Transmission

Bob-Boyd Lincoln is phenomenal. While it is unfortunate that these complex machines can be imperfect, I've always had such a great experience with the dealership. Whether it is the sales department or the service department, their customer service and willingness to go above and beyond is second to none. This website is cute, but why don't you reach out to the dealer? I'm certain they will do everything they can for you. They always have for me.

On August 31, 2026, at approximately 11:07 a.m., the vehicle had been parked and was stationary with the engine running. After remaining stationary for a short period of time, the vehicle suddenly and unexpectedly moved backward rapidly on its own. I did not intentionally command the vehicle to move backward and I did not press the accelerator. While the vehicle was moving backward, I pressed the brake pedal twice in an attempt to stop the vehicle. The brake pedal felt soft, as though there was little or no braking resistance, and the vehicle did not respond to my braking attempts. Immediately afterward, the vehicle unexpectedly moved forward and struck a vehicle in front of it. That vehicle was then pushed into another vehicle. The cause of this incident is currently unknown. I am concerned about a possible braking-system failure, unintended vehicle movement, powertrain/transmission control malfunction, electrical/electronic control malfunction, or other vehicle-control defect. The vehicle is available for inspection. I have requested that the dealer preserve all electronic and diagnostic data before any repair, reset, software update, or reprogramming is performed.

Placing the vehicle in reverse we backed into a concrete piller and none of the safet sensors allerted us to the object.

Was operating the vehicle around a slight bend at about 45mph. The brakes and steering then stopped working and was non responsive. The vehicle was sliding off the road toward a parked dump truck. After about 2 or 3 seconds the steering and brakes started working again and I regained control of the vehicle. I then fishtailed across 2 lanes of traffic and managed to keep the vehicle straight. Immediately after a warning popped on the dash stating "Drive control fault service required." Upon calling roadside and bringing the vehicle to the service center the following was identified. The Vehicle Dynamics Control Module (VDM) failed. This caused the vehicle to detect a rollover, which means the vehicle took control of the steering and brakes according to the service manager and would not allow the driver to intervene. This module was replaced. A cause for the module failure could not be found. The module was not allowed to be inspected and was sent to Lincoln corporate. The service tech was not allowed to open the module and identify the reason for failure. The risk for this part failing means that steering and braking are non operational. In my situation this was potentially a lethal accident with myself and family in the car. To slide off the road and hit a parked dump truck surely could have been life ending for myself and others. Vehicle diagnosed for DTC C1112:92 in the VDM The problem was not able to be reproduced. A cause of the problem has not been identified and is not known. The service center sounded concerned that they could not find the reason for failure and could not confirm it wont happen again. The vehicle was only inspected by the service center. There were no prior symptoms or warning lights or messages prior to the module failure.

On Tuesday, May 5 2026 upon entering the vehicle, my wife closed the drivers door at which time the rear windshield exploded. The vehicle is scheduled for an appointment on Monday, May 11, 2026 at Porterville Ford for inspection. Approximately 50% of the glass came out, both inside and outside the vehicle. If my children were there, they would have been covered in broken tiny pieces of glass. This vehicle has just over 6,000 miles since new and has never had any damage to the glass. I have researched online and there are many other instances where this has happened, often siting incorrect or too tight of installations where the pressure from closing a door shatters the tempered glass.

Additionally, the vehicle jerked violently while accelerating and while reversing on a hill. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and advised the contact to take the vehicle to the dealer to be diagnosed. The failure mileage was approximately 500.
