After transitioning from i35 south, to Highway 183 towards Austin-Bergstrom International Airport, the auto-pilot (Ford Blue Cruse) fails, the speedometer fails, the battery level indicator fails, the instrument cluster fails, cruse control picks a random speed and struggles to keep it, lane keep assist is erratic at best. This occurs every time, and in both directions, I take my vehicle on that…

The failure pattern owners describe
The dominant issue is failure of the high voltage battery junction box (HVBJB) contactor assembly. Owners describe sudden loss of motive power at highway speeds—one lost all propulsion while passing traffic, another experienced complete vehicle shutdown on an exit ramp. The car locks into park, refuses to shift to neutral, and kills power steering and brakes. Owners point to Ford recall 22s41 (NHTSA 22V412000) as a software-only fix that limits voltage to prevent future damage but leaves already-damaged contactors in place. Some owners report replacement HVBJBs arrived with identical defective design. Redesigned components exist and have been used for warranty repairs, but aren't required under the recall.
Secondary failures include repeated rotor warping—one owner replaced seven pairs between 12,000 and 36,000 miles with violent brake vibrations, while Ford called it normal wear. Another owner reports Blue Cruise, speedometer, battery indicator, and instrument cluster all failing simultaneously on a specific highway segment, repeating every trip. A third describes steering oscillation and erratic behavior when autopilot engages. One complaint documented a forced software update that locked the car during active highway driving instead of using the scheduled 1 AM WiFi window.
These are unverified consumer allegations of serious safety failures—sudden power loss, loss of steering and brakes, and brake pulsation—concentrated in the charging and power delivery systems.
Failure modes owners describe
High Voltage Battery Junction Box (HVBJB) contactor failure
The HVBJB subassembly contains under-designed main contactors that fail under normal charging and driving conditions. Internal contactor damage is not visible externally and only shows warning messages after damage occurs. Failures can result in sudden loss of propulsion power at highway speed, loss of power steering and power brakes, and failure to charge the 12V battery, leading to cascading electrical system failures.
When: Normal charging and driving conditions; internal damage can accumulate over 2+ years of use before manifesting as a safety event
Symptoms owners cite: Sudden loss of propulsion power at highway speeds; Loss of power steering; Loss of power brakes; Loss of 12V system charging; Vehicle lock-up and forced entry into park, unable to shift to neutral; Failure to start; Red ring indicator around charging port after DC fast charging; Complete vehicle shutdown with 'Stop safely now' warnings and battery warning symbols despite 100% charge
Repairs/costs cited: Ford offered software-only update (recall 22s41 / NHTSA Campaign 22V412000) that limits voltage to prevent future damage but does not address existing internal contactor damage. Redesigned HVBJB subassemblies with 'beefier' components are available and have been used for warranty repairs, but recall does not require replacement of known-to-fail original units. Some owners reported replacement units received were the same defective design. Dealership service requires specialized equipment and training.
Recalls/TSBs owners mention: Ford recall 22s41 (NHTSA Campaign 22V412000) issued as software-only update. Revised NHTSA Recall 23V687 issued but not sent to all affected owners. Ford has refused to acknowledge coverage for some vehicles where the defective part was already replaced with identical defective component.
Excessive rotor warping and brake pulsation
Rotors warp and require replacement at frequent intervals. When braking after exceeding 50 mph, owners report violent steering wheel vibrations between 43–35 mph. Pattern suggests systemic design or manufacturing defect rather than normal wear.
When: First rotor replacement between 12,000–36,000 miles; occurs approximately every 3,000 miles thereafter
Symptoms owners cite: Violent steering wheel vibrations during normal braking after highway speeds; Rotor warping requiring repeated replacement; Safety issue occurring on regular driving intervals
Repairs/costs cited: 7 pairs of rotors replaced between 12,000 and 36,000 miles. Owner has service records and video documentation. Ford classified as 'normal wear and tear' and denied coverage after 36,000 miles, despite pattern differing from peer vehicles in same geographic area.
Recalls/TSBs owners mention: Ford denies warranty coverage after 36,000 miles, classifying repeated rotor failures as normal wear and tear despite service documentation showing 7 replacements in 24,000 miles.
Instrument cluster and autopilot failures at specific highway location
Multiple systems fail simultaneously when vehicle travels on a specific highway segment. Failures include autopilot (Blue Cruise), speedometer, battery level indicator, instrument cluster, cruise control, and lane keep assist. Failures are repeatable in both directions on that highway.
When: Transition from I35 South to Highway 183 towards Austin-Bergstrom International Airport; occurs every time on that route
Symptoms owners cite: Blue Cruise autopilot disables; Speedometer fails; Battery level indicator fails; Instrument cluster fails; Cruise control selects random speed and struggles to maintain it; Lane keep assist behaves erratically
Repairs/costs cited: Owner recorded video documentation of failures and offered it to Ford. Ford recommended filing complaint with NHTSA.
Recalls/TSBs owners mention: Ford recommended NHTSA complaint filing.
Loss of propulsion power during highway passing maneuver
Vehicle suddenly lost all motive power and began shutting down while owner was legally passing another vehicle on a 2-lane highway at over 50 mph, with oncoming traffic present. Owner was forced to pull to roadside in hazardous conditions.
When: During highway passing maneuver at 50+ mph
Symptoms owners cite: Complete loss of motive power; Vehicle shutdown during highway driving; No power available to reach safe location
Steering oscillation side-to-side
Steering wheel oscillates rapidly right and left during normal driving. Owner references this as matching a 2022 recall description pattern.
When: During normal driving
Symptoms owners cite: Steering oscillates right and left
Blue Cruise autopilot erratic behavior potentially linked to side mirror camera failure
Semi-autonomous Blue Cruise engagement produces erratic vehicle behavior. Fault may originate in side view mirror camera modules based on owner assessment.
When: When Blue Cruise engaged
Symptoms owners cite: Erratic behavior when semi-autonomous Blue Cruise is engaged
Forced software update while driving at highway speed
Ford Pass app initiated a mandatory software update while vehicle was actively driving on a 4-lane highway at speed. The app message stated the vehicle would be locked and unusable during the update. Vehicle was connected to home WiFi where the update could have been scheduled for the programmed 1 AM off-peak time, but the update was forced during active highway driving instead.
When: During highway driving on I-12 in Mandeville, Louisiana; vehicle had 13k miles and was at 100% battery charge
Symptoms owners cite: 'Stop safely now' warning message displayed; Vehicle powered down within 3 seconds of warning; Multiple warning symbols appeared (battery warning despite 100% charge, turtle mode); Vehicle locked into park and would not move; Vehicle would not shift to neutral; Vehicle locked up on busy highway exit ramp creating dangerous traffic hazard
Repairs/costs cited: Vehicle had to be towed by roadside assistance and DOTD tow truck to Ford dealer. Ford Pass app message confirmed forced software update was the cause.
Recalls/TSBs owners mention: Ford executed forced software update via Ford Pass app during active highway driving rather than utilizing scheduled off-peak (1 AM) WiFi update window that was available.
