beginning in August 2022, I have had repeated problems with the battery in my 2022 Cayenne. if the car is left sitting for approximately 48 hours, the battery dies and must be jumpstarted. we reported this issue to Porsche immediately and my car has been in with the Porsche service technicians at least three times (August 9, Sept 13, Nov 7) this fall with no success at fixing the problem. (we also had a call telling us to take the car outside for a "software update," which did not work.) we are told this is a problem somewhere in the electrical system and it is affecting other 2020 Cayennes and some 911s. But Porsche has not offered a solution, nor is it being at all proactive in offering assistance or support. we have compensated for the last four months by parking the car in a garage and keeping it on a trickle charger if we are not driving it regularly. However, we were out of town for two weeks over Thanksgiving and the car battery died in spite of being connected to the trickle charger. we had to jump start the car and reset all the car settings. in addition we have had sporadic issues with unlocking and locking the car doors via hand touch. Porsche has been treating this issue as an "inconvenience" rather than what it is - a serious life safety issue. One of the service technicians told me "the car was meant to be driven every day"! I hesitate to drive my car at night because I do not have confidence that the car will start for me on a dark street at night. every day when I come down to drive my car I allow extra time as the car may not start. I have more confidence in my 2013 Toyota Tacoma than in this car in terms of reliability. this is a problem where Porsche has not offered remediation or assistance, nor has it offered a any assistance (I.e., loaner car or any alternative) while my car either been in the shop (for a total of at least two weeks) or has been operating with the (acknowledged) defect.

ENGINE

1 complaint

There is a major issue with the coolant pump/water pump on the V8 4.0L engine. Every 30,000ish miles I’ve had to have a water pump replaced in my vehicle, Porsche NA claims they redesigned the pump and it fails in the same amount of time. Rennlist Porsche worldwide forums there are 28 threads of people having water pumps/coolant pumps replaced at the tune of $9,000-$12,000 because 70-80% of the front end of the Cayenne has to be removed to get to the water pump. The pump needs to be made out of more durable materials for durability and longevity. Expecting customers to replace water pumps every 30K miles is ridiculous. My 3rd water pump in 95K miles is being replaced as I type this right now. The dealership Porsche of Wallingford, CT, has 3 other customer Cayennes now that also need water pumps. Porsche USA and AG/Germany need to issue a 15 year/unlimited miles warranty on this water pump, like they’ve had to do with window switches, emissions valves, and other parts they have gotten sued for and now have 15 year warranties.

POWER TRAIN

1 complaint

Everytime when vehicle coming to a stop car lurches forward few feets. It just happens when car downshifts from second to first gear transmission pushes you forward few feets, You just need to be very carefull because it can push you into another vehicle or pedastrian. Porsche is aware of it and have a software update in Europe only but not in USA

POWER TRAIN,UNKNOWN OR OTHER,SERVICE BRAKES

1 complaint

When downshifting and just before Coming to a complete stop and vehicle lurches/surges forward even though my foot is on the brake pedal. This happens in every drive mode with or without Autostart/stop engaged. It is Significantly challenging in stop and go traffic because it’s difficult to gage when the car will come to a complete stop. I have to make accommodation for the car lunging forward which is unpredictable because sometimes it’s a subtle surge forward and other times I have no control or idea how far forward the car is going to move. This makes this is especially dangerous when cars are quickly changing lanes in front of me in stop and go traffic during rush hour. Emergency braking DOES not help this! I have experience this. The collision warning Went off in the car and emergency braking was engaged just at the Knick of time! Adverse weather conditions could have easily made that a very bad accident. I should be able to Do normal every day driving And stopping, for example stopping to a red light, or stop and go traffic without having to activate emergency functions in my car and putting myself at unnecessary risk because of a “glitch” with Porsche. This normal every day driving. I returned my car to the dealership who told me it’s normal performance for this car along with. I along with many other owners have researched this and found out that software upgrades have been done to correct this problem which are not available yet in the United States. This issue needs to be resolved immediately to prevent potential accidents.

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 available service appointment (scheduled) is Feb. 23,2022

BACK OVER PREVENTION

1 complaint

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 well as module/software updates. The vehicle has been at the authorized service center multiple times with it being there 105 out of the past 112 days; the vehicle was "fixed" for 4 days before the back up camera failed again. The manufacture has been unable to repair the vehicle to have reliable working cameras. We have spoken with others about the same failure of the back up camera system.

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 A FAIRLY HIGH SPEED DOWN TO 0, WHICH LENDS ADDITIONAL BREAKING SAFETY RISKS IN NON-IDEAL WEATHER CONDITIONS SUCH AS BREAKING DOWNHILL OR ON WET / ICY ROADS), OR (B) TO NOT DRIVE THE CAR IN ONE OF THE TWO DRIVING MODES OFFERED. THE MANUFACTURER'S SERVICE DEPARTMENT CLAIMS THERE IS NO ISSUE, BUT SOME QUICK GOOGLE SEARCHES SHOW THIS ISSUE IS EXPERIENCED WIDELY AND WELL DOCUMENTED, AND A SOFTWARE FIX HAS BEEN ROLLED OUT OVERSEAS THAT ISN'T AVAILABLE IN NORTH AMERICA

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 THAT THIS INDICATES THE BRAKES ARE NOT WIRED CORRECTLY. THE DEALERSHIP SAYS SINCE ANOTHER CAR WORKS THE SAME AS MINE THEY DON'T THINK IT IS A ISSUE. CORPORATE PORSCHE IS UNABLE TO ADVISE ON TECHNICAL SERVICE BULLETINS OR INFORMATION ON A WIRING HARNESS TO ENABLE A WIRED BREAK CONTROLLER. I TOOK THE CAR OVER TO UHAUL AND DID REMOTE CALLS WITH THE BRAKE CONTROLLER MANUFACTURER. ALL STATE THAT IT IS SOMETHING WITH THE MANNER IT IS WIRED WITH A 'OPEN GROUND'. THIS IS UNSAFE AS I HAVE NO WAY SAFELY BRAKE OR UTILIZE A BRAKE CONTROLLER. SINCE OTHER 2020S BEHAVE THE SAME WAY THIS IS A SYSTEMWIDE ISSUE AND THE MANUFACTURER IS NOT TAKING ACTION SO IT SHOULD BE EVALUATED BY ENGINEERING.
