I own a 2018 Ford Expedition, and the factory-installed backup camera has progressively failed. Initially, the camera display was intermittent—sometimes showing the rear view and other times freezing or going black. The issue has now worsened to the point that the camera no longer turns on at all when the vehicle is placed in reverse. This failure presents a significant safety hazard, as the…

The failure pattern owners describe
Buyer takeaway: Two 2018 Expeditions caught fire under the hood due to electrical issues—one destroyed a vehicle during a dealer test drive, the other spontaneously on the highway. The electrical system is prone to persistent gremlins: backup cameras fail, infotainment screens go dark, batteries mysteriously drain, and multiple safety systems fault out intermittently while driving. Sunroof leaks are widespread despite technical service bulletins; transmission power loss on the highway has nearly caused collisions; and doors/locks don't work reliably. Pass on this model year unless independent inspection clears all electrical and powertrain systems thoroughly.
Owners report two catastrophic engine compartment fires: one started during a dealer test drive following repairs and destroyed the vehicle in 2-3 minutes with windows blown out; the other ignited spontaneously on the highway after the dashboard warned about low battery. Both were confirmed electrical fires.
Beyond the fires, the 2018 Expedition's electrical architecture is unreliable. Backup cameras fail intermittently then completely, infotainment screens won't power on, and multiple safety systems (cross-traffic alert, blind-spot monitoring, liftgate sensors) throw phantom faults while driving at highway speeds. Eight separate stranding events in the first eight months stem from the battery entering deep sleep mode unprovoked; dealers replaced the battery and ignition switch without solving the root cause. Engine stalling at red lights, transmission downshifts without warning during freeway driving (dropping speed from 70 to 40 mph), and running boards dropping unexpectedly when parked round out the electronic gremlins.
Water intrusion is widespread: sunroof seals fail at multiple points despite Ford technical service bulletins documenting the defect, and rear brake light housings fill with condensation that never dries, killing LEDs and dimming your brake lights to following traffic. Rear doors won't unlock properly, requiring repeated attempts. One vehicle experienced sudden movement while in Park, striking passengers at the doors. Dealers consistently claim they cannot replicate issues or find root causes, leaving owners stranded with inoperative vehicles, safety systems offline, and warranty denials citing normal dissipation.

Failure modes owners describe
Engine Fire - Spontaneous Ignition
Two separate incidents where the engine compartment caught fire, destroying the vehicle. One fire occurred during a test drive at the dealership following repair work; the other happened spontaneously on the highway after a low-battery warning on the instrument cluster. Both were confirmed as electrical fires by fire personnel. Owners report motor blocks melted, windows blown out, and total loss of vehicles.
When: One during test drive post-repair; one spontaneously while driving on freeway
Symptoms owners cite: Engine fire/spontaneous ignition under hood; Pre-fire dashboard warning about conserving battery; Engine smoking (pre-fire warning in one case); Complete vehicle loss, windows blown out
Repairs/costs cited: Not repaired; both vehicles were total losses
Recalls/TSBs owners mention: Ford has issued a recall settlement for 2021 Ford Expedition fires. Owner notes that similar fires reported on older Expedition models and F-150 trucks have not been recalled.
Sunroof Leaks and Bracket Failure
Multiple water intrusion points in the Vista Roof assembly, with broken brackets and inoperable sunroof mechanism. Water enters the cabin from several areas. Vehicle was sold with Ford Blue Warranty but warranty denied coverage despite documented TSBs addressing the defect.
When: Approximately 98,000 miles at purchase; issue developed shortly after purchase
Symptoms owners cite: Water leaking from multiple points across Vista Roof; Sunroof stuck and inoperable; Broken sunroof brackets; Water intrusion into cabin
Repairs/costs cited: Dealership advised complete sunroof assembly replacement required due to broken brackets; estimated cost not provided. Owner required to pay out-of-pocket as warranty denied coverage.
Recalls/TSBs owners mention: Ford issued Technical Service Bulletins (TSB 18-2374, TSB 19-2374, TSB 21-2292) but warranty denied coverage stating no assistance or goodwill coverage would be provided.
Transmission Downshift/Power Loss - Intermittent
Vehicle downshifts unexpectedly during highway driving, coasting, and acceleration, causing abrupt loss of power and inability to accelerate. Occurs approximately 20 times, with no diagnostic codes retrieved. Creates dangerous situations on freeways with near-miss rear-end collisions and traffic merge hazards. Recovery takes 10-15 seconds. Accompanied by loud clunking/dropping sound.
When: Intermittent during warranty; continues out-of-warranty
Symptoms owners cite: Sudden downshift while coasting at highway speeds; Unexpected downshift during acceleration attempts; Power loss dropping speed from 70 to 40 mph; Inability to accelerate/get into gear after downshift; Loud clunking or dropping sound prior to event; Check manual warning that appears then disappears
Repairs/costs cited: Taken to dealer and repair shop multiple times; issue cannot be replicated. No repair attempted. Now out-of-warranty.
Recalls/TSBs owners mention: No response documented; dealer unable to diagnose or repair.
Rear Brake Light Moisture and LED Failure
All rear brake lights contain persistent moisture/condensation that does not dissipate, with the upper (third) brake light most affected. Moisture accumulation leads to progressive LED failure; upper light now has fewer than 2 LEDs functioning, creating visibility hazard. Warranty denied coverage claiming moisture will dissipate on its own.
When: Issue present from purchase; LED failure progressing over time
Symptoms owners cite: Condensation in all rear brake lights; Upper brake light never fully dried; Progressive LED failure in upper brake light; Reduced brake light visibility to following vehicles
Repairs/costs cited: Dealer quote provided for light replacement; cost not specified. Owner did not proceed due to warranty denial.
Recalls/TSBs owners mention: Warranty explicitly denied, with dealer stating Ford does not cover moisture within lights as it will dissipate over time. This contradicted the owner's documented experience of persistent moisture.
Battery Deep Sleep/Stranding Events
Vehicle enters deep sleep mode unexpectedly, leaving driver stranded with dead battery unable to start. Eight separate stranding incidents occurred within first eight months of ownership (June 2018 to February 2019). Vehicle required jump-starts from larger vehicles to restart; small car jumps were ineffective. Dealer service unable to diagnose root cause despite multiple visits.
When: Within first 8 months: 06/11/18, 08/09/18, 08/19/18, 08/22/18 (twice), 10/13/18, 11/11/18, 02/06/19
Symptoms owners cite: Vehicle enters deep sleep mode without warning; Battery dead; unable to start engine; Requires jump-start from large vehicle to restart; Small vehicle jump-starts ineffective; Dashboard technology appears unresponsive
Repairs/costs cited: Dealership proposed battery replacement; owner skeptical this will resolve the underlying issue. No other repairs attempted despite multiple diagnostic visits.
Recalls/TSBs owners mention: Ford initially stated nothing was wrong after first incident. Dealer unable to find issues during subsequent visits. Ford denied replacement request.
Backup Camera Failure - Intermittent then Complete
Factory-installed backup camera initially intermittent (freezing, going black, not displaying), then progressed to complete failure. Camera will not turn on when vehicle is placed in reverse. Vehicle is non-compliant with FMVSS No. 111 (rear visibility requirement for vehicles post-May 2018). Represents safety hazard in large SUV with limited rear visibility.
When: Progressive failure; initial intermittent issues then complete failure
Symptoms owners cite: Camera display intermittent, freezing, or black screen; Camera no longer turns on in reverse; Lost rear visibility safety feature; Vehicle non-compliant with FMVSS 111
Repairs/costs cited: No repair attempted; issue documented as safety defect
Recalls/TSBs owners mention: Not documented in complaint

When: Identified at unspecified mileage
Symptoms owners cite: Radio/infotainment screen does not turn on; Backup camera cannot display; No vehicle damage present
Repairs/costs cited: No repair attempted
Recalls/TSBs owners mention: Not documented
Failure to Start - Multiple Causes
Vehicle failed to start on three separate occasions within first two months of ownership. First incident required 30-minute wait then started; second occurrence would not start despite adequate battery power, jump-starting ineffective, required towing; third incident occurred after vehicle sat for couple of hours. Multiple repair attempts included battery replacement, ignition switch replacement, and starter replacement, suggesting root cause was not properly identified.
When: Sept 4 (purchase, first episode), Sept 8 (second episode), Nov 19 (third episode)
Symptoms owners cite: Vehicle will not start; Adequate battery power present; Jump-starting ineffective (first occurrence); Vehicle won't stay in neutral for towing, returns to Park; Multiple start failures within short timeframe
Repairs/costs cited: Battery replaced, ignition switch replaced, starter replaced. Final diagnosis reportedly resolved the issue.
Recalls/TSBs owners mention: Dealership performed repairs under warranty and claimed issue resolved after starter replacement.
Retractable Running Board Malfunction
Passenger-side retractable/automatic running board intermittently drops down when vehicle is parked and stationary for 2-3 hours. Board retracts when vehicle is restarted and doors operated, but recurring pattern continues. Running board motor on passenger side was replaced in fall 2019, but problem recurred in March 2020, suggesting underlying electrical or mechanical issue.
When: Fall 2019 repair; recurred March 2020
Symptoms owners cite: Running board drops when vehicle at rest for 2-3 hours; Board retracts most of the time after restart and door operation; Recurring pattern after repair
