Chevrolet SSR

The retractable-hardtop pickup, and underneath the unusual body it is a TrailBlazer — the GMT360 frame, that vehicle's rear axle and much of its electrical architecture — so TrailBlazer material covers the chassis and driveline, which is worth knowing because very little was written about the SSR itself. The folding hardtop is where its own faults live: a hydraulic and electrical assembly with its own module, position sensors and interlocks, and a roof that stops mid-cycle reports faults rather than needing to be diagnosed by eye. Early cars use the 5.3; the later 6.0 is the LS2 from the Corvette.
