BMW tops Consumer Reports 2023 Brand Report Card

Feels like we wrote about Consumer Reports' 2022 Brand Report Car and 10 Top Picks a few weeks ago, but it was last April. So the mag is back with a ranked roster of 32 brands and 10 vehicles in four categories for your debating pleasure. Starting with the brands, last year's top three were Subaru, Mazda and BMW. This year, the Munich crew climbed two spots to win the prize thanks to "Superb road test scores and solid results in CR’s reliability and owner satisfaction surveys." Subaru narrowly fell to second, maintaining its four-year run in the top three. Mini, eighth last year, jumped five spots to get the last step on the podium. The rest of the top 10 were Lexus (up one spot from last year), Honda (down one spot from last year), Toyota (up three), Genesis (up 12), Mazda (down six), Audi (down three) and Kia (up eight). The magazine and testing outfit says its Brand Report Card "[reveals] which automakers are producing the most well-performing, safe, and reliable vehicles based on CRÂ’s independent testing and member surveys," and that "Brands that rise to the top tend to have the most consistent performance across their model lineups." Last year's top 10 had six automakers from Japan, three from Germany (giving Mini credit for England), none from the U.S. or South Korea, and five luxury brands. This year's list counts five makes from Japan, two from Germany because Porsche fell out of the top ten, two from South Korea, still none from the U.S., and four luxury brands. Buick again ranked as the best domestic, dropping to 12th after being 11th last year. The big mover was Lincoln, its 10-place jump up to 16th attributed to better reliability from the Corsair and Nautilus. Tesla's improved overall reliability saw it climb six spots to 17th. Dodge climbed one spot to 15th. Jeep got out of the penalty box in last to come second-to-last. Land Rover fell three places into the penalty spot.  CR's top 10 vehicle models The 10 Top Picks list is practically a new list. Only two holdovers made it to 2023, those being the Subaru Forester and Kia Telluride.

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."

Investigators Find No Defect Trend With Tesla Motors' Model S

Federal safety investigators said Friday they have found no apparent defect trends in the Tesla Model S, an electric luxury car that has its share of fans and critics. The National Highway Traffic Safety Administration closed a four-month investigation into whether the car's batteries were at heightened risk for underbody strikes and subsequent fires. Even though no defect trend was found, Tesla Motors said in a written statement it would further protect the bottom of its cars with a reinforced underbody shield. The California-based automaker started adding the shields on March 6 and will retrofit older models free of charge. It will also increase the ground clearance of new cars. "This fix should eliminate the potential of a battery-pack fire under all but the most extreme circumstances," said Karl Brauer, a senior analyst at Kelley Blue Book. Although there are more than 194,000 car fires in the United States every year, NHTSA investigators began a preliminary investigation into potential trouble on Nov. 15, 2013 following two Model S fires, one in Tennessee and one in Washington. No one was injured or killed in either fire. Roadway debris punctured the battery pack near the front of the compartments in both cases, damaging the batteries' lithium ion cells that then began "thermal runaway" events. The opposite ends of the debris had dug into the pavement and jutted upward. Tesla called this a "piking effect." The company said it has conducted 152 vehicle level tests, and that the new shields prevented any damage or penetration of the new shields. The first is a rounded, hollow aluminum bar that's followed by a titanium plate. The third layer of protection is made of solid aluminum. (There's video of the new plates in action on the Tesla Motors website). "We have tried every worst-case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event," Tesla Motors founder Elon Musk wrote on the company's blog," essentially equivalent to driving a car at highway speed, into a steel spear braced on the tarmac." Approximately 15,805 vehicles are eligible for the upgrades, which NHTSA says should reduce the frequency of underbody strikes and subsequent fire risks. But the agency did note that the closing of the investigation did not necessarily constitute a finding that a defect does not exist. "The agency reserves the right to take further action if warranted by new circumstances," it said.
