Engine block is cracked . . Leaking coolant.

Failure Date: 03/03/2018

On 3/3/18, at 92000 miles, the engine block cracked, causing coolant to leak. Apparently this is a known issue for many 2006 to 2009 Honda Civics, as Honda extended the warranty for this to 10 years (unlimited miles) from the original purchase date. Unfortunately, it seems that this issue typically doesn't occur until after 90,000+ miles, and I don't drive the car that many miles each year to reach the "danger zone" for this issue within the 10 year extended warranty period.

Last week I was changing the transmission fluid on my Honda Civic and noticed coolant leaking and turned out that my engine block is cracked and leaking coolant. After doing some research, I found out a lot of other people are having the same issue and Honda has a technical service bulletin 10-048. I never received a letter about this. I called Honda and turns out I was too late to be eligible for this service bulletin. This is a manufacturing error and Honda should be responsible for the replacement of the corrected part. I can not afford to pay for this repair out of my pocket and even if I can I would have to take the cheapest rout and buy a second hand engine and I will have the same problem again. If can get any help form you with this it will be greatly appreciate it. I am not the only one with this situation. This is a safety concern as well because this is my daily driver and I also use it for the the ride sharing platform uber. The engine may blow up while I'm driving so this is not safe and Honda should take responsibility before anything happens. Thank you.

Engine block developed cracks resulting in coolant leak and overheating. 130000 original miles, I'm the original owner. This vehicle has always been well maintained. Honda is aware of the design problem but is not willing to do a recall.

Failure Date: 09/29/2017

After taking the car our 2006 Honda Civic model to Honda dealer service for TSB 10-048 for (Honda Civic 2006-2009 year model) due to engine coolant leak which caused the engine to overheats while he was driving from his work, it was confirmed that it was a valid engine defect,by Honda technician - a cracked on engine block was the caused of the problem. However, since we both the car originally from the same Honda dealer place with the delivery date of October 2005. They consider the car as 11 years old and outside their 10 years warranty and the only warranty the american Honda corp will be 50 percent of the parts and labor cost for removing and replacing an engine. My point is, its because my car model between was purchased oct 2005 and not 2006 they will not provide a full warranty coverage the manufacture defect from the company? our entire family and household owns 5 Honda cars, 3 Civics, 1 accord and 1 crv with the trust on the product they have in the past. How can't they maintain a good quality product on the line. This is the 2nd Civic in our household with the same problem, our daughter's 2008 Honda Civic had the the same issue and they replaced the engine at no cost last summer 2016. Why can't they fully cover this one, with the same engine defect just because it was purchased 3 months shy from the delivery date before 2006. Honda would like us to pay $2000 for them to perform unschedule repair due to the defective engine they install on the Civic's car between (2006-2009). How many consumers who purchased those Civic's that are not aware of the technical service bulletin and unaware of the TSB but instead decided to shoulder the entire cost have an operational car in the household, because there is no recall considered to send to the american people? hope this issue gets resolve.

Engine overheated when driving causing danger to get to side of road, when checked coolant near empty. No leaking of coolant was noted. Dealer tested engine and block cracked at 93k. Dealer states this is a known defect by Honda on this make and year but will not cover.

Failure Date: 08/11/2017

After diving my 2006 Honda Civic about 5 miles, I could smell it burning and seen smoke coming from under the hood. Notice the temperature gauge was high and the car wouldn't start. . . Had the car towed to Honda where I was told the warrant had expired. . . I have a 2006 Honda Civic, it developed a cracked engine at 120k miles and coolant leaked. Its a known issue with Honda Civic with a weak point in their new aluminum engine with a warranty issued number 10-048. Initially the warranty was issued for 8 years and then increased to 10 years. How ever my Honda is 11 years old and in spite of low mileage Honda refuses to do anything. Shame on Honda for providing a defective product and not fixing it.

Failure Date: 07/13/2017

I took my well maintained Honda Civic into a local mechanic to repair my air conditioning and after spending $250 was informed it wasn't a problem with the ac, but that my engine block is actually cracked and is leaking coolant. My 2006 Honda has 142,000 miles and has been running very well up to this point. Apparently if my engine block would have cracked 10 months ago it would have been under warranty. But because it's a 2006 and the warranty only lasts for 10 years I am out of luck. My car that was worth $5000 to $6000 a week ago is now valued at $0. I feel like someone just stole my car or at least wrecked it. I have checked with my Honda dealer and Honda corp. Neither are willing to help with a new engine repair, I realize that my car is 11 years old, but when I purchased this Honda I figured it would go at least 250,000 miles. That is why I bought it. I hesitate repairing the car, which will run about $1800 because the new engine block could also crack! Honda knows there is an engine block problem, but they are unwilling to resolve it.

Failure Date: 07/09/2017

TSB 10-048. Lower engine block cracked and coolant leaked causing engine to overheat and fail. This is a manufacturing defect described in service bulletin 10-048 as a result of how the block was cast. The service bulletin extends warranty of the engine block to 10 years from the purchase date but my 2006 Civic falls outside of the warranty range right now and american Honda refused to cover the replacement cost. The engine replacement cost is now worth more than the value of the car. The issue happened just getting off the highway. The heat gauge shot all the way up and the engine seized with white smoke coming out. There were no indicators on the dash prior to this so it was not possible for me to notice coolant leaking.

I have a 2006 Honda Civic, it developed a cracked engine at 110k miles and coolant leaked. Its a known issue with Honda Civic with a weak point in their new aluminium engine with a warranty issued number 10-048. Initially the warranty was issued for 8 years and then increased to 10 years. How ever my Honda is 11 years old and inspite of low mileage Honda refuses to do anything. Shame on Honda for providing a defective product and not fixing it.

Noticed a engine block coolant leak in the front. There is a TSB 10-048 but only for 10yrs from 2006. Clearly this is known problem. What can I do to get the engine replace from Honda.

car   Coolant Leaking problem 13
Failure Date: 03/27/2017

My vehicle started leaking coolant due to a crack in the engine block. Honda has an extended warranty for this exact issue, and the letter acknowledges the existence of a defect in the vehicle's engine causing this issue. The warranty for this issue was extended to ten years, but my vehicle is currently a little over eleven years since purchase, and Honda declined any assistance. There are numerous other accounts of the engine cracking in this manner right after the extended warranty expired. Further, despite being applicable to all 2006-2008 models and certain 2009 models, the engine replacement is only offered after the crack/overheating event occurs, and owners have no ability to replace the defective engine under this warranty without experiencing a prior failure. This defect should be addressed for owners in what appears to be a common situation beyond the ten-year warranty extension.

Car overheated while on highway. Quick check found coolant had dropped. Added coolant, leak unknown. Took to Honda, they said leak from engine block had a letter from Honda with this issue for 06-09 engines it could happen. Instead of recall, they extended warranty to 10 years. Mine expired last 07-2016. Found others who had issue around 90k miles. Mine is at 89,500 miles. Many other may face same issue, left facing an expensive repair instead of recall. Honda will not budge any replacement due to known issue or aid in a reduced cost.

Was driving my 2006 Honda Civic home from school and suddenly noticed coolant leak/smoke. Took to Honda dealer who told me there was recall for cracked engine block but has since expired and now want $4500 to repair - more than the value of the car! I can't believe there's ever an expiration on a recall. Honda really wants unsuspecting people out driving with a known problem? there was no way for me to have known this potential problem since when I checked my VIN #, no open recalls showed up (I guess since it was already expired when I purchased it - July 2016 from used car lot). Pretty disappointing that a dealership could sell me a car with a known recall. Please help me. I'm just 17 year old student/athlete, hard- working and bought the car with my own $ and now feel ripped off and helpless. I've taken excellent care and pride in my car so this issue is devastating to me.

Failure Date: 02/02/2017

Engine block cracked and is leaking coolant, requiring replacement of the whole engine. This is a known issue covered in Honda technical service bulletin 10-048, but that only extended the warranty to 10 years. My car was originally sold in July 2006, so this happened about 7 months past that 10-year cutoff. I've been quoted $5800 for a new engine, which is more than the car's value. There are many other owners of 2006 models in the same situation already, and there will be even more as each subsequent model year up to 2009 hits the 10-year mark. Luckily I caught this problem before it became a major hazard. First the car's heater quit blowing warm air, then a few days later I noticed coolant leaking from underneath any time I parked. I took it to a mechanic who found the crack in the engine block. If I hadn't noticed the leak and the coolant had been completely depleted, the engine could have overheated and possibly failed altogether while driving.

Failure Date: 12/16/2016

The car has a cracked engine block and is leaking coolant. Per research Honda is aware that this is an issue for 2006 - 2009 Honda Civics and extended the warranty for 10 years on the motor. The original owner purchased the car in may 2006 and my daughter bought it from a dealership in December 2013. We were not made aware of an extended warranty on the motor or that this could be an issue. Honda was contacted and they are refusing to assist my daughter with replacement of a motor that will now cost her $5000 on a car she still owes on.

Failure Date: 12/09/2016

Takata recall. I was at a stop light when I noticed that my car was running extremely hot. Smoke was coming out from under the hood, and it had run out of coolant. We then found out that it was leaking coolant from a crack in the engine block which is a known issue with Honda Civics from 2006-2009. When we contacted Honda they told me that the recall had been expired since may of 2016 and there is nothing they can do to help me. This crack in my block is due to Honda's negligence in manufacturing process of their engine blocks, yet they refuse to take responsibility. The car has had no other issues and has been properly maintained.

Failure Date: 11/16/2016

The vehicle is has a defect in the engine where the lower engine block corrodes, leaks coolant, and then as a result overheats. This defect has been admitted to by Honda and they have issued TSB 08-044. This happened to me and as a result I was stranded without a working vehicle on the side of the road. I contacted Honda regarding this and was told my car is 2. 5 months outside the warranty. I was offered an insignificant amount of assistance with the cost of the repair. I understand the warranty is expired, but I firmly believe that Honda should take responsibility for their mistakes, which they have refused to do.

While the vehicle was at the dealer for an oil change, the technician attempted to drive the vehicle into the garage, but the engine failed to start without warning. The technician diagnosed that the engine coolant leaked onto the engine and caused it to shut down. The technician stated that the failure was not included in a recall. The contact found a TSB and made the manufacturer aware of the failure and a warranty extension that was noted on the TSB. The manufacturer stated that the extended warranty was expired. The vehicle was not repaired. The failure mileage was approximately 210,000. The VIN was not provided.

Bought a 2006 Honda Civic with 54,000 miles in August of 2016. On a 6 hr trip to omaha nebraska the engine began to overheat. Pulled into a gas station and discovered that the coolant was nearly empty. When the car was taken to a Honda dealer I was informed that the engine block was cracked and leaking coolant. It would have been replaced by Honda but the extended 10 year warranty had expired by 7 months. Currently on the hook for $5200 because of Honda's known defective part.

While doing general maintenance on my 2006 Honda Civic (stationary) I noticed it was leaking coolant. After working on the car to find the leak and doing research online I found out that there is a known manufacture defect for 2006-2009 Honda Civics that causes a failure and crack in the engine block. There is a 10 year warranty extension, which I am beyond by 5 months so Honda has refused to fix the vehicle under warranty. As an owner of two Honda vehicles I am severely disappointed, especially since I was never notified of this by mail or otherwise by Honda. I have received information from them regarding other issues on my 2011 accord, but never about the 2006 Civic. If I had I may have been able to identify this problem within the warranty period as a small leak before it began dumping/pouring coolant. Luckily, this never led to severe engine damage due to overheating while driving, which could have caused serious risk of accident and injury. In addition, Honda was exceptionally rude and unhelpful on the phone. After days of going back and forth with them they finally gave me a claim number for the issue. Once denying it they told me that I could call their claims department, which I already believed I was speaking to. To my surprise the number they game me was for the court system that had ruled on this case for Honda. So, after wasting my time with them they felt it was appropriate to play what amounted to a practical joke on me. The worst joke of all is that they have failed me as a customer in all possible ways. I fully believe that this issue should be made a complete recall, as it is a known manufacturer defect and no fault of any customer who owns one of these vehicles.

Failure Date: 08/12/2016

On the date of August 12, 2016 (Friday) at or around 5:40 pm est. The vehicle broke down in motion and was unable to drive due to something involving the engine. The vehicle was on a city street. It had to be pushed off the roadway. Noticed coolant leaking on the ground from the engine. The vehicle was towed by aaa to our local repair facility. On Monday morning August 15, 2016 the vehicle was diagnosed as having a cracked engine block. At this point I had information on Honda's engine block problems. 2006 Honda Civic ¿engine block crack¿ technical service bulletin 10-048: the problem: the engine block may leak coolant, resulting in engine overheating. Corrective action: dealers will replace the engine block free of charge. Warranty info: repairs will be done under an extended warranty (10 years from the original date of purchase, no mileage limits). My 2006 Honda Civic was purchased August 14, 2006. The engine failure happened during the warrant period. My local Honda dealership and american Honda refuses to repair my vehicle at 100% they offered split cost for the engine block of 10% for me to pay. They also said the the gasket cylinder head was damaged due to over heating because of the cracked engine block. They had me pay 50% cost of the repair. They also had me pay 10% for replacement of coils. All this damage was due to the faulty engine block. TSB states replace the coils and check for head gasket damage. If damage is found go to step ?? I conclude it means replace the gasket cylinder head. Honda clearly knows of this issue and has not issued any recalls. Vehicles dying on the highways and byways in traffic and motion should be a safety concern. My vehicle was in warranty I should not be paying anything. I did not even ask for towing or alternate transportation nor was any offered. TSB 10_048.
