What is the 2007-2009 Pontiac Solstice Timing chain and balance shaft chain stretch on the GXP 2.0T (LNF)?
The turbocharged 2.0L Ecotec LNF (Solstice GXP) is prone to timing chain and balance-shaft chain stretch as the plastic guides and tensioner wear. A worn tensioner produces a cold-start rattle; if the chain skips timing on this interference engine it can bend valves or damage pis… Repairs typically run $800-$1,800. Severity: high.
What is the 2007-2009 Pontiac Solstice High-pressure fuel pump failure on the GXP (direct-injected 2.0T)?
The direct-injected 2.0L LNF in the Solstice GXP uses a camshaft-driven high-pressure fuel pump that can fail, sometimes with little warning. When the pump loses pressure the engine drops into reduced engine power/limp mode, may misfire, run rough, or stall, and is hard to restar… Repairs typically run $600-$1,200. Severity: high.
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.
What is the 2006-2009 Pontiac Solstice Solstice Trunk Leak with Top Down (Kappa Platform)?
2006-2009 Solstice (and Saturn Sky/Opel GT — all Kappa platform) has the trunk lid integrate with the soft top stowage; with the top down, the trunk seal is exposed and frequently leaks in rain. 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.
