Hi, new owner here any advice gleefully accepted. I've just bought a Kadjar 2018 1.3 Dynamique petrol 60k miles. Second day, take it for a drive and near enough every operating fault message came up....check injection, check braking system, check hill start assist, check stop and start, low key battery. They are accompanied by the spanner warning symbol and I think there were more messages than that but I missed them. They came on after about 10 mins of driving and then went off. The car drives fine. Anyone got any ideas??? Thanks

With multiple faults like that, first stop for me would be to check the main battery in the car, to make sure its ok?

Afternoon 
I would agree with the last post it appears on other forums for numerous makes of vehicles if you get loads of faults as you describe it’s normally because the battery has suffered from low voltage at some time .
Loads of places will do free battery check
hope you get sorted
