What owners say about the engine

Verbatim from NHTSA complaints, newest first
“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.”

“- What component or system failed or malfunctioned, and is it available for inspection upon request? My 2006 Honda Civic engine overheated. Upon diagnosis it was found that radiator coolant had leaked out due to cracks in the engine block (short block). Engine malfunction. - How was your safety or the safety of others put at risk? My teenage son drives this car and initially he did not notice coolant leak. Engine can stop working while driving on a freeway (seized engine) which is a very serious safety risk. - Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, local Honda dealer confirmed the problem and pointed me to a service bulletin 10-048 from American Honda [XXX] ) that noted this exact manufacturing defect. American Honda had provided extended warranty to allay customer fears at the time but without a recall. - Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by a Honda dealer, Tracy Honda at California. It was also inspected by another local auto shop and had the same finding. I am attaching those documents. - Were there any warning…”

“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.”

“Engine overheats due to a crack in the engine block causing the coolant to leak.Overheated engine smokes and has the potential for fire. I did my research and spoke to handful of certified mechanics, the solution is as I understand is to replace the engine. there was a recall notice sent September 2014 to address this issue which I did not receive nor I had a problem at the time of notice. Could someone please look into this for us, it would greatly help me and my family to be safe on the road while driving this vehicle. Thank you,”
