An XPENG X9, boasting a price tag exceeding RMB 400,000, suffered a catastrophic rollover and was left almost completely wrecked. This occurred after the vehicle swerved sharply to avoid a concrete mixer truck and subsequently crashed into a greenbelt, trees, a utility pole, and rocks. The incident unfolded at a speed of roughly 87 km/h. Although the occupants briefly lost consciousness, they emerged unscathed, remarkably without any of the vehicle's airbags or head curtains deploying.

The owner, Mr. Liu, firmly rejected XPENG's post-sales explanation, which attributed the non-deployment to insufficient impact force and incorrect collision points. XPENG officially responded by stating that the accident did not satisfy the activation criteria for the airbag collision sensors, while also expressing respect for the owner's decision to commission a third-party agency for evaluation.

The crux of the disagreement lay in whether the severity of the vehicle's damage should have been sufficient to trigger the airbags. Mr. Liu voiced concerns that data might be tampered with or erased during the manufacturer's inspection of the vehicle's computer module. As a result, he preferred to shoulder the expense of commissioning a qualified third-party agency for an independent evaluation.

It was proposed that both parties could jointly seal relevant physical evidence prior to inspection. If necessary, they could also apply for evidence preservation or seek judicial expertise to ensure an objective and fair assessment. This would help clarify core issues, such as whether the collision data corroborates the manufacturer's judgment and whether the airbag system functioned as intended.
