The influential Consumer Reports magazine has again downgraded Tesla’s Model S sedan, this time due to a lack of an important safety feature that was supposed to be included as standard equipment.
CR has downgraded Tesla products on several occasions, though past moves focused on quality concerns. This time, the magazine said, the Model S produced over the last six months did not have a working emergency auto-braking, or AEB, system, apparently because of a problem with software that was supposed to control an updated version of the AEB hardware introduced in October 2016.
It’s the latest in a series of problems involving Tesla’s high-tech safety technology. Last week, Tesla was hit with a lawsuit claiming that its optional, semi-autonomous Autopilot system is “unusable and demonstrably dangerous.” Days later, the battery-carmaker announced a recall covering a parking brake problem affecting 53,000 vehicles.
