1 Radiator problem

Failure Date: 12/02/2019

I was driving to work on a busy highway when I noticed the temperature gauge rise quickly past it's normal range. I quickly got off the road and shut off the engine. I had the car towed to the shop and the mechanic found that there was no fluid in the radiator. He determined that there was a small crack. He informed me that this is an issue with 2007 Civics. He told me I could put another motor in it or buy another car. The car has been well maintained and I had every intention to keep it for several more years. I am very disappointed that Honda did not inform me of the defects in the engine.

2 Radiator problem

Failure Date: 08/17/2019

I was driving my 2007 Honda Civic on 8/17/19 when I noticed my vehicle temperature gauge increasing at a fast rate. I immediately pulled over and found out that my car didn't have any coolant. Thinking that this was the problem, coolant was filled in the radiator and I was able to drive the car home. However, less than a week later, the car began to overheat once again. After inspection, my car was out of coolant again. I took my car to ed napleton Honda in oak lawn on 8/26/19 and was told that the engine cylinder block was cracked and was causing a leak of the coolant which causes overheating in vehicles. Although this is a known defect in Honda Civic models 2006-2009, I was told that Honda issued two warranty extensions for up to 10 years and that my car was two years outside of the warranty. Because I'm the original and sole owner of the vehicle with great maintenance history, the dealership's service manager submitted a goodwill request to Honda corporate asking for the cost of repair to be covered. However, the request was denied by the regional Honda district parts and service manager. I escalated the situation to Honda corporate and found out from a customer service specialist that Honda did not send the letter informing me of the defect and warranty extension to my correct address. Furthermore, it was not an address that I had ever provided to Honda. After escalating my issue to the regional case manager, I was still refused any assistance. There are over 300 complaints about cracked engine blocks in 06-09 Honda Civics on the car complaints website alone. Many owners state that their vehicles began experiencing problems shortly after the warranty expiration. This questions Honda's knowledge of the longevity of the engine block and all parts involved. I appeal to NHTSA to investigate this ongoing matter and hold Honda accountable by enforcing a recall.

3 Radiator problem

Engine block has developed a crack that is leaking radiator coolant and causing the engine to overheat. This could result in the engine being damaged and vehicle shutting down while driving.

Cracked engine fluid came out causes damaged to other parts and over heat due to engine crack damaged water pumps radiator.

5 Radiator problem

Failure Date: 01/05/2018

Engine block warranty extension. I recently noticed that my car started to overheat, and that the coolant was always gone with no leaks. So I began the process of changing the thermostat, it ended up not being the thermostat. I continued the process of trying to track the problem. After a radiator, hoses water pump and all other things a car would need to function involving coolant was replaced I was left clueless and stumped. Therefore, I went to Honda forums and google, and that is when I found out about the warranty extension for Civics because they were developing a problem with cracked blocks. This explained everything, went to forums and a lot of people were having the same problem. Honda customer service was the worst and basically told most people that it was out of warranty and most of the people did not even receive a notice such as myself. The engine blocks area completely weak and needs to be fixed. This issue usually occurs around 80,000-110,000 miles. This warranty needs to be extended especially for people who bought the car used as myself, I received a notice for the airbags and did not receive a notice about the motors, so I believe it is not fair and that Honda really is stealing money from people.

6 Radiator problem

Failure Date: 06/05/2017

After driving my car 3 miles, I noticed steam coming from the engine. I parked the car and it had a smell of radiator fluid. After letting it cool, I looked inside the radiator and noticed there was no fluid left. We filled it up and brought it to the local repair shop. They said the engine block had cracked. Honda had issued an extended warranty for 10 years for the original sell date for cars with this particular problem. Unfortunately, my car is out of the 10 year warranty by 6 months. Honda will not help out in any way since I am out of the warranty period even though it's a known fault.

7 Radiator problem

Failure Date: 03/05/2016

My Honda Civic has completely overheated three times to the point of needing to replace the head gasket, water pump, radiator and coils. Once was in 2014, again in 2018 and now in 2020. It is now discovered the cause of all these over heating problems over the years was due to a cracked engine block which there was a 10 year extended warranty for this issue. I took my Civic into brandon Honda in florida on March 5th, 2016 and nothing was said or done relating to the issue of the cracked engine block which Honda had been fully aware of since at least 2014 where it was stated on consumer reports. The vehicle was in motion twice, once on a highway and it was due to the engine over heating every time; both situations put myself and vehicle in danger. I maintained my radiator as well as water pump and have had them replaced each time so clearly the underlying problem was the crack in the engine block.

Engine temperature guage started registering hot, radiator fluid was leaking out of engine, vehical was towed to bob sumeral tire,they looked at the car and advised me that the engine block was cracked.

9 Radiator problem

Failure Date: 12/18/2013

Car engine was running "rough" upon start for 2 days; worked out after driving 1-2 miles. Drove 15 miles and stopped to fill up with gas. Less than 1/4 mile after fill up,engine light came on. Had car towed to mechanic who had performed last oil change and major service (a month or so previously). Mechanic identified problem with #4 cylinder. Mechanic swapped spark plug in #4 cylinder with spark plug in #2 cylinder. Less than a week later engine light on again. Problem again with #4 cylinder. Replaced all spark plugs and engine air filter. One week later, heater stopped working. Next day, radiator (coolant) gauge on dash moved up past mid-point and hits 3/4 point. I stopped driving and had a friend bring coolant which was 1 gal low! (note: mechanic checked and found coolant level full when car was in for engine light problem less than a 10 days previously. I drive less than 15 miles per day. . . All low speed. I park off street and have car in one spot for 9 hours during work and never saw any fluid on parking spot. ) added coolant. 1 week later (coolant) gauge on dash moved up past mid-point and hit 3/4 point (after driving 5 miles at 45 m. P. H. Or less). Stopped driving. Checked coolant level which was fine (full). That night got letter in mail from Honda saying that 2006 - 2009 Civics may have cracked engine blocks. All "symptoms" described in Honda letter matched what I had been experiencing (unexplained/undetected coolant loss, overheating, engine problem as evidenced by dash indicator). Brought car to Honda dealer. They said no problem with engine block. I asked them to check radiator thermostat. They said no problem. They could not explain why I lost coolant. I am in process of getting second opinion because I do not believe that Honda is committed to fixing the problem (which obviously is a manufacturing defect).

10 Radiator problem

Failure Date: 11/04/2013

On November 4, 2013, I was driving thru at a mcdonald's when my engine steamed over, spilling antifreeze. I towed it to my brother's house as I was at least 100 miles from home. He applied a coolant pressure tester to the radiator and found a leak coming from the engine block. I had the engine replaced by him. I filed a claim with Honda under the recall to get my money back. Honda refused to pay the claim, even though recall 10-048 from Honda offers to repay customers for their expense by warranty up to 8 years and unlimited mileage. At the time the car was 7 years, 1 month old. I claimed this to Honda in August 2015, was denied in September, 2015, reason given was that my brother is not qualified as a professional mechanic to diagnose, but a coolant leak is easy to find with a pressure tester and my brother has worked on engines for years. I am out $1700 from this repair.

11 Radiator problem

Failure Date: 10/17/2013

Brought vehicle in to dealership due to leaking (green and brown fluids). Was told that engine block was cracked and needed to be replaced, along with the radiator. Was told that tires were showing wear that should probably be replaced soon and was told this was possibly due to the control arm issue in 2007 Honda cars causing uneven wear on tires. Paid for new tires and labor for install. Paid for new radiator and labor for install. Was not charged for control arm part. Was not charged for parts/labor on cracked engine block. On 11/11/2013, brought vehicle back to dealership due to continued leaking. Was told that clamp on the radiator had not been tightened properly.

12 Radiator problem

Failure Date: 06/14/2010

I was driving locally yesterday, and my car overheated. I pulled over and let the engine cool down, then checked the coolant in the radiator. It was empty, as was the reserve tank. After letting the car completely cool, I drove it to the local gas station and purchased some engine coolant. I filled up the radiator and the reserve tank, and drove home. I had an appointment at a dealer for today already, so I brought this up to them. They said it was a cracked engine block. This car is a 2007 Honda Civic lx, with ~65k miles on it. It's not even 4 years old yet. I'm waiting on the dealer to find out how much this will cost me.
