Very strange vibration at cca 3.000rpm and owl-like sounds at 1.800+rpm. The mechanics found out, that "some engine bearing" is on the go, but they can't distinguish which one. Statistics say that 8% of Boxsters die on IMS failure. Selling |
| 46500 mi €50 |
Water leaking from under the engine... Some gasket failed. Definitely this is a terrible car !!! Have to sell it immediately. The whole car is one "Unrepaired Problem". Don't ever buy !!! Leaking oil, leaking water, leaking A/C, smells, smokes, makes noises, vibrates... and fails too often !!! |

Fuel pump failed non-catastrophically. Car was slow to start for a week or two. I assumed that it was the battery due to not driving the car enough. I drove it to Modern Aircooled for a thorough general inspection and oil change, and they identified that the fuel pump was failing to produce needed pressure. The fuel pump was replaced. |
| 102000 mi US $500 |
Water pump failed. It was gushing coolant once the system pressurized and caused bad noises. Belt tenioner roller replaced. Bolt was rounded over and required cutting to remove. Cutting the bolt took a very long time due to lack of access. Bolt was replaced with M10x50mm set screw and lock nut due to lack of access. Replacement pulley used was Sebro brand. |
