Code p1023 fuel pump pressure/ quantity too low at start. Rough start when engine is cold, high pressure fuel pump appears to be leaking. Replacement part is out of stock, unavailable. Unsafe to drive, could start a fire.
Fuel tank is rubbing against the body causing visible rub marks on the plastic tank itself. This is caused by foam pads either being misplaced or not installed at all from the factory. Porsche themselves have a TSB on it (sb-1403), but they will not handle the fix outside of warranty. This seems like a major safety issue where a plastic component holding flammable fuel is rubbing against the metal body and causing a potential failure point where fuel can leak onto hot components. Porsche has stated this is not a safety issue, but I cannot see how that is possibly the case. Many others online are facing the same issue and are getting quotes of $2k usd for the fix to be carried out. Please look into this as I do not feel safe driving my car knowing that the fuel tank can rub itself to failure at any point.
