Noticed vehicle left a large puddle in the driveway. Checked under hood and it appeared something had leaked/sprayed in the engine compartment towards the passengers side. Took to mechanic. Diagnosis of problem (paraphrased as best as I can recall)- transmission cooling part failed and leaked into radiator causing trans fluid and antifreeze to mix, flow through engine and spray out. Mechanic stated it's something he doesn't see often and it's a major repair (think 1k). A quick search of the internet shows this is an issue with 05 Honda Pilots and that Honda is not taking responsibility for it. This is obviously a design flaw or defect and they are doing nothing. Hopefully the problem was caught/addressed in time to repair without having caused additional major damage to my engine. Unacceptable.

2005 Honda Pilot radiator coil failed causing fluids to mix and transmission to fail. Repair shop indicated that radiator had prematurely deteriorated causing failure. Had a new radiator installed at $500- system flushed multiple times. . . . Just about a month later- radiator failed again. Replaced but vehicle is still not running well. At @40 mph vehicle seems to randomly "rev and stick"- let off gas and it passes.

Radiator was apparently struck by rock and cracked. The Honda Pilot was immediately towed to dealer for factory replacement. Within two months the new radiator was severely damaged and cause of crack was undetermined. After searching the internet auto blogs there appear to be numerous complaints regarding cracked radiators in Honda Pilots from random road debris. This does not appear to be common in the accord or other make and model vehicles suggestive to me that the repeated occurrence of cracked radiators in the Honda Pilot is a result of faulty design. This could lead to serious engine damage or injury if this continues.

I had to replace my radiator at 37228 mileage and 85031 on 2005 Honda Pilot. The radiators are failing at the transmission fittings attached to the bottom of the radiators. There are several thousand complaints about this issue and Honda is denying there is a problem. The problem is the transmission cooler is built into the bottom of the radiator. The cooler sits in the bottom of the radiator. There are two transmission fittings on the out side of the radiator that attach to the transmission. This brings transmission fluid in the radiator cooler, cools the fluid and returns it to the transmission. Now inside the bottom radiator sits the transmission cooler which is just a small pipe witch is attached to the transmission fittings. When the fluid enters the radiator cooler it gets instantly cooled and returned to transmission because the cooler is submerged in radiator fluid. This is because the bottom of the radiator is the coolest at the bottom. What's happening is the transmission fittings are rusting away and failing allowing radiator fluid to enter the return line to the transmission. When radiator fluid enters the transmission the transmission is done. You need a replacement. These problem is happening to several Hondas and nissin. The two car company's use the same manufacturing for the radiator. The company is dense. The failing on Hondas and Nissan. If you look into this matter you will see how many people are affected by this. I replaced two radiators for this truck so far. Please look into this problem for $1400 so far. There is a defect with this radiator and Honda refuse to do anything about it. People are spending thousands of dollars for something that could be fixed by Honda and Nissan. Please issue a recall with this issue. Thank you.

Radiator failure due to lack of protection, resulting in puncture, loss of coolant and engine over heating. Possible engine fire.
