   cracked engine block leaking coolant. Honda says it's not covered after the extended warranty expired. The issue starts happening in many vehicles after 100K miles and my car started seeing the issue at 135K miles . Dealer will not help, Honda of America won't help. this needs to turn into a recall please. Honda must reimburse or have the crack fixed.

   The car developed a crack in the engine block resulting in coolant leaks. This is unsafe and produces a toxic smell. The car is only at 119,000 miles and Honda will not cover it because it is 10 years past the warranty date. This warranty needs to be extended further. 119,000 miles is not a good quality Honda product.
