Wobbly rear end (lateral suspension issue)

Moving this discussion to it's own thread.

Who is experiencing this? So far I have (other than myself):

RaVoIVoR
F-Pace S

For those who've not followed other discussions in various posts the problem is best described and a significant lateral (side to side) movement of the rear end of the car. The front feels tight and stable, and the rear feels suitably firm in a vertical (up and down) direction, but unstable in a lateral direction. A succession of asymmetric movements of the rear wheels sets it off, such as speed humps at an angle, or a series of undulations. It's worse at slowish speeds (5-20mph) and the movement is quite pronounced.

I suspect it's only those of us who live in very urban situations that notice it. For example there isn't a street within 5 miles of my dealer in Coulsdon that sets it off, however there are 10-15 streets around where I live in Wimbledon that do. I've even changed my normal route to bypass such streets.

I was in Brighton at the weekend, and found a few streets there too. If I didn't live in a very urban environment and only encountered it occasionally I would easily shrug it off. It feels very 'out of character' for the car that most of the time has a very firm feel. Engaging Dynamic suspensions helps quite a bit (but doesn't eliminate it) but the whole point of a "normal" suspension setting is to improve comfort in more urban surroundings.

My dealer is shrugging their shoulders, but trying to help. They are organising a technical to home to my home for further investigation. I am convinced it did not occur on the first two hours I had in the original demonstrators, but they have since lent me their new demonstrator and that's identical, so I don't believe I have a fault as such, but I do think something has changed in the way the suspension is set up.

If you are experiencing this, could you PM me, as my dealer has told me the best approach is to get enough people to ask their service department raise a "quality report" with JLR.

Thanks all

Agreed. I am now almost enjoying urban driving. It can still get thrown off by a series of bumps, so there's always some anticipation and being quite precise over urban obstacles and very bad road surfaces, but I can live with that.

Now that it doesn't bottom out over speed humps, or throw the rear end in the air (the dog is much happier!) I'm less apprehensive and chucking it about a little more. Not in the same way I could with the Evoque, but vastly improved over the way the previous one handled.

Passengers have even commented on how comfortable it is, which they never did before.

And they even compliment you on your choice of footwear! :eek:

Today I am wearing a very natty set of green trainers! They would match Yorkie's car beautifully.

I had a bit of a think last night. My new car rides exactly like the original demonstrator that I took out for two extended tests. So I'm not so sure that Jaguar has done anything consciously to modify the suspension behaviour at all. I think I might simply have had a fault with the adaptive ride on the old car. Yours could be an intermittent fault Corrie's Dad?

How many more colours do you have lurking at the bottom of the wardrobe?!

I agree, mine drives how I expected after the test drives, but it wasn't intermittent... It has never worked from new. Changing modes made no difference.

I don't believe it is a coincidence it just started working on it's own after being at the dealer.... unless there were little chocks in the springs that they pulled out!

It seems to be stiffer in eco mode... Is that correct? I've tried to find out via the manual & online info but no joy - only configurable between Dynamic and Normal settings mentioned

I was told there's no change to the suspension between eco and normal.

I can imagine if there's a fault that it was triggered by something they changed/updated.
It has to be something to do with the update, though he denied that a suspension fault would be to do with ICTP - again something I find hard to believe.

It is strange that mine seems stiffer in eco than normal. It wasn't just me but the passengers that could feel the difference too.

I'm glad it works, but it's that sickening feeling when you say somethings wrong and they say, ' nope we've checked it out and it's all fine'. Reminds me of the nightmare Range Rover that I ultimately had to reject.

It's probably another reason not to be first with a new model..... the dealers don't have a clue either, but few ever admit it...

Hi all, Can you tell me how you got this resolved. My f pace has a dangerous wobble at speed more noticeable over 70 mph but also does it at lower speeds. Model F pace 2.0 Prestige 17 Plate. Dealers had it 3 x but say no fault. Now got to point where I am not confident to drive on motorway as it is dangerous but they are saying they wont test it over 70 mph. I take this vehicle abroad so now at stalemate with them. (They also said it was due to roof rails !!!!)

Not sure if I have the same issue or not, I don't have adaptive dymanics, but the rear of my car does appear and feels very loose going over uneven roads, I get a lot of squeaks and if you sit in the rear seats you can see the tailgate moving in its opening, it is like there isn't enough structural integrity in the rear to prevent the movement. The dealers did try to adjust the tailgate to shut "tighter" but this had no effect.

Mine seems ok , no adaptive, no squeaks either , suggest dealer to check rear bushes etc.
No tailgate movement either that I can see. I suppose it depends how rough the ground is?

Just picked it back up from the dealer after they had it for more than two weeks. They fixed the ictp connection problem with a new telemetry? Unit. But if anything the squeaks, rattles and groans are worse. I'm not sure what to do next. Part of me has doubts that I may be being too picky, but the noises and feel of this car is far worse than I had in my 10 year old freelander. I think I need an extended test drive in another f-pace to compare how the rear end feels and sounds. The dealership just doesn't seem to be set up to find all of the noises I get just driving 10 miles.

Does anyone have any suggestions on how to escalate this, after driving home tonight I am considering getting them to buy the car back, but now that it's more than 6 months old I think I will end up losing a considerable amount of cash.

I have the exact same issue at low speeds in a bumpy urban setting at less than 50kmh

increasing rear tire pressure helps but does not fix the issue

Pirelli P zero tires on 22” SVR.

Dealer said rear suspension arms. Replaced but did not fix the issue

please advise. Any help would be appreciated
