Symptoms to watch for
- Yellow 'Power Limited' warning appearing on the digital instrument cluster while driving, most often reported at highway speeds
- Noticeable reduction in available torque and acceleration accompanying the warning
What To Check
Genuinely test-drive-detectable if it occurs, provided the test drive includes a sustained highway-speed segment - a purely urban/suburban test drive would not necessarily reveal it, consistent with this platform's general guidance to match test-drive conditions to a vehicle's real-world use case.
