Ticking noise on cold start up as well as reduced acceleration speed and torque. Diagnostics point me to believe the AVCS solenoids are beginning to fail prematurely. This has not been confirmed by a dealership and the issue is reproduced during any driving. There are no CEL lights active or codes stored. The vehicle currently has 74,*** miles. The issue started within the last 6 months. This is a safety concern when attempting to get up to highway and freeway onramps or getting up to merging or passing speeds.
