RepairPal Expert Overview
270 vehicles are being recalled because the engine could fail prematurely due to an internal component failure.
Honda will notify owners of affected vehicles beginning September 16 2013. If don't receive notification and you feel you should, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call. The Honda recall numbers are JB4 for the Odyssey and JB5 for the Pilot.
The pistons are one of the main components in the lower section of the engine, there is one piston inside of each cylinder. It is possible that some pistons were not properly heat treated during their manufacturing process. This would reduce the hardness of the metal making it more susceptible to premature wear. A worn piston may fail unexpectedly causing the engine to stall, increasing the risk of a crash. Dealers will replace the lower part of the engine assembly, the "short block", to correct this concern.
