Intermittent warning lights on dash

Hi guys, Im new to this forum and needing a little help.

I have a 2018 Cx3 2.0 120bhp sport nav.

Had it from March '18 and about 3 weeks ago a sea of yellow came up on my dash.. its all went off after a day but has came back on and not going off now..

Traction control, ABS, TYRE PRESSURE MONITOR, LANE DEPARTURE ECT..

Ive read that it could be dirty sensors or cameras so iv gave the car a good clean a few times and still no luck.. also been on 100-200 mile trips recently with heat on front windscreen to try and eliminate any condensation that could possibly be in with the front cameras..

Driving me crazy now :shock:

Photo of my dash is on this post.

I would book it in to a Mazda authorised repairer for them to run diagnostics.

I think i will JT as its bothering me the fact its intermittent something doesnt seem right.

I was hoping its just something silly but better safe than sorry i suppose. Due its first service in March but thats too far away to leave it. 🙄

My gut feeling is a faulty ABS wheel speed sensor or connection, but that's a guess.

In most cases, the vehicle electronics store fault codes that a repairer can retrieve and act upon.

How is the battery?
I know it's a pretty new car, but a faulty battery can make all theses fancy systems act funny.

But as jtonline says, on to the dealer and have them run diagnostics.

As far as im aware the battery is fine. Havnt had any noticable problems with it although now that you mention it,

Usually the push start button reacts immediately when starting the car.. i have noticed a slight delay maybe a second or two.. could this be battery related?

I had a loose battery connection on my MX-5 which caused similar problems.

Could very much possibly be the case.. to be honest theirs a limit to how much i know about cars and something so simple like disconnecting a battery and connecting it again is out of my league 🤣 its booked into Mazda for Monday morning so ill let the experts do what they get paid for i think..

Ill let you know the out come 👍🏻
