2021 Porsche Macan Reliability Score & Common Problems

My daughter accidentally tried to reverse in auxiliary mode- she had the radio on and did not realize the engine was not on The car went into reverse and she had no brakes or steering to stop the car Mercedes - BMW- Range Roger - Tesla - we have checked these cars and it isn’t possible to do this scenario in those cars Porsche said the car is fine and if she was 6’3” and weighed 250 it would be difficult but possible to apply enough pressure to the brakes - she weighs 100 pounds so it wasn’t physically possible My husband has a Five year old convertible Mercedes - he tried to recreate this scenario in his car. The first thing that happens is the emergency brake won’t let him reverse . When he released the brake with the engine off and the radio on it did reverse but the brakes worked normally I have friends with Tesla / BMW / and Range Rover all check their cars and they all have safety features preventing the car to go in reverse or it still has normal brakes My daughter had an accident and luckily nobody was hurt This seems dangerous

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 $5,000 of damage to the car We have $5000 of damage to the house and we will be without a car for 4-8 weeks depending on if parts are here or in Germany

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. The Macan proceeded to roll over two hundred feet from the impact, jumped two curbs, crossed a street with active traffic, and finally stopped when it hit a tree. There was extensive damage to my vehicle but fortunately there were no injuries because the Macan was unmanned at the time of impact. If there were pedestrians and/or other vehicles crossing the path of the Macan they would have been hit. There were no warning signs prior to the failure. This incident has been reported to Porsche Cars North America, Inc. ("PCNA"). I requested an inspection of my vehicle at an authorized Porsche repair dealership but was told: "PCNA has determined that our involvement would not be required in this matter therefore, we are unable to investigate it further". PCNA has disavowed any responsibility for the manufacturer's defect that endangers other drivers, pedestrians and me, given the risk of reoccurrence.
