I had to replace my battery in my 2016 LR Discovery in Oct 2018. I starting getting the same message again the past two weeks It would usually happen when I got in the car on short hauls. Then, I notice my rear door would not operate correctly so I took it to NTB where I bought the battery. They said it was fine but take the car to the dealer. Turns on that the battery was being drained and the braking module system had not been reset when the new battery was installed. LR service re-charged the batter and reset the BMS systems. LR told me that other places/shops probably dont have tools equipment to do this reset so you might as well just by the battery from LR anyway.



Not sure why you bought a battery since there is a 4 year warranty from Land Rover

Had the same issue arise on Friday. Every time I turned the engine off, I received the low battery indicator. Back hatch door would also not close electronically. Took it to local dealer this morning and according to them I have an alternator issue. They are replacing alternator and battery under warranty (2016 with 34K miles). Unfortunately with tomorrow being a holiday, and having to order a part, it’s not likely to be ready by Friday. So I have to go the weekend without it. And because I didn’t buy from the local dealer they won’t provide a loaner car, which sucks.

They should supply a loaner. I have had work done at 2 separate dealers and both supplied a loaner. Neither one was the selling dealer.


I bet they charge Land Rover for the cost of a loaner.


Put the car on charge and you can drive on the weekend.

My 2018 Dicovery sport only has 23k miles and always comes up with low battery. Is it a common problem

Hi all,

Few weeks ago my battery got all drained out of power (for no obvious reason), that i had to hotwire it, and then tow it to the garage (some systems, like break and transmission did not perform normally)...
They did all the service recalls that were needed (i own the for for 6 months), including the battery control module update (which they claimed is to be blamed)... They also checked the battery and it checked out "OK" in the battery gizmo, giving 780 something of power (Amps?).
But since it came back it keeps giving me the "Low battery Plesa start engine" warning every morning. There is no real problem, other then the warning and the fact that the start-stop system would not engage (which is understandable).
I do drive most days for 15 minutes to comute to work, and longer drives at weekedns (after a long drive the start-stop system does engage properly).
The garage said it is not a problem, and the cause is the short travel time, which doesn allow the battery to fill up.
But i have concern that it will go completely drainedout again (which was somewhat troumatic for a 6 mothns old and very expensive car), because there might me some kind of power "leak" during shutdown to some roug subsystem.
Has anyone experianced the same?
Any long term solution?
15 minute commutes are too short to keep the battery charged. You need to put it on a battery charger every few days or maybe at weekends.
The short commutes will also adversely affect engine life as it will not warm enough.
You could take it in a longer run every week, this may help.

Solved the problem!

It is the second battery. Here is a video on the solution and how to easily fix for anyone out there still having the issues!

Very interesting video I guess. But the Discovery Sport does not have a secondary Battery
