The vehicle has a severe brake fluid leak. There is a recall for the issue. I called the local Lincoln dealership Ford Mill Lincoln SC and they said there was nothing they could do. I explained to them that there was a safety recall. They refused to fix the vehicle under the recall. The car is very unsafe to drive and the manufacturer is not offering any assistance to fix the defect.

The brake booster on a 2017 Lincoln Navigator does not work properly, causing increased force to brake, a brake pedal that does all the way to the floor, and increased distance to come to a full stop. A recall was issued (22V-150/22S11) on the master cylinder and brake booster. The master cylinder was replaced in November 2022 (prior to my ownership) but not the brake booster. The brakes have been an issue since I purchased the car in January 2023. I tried several times to get the dealership to assist me but was never able to get the help that I needed. I recently took the car in to have the brakes addressed and now have to pay out of pocket to have the brake booster fixed. I was told that the warranty for a recall is only good for 12 months which I was never informed of at the time of the vehicle purchase.

The brakes on my car stopped working and this caused me to crash into a wall. This accident caused by my brakes failing nearly killed me and put others at risk. There were no recalls, or warnings about the brakes failing before the accident.
