Nissan Patrol: Rear Air Suspension Airbag & Compressor Failure

Y62 Patrol Ti and Ti-L variants equipped with electronically controlled air suspension (ECAS) suffer from rear airbag bladder cracking and compressor pump burnout. The rubber air bladders degrade from UV exposure, heat cycling, and off-road flexing, eventually cracking and deflating so the rear of the vehicle sits noticeably low. The onboard compressor then runs continuously to try to restore ride height, overheating its motor windings and burning out its internal seals. Once the compressor seizes, the vehicle loses all electronic ride height adjustment. Full repair often requires both rear airbag replacement and a new or remanufactured compressor.

• Vehicle sitting noticeably lower at the rear than normal, especially after parking overnight
• Air suspension warning light on instrument cluster
• Audible compressor motor running for extended or continuous periods after startup
• Compressor completely silent and failed after prolonged continuous operation burned it out
• Uneven rear ride height from side to side if only one bladder has failed

1. 1

   Check the rear ride height visually before and after starting the engine.

2. 2

   Listen for the air compressor cycling longer than a few seconds on startup or running continuously.

3. 3

   Inspect rear airbag bladders carefully at fold points and upper and lower mount areas for cracking or perishing.

4. 4

   Scan for air suspension fault codes.

5. 5

   Test raise and lower functions through the full ride height range to confirm compressor output and bladder integrity.

Parts involved: Air suspension strut.

$1,500 to $5,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the air suspension ever failed, sagged, or required any repair or replacement parts?”
• “Have the rear airbags been replaced, and if so when and how many kilometres ago?”
• “Has the air suspension compressor been replaced or rebuilt?”
• “Does the vehicle hold its ride height correctly overnight without dropping at the rear?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
