2007 Honda Civic ex sedan: upon a trip (60 miles) home from the cleveland airport 1-26-10, I smelled coolant burning and a sudden cloud of steam from under the hood. Upon further investigation of this incident, the determined cause was the engine block had cracked allowing coolant to be sprayed onto the manifold causing the burning smell and clouds of steam. While Honda cannot provide a reasoning behind this failure, it appears or would seem to be a casting issue for the 2006-07 models. The car is out of warranty by 35k miles at the time of failure and Honda declined all efforts to assist with this problem. I am hearing and seeing numerous issues exactly identical to mine well within the warranty period for others and Honda is claiming there is "no" problem with these engines. The car has been dealer maintained and has all highway miles due to my job. Not sure how many complaints it takes to issue a recall but there is definitely a problem with the 2007 Civic engine castings. This overheating could ultimately lead to a fire or serious injury should a driver not understand the indicant at hand. I do know there is a TSB regarding this problem #08-044.

Taking part to a professional welder to try to repair it. Otherwise, I'll have to spend $700 to $1000 to purchase a new one from Honda.

The check engine light came on. My husband took the car to a local automotive shop and was told that the O2 sensor had gone out. Upon further review, the mechanic found that there was a crack in the manifold and that I would cost about $1000 to repair. My husband paid $190 to have the O2 sensor replaces but was told that the O2 sensor may fail again due to the crack. The mechanic states that when he phoned a local Honda dealership to obtain a price quote on the parts the lady who answered the phone finished his sentence. The mechanic also said to me that this is a recurring problem that they have seen in Honda vehicles. This appears to be a defect in the vehicle as the same problem is happening at dealerships as well as other mechanic shops. This problem should be corrected at Honda's expense.
