Hi. I drive a 2013 chevy sonic 1.4. It has 60 000km on the clock and the coil pack had to be replaced twice now (R7000 per replacement; first time after 30 000km and second one now). It seems that moisture gets into the coil pack, where the spark plugs connect and it corrodes the metal parts inside which causes the car to sometimes jerk and have a loss of power. Has anyone else had the same problem? Is there a way to keep moisture away from this part? It’s really expensive to have to pay R7000 after every 30 000 travelled. Thanks in advance
 
That car probably has the EcoTec (Opel) engine. Get hold of Goldwagen, they may have a cheaper/better solution for you.

Let me guess, is that story of moisture getting into the spark plugs from the dealer/workshop? It sounds like BS to me. Where would the moisture be coming from?

The engine as it is was designed in a way that is supposed to withstand water going to where it's not supposed to.
 
Hi yes that was the story of the dealership. They showed me the coil pack and there is definitely corrosion/oxidization which implies that moisture had to get in there somehow. But my question is, is this a design flaw of chev? I’m thinking of selling the car before having to pay again
