Multiple warning lights and transmission sign blinking

[minion]

Hi, my 2015 Auto SE just started concerning me. I took it for a short drive (10m) and parked up, came back 45 minutes later and when started the lane departure alert and collision detection alert were on permanently and the transmission symbol was blinking, I drove home and the problem continued, I cleaned the windscreen even though it's clean anyway in case it was a sensor issue and it is still doing it, any ideas what might have happened please?

Have you tried removing the negative battery terminal for 10 minutes or so to reset the system?

Resetting the car’s electrical system quite often clears the problem on modern cars but why it happened I don’t know.

How old is your battery?

I only bought the car in august it had one previous owner, for all I know it could be the original battery which would make it 10 years old, I'm going to try and get the car serviced soon at a honda garage so hopefully they will be able to test things like this, this is my first car so I've never done any of this before

30 years ago it was very unlilkly a battery would last 10 years.  Then with improved batteries  and the fact modern ECU controlled engines tend to start efficiently 10+ years was not uncommon . In recent years cars have so many electrical systems and computer systems running 24/7, stop start systems etc  batteries are struggling again.   
 
Disconnecting the battery is a like  switching a  computer off and on again.  It reboots the cars computer controlled clever tricks. 

You might be able to tell if the battery is original from its brand.  If its a make you  have never  heard of its   more likely to be original than  well known european replacments such as  Bosch etc . (But some Japanese brands  such as Yuasa are sold in the UK) 

Having the battery diagnosed and, if necessary,  replaced by a reputable  Battery specialist might be a cheaper option than paying main dealer price.   

If you typically  only do short journeys  starting the car might take more  charge   out of the battery than gets  replaced  by the alternator during the short drive.    Even a new battery may struggle to cope  with repeated short trips,especially in the winter when there is extra demand from lights, heater etc plus batteries are not at the most efficent  in cold weather.     If this applies to you consider  occasionally trickle charging the  battery with a smart charger. Or if the car has no access to mains electricity make sure it regularly gets a decent long run to help charge the battery.  . There may be other options that would help  such as solar charger.

A rough & ready battery check is whether the stop/start is working. If it is, then it’s unlikely you have a battery problem. But if it isn’t, and the multi-function display shows a battery symbol, then that indicates the battery is not up to scratch. It’ll probably still start the car (and may continue to do so for months if not years), but it indicates the battery is past its best and you need to plan to change it.

Yeah the faults are back and I have seen the battery warning sign you get sometimes when it says the stop/start won't work before (the one with A/C crossed out). I have booked Jeffrey in to get serviced at the main dealership and told them about the faults so hopefully they will take good care of him and fix his issues.

[ColinB]

Yup, definitely sounds like new battery time. Make sure you get one that's designed to work with Stop/Start.

Incidentally, the A/C crossed out as a reason for the S/S not working is misleading; it works perfectly well with the A/C. But the S/S doesn't work if you have the vent system set to demist the screen (knob all the way to the right for a manually-controlled system) and that's when you get the A/C crossed out symbol.

Well the garage have said the warning lights were due to the rain sensor being obscured due to recent frosts! I did actualyl try and clean the windshield as I wondered if the sensor had anything to do with it but being short I obviously couldn't quite reach the sensor area.  There were other significant problems though such as the caliper being seized on the front left wheel

Sounds unlikely to me. The sensor pod can get condensation or frost inside, but my experience has been that when this happens various driver aids just stop working. I've never seen anything like you describe. And if the alleged obstruction is on the outside, that's within the swept area of the wipers so even if you can't reach it, once the car's defrosted it'll get cleared.

[UKjim]

I agree with Colin, most unlikely

You're both right, they called me back said the warnings had come back and did a further investigation and are saying it's a sensor in the gearbox that's faulty, only the sensor.
