Have 2013 b max that has done 34000 miles. Essentially electrics have gone haywire over the weekend. Starts by warning of tyre pressure malfunction followed by immobaliser malfunction and occasionally the whole dash light system lights up like Blackpool in October. Also speedo and rev counter will temporarily drop to zero. Garage are having difficulty isolating the problem. Turn off the ignition and lock car it will reset. Then problem will start again in an indeterminate time. Ford dealer has the car at moment to try and isolate the issue. Anybody suffered similar problem?

Sounds a strange one. It'll be interesting to hear what they find.. Could be something simple like a bad earth somewhere ?

Yep, almost certainly a loose earth connection on the battery or where the earth lead connects to the chassis.

Thanks for comments. Hope it is that straightforward. Will let you know what happens.

Garage have had a good look at car checked wiring disconnected various components and traced the issue as far as the CAN system but unable to locate. Reset system and could not get it to default again. I have car back and done about 1000 miles so far not happened again. Fingers crossed it was a loose connection somewhere that was fixed in the process.
