THE AIR BAG SENSOR IN MY VEHICLE FAILED SHORTLY AFTER ITS 'BUMPER-TO-BUMPER' WARRANTY EXPIRED. ANY PASSENGER IN THE CAR FACES ADDED RISK IF AN ACCIDENT WERE TO OCCUR. IT IS MY UNDERSTANDING THAT THE OWNER'S COST TO FIX THIS ITEM IS PROHIBITIVE ($500 - $1000), AND THAT THE EARLY FAILURE OF THIS PART IS SOMEWHAT COMMON FOR THIS VEHICLE. I BELIEVE THIS SHOULD BE A RECALL, AND THE DEALER SHOULD HAVE TO COVER THE COSTS NOT THE CAR OWNERS. THIS SEEMS SO MUCH LIKE CONSUMER FRAUD TO ME. A THOUSAND DOLLAR PART GOING OUT AT ONLY 35K MILES THAT IS AN INCREDIBLE NUISANCE. *TR
THE AIRBAG LIGHT WILL NOT GO OFF. THIS IS SOMETHING THAT NEEDS A RECALL AS THERE ARE TOO MANY PEOPLE WITH THE SAME PROBLEM AND IT COST $1000 TO REPAIR. THAT IS CRAZY FOR A CAR WITH ONLY 40K MILES ON IT!!!! *TR
Official recalls

Consequence & remedy
Consequence: In the event of a crash, if the front passenger air bag does not deploy as intended, the front passenger has an increased risk of injury.
Remedy: The remedy for this recall is still under development. A permanent remedy is currently under development. The recall began February 26, 2018. Owners may contact Pontiac customer service at 1-800-762-2737 or Saturn customer service at 1-800-553-6000. GM's number for this recall is 17036.
14V171000 · Electrical System:ignition
Apr 10, 2014
General Motors LLC (GM) is recalling certain model year 2005-2010 Chevrolet Cobalt, 2006-2011 Chevrolet HHR, 2007-2010 Pontiac G5, 2006-2010 Pontiac Solstice, 2003-2007 Saturn Ion, and 2007-2010 Saturn Sky vehicles. In the affected vehicles, the key can be removed from the ignition when the ignition is not in the "Off" position.
Consequence & remedy
Consequence: If the key can be removed from the ignition when the ignition is not in the "off" position, the vehicle could roll away: (a) for an automatic transmission, if the transmission is not in the "Park" position; or (b) for a manual transmission, if the parking brake is not engaged and the transmission is not in the "Reverse" position. This potential for rollaway increases the risk for a crash and occupant or pedestrian injuries.
Remedy: General Motors will notify owners, and for vehicles that were built with the defective ignition cylinder and have not previously had the ignition cylinder replaced with the redesigned part, dealers will replace the ignition cylinder and cut and, if necessary, re-learn two ignition/door keys for each vehicle. For vehicles that were built with the redesigned ignition cylinder or had the ignition cylinder replaced with the redesigned part, dealers will cut and, if necessary, re-learn two ignition/door keys for each vehicle. The recall began on April 18, 2014. Chevrolet owners may contact General Motors at 1-800-222-1020, Pontiac owners at 1-800-762-2737, and Saturn owners at 1-800-553-6000. General Motors' number for this recall is 14113 for the ignition lock cylinder and key replacement, and 14133 for only key replacements. Note: Until a vehicle has been remedied, owners and operators are advised that when exiting, to be sure that the vehicle is in "Park," or in the case of a manual transmission, that the vehicle is in the "Reverse" position and the parking brake is engaged.

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

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.
