NEWS: Porsche is recalling certain 2015 Macan vehicles; SERVICE BRAKES, HYDRAULIC Report Receipt Date: AUG 01, 2014 NHTSA Campaign Number: 14V470000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 7
SEPT 2014 -- Porsche Cars North America, Inc. (Porsche) is recalling certain model year 2015 Macan vehicles. During manufacturing, the brake booster may have been damaged during installation. If the brake booster was damaged during installation, the vacuum in the brake booster may drop when the brakes are actuated, resulting in a reduced brake force boost, increasing the risk of a crash. Porsche will notify owners, and dealers will inspect and replace the brake booster, as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Porsche's number for this recall is AE02. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Thanks for sharing, glad you got stopped without more of a problem.
Am not a Porsche mechanic but have worked on a few cars. IMO, based on information provided your problem is electrical in nature, a sensor / loose connection letting water in. Boosters are mechanical tend not to fail intermittently. When a booster fails your brakes should still work, but should feel like non-power brakes of yesteryear, that isn't what you describe. The Lane Change Assist icon is also lighted on the fault screen, hmmm. Something going on in the electronics is completely stopping brake function.
You stated that you stayed off the freeway due to braking concerns... Were those concerns car-related..? And if so, what kind of braking problems were you having before to have those concerns?

All of the sudden, brakes failed, brake pedal would not go down and I got a fault notice that I will try to upload stating brake fluid was low (it wasn’t) and, shockingly, “Driving permitted.”
I stayed off the freeway because it was raining and I had lost the brakes previously in the rain on the freeway. The dealer said it was a fluke and gave me the car back a month earlier. Ultimately, I think they blamed it on some kind of pinhole leak in a hoseThey replaced the hose and I haven’t had trouble since.
