What is the 2006-2010 Pontiac Solstice Ignition switch can move out of "run," stalling the engine?
NHTSA campaign 14V047—not 14V355—supports the frozen ignition-switch safety identity. It covers 2006-2007 Solstice vehicles whose switch can move out of run under key-ring weight or jarring and an expansion for certain 2008-2010 Solstice vehicles that may contain defective servic… Severity: high.
What is the 2006-2010 Pontiac Solstice Passenger airbag suppression (PPS) sensor mat fails, disabling passenger airbag?
NHTSA campaign 17V061 and GM recall bulletin 17036 support the frozen 2006-2010 passenger-presence-system identity. Repeated occupant pressure can bend and damage the flexible sensor mat printed conductor, producing an open circuit; with an active PPS fault, the sensing and diagn… 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 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 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 2006-2010 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.
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.
