Service Brakes Issues

Complaints include extended braking distances, a soft or loose brake pedal, and unintended brake activation. These issues can compromise stopping power and increase accident risk. Estimated repair cost: $400 - $800.

Forward Collision Avoidance (PCS) System Malfunction

The Pre-Collision System (PCS) can unexpectedly activate and apply the brakes, often due to misinterpreting road joints as obstacles. This can lead to sudden, unintended braking. Estimated repair cost: $500 - $1,500.

Airbag System Malfunction

Reports indicate that airbags may fail to deploy during a crash, a concern addressed by recall 20V024000 concerning the Air Bag Control Module. This significantly increases the risk of occupant injury. Estimated repair cost: $700 - $2,000.

Vehicle Speed Control Issues

Some owners have reported unintended acceleration or hesitation, which can be related to the throttle body or electronic throttle control system. Estimated repair cost: $300 - $700.

Interior Material Wear

Certain interior trim components, such as door handle covers and cup holder surrounds, may exhibit poor durability and wear prematurely. Estimated repair cost: $50 - $200.
