Inspect the electrical
What to look for: Dim or flickering dash lights at idle, slow window operation, intermittent infotainment glitches, parasitic battery drain (dead battery after a few days parked). (5 owner complaints on this vehicle
· typical repair $850 · failures cluster ~6,000 mi)
On the test drive: Cycle through every electronic accessory during the drive — heated seats, defrosters, climate fan on max, cruise control. Glitches show up under load.
What to look for: Pulsing brake pedal, pulling to one side when braking, squealing or grinding, soft pedal that goes to the floor. (3 owner complaints on this vehicle
· typical repair $450 · failures cluster ~2,000 mi)
On the test drive: Hard brake from 40 mph in a safe spot — pedal should be firm, stop should be straight. A pulse means warped rotors ($300–$600).
