Recent owner reports: Service Brakes

“The vehicle exhibits dangerous electronic malfunctions. A licensed technician (MV-113255) has confirmed a sporadic unintended acceleration defect where the cruise control 'decrease' button causes the vehicle to increase speed.”

“Pulled up to gas pump, put parking brake on (manual transmission), got out of car and heard a beeping noise from inside. The car then began to drift backwards into traffic. Have DashCam video that can share.”

“I was driving between 40-50 MPH at a consistent speed and I began to have to put the brake pedal to the floor in order to slow down the car. Even when doing this the car does not slow down at the rate expected and stopping distance has increased by more than 50 percent.”
