Hello all,

We’ve a 2018 CX-5 Akera (2.5l petrol) and recently began getting some odd electrics related behaviour.

1. The driver’s side mirror will not retract (neither automatically nor with the manual selection). The passenger side one retracts and extends automatically on engine shutdown and start up. I’ve been through the reset procedure several times to no avail.
2. The driver’s seat has lost its memory setting ability. Again, been through the setting procedure multiple times to no avail. The seat needs to be driven to the desired position (using the controls mounted on the side of the seat) for a drive after which the car is parked and locked. Upon returning to the car and opening the door via the remote, the driver’s seat will spontaneously run to the rearmost position and has to be positioned back to the desired driving position – again with the seat mounted controls.
3. The temperature gauge used to religiously sit a smidgeon below the 100 degree mark – summer or winter, a/c ON or OFF etc - but of late has (a) only risen to around the 80-90 degree mark and (ii) varies in temperature for no apparent reason (e.g. unlike coasting down a long hill where I’d expect it to cool a little etc) by jumping a tad cooler then jumping up again whilst in a steady state of kmh/rpm.

So, has anyone else had any of these symptoms and, if so, what was/were the fix/fixes?

Are OBD readers capable of detecting electrical faults?

Any and all comments and suggestions welcome.

Thanks.

 

How old is your battery? If it's the original then it's definitely on its way out.

 

Alexmed2002 is going in the right direction to do first.

The battery no matter what the age could effects all those noted battery powered supplied parts and systems if the battery is in poor state of condition.
No matter what the age the battery it needs to be load tested first before any further electrical trouble shooting is started.

 

Thanks.

Battery is less than 6 months old but worth getting checked.

I'm intrigued, though, that only one mirror is affected. Would they not be on the one circuit?

Nonetheless, any further ideas most welcome so that I've an itinerary of what to check after the battery.

 

the age of the battery even on the shelf at the retailer has nothing to do with its health.

it not a point of worth getting it checked to would be the first thing a good service shop would check first.

When I get a customer in the service shop with an electrical issue I take 2 minutes look at the 4 connections having to do with the battery and do a load test. The next thing is a 2 minute scan of the ECU.

 

Battery tested OK at the auto-electricians this morning.

Where to next?

Still intrigued why only one mirror has stopped working as logic says they are on the one circuit. The owner's manual seems to indicate only a single fuse for the mirrors, not interdependent fuses. Fuse 10, 7.5amp which tested OK with a multi-meter. It was replaced with a new one but the immovable mirror problem remains.

 

Next is check for power to and at the switch . The switch you may need to disconnect it to perform basic continuity test.

 

The switch that puts the mirrors stowage/deployment into auto or manual can control the passenger side mirror in manual. No switching can get the drivers mirror to move. That would indicate that part of the circuitry is fine at least.
