Are Jaguar XK8’s known to have continual electrical problems:

Here’s the story:

My car is a 2007 XK8 convertible, with a little over 100,000 miles on it. I got it used from Carmax, about five years ago.

I got an extended warranty, which is about to run out.

It’s been remarkably reliable, in that Jags for awhile didn’t have a very good reputation.

The problems I’ve been having lately seem to be electrical, seem to be related to the battery. I never had the problem the first few years I had the car. It seemed to start maybe a year ago, when the old battery stopped holding a charge, and the Jag dealer replaced it with a new battery. Since then, I’ve had a series of problems.

What happens is this:

1.  Occasionally, after starting up I punch the button for the radio, and it doesn’t come on.  Instead the antenna keeps cycling up and down part way.  Then, it won’t turn off.  Whether I punch the on/off button or not, it keeps cycling, about halfway up, then down, and so on…Sometime that happens after I’ve been driving for awhile, and later try to turn on the radio.

I found that if i pull over, turn the car off, and re-start, it almost always works properly thereafter.  

Until the next time, maybe days later.

2.  On other occasions, the screen in the panel in the dash that shows ‘backup cautions’, radio listings, or maps won’t come on.  Again, I found that if I re-start the engine, more often than not that ‘fixes’ the problem…for the time being.

3.  Last week I got in and the really weird thing happened:  I pressed the button to crank it up—it sort of started, then died, BUT, all the above started happening and more — the dimmer lights started cycling on off, the antenna was going up and down, odd whirring heard under the hood, and in the display on the dash an orange warning triangle kept cycling on and off, displaying a different warning each time, so fast I couldn’t read them.

I couldn’t get it to stop, no matter what.

I called AAA.  By the time the guy got there — maybe 20-30 minutes later — the odd stuff had stopped, the car was “dead”.

The young man decided it was the battery; hooked up his portable charger, and it cranked right up—with none of the funny problems!

I called the Jag place on Midlothian, spoke to Brian, the service guy, arranged to take it in.

He kept it for 4 days, wanted the battery to get low — see if they could duplicate the problems.

They couldn’t. Or so he said.

He got it last Monday, gave it back Friday — said there was nothing they could do, that the XKE years and model like mine were KNOWN to have such problems, that there was no fix, that maybe I could consider getting a ‘trickle charger’.  About the only good news was he didn’t change me, at least not right then.  He said he’d leave the ticket ‘open’, whatever that means.

When I cranked up the car, the radio wouldn’t come on, nor would the dash display screen.  I went back in talked to Brian; he just shrugged, that’s ‘a known’ problem he repeated.  I asked, since they’d had it almost a week, why they hadn’t re-charged the battery.  It’ll charge itself, he said, just drive it for half hour or so.

I was most annoyed- with Jaguar.  If there is/has been a known problem, you’d think by now they’d have come up with a ‘fix’!  And annoyed with the service, or lack thereof.

Jag user forums on the web do shows similar complaints.

I love the car, and hate to get rid of it … but, if it’s going to be unreliable, I may have no choice.

I’m told my a friend in the local British Auto Club that the Jag diagnostics are proprietary, and that I may have no choice but to got to Jag dealer.

What’s your advice?

Thank,

Jaguars HAD a very poor reputation for electrical systems waaay back in the British Leyland days before Ford bought them. Tata, an Indian company owns them now. In those olden days you would have had electrical problems from day one until you sold it. Your 2007 is heavily influenced by Ford and Ford’s reliability. That said, it is a premier car with fancy features, most of which are complicated and electronic.

Many complicated luxury cars (not just Jaguars) at 100,000 miles start to have small gremlins that cause the oddest of problems that can baffle even the best mechanics. A Jag specialist, which may mean “dealer mechanic” in your area likely will be required to fix the oddest of these problems.

If you wish to keep THIS car, you may have to embrace the fact that continuing to drive this car will take time, money and dedication. You will have to maintain a relationship with your Jag specialist to address a continuing string of problems. If you aren’t willing to make this kind of commitment, it may be best trade up to a newer Jag.

The problems are not brand specific but might be best addressed by a Jaguar dealer. Don’t have all the facts because I am not going to fight that scroll bar text.

The problem doesn’t seem to be the battery, I would guess that there’s an electrical fault somewhere–a failing component or some wiring issue–that’s causing an intermittent battery drain. I think your best bet would be a dealer or an import specialist with experience and training in Jaguar cars.

Those cars are loaded with high level electronics and have control units and wiring harnesses stuffed in every corner of the car. As a result, spilling a bottle of Gatorade in the trunk and it running into the floor panels can lead to electrical problems 6 months later.

There is nothing proprietary about Jaguar diagnostics. Any shop willing to purchase the equipment, software, service manuals, and wages for an experienced technician can fix your car. Most shops won’t make that investment though, as it’s unlikely to be profitable without a large client base.

If you’re driving a 10+year old EuroLux car, maintenance and repair costs can’t be a significant concern. Thousand dollar repair tickets will be a common thing.

We recently had a 12 year old Land Rover in the shop, the complaint was that the battery would be completely dead after sitting 3 days. A somewhat complex diagnosis led to the discovery that the A/C control panel was faulty and constantly drawing current. It needed a new battery and an A/C control panel. I didn’t bat an eye when I gave the estimate of $2400 and neither did the customer. Just another repair ticket.

I’m with Volvo on this

It’s hard to read texts where you have to keep switching back and forth, between scrolling left/right and up/down

Thanks for the prompt response. Which, sadly, pretty much describes what I’m facing. As much as I enjoy the car, and the head-turns and compliments, I’m not sure how willing I am to put up with the ‘unreliability.’, nor the ‘attitude’ from the service rep. He probably doesn’t have time for ‘hand-holding’, nor ‘tea and sympathy’, but what I’m considering as a replacement is NOT a Jag, but perhaps a Porsche or a Mercede or BMW two seater convertible.

Thanks again,

Hal

That certainly will assure that you have expensive repair invoices. Maybe you should look into leasing and not buy used.


#8

I don’t see any problem with buying used… like he did with the Jag. Go to CarMax and buy the extended warranty on the car. Keep it 5 years and move on to the next one. Might be cheaper than leasing a new one.

Always remember Doug DeMuro’s Land Rover… :grinning:

This one required scrolling right and down. I could only see fragments.


#11

You have an extended warranty, is this being covered by the warranty?


#12

Thank you so much!
I’m new to the forum, first posting. A lot to learn.
Again, thanks!
Hal


#13

Yes, there is an extended warranty, but since they did nothing–except pronounce it a ‘known’ problem with older Jags–they left the ticket ‘open’, whatever that means.


#14

" I didn’t bat an eye when I gave the estimate of $2400 and neither did the customer. Just another repair ticket."

Me, I don’t like repair bills, hence the extended warranty. But they didn’t charge me – so far. They kept it on an ‘open ticket’.


#15

This one came from CarMax, and I got the extended warranty–which more than pair for itself. That’ probably my first option this time around.
