A Ford F-150 Lightning owner asking about flooded streets around Newport Beach, California, briefly concluded that his truck could handle two to three feet of water after watching a video shared in an owners’ forum. Other members challenged that reading, and he later acknowledged the warnings. He never reported attempting the crossing.
The October 27 discussion began with Dspade asking whether coastal flooding during king tides was safe to drive through. In a separate public post earlier that month, the same member identified his truck as a 2025 Lightning Flash. His question concerned the Newport Beach peninsula, where saltwater made the advice particularly consequential.
A Video Answered More Than It Could Prove
One member supplied a Lightning flood-driving video while also repeating the usual advice to avoid flooded roads. Dspade took the footage as reassurance that two to three feet might be manageable and said he would proceed cautiously.
Other replies emphasized saltwater exposure
Other replies emphasized saltwater exposure. Some discussed wheel-hub height; others referred to videos and older reviews mentioning deeper crossings. Several became insulting. Eventually, the owner complained about the contradictory advice and wrote,
“Ok I got it guys. Don’t drive in water, period!”
His question was worth asking. The useful response requires separating a vehicle’s documented operating limits from somebody else’s successful crossing. A clip showing a truck emerge from water does not establish the depth beneath it, the condition of its seals, or what happened afterward.
Even a dedicated water-driving feature has limits. The separate Cybertruck lake incident involved a driver reportedly testing Wade Mode before the vehicle became disabled. That truck’s equipment and circumstances cannot establish a safe depth for a Lightning.
Newport Beach Was Already Moving Vehicles Out of Danger
The concern had a real local setting
The concern had a real local setting. Newport Beach Police’s October 27 update reported an 8.4-foot high tide and warned about flooding around the Balboa Peninsula and Newport Harbor. That was a tide-height measurement, not eight feet of water over a street.
The city extended a suspension of parking enforcement through October 28 at 6 p.m., allowing residents to move vehicles to higher ground or public parking lots. Crews were operating pumps, and officials arranged a temporary closure beneath the Newport Boulevard Bridge to reduce boat wakes during the following morning’s high tide.
Those measures gave drivers a practical alternative to testing their trucks. Moving a vehicle before water rises preserves access and avoids discovering the depth from inside it. A flooded route can conceal debris, a damaged surface, or deeper sections that are invisible from the approach.
Ford’s Limit Is the Bottom of the Wheel Hubs
Ford’s 2025 Lightning water-wading instructions tell drivers never
Ford’s 2025 Lightning water-wading instructions tell drivers never to enter water above the bottom of the wheel hubs. They also warn against deep, fast-flowing water and require checking the depth and watching for submerged obstacles. That is substantially narrower than the three-foot interpretation circulating in the discussion. Ford also calls for checking the brakes, horn, lights, and steering after leaving water, once safe.
The adjoining guidance warns that water can enter electrical components, the motor, drivetrain, or cabin, and says the vehicle warranty excludes water damage. Its controlled-crossing instructions should not be read as permission to enter an unfamiliar flooded street, particularly one affected by the ocean.
The question extends beyond whether the truck keeps moving. An earlier Bolt battery-damage account involved an owner reporting a punctured pack and an expensive replacement estimate. Diagnosed damage matters; an uneventful-looking drive cannot establish the condition of components hidden underneath.
Likewise, a low-mileage F-150 returned over corrosion illustrates why
Likewise, a low-mileage F-150 returned over corrosion illustrates why the underside deserves inspection. That account did not establish flooding as its cause. Rust, water intrusion, and battery damage each require evidence rather than a diagnosis from a photograph or an odometer reading.
After Flood Exposure, Get Qualified Help
NHTSA’s teardown study of 10 flood-damaged EVs recovered after Hurricane Ian offers a useful caution about appearances. Nine retained a high state of charge after water exposure and 10 months in storage. Investigators identified saltwater entry paths into the battery packs, although none of the vehicles had enough infiltration to trigger a thermal event.
The small sample cannot establish a fire rate or a safe crossing depth. It does show that a flood-damaged EV can retain substantial stored energy long after the water recedes. A quiet vehicle sitting in a driveway may still require electrical precautions during inspection and recovery.
NHTSA warns that flood-damaged electric vehicles can present
NHTSA warns that flood-damaged electric vehicles can present high-voltage shock and fire hazards. It advises owners who suspect battery damage to contact their dealer or emergency services, and says a damaged lithium-ion vehicle should not be stored in a garage or within 50 feet of structures, other vehicles, or combustible materials.
A driver should not approach or move a potentially hazardous vehicle merely to meet that spacing. Keep away and tell responders or the recovery operator that an EV may have been exposed to saltwater. If smoke, unusual heat, hissing, or fire develops, move away and call 911.
For a truck that has been exposed, professional assessment comes before charging or returning it to work. The Lightning’s ability to supply backup power during an outage can be valuable, as a Kauai bakery operator reported when keeping refrigeration running. That use assumes a vehicle is safe to operate; it does not override flood-damage precautions.
