Brake System Malfunctions (Vacuum Pump Failure)

Owners frequently report issues with the braking system, including a spongy pedal, reduced brake assist, or complete loss of braking power. This is often attributed to a failing brake vacuum pump, which can also lead to engine damage if oil leaks into the vacuum system. Critical recalls have been issued for rear brake caliper pistons and fuel pump issues, further highlighting brake system vulnerabilities. Estimated repair cost: $500 - $1,500.

Engine Stalling and Loss of Power

A significant number of complaints concern the engine, specifically issues like stalling, sudden loss of power, and rough idling. These problems can stem from various components, including the fuel pump (subject to recall), ignition system, or sensor failures. Early-life failures are noted. Estimated repair cost: $800 - $3,000+.

Electrical System Failures

Owners report a variety of electrical system problems, including issues with infotainment, power windows, lighting, and various sensors. These can be intermittent and challenging to diagnose, often indicating wiring harness issues or module failures. Estimated repair cost: $300 - $1,000+.
