Has anyone with this model experienced a noticeable vibration between 70 and 80 mph? I have Pirelli P Zero Nero tires fitted. Jaguar dealer has checked balance and cannot explain cause of this vibration. Might be helpful if any one has the same experience. Thanks.

 

Scott,

This is not rocket science to diagnose. If I were you, I'd find another Jaguar dealer because I doubt that he did a complete and thorough inspection. How much did your dealer charge you?

What size/brand/model of tire is on your car? How many miles on (1) the tires and (2) your car? Where do you feel the vibration, in the steering wheel or your seat or both? Do you feel it only when you're applying the brake? High speed vibration can be caused by either (1) the tire itself or (2) the car.

Mileage
The higher the mileage, the more wear. Vibration can come from (1) tires that developed flat spots or uneven wear patterns and/or (2) various front and rear suspension components (tie rod ends, bent rims, rotors, etc.)

Where Felt
If you feel the vibration only in the steering wheel, it's caused by something in the front end - either tires, suspension, or both. If your steering wheel doesn't shimmy, and you feel it in your seat, it's coming from the rear - check the suspension components, wheel integrity, and the tires. If you feel it when braking, you have one or more rotors (brake discs) that needs to be resurfaced or replaced.

Tire
1. First, make sure that (a) all the tire pressures are within spec; (b) all that the wheels are not bent or cracked and run true; and, (c) that all the tires are round (check b and c on the balance machine).
2. Balance results can vary depending on the brand and model of balance machine.
3. Check for all tires for uneven tire wear; insides/outside/center, cupping, chunking, etc. Could be signs of inflation and alignment problems.
4. Even if balance checks out, there could be a separated belt - but that usually shows up when balancing.

Suspension
Your Jaguar dealer should know the suspension/brake components better than anyone else. Did you get a written report as to what items were inspected by the tech? Did the alignment check out? Was brake rotor runout within spec? Was there any excessive wear on any front/rear suspension components?

I'm not a tech, but I learned the above from many years of experience as a shade tree mechanic, long before a computer was needed to work on a car.

I have this model/year and have not had that problem. Sorry I could
not be of help.

 

Check your transmission mount. I had the same issue on my X350 and that solved it. I believe the X351 has the same mount setup.

 

Has anyone experienced brown oily stains coming from the air condition'g condensation when you switch off the engine? I have been told by my jaguar dealer that it's coming from the condensation dripping onto the heat shield they have replaced the heat shield but I am still getting brown oily stains on garage floor?
This has only started to happen in the last couple of months, never had the problem before and this is my second 2012 XJ ?? Any help will be appreciated.

 

With respect to the tire issue, I have two questions. How many miles do these tires have on them, and are they original to the car? Up until recently, when some "jackass" rear ended it, causing it to be totaled, we had a 2012 XJ-L Portfolio. We were the original owners, having owned the car from the first week in January, 2012, through the end of July, 2016. At the time of it's destruction, it A) had the original tires; and B) they had 12,500 miles on them.


The car was stored winters, with the tires inflated to 40 PSI, and sitting on 3 "squares" of carpeting, under each wheel. We never had any vibration issues. But having said that, assuming the car HADN'T been destroyed, I probably would have considered replacing the tires next year, simply due to age.


In the OP's case, two things....does the vibration come up through the steering wheel, or the seat of your pants? Steering wheel, I'd be looking at front wheel balance. Seat of the pants, maybe rear tires, or elsewhere in the drivetrain. If you suspect tires, I'd look for a shop that has a Hunter Road Force balancing machine, and take the car there. You can look up locations on Hunter Engineering's website......unless, of course, the tires have a lot of miles on them. In that case, I'd be shopping for new ones.

 

I recently had vibration issues and it turned out to be my motor mounts and transmission mount. All 3 were replaced and now no vibration. It was easy to see there was an issue with the motor mounts when you looked at the air intake tubes as the corrugated part of the tubes on both sides were pinched together on the top. Now that the mounts have been replaced those tubes are evenly spaced top and bottom both sides. I, also, might add that I have had issues in the past with some Pirellis and that was resolved when I had a 4 wheel alignment done and they changed the "total" toe in.

 

Different car, different tires but I had a similar issue on my 2015 XF with 19" conti's (slight vibration between 70 - 80)

First trip to the dealer, they road forced balanced and alignment. Was a little better but still present. Second trip, another service advisor told me that there was a TSB out for my car / tires regarding fixing flat spots on a tire.

They deflated all 4 tires to 28psi, then drove the car 30 miles. (I suppose this rounded out any flat spot?) Re-inflated, road force balanced again and is now just about perfect.

 

bent rims can also cause vibrations. the bends can be on the inside of the rim, not jut the out

 

I have a 2012 XJ Base but with Factory Portfolio Upgrade. I am looking to replace my tires which are Pirelli P Zero Nero 19" wheels. I'm not a fan of these tires I find them somewhat noisy, so I wondered if anyone has suggestions for an alternative brand. I want All Season good traction and quite ride, as I live in Florida so Snow and Ice are not a problem. I have been checking out BF Goodrich G-FORCE COMP-2 A/S which get good reviews from Tire Rack has anyone tried these tires on a 2012 XJ ? any other suggestions will be appreciated

Thanks

 

Scott, I had the P Zero's on my car when I bought it and then switched over to the Continential DWS-06 tires. Better ride, better traction, and were cheaper than the P Zero's. That would be my recommendation. A lot of people here have used the tires with similar results.

 

Thermo, are the DWS-06 tires quiet? Currently riding on 20” P Zero Nero’s. These pick up some road noise.

 

michaelnv, I have no issue with the road noise and I would say that the DWS's were quieter than the P Zero's when they got pulled off of the car. I don't really hear any road noise with the DWS tires. Granted, normally the only road noise is when I goose the car off the line and get a nice little chirp out of the tires. he he he he he he.

 

Pirelli's are known for their road noise, especially their summer tires. I've heard that the ExtremeContact DWS 06 is a good replacement, but they are a no-season tire that is no use to me in the desert SW.

 

I like the look of the FIRESTONE FIREHAWK INDY 500 also has excellent reviews, Has anyone with 2012 XJ had any experience with this tire?
