While driving on a major highway ([XXX]) at over 60 MPH, we had a complete and catastrophic system wide shut down of our vehicle, culminating in our car grinding to a halt. This entire process elapsed over a 15-20 second period.  We barely were able to get our vehicle to the "left" shoulder along the median of the highway where we had to sit for over 75 minutes with oncoming traffic racing past us until 911 arrived to tow us.  It was a life-threatening situation where we were virtual "sitting ducks" without any means to remove ourselves from harms way.  The car was immovable and unresponsive. We tried to restart the car with the assistance of our Porsche Dealer but nothing worked.  We had no choice but to pray for our safety. We have completely documented our experience: photos, videos and phone calls with 911. NOTE: your system is not allowing us to upload any of our photos or videos but we would like to provide these to you directly so please reach out to me to let me know how we can share these with you. When the car malfunctioned, it seemed that every alert in the car's computer system flashed in serial fashion - Engine Control Error, P Button Defective, E Sound Error, Lane Assistance Malfunction, Electrical Parking Brake Error. It should be noted that we have had the car for less than two years and have logged a little over 11,000 miles driven. Ultimately, we were towed by flat bed to the nearest Porsche Dealer in White Plains where the car is parked.  We left a message for the service department at the Dealer telling them who we are, what happened and to call us before they begin an inspection.

Steering Gear. It has been replaced and is not available to inspect. I was unable to turn the steering wheel and had an auto accident as a result. The dealer inspected the vehicle and replaced the steering gear under warranty.  It is probable that the defective gear was sent by the dealer to the manufacturer to inspect. The warning lamps activated after the accident.

PORSCHE MACAN 2024 STEERING

Collion Warning alarm came on with full application of brakes with no vehicles in front or behind. No onward traffic either. Visibility was clear, and driving conditions good. Driving at 35-40 mph. Informed dealer three times (and three different individuals) on December 31 and despite a bevy of promises they have taken no action. Placed warning on Macan.com and several other (purported) owners claimed to have experienced an identical issue. This is self-evidently highly dangerous. Lack of responsivess from Porsche dealer  [XXX] ) has also been derisable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

PORSCHE MACAN 2024 FORWARD COLLISION AVOIDANCE: WARNINGS

I was driving home in my 2024 Porsche Macan 4 EV, at about 65 miles per hour on a divided highway.  I had my climate control set to 75 degrees on both the driver and passenger side of the vehicle.  I believe that the air conditioning was set to off.  I also had the drivers seat heated at the max setting.  I was alone in my vehicle.  It was the first time since I owned my Macan that I had set the heat to that temperature.  Approximately 10 minutes into my drive on the highway, I started smelling an acrid smell.  I assumed that the smell was coming from outside of my vehicle.  I could smell the acrid smell, however, I could not see the source of the smell.  Then, I started seeing a very light gray or white smoke coming out of the defroster vents at the base of the windshield. The amount of smoke wasnât overpowering however, I was concerned if the vehicle was going to catch fire.  I opened the driverâs window in an effort to let the smoke get out of the vehicle.  The smoke and the acrid smell lasted perhaps 20 seconds or so; I canât say for sure.  I drove perhaps another five minutes on the highway to my exit and happened to be near my former Porsche dealer.  I brought the vehicle to a halt in their parking lot away from other vehicles. I opened up the front trunk and looked for any issues and attempted to find any hot areas in that front trunk.  I could not locate anything unusual.  I then drove another 10 minutes to get home and parked the Porsche on my driveway.  I didnât experience any further issues this evening.  While searching online for individuals experiencing a similar issue, it appears that the issue results from a defective passenger compartment electric heater (ZX17), detailed here:   https://static.nhtsa.gov/odi/tsbs/2025/MC-11017831-0001.pdf  I will continue to monitor this in the next few days.

PORSCHE MACAN 2024 VISIBILITY/WIPER

My car has intermittently triggered false collision warningsâapproximately 8 to 10 times over ~8,500 miles. Each time, while driving between 20â40 mph with no visible obstacles, the system issued an orange collision alert, sounded an alarm, and abruptly applied the brakes. This sudden braking poses a serious safety risk, as it could cause a rear-end collision. The vehicle has been at the dealer for 14 days and remains there, as theyâve been unable to replicate the issue or find any stored fault codes.
