My 2005 A/C quit and the dealer said it was due to a leak in the condensor caused by "road damage". A small hole was found which caused the coolant to leak out. The condenser is exposed by 6 grill openings on the 2005 and down at the bottom close to the road. I have read many issues with A/C coolant "leaks" and perhaps this is occuring on other Muranos. The unit was relaced for $800 and I'm filing a report with Nissan consumer group to have it covered under warranty (16K miles), as mentioned the dealer claims it was "road damage" and thus not covered. My concern is what will keep it from occuring again - Is the condenser material that fragile? Advice welcomed.
