I have owned my TCH for approximately 3 months. Every single time the vehicle has sat unused for more than 3 days, I end up with a dead starting battery. It starts immediately when jumped, but this is becoming more than a bit annoying. The dealer at first insisted that the $350 starting battery was defective and has replaced it 3 times. They are now convinced that something is intermittently draining the battery, but after having the car for a week on one occasion and almost a week currently, they have no clue what is going on. I had thought it was probably the smart keys “communicating” but on the most recent dead battery occasion both keys were 1300 miles from the car. I am beyond careful to be certain that everything is off and lock the car every time it is left. Any ideas or similar experiences??
