. I got the run around. I complained to the service manager and he said there is a Chrysler field engineer that will be in the area within a day or two and if I can bring it then. I said absolutely. I met with the field engineer and he drove my truck and he said its exhaust drone. I asked why didn't I feel this when I bought the truck? He didn't have an answer. My issue was getting worse as time went by. He said drive my truck which was the same year. I could feel the same vibration but it was much much lighter and barely noticeable compared to my truck. The field engineer said this is the characteristic of the truck. There was nothing more that he could do and I felt a little blown off. Nothing was resolved.

I did a LOT of research about exhaust drone when I got home. Surprisingly most people experience exhaust drone around 2000rpms with V8's. When I think of exhaust drone I think and audible sound resonating in the cab. Well that can be transmitted differently depending on the style/build of the vehicle. So maybe I was onto something here.

As we approached spring/summer time I noticed the vibration getting lighter and lighter. Of course there is the ah-ha moment. I purchased my truck at the end of May 2013. At that time the weather was extremely warm. I didn't notice a thing until about November/December of 2013. As the weather got colder and colder it got worse. At that time I didn't think about temperature as a factor as the issue was just getting worse. I brought my truck to the dealer near the end of March when the temperature was warmer but still cold. The vibration wasn't at its worst and maybe the field engineer didn't think it was a huge concern because it wasn't really that bad that day. Now that summer is here my vibration is virtually gone. Now that I'm more "in tune" with my truck I can CLEARLY feel the vibration get worse even with slight temperature changes. With temperatures 70 degrees and up it's virtually gone but ever so slightly noticeable but nothing to complain about. Around 50-60 degree it is noticeable to me now but nothing that I would complain about IF I didn't notice it before. 20-40 it's definitely noticeable. 20 degrees and below it's extremely noticeable. And with this extremely cold winter it was very annoying. Annoying to the point that I don't want the vehicle if it continues like this.

My best guess to what the issue is are the rubber exhaust isolators, frame dampers, or the harmonic balancer. All of these items and their dampening properties would change based on the outside temperature. And I can easily see how a bad batch of these items could easily pass inspection at normal room temperature.

I haven't talked to the dealer about my findings yet but after writing this email I am now motivated again to talk to the dealer. I don't know about the rest of the people out there but talking to the dealers is like talking to a wall. I don't quite understand their lack of wiliness to help people when they spend $40,000+ on a vehicle with a very annoying problem.

I'll let you know how round three goes with the dealer. If anyone else has something to add please do! This will help me and others solve our issues!

Thanks,
Lloyd

Hi All,

After re-reading some of the other posts I'm thinking about tossing the idea from the Chrysler Engineer as exhaust drone. I'm going with 2 ideas... Harmonic balancer or transmission vibration. My reasoning is that the vibration is prominent on the steering wheel and gas pedal. Someone said they changed out the harmonic balancer which resolved their issue. Since the harmonic balancer is made of rubber and metal, temperature can easily affect the characteristics and not eliminate certain vibrations that are naturally caused by the engine. OR the vibration is coming from the torque converter and the rubber isolators and dampers are less effective during cold weather.

If the person who changed out there harmonic balancer reads this please reply or send me a private message.

If anyone has more information about the torque convertor please reply or send me a private message.

Took my 2013 ram 2500 back to the dealer again for the vibration problem and a water leak under the hood, They aired down my tires and said it's the vibration is normal for this type of truck, Then why did they replace the driveshaft the first time?? Also the water leak was normal also??
Seems there's a few trucks with this problem and maybe Dodge isn't concerned about it.
Hopefully there will be a fix for this.

I hate to stir up an issue that has been down for almost a year but my 2015 has 37000 miles on it and it just started about 1000 miles ago. I can feel it in the console the most if i put my hand there. Also temperature does not matter. I had my wheels and tires rotated and balanced. I also changed out my brakes and rotors. Still vibrating.

Anyone have a fix for this yet?

I think your issue is a little different from ours. Ours happens at roughly 1800-2000 RPM during cold weather and gets worse the colder it gets. I have come to terms with my issue as I believe it's a characteristic of the truck (sympathetic vibration from the motor or transmission as the frame stiffens when it's cold). Dodge obviously tries to take care of this issue with the large frame dampers under the body of the truck.

I had my transmission replaced once already due to a whining noise going in reverse. The vibration is still there. I'm getting the transmission replaced again due to a valve body noise when the transmission is cold.

I'm curious... Under what circumstances does your issue happen? RPM, speed, gear, outside temp, motor and transmission temp, etc...

Hi 14bluelaramie,

We are experiencing the sames issues. My happen roughly around 1800-2100 RPMs. You don't noticed the vibration during the warm weather but is noticeable starting at 45 degrees or so and gets worse as the outside temperature goes down. I think as the outside temperature gets colder the frame gets stiffer and the frame dampers become less effective. I believe the vibration is coming from the engine and the harmonic balancer isn't as effective during the colder outside temperature. I would really like to try an aftermarket fluid harmonic balancer. I'll try to make a point to call a few places and get their input to see if it'll be a worth my time and money to upgrade.

did you ever look into the aftermarket fluid harmonic balancer?
 
#28 ·
Yes. I called 2 places. The first didn't make one for our Hemi engine and didn't have plans to make one. The second place I called said they didn't have one for our Hemi engine either but it's in the works to be designed. http://www.fluidampr.com They have my name and number. So when it's time to test I'll be on their list. The fella that I spoke with said that their product should be able to correct the harmonic issue.
