Service bulletin ACA07212016901

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

American Honda Motor Co., Inc., Case No. 3:12-cv-1377-SI (N.D. Cal.). The piston rings on certain cylinders may rotate and align which can lead to spark plug fouling.

A16-0602017-07-31. Service bulletin. Service bulletin - A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60mph. The problem is typically diagnosed as a bad torque converter. American Honda investigated the judder and found that the torque converter was not causing the judder; rather, it was caused by deteriorated transmission fluid. The transmission fluid deteriorates quicker than expected when it is exposed to intermittent high heat loads under specific driving conditions. American Honda is working on a software update that will maintain the transmission fluid temperature within the desirable range under all driving conditions and eliminate the potential for this judder. American Honda will revise this service bulletin when the software update is available.
