2013 Lincoln Navigator

I am submitting this complaint regarding a safety-related braking system issue with my 2013 Lincoln Navigator (VIN: [XXX]), which has fewer than 90,000 miles. The vehicle's brake control module, which is associated with critical safety functions including the anti-lock braking system (ABS) and traction/stability control system, required replacement. After a nationwide backorder and obtaining the replacement part through Gullo Ford in Conroe, Texas, an independent repair facility attempted replacement of the module on three separate occasions. The facility was unable to successfully program the replacement module and ultimately advised me to take the vehicle to an authorized Ford dealership. The vehicle was delivered to Gullo Ford on July 6, 2026, and remained there until July 20, 2026. Gullo Ford replaced the module for a fourth time but was also unable to successfully program the replacement module. The Gullo Ford repair invoice specifically states that they were "unable to complete programming due to Ford software issues with IDS" and that "Ford is aware of the issue and is working on a fix." I subsequently contacted Ford Motor Company and opened Customer Care Case [XXX]. At this time, I have not been provided with a repair solution or a definitive timeframe for when Ford will be able to correct the software/programming problem. The affected module is associated with the vehicle's anti-lock braking and traction/stability control safety systems. An authorized Ford dealership has been unable to restore these systems to proper operation because Ford's own diagnostic/programming software reportedly cannot complete the required programming. The vehicle was dropped off again on 8/10/2026 to Gullo Ford as it is unsafe to drive and no resolution has been provided.

VEHICLE DOWNSHIFTED WHILE DRIVING. SPEEDOMETER STOPPED WORKING. STOPPED THE VEHICLE AND THE TRANSMISSION FAILED TO SHIFT OUT OF GEAR UPON ACCELERATION. CLUSTER SHOWED WRENCH AND ENGINE LIGHT. TURNED THE VEHICLE OFF THEN RESTARTED AND THE CLUSTER CLEARED AND OPERATION RETURNED TO NORMAL. A WEEK LATER, THE SAME INCIDENT. SEEMS TO BE THE PROBLEM THAT EXPIRED IN THE 2023 CUSTOMER SATISFACTION CAMPAIGN; HOWEVER, THE VEHICLE IS OUT OF THAT WINDOW.

While operating my 2013 Lincoln Navigator under normal driving conditions, a spark plug ejected from the cylinder head, causing immediate and catastrophic engine failure. The engine lost power and began producing severe mechanical noise, creating a potential safety hazard due to sudden loss of propulsion. Inspection by both an independent mechanic and an authorized Ford dealership confirmed that the spark plug ejection allowed debris to enter the combustion chamber, destroying internal engine components. The vehicle was properly maintained and this failure occurred without warning. This issue appears consistent with known problems involving the Ford 5.4L Triton engine design. Ford Motor Company has refused to escalate or investigate the failure despite documentation. Ford Motor Company Customer Relationship Center P.O. Box 6248 Dearborn, MI 48126 Re: Goodwill Assistance Request & Notice of Latent Defect Vehicle: 2013 Lincoln Navigator – 5.4L Triton V8 VIN: [XXX] Case Number: To Whom It May Concern, I am the original purchaser and continuous owner of a 2013 Lincoln Navigator equipped with the 5.4L Triton engine. For more than three decades I have exclusively owned Ford and Lincoln vehicles, including multiple Lincoln Navigators, Ford Expeditions, and Ford trucks — all purchased new. I also still own a 1991 Ford Mustang 5.0 GT Convertible acquired new in 1992 and a 1999 Ford pickup currently exceeding 350,000 miles. My history reflects long-standing brand loyalty and confidence in Ford durability. This Navigator has been properly maintained throughout its life. Oil changes were performed approximately every 3,000 miles by both independent mechanics and authorized service facilities. The vehicle currently has approximately 140,000 miles and remains in exceptional cosmetic and interior condition. The vehicle has never been used for towing or severe duty. While operating under normal driving conditions, the check engine light illuminated and the engine imme INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

While driving at approximately 65-70 mph on a major interstate, the engine experienced a sudden catastrophic failure without warning. This caused an immediate loss of power and power steering/braking assist, making the vehicle extremely difficult to control in high speed traffic. This sudden stall endangered my life and the lives of nearby motorists. A certified mechanic inspected the engine internals (via borescope) and identified that a valve seat had dropped in the #4 cylinder, causing it to impact and destroy the piston. This 'dropped valve seat' failure is a known defect in Ford/Lincoln 5.4L engines. It occurred despite my meticulous maintenance history and constitutes a latent manufacturing defect that creates an unreasonable safety risk on public highways.

My truck on a few occasions suddenly down shift hard and on its own without warning, it could very much have cause an accident and could have been deadly at highway speeds, at the same time the speedometer would go to 0 and quit working, as well as multiple warning messages would pop up on message display. IE out of fuel, air system failure, orange wrench, Etc. Then after some time everything would go back to normal operation until it randomly did it again. This is a major safety issue for drivers and passengers as well as other vehicles around. At the dealer they gave me a print out from 2019 that states it was a safty recall 19S07 but the dealership said it was only a technical bullet not a safty recall and dealers not responsible for the cost but will reprogram the Powertrain Control Module (PCM) with updated calibration -Requires using IDS software release 113.06A or newer (internet connection needed) -No replacement parts needed—this is a software fix But in truth, this dose not fix the problem. Online research show that in most cases the dealership has to remove main control and replace LEAD FRAME. (Located internally in the transmission) like they did on my SUV as well. The cost is over $1,500 and Ford and Lincoln are down playing the danger and by making customers pay out of pocket since it is not an official safety recall from the nhtsa. This out of pocket cost may lead to people not repairing the faulty system. This could have and could be causing accidents or maybe even deaths..This is crazy not to be a full safty recall... Sudden downshift at highway speeds could be extremely dangerous for everyone. Ford/Lincoln should be held responsible for the faulty part and repair for safty purposes.

As per Ford Customer Satisfaction Programs 19B05 and 19N01 down shift and molded lead frame. My truck was brought into the dealership to verify the problem. Codes revealed that the molded lead frame and output sped sensor went bad. My 2013 Navigator has 62,000 miles. It was determined that my vehicle was 60 something days over the time limit for the repair and I would have to pay the $1500 to cover the repair! Now I see Ford is issuing a recall! I had the vehicle at the dealer waiting for weeks to get the part. I took the vehicle back as the service advisor told me they did not know when the parts would arrive. I was driving the vehicle several days after picking it up and the rear wheels locked up doing 45 mph. The vehicle behind me hit the back right of my vehicle causing $1900 worth of damage!

I have had this issue happen 3 times the last couple of months.this last time I was driving in traffic and all of a sudden, the motor started humming like it was in neutral. In just a second or two I thought maybe I hit the gear shift, but I had not. I pulled over and turned the car off. waited a couple of minutes, then started it again. As I pulled onto a busy street, I pushed the gas to go and it happened again. this time i am in traffic where I cannot pull over, pressed the gas again hoping it would go as traffic was coming behind me. The car then jumped and started to act like it was getting to much gas. so i let off the gas again, it then was rolling and i barely pressed on the gas and it seemed to be normal. I drove it to my mechanic and he kept it for a week drove everywhere, no problem. i pick it up and it did the same thing sounding like it was in neutral, then was ok.

The contact owns a 2013 Lincoln Navigator. The contact stated that while driving at 30 MPH, the rear wheels seized and the vehicle made a screeching sound. The vehicle was taken to the dealer and diagnosed with wheel speed sensor failure. The contact was informed that the wheel speed sensor needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was notified of the defect and directed the contact to file a complaint with the NHTSA. The failure mileage was approximately 140,000.

WHILE DRIVING ON ACCESS ROAD ABOUT 45 MPH THE CAR JOLTED VERY HARD CAUSING ME TO NEARLY LOSE CONTROL COMPLETELY. THE SPEEDOMETER WENT TO ZERO AND IT SEEMED LIKED THE TRANSMISSION DOWNSHIFTED TO 1ST GEAR THEN IT WOULDN'T MOVE. I PULLED OVER AND CHECKED UNDER AND ALL AROUND CAR AND TURNED IT OFF AND RESTARTED IT. IT SEEMED FINE FOR ABOUT 2 MILES THEN DID SAME THING. I TURNED CAR OFF AND CALLED TOW GUY TO TAKE IT HOME.

TL* THE CONTACT OWNS A 2013 LINCOLN NAVIGATOR. WHEN THE FRONT PASSENGER SEAT BELT WAS REMOVED WHILE THE VEHICLE WAS IN MOTION, THE WARNING INDICATOR DID NOT ILLUMINATE. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE VEHICLE WAS OPERATING AS DESIGNED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND CONFIRMED THAT THE VEHICLE WAS OPERATING AS MANUFACTURED. THE FAILURE MILEAGE WAS APPROXIMATELY 35.
