Owners report cascading electrical failures tied to brake system problems: instrument panel warning lights appear (car/lock symbol), gauges jump erratically (speedometer, tachometer, fuel gauge), followed by sudden stalling and brake lockup. One owner experienced multiple brake lockups during highway driving, brakes locking mid-pressure with unresponsive cell phone and OnStar. Despite GM issuing recalls and replacing parts, the issue recurred post-repair, with one owner reporting engine braking by itself after a "fixed" vehicle.
Passenger airbag sensor failures are widespread across 2006-2010 Solstices: the readiness light stays on constantly or doesn't illuminate when the seat is occupied, rendering the airbag inoperative. Diagnostic codes point to a faulty sensor pad design with conductive pathway breakage. Repair costs range $750 to $1,000, yet no recall has been issued despite dozens of reported incidents.
Other electrical failures include key sticking in the ignition, remote entry fobs failing to lock/unlock after storage, and TPMS information disappearing from the dash—with GM acknowledging the firmware fault in a 2008 technical bulletin without informing customers. The A/C blower motor connector harness melts or ignites; the same harness was recalled on Hummer H3 models but not extended to Solstices.
Recall repairs remain incomplete months after notification because parts are unavailable, with dealers and manufacturer unable to provide delivery dates.
Failure modes owners describe
Electrical system malfunction with cascading failures
Instrument panel warning lights (car/lock symbol) appear, followed by gauges jumping erratically (speedometer, tachometer, fuel gauge), fuel warning light, and all system lights flashing on/off. Associated with sudden stalling, unresponsive cell/OnStar, and brake lockup.
When: Reported at 6/14/14 during highway trip; issues persisted even after recall part replacement in Sept 2014 and again 9/22/14
Symptoms owners cite: Car/lock symbol on instrument panel; Speedometer, tachometer, and fuel gauge fluctuating wildly; Fuel warning light and signal; All system lights flashing on/off; Sudden power loss/stalling; Brake lockup during braking; Cell phone and OnStar unresponsive; Engine braking by itself
Repairs/costs cited: GM dealer replaced recalled part mid-June to Sept 12, 2014; issue recurred post-repair
Recalls/TSBs owners mention: Recall NHTSA 14V047000 (Air Bags, Electrical System) and 14V171000 (Electrical System); parts replaced but did not resolve problem
Tire Pressure Monitoring System (TPMS) and remote entry fob failure
After vehicle stored and battery reconnected, remote entry fobs no longer function (doors won't lock/unlock) and TPMS information unavailable on dash. Technician indicated remote entry needed reprogramming. Owner found GM TSB 08-03-16-001B from July 31, 2008, acknowledging bad firmware issue that GM did not disclose to customers.
When: Spring 2017 upon removing from storage; issue discovered 8/10/17
Symptoms owners cite: Remote entry fobs non-functional (won't lock/unlock doors); TPMS information not displaying on dash; Firmware malfunction
Repairs/costs cited: Dealer recommended remote entry reprogramming
Recalls/TSBs owners mention: GM TSB 08-03-16-001B issued July 31, 2008; owner alleges GM hid this safety system issue from customers
Passenger Presence System (PPS) and passenger airbag sensor failure
Passenger airbag readiness light stays on continuously or does not illuminate when passenger occupies seat, rendering passenger airbag inoperative. Service airbag message appears on dash. Fault codes indicate passenger seat sensor pad conductive pathways suffer breakage due to faulty sensor design. Multiple owners report same issue across 2006-2010 Solstices.
When: Reported at various intervals; one case at 60,500 miles (1/25/2013)
Symptoms owners cite: Service airbag message on dash; Passenger airbag light off even when occupied; Passenger airbag readiness light on continuously; Sensor pad conductive pathway breakage
Codes mentioned: B0081-71, 1063 (PP Module)
Repairs/costs cited: Passenger present module replacement (Part # 19124219, Module KI 11.419) cost $607.73 + $138.28 labor; other dealers quote $800-$1,000 for seat component replacement
Recalls/TSBs owners mention: No recall issued despite dozens of reported occurrences; repair costs borne by owners
Ignition switch failure and key sticking
Key becomes difficult or impossible to turn in ignition, or key becomes stuck in on position and cannot be removed. Owner mentioned hard key turning after recall repair.
When: One case reported post-repair in Sept 2014; another case with key stuck
Symptoms owners cite: Key very hard to turn in ignition; Key stuck in on position; Unable to remove key
Repairs/costs cited: One owner requested reimbursement for ignition switch repairs
Recalls/TSBs owners mention: Recall NHTSA 14E021000 (Aftermarket Replacement Ignition Switches) issued; parts unavailable for extended periods
Check engine light and engine control system malfunction
Check engine light illuminates and remains on after dealer clears computer. Light reappears within 10 miles of driving, indicating underlying fault not resolved.
When: Reported after owner had ignition switch replaced
Symptoms owners cite: Check engine light illuminates; Check engine light reappears quickly after clearing
Repairs/costs cited: Dealer cleared computer; no underlying issue found but light returned
A/C blower motor connector harness overheating and fire risk
Wiring harness for A/C fan overheats, melts, or ignites. Blower motor connector module overheating increases fire risk. Same harness used on 2006-2010 Hummer H3 vehicles (Feb 5, 2005 to May 24, 2010) and 2009-2010 Hummer H3T (May 21, 2008 to May 24, 2010), which were recalled, but recall not extended to Saturn Sky or Pontiac Solstice.
When: Multiple reports of melted harness; one recently reported fire incident
Symptoms owners cite: A/C fan wiring harness melting; A/C fan wiring harness ignition/fire; Blower motor connector module overheating
Recalls/TSBs owners mention: Recall extended to Hummer H3/H3T but not to Pontiac Solstice or Saturn Sky
Radio intermittent function
Radio comes on and goes off by itself without user control.
When: Reported in context of ignition switch failure
Symptoms owners cite: Radio turns on and off by itself
Recall part availability delays
Multiple owners unable to complete recall repairs due to extended unavailability of parts. Some recalls pending 6+ months without resolution. Manufacturer and dealers cannot provide specific dates for part availability.
When: Recalls issued 2014 (campaigns 14E021000, 14V047000, 14V171000); parts still unavailable months later
Symptoms owners cite: Parts not available for recall repairs; Extended delays (6+ months reported); No estimated delivery date provided
Repairs/costs cited: Multiple owners unable to schedule or complete repairs due to part shortages
Recalls/TSBs owners mention: Recalls NHTSA 14E021000, 14V047000, 14V171000 issued; parts unavailable for extended periods
