Just had this problem pop up.

This evening i went to active the cruise at about 80kph, it said it was on but it wasn't - the car just slowed down.

Tried it a few times at different speeds, same thing - cruise says it's activated but it is not holding any speed.

No error messages, no warning lights.

I have recently had a few things replaced on the car including front left seat belt sensor (which was stopping the front left airbag sensor from activating).

I've also had a new right rear light assembly fitted along with several light bulbs.

No other warnings or alerts, car has had a flawless service history.

Any ideas?
