2018 in the shop for second time in two weeks
I have a 2018 F-Type R Dynamic that we purchased in July that the battery keeps draining after it sits for 3-4 days in our garage. They said they fixed it the first time and it failed a few days later. We brought it in two weeks ago and they called and said it was ready after 4 days. We told them it needed to be 100% right because if not we would go the lemon law route which in Oregon if the same issue arises 3 times you can proceed with the lemon law process.
Well after a week and a half later they just called and said it was the Telematics ECU draining the battery and they replaced it. Has this happened to anyone else.Just a little gun shy as we spent a lot of money on a car that has us nervous of driving only to be stranded with another dead battery. Thanks for any input.

They replaced the battery the first time and said that was the problem. After I got it home I did the battery reset and it still went dead a couple days later. I feel like they are throwing darts at a dart board trying to see if that fixes it. It just makes us nervous taking it anywhere down the road. We only have a Land Rover dealer here in Portland that absorbed the Jaguar dealership in town. Not too confident with them so far.

Dang, Same Thing Started Happening to Me :(
Same thing just started happening to me, out of nowhere. A couple days ago, I walked into the garage and there was a faint dinging noise. I looked at the dashboard and there was a warning light “Battery Low, Start Engine.” So I started the engine and let it idle for 10 minutes. The next day (or second day), same thing. I had to go somewhere and drove 100 miles. We’ll see what happens. I’m hoping it corrects itself too. It worries me too because there are areas on the highway where there is no shoulder.
I bought the car in 2017 with that problem. The dealer changed the battery and the problem was resolved. Since then, the OBD port was accesses a couple times. Year and a half later it’s happening again
So I think I’ll disconnect the battery.
Another thing: Is this a false warning, or is the battery actually being drained?
Another another thing: I leave the headlight switch on “Auto.” No problem, right?
I feel ya, but its good to know I’m not the only one experiencing this.
I’ll keep y’all posted.
Edit: How do you disconnect the negative terminal? There seem to be a lot of things attached to it. There’s that copper looking thing and a black plastic thing to the side. Do I still just loosen the nut and pull up?

- NOT A FALSE WARNING. Battery will not be strong enough to start car after being parked for 48-72 hours.
- I leave my light switch set to auto and never touch it. No issue whatsoever.
- Disconnect the ground lead where it bolts to floor of the trunk. Easiest way to do it...nothing in the way.

If your car is not used on a nearly daily basis, and especially if this infrequent usage is combined with relatively short trips, the battery will not remain, or ever be, at full charge. The result of that will be electronic gremlins such as you are experiencing. The CTEK battery maintainer is designed specifically for these circumstances. The connector leads are permanently attached to the power source (there are threads on this) in the car; when you are not using the car you simply attach the CTEK unit to the connector. Done. It takes all of 4 seconds if you are slow, and it guarantees an end to electrical issues, assuming that you have a battery in good condition.
These units are sold by every luxury manufacturer under their own labels, from Bentley to Bugatti, including Jaguar and Land Rover, Mercedes, Audi, BMW, Maserati....and all for exactly the same reason.
Your car is telling you to get one of the CTEK units - al of them do the same job (but slightly differently). I have used them for years with 100% success.

If I look on the link, its a 15A charger.. .. you don't need that to 'trickle' charge a stationary car ! I bought a $ 19,50 12/24V 1,5A trickle charger and have been using it for years,
on my Discovery 3, Iseki mini tractor, LR2 and so on, and its fine ! You don't have to fork-out $ xxxxx amounts to solve this problem ! Yes, there is no handy fixed connection,
but when I store the car it stays for months at a time. Fixing is 5 minutes ; lead it through an opening that doesn'n clamp the wires [eg shutting the hood ]. No problemo...

If the use pattern of any modern luxury car is infrequent use especially if combined with short runs, then a unit of this type is an absolute necessity. Not using such a device almost guarantees eventual complaints.
The least expensive CTEK unit is all that is needed...if the cost is of concern to the Jaguar owner.

Dang.
I don’t think I’m the only one who likes hanging out in the car just to listen to music or watch a DVD. It would have been nice for a passenger waiting in the car. Kinda self defeating huh? I always wanted to mention that.
Oh well.......

No, it will not permit that because the car is programmed to shut the radio unit down after a specified period of time to save battery power (this is in your owner's manual...you have read it, right?). The fact that you have the CTEK unit attached does no alter the programmed factory power-saving mode. But it will ensure that your battery will be kept in proper condition.

You might be one of a few...but the fact that the car is programmed this way is the proof that modern cars (by no means only Jaguars) need full battery voltage - and this is one way to safeguard the battery power.
