Car had a skipping feeling when driving especially when turning. Vehicle has only 20,000 miles and transfer box has to be replaced. They charged me 4660. 47 for the replacement claiming the five year warranty expired. The car is always garaged and used during the winter. When I complained to Porsche they sent me a check for $950.

I was driving the truck and all of a sudden I heard a knocking noise that sounded like the bottom of the car was going to fall off. I made it home and called the dealer. I was advised that this was a common problem and that it was the cardon shaft and it was a common problem. The job I was advised was a $2,000 job. I haven't been able to drive the truck. I finally had it repaired for roughly $900. Very unhappy. . .

Porsche Cayenne 2012. Has transmission casing issues and they are not recalling it! had transmission casing replaced with unmodified part and in less that 25k its broken again. Worry about my safety on the road as im traveling with kids and elderly a lot. They covered first emplacement as the vehicle was under warranty, but refuse to cover second replacement labor costs! its unacceptable! Porsche does not honor their quality, when the part was replaced unmodified in 2015, they were fully aware that this would be a problem down the road and sure enough, it is!! $650 dollars in labor must have been covered as was the second replacement part!!.

Camshaft adjuster bolts failed. . . Vehicle lost power while driving, including braking system and power steering. Porsche recalled some 2011s, but no 2012 were recalled for the same problem. I have kept the faulty parts which match part number with known defect. Porsche would not honor goodwill or any discount, even with proof of matching numbers per the manufacturer.

While driving I heard a loud knocking noise and comming from under the center console and my truck started to shake. I came to a complete stop then proceeded on but once the truck got over 20mph the knocking noise started again .

Tl the contact owns a 2004 Porsche Cayenne. The contact stated he parked the vehicle in his drive way without the emergency break engaged and left to enter his residence. The contact stated within 2-3 minutes later, when exiting his residence, the vehicle inadvertently shifted gears to reverse and rolled away from his residence. The contact stated the vehicle hit two trees, a fence, continued to roll away and hit a second fence which detained the vehicle. Air bags did not deploy. The contact state no one was injured. The contact stated he had to break the rear passenger side window to enter and turn off the vehicle. The vehicle was taken to a body shop for body damage repairs. The contact state at that moment he did not contact the dealer to have the vehicle diagnosed. The contact states he received notification of NHTSA campaign number: 19v446000 (power train) in September of 2019. The vehicle was taken Porsche of omaha (6625 l st, omaha, ne 68117) where the recall repairs were serviced. The manufacturer had been informed of failure. The failure mileage was 90,000.

Upon taking the vehicle out of the driveway I started hearing a ticking sound coming from the engine, something like a lifter hitting the block. I pulled back in to my driveway and called a repair shop and scheduled an appointment. When meeting with the technician I was informed that the engine had a scored cylinder and that it is a common issue with the model and year. The only recourse to fix the issue would be to replace the engine. A replacement engine would cost $17 -35,000 - more than the vehicle is worth. If I were to replace it with a used engine, I would be destined for a repeat of the same issue. If this issue is such a common problem why has there not been a recall for these vehicles? I have contacted the manufacturer and was told that I would need to have a authorized service dealership make the diagnosis I have already been told, but there is not a authorized dealership within 500 miles of my location.

Coolant level appears low all the sudden and pipes r leaking.

Sometime in 2011 I noticed the car began to hesitate when shifting gears (automatic). I was on a long drive from florida to my home in maryland when the first incident occurred. I thought it was just a thing until it began to happen routinely at all speeds. I took it to the dealer and they advised that the valve body would need to be replaced at a cost of $4,500. I missed the warranty period by 60 days so I would have to pay the cost. The truck only had 75,000 miles on it as I usually used my other car for my daily commute. I'm letting the vehicle sit until I can afford such a costly repair. I got the vehicle from a dealer in NY with only 3000 miles on it. I'm certain this was a defect that Porsche knew about and they should offer to foot the bill for the repair.

Vehicle fails to accelerate from a stop intermittently. Vehicle hesitates/ bogs down for 5 to 8 seconds before accelerating regardless of the throttle position. This intermittent failure has not been identified or replicated by the dealer nor repaired. It is a critical safety issue since it impairs the drivers ability to enter flowing traffic safely. The fault has occurred 9 times already.

When rolling slowly (<15mph) 1-2 second stall/bog after pressing accelerator before car accelerates, creating a major safety issue esp when merging with traffic, changing lanes, etc. Porsche north America denies this is a problem after inspection and says its "performing to specification". Separately, several Porsche dealers have verbally acknolwedged and/or confirmed this issue and call it a "first year" hybrid model problem.

I own a 2009 Porsche carrera convertible with pdk transmission. In stop and go traffic and car shifts into neutral for a split second or two before engaging into first gear. My car only has 4,300 miles and this problem seems to be getting worse as time goes on. Porsche told me that they are aware of the problem with no solution at this time. This situation is very dangerous when I am waiting in an intersection wanted to make a left turn and then when I finally it is clear to turn the car would shift into neutral for about a second before engaging into first gear.

I purchased my 2008 Porsche Cayenne turbo as a second owner but before the purchase was completed the coolant hose rupture failure occurred. The repair was at a cost well north of $2000 at the motor werks Porsche of barrington. I also have a 2002 Porsche 996 turbo which just recently ruptured the coolant hose. The cost is once again right around two thousand dollars. I'm just fed up that this epoxy failure within the coolant system which has affected so many Porsche owners. I'm very disappointed that this issue is not fixed even in their later models but very happy to find out that maybe something will arise with these complaints.
