2015 Porsche Macan: Front Parking Sensors Freak Out Even in Reverse
April 21, 2015
Allow me to present a scenario. You jump into the 2015 Porsche Macan S. It is, per a perfectly common scenario, parked in a busy lot head-first against a wall. You check behind you like a responsible driver, looking for cross-traffic or pedestrians. There's nothing, so you put the car in reverse and prepare to move, noting in the rearview camera that there is still nothing behind you.
And yet, the Macan starts beeping at you as if you're about to run over something. What in the world?
After some confusion, you realize the rear parking sensors are not picking up a child, lawnmower or, I suppose, a woodland creature small enough to elude your eyes and those of the camera, but big enough for the rear sonar to pick up. No, the perimeter beeping is coming from the FRONT parking sensors detecting the wall in front of you. You're in reverse and the car is telling you there is something in front of you.
No kidding, thanks car.
How, in any way, is that helpful? By definition, if the car is in reverse, there's no way you can run into whatever is ahead. And since the rearview camera is on, the usual front perimeter display (pictured) doesn't come up telling you from what direction the beeping originates.
Now once you know about this, you can be prepared for the front sensor false alarm. But what if there is, in fact, something behind you and you've acclimated to ignoring the parking sensor that cried wall? Not good.
