Contacted the Service Mgr at the Kia Dealer to inquire if he had any knowledge of the Cold Downshift issue. He had not, he did mention the Shutter issue many owners of this model have reported, but not the Abrupt cold downshift issue I have been experiencing. He reviewed all Factory Bulletins, and just so happened the Kia Factory Agent was in the shop....and he hadn't heard anything either. The Service Mgr was prompted from Shp Forman....and had worked on Niro's. Speaking out loud he said, can't be Fluid (I thought the Canister you see was also the Fluid level for Transmission, its only for the Hybryd system)..and no way to visibly see Transmission Fluid level...without opening Transmission...but he said, if that were the cause, the Downshift would continue even after a few stops... He mentioned a Solenoid that I think he said controls Gears 1 and 3 shifts...but no explanation if that were so why after 2 or 3 Cold Downshifts, or, using the car everyday...the Cold downshift issue was not present. Again, if the car sits unused 2 to 3 days or more, the Cold Downshift, the last downshift before coming to a stop is very abrupt (Serviced Mgr said that was shift from 2 to 1). The Solenoid is Internal and means a Teardown... not sure I would opt for that...rather I would either make sure I drive car everyday, even if just around the Block, or just put up with the issue. I have not had good luck getting issues with cars resolved when a Major teardown...was required to fix an issue....even to the extent of making the issue worse, or, causing new issues. Other than this cold downshift issue, I really like the Niro...I average 48 MPG, its nice ride, well built vehicle. I just feel like this is the saying, let new technology have a few years to get out all the bugs before buying. I do Plan to trade in 3 yrs....so holding off any Major teardown.... I have 2 yrs to go.
