Pontiac G6 GTP / GXP

2005–2010 · Epsilon · sedan

G6 was Pontiac's Epsilon-platform mid-size (sedan, coupe, retractable-hardtop convertible). GTP (2006-2007) ran the 3.9L LZ9 pushrod V6 (240-227 hp). For 2008 Pontiac renamed it GXP and switched to the 3.6L LY7 DOHC V6 (252 hp). FWD only. 4-speed automatic on GTP; 6-speed 6T70 from GXP onward.

Watch out: Power-steering motor failures are the killer (electric assist on FWD GM-Epsilon cars is widely known to fail) — a multi-thousand-dollar fix on a now-cheap car. 3.6L LY7 timing-chain stretch is the secondary issue. Retractable-hardtop hydraulics on the convertible leak with age.
