Hi,

I've read a lot of positive things about this forum so I hope you'll be able to help me.

I am the owner of an 2013 F-Type V6 with 380 horsepower and everything was fine with the car as of recently when it started behaving strangely. So, here goes my horror story.

When driving in a city, whenever there is a stop and go traffic i.e. where there is a lot of braking and accelerating after a while I receive various error messages that are almost always accompanied with the power loss. After that the car usually doesn't want to change the gears and I always have to turn it off in the D gear.

After I turn off the car, in most of the cases I can't turn on the ignition as it seems that it is dead except for the displays that seem as if the car is booting up (only the Jaguar logo is visible). Usually, it takes about 30 minutes for me to be able to turn on the ignition.

Though, when the car starts, there is a yellow check engine light (CEL) turned on. Since I don't drive the car with the CEL on I wait for another 20-30 minutes and when I start the car afterwards the light usually goes away.

I thought it might be a battery so I bought a new one but the problem persists.

Also, the error messages I've been getting are different and I don't think they represent the true condition of the car. I get from Gearbox Fault, ABS Fault, TCU Failure through Roof Latched and some other messages

Has anyone else had such problems?

I'll post some videos later where you can see what I'm talking about.

 

Car won't start

"Gearbox fault" message
Note: everything is perfectly fine with the gearbox (it was checked by the ZF specialists)

X-Mas lights on the dashboard, can't change gears (lever isn't even lit up)

 

sounds like you need a new battery. Low battery causes all kinds of problems with this car.

 

I have already tried with a new battery but to no avail.

 

I think we need to see the codes involved?
Can you get the car scanned?

Sure, I hope this will help. I think these are the most important ones.

But did you make sure it was fully charged when you installed it? New batteries are often less than fully charged - mine took an overnight charge on my CTEK to be ready.

 

Battery, Battery, Battery. Fully! Charge it. then get a maintainer and use it. I spect it should be happy days from there on out.

YOU do not have electrical problems.

 

True, true, I didn't check if the new battery was fully charged. Ok, I'll give it a go. Thank you guys, I will keep the topic updated.

 

It's a cheap fix if it works, and if it doesn't you'll at least have eliminated one possibility.

 

I agree. All those U codes are network errors and very rare unless you have major wire harness problems. Like in a wreck.
Let us know how it turns out.
Betting it's a battery problem!

I just wanted to update you on the current status. Well, I don't want to jinx it, but, I haven't had any problems since I had the new battery charged overnight. I did some 40 km (25 miles) in the city and there were 0 problems.

I'll keep the battery maintainer on whenever I have the opportunity as suggested.

There is still a possibility that there is a zombie battery drain, but that is yet to be diagnosed if there is anything to be diagnosed at all.

Thank you guys for all your replies and help!

I've been having similar sort of issues with my '17, coupe MT.
Started with totally flat battery after driving 450 miles to Richmond, VA, and not using it for three days. Had. jump start from a friend and drove back home.
Next morning after locked and in garage, battery was 90%. Then 95% next morning still garage with 20 minutes on maintainer the previous evening. Off to Jag techies for week plus. They updated software on GCM & BCM which were out of date. They said all seemed fine. Had the car back on the 6th May. Then...

6th May back from Jag after GCM & BCM software updated.
7th May - Battery 82% after 28 mile errands trip. Stopped three times. Noted left rear number plate light flckering. Left on maintainer for 20 mins - 95%.
8th May - Battery 87% in am.
9th May - Battery 95% in am. After 52 mile trip. 85%. Left on maintainer for 20 mins - 95%
10th May - Battery 60% in am. Left on maintainer to 95%. Errands in afternoon battery 77%.
11th May - Battery 70% in am. Left on maintainer to 95%.
12th May - Battery 95% after maintainer. Short trip 72%.
13th May - Battery 80% in am.
14th May - Battery 77% 10am. Left on maintainer.
15th May - Battery 95% 7am. After 280 mile trip (Rallye for A Cure) 95%.
16th May - Battery 85% 7.50am. 35 mile trip 95%.
17th May - Battery 67% 8.30am. Trip back to Jag.

Still at Jag with techies...

 

Your battery is probably defective...the fact that it was "totally flat" at one point suggests that it is no longer capable of retaining a full charge (and these cars like full voltage all the time). But in addition to getting the battery issue solved, you might want to consider the possibility of OBDII port drain. One would assume that your dealership is aware of this and does not leave systems running after removing the OBDII connection, but....
At the very least you need to disconnect the battery, leave it for 30 seconds and reconnect to reboot everything. If, however, your battery is indeed defective, the problem will not be solved.

 

Well, that is unfortunate. Have you tried changing the battery?

From my personal experience, Jaguar workshops are often not the best place to get the issues resolved. I mean, my problem should've been diagnosed by Jaguar, but it seems that forums are almost always more knowledgeable than they are.

 

Seems to be the way to go... Battery is certainly not retaining charge after runs and drains overnight, locked in garage.

 

But why is that? Doesn't seem logical. Surely JLR would train tech's to be all round thinkers and to even do a reboot, as suggest above.

 

Forgot to add the 'Flickering number plate lights have not been replaced yet as they want to check electric lines to make sure it's not the rear plate lights...
these tail lights have condensation in both. Tap them and they flicker and/or go out.
Are these lights LED's? In which case, there wouldn't be enough power to drain 15/20% of the battery over night surely?

 

I would think that JLR would start by checking your flickering rear lights. Condensation in rear tail lights should be addressed by Jaguar. I had a battery drain from the baffle button, that was corrected and no issues since. They had to go in the rear area by removing panels and fixing the short. I cannot understand why the dealer is not correcting your rear light situation, it appears to be shorting out somewhere. Good luck
