Engine And Engine Cooling Problems of Porsche Cayenne - part 1

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.

When car downshifts from 2nd gear to 1st gear, it lunges / jerks forward, even as brakes are applied. Porsche mechanic and Porsche cars north America both indicate nothing is wrong with the transmission. This is a constant issue. Everyday for the last two weeks. Every stop.

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.

The contact owns a 2011 Porsche Cayenne turbo. The contact stated that while starting the vehicle, the vehicle shuddered abnormally. Additionally, while driving, the vehicle experienced a loss of power steering assist, and the brake pedal was firm while depressed. The vehicle failed to come to a complete stop. The traction control, check engine, oil pressure, and several other unknown warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed that the passenger's side camshaft controller and bolts had failed. The dealer determined that both the driver's and passenger's side camshaft controllers and bolts needed to be replaced. The dealer replaced the camshaft adjusters and bolts under NHTSA campaign number: 17v368000 (engine) associated with the VIN; however, the contact was not satisfied with the remedy for the recall. The contact stated that the dealer failed to recover all the failed bolts inside the engine. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 131,046.

My vehicle has camshaft and crankshaft correlation problems due to the well-known problem with its screws and other things. I reported it to Porsche and they told me that it has already been repaired but I don't understand how to fail again and deny help for its repair.

Broken and loosened timing chain cover bolts resulting in leaking oil onto drive components, belts and tires/brakes. This recall was done for the macan and not the Cayenne. Ours was covered under factory extended warranty. That said, this is criminal. Porsche needs to be investigated, they refuse to recall their vehicles and we all know there are some manufaturing issues that are 100% the factory's fault. If the ntsb refuses to hold their feet to the fire this type of engineering will continue.

For the past nine years, my vehicle has recorded multiple safety issues (trunk not closing/breaking, check engine light, catalytic converter misfire, keyless electronic entry issues, glow bulb light, turn signal bulb light, windows not rolling up, leaking fluid on the passenger side, burning smell coming from the vents, electrical issues with the radio, sunroof intermittently not opening/closing and the key not turning the vehicle on. Over the past nine years, I have taken the vehicle to numerous Porsche dealerships per the federal mandate from Porsche USA / Porsche uk. To date, the service manager, chris sansbury and general manager at brian harris Porsche, and Porsche USA, refuse to fix the vehicle. My vehicle is still under factory warranty. I am a person with multiple disabilities. The dealerships (jim ellis Porsche, hennessy Porsche, leith Porsche, brian harris Porsche) have charged me thousands of dollars. I have been extremely sick and desperately need your help. Please help me!.

Problem with the hybrid system and the engine control system. Unit changed automatically and unexpectedly from battery power mode to engine power mode when on battery power mode only. This change is not supposed to happen. This failure happened when starting the unit, put on drive and starting to move forward. This failure caused the unit to charge forward with more power unexpectedly. Causing almost to collide. At the time of the failure “engine control system” warning and “e power not available” warning lid up. The unit has been for service for 10 times with the same warnings powering up. At this time the unit has been on service for almost four month.

I own a 2012 Porsche Cayenne. Transfer case broke at 33,000 miles and was replaced by the dealer, and now it broke again at 55,000 miles. Repair cost is $6,340 plus tax. It broke under the warranty period but Porsche gave me the runaround and told me they wouldn't check it until after some body damage was complete (more details below). Honestly feel like I'm getting gouged with faulty parts. Many other Porsche Cayenne owners seem to be reporting this problem on forums. (e. G. Https://rennlist. Com/forums/cayenne-958-2011-2018/1290994-transfer-case-failure-2. Html) more details - 1. We asked the Porsche dealership to review the car for mechanical issues and repair bumper body damage while the transfer case was under warranty. 2. The Porsche dealer declined to review any mechanical issues until the bumper body damage repair was complete. 3. The Porsche was taken in for service to repair the body work first in late March per Porsche's guidance while the transfer case was still under warranty. 4. The body work was delayed due to Porsche's supply chain issues, and by the time it was complete it was after may 2nd which was when the warranty expired for the transfer case. 5. When the Porsche dealer received the car after may 2nd it identified the transfer case broke. This has been a recurring issue with a car as one transfer case broke at ~33,000 miles and was replaced at a Porsche dealership. Now the second transfer case broke at 55,000 miles (this case only lasted 22,000 miles). 6. Porsche declined to make an exception to the warranty and recommends replacing the transfer case at a price of $6,340 plus tax which will likely last for between 22,000 - 33,000 miles based on prior data points.

While coming to a stop the vehicle lurches around 1200 rpms as the rpms are falling. The vehicle appears to already be in 1st gear when this happens. This can be replicated in all driving modes. Observation: when braking or even when coasting to a stop the vehicle will slow down rapidly, as if the brakes are being tapped hard (the brake pressure is constant and occurs even when not braking) for a brief second and then release causing a lurching motion. This lurching motion is enough to concern while driving as a possible loss of traction. It feels as if the car is engine braking. This issue puts the driver, passengers, and other vehicles at a safety risk. I have had passengers state that it gives them motion sickness. I have reported this to the dealer and they had the car twice. The second time was for a substantial amount of time. The dealer is on record stating that they can recreate it, observe it, but have not been able to fix it. They have reset the software on several systems including the transmission. There are no third party devices on the car, the car is stock, there are no warning lights. This has been the case since day one of having the car (brand new).

After the emissions recall was performed the vehicle has an issue that when turning a corner the engine will not produce any power and will not shift down in order to get the car to accelerate. You get no response from the throttle pedal unless you depress it fully to the floor and then the car will jerk and accelerate uncontrollably. This creates an unsafe condition when trying to pull out into traffic. I have almost been in an accident multiple times because of this with oncoming cars and with cars following me as they are trying to merge also and my vehicle will not accelerate. I have driven a vehicle identical to mine that has not had the emissions recall performed and it does not have this issue.

When slowing almost to a stop, and then need to accelerate, such as slowing for a yield sign, then trying to merge, vehicle is non responsive to throttle input for at least a second, or more. This has put me and others at risk because I assume I'm going to be able to accelerate when pull into traffic and am not able to. The dealer has had the vehicle but was unable to reproduce. It does not always do it, there's some combination of engine, drivetrain or fuel management it's in that does this. I have disabled start/stop mode. There are no system messages or obd errors. The dealer has said that others have experienced this and the manufacturer has told them it's "normal". It's a safety problem and I'm seeking help in getting the manufacturer to fix it. Note, I sent the attached letter to manufacturer and did not receive a reply. I called their customer support line around sept 20th and they did not offer any escalation or other action to address other than writing to their email address. I did this, and received no response.

The day we took our Porsche home, we noticed a lot of heat generation in the car- but we thought it will be fine going further, given the attention to detail of Porsche's automobile engineering. The following days were not any better for my daughter- she missed a major accident because of the unexpected burnt smell and loud warnings of an overheat of the engine by Porsche in the middle of a highway. Due to her excellent driving record for the past 5 years, she was able to manage and stop in the middle of the highway at the curb of the road. She panicked so much so that, she stopped using the Porsche and borrowed our other cars, benz and Lexus. I requested her to give Porsche another chance yesterday night. The same situation repeated again within a span of 10 minutes of her journey in Porsche; she had to stop in the middle of the road again due to engine overheat and burning smell and I went to pick her up as she got really scared. My son immediately informed the hennessey Porsche north atlanta, georgia, the USA about this repeated situation but seems like they do not care at all. I think you must be aware that dealerships play the most crucial role between your loyal customers and Porsche. We have not dared to take the Porsche out again after yesterday. The car smelled so burnt, the whole garage smelled bad and we had to move the car into the open driveway.

Engine oil leak detected in 2021 @33,195 miles caused by broken aluminum bolts in upper part of timing cover.

Parked vehicle and attempted to turn off got a red alert steering faulty,everything locked up including transmission and window switches. . Had to be flat bedded to a Porsche dealership took a week for them to figure out,had to replace steering column. Concern is what would have happened if driving at the time. . Got no answer.

When accelerating the vehicle sputters and catches. This is extremely dangerous if trying to accelerate on a highway or should you need to accelerate to avoid a collision. My vehicle was bought brand new and currently only has 23,600 miles on it. This should not happen to a car with very low mileage. This issue happens while turning, while on the highway, while in reverse, and while on a city street. I took the car to Porsche and they identified that the car needs a new transfer case. This is unacceptable as this is extremely dangerous. This issue seems to have happened on 100s of Porsches.

Intermittent lack of acceleration when taking left turns from a dead stop. Car was a dealer loaner with 9000 miles on speedometer. I purchased the car in August, 2018. Within the first 1000 miles and in less than four weeks I experienced a serious lack of acceleration on two occasions when making a left turn, I reported this to the dealer and was advised that it was probably driver error caused by operating the brake and accelerator using both feet. I do not drive an automatic car using two feet. Also, I was told by the dealer they checked with Porsche and there are records of this type of event. I checked on the internet and there are numerous identical complaints dating back several years. This lack of acceleration has occurred four more times. The dealer has been responsive and kept my vehicle on two occasions to try and duplicate the event to no avail. On one of these occasions the dealer replaced the transfer case but this did not solve the problem. Finally, the dealer called in the Porsche zone manage who I am told was well aware of this condition and referred to it as a safety feature to prevent unintended acceleration. He claimed that this is perfectly normal operation. I call it a safety hazard. In four months I have driven the car 3200 miles. This so-called safety feature has engaged on only six occasions, always on left hand turns from a complete stop. When this happens I never know when the acceleration will cut out or how long I will not be able to accelerate. Up to now, the feature has never engaged in right hand turns, in forward or reverse. I have checked the owners manual carefully and there is no mention of "unintended acceleration" nor is there any mention of a safety feature programmed in the car. I have requested the dealer to by pass or eliminate this feature but thet say Porsche won't allow it.

Porsche cars north America as part of the epa/carb settlement modified the 2015 Cayenne in a manner to comply with the original emissions requirements. The modification has significantly affected performance I such a way that the vehicle is now dangerous in certain situations. When merging onto highways or attempting to overtake there is a significant lack of response to throttle input leading to near misses by other vehicles. This has become more pronounced as the modifications have had time to adapt over time. Porsche has continued to deny an issue and states the vehicle is operating as designed after the modification. This sums up our experience with this vehicle, it is to the point that it is unsafe and dangerous to drive.

Porsche announced their "campaign" (recall) on November 14, 2017. I have called several Porsche dealers since that time, and the parts for this recall are not available. One dealer says it could be "another couple of months" before the part is available. The ah10 campaign says that this situation can cause a fire! is this what Porsche is waiting for? something needs to be done to get them to produce the parts necessary to prevent significant injury or death.
