LATCHES/LOCKS/LINKAGES:HATCHBACK/LIFTGATE:LOCK

i have had problems with 3 of the 4 doors not operating correctly. my right rear door does not open at times from the inside or outside. the vehicle has been to the shop 4 times for repair and porshe has been unable to fix it. on 2 of the other doors, sometimes the outer door handles remain in the open position and do not retract after opening the door, often leading to the door reopening when you go to close it. in addition, sometimes the rear hatch does not unlock at times. i have been made aware by 2 porsche dealerships that they have both had other customers with similar or related conditions. this is very serious and has the potential to lead to a very dangerous situation.*ak

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM, PCM)

dt: the contact owns a 2004 porsche cayenne s. while driving up a hill at slow speeds the vehicle will feel as if the transmission is going in and out of gear. this causes the vehicle to jerk, and makes it difficult to control the vehicle. this happens intermittently whether it is warmer or colder temperatures. the service dealer reprogrammed the electronic control module, , but this did not remedy the problem. the service dealer attempted to repair the problem numerous times. the attempts to repair the problem included, updating and the replacement of the transmission control unit. this still did not remedy the problem. the dealer reported the problem to the manufacturer, and they sent a technician to determine the problem. the technician reproduced the problem, and said that it was a condition of hill holder function which holds the vehicle in place to approximately 800-1100 rpms, at which it will start to engage the transmission. the manufacturer stated that this was a normal operating procedure for this type of vehicle when the vehicle wa scold. the contact requested for the manufacturer to submit the reason why this was normal operating procedures for the vehicle. the remedy from the manufacturer was for the contact to accelerate more when going up a hill. the second explanation the manufacturer offered was that the jerking of the vehicle was caused by outside temperatures. the california new motor vehicle board requested that the second explanation be put into writing, but the manufacturer refused. another safety concern bothering the contact was that while driving and upon acceleration the vehicle will stall. when accelerating nothing will happen, the engine will completely lose power. the service dealer stated this was transmission control., but the repairs did not solve the problem. *ak

ELECTRICAL SYSTEM

the rear brake lights (left, right and high mounted) remain lit at all times, as does the rear right and left fog lights. turning lights on or off has no effect. depressing the brake pedal has no effect. this problem has occurred randomly and inconsistently and when the car has been unoccupied and unattended as well as while driving. while unattended, the lights coming on drains the battery and can strand the driver. if problem occurs and the battery is not drained, the driver may be wholly unaware of the problem and may drive with the brake and rear fog lights lit. this problem also creates a major safety hazard as the brake light remain on at all times. following drivers have no way of knowing that the driver may be braking and could result in a serious and potentially fatal rear end collision. the driver of the cayenne, is not aware of the problem. no warning lights are illuminated to make the driver aware. if problem is noticed, removing the fuses for the fog lights and the brake lights corrects the issue, but must be reinserted, allowing for the problem to reoccur. vehicle build date was 12/03 and outside of the porsche wiring harness recall, but this may be the result of a faulty wiring harness feeding the rear of the vehicle.

ENGINE AND ENGINE COOLING

**uncontrolled acceleration** cayenne s accelerated uncontrollably while driving. while driving at approx 60 mph, i encountered traffic ahead and took my foot off the accelerator, however the car began accelerating. i tried lifting the pedal with my foot, no luck, applied the brakes and the car slowed, however, when i removed my foot from the brake, the cayenne continued to accelerate. the cruise control had not been activated and was off. i kept pressing the gas pedal and releasing it at least a dozen times and finally the cayenne stopped accelerating on its own, only to lose any control to accelerate. i coasted into a parking lot and stopped the car. turned it off and restarted - i was able to drive, however acceleration was very slow and gear indicator on the dash cluster displayed a black 'd' in an orange square. this is a symbol that does not exist in the owners manual. the car shifted through gears normally. the rapid uncontrolled acceleration repeated itself and i was able to pull into another parking lot, slowing and stopping the car thanksto massive 14" front brakes with 6 piston calipers and 13"+ rear brakes with 4 piston calipers. i turned the car off for a few minutes and restarted. gear selection indicator appeared normal and i was able to drive off, however acceleration was still veryslow. drove home with the rapid acceleration repeating itself again and then stopping after a few miles. the only reason this did not cause a crash is the massive braking power of the cayenne and astute driving. i ran diagnostic software when i made it home and there was an "accelerator module" failure reported. the tail lights, alarm, central locking, and the ability to open the tailgate at all have also failed - "rear lighting control module" failure. so while driving, my tail lights failed, car accelerated uncontrollably and failed to accelerate in a safe normal manner. this is a major safety issue and should be promptly addressed!

**uncontrolled acceleration** cayenne s accelerated uncontrollably while driving. while driving at approx 60 mph, i encountered traffic ahead and took my foot off the accelerator, however the car began accelerating. i tried lifting the pedal with my foot, no luck, applied the brakes and the car slowed, however, when i removed my foot from the brake, the cayenne continued to accelerate. the cruise control had not been activated and was off. i kept pressing the gas pedal and releasing it at least a dozen times and finally the cayenne stopped accelerating on its own, only to lose any control to accelerate. i coasted into a parking lot and stopped the car. turned it off and restarted - i was able to drive, however acceleration was very slow and gear indicator on the dash cluster displayed a black 'd' in an orange square. this is a symbol that does not exist in the owners manual. the car shifted through gears normally. the rapid uncontrolled acceleration repeated itself and i was able to pull into another parking lot, slowing and stopping the car thanksto massive 14" front brakes with 6 piston calipers and 13"+ rear brakes with 4 piston calipers. i turned the car off for a few minutes and restarted. gear selection indicator appeared normal and i was able to drive off, however acceleration was still veryslow. drove home with the rapid acceleration repeating itself again and then stopping after a few miles. the only reason this did not cause a crash is the massive braking power of the cayenne and astute driving. i ran diagnostic software when i made it home and there was an "accelerator module" failure reported. the tail lights, alarm, central locking, and the ability to open the tailgate at all have also failed - "rear lighting control module" failure. so while driving, my tail lights failed, car accelerated uncontrollably and failed to accelerate in a safe normal manner. this is a major safety issue and should be promptly addressed!

ENGINE AND ENGINE COOLING:ENGINE

the porsche cayenne (and other porsche models) have a coolant leak problem. my vehicle's "low coolant level" light came on. i checked the coolant level and found it to be severely low. the porsche dealer service (and on-line forums) report that porsche cayenne engines are encountering a coolant leak problem that appears to affect all cayenne s, cayenne turbo and cayenne turbo s engines built from 2003 to 2006 (my vehicle is a 2004 model). the coolant leak problem is located in the plastic coolant pipes located under the intake manifold of the engine. according to the porsche dealer, this is a common problem due to the plastic material used by porsche (which has since been changed to a metal material) and the plastic fittings. the lack of coolant can cause the engine to overheat, or even blow an engine, which can be extremely dangerous if this occurs while driving. in order to correct the problem, porsche service says that the coolant pipes must be replaced, which is a very labor and parts intensive service costing well over $1,000.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

coolant pipe start to fail for the model year 2004-2006. the material for coolant pipe was made of plastic and it resulted in a disintegration of pipe overtime due to temperature changes. porsche technicians identified this issue and porsche engineers also identified this issue. they came up with a replacement part which is made of aluminum to mitigate damages to the engine due to sudden failure of coolant pipe. if the pipe busted, it will cause the vehicle to fail during operation and may result in a hazardous incident causing environmental issue and possibly injury to the driver and its passenger. it is highly recommend that porsche to recall this product and replace it for all defect to prevent further incident. additionally, this is an engineering flaw so the cost to repair, replace or to upgrade cannot be the owner responsibility.

ENGINE AND ENGINE COOLING

porsche knowingly manufactured cayenne model vehicles with plastic coolant tubes that degrade and fracture causing engine coolant to leak into the engine, potentially leading to significant engine damage. porsche has known about this defect and failed to make consumers aware of the potential failure despite the risk to the owners safety and pocketbook. *kb

ENGINE

coolant line/plastic coolant hose failure. i was driving in traffic and my low coolant light appeared. within seconds, the car began smoking and the temp. gage rapidly began to rise. i had to turn the car off immediately in the middle of traffic to avoid possible engine failure. i towed the car to my mechanic and he indicated its a design defect from porsche and the plastic tubes are now replaced by orem aluminum tubes. upon further investigation, i was able to determine that the design flaw by porsche was concealed. the cayenne s is in the shop and i'm hoping that only the hoses need replacement and nothing else was damaged due to this issue. a huge dent in the wallet as this is a costly fix.

the porsche cayenne is notorious for drive / cardan shaft failures. had bad drive shaft noises, and subsequent premature failure, it was a worn center support dampener and a faulty center support bearing. i experienced banging, bumping, grinding noises from my porsche cayenne and was unaware at the time it was the drive shaft. i have outlined the the noises and causes below: - a clanking or clunking noise while accelerating or from deceleration to acceleration around 35to 40mph and while cayenne was shifting from 2nd to 3rd to 4th gear. around 5th and 6th gear going around 50-60 mph it stopped. if i kept the rpm under 200 it seemed to run ok, no issue, but if i pressed the accelerator hard or gunned it, it went haywire. it was the result of a worn and damaged dampener or diaphragm located on the center support bearing. this condition will allow for the drive shaft to travel up and down with variations in drive line torque. this movement will produce a loud clanking or clunking sound and make for a very uncomfortable ride. i later found out that this condition is one of the most common failures on the cayenne drive shaft, all models 2003 to 2006. this should be a recall and free fix by porsche because it has happened to so many of the vehicles and model years stated above! but no, porsche quoted me $2,500 to fix it. not fix the problem area, the hard rubber dampener on the center support shaft of the power train, which by the way is possible. no, porsche would only replace the entire power train for $2,500.
