I own a 2005 Accord Hybrid V6 that won't start in cold weather. The hybrid battery pack is only 4 years old and so is the front battery. In previous winters, the car would start like an ordinary Hybrid auto and when the weather was cold it would start like a regular auto (with the regular starter motor). This past winter when the weather got colder (under 30 degrees) I turn the key and nothing happens...all the dash lights come on but nothing else. Anyone have any ideas?
