Electrical System Issues

Frequent complaints involve the **electrical system**, including persistent **passenger airbag sensor malfunctions** leading to non-deployment or erroneous deployment. Issues with the **ignition switch/key not releasing** are also common, often linked to the shift interlock mechanism. Estimated repair cost: $400 - $700.

Brake Light Switch Failures

Multiple recalls address the **brake light switch**, which can lead to failure of the brake lights, prevent keyless ignition start, and disable shifting out of park. It can also affect the Eyesight Driver Assist System's pre-collision braking. Estimated repair cost: $150 - $250.

Owners have reported spontaneous **windshield cracking**, sometimes at very low mileage. Estimated repair cost: $400 - $600.
