On the 2010-2025 Porsche Panamera, the Panamera PASM air suspension shares components with the Cayenne and suffers similar failures. Air strut bladders crack and leak, overworking the compressor until it burns out. The Panamera's lower ride height compared to the Cayenne makes air spring damage from road debris more common.

Common Symptoms

Vehicle sagging on one corner overnight
Suspension fault warning
Compressor running continuously
Harsh ride quality
Audible air leaks

How to Fix

Replace failed air struts and compressor. Inspect all four struts when replacing one — they typically age at similar rates. Arnott and Bilstein offer quality aftermarket options.

TipWhen replacing air struts on a Panamera, always replace the compressor relay as well — a worn relay causes the compressor to run beyond its duty cycle and overheat.

Typical repair cost:$1,500 - $4,500

On the 2010-2025 Porsche Panamera, the Panamera is prone to excessive parasitic battery drain when parked, often caused by modules failing to enter sleep mode. The numerous electronic systems (air suspension, PDCC, keyless entry, PCM) can draw excessive current when the car is off. The battery can drain to the point of no-start within 1-2 weeks of non-use.

Common Symptoms

Dead battery after 1-2 weeks of non-use
Slow cranking after sitting
Dashboard warning lights after jump start
Battery replacement needed every 2-3 years
Keyless entry intermittently not working

How to Fix

Perform a parasitic draw test to identify the offending module. Common culprits include the PCM head unit, telephone module, and comfort access system. Install a battery maintainer for vehicles that sit for extended periods. Replace the battery if it has been deeply discharged multiple times.
