📖Buick Park Avenue Shanghai: Australian Zeta rear-wheel-drive flagship demanding strict V6 oil servicing

Buick Park Avenue (Shanghai) (2007-2012)

Manufactured by SAIC-GM from 2007 to 2012, the Chinese-market Buick Park Avenue abandoned front-wheel drive for GM's rear-wheel-drive Zeta architecture, based on the long-wheelbase Holden Statesman/Caprice. Designed as a prestigious executive flagship, it boasted magnificent rear legroom, rear entertainment screens and sublime ride composure. Looking after this rear-wheel-drive titan requires regular Buick Park Avenue maintenance, focusing on timing chain health and drivetrain bushings.

Engine options featured the 2.8-litre (LP1) and 3.6-litre (LY7) High Feature V6 (succeeded by the 3.0-litre SIDI LF1), paired with a 5-speed 5L40-E or 6-speed automatic gearbox. The DOHC V6 engines require short oil service intervals to prevent premature timing chain stretch. The long-wheelbase rear-wheel-drive layout also features a multi-piece prop shaft with a rubber centre support bearing.

Reassuring points

Reliability
  • Sophisticated GM Zeta rear-wheel-drive chassis offering balanced handling and majestic ride quality.
  • Vast rear executive cabin with generous legroom, individual climate controls and rear audio consoles.
  • Substantial build quality and comprehensive QuietTuning sound isolation rivaling European flagships.

Chronic weak spots
