Had to take the H3 to the dealer yesterday after a slight smell of coolant inside the cabin turned into a mist of yuck through the vents. The mornings here have been cool enough for a little heat, so I turned fan to 1, and within 10-15 seconds the entire cabin, windshield, and front windows were fogged. Service manager called today to let me know that the entire back of the heater core was cracked. At 4400 miles, this is their first chance to provide great customer service. I am kinda concerned about the huge puddle it left under my mats. Cashmere carpeting does not look good with that coolant color.
Has anyone else had this issue? Service guy said it was the first that he had seen on the H3.
