Owner report 11404548 · 2021-03-23 (March 23, 2021)
THE CAR CAME WITH A FACTORY INSTALLED TOW SYSTEM. I RETURNED IT TO THE DEALER THREE TIMES AND IT DOES NOT WORK PROPERLY. I WAS SHOCKED PLUGGING IN A TESTER TO THE 7 WAY CONNECTOR. THE DEALER SERVICE MANAGER ADVISED ME THAT I WAS NOT SHOCKED AND STATES THAT THE LIGHTS STATING THE 7 WAY CONNECTOR IS NORMAL. THIS IS NOT NORMAL. WHEN I CONNECT A DIGITAL BREAK CONTROLLER OR 7 PIN CABLE WITH A TRAILER THE CAR DOESN'T NOT COMMUNICATE WITH THE BREAK CONTROLLER. THE BREAK CONTROLLER EXPERT STATED THAT SINCE NO DIODE WAS SHOWING WHEN I PLUG THE CAR IN…

Owner report 11427025 · 2021-07-29 (July 29, 2021)
The back up cameras and surround view have failed multiple times since August 2020. Back up cameras were made mandatory safety equipment requirements for all new cars manufactured after 2018 due to safety concerns. The federal government mandated the cameras to prevent “back over” accidents of young children who are not otherwise visible to the driver. There have been multiple attempts to repair the cameras on this vehicle, including replacing all cameras, replacing all wiring harnesses/pigtails, replacing the coax cable for the cameras as wel…

Owner report 11448947 · 2022-01-26 (January 26, 2022)
I applied the gas pedal & the pedal seemed to stick . The vehicle kept accelerating after I took my foot off that pedal to apply brake . Car would slow when brake applied but immediately accelerated and kept increasing (speed was well over 90 mph & climbing ) when brake was released . This happened 3 times before the “stuck”pedal released. Another driver (retired mechanic) had driven the car and had similar experience a week prior and mentioned their experience. I didn’t realize how serious the incident could be. I called dealership but first …

Owner report 11414419 · 2021-04-29 (April 29, 2021)
MY PORSCHE 2020 S HAS BREAKING ISSUES WHEN IN SPORT MODE. WHEN THE CAR DOWNSHIFTS FROM 3RD TO 2ND GEAR, AND 2ND TO 1ST GEAR, THIS IS A SUDDEN JOLT FORWARD OR "LURGING" THAT OCCURS EVERY TIME. THIS IS A SAFETY RISK IN BUMPER TO BUMPER TRAFFIC AS THE CAR CAN SUDDENLY JUMP FORWARD A FEW FEET MORE THAN INTENDED BY NORMAL BREAKING. EVEN WHEN DRIVING AND BREAKING EXPLICITLY TO COMPENSATE FOR THIS TRANSMISSION / BREAKING DEFECT, THE LURGING ISSUE CANNOT BE AVOIDED. THE ONLY WAY TO AVOID THIS ISSUE IS TO (A) BREAK HARD FROM 3RD TO 1ST GEAR (SO FROM…

The car is very jerky, I bought in for engine or transmission mount because the idle shakes the whole car. They said its normal. Which I don't think it's normal.

Owner report 11756293 · 2026-08-11 (August 11, 2026)
Nearly 25% of the total time I have owned this Certified Pre-Owned vehicle (146 out of 564 days), it has been non-functional and in the shop , roughly 1 out of every 4 days of ownership. I am a [XXX} with a [XXX] child, and I purchased this vehicle as a Certified Pre-Owned (CPO) Porsche , expecting the manufacturer's rigorous inspection and warranty to ensure reliability and safety. Instead, the first breakdown occurred within just 1 month of purchase, and the vehicle has since failed six separate times over 18 months (Feb 2025–Aug 2026), total…
