Service bulletin 05-002-21-3854

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.

NHTSA's summary

Automatic Transmission/Transaxle Cooler and Lines Flushing Procedure: Automatic Transaxle/Transmission (A/T) oil cooler and lines must be power flushed completely before an overhauled or replacement A/T is installed (except SKYACTIV-DRIVE). The most common cause of repeat A/T failures is lack of lubrication to the front and rear planetary gears. This is usually caused by an accumulation of metal particles and debris (from a previous A/T failure) on the internal mesh type baffle of the oil cooler. Power flushing will remove the restriction by back flushing, followed by forward flushing to dislodge a restriction, then back flushing again. This will in turn ensure full ATF flow for the transmission when it is operating.

SA-079-242024-11-04. Service bulletin. The SKYACTIV-DRIVE FW6A-EL AT uses “Automatic Transmission Fluid (ATF) Type: FZ”. Only use “ATF-FZ” to fill or top off the fluid level. ATF-FZ is specially designed for use in the SKYACTIV-DRIVE series AT. It is a low viscosity formula with less friction for better fuel economy. NOTE: ATF-FZ is colored blue for easy identification.
SA-052-242024-09-04. Service bulletin. Some customer's might state that they notice fluid or oil leaking/dripping on the ground when the vehicle is parked. For this concern, inspect the vehicle for any trace of a fluid or oil leak and use the following examples as a guide to determine if it is severe enough to require a repair, or just to clean the area and monitor it at the next service.

01-010-222022-10-06. Service bulletin. Some customers may experience a squeaking noise may be heard from the exhaust manifold when the idle speed drops from fast idle to normal idle speed during cold start. This is caused by a variable valve being stuck in the closed position. When returning from fast idle to normal, the stuck valve suddenly opens due to thermal change around it which causes abnormal noise. To eliminate this concern, the internal design of the exhaust manifold has been modified.
