| Tl-the contact owns a 2004 porsche cayenne s. the contact stated that while driving approximately 50 mph, an overheating indicator light began to illuminate on the instrument panel. the vehicle was taken directly to an independent repair shop where engine coolant was added to the vehicle. while adding the coolant, the technicians noticed that the coolant was leaking out through it's plastic tubing. the vehicle was then towed to an authorized dealer where the plastic tubing for the engine coolant was being replaced with aluminum tubing. the manufacturer was made aware of the failure, but offered no assistance. the failure mileage was 54,500. sm. | |||

| **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! *tr | |||

| 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 responsiblity. | |||

| 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. | |||
