What is the 2006-2010 Pontiac Solstice Passenger airbag suppression (PPS) sensor mat fails, disabling passenger airbag?
The Solstice passenger seat uses a flexible PPS sensor mat that decides whether to suppress the front passenger airbag (e.g., for a child). Repeated occupant weight in the same spot bends and cracks the printed conductor in the mat, which can create an open circuit. With an open… Severity: high.
What is the 2006-2010 Pontiac Solstice Ignition switch can move out of "run," stalling the engine?
The low-detent-torque ignition switch can be jostled out of the run position by a heavy key ring, knee contact, or a rough road, shutting off the engine while driving. When the switch drops to accessory/off, the car loses power steering and power brake assist and the airbags are… Severity: high.
What is the 2006-2010 Pontiac Solstice No interior trunk release - trunk becomes impossible to open with a dead battery?
The Solstice has no conventional mechanical/interior trunk (rear deck) release; it opens only electrically via the key fob or door-mounted button. If the battery dies, owners commonly find the trunk locked shut with jumper cables or the battery itself trapped inside. The fob butt… Severity: medium.
What is the 2006-2010 Pontiac Solstice "Reduced Engine Power" limp mode from throttle body coking / TAC faults?
As the car ages, carbon "coking" builds up in the electronic throttle body, slowing the throttle plate response. The throttle actuator control (TAC) system detects a correlation fault between pedal and throttle and drops the car into Reduced Engine Power limp mode. A weak battery… Repairs typically run $100-$400. Severity: medium.

Tiny trunk space (only 3.8 cu ft with top stowed) compounds the issue. Water pools at… Repairs typically run $0-$200. Severity: low.
What is the 2006-2008 Pontiac Solstice Rear differential/driveline clunk and gear whine?
Early Solstices are widely reported to develop a driveline clunk on take-up and shifting at low speed, plus a gear whine from the rear differential that changes with throttle. The clunk is partly an inherent design characteristic, but axle clunk/chatter on turns is caused by stic… Repairs typically run $50-$150. Severity: low.
What is the 2006-2010 Pontiac Solstice Convertible top water leaks into trunk and around rear window?
The folding soft top is finicky and a frequent source of leaks. Water enters the trunk through the holes in the rear deck that accept the top's buttress pins (the seals don't fully seal) and through a slit in the trunk-lid hose that hides the top's flip cable. Owners also report… Severity: low.
