IN 2009, THE PASSENGER SIDE AIRBAG SENSOR BEGAN TO INTERMITTENTLY FAIL TO DETECT THE PRESENCE OF A PASSENGER. THE PASSENGER RESTRAINT LIGHT SOMETIMES REGISTERED "OFF", EVEN WHEN PASSENGER WAS PRESENT. BECAUSE IT WAS INTERMITTENT, THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE. IN 2014, THE FAILURE BECAME EVER-PRESENT, WITH ADDITIONAL WARNING LIGHTS ON THE DASHBOARD, THE DRIVER INFORMATION SYSTEM, AND AN AUDIBLE WARNING CHIME ON IGNITION START. REPEATED CALLS TO GM HAVE HAD NO RESULTS. THE COMPANY LINE IS THAT THE CAR IS OUT OF WARRANTY, AND THE PRODUCT LINE HAS BEEN DISCONTINUED. THE COST OF REPAIR IS SUBSTANTIAL, APPROACHING $1,000, FOR AN AIRBAG SENSOR MODULE LOCATED BENEATH THE PASSENGER SEAT. ALTHOUGH A COMMON PROBLEM FOR THE 2007 SATURN SKY AND PONTIAC SOLSTICE CARS, GM SAYS THAT THIS IS NOT A SAFETY ISSUE DESERVING A RECALL. *TR

5/14/12 46222 MILES VEHICLE INDICATED A "SERVICE AIR BAG" WARNING - TOOK VEHICLE TO COVERT BUICK DEALERSHIP SERVICE FOR DIAGNOSIS. IT WAS DETERMINED THAT THE PASSENGER PRESENT MODULE WAS FAULTY AND IT WAS REPLACED. 2/10/15 84300 MILES VEHICLE IS AGAIN SHOWING "SERVICE AIR BAG" WARNING. AGAIN PROBLEM WITH THE PASSENGER PRESENT MODULE. IT WAS CONVEYED THAT IF THIS MODULE IS NOT IN WORKING ORDER THE PASSENGER AIR BAG MAY NOT DEPLOY IN THE EVENT OF AN ACCIDENT. IT IS OBVIOUS THAT THIS MODULE IS POORLY MADE TO HAVE ANOTHER FAILURE IN LESS THAN 40,000 MILES. THE PASSENGER SEAT ON THIS CAR IS USED VERY INFREQUENTLY, NO SPILLS OF ANY KIND.

DASHBOARD MESSAGE CENTER INDICATING A "SERVICE AIR BAG" MESSAGE WHEN CAR IS STARTED. RECEIVE THE MESSAGE EVERY TIME KEY IS TURNED ON... I UNDERSTAND FROM OTHER OWNERS OF THE SATURN SKY THIS IS A COMMON ISSUE RELATED TO THE PASSENGER SIDE SEAT SENSOR. GM WILL NOT COVER THE COST TO REPLACE THE SENSOR, EVEN THOUGH IT IS A PART OF THE VEHICLE SAFETY SYSTEM. THE FAILURE OF THIS COMPONENT SHOULD NOT BE CONSIDERED A NORMAL "WEAR AND TEAR" COMPONENT AND/OR A PERIODIC MAINTENANCE ISSUE. GM HAS ISSUED RECALLS ON OTHER GM MODELS WITH THE SAME OR SIMILAR ISSUES, SO WHY NOT THE SATURN SKY. IT SEEMS GM NEEDS GOVERNMENT INTERVENTION AND/OR LAWSUITS, BEFORE IT WILL TAKE ACTION. AS A SKY OWNER I SHOULD NOT HAVE TO BE CONCERNED WHETHER OR NOT MY AIR BAG WILL DEPLOY, DUE TO A DEFECT IN A SAFETY SYSTEM. A CAR OWNER'S EXPECTATION IS THE AIR BAG SYSTEM WILL FUNCTION PROPERLY FOR THE LIFE OF THE VEHICLE, JUST LIKE THE EXPECTATION THE SEAT BELT WILL FUNCTION PROPERLY DURING THE LIFE OF THE VEHICLE. *TR

3DP20002 · Hvac Blower Motor Connector
Opened Feb 7, 2020 · Closed Oct 27, 2022
Status: closed (inferred from source dates) · Electrical System:wiring:interior/under Dash
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
