SUPPLEMENTARY INFORMATION:
Introduction
Interested persons may petition NHTSA requesting that the Agency
initiate an investigation to determine whether a motor vehicle or an
item of replacement equipment does not comply with an applicable motor
vehicle safety standard or contains a defect that relates to motor
vehicle safety. 49 U.S.C. 30162(a)(2); 49 CFR 552.1. Upon receipt of a
properly filed petition, the Agency conducts a technical review of the
petition, material submitted with the petition and any additional
information. 49 U.S.C. 30162(a)(2); 49 CFR 552.6. The technical review
may consist solely of a review of information already in the possession
of the Agency or it may include the collection of information from the
motor vehicle manufacturer and/or other sources. After conducting the
technical review and considering appropriate factors, which may
include, but are not limited to, the nature of the complaint,
allocation of Agency resources, Agency priorities, the likelihood of
uncovering sufficient evidence to establish the existence of a defect
and the likelihood of success in any necessary enforcement litigation,
the Agency will grant or deny the petition. See 49 U.S.C. 30162(a)(2);
49 CFR 552.8.
Background Information
In a letter dated December 12, 2019, the petitioner, Mr. V.T.
Wakefield, requested that NHTSA initiate an investigation into
passenger compartment fires in Model Years (MY) 2006-2010 Saturn Sky
and Pontiac Solstice vehicles. The petitioner alleged the fires were
caused by the overheating of the HVAC blower motor connector. The
petitioner further alleged that Saturn Sky and Pontiac Solstice
vehicles experience the same electrical problem (overheating HVAC
blower resistor) addressed by NHTSA Safety Recall 15V-421, which
involved MY2006-2010 Hummer H3 and 2009-2010 Hummer H3T vehicles. The
petitioner's complaint reported that the affected parts in the Sky and
Solstice vehicles are identical to those covered by Recall 15V-421.
NHTSA has based its decision on a review of the material cited by
the petitioner in his complaint and petition, information submitted by
GM in response to the Agency's information request letter, and other
pertinent information in NHTSA's databases.
Summary of the Petition
The petitioner alleges that MY2006-2010 Saturn Sky and Pontiac
Solstice vehicles can pose a fire risk due to the overheating of the
HVAC blower motor connectors. The petitioner cites the fact the Sky and
Solstice vehicles use the same blower motor parts as the Hummer H3 and
H3T vehicles that were recalled under Safety Recall 15V-421 for a
potential fire risk.
GM filed Safety Recall 15V-421 on June 15, 2015 to remedy the
connector module that controls the blower motor speed in the HVAC
system of MY2006-2010 Hummer H3 and 2009-2010 Hummer H3T vehicles. The
module may overheat under extended operational periods at high and
medium-high blower speeds in those vehicles. The recall followed eleven
(11) related fires affecting a fleet of 165,000 vehicles with five to
ten years of time in service.
Office of Defects Investigation Analysis
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 was with a MY2008 Saturn Sky that had
substantial field exposure including a frontal crash that occurred one
month prior to the August 2017 thermal incident. The Saturn Sky thermal
incident was reported as plastic dripping from the dash and a fire in
the carpet. A root cause could not be identified for this thermal
event.
The other incident was with a MY2007 Pontiac Solstice. The owner
did not inform the manufacturer nor take their vehicle to a dealer for
evaluation after reporting an electrical smell and observing smoke in
the glove box in December 2016. No inspection of the vehicle was
conducted.
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 the 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
Agency'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 Agency. 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. The HVAC blower motor was not confirmed
[[Page 62496]]
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. As
with all potential motor vehicle safety risks, NHTSA will continue to
review any new information or incidents as they are submitted to the
Agency. The denial of this petition does not foreclose the Agency from
taking further action if warranted or making a future finding that a
safety-related defect exists based on additional information the Agency
may receive.
