Air conditioning/heater, defroster fan stops working. It sounds as if the fan motor is struggling and then it turns off and won?T turn back on for the remainder of the day.

The contact owns a 2008 Honda Civic. The contact was driving 55 mph when the air conditioner stop working and then stalled. The check engine lamp was also illuminated and the contact noticed that the vehicle was overheating. The vehicle was towed to the dealer who diagnosed that the engine cylinder block was cracked and as a result, the cooling was leaking. The manufacturer was contacted who offered to pay for a portion of the repairs. The vehicle was not repaired. The failure and current mileage was 58,878. Updated 07/01/11

I have a 2008 Honda Civic ex. Around 70,000 miles my engine overheated on the highway. Upon further inspection there was radiator coolant leak from underneath my car. The Honda dealers stated there was a crack on the engine block. I investigated this matter on the internet and there were numerous complaints of cracked engine blocks on the 2008 Honda Civic. Due to numerous complaints Honda extended the powertrain warranty to 8 yrs for unlimited miles. There is currently no recall but there should be in my opinion. Also I have replaced all four tires on my 2008 Honda Civic twice in about 70,000 miles due to uneven wear (inner flat areas on the tires) even with tire rotations and alignments. There are also numerous complaints about extreme uneven tire wear on the internet.

I have a 2008 Honda Civic with a little over 20,000 miles. Initial symptom was A/C fan would shut it's self off and on. Dealer replaced a part in the fan motor. Less than two weeks later it began again. Then on a Sunday the A/C began to work intermittently. I took it to the dealer the next day and said that I noticed when at high speed A/C stops working but works at low speed when exiting highway. Dealer said there was a service bulletin and ran a couple of software updates and said it was working again. When I picked up the car the problem recurred and I returned it to the dealer same day. This time the dealer determined it was a cracked block. They said it was a known problem with the coolant system and if I had continued to drive the car it would have overheated and I would have been on the side of the road. The dealership was very helpful and gave me a car to drive while mine was being repaired. They said that the new block will continue to be covered under the drive train warranty. My concern is that if this is a design flaw and a known issue, it may happen again and I will be on the side of the road possibly without warranty coverage.

A/C failure in 2008 Honda Civic. Dealer claims rock hit A/C condenser and punctured so coolant ran out. No warranty service available. Suggested my insurance might cover. Searched online and found many others with same issue, exact same diagnosis. Seems to be design flaw where condenser exposed with no protective grill. Or condenser made of faulty material and somehow failing with no rock involved at all. Strange to see so many people with same diagnosis and Honda doing nothing about it. At minimum, Honda should recall to install protective shield for A/C condenser. Instead, they'd rather charge $600+ to keep repairing them. Instead of a recall / bad publicity / cost to Honda, they'd rather keep riding this cash cow. What a win for Honda!

Coolant leak - I have about 32,000 miles on the car - still under warranty. I noticed coolant leak from engine block. Took car to Honda dealer - they were aware of the problem and are going to correct it. There were no recalls for this failure.

Small pebble hit condenser on my 2008 Honda Civic while driving unbeknownst to me. The dealer says it has caused a small hole in condenser and has to be replaced. On examination damage is not readily noticeable. The car is only 3 mos. Old. I feel this is a design flaw, and have noted that many others have complained about the same problem, so it quite common. I think Honda should address the problem and fix it, and have it covered by warranty.

I took my 2008 Honda Civic into the dealer because the air conditioning wasn't working. They said it wasn't working because there was a hole in the ac condenser and that this wasn't covered by warranty. They indicated that this was a problem with Honda but that this design defect wasn't covered by warranty. They could not guarantee that this would not happen again and again due to the defect but that it would not be covered under warranty. This would seem to me to be a good reason for a recall to fix the design problem if the ac unit is so vulnerable to puncture given its location and lack of protection from road debris.
