There is a ticking noise coming from under the hood of the car. What could it be?

is it very loud or just barely noticeable? could be lifters.

Could be low oil levels causing the valves to tick.

Or could be because you are using the wrong type of fuel , you should use higher Octane fuels

Could it not be all these plus. As in bent valve in engine? I would suggest going to mechanic asap before anymore harm is done to the vehicle.

I have the same problem did you find out what it was

I just bought the rio ex 1.4 hatch and have ticking noise under hood until engine heats up. It does say in manual that ticking noise is normal when you start engine, something to do with abs . but i am taking it back to garage to inspect .

Still ticks every now and then fine atm like it fixed itself I have noticed it is worse when I put more oil in ect so maybe thats what it is got me stumped never buying a little car again as it seems a really common problem

May only be this as posted alreadyIt appears to be a generic thing with this Vehicle. I also have a Rio SLS GDI 2012 model. Initially there was a ticking noise or sounding more like some Cricket under the Bonnet. Same thing; Asked them and was explained that it was the GDI fuel injection system. This sound was only there in part in the mornings and would eventually go away. Now it is there all the time. Guees that is just the way the Vehicle is. As long as it is not detrimental to the vehicle all is fine with me. How ever" I will enquire further in my next Service Schedule. >>>
