Accelerator pedal vibrations?

Hi,

After 6 months and 10000 miles with my 2.0d f-pace sport, I've started to feel that my accelerator pedal vibrates, not strong vibrations, it's more a ticklish feeling, similar to the vibrations from the steering wheel, but compared to brake pedal (completely free from vibrations) and although they are subtle, you can definitely feel them.

I think these vibrations aren't coming from the motor, they reflect the tarmac condition: if it is fine you can barely feel anything, but if there are some strips, cracks or debris on it the vibration increases.

I'm going crazy because I cannot remember if they have been there from day 1 and this completely normal, but I started to pay attention to them after a slight cramp I felt on my right sole during a long trip and now I need your help if this is normal or if I have to really worry about it… Thanks.

Regards

I have a Tingly vibration on the pedal at around 1500 rpm. Only really noticed it when on a long carriageway at an even speed.

This will be "Drive Line Vibration " that comes in at around 1715 RPM 68 - 72 MPH and it appears when wear takes place on the drive line components such as bearings, bushes and the drive shafts themselves. In my case it appeared after around 7000 miles on my replacement F Pace but Jaguar engineering have now put out a directive to customer relations stating that this is a "characteristic of the F Pace" and as it is not a safety issue they will no longer entertain rejection of the vehicle or any realistic compensation. I wrote direct to Dr Ralf Speth with my complaint after my first F Pace was rejected for exactly this problem and although he was very polite in his reply telling me that his executive department would reach out to me to deal with my complaint they have just repeated that the driveline vibration on the F Pace is a characteristic of the vehicle. In other words Go Away!!
Watch this space as one of the motoring magazine editors have now taken up my complaint with JLR,asked them some difficult questions and we are awaiting some answers. I cannot live with this "characteristic " any longer and my F Pace is being traded for an AWD Sportbrake just being built.

The 2.0 diesel that I eventually got rejected had the vibration from new, although it did progressively get more noticeable, during the investigation the dealer supplied a loan car which was actually worse than mine. Yes, they supplied a worse vehicle to convince me that the vibration was normal and it seems that is their current line.
The 2.0 diesel does vibrate at 1700 to 2200 which is motorway speed, they all do that so it's perfectly OK.

Any new 2.0D owner should check very carefully when they collect the car and reject straight away while you have the best chance of success. It's not just the FPace either, last week I travelled as passenger in a friends 2.0D XF, on the motorway I could feel the same vibration, it seemed polite not to comment.

I'm not knocking the FPace as such, my present 3.0D is a very good car indeed but even that is not perfect, the second gear start off is just awfull, but I can live with that.

It is interesting that in the 1970-80s the vehicle manufactures all engineered out NHV harshness noise and vibration out of their products but now when it appears on JLR products in 2016-17 it becomes a characteristic and acceptable again. It is a fact however that this characteristic on the F Pace does appear in time and increasing mileage as most of the brand new vehicles and my Daughters new RR Velar seems still to be free of it after 4000 miles. Whatever Jaguar engineering say I personally cannot accept this uncomfortable new characteristic of the F Pace and my dealer agrees 100% with me but they also now come up against a brick wall when reporting complaints from customers.

I assume that this issue/characteristic is across the entire model range and not limited to the 20d, all 3.0 diesel variants, all diesels (2.0 and 3.0) etc.

I have only ever read reports of the drive line vibration being present on the 2.0 D AWD variants which was mentioned by the press reports from motoring journalists who tested the early launch cars in 2016. I am sure that other forum contributors will correct me if this is wrong but it seems the combination of the Jaguar built 2.0 D engine and the mating of the ZF gearbox and the AWD system is the problem which does not cause the same issue with the 3.0 D V 6 Ford engine.

The 3.0V6 drivetrain is essentially the same as the Range Rover Sport and very similar to the Discovery and other JLR variants, as such it is a well tried and tested unit that has stood the test of time. The engine is a fairly old design, my FPace is mostly smooth but has characteristic diesel clatter idling and some vibration at 1200 rpm, driving in sport mode almost eliminates that, as the car exceeds expectations in all other respects I'm pleased with it.

The 2.0D engine was a disappointment, not just because of vibration, fuel consumption was not great, overall it settled around 36 mpg for my driving, the V6 records exactly the same which is surprising because I do use the extra performance. Because of this I'm wondering was the fueling on the 2.0D wrong, however that's all history the 3.0D I can recommend.

So the petrol engines (2.0 and 3.0 litre) don't suffer from this issue then ? (Or not that anyone here has reported ?)

I have the 2L 180 D Auto AWD 2017 and have been most impressed with the performance having previously owned XFs with 3L V6 which were exceptional. I am returning 45mpg with mix of driving and have not experienced any pedal vibrations. Being an Engineer I am most sensitive to noise/vibrations and can only suggest therefore some kind of fault with your transmission eg tyres/wheel balance/ suspension bushes/engine mounts etc.

I have a brand new 3.0d that transmits vibrations through the floor. It is strongest through the foot rest, so I find myself moving my foot off it on longer journeys. The vibration is not related to engine speed, as it continues if I drop into neutral. It is almost certainly coming up from the road, and the severity depends on the condition of the road surface.

You are correct Carmad that the drive line vibration some of us have experienced is caused by a fault which developes in the transmission,drive shaft bearings or other components as mileage is added to the vehicle. The problem now is that Jaguar engineers are burying their heads in the sand because they have no solution to the very real and reported issues with the 2.0 D AWD. F Pace and declared that it has now become a characteristic and will not consider warranty on components or rejections.
Due to this unacceptable driving condition I have decided to ditch my F Pace in favour of an XF AWD Sportbrake but I cannot help feel that the recent attitude of JLR to a number of F Pace owners with real issues will damage the Jaguar brand and reputation.

I have a new 240D AWD Auto R Sport with only 1800miles on the clock and I have noticed the vibrations too. Usually only slight as reported above but noticeable all the same. I particularly notice it as the speed approaches 50mph and again at 70mph just before the gears change up, suggesting the gear change ratios may be wrong? Also noticeable if cruising with no accelerator pressure then applying pressure to accelerate brings on the vibration, especially if the engine has work to get up a hill just as you accelerate. It's mainly through the accelerator pedal, or occasionally through the steering wheel and can sometimes be felt if your knee rests against the central console. I liken it when its particularly bad to driving a manual in the wrong gear when you get that vibration/slight judder until you select the right gear. I'm of a mind to visit the dealer but comments above seem to say they will just shrug their shoulders. Has anyone taken it down the independent report route and had any luck?

I have a 2 litre D AWD and frankly I have not experienced any vibration on the pedals. The car has done 6500 miles since June and apart from the reversing camera sometimes not working, I have not had any faults at all. It seems to me, from reading this forum, that buying an F Pace is a bit of a lottery. There are winners and there are losers. I really do feel for some of you who have had such bad luck with this lovely motor. I have bought brand new cars for the past 35 years and usually change them every three years. I can honestly say that I have never had a lemon in any of them. Except for a Peugeot 607 I bought in 2001but that was one of the first ones in the UK and the dealer did not know how to deal with the problems.

With my 2.0d AWD R-Sport I don't get any significant vibrations from the floor and compared to accelerator pedal, foot rest and brake pedal are rock steady, and in neutral I have only a small vibration that I think is normal for a diesel engine (much less than in my old Volvo V40 diesel), but as you, the severity of vibrations depends on road surface.

These is very similar to what I feel, but in addition when speed increases over 40 or 50 mph I get an almost constant tingling from my accelerator pedal that changes it's pitch according to road surface condition, as if accelerator was directly linked to wheels (but as I said, brake and foot rest are completely free from these vibrations).
