Ford Expedition collision warning problems

Filed Oct 27, 2026 · Brakes, Driver assistance · IA

On October 10, 2026, while traveling down the interstate at approximately 80 mph, the dash on my vehicle began flashing the following error messages: Service AdvanceTrac, Check Brake System, Service Vehicle Soon, Part Brake Limited Function Service Required, and PreCollision Assist Not available. Also showed multiple service needed icons. The car did not have any brakes. It did not appear to have the hydraulic fail safe functioning either. We put the vehicle in neutral and coasted. Once we slowed down to about 30 mph, the rear brakes only began locking up. We did have park on the transmission. Once we got stopped, we shut the vehicle off, which appeared to reset the electronic issues. We were close to home so we made it safely. On Monday morning, we had it towed to the local Ford dealership. The brakes were working again and the entire brake system checked out fine. They did replace the Electronic Brake Booster and say the issue is now fixed. I have been in contract with Ford Motor Company, as the vehicle is well within warranty, and they will not complete a buy back - which I disagree with as this should fall under the safety concern umbrella.

The transmission malfunctioned at highway speed on the highway. When traveling on the highway at approximately 45 mph in the middle lane, I accelerated moderately to reach 65 mph to safely change lanes. While accelerating to change lanes, the transmission dropped the gear and banged violently, causing temporary loss of forward drive and steering, causing excessive swerving. The collision warning system was beeping since the transmission surge was so violent. The vehicle has been into the dealer for transmission warranty repair before this issue. This issue has occurred three times since the repair. I have taken the vehicle in multiple times to correct the recurring error, but the dealer is claiming they can't reproduce the issue. The vehicle is now out of warranty, and they are claiming there is no issue.

On August 11, 2026 at approximately 5:17 PM, the vehicle was traveling about 25–30 MPH and approaching a stop sign. The driver began braking normally, but the vehicle did not adequately slow despite repeatedly pressing the brake pedal. The vehicle continued completely through the stop sign and intersection. Fortunately, no cross traffic was present and no collision occurred. After passing through the intersection, the vehicle slowed while traveling uphill. At approximately 5 MPH, the electronic parking brake automatically applied by the vehicle and brought the vehicle to a stop. After being placed in Park, the vehicle would not shift out of Park and displayed multiple fault messages. FordPass recorded simultaneous faults for Antilock Brakes, Electronic Parking Brake, Powertrain Malfunction/Reduced Power, Pre-Collision Assist, and Blind Spot/Cross Traffic systems. One message specifically stated that the anti-lock brake system had detected a fault and was disabled. After several power cycles, the vehicle could be moved, but an orange wrench remained illuminated and cruise control was unavailable. After being shut down for approximately one hour, the warnings cleared and the vehicle appeared to operate normally. There were no warning lamps, messages, or braking symptoms before the failure occurred. Because the vehicle failed to respond normally to braking and traveled through an intersection, the incident created a serious risk of collision, injury, or death. The vehicle was subsequently towed to an authorized Ford dealership and is currently available for inspection. Dealer diagnosis is pending. The dealer has been asked to preserve the diagnostic trouble code/fault history and investigate the brake, electronic brake booster/ABS, electrical, and related control systems.

The pre collision avoidance system doesn’t activate at all even though the adaptive cruise control works properly. Has been seen and evaluated by Dealership technician as well as having a Ford engineer remotely logged into the vehicle. All modules have been updated and the issue still isn’t resolved. I was told by the dealership to take it to a different dealer or figure it out on my own.

Forward collision system does not work or alert under any circumstances. Vehicle has forward collision mitigation as well as collision mitigation alerting, but neither systems work. Dealer able to verify these systems do not work, but have no recourse for repair, as Ford engineering has not provided a solution.

Since I purchased the vehicle brand new, none of the safety features have been functional. The following sensors are faulty and none of them have worked since I bought the vehicle: 1) Cross Traffic Alert; 2) Blindspot System Fault; 3) Pre-Collision Assist; 4) Front Camera Fault; 5) Parking Sensor Fault; 6) Lane Keeping Assistance. I tried to take the vehicle into the service department of the dealership to fix the problem several times, but as of this time, there has been no solution. The dealership said the problem cannot be fixed, because only Ford Corporation can create a computer software fix for the problem. I was instructed by the dealership not to bring the vehicle back for the same issues, because nothing can be done, and they will not touch it. However, Ford has failed to launch a computer software fix, since I had had the vehicle to 2 years. Since the dealership can't fix it and Ford can't fix it, I am stuck with a defective vehicle that is "Unsafe" to drive, because all of these safety features that are not functional help prevent and reduce the probability of motor vehicle accidents. Ford is refusing to help me and rejected my claim even though they can't fix it.

I bought this vehicle brand new in 2024 and none of the safety features are functional and can't be fixed. Ford corporation cannot find a a computer software fix for it and the dealership can't fix it. The vehicle in unsafe to drive. The following sensors are faulty and have continued to give failure alerts since I purchased the vehicle: 1) Cross Traffic Alert; 2) Blind Spot System Fault; 3) Pre-Collision Assist; 4) Front Camera Fault; 5) Parking Sensor Fault; 6) Lane Keeping Assistance, 7) Rear backup assistance. It is a safety hazard and unsafe to drive because none of the "Safety Warning" or "Driver Assistance" features work, that would help prevent accidents. For the past 2 years, I have been driving this defective vehicle that is a safety hazard, which is not repairable, nor is the vehicle marketable. I have tried to resolve this issue numerous times, but there is no solution. The dealership advised me to not bring it in for service again, because there is nothing that can be done. I tried to file a claim with Ford Corporate and requested they buy the vehicle back, because it meets the criteria and the elements under the Texas Lemon Law, regarding electrical and safety concerns. However, my claim was rejected. As of right now, there is no solution for this issue.

Receiving Front Camera Malfunction Service required warning. Also receiving pre-collision assist, adaptive cruise control and automatic emergency break system warnings. Other systems likely disabled. Found that there was a TSB issued for the same year but on the F-150. DTC's C1001:31, U3000:89, U3000:49. This issue is likely caused by faulty cable connections where condensation has caused corrosion making the system inoperable thus creating a major safety issue for owners. I took the Expedition to SawGrass Ford in Sunrise FL and they confirmed that the issue was due to the electronics/cables. The camera itself was not dirty or blocked. They charged me $250 for a diagnostic and then wanted to charge me $2500+. For the safety and security of all owners please investigate and hold FORD accountable for this.
