2006 Honda Civic. Consumer states problems with water pump bolts when the mechanic started the vehicle, sparks were coming from the area of the water pump. When he checked the engine area, it was apparent that one of the three visible bolts holding the water pump in place had fallen off. The serpentine belt also needed to be replaced. The next day, the mechanic removed the faulty water pump, having determined it had been out of its normal shape. He further determined that the tensioner assembly holding the water pump in place was the incorrect part. It weighed 40 pounds, when the proper weight for that water pumps tensioner would have been about 16 pounds. When the mechanic ordered the replacement part, it was identical to the original part and informed the consumer it would only last 25,000-30,000 miles until the same problem occurs again. Updated 06/08/10.

The air conditioner on my 2006 Honda Civic failed. Since I have a 10-yr extended warranty, I had my Honda dealer diagnose the problem (cost $75). They told me that the ac condenser was damaged due to a rock/pebble impacting the condenser and that the warranty would not cover the problem. I had them replace the condenser (cost: $782). It turns out that there are hundreds of similar complaints about this defect for this Honda and others going back to 2003. There is absolutely no protection in the front grille that would prevent this from happening again. The design of this Honda welcomes debris to come through the grille! a simple $5 screen attached to the grille would have saved me $856. Something has to be done. I now have to look for my own custom grille to stop this from happening again. It's not if, it's when.

  • 49,000 miles
My car is 4 years old and approaching 50,000 miles. Yesterday after work I had made a stop on the way home and when I came out and started my car it was making a horrible racket. It was a loud rattling sound. I looked under the hood and saw the pulley on the water pump wobbling around like crazy. I had the car towed to the dealership I bought it at. Today they informed me they had to replace the water pump completely and charged me $500 for it. When looking online about the issue I found there had been a limited recall for the same make, model and year but my VIN didn't fall within the affected recall range. Is it just coincidence that I had the exact same issue as others with the same model and year or should my car have been included in that recall?

My 2006 Honda Civic hybrid engine blew up a week ago - Feb. 11 2008. Without indication, the engine stopped running. It is passed factory warranty which is 60K miles of 5 years. The car has 78K miles on it and it was well maintained. The original owner was a rental co and they maintained it well. It was bought by a broker who performed normal maintenance on it - oil change, air filter, brakes, transmission fluid and new battery before selling it to me. I performed regular maintenance as well. I took it to the nearest Honda dealer after it broke and they said they could not conclude what caused it, but the result was 4 broken spark plugs and a cracked no. 2 piston. Honda of America opened a case and closed it because 1. it was used, 2. expired warranty and 3. it was not maintained at a Honda dealership.

First my ac stopped working and then my temperature maxed out. I immediately stopped and had the car towed to a mechanic. It turns out that the engine block is cracked! yes, I have 132K. However, this is a known and documented design or manufacturing flaw. They need to address this and repair at no out of pocket cost for those that experience this problem! spoke to various people at american Honda motor co. And the response is mileage is too high so don't expect anything. If there did not seem to be such a large number of people experiencing the same problem, I would just consider myself unlucky. However, considering this is an issue that Honda has acknowledged and considering this is a fast growing list of people, it deserves investigation. Some customers, including some with high mileage, seem to have received substantial assistance. I was told that they were probably long term Honda customers and once that they would want to retain as customers. I guess Honda being the only two news cars I have bought does not count!

  • 66,000 miles
My Civic was a 2006 model with 88,000 miles. I was fortunate not to experience any mishaps while driving. My car was in the shop for normal maintenance at one of the local Firestone places, after they did the maintenance, they informed me that there was coolant all over the parts beneath the engine and they were sure that was coming from the engine block. They suggested that I take it to the dealer and have them check it out immediately. Took it to the dealer and sure enough, there was a crack in the engine block. The dealer replaced the engine block with no out-of-pocket cost. I was fortunate. However, I'm still not happy with the car because I had problems with the starter at 66,000 miles and then the suspension problems at 88,000 miles. Now, I'm experiencing some electrical problems with it. It has not been a good car for me.

  • 69,000 miles
2006 Honda Civic ex, 69000 miles. Driving to visit family on christmas day, my engine began smoking with no warning. The temp gauge never moved. I was able to safely exit the freeway and after letting the car cool, added over a gallon of coolant. I took the car to my regular mechanic, thinking it was just a hose or something, and he diagnosed it with a cracked engine block. He showed me tsb 08-044 and said the only way the engine block could have cracked is from a defect in the part. He suggested I take it to the dealership and inform Honda of the problem. The dealership confirmed the cracked engine block and offered me a 75/25% split, leaving me with a bill of $840. Honda needs to cover this repair for all owners at 100%, regardless of mileage. In my research, I have found that this known defect is becoming more widespread in 2006, 2007 and now even 2008 Honda Civics, as these newer cars begin to reach higher mileage. The defect is a result of faulty casting resulting in a porous engine block prone to cracking at normal operating temperatures, which Honda is trying to cover up. There needs to be a recall or at least owner notification so that people can have their car inspected for this problem before their warranty is up. I bought this car with a defective engine... I was just unlucky enough to find out about it after my warranty was up.

I was driving through rural Virginia when the temperature gauge quickly jumped to the hottest setting. I immediately pulled my car over. I was informed by a mechanic that my 2006 Civic with 87,000 miles has a cracked engine block. The car was towed to the dealer. I plan to have a new engine block installed.

  • 68,000 miles
Began smelling anti-freeze one week ago, took cr to shop 3 days later, told their is a crack in the engine block. 2006 Civic, under 4 years old, but 68K miles, so dealer says it is out of warranty. As they have seen similar problems, their district manager approved them covering 50 % of the estimated cost of $3100 to replace the engine / block. While I appreciate their generosity, I would expect them to cover it 100 %, as this is a known problem on the R18 engine used in the 2006 Civic. That I was unlucky enough to have made it passed 60K miles before the crack appeared seem ironic. I suggest that Honda make good on a 90 / 10 replacement program, 90 % of the cost covered by american Honda. If this was some other brand with a lesser reputation for quality and reliability, I would not be so surprised, but the Honda name leads me to expect better.

The contact owns a 2006 Honda Civic ex. The vehicle was taken to the dealer, and the tension bar was replaced. While driving 20 mph on a secondary road he heard a peculiar noise. The vehicle was taken to a local repair facility. The mechanic replaced the tension bar bolt and the serpentine belt at an expense of $543.36. The manufacturer was notified, and he was advised that they could not inspect the vehicle because he already had the vehicle repaired by an independent technician. The failure mileage was 110,000

2006 Civic cracked block issue. On Nov 10 I realized I had a coolant leak and took it into a local mechanic and he showed me I had a coolant leak on the front of my motor. I did a little research and found there is actually a tsb report about a cracked engine block due to casting porosity problem. So I took it into my Honda dealership and they confirmed that this was in fact the problem and proceeded to try and charge me $5500.. oh wait they were going to cover 25% how nice. Before I left I had got them from 25-40% but to me that is still unacceptable. According to the actual Honda service bulletin, which was issued in May 2008, actually circles the exact spot where my leak is and still refuses to cover the cost due to my mileage. I think this is outrageous!! the tsb verifies that Honda knows this a problem although they will not step up and fix their known defect..
