We all know electric cars are more reliable than gas, but which are the most reliable of the electric bunch?
You may find it to be the proverbial brave new world if you’re in the market for your first electric vehicle. Though the concept of driving an auto that plugs into a wall socket might seem futuristic, the underlying technology has been around since the mid 19th Century. Advancements in battery technology enable the latest EVs to run for as many as 300 miles or more on a charge.
But as with any automotive purchase, EV shoppers may foster concerns about a given model’s long-term reliability. At least theoretically, electric cars should prove to be less problematic than their gasoline-powered counterparts. Electric motors are inherently less complex pieces of machinery than are gasoline engines. EV transmissions utilize only a single forward gear instead of as many as 10 in a conventional automatic transmission. Plus, EVs require less maintenance by sidestepping over two dozen components – including spark plugs, drive belts, the oil pump, and water pump, among others – that would at some point need replacing.
On the downside, a vehicle’s battery pack will eventually degrade. Having the battery swapped out can be an expensive affair; a replacement battery for the Nissan Leaf reportedly costs $5,500. Fortunately, federal law mandates automakers guarantee their EV batteries for at least 8 years or 100,000 miles.
For its part, Consumer Reports says EV reliability has been stellar thus far. Among newer models, CR says the Chevrolet Bolt EV is expected to be “very reliable” after just debuting for the 2017 model year. What’s more, CR says if they’re properly maintained any EV can easily keep running for 200,000 miles or more.
However, as we all know, some cars ultimately prove to be more trouble than others over the long haul. Unfortunately, finding information on a given EV’s long-term reliability can be difficult. Ratings from the two main sources we consulted, Consumer Reports and JD Power, tend to be limited to the segment’s most popular models. That’s due to a lack of owner-survey feedback on EVs having relatively miniscule sales, especially those that aren’t offered nationwide.
We’re featuring the five nationally available electric cars from the 2018 model year that our sources project will be the most dependable over time.
