“While driving with both of my children in the rain my entire car locked and my windshield wipes stopped my windows wouldn't roll down and my doors locked on and off my alarm system started to go off uncontrollably even while driving Porsche isn't being of any help giving me run arounds also my check engine light came on in the process of the incident”
NHTSA complaint #10852514, filed 2016-03, 152,000 miles“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. …”
NHTSA complaint #10511344, filed 2013-05, 57,000 miles“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.”
NHTSA complaint #11058019, filed 2018-01, 130,000 miles“Car was bought as certified Porsche in mar 2011 with 66k miles; current miles 165k miles; driven approx. For 100k miles in 6 years. Engine clicking noise was getting louder and louder. Told by mechanics that the f cyn. Walls are scored and engine needs to be replace. Checked on-line for this condition with other v-8 Porsche owners to find that it's very common. This seems like a design issue and safety wise ( no power, miss firing and stalling). A $100k new should not have a v-8 engine that has a design defect that is worth less at such low miles.”
NHTSA complaint #10991803, filed 2017-05, 150,000 miles“The contact owns a 2004 Porsche Cayenne S.
