What 10 owners told NHTSA about the 2021 Porsche Macan Gts

Water intrusion into the rear of the vehicle flooded due to a manufacturers defect. this area houses the battery and other electrical wiring. The water created a potential electrocution and short of much of the wiring, but the rust contaminated the air quality in the vehicle. Evidence of this corrosion shows persistence for more than a couple of years and the car was inspected twice by the dealer over this time, the most recent a year ago. Since then, I have been diagnosed with several respiratory ailment s along with a lymphoma diagnosis. the cost of the repairs is $7500 and I appealed to the dealer who is repairing the car, the dealer where I purchased the car and Porsche USA corp. all passed on helping me pay for the repairs. there was a lawsuit settlement in 2025 for this very same issue where they exended the warranties for two more years. However, I never received notice to participate in the law suit.

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
