P1299 — manufacturer-specific powertrain code

P1299 is a manufacturer-specific powertrain code: it is defined by the carmaker, not by the OBD-II standard, so the same code can mean different things on different brands. Below are the vehicles and failure patterns where owners report it, drawn from NHTSA complaints — the most reliable guide to what it means in practice.
