2021 PORSCHE MACAN Service Brakes Problems

On November 12, 2025 the transmission, power train, and/or other components on my Porsche Macan S failed. My Macan was parked (gear selector in "Park") on a level surface, the ignition turned off and the key removed from the ignition when it was tapped from behind by another vehicle that was exiting a residential garage.

I wrote earlier today but now I found out the Porsche Cayenne and Porsche 911 all have safety feature lacking in the new macan - if u try to reverse with the engine off a message will come on that says to turn on the engine and engage the gear. The macan can reverse with no engine on and then you have no brakes and no power steering . There is a small window of one attempt according to Porsche to use the brakes but you would need to be a strong large man to accomplish the amount of effort required per the dealership - this was not reviewed at the time of purchase .. it seems this safety feature has been around for at least a decade and I am not sure why the macan hasn’t upgraded this important feature or let the customers know in advance We have...
