2024 Porsche Macan Problems

I drive a leased 2024 Porsche Macan that has been serviced exclusively by Porsche of [XXX]. In May 2026, I brought the vehicle in because the engine was revving/racing while I was driving locally at slow to normal speeds. I also reported that the vehicle initiated sudden collision-avoidance braking when no vehicles or obstacles were present. I was told no problem could be found or replicated. On the morning of XXX while driving about 25–30 mph, the engine again began revving loudly and continued even while I was stopped at a traffic light. This was the same issue I had reported in May. At the next light, I shifted into Park and then back into Drive; the revving temporarily subsided. I stopped briefly at a drive-through pharmacy and then drove directly home. As I pulled into my driveway with my foot on the brake, the vehicle suddenly accelerated sharply on its own and struck my home, causing significant damage to the house and vehicle. Smoke came from the front of the vehicle. Because I live in an attached home and my neighbors were inside, I attempted to back the vehicle a few feet away. With my foot on the brake, I shifted into Reverse, and the vehicle again accelerated sharply, traveling backward at high speed into the street. I steered away from a parked car and a brick wall, pulled the emergency brake, and shut off the vehicle. I exited and called 911. Police arrived within minutes, photographed the scene, and arranged for the vehicle to be towed because it was blocking the street. This vehicle has had unexplained problems repeatedly, yet I was told they could not be replicated. No one was physically injured, but this incident could easily have killed or seriously injured me, a pedestrian, another driver, or a child. I live next to a park and school. I believe this vehicle presents a serious safety risk and should not be returned to service without a complete investigation.

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.

The car's power brake system stopped working. We did not incur an accident just because we found a side road before the upcoming traffic light; otherwise, it would have been a disaster. This car also had other software issues, but it was not as alarming. We believe driving is unsafe. The manufacturer is offering a payment to get back that car and drive it. Still, unless the competent authorities take responsibility for checking that the Porsche Macan EV is safe to drive, our family will not be Porsche's guinea pig. We did not get into an accident just for pure luck, but what will happen if the issue occurs again? The car is under warranty, but another power brake failure can be fatal. It is not an easy position to be in.

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.

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 wasn’t overpowering however, I was concerned if the vehicle was going to catch fire. I opened the driver‘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 can’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 didn’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.
