Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
Complaints for the 2018 Panamera are spread across a handful of systems, with the powertrain and electrical system drawing the most reports. On the engine side, owners describe premature water pump failure where the internal seal breaks down and allows coolant to migrate into the vacuum system, contaminating solenoids and change-over valves rather than simply leaking externally. A separate engine complaint describes an overheating warning appearing at highway speed accompanied by a burning smell inside the cabin. One isolated report mentions rocker arm concerns, though that represents a single account. The electrical and powertrain complaints include a report of unintended acceleration during a low-speed parking maneuver, and a ride height sensor failure traced to a plastic mounting bracket on the front suspension that caused the air suspension to lose its ability to maintain proper ride height.

By System
The 2018 Porsche Panamera has 6 recalls, the most serious being moisture intrusion into the climate control system's external coolant pump that can cause an electrical short and start a vehicle fire.
Two of the remaining recalls involve braking. On hybrid variants, the front axle brake lines can corrode over time and reduce braking force, raising the risk of a crash. Separate from that, two recalls cover brake pad wear indicators that fail to alert the driver when pads are worn down to the point where the vehicle may not stop as expected. Several brake-related recalls here only affect hybrid models, while others apply more broadly across the Panamera lineup.
On the steering side, the electric power steering assist can drop out intermittently, making the wheel significantly harder to turn and raising crash risk, particularly at lower speeds where the assist does the most work.
There is also an electrical concern affecting driveability across a wide range of Panamera trims: an unspecified electrical fault can impair how the vehicle responds during driving, which can increase the risk of a crash.
