2019 MKZ 3.0 AWD Car vibration, why??

[Jacklisk]

Just got a 2019 3.0 AWD MKZ a few days ago. Steering wheel vibrates from what feels like road/something mechanical, feel the vibration through the seat as well, and just the entire car while driving on smooth highways. Brought it in, they balanced wheels. Problem still exists. Thought it may be permanent tire flat spotting as it is last years left over model I got, but now after reading about a driveshaft issue I’m thinking this could be it instead. Is the problem still prevalent with ‘19s?? How ridiculous if so. I shouldn’t have to deal with such annoying vibration in a $55k car or any new car for that matter. How is service supposed to know how to fix this problem? I know beforehand they’ll play dumb like they don’t feel the vibration. Tried it the first time. I’m not optimistic after reading this CnD review 2017 Lincoln MKZ 3.0T AWD though it references a car with different size amd season tires then manufacturer recommended on the door jam. Any advice os appreciated, thanks.
So far very disappointed with Ford/Lincoln.

2019 MKZ Steering Wheel vibration at speed before and after balancing

Hi All, I just got a 2019 3.0 AWD MKZ yesterday. I noticed the steering wheel has a vibration at speed on the highway; i can also feel this vibration in the rest of the car and my body. Its not heavy, but noticeable. I went in to service.They did a balancing. Problem did not go away. It doesnt...

AWD Models of MKZ - Beware of Driveshaft

Owners and potential owners of MKZ AWD models: The main driveshaft connecting the front to rear, is a Ford Only part, and very expensive (part only ~$750.00). These units are notorious for failure. I have seen online that this issue is common on the AWD units after about 35,000 miles of use...

Hi Jacklisk. Several things: First, you already have two threads asking the same questions, as jkeaton mentioned. It is best to have one thread with all information, replies and answers in one place. Makes it easier for people to help you.
Next, it is a new car with a full warranty. Tell your Service Department the wheel balancing did not solve the problem and let them properly diagnose the issue.
Last, no the driveshaft issue is not a "prevalent" or common issue. Like any problem, it can happen, but is not a common issue. It is not likely, but still possible that could be the cause of your issue. But the only way to find out is by taking your car back in for service. You are wasting time asking online about this type of issue, when you still have a warranty.

There is no way the vibration issue in your car can be diagnosed over the Internet. There are far too many possibilities and variables. For a problem like yours, it is best to take your car back in for service and stop asking online. Use your Warranty and use the complementary loaner or Pickup and Delivery service.

Keep us updated and good luck.

Thanks bbf,
I would have more faith in the service dept if after they balanced the tires and test drove it they were truthful about the vibration not going away, and would have looked elsewhere. I’m scheduled to bring it back in. If it can’t be fixed I think I should be able to return the car. That’ll be another hassle.

Hello. My wife has a 2017 Lincoln MKZ 3.0 AWD. Purchase the car was 26,000 miles and it had the vibration as well. After replacing rims and tires and taking it to three dealerships insisting that they checked the driveshaft. I finally got one dealership to follow through. They said that they removed the drive shaft and took the car out on the road and the vibration was gone, therefore it was the driveshaft all along as I kept insisting. Ordered a new drive shaft and the vibration went away. Apparently it is very very common on all wheel drive Fords and Lincolns for the drive shaft to become unbalanced.

When it does that do you see a picture of a coffee cup on your gauges?? If you do it is telling you to stay in your lane because the car is getting to close to the lines.

If you go into the menus using the steering wheel controls you can reduce the intensity or shut off that feature.

And if the driveshaft was removed how was the vehicle able to move" It would transfer the power to the output shaft where the driveshaft was removed from and that would spin but the vehicle would not move at all.

MKZ is Front wheel drive or all-wheel drive.
The driveshaft is only for all-wheel drive. To transmit power to the rear.
Operating in front wheel drive only does not require a drive shaft.

I am fairly sure the vehicle is not gong to move if the driveshaft is disconnected and this is why.


The PDU or transfer case is a separate component that attaches at the output shaft opening for the passenger side front tire. The passenger side front axle then goes into the PDU. off the back of the PDU is where the driveshaft gets attached for the rear wheels.


AWD means just that. all wheels have the capacity of accepting power at all times. On a FWD vehicle if you lift one of the drive tires off the ground and start the vehicle and put it into gear does the car move? no it doesn't. the wheel that is off the ground is going to spin. The AWD functions in the same manner. This allows the wheels to be able to spin at different speeds and this needs to be done to keep the tires from binding on the ground when having the vehicle turn. In a corner each of the 4 wheels are going to make a different number of rotations to go around that corner. By disconnecting the driveshaft you would end up the same issue as lifting one of the drive wheels on a FWD vehicle the car would not move and you would see the yoke for where the driveshaft attaches just spinning.

On an old 4WD vehicle you could do what you are talking about and that is because only the rear axle allowed the rear tires to spin at different speeds and that function was done internally inside the rear differential and not by the transmission or the transfer case. The front wheels would turn at the same speed to each other and that is why you should not use a 4WD vehicle with 4WD turned on unless the vehicle is on slippery/unstable ground. If 4WD is enabled and you attempt to say back out of a parking spot it is going to feel like the vehicle is going to rip the front tires off. The transfer case and the transmission has no ability to allow the rotational speeds of the wheels to be different. The components between the engine and the driveshafts are only contain gear changes and shaft output direction changes nothing more so when disconnecting a single driveshaft the other one keeps on spinning at the same rate that it would if both shafts were connected.


The same transmission is used on both the FWD as well as the AWD cars an seeing as how there is only axle outputs from the transmission the ability of the wheels to rotate at different speeds has to be a function of the transmission internally. In order to add the additional 2 wheels into the mix one of the axle output shafts would have to be used while maintaining the original function of allowing both front wheels to spin at different speeds. The only way this is able to be done is to have the driveshaft work exactly in the same manner as the wheel would in the front if it was a FWD only vehicle. while the differential on an AWD is what allows rotational speed differences between the wheels attached to the back the transmission of the vehicle does as it is designed and allows rotational differences between the wheels on the front. because the PDU is attached to an axle output shaft it now has to act just like a single axle would if it didn't then you would lose the ability of the front wheels being able to spin at different rotational speed than the rear and binding issues when turning would occur between the front and rear wheels when turning on dry and stable surfaces.
