Tesla Model S proves troublesome for Consumer Reports

The Tesla Model S has turned into the breakthrough model that electric cars needed. Instead of looking like a futuristic jellybean whizzing by, the Tesla would still be incredibly attractive with a V8 stuffed under the hood. But beyond its appealing styling, the luxury sedan offers a realistic driving range, impressive performance and oft-praised driving dynamics. It's everything many drivers are looking for. However, as more long-term reviews come out, it's becoming clear that living with one of these wonder cars isn't without its fair share of problems.
A few weeks ago, Edmunds published its 17-month ownership experience with a Model S. It praised the experience being behind the wheel of the luxury sedan, at least when it was possible. Edmunds reported that it had to make seven unscheduled trips to the service bay and even left a writer by the side of the road once. The biggest issues included replacing the drive unit three times, needing a new main battery and numerous resets of the center screen.
Consumer Reports just wrote about its own driving impressions after 15,743 miles, and its experience with the Model S has hardly been a walk in the park, though not nearly as bad as Edmunds' rough time. The infotainment screen needed a hard reset once after blinking out, and one unscheduled service left the sedan in the shop for two days. There have been other, smaller issues too. In Tesla's favor, the repairs were done under warranty.

Tesla Model S vulnerable to hackers?

Next time you walk by a parked Tesla and its sunroof is opening and closing with nobody sitting inside or around it, you could be witnessing a hacker moment. For all of its strengths as a car, the Model S reportedly has a weak spot: the security of its API (application programming interface) authentication, according to an article in the O'Reilly Community by George Reese, executive director of cloud management at Dell. Tesla develops and uses its own API authentication protocols, which have made access to certain Model S functions too easy for hackers, Reese says - himself a Model S owner.
At question is the Tesla REST API, which is accessed via a web-based portal, usually by Model S owners with their iPhone or Android-based smartphone, to perform a variety of menial tasks and check the status of the car. The Tesla-registered e-mail and password of the car owner is used to access the API through a web portal, which creates a "token" that lasts for three months. During that period, owners access the Tesla REST API via the token without the use of their log-in information. Unfortunately, the tokens and their respective cars are stored on website databases that are all too easy to hack, Reese explains, and if a hacker gains access, "it has free access to all of that site's cars for up to three months with no ability for the owners to do anything about it." On top of that, there is no way to revoke access of a compromised application.
Reese says that "there's nothing in the API that (can? should?) result in an accident if someone malicious were to gain access." The API can check the car's battery charge, operate climate control, operate the sunroof, identify car location, honk the horn, open the charge port, and perform other similar operations. But, he cautions, "Perhaps the scariest bit is that the API could be used to track your every move."

And now for a different sort of Tesla Model S review...

Our friends at Kelley Blue Book have taken an unflinching look at the Tesla Model S in a new video. The crew originally planned to pack up and whip the electric sedan all the way to Las Vegas from Los Angeles, but got sidelined by a flat tire. The ensuing detour to a Tesla service center resulted in a day of hopping from charge point to charge point and a number of close calls on the range front. Confronted with cold temperatures, a desire to make time and some serious topography, the Model S pulled up short on projected range but never left the guys stranded.
The team eventually makes it to Vegas and discovers the aggravation of trying to charge the car with anything other than the company's supercharger stations. The return trip goes quite a bit better, however, and KBB starts to figure out what makes the Model S so special. We won't ruin the end for you. You can check out the full clip below.
