2021 Porsche Macan

Vehicle developed a check engine light and camshaft sensor fault at approximately 48,000 miles. Engine began making abnormal ticking noise and later entered reduced power/limp mode condition. Vehicle was initially evaluated by an authorized Porsche dealership, where damage to the camshaft trigger/tone wheel and internal mechanical concerns within the valvetrain were identified through diagnostic evaluation and bore scope inspection. Supporting documentation from the authorized Porsche dealership, including bore scope video and diagnostic findings, has been retained. A Porsche-focused independent repair facility later identified a fractured rocker arm within the valvetrain assembly as the root cause of the failure. The failed rocker arm caused contact damage to the camshaft and related components. Repair facility advised that further movement of the failed component could have resulted in catastrophic engine failure. Failed component has been retained and documented with photographs. Vehicle required major valvetrain and camshaft repair. Concern involves internal engine component failure at relatively low mileage with potential loss of power and severe engine damage.

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.

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
