Trace water accumulation routing from clogged/faulty drain plug to corroded DCN wiring connector during rainfall. Due to manufacturing design of '23 Ford F150 model windshield drain cowls, minor debris allowed for water to backflow into the Data Communication Network (DCN) wiring harness and Body Control Module (BCM) connectors, interior electrical components, and interior of the cab wetting the upholstery and flooring within the front passenger side of truck. Driver experienced electrical black outs within the dash and center screens, lighting failures, and multiple system alert misfires while driving the vehicle. Alerts consistently glitching on the dash screen included: Service Vehicle Soon, Pre-Collision Assist Not Available, Service Advance Trac, Rear Belt Monitor Fault Service Required. The issues were reported to Ford, whose representatives noted the history behind water damages associated with cowl/drain designs, but confirmed the issue has not been formalized for recall. This known issue presents buyers with financial and physical safety risks, known by Ford, and places full responsibility for poor engineering on new owners. The vehicle is currently at the dealership for repairs and parts replacement. All at the owners expense.

Driving on two lane road, approximatly 45-55 mph, collision warning on dash and audiable message to avoid impending accident. There was no obstruction in the road. Has happened two times in the past 4 months. Once in daylight with clear weather, once nighttime and light rain. Both times temperature was 60-70 deg F. Concerned it could also apply the brakes accourding to Fords information. I have not had the problem diagnosed since it happens so infrequently.

1. Vehicle sat in a storage unit for 2 weeks. Battery registered adequate voltage when picking up vehicle 2. Started vehicle, engaged 4 Auto due to rain 3. Drove 16 miles in light to moderate rain at speeds of 30-60MPH 4. Made multiple stops at stoplight in town. When waiting at a red light, my foot was on the brake pedal for about 20 seconds, the pedal then jolted up a small amount. The dash immediately displayed several warning lights and messages: Antilock Brake Fault, Antilock Brake System Fault, Powertrain Malfunction/Reduced Power Fault, Electronic Parking Brake Fault, Hill Start Assist Fault, Precollision Assist Fault, Service Advance Trac Warning, Advanced Front Lighting Features Fault. 5. The light turned green and I proceed to the next light to turn off the main road and park in a neighborhood to call a tow truck. 6. In the process of slowing down for the turn, I applied pressure to the brake pedal, and it went to the floor with no resistance. Brakes were 95% gone. 7. Luckily there were no cars or pedestrians in front of me and I was moving under 30 MPH. This could have been CATASTROPHIC! I was able to use the transmission to downshift to slow the truck down. I was also able to apply extreme pressure to the brake pedal to barely slow the truck. When pressing hard on the brake pedal, I could here one or both of the rear tires sporadically screech, as if they locked up a small amount. 8. Finally was able to pull into a neighborhood and call a tow truck to bring truck to dealership. 9. When turning vehicle on to load onto tow truck. The vehicle started as no normal, with no warning lights and normal brake operation. Awaiting further diagnosis from dealer. 10. I have lost all trust in this vehicle if the brake sporadically give out without warning. Luckily this did not happen while going 80MPH on the highway and needing to make an emergency stop. Or while offroading on a shelf road with a 100 foot cliff on the side. Easily could be dead due to this failure.

Adaptive cruise control applies brakes at varied levels from light to full stop when passing vehicles on the left in an open highway setting when no vehicle is present ahead. Speed range is approx 65-75mph. Other conditions are Interstate highway open road, sunny to partly cloudy, and problem occurs when passing and a longer vehicle (CL8 or other vehicle with trailer is present on the right), no other unusual or notable conditions can be remembered at this time. Other vehicles following in trail were often surprised and required immediate throttle engagement to prevent collision from following vehicles. Not all unexpected brake events produced a warning, however it appears that full brake events a pre-collision warning did appear. 3 attempts were made but dealer was not able (authorized by OEM) to perform extended drive cycles. On 4th attempt claim was stored code was found and multiple components were replaced. However, problem reoccurred in a subsequent highway trip, and there was a clear degradation of the LKA accuracy, as the LKA would no longer keep lane center and would not correct of provide departure warning until on top of after crossing lane line markings. Additionally "hands on wheel" warning would appear even though hands were on the steering wheel at the time. The vehicle is now at the dealer for the 5th attempt at diagnosis and repair. The dealer and OEM claim that installing a data logger is not possible, which I find difficult to agree with as there are clear parameters to measure and tripper a recorded event.

My 2021 Ford F-150 intermittently displays the warning message “Reverse Brake Assist Not Available – See Manual” when the vehicle is placed in reverse. When this message appears, the reverse brake assist / parking collision warning feature is not available, which may reduce safety while backing up. The vehicle was inspected by a Ford dealership. The dealership confirmed DTC U3000:49 in the IPMA module and identified Ford TSB 23-2040 as applicable to the concern. The dealer stated that the repair requires an IPMA software/module update and calibration. The quoted repair cost was approximately $1,100. This appears to be a software/programming-related condition affecting a driver assistance and brake-related safety feature, not normal wear and tear or a failed mechanical component. The warning is intermittent, but it has appeared multiple times. The vehicle is available for inspection upon request. No crash, injury, or fire has occurred. Ford Customer Support was contacted and case number XXX was opened. Ford advised that no active warranty, recall, or customer satisfaction program currently provides repair cost coverage, and that because this involves Reverse Brake Assist, I may choose to file a safety concern report with the federal safety agency.

While driving my 2021 Ford F-150 PowerBoost, the vehicle issued a pre-collision warning followed immediately by a restraint system warning. The airbag then deployed without any collision or impact. There was no crash, obstacle, or reason for deployment. The airbag deployment shattered the windshield and caused interior damage. This appears to be a false activation of the pre-collision system and unintended airbag deployment, creating a serious safety hazard. This could easily result in injury or loss of vehicle control. The vehicle needs to be investigated for a potential defect in the airbag system, sensors, or pre-collision assist system.
