The vehicle would not rev past 3,000 rpm in any gear or while stationary, with the engine behaving as though it was hitting a rev limiter.

The engine reached approximately 3,000 rpm and would surge as though against a rev limiter rather than continuing to climb. The threshold dropped to around 2,600 rpm when the engine was cold. There was no excessive smoke and no fault codes related to the concern, with the brake light circuit confirmed operational and the vehicle not in limp mode.
