Bought a Xf, have had it for 450 miles, driving home last night car starts bucking, reduced performance and such. JOY, have it towed in to dealer.

They say that the previous owner must have used cheap gas as I need to replace ALL 8 injectors and plugs. total? $8500 for service.
I have only put about 1 and 3/4 tanks of premium into it.
Of course they found a half dozen other relatively minor things like front lower control arms bushings worn, they want to replace the arm but I see that I can also just get the bushing.

This is just crushing. 52k miles on the clock.
Just.. hosed.

The sad thing is that I had a meeting scheduled with the dealership to get an extended warranty next week.

 

Wow, that's some seriously bad luck, but sounds way OTT ??
Surely, if the car is that new ( albeit to you ) there must be some kind of warranty?
Usually buying a used car here in the UK from a reputable dealer you may get anywhere from 30 days, 3 months or even 6 months of warranty?
Have you checked that out in the first instance?


Contacts -someone here will no doubt drop by with JNA contacts shortly hopefully.
In the meantime you could try asking our Jaguar CRC (Ryan@Jaguar ) although his role is for the UK market, he may be able to pass your issues on to the relevant dept.


Good luck

 

I look forward to any advice. How do I even ask them to help?

 

Do you have any answers to my questions as above?


Check into the UK regional section and one of the top posts there is by Ryan@Jaguar, shoot him a private message or reply to one of his threads

 

No warranty Here in the states. What is ott?
So ryan@jaguar.com?

 

Over The Top

 

Sorry to hear your bad luck. Where did you buy the car - a Jag dealer? Or other mainstream reputable dealer? If so, the. You might have an argument to make. But if it's from just some 3rd party, you may not have any recourse

 

I'd see if your state has any sort of Lemon Law as we do here in CA. DMV is a good place to start. Good luck!

 

Initial response from jaguar (paraphrasing): Well, if you got a bad tank of gas then even though we admit to the car being just out of warranty, well... you can go pound sand.

All eight injectors failed (fouling the plugs) at the exact same time from "bad gas".
Dealership wants US$ 8500 for the repair.
Guess its time to crank out a slew of articles all across the net. Oh hey targeted advertising on facebook? Don't mind if I do.

 

That seems really odd....I have run into a tank of bad gas in some heavily boosted and custom tuned cars in the past (that are REALLY dialed in for a particular fuel) and although I got some bucking / hesitation and maybe even a CEL, it cleared out after I filled up with 93 octane. Have you tried taking it to an independent shop to get a second opinion? Did it throw any codes and if so did they give you an indication of what they were?

Just seems super odd to me that one bad tank of gas would cause that...unless it was a lot of low octane gas over a long period of time.

 

On tank 1.5 of BP Premium.
Went wide open throttle while passing,
car started to shimmy a bit then the "reduced performance" warning came up with the CEL light flashing amber.
Coasted for a bit and then pulled over, hesitation and performance got worse. Towed it to the dealership.

They said I had a lot of misfire codes and injector codes pointing to injectors going bad. "Several codes for misfires and fuel pressure found faulty injectors"


I ghost write for a few people on some popular auto blogs (great car guys but sometimes they need help with getting the idea into text). I was looking forward to doing some positive articles on the Jaguars in general, but I am no longer leaning that way.

 

Could this be carbon fouling from the DI setup? If it's gotten to the point where all 8 injectors are trashed, your intake valves/ports may be of concern as well.

Carbon build up on the injectors 2011 Supercharged.

Hope Jaguar USA offers you some assistance in sorting this out- the DI carbon fouling issue is a bit of a ticking time bomb worry for a lot of us.

 

Carbon fouling is a big issue for all DI cars, Audi, VW, BMW, Kia, Hyundai and Mazda for example (list is not exhaustive). It is an inherent design flaw and advice to run on gas without ethanol is not helpful when virtually all gas stations in my town have that corn junk added.

Someone here in Houston had an engine issue a few months ago and they also said all eight injectors went out at the same time, fortunately for him his car was under warranty.

Here is the thread

I'm no expert, but I presume the majority of the cost here is labour? If so, find yourself a good independent shop (ideally with some Jag experience) and try them for a quote

 

The injectors themselves are $280 as piece.


Seems more of an issue with carbon fouling.
Go wide open throttle, sucks the carbon into the injectors.

 

With DI the fuel pressure is now several thousand pounds per square inch. No way for carbon to get into the injector.

The carbon builds up on the back side of the intake valve because fuel is no longer sprayed at that point to keep it clean. Then this carbon can break off and go thru the engine. It can also keep building up until performance is reduced because of the restriction. Audi has been having major problems with this. Need to take the head off and de-carbon it like we did 50 years ago.

When you went full throttle maybe some carbon broke off and went thru the engine? Catalytic converters have burned up because the carbon gets lodged in them and then is burned off.

Still trying to understand how all 8 injectors could be damaged or go bad at once. That just does not make sense?

May I ask what dealership you went to?

You said you had it for 450 miles, how long of a time period we talking?

Every winter/summer season I try to run BG44K fuel treatment that a few members here use. Got rid of the little shakes/tremors/farts that the car was having.

Hope it works out for you.

 

Oh sure,
The car is at Patrick Jaguar Naperville.

 

Awesome, so they said I have a coolant leak somewhere. I said go ahead and find it, probably the overflow tank as per usual. NOPE. It is leaking "somewhere, and we think its in the engine", to be sure they would need me to authorize pulling the heads off of the engine to check. So the leak seems to be part of the culprit in the failing of everything else.
