Service Brakes problem #1

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.

Service Brakes problem #2

This vehicle has been returned to service 5 times. It is currently in service for the same 4 issues that it was taken to service for the very first time on 12/10/2025. This includes inappropriate braking on the interstate, driver window malfunction, the key intermittently stops working, and the connectivity does not regularly work. In addition to these 4 issues, the main screen in the car stopped working and the rear vox screen has stopped working. Based on state law, Lincoln should have bought the car back, as I have had it for just over 2 months. As of February 2nd, 2026 the car has been returned to service 5 times and has been back to the dealership for service for 37 days and still counting since the original pick up date of 11/21/2025. The dealership has not honored their commitments with black label service. I was upsold on the vehicle for this service. On multiple occasions I have not been provided the delivery that is included. I was told by the assistant manager that this service would include a Lincoln Navigator brought to my location. The gm informed myself and my husband that they do not have to honor that. They offered a car that did not legally fit my 4 children in the backseat. Eventually, after many phone calls, they offered a much smaller aviator. The service manager stated they they attempted 3 different eyeballs. When questioned on dates that they provided to Lincoln, he became very defensive and hung up on me. My husband and I attempted to meet with him in person at the dealership. After being told that he would meet with us and then waiting 3 hours, we had to leave. The gm did not provide assistance with this, as he stated he was in a meeting. The gm and assistant manager have both stated that we have no legal recourse, as I signed an arbitration agreement.

Service Brakes problem #3

The contact owns a 2025 Lincoln Navigator. The contact stated that while driving in the driveway at approximately 2 - 3 mph, several brake warning lights were illuminated, and the vehicle failed to respond immediately while depressing the brake pedal, which required the contact to exert an excessive amount of pressure on the brake pedal. The messages "auto-hold disabled", "brake function failure" were displayed, and unknown warning lights were temporarily illuminated. The vehicle was not diagnosed or repaired by the dealer or an independent mechanic. The manufacturer was informed of the failure and a case was filed. The manufacturer confirmed that the VIN was not under recall. The failure mileage was approximately 2,000.
