Owner reports
Selected complaints filed with NHTSA by 2007 Honda Civic owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2007 Honda Civic. The contact stated while driving at 5MPH and parking in front of her residence, she noticed that smoke was coming out of the hood of the vehicle and the vehicle was overheating. There were no warning lights illuminated. The contact turned off the vehicle. Upon opening the hood of the vehicle, the contact noticed that the smoke was originating from the engine compartment. There were no injuries sustained. The vehicle was towed to an independent mechanic where it was diagnosed that the engine block was cracked. The independent mechanic informed the contact that the failure was associated with Honda Technical Service Bulletin Number: 10-048. The manufacturer was notified of the failure and advised the contact to take the vehicle to the dealer for diagnostic test. …
Engine Block cracked and leaked all coolant abruptly. Car has ~47k miles on it. Honda addressed this issue by extending the warranty discreetly to 10 years with unlimited mileage. This warranty extension was clearly designed to target owners who had more drive time than others. The bulletin posted here -> https://static.oemdtc.com/TSB/A10-048.pdf states it was posted in January of 2015. That means my well-cared-for 2007 Civic had only two years to encounter the issue, or else the replacement would not be honored. I purchased the car in 2019 used, and did not realize the engine was to be faulty. Not even 50k miles into the car's life the engine block failed, almost catastrophically. This leak could have lead to a fire hazard had I not been paying attention to the car's temperature. …
My Civic was diagnosed with a cracked engine block, an issue known by Honda to be problematic, as they issued an extended warranty on the engines that ended in 2018. However, the extension has expired despite the fact that many Honda owners continue to experience this problem (see https://www.8thcivic.com/threads/documenting-cracked-engine-block-for-those-out-of-the-warranty-coverage.609546/page-7). This issue should be considered more serious than just an extended warranty, as an engine leaking coolant could easily overheat and cause serious problems on a road trip, especially in the part of the country I live in (Montana), where summers are hot and dry and wildfires are easily ignited. …
Honda put out a warranty extension of ten years for certain Civic models for a known casting issue that led to a cracked engine block. Rather than issuing a recall, they settled some law suits and did a warranty extension. I recently purchased a 2007 Civic from a relative who was unaware of the warranty extension. The car is five years passed the warranty expiration and Honda will do nothing to assist with this very well known issue! I find it completely unfair and unprofessional of Honda to offer no assistance for an issue they admitted full fault to! I now have a cracked engine block and no help from the once reliable auto dealer. I would be more understanding if this wasn't an issue that causes catastrophic failure, but this is unacceptable. I firmly believe that Honda should issue a recall for the known issues and resolve them in a responsible manner.
As I was driving down the road my car began to smoke and I noticed it was overheating at a stop light. I managed to be able to pull off of the road before the smoke got any worse. It may have had the potential to cause a fire. I was able to fill it with enough fluid to manage to take the car to my house so we could take a closer look at the issue. We found that there was coolant leaking out of the engine block and that there is a known service bulletin for the issue that has been released by Honda. It was apparently only applicable to cars that were less than 10 years old to cover under warranty. Given that my car only has 81,000 miles on it I would expect it would be covered under this warranty but they are telling me they will not cover any of the costs at all.
Cracked engine block to the front, lower passenger sideof the engine block behind of the catalytic converter. Issue unknowingly began when commuting on the freeway until car was left parked for an hour. Coolant had puddled under the car in that time and upon inspection noted dried blue coolant sprayed all across the under side of the car originating from the cracked area indicating I was still driving when the leak started without any warnings. Given how much coolant leaked over that hour, this could cause rapid engine overheat while driving if the leak remains unknown. After some research, Honda knew about this manufacturing defect for a number of years and issued an extended warranty but those have all since expired, while engines are continuing to crack and fail.
In January of 2020 my engine started to overheat, It was lack of coolant of course, so after that incident I have to check every few days and I have to add more coolant into the vehicle, I have had it checked by three different mechanics and they said there is no leaks, but I keep having to add coolant to the reservoir, and when I don't check after a week the radiator is empty. I have heard about cracked engine blocks in my model, yet Hondas website says my vehicle has no recalls. This website says I have NINE that have NOT been repaired. I have tried calling Honda and they told me I had to pay for any engine issues since I bought the vehicle outside of the warranty time limit. I really like the car it's a shame.
The engine block cracked which resulted in the coolant leaking out of the vehicle. This is a safety issue to myself and others on the road as the engine could seize. The engine and coolant system were inspected and the problem has been confirmed by an independent mechanic. The first symptoms of an issue appeared on 09/12/2021 after I exited a highway and stopped at a traffic light. White smoke was coming from the hood and I could smell burning coolant. Honda is aware of a manufacturing defect of these engine blocks and issued an extended warranty for 10 years past original purchase date. This is a dangerous safety issue and Honda should be recalling all of these vehicles regardless of age.
There is a crack in the block that has nothing to do with external damage or lack of maintenance. It is available for inspection upon request. The engine lost a significant amount of coolant and started to overheat on the highway. This could have resulted in engine seizure and a major accident. Our service person has confirmed that the block is cracked and that this has been identified by Honda as a known manufacturing defect. The vehicle has not been inspected by anyone else. The Honda dealer is not interested. The only warning was that the temperature gauge shot up.
I purchased this Honda Civic In February 2022. I immediately had to have a O2 Sensor replaced. A few days later the car starting running hot and all the antifreeze leaked out. I replaced the antifreeze and had several mechanics look at it. Now the Honda dealer tells me the Engine block is cracked. I know Honda settled a class action lawsuit for this exact reason (engine block cracked) in Honda Civics 2006-2009. Now I can't use my car. I need your assistance in getting my car repaired by Honda due to the nature of the history of the Engine Crack recalls. Thank you
