Electric Vehicles and Flooding: How Safe Are They?

Recent floods raised concerns about electric vehicles (EVs) in South Florida. Despite claims, EVs are vulnerable; water damage repairs vary.

Recent floods in South Florida left many cars stranded, including numerous electric vehicles (EVs). This occurrence raises concerns about the safety of EVs in such conditions.

Traditional gas engines, which rely on air and fuel, can be seriously damaged by water ingress. Electric vehicles, on the other hand, are designed with seals to protect their batteries and electronic systems. However, these seals can degrade over time, leading to potential leaks, according to Jonathan Sanchez, lead supervisor at EV Garage Miami.

The Cost of Water Damage

Sanchez, who has experience with both gas-powered and electric vehicles, stated that water damage repairs could be cheaper for EVs if you’re fortunate. Traditional combustion engines have complex parts that can take a considerable amount of time and money to repair, often costing upwards of $10,000.

In some cases, water-damaged EVs can be fixed by removing and drying the battery, similar to how one might handle a waterlogged cell phone. Sanchez estimates that this process would take about an hour and cost approximately $500 at his garage.

However, if water penetrates too far into the battery, it can result in catastrophic failure, leading to a hefty repair bill of around $18,000.

After the recent floods, several vehicles were brought into EV Garage Miami for repairs. Thankfully, none of them suffered catastrophic battery damage. Instead, the most common issues were panels falling off, water-damaged carpets, and torn bumper covers due to driving through heavy water.

Vehicle Water Resistance

Some companies, such as Tesla, claim their vehicles are more robust against water damage. Elon Musk, for example, stated that the Tesla Cybertruck should be able to briefly cross rivers and even seas that are not too choppy.

Despite these claims, even a Cybertruck was seen being towed out of South Florida floodwaters this week. According to the National Weather Service, six inches of water can reach the bottom of most passenger cars, and a foot of water can stall most vehicles, regardless of whether they are electric or not.

False Perceptions About EVs and Water Resistance

Brent Gruber of JD Power, a data analytics company, has sought to dispel the misconception that EVs can safely drive through floodwaters. The notion gained traction following a viral video showing a Tesla navigating a flooded street in San Diego.

Damaging to vehicles is almost inevitable when they are driven through deep, standing water. “I cringe when I see the videos because it damages the vehicle,” Gruber said.

Research conducted by the National Highway Traffic Safety Administration and the Idaho National Laboratory after Hurricane Ian in 2022 found that between 3,000 to 5,000 EVs were damaged. Among them were 600 total losses and about 36 that caught on fire. Salt or brackish water, which erodes cars, was the primary cause.

“EVs are designed to operate safely in the rain but they are not designed to be boats,” Gruber said, reiterating the importance of avoiding driving in flooded areas.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
