What 2015 Scion tC owners say
Transmission & drivetrain
Whining noise is heard when the clutch petal is released. Noise is coming from the input shaft bearing. Common failure on this model. Mechanic confirmed that is the issue. If the bearing completely fails could leave the car stranded and cause more damage to other transmission components. No warning lights but noise is very loud.
My 2015 Scion tC automatic has rough shift points, rough idle at stop signs. The Scion frs has the same issues and Toyota issues a TSB for shift enhancement that fixed their transmission rough shifts and rough idle. I'm hoping that Scion or Toyota are listening and we need this fix too! Resetting the computers by disconnecting the battery fixes the issue temporarily, since this is a 'learning' transmission, it always seems to default and starts to shift rough, shift too often or back to back even in city driving. It's gear hunting and I'm so sick of it. Toyota said they can't find anything wrong, I did a transmission drain and fill with Toyota thinking it would fix the issue and it never did. It's the ECU or TCM, we need the update just like you guys did for the frs and you fixed those issues! So please fix ours! These rough shifts are annoying. …
