1 Coolant Leaking problem

Failure Date: 11/18/2020

I just bought this car 7 month ago and replaced brakes, rotors, a tire, repaired a broken lugnut, and now the engine has overheated and blown and is evidently not covered under the previous warranty because it is past expiration (year and mileage). Putting a used engine into the vehicle is not going to solve the problem, and my dealership is not willing to put a new one in. When it began overheating, I had just pulled onto the highway (average speed of about 50) and noticed that my heat wasn't working (which was weird since I had replaced the thermostat already a few weeks prior) and then the car read as hot as possible. When I safely pulled over, there was smoke coming from under the hood and it was towed to a reliable mechanic who said it was the coolant leaking from the engine block, but was not part of the warranty anymore.

9 Coolant Leaking problem

Failure Date: 01/10/2019

Was the proud owner of a Honda Civic(2008) until recently. In January 2019, my Honda unexpectedly started overheating when I was waiting in line in mcdonalds. The overheating occured very fast and I I quickly pulled over and towed the vehicle to nearest Honda dealer (Honda of nanuet). I learned the next day that the car had suffered a engine coolant leak which had the made the vehicle inoperable. I found out that this was a manufacturing defect in the engine block (https://Honda. Oemdtc. Com/340/warranty-extension-engine-block-2006-2009-Honda-civic) which is a known defect on 2006-2009 Honda Civics. My cars situation is sad because it is over the 10 year warranty but has very low miles on it for a car of its age. . Read more...

10 Coolant Leaking problem

Failure Date: 11/14/2018

My engine block cracked while I was driving on the interstate, causing billows of steam to erupt from under my hood, partially blocking my vision while driving, the engine now leaks coolant and needs to be constantly refilled to keep the vehicle operable. Engine blocks don't just crack. Honda knows this is an issue with their vehicles, but they want me to pay more than $7000 to repair the engine! this is unacceptable. A cracked engine block does not fall under regular maintenance or wear and tear, not at any mileage, and especially not at 130,000. I want to reiterate that the engine block was the initial point of failure, as confirmed by both Honda and the dealership I took it to (hendrick Honda, charleston SC) and that the engine got so hot that it burned and melted the dipstick/top of the engine.

11 Coolant Leaking problem

Failure Date: 11/13/2018

Driving the car on the road it overheated and turned off, leaving me stranded in the middle of the road! took it to Honda dealership tech, to find out that the engine block cracks causing the engine to leak the coolant and overheating. This is a safety issue as the problem does not give any warning signs! also, it is a manufacturers defect. American Honda refuses to fix the problem. . .

12 Coolant Leaking problem

Tl the contact owns a 2008 Honda Civic. While operating the vehicle, the heater stopped working. The vehicle was taken to crown Honda (7671 us. 19 north, pinellas park, fa) where it was diagnosed that the vehicle was low on coolant. Coolant was added to the vehicle, but the failure continued. While changing the oil, the contact discovered that the engine oil was discolored due to coolant leaking into the engine. The vehicle was taken back to the dealer where it was diagnosed that the engine block was faulty and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 103,000.

13 Coolant Leaking problem

Failure Date: 10/04/2018

Catastrophic manufacturing engine block failure, as set forth in Honda TSB 10-048 & 08-044, which resulted in the sudden and immediate expulsion of all coolant from the vehicle rendering the vehicle inoperable. Please note that in its' technical service bulletins, Honda describes the manufacturing defect as "the engine (cylinder) block may leak coolant" . However, it is not a slow leak, because the engine coolant system is under pressure, while you are driving, when the engine block cracks all the coolant is sudden expelled from the system forcing a motorist to immediately pull over. Because you cannot keep driving with no coolant in the vehicle, it is an extremely dangerous manufacturing defect that forces a driver to take evasive action to safely stop the car. It's no different than if a car suddenly lost all its' oil or its' brakes because all these events force you to immediately and unexpectedly stop driving, which is dangerous to you, your passengers, and to other drivers on the road.

14 Coolant Leaking problem

Failure Date: 09/10/2018

This car started leaking coolant on the driveway. One day later my wife drives car and when she returns home steam is coming from engine and a lot more coolant is leaking on driveway. Towed it to the dealer. Turns out there is a factor defect causing engine block to crack prematurely. Luckily engine didn't overheat and lock-up while on the freeway. Scary that the symptoms and onset of crack were so sudden. Only started dripping on driveway one day previous to near overheat. Not sure if my wife or I would have been able to safely get the car to the side of the road if it overheated while driving on the freeway.

17 Coolant Leaking problem

Failure Date: 04/10/2018

My 2008 Honda Civic just started leaking coolant recently. It only had 70000 miles on it. . I was at a dealer 2 weeks prior to change brakes and I even had them do an inspection but they didn't find anything suspicious!! weird!! because later the coolant was leaking, my car started overheating, really bad. Turns out I was all out off antifreeze and coolant. The car started overheating. I took it to the Honda dealer on northern blvd, NY and they said the block engine is cracked and I asked about the 10 years extended warranty and the nasty sales guy I was talking to was very aggressive and asked to change different agent. . And I waited 15 minutes and another guy came and explained that the extended warranty on my car expired 4 weeks ago and I'm only allowed to have an engine replaced but I still have to pay for the labor 13 hours labor. . At total price of 1800$ . . . Since and, honestly, if I had been aware of this issue I would have looked at other vehicles. . . I'm sure there is a class action lawsuit about the engine block cracking in Honda Civic 2008. . This is crazy . . . . I thought Honda were supposed to be reliable!.

18 Coolant Leaking problem

Failure Date: 03/15/2018

My car is a 2008 Honda Civic lx model. On March, 15 2018 while I was driving on the highway, the car stopped running and smoke came out of the hood suddenly. No warning lights came on the dashboard till the last moment. Fortunately I managed to pull over the car to a safe place immediately beside the highway otherwise I would have been in a fatal situation. I had the car towed to my mechanic where they performed the diagnosis to find the root cause of the problem. They identified that there was crack in the engine block which has caused the coolant to leak from the engine and hence overheating of the engine has happened and made it to malfunction. They told me that the whole engine has to be replaced (used one) and few other parts as well (like spark plug etc. ) to make the car running again which would cost me around $2500. It was devastating to hear this. My mechanic told me that most of the 2006 to 2009 Civics had this engine crack issue and Honda is also aware of this. Despite this Honda has not called for the recall of such those engines and just did a warranty extension. TSB 10-048 was issued for this. But still a lot of 2006-2009 Honda Civics are facing this issue even at very low miles like mine. Mine has 166,000 miles. I checked with the service consultant if this would be covered under the extended warranty. She did a VIN inquiry and said that may car is still in warranty (the original purchase date of the car was 20-April- 2008 and this incident happened to me on -15 March-2018). This is a big blow to me. I raised this concern with Honda corporate and they filed a case. With number 07506763 with couple of days later (on 09/07/2017) the case manager probably will call me on Monday March 18, 2018.

19 Coolant Leaking problem

Failure Date: 02/19/2018

My 2008 Honda Civic si has been leaking coolant for the past couple weeks. It is currently at around 115,000 miles. I noticed all of the extended warranty information about the 06-09 Honda Civics and contacted both the dealership and corporate myself. They told me that because my model was not the base models but the si that it was a different engine and that they could not help me. However I am going to get the car back from my mechanic today who estimated the repairs would be $4500 to completely replace the engine. He also brought up this extended warranty issue and suggested I contact Honda again because the pressure fractures are in the exact same place as they are on the base model 06-09 engine blocks. From my knowledge and the mechanics the engines may not be the same but the block is made of the same material if not the exact same block. This is costing me my car as a whole and the $4800 loan I still owe on it. I am now out of a car unless I drive it and refill the coolant weekly until the engine completely seizes and stops working. This will put a huge affect on my job, financial situation, and my credit score at the age of 19. This is insane and should be Honda's job to take care of considering they are attempting to keep the entire issue for the other models on the lowest of lows they can to avoid paying for all the new engines. A company this large should not be able to put this many people out of vehicles and affect their daily lives because they thought this was a reliable and sensible brand.

20 Coolant Leaking problem

Failure Date: 11/11/2017

Engine developed a crack in the side and a coolant leak. This is a known defect and Honda has a warranty campaign but won't replace my engine due to a salvage title because of a theft recovery, not an engine rebuild or engine damage. The car only has 42000 miles. The replacement has been quoted at about $4400. The technical service bulletin is 10-048 and I think Honda is just avoiding responsibility to replace the engine due to the salvage title technicality. I will never buy another Honda and I own three now. I will tell everyone I know about the risks of poor quality engineering and unacceptable customer service that Honda has displayed in this circumstance. There needs to be a class action lawsuit.

Coolant leaks are coming from engine block. The leak causes coolant to drain away, leading to overheating or total engine failure. The vehicle will not accelerate, and shuts off in traffic.

25 Coolant Leaking problem

Failure Date: 02/05/2014

Car has been losing coolant for the last several months intermittently. Recently it was run down to almost nothing before I discovered it from a crack that cannot be found as of yet in the engine block area. Car started to overheat. Took to Honda dealer and they could not find the leak, though there is a voluntarily recall / TSB on the r18 engine cracking and leaving motorists stranded on the freeway. Will have to wait for car engine to completely fail before any real results from dealer/ Honda.

28 Coolant Leaking problem

Failure Date: 04/05/2008

The engine on my Honda overheated and got so hot it actually melted some of the components. Faced with a $4000 repair bill, I did some internet research and found that Honda had been aware of engine problems with 2006 through 2008 Civics. Honda had issued a bulletin to letting mechanics know there was a problem with leaking coolant. My husband was exiting a freeway when the car just shut down and started smoking. Had it happened sooner, there could have been an accident. I think Honda should have recalled these cars rather than wait until a breakdown happens and then do repairs. Even the service manager at Honda told us they had been doing of lot of these repairs lately. The potential for a breakdown in an unsafe area and cause an accident is great. Or at least make sure they get the information to their customers. They know where to find me to send my monthly bill, why not the warranty?.
