Everytime I start my vehicle the parking brake fault service now light comes on.
The vehicle experienced a sudden unprovoked, catastrophic, and total electronic and mechanical failure of the primary braking and adas. Driving at expressway speeds, the vehicle immediately lost all power brake assistance, threw immediate multi-system critical alerts on the instrument cluster, and became instantly undrivable. The vehicle is available for inspection at a local licensed Lincoln dealership service center. The failure occurred completely without warning while navigating heavy traffic at active highway speed on the expressway. The instant loss of power braking functionality dramatically extended the vehicle's stopping distance and significantly reduced control of a SUV in a high-speed environment. This sudden, unmanaged deceleration created an immediate, life-threatening risk of a high-speed rear-end or multi-vehicle pileup, placing the occupant of the vehicle and all surrounding motorists in extreme danger of severe injury or death. The driver was able to bring the vehicle to a stop in a precariously exposed location on a very narrow shoulder when one became accessible. Miraculously, the vehicle was not struck by fast-moving trucks while waiting for a tow-truck. Yes. The local authorized Lincoln dealership service technician team has confirmed the catastrophic code failures. Due to the severity and complexity of the total system shutdown, the local dealership escalated the vehicle to Lincoln factory corporate engineers. However, the root cause of the catastrophic failure was never identified and the technicians and engineers have given up further attempts. There were absolutely zero pre-existing symptoms, warning lamps, soft codes, or performance degradation prior to the exact moment of the failure. The system failure was instant. The instrument cluster simultaneously illuminated multiple critical alerts, including the primary braking system warning, abs fault, and esc failure alerts, accompanied by an immediate audible safety chime.

Brakes were engaging automatically and dashboard showed fault messages including "antilock brake fault" and "pre-collision assist not available.

If this incident had occurred on a highway it would have been extremely dangerous since the brakes were being engaged without driver knowledge and input.
