2007 Pontiac
SOLSTICEProblems & recalls

The Office of Defects Investigation (ODI) has completed its review of a Defect Petition received December 12, 2019 requesting an investigation into the possibility of passenger compartment fires attributed to overheating HVAC blower motor connectors in Model Years (MY) 2006-2010 Pontiac Solstice and Saturn Sky vehicles.An analysis of General Motors (GM) complaint data and information in NHTSA?s databases identified thirteen unique vehicle identification numbers (VINs) with reported incidents that could pertain to blower motor overheating, smoking, or melting in the 90,938 MY2006-2010 Saturn Sky and Pontiac Solstice vehicles produced. Two of the thirteen cited incidents reported smoke and thermal damage that may be attributed to the HVAC blower motor although neither incident was confirmed through vehicle inspection. One incident, a MY2008 Saturn Sky with substantial field exposure from a frontal collision, could not have the root cause identified. The other, a MY2007 Pontiac Solstice, did not inform the manufacturer nor take the vehicle to a dealer for evaluation.Most of the 13 incidents reported an overheated or discolored connector with attendant loss of HVAC blower fan function. GM reported 354 warranty claims with the subject components for the Sky and Solstice, none of which included a report of fire and only one report of smoke. Over a period of ten to fourteen years in service, there are two reports of smoke or thermal damage.While the subject Sky and Solstice vehicles and the recalled Hummer H3 and H3T vehicles do share common components, the Sky and Solstice vehicles have demonstrated very different behavior and their HVAC system has a lower power draw than the recalled Hummer H3 and H3T vehicles. The recalled H3 and H3T vehicles generate over triple the failure rate of the Sky and Solstice vehicles. GM suggested in its response to the ODI?s information request that this difference was due to the larger interior volume of a recalled Hummer vehicle imposing a heavier electrical load and duty cycle on its HVAC blower. The duty cycle is defined as how long it takes for the vehicle to cool down enough before the HVAC blower motor fan speed is lowered or turned off completely.Additionally, due to the size differential between the Sky and Solstice vehicles and the recalled Hummer H3 and H3T vehicles, the parts have a different power draw. The Sky and Solstice vehicles, due to their smaller size, draw less wattage, which reduces the likelihood of a thermal event. This condition in the Sky and Solstice vehicles typically leads to an inoperable HVAC blower motor as opposed to a thermal event.Despite the commonality of parts in the Sky and Solstice vehicles with those that were the basis of a safety recall, the subject vehicles have not demonstrated a safety defect trend that would likely lead to a safety recall or merit further investigation by the ODI. The subject vehicles have a low rate of reported thermal events over the ten to fourteen years they have been in service with the most recent occurring in 2017 with no confirmed fires. The HVAC blower motor was not confirmed to be the root cause for either thermal event cited above.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA?s possession, information submitted by GM in response to an information request, and the potential risks to safety implicated by the petitioner?s allegation, NHTSA does not believe that the petition warrants a formal investigation at this time. Consequently, the petition is denied.The entire petition denial can be viewed in the October 14, 2022 Federal Register under DP20-002.(https://www.f

The Office of Defects Investigation (ODI) received a petition requesting the opening of an investigation into the air bag system on model year 2006-2010 Pontiac Solstice and 2007-2010 Saturn Sky, the subject vehicles.The petitioner raised the issue of failure of the Passenger Sensing System for the front passenger seating position.On January 26, 2017, General Motors filed a defect information report recalling the subject vehicles to address the issue raised by the petition.In view of the recall, ODI considers the petition moot and is closing the action.The closing of the petition does not constitute a finding by NHTSA that a safety-related defect does not exist, and the agency reserves the right to take additional action if warranted by future circumstances.

ODI EVALUATED TWO DIFFERENT ALLEGED DEFECTS INVOLVING REAR DRIVETRAIN COMPONENTS DURING THIS PRELIMINARY EVALUATION.GM IS CONDUCTING A RECALL TO ADDRESS ONE OF THE DEFECT CONDITIONS AND ODI HAS OPENED AN ENGINEERING ANALYSIS TO CONTINUE ITS INVESTIGATION OF THE OTHER ALLEGED DEFECT. ON DECEMBER 19, 2007, GM SUBMITTED A DEFECT INFORMATION REPORT TO NHTSA CONCERNING DEFECTIVE REAR AXLE PINION SEALS IN APPROXIMATELY 275,936 MODEL YEAR (MY) 2005-07 CADILLAC CTS, STS AND SRX VEHICLES AS WELL AS MY 2006-07 PONTIAC SOLSTICE AND MY 2007 SATURN SKY VEHICLES (RECALL 07V-589).ON STS AND SRX VEHICLES WITH ALL WHEEL DRIVE, THE FRONT AXLE PINION SEAL ALSO DOES NOT MEET ALL OF GM'S SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK.GM INDICATED THAT THE SEAL SUPPLIER MADE AN UNAUTHORIZED CHANGE TO THE PINION SEAL MATERIAL.LEAKING PINION SEALS COULD RESULT IN LOSS OF REAR DIFFERENTIAL LUBRICATION WHICH COULD RESULT IN REAR WHEEL LOCK-UP AND LOSS OF VEHICLE CONTROL. ON DECEMBER 7, 2007, ODI OPENED AN ENGINEERING ANALYSIS (EA07-017) TO INVESTIGATE COMPLAINTS OF REAR DRIVETRAIN COMPONENT FAILURE (E.G., FRACTURED REAR DIFFERENTIAL CARRIER HOUSING OR REAR AXLE HALF SHAFTS) WHILE DRIVING IN APPROXIMATELY 7,600 MY 2004 THROUGH 2006 CADILLAC CTS-V VEHICLES.THIS CONDITION MAY RESULT IN A LOSS OF MOTIVE POWER AND VEHICLE DISABLEMENT AND IS NOT ADDRESSED BY RECALL 07V-589.ODI IDENTIFIED 35 COMPLAINTS (16 TO ODI AND 19 TO GM) AND 128 WARRANTY CLAIMS POTENTIALLY RELATED TO THIS CONDITION (SEE EA07-017 OPENING RESUME).THESE COMPLAINTS ARE NOT INCLUDED IN THE FAILURE REPORT SUMMARY OF THIS CLOSING RESUME. THE COMPLAINTS AND WARRANTY FIGURES GIVEN IN THIS RESUME ARE LIMITED TO THOSE THAT (A) ARE MOST LIKELY CAUSED BY A LEAKING REAR PINION SEAL; AND (B) RESULTED IN AN ALLEGATION OF A REAR DIFFERENTIAL FAILURE WHILE DRIVING.THE DATA DO NOT INCLUDE ALL REPORTS OF SEAL LEAKAGE.
