All is fine but Dash Light ?

[Eamon McAtarsney 0]

Hi all,
I recently bought a 2016 HRV Dsl.
The attached dash light pic comes on every now and again and can stay on for hrs too.
I have replaced the battery in the 1 key fob I have with a quality new battery.
I have charged the engine bay battery to 100%
All that has been done lately to this vehicle is a standard oil change & basic service after time of purchase.
Light came on a few weeks later. 
Another problem is every now and again the main screen for Sat Nav etc has to be restarted due to low battery message ?
So...whats up folks ?
Is it a main engine bay battery needed or ?

Hi

 

I would go and see if the car can spit out any codes to what the issue is. There could be many reasons. Is the car still under manufacturers warranty?

Just a thought but have you got the key in a Faraday pouch and the signal is being blocked ?

Brought to my local guy and he cleared 1 fault and light stayed out for a day and then back on again so not sure if it was just an fluke as the light is interment ?
Doing some more research and the engine bay battery is an L2 60Amp when local autoa parts dealer says it should be a L3 70 Amp 
Could this be my problem ?
Talked to 2 Honda dealers and they are none the wiser ...just give us £95.00 and we will plug it in and see ....
A new "Gell" type L3 battery is £100 
Decisions ?????

Next problem ..I only have 1 key and no Pouch in the situation.

Definitely sounds like a trip to the dealership with your wallet as I cannot think of any other explanation at this stage
