Never gotten any code messages. Only a display that says to check the engine electronics. Occasionally if I drive it real hard the gp light will come on for a few minutes then go off.
Battery checked out ok last month when we replaced the K40.Don't know how old it is.
Car did the same thing last winter and I hoped that a new K40 would fix it.
As long as I plug it in it will start right up,but it is aggravating and I'm afraid it will get worse.
