Example complaints

Engine: “I was driving on interstate 15 northbound when I felt the rear end of my car slip. I was traveling at approximately 70 mpg in 5th gear on a 68 degree evening. I looked in my rear view mirror and saw smoke / steam coming out of the engine compartment. I pulled over as soon as I could, which was approximately 1 minute later. This is exactly what happened in NHTSA action pe13009.”

NHTSA complaint #10681862, filed 2015-02, 51,285 miles

Engine cooling: “The coolant line connectors that come out of the engine / block are dislodging from the engine blocks and blowing out all of the coolant in a matter of seconds. Porsche used some sort of adhesive to hold the connectors in the block instead of welding them in; as the cars age and go through lots of heat cycles, the adhesive is wearing out and the connectors are blowing out of the engine block causing a massive coolant dump which can be dangerous if traveling at freeway speeds.”

NHTSA complaint #10450233, filed 2012-03, 54,000 miles

Vehicle speed control: “I was driving my vehicle down the highway while accelerating when I felt the car squirm and noticed a large cloud of smoke billowing from the rear of the vehicle. I pulled over and identified the issue as a catastrophic coolant leak from the engine area (rear) of the vehicle. I had the vehicle transported home and then to a repair shop where they identified the problem as a coolant line that became separated from the engine block. …”
