    Unhappy Coil Pack rubber melted into the spark plugs (Spark Plug Wires Melted)

    Hello I'm new to this forum. I'm also one of the few drivers that has managed to rack up 100K on her Volt. I just went to the dealer on President's day and I was told they had never seen anything like this before and that it is something that could potentially be seen with drivers as they increased their mileage on their volt. Has anybody with a high mileage in their volt been told by a dealer or mechanic that their spark plug wires have melted? The exact words from the dealer were, " your coil pack rubber has melted into the spark plug." I never received any notifications from vehicle that the car was over heating, so I had no way of knowing this. Anybody else with a similar experience? Thanks.

    That's a new one - pretty sure it hasn't come up here before.

    Why did you take the car to the dealer? What I am getting at, is it something they noticed during a routine inspection, or was the car not running right?

    Something would have to be terribly wrong with the car for it to melt the plug wires. Either the head got physically hot from a problem like leaky head gasket, but you would see a temp warning in the car for this. Maybe plug wire got super hot from drawing too much current? Improper spark plug gap or something? Photos would be helpful.

    100k is not really high miles, and I don't think this is a normal problem, seems like a specific issue from something else being wrong.

    Something is really wrong there! Silicone rubber is good up to a bit over 500 f, if my memory is working.

    Yes, some pictures of the melted pieces would be of interest.

    I'd say you were targeted for unnecessary repairs ... ask Elemental for more details if your not understanding this post

    How often does the engine run in the 100K volt? Perhaps it occurred previously and was not detected due to not running the engine?

    A very rare occurrence on any vehicle, especially a Volt. More details please.

    Considering the OP had the foresight to ask the GM service dept. to give her the melted wires following replacement...

    Yes, if I was told the wires were melted I'd want to see them, not to prove them a liar, but just to see them. Of course if they can't produce them...
