Hi,New to the forum!! Picked up my baby two weeks ago has vibration from 30-70 plus.I was told by the sales manager give it about 2-3hundred miles to get the flat spots out.Well today I brought it in for a diagnosis with 500 mi I was told two wheels slightly out of balance and everything else was OK.Left the dealership with my same problem very aggravated!!! The balance was done with road force machine,also have Pirelli tires ( zero nero).I live in North Jersey,any ideas would be greatly appreciated.
Thanks in advance jim

 

Had a almost identical problem. Took them in for balancing and it was worse. Even after road force balancing the wheel was still shaking. They replaced the front tires and shaking was gone. Then the road force balanced the rears and told me they were within spec. It appears that it has been a satisfactory solution. Review this thread: https://www.jaguarforums.com/forum/x...balance-47001/

 

After two weeks how was your issue resolved?

 

Problem resolved,all four pirelli tires were replaced. I still feel a slight sensation in the wheel but was told that was from the road.I maybe expected to much from this Jag. My BMW 535I did not have any road feeling what so ever. Thanks

 

That was my impression also that the tires had a defect. I may start a thread regarding defectives in the factory OEM tires. Sometimes it's hard to tell if the road surface is being felt through the suspension or it's the tires.

 

I've had the very same problem on my 2012 XJL from the very first day. Changed tires, balanced them several times, still the same vibration. Now I am running our 2012 XF wheels and tires on the XJL which makes it better but, underneath of the softer sidewalls the vibration can still be felt.

I am very disappointed with this car. Jaguar said in the 2013 release doc:

http://newsroom.jaguarlandrover.com/...technology.pdf

"All models in the range benefit from recalibrated spring and damper tunes
offering enhanced ride isolation and occupant comfort on all road surfaces, with no impact on the model’s acclaimed dynamic ability"

Looks like they were attempting to address a problem very similar to what you and I are describing. Seemingly they have not been able to get rid of that chassis vibration, assuming yours is the same as mine. I've just talked to my Service Manager and suggested that the front dampers and suspension computer be changed out. Since there are no error codes in the car, and I had returned the car already 3 times with the same complaints he has to get an OK from Jaguar to do that.

The vibration I have is very subtle, my wife can also feel it but, she says she could "live with it". I can not, as I drive the car long distances and that "micro"-vibration is absolutely driving me up the wall. I changed wheels and tires between the XF and the XJL and the XF is riding beautifully on the XJL wheels/tires. So, it is NOT entirely a tire or wheel issue, more like a chassis/bushings or damper problem.

Hope you find a solution and when you do, be sure to let us know of it.

Best of luck enjoying an otherwise incredible car,

Albert

Executive posted this video on the XJR some times back. I just got to see it and the tester makes a remark at 1:34 that sounds very similar to what some of us are feeling as a vibration. He mentions that even on smooth roads there is a constant "pattering" from the suspension. If this is "normal" on all XJ cars than, IMO, Jaguar really made a huge blunder. There is no way "pattering" or vibration or call it what you may, should be normal on smooth roads in any car.

My XJL going back Monday for the 4th time for, what sounds like, the same "pattering" issue. It simply drives me up the wall on longer drives.

Well, it does this also on my X350, the previous model. Of course, buying a used car, I just assumed it was a feature of the car ! This car is best on motorways or autobahns at 70-80 mph. On our country lanes here in the UK it can get very bumpy. Car has the 'Sport' air springs which are harder than the 'Comfort' ones. I am on 18" wheels, and the previous 20" gave a very harsh ride. If I can afford it, I may swap out to 'Comfort' springs but they are awfully expensive.

 

I got my car back today from the Dealer Service. In the report they did acknowledge that the ride was "abnormal" but, they did not find anything abnormal. Calibrated the suspension, reloaded the software and sent me on my way.

No difference, at all. The car's ride is just terrible. They put 37psi pressure in the tires which I immediately lowered to 28. Ride was still intolerably jiggly, full of vibrations over the very same road surfaces where my other cars ride quite acceptably. So, I lowered the tire pressures an other 3psi to 25. That made the ride tolerable, although still can not be called good. The chassis still vibrates over perfectly smooth road surfaces. One section of Interstate 80 had brand new pavement, only a few days old with shiny, nearly perfect finish. My car vibrated worse over that than older worn surfaces.

I do not recommend anyone to set tire pressures anywhere other than the factory recommendations. Having said that, I am not the least worried about the lower pressures. When I raced SCCA GT-class and formula cars my cold starting tire pressures on the tall sidewalled, superlight slick racing tires were 13-14 psi. Plenty enough to corner at nearly 2g. I did toss the XJL around my local winding roads at this pressures just to make sure that the tires were not deforming at these pressures and no, there is not the slightest sign of scrubbing off the surface of the tires towards the sidewall. These low profile tires have extremely stiff sidewalls.

I'm off for a month to the South Seas and have some time to think about what to do with this car. Should I hire an attorney and go for a Jaguar buy-back or, should I just bear it as I have been for nearly a year and a half? I got just as much until the end of the lease. Definitely the worst riding car I have ever owned. No way I would ever purchase an other one, no matter how much I love the looks and the stationary comforts of this car.

For the complete picture I need to say that I am not running the stock Pirelli Zero Nero tires. I exchanged them for the Hankook Ventus V12 after only 2000 miles of vibrations. I selected these V12s because they rode and handled well on my previous Jaguar XKs as well as on my present XF. They are much higher performance tires than the stock Pirelllis and do have stiffer sidewalls. That actually makes the ride actually stiffer, although quieter. However, the dealer did try changing to the stock wheels and tires but still declared the ride "abnormal".

Sounds like it is time to involve Jaguar NA, because the dealer has told you the ride is abnormal, so clearly it is not right and needs fixing.

You could also PM "Mike" of Jaguar, the Jaguar customer contact on this forum. Unhappy customers is not what Jaguar want, I am sure !

 

I definitely want to work on this with Jaguar NA, if possible. We'll see what can be done after I return from overseas.

Hello, I am a newbie on this forum! Hope my story helps.

I had the same problem with my car when I bought it in 2008. Thought that may have been the reason for only 20K kms on the clock by the previous owner. The original tyres were Pirelli P600s. Tried balancing many times, got annoyed, and replaced tyres with P zeros, and problem continued.
As vibration was also being felt in my seat, took the car to propshaft specialist, who confirmed and fixed the balance. That improved the car, but still had wobble in steering at around 80 kph. Higher and lower speeds were fine.
Went to a specialist tyre shop which does racing vehicles, and advise was that the tyres were impossible to force balance! Swapped to Michelin Primacy 235/50X18, original size, and have not looked back in years! Feel guilty that I have not checked out the balance in about four years! Will do so soon!

Incidentally, I was told by Pirelli Australia rep that the issue was tyres pressured high and shipped all the way from UK - a 30 day trip. And apparently, some European car importers swap tyres before sale to minimise such problems. Not likely to be confirmed!!

 

Hello Gillja, welcome to these forums.
Sounds like a somewhat different issue since you have the previous generation car. Still, difficult to tolerate when it happens.
I'm done with trying to fix my leased car. Jaguar once again declared it "normal" despite the last service visit calling the ride "abnormal". Well, if this is "normal" that means a sorry state of design and implementation standards from Jaguar. A luxury car that vibrates almost constantly over good surface conditions is an abomination.

I tried to get rid of my leased car but, it would cost me a fair amount due to the huge depreciation. So, I will keep it for the rest of the lease and treat it as my beater car, driving it with deep contempt every time. Shame on Jaguar for either producing a car like this, or failing to fix it.

 

I had noticed this mild, but unpleasant vibration in the steering wheel myself and working with my alignment guy. We found that setting the total toe in in the front to no more than 20° took away the vibration. I run Dunlap SP Sport Maxx GT's at 38#. By the way the Cat seems to corner a little flatter with the reduced toe. Hope this helps.

 

I'm glad that alignment helped you. Your quoted toe setting is, however, incorrect; it is usually measured in mm or fractions of inches and not in degrees. Even expressed in degrees it would not come near to 22. However, I could see that excessive toe could cause wheel vibration. That is not the case with my car, its alignment is fine.

 

Here is the printout from the alignment machine. Please note the front and rear total toe-in that the Cat handles like its on rails and there is not excessive jitter. I have one other modification in that I had the tech install the front sway bar that is used in the 2014 XJR.

 

Thanks for posting. I'd say it is not all that common to express the toe setting in degrees but, do note that it is way less than 1 full degrees (0.2 total) as opposed to what you said was 20 degrees. It works out to be about 3/32" up front that is within specs but, I would prefer zero or 1/16" there. That should produce an even sharper turn-in.

An other interesting aspect that Jaguar seems to set the camber in the driver front wheel less than the passenger front wheel. Even the specs call for such difference. I had found that difference in every one of my Jaguars so far, including in my newly purchased XKR. Not sure what is the idea but, they would normally set to be the same on both sides. I'm planning to have just that done when ever I get it to an alignment shop.

 

axr6 I tried .06 toe in and found that the turning was less responsive on turn in and required drive input in the turn as the car did not "rotate" properly as the sway set.
