"Maybe somebody wants to buy a...

Back in 2014, Tesla had a spate of problems with the drive units in early-production versions of its Model S electric sedan. (The drive unit is essentially the car’s power train: electric motor, inverter, and gear box.) High-profile multiple failures occurred in long-term test cars driven by...

In designing, testing, and producing the Nissan Leaf, the first modern electric car sold in volume, Nissan made a design decision that some other companies didn't. It chose not to build an active thermal-conditioning system (otherwise known as cooling) into its battery pack. Instead, it relies on...

Being a pioneer isn't easy. When you're pioneering new automotive technology, it can be challenging and sometimes costly. Just ask anyone who owned an early turbocharged sport sedan, for instance. That also applies, in some cases, to some of the first modern electric cars, and in particular the...

It's one of the most frequently asked questions by anyone hearing about a modern electric car: do I have to replace the battery? With 15 years of experience in mobile phones and more than that with laptop computers, most buyers know that lithium-ion batteries lose capacity over time. Replacing...

Tesla spends more on warranty costs than larger established carmakers.

Our recent article on the reliability implications of a Plug-In America survey of early Tesla Model S owners was met with skepticism from the company's supporters, and support from its skeptics.

One of the coolest things about owning a Tesla Model S for almost three years now has been the service. When first revealed back in the spring of 2013—a few months after I had taken delivery of my car—the Tesla service model sounded almost too good to be true. If a problem occurred, CEO...

I've had my 2013 Tesla Model S for two and a half years now, and I've reported on the entire process, from ordering through delivery. After an update on my battery capacity--which lost slightly more than average, but not worrisomely so--it's time for a roundup of other items I've faced as I reach...

The odometer on my 2013 Tesla Model S ticked over 49,000 miles yesterday. That means I’ll soon be facing a big financial decision: whether or not to buy Tesla’s extended warranty, or as they call it, extended service agreement (ESA). The car’s standard bumper-to-bumper warranty is...

Nissan and Leaf owners appear to have reached a final settlement in a lawsuit filed almost three years ago.

It was a car company's worst public-relations nightmare. Edmunds.com, the widely-read automotive website, bought a Tesla Model S for long-term testing in February 2013. After nine months and 11,000 miles, the car developed an ominous grinding noise under acceleration and deceleration. Under...

Three and a half years after the first Nissan Leaf went on sale, Nissan has announced the cost of a replacement lithium-ion battery pack for its electric car. It's a surprisingly low $5,499 (after a $1,000 credit for turning in the old pack, which is required), plus installation fees and tax. The...

Electric cars have been on sale almost three years now, which means that some of them are starting to show up on used-car lots. To alleviate concern over the unknown future life of a used electric car, Nissan has now added its Leaf to the company's Certified Pre-Owned Vehicles program. Starting...

To allay fears about loss of capacity in its Leaf electric-car battery packs, Nissan announced today that it would offer what amounts to a battery leasing program after the pack goes out of warranty. The cost of ensuring minimum capacity will be $100 a month. The company now warranties the Leaf...

There's nothing like a bargain price on a brand-new car. And since Suzuki has announced that it'll stop selling cars in the U.S., there are bargains galore on new Suzuki models. But is buying a brand-new car from a departing manufacturer a good deal? That depends on how the carmaker exits; unlike...

One big advantage of electric cars is reduced maintenance. With no internal combustion engine, there is no oil to change, no exhaust system, no transmission, no myriad of moving parts to break or wear out, and no air or fuel filters to clog up. With regenerative braking, brake pads last virtually...
