Fortunately, only a handful of vehicles are affected in the United States.
With performance as prodigious as that which (at least certain versions of) the Porsche Panamera are capable, drivers count on the brakes to be working, and working well. But Zuffenhausen's uncovered problems with the stoppers on some of its hybrid four-doors and wagons, so it's had to recall a handful of them in the United States.
According to the the recall notice issued by the National Highway Traffic Safety Administration, the problem comes down to the front-end brake lines, which "may corrode over time" and (suffice it to say) "may affect the front braking performance."
Fortunately the issue is limited to just 112 vehicles in the US – all of them 2018 models, including the standard, long-wheelbase Executive, and extended-roof Sport Turismo versions of the Panamaera 4 E-Hybrid and Panamera Turbo S E-Hybrid. Fixing the problem will entail replacing the rusty brake lines and any other brake components that may have been damaged as a result. The recall campaign is set to kick off on January 27.
The gasoline-electric versions of the closest thing Porsche makes to a conventional sedan or station wagon, both E-Hybrid versions of the Panamera employ a 100-kW electric motor.
The Panamera 4 E-Hybrid pairs it to 2.9-liter twin-turbo V6 for a combined 456 horsepower and 516 lb-ft of torque, while the Turbo S E-Hybrid packs a 4.0-liter twin-turbo V8 for a total of 671 hp and 627 lb-ft.
That's enough to send the V6 model scurrying to 60 in 4.4-4.6 seconds (depending on the version) before topping out at 172 mph. Given enough road, the V8 version will hit 192 mph, passing 60 mph in as little as 3.4 seconds along the way. The EPA rates them at the equivalent of between 46 and 49 miles per gallon on the combined cycle.
