Is the Porsche Panamera reliable?
Overall, the second-generation Panamera is a reliable, well-built luxury GT, hence reliability shouldn't be a cause for concern. Being a Porsche, running costs are high, especially if you get your car serviced or repired at a main dealer.
That said, there are plenty if reputable independent specialist which can carry out high standard repairs for a more reasonable fee.
Gearbox: Take a long test drive to run the car up through the gears. Rough shifting, jerkiness or a delay in the engagement of a gear could spell issues with the PDK automatic ‘box. The cause can vary (internal sensor, control module, clutch).
Suspension: Be wary of any car fitted with air suspension. Any leaks can cause it to sag or sit lower than normal. Faulty air compressors can also cause the suspension to inflate or deflate infrequently.
Other things to watch out for are a broken height sensor, blocked valves or a busted control module. Just one new air strut can exceed £1000.
Engine: A drop in coolant level or engine overheating could mean that the coolant expansion tank or water pump has failed. A new water pump can cost between £200 and £350.
Overheating at idle is typically caused by a broken auxiliary coolant pump. A new one costs between £70 and £200.
Electrics: A frozen infotainment system, screen or audio malfunction are all common examples of electrical and software gremlins. Updating the car’s software regularly can prevent this.
