Trying to put together a list of known XJ (X351) problems and approximate cost of repairs. The numbers are from Internet and for some are total of labor+parts. Not sure about accuracy or YMMV.

Feel free to contribute or correct.

• Water pump and cooling pipes- 900 (labor) 250 (part)
• Timing chain, Tensioners and guides (labor hours anywhere from 15 to 20) - $3800
• Front top strut mounts
• Front sway bar bushings and ball joints wear - ? (a very expensive job) ($700 in parts)
• Front control arms - 2,300 (set of 2)
• Front shock absorber - 700
• Sunroof rust - 3,500
• Freezing door lock / cable - ?
• Oxygen sensor malfunction - ?
• AC compressor failure - $2,000
• Steering rack replacement - $4,000
• Leaking Rear Air struts - 1,500 (one)

 

The AJ-V8 has timing chains, not a timing belt.

 

I don’t think all of these are so common...

A more appropriate title could be:

« List of common and uncommon XJ problems and cost to repair »

or

»

« List of known XJ problems and cost to repair »

 

Drop the rear air struts. They are not a common failure.
AC also not common.

Really should be listed in order of probability. So put the water pump first.
Outside of that nothing stands out? Timing stuff is year dependent as changes were made as time went along.
Maybe add front top strut mounts? We are seeing more of these with age and miles.

Isn't there some issue with cooling hoses, on "early" XJs, with the V-6?

 

What year and engine are we talking about? The issues became less with newer models.

Can add the sun shade motor/ guides/ anti-rattle kit - I think it was $1400.

Sticky buttons - lots of elbow grease

supercharger coupler/ snout - ~ $1000

Vacuum pump oil leak - $???

Sunk coolant reservoir float - ~ $350

Fuel injector clogged - ~ $400

 

If you're referring to my post, the car is a 2016. My dealer's sales manager made me aware of the problem, and told me to "be prepared",,,,,

 

The coolant hoses in general are prone to leaks in this car. The hoses were “rerouted” somewhat to reduce leaks. I think that was around 2016. I did mine at an independent shop and the price wasn’t too awful. As it was part of a larger service I don’t know the exact cost, but would guess around $1000 including a new water pump.

 

Lol hoses weren't rerouted. They went from a two-piece formed together design to a single molded pievce design. They always leaked through seam in which the two pieces were melted together.

 

Im referring to the attached list of parts; call it what you'd like.

The attached file is from post number one here, where he details the update list pretty clearly.

All the best.

 

$1000 to replace a faulty design by the manufacturer, and replace a water pump that on a Ford or Chevy, would last 20 years, or 200,000 miles. WOW....................

 

Yes if you need to pay for service it's very expensive. I can only own my 2014 XJR because of this list and I try to DIY the repairs.
Otherwise just too expensive.

I agree, but one of the issues that I've incurred over the years, by doing as many repairs as possible by myself, is a couple thousand dollars in "specialty tools", that are car specific, and most likely, used only once.....

 

The only thing I have that's Jaguar only is SDD. But I had a spare laptop and the software was free but did take an awful lot of time to get it set up and working.
The Mangoose cable was about $60. Other than that I can't think of any special tools? I just use my regular hand tools but I have not done anything real technical like the timing chains as I do see a number of specific tools for that repair.

These modern cars have forced me to purchase an oil extractor and a fluid pump to help with servicing the transmissions,rear ends and AWD gear boxes. Many times there is no drain plug and I just don't believe in "lifetime" fluids. I change them all! That extractor has made difficult jobs a breeze!

Your list of "known XJ problems" is based on what? I never had any of these problems with my 2005 XJ8L. I replaced it at 117,346 miles due to it being totaled in a parked car accident. I currently have a 2014 XJL Portfolio AWD and have not encountered any of your "known XJ problems." Please share with the forum your source verifying this list of "known XJ problems." Thanks.

 

Some of this stuff is well known (just use the search feature), some is not common, and some is not a flaw. Most importantly though, it all depends on the year and engine of the vehicle.

For example a 2014 will doubtfully have the sunroof rust or rattle as those were improved prior to 2014. Sticky buttons were allegedly dealt with in 2016. Timing chain tensioners were improved somewhere around 2013/2014. NA engines don’t have SC couplers. And my 2010 doesn’t have stop start batteries to deal with. So discussing “common” issues is difficult when they are not common to all models.

The stuff I don’t consider common, or that is not a flaw:

- suspension wear (wear and tear items aren’t really issues, except perhaps the strut mounts)
- AC condenser
- oxygen sensor malfunction

Another couple items to add though are:

- broken seat heater piping
- speaker wire rattle in the doors

A better question would be at what mileage should the timing chain be changed?
