9. Nissan Sentra

Claim frequency: 23

Like the Aveo, the Nissan Sentra is also a small car. According to Brauer, when manufacturers crash test small cars like the Sentra, they normally test them in collisions with other small cars. This means that crash tests may not be the most reliable indicator of a vehicle’s susceptibility to personal injury crashes.

“When a vehicle is crash tested, it hits either a stationary barrier or another vehicle of roughly the same size and weight,” he said. “This means crash test ratings do not take into account what happens when two vehicles of different sizes collide.”
