Bulletin Summary
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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
