Example complaints
Engine cooling: “As I was accelerating for a merge, the car bucked and hesitated despite having my foot on the gas. I shifted gears and it was the same problem then there was an odd noise from the engine. I pulled off and the oil pressure warning light came on just as I stopped the engine. I had the car towed to the repair shop.”
NHTSA complaint #10426021, filed 2011-09, 13,250 milesTires: “Tire failed on the freeway going 65 MPH. No damage to the tire other than the side wall failure. Sidewall totally separated at the bead leaving the tire attached only to the outside rim edge. Continental has refused warranty replacement even though the tire is less than one year old and less than 6,000 miles. Auto was a new Porsche Cayman S.”
NHTSA complaint #10216536, filed 2008-01, 5,600 milesEngine: “Traveling in a straight line on a dry road at around 65mph, the vehicle's engine expired in a huge plume of coolant/oil. Flatbedded to a Porsche dealership, a technician using a boroscope found (according to the dealership) scoring to #5 cylinder and evidence that a valve had hit the top of the piston. There was also a huge amount of metal debris in the oil filter. This was a result of something failing in the engine, rather than the cause of the failure. The Porsche dealership did not care to determine the cause of the failure. I suspect intermediate main shaft (ims) failure. …”
