I have engine management light on dash come on and has done for last couple of weeks at same time as message on dash saying stop/start system fault. The car starts no problem and is running absolutely fine but message appears every day as well as warning light so any ideas please before I take the plunge and go to Nissan. I have a Quashqai 2017

I would have the battery condition checked.

Although it may start every time, the condition may be slight off par and this could affect the stop/start system and also it may need the charging system voltage to be reset (if required) as this can flag the light
