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.

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.

I was driving at a low speed, less than 30 mph, and was approaching a curve in the road. I attempted to slow down by pressing the brake pedal, but the vehicle did not decelerate. Instead, it seemed to accelerate. I panicked and repeatedly pressed the brake pedal several more times, but the vehicle remained out of control. The vehicle left the roadway, went down a steep slope, struck bushes and tree branches, and eventually came to a stop. All four airbags deployed, and I observed smoke that appeared to be associated with the airbag deployment. The front ,side,underside and lower portion of the vehicle sustained impact damage. At no time before the accident did I observe any warning lights or messages indicating a problem with the braking system or any other vehicle system. Based on my experience during the incident, I believe the vehicle experienced a brake malfunction, as the brakes did not respond when I attempted to slow or stop the vehicle.

There was a recall on the passenger sideair bag sensor for previous years but the issue is still occurring in my 2021 Porsche macan turbo. The error code reports a faulty air bag sensor. The recall should be extended to later year models. Thank you

The sunroof exploded outward as I was driving alone on the road. It was a loud bang and sounded like a gun shot. It scared me and I swerved. Luckily, I did not crash, and the sun visor was closed otherwise, the glass would have fell on me and possibly into my face and eyes - very dangerous! The dealer claimed that a rock probably hit it, but there was no rock that hit my sunroof and the glass blew outward - see attached pics. The sunroof was eventually repaired by the Porsche dealer and paid by my insurance with my deductible. No warning at all. It just blew out! Please check if there is a design flaw with the type of glass used which could affect the structural integrity of the glass with temperature changes and pressure created when opening and closing the doors of the vehicle. The Porsche dealer claimed that they were not accountable, yet I did absolutely nothing to cause this to happen. My insurance has gone up and I lost a lot of time dealing with this.
