The engine of my Porsche Panamera went into a total failure because of faulty design/parts by the manufacturer (I.e. screws broke inside the camshaft/block). After doing research online, this is a very common problem with Porsche Panamera, even the service manager at the dealership (Porsche of orlando) told me this. Due to this issue, the car, while my son was driving, essentially stopped working and quickly decelerated from 70 mph to a complete stop in a matter of seconds. Luckily, the semi that was behind him managed to avoid a collision which, if such a collision were to happen, could have easily killed my son. Porsche acknowledges that this problem exists and a simple internet search will display multiple complaints of identical problems with this vehicle's engine but Porsche is negligent by refusing to issue a recall on the vehicles susceptible to this problem. Not only is this a hazard, Porsche refuses to issue reparations to owners affected by this problem leaving people like me out of warranty and a car as the only solution is a complete engine replacement which cost more than the car is worth. Even in other countries, namely china, recalls have been issued for this very problem, yet here in the U.S., there has been nothing. This seems to be a common issue with this company as VW, the parent company, was recently sued for lying on mechanical statistics (I.e. emission reports). I am hoping that you will assist me in making a compelling case and assure that Porsche answers for their negligence and refusal to help its customers.
