P0954: Auto Shift Manual Control Circuit Intermittent
What to do
Note whether the paddles fail at particular steering positions — on a turn, or with the wheel straight. That pattern points at the clockspring behind the steering wheel rather than at the paddles themselves.
What this code means
The manual shift control behaves inconsistently — paddles that work sometimes and not others, or occasional shifts nobody asked for. A clockspring beginning to fail is the classic cause, and it typically misbehaves at particular steering angles rather than randomly, which is a diagnostic detail worth capturing.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
