2005-2007 Cobalt/Pursuit/G5
Front Airbag Non-Deployment
709,741 Vehicles
Cost Estimate: $14.2M-$37.7M Locations: US, CAN, MEX
ETQ N-130454
Condition:
Front airbag non-deployment has been identified in certain crash events. In those events the
ignition switch was in ACCESSORY or OFF.
Root Cause:
• Field incidents involve vehicles going off the road or hitting smaller objects shortly before
a more significant impact.
• The driver’s knee may be interacting with the keys (ignition cylinder location).
• The mass of the keys may be causing the ignition switch to rotate and the torque to rotate
may be below specifications.
Effects: The airbags will not deploy if the ignition is not in RUN.
Number of Reports:
23 allegations of front airbag nondeployment. 28 VOQs for “Ignition Off” while driving.
Service Bulletin: Bulletin #05-2-35-007 – Inadvertent key turning – issued Oct 2005.
Ignition Switch Change: Increased effort for RUN to ACCESSORY.
Rate & Injury Comparison: GMT800 SDM Switch Contact Bounce.
Potential Field Remedy: Add key “inserts” - $14.2M. Replace ignition switch - $37.7M.
Potential Field Action Category: Safety Recall PPAP
Chronology:
10/29/04 PRTS N182276 issued. For ignition key low effort, may turn while driving.
Closed w/o action (Code 19 – part met requirements).
6/23/05 Investigation opened on 2005 Cobalt stall – Focus on key rotation.
6/28/05 Investigation closed: Plan for Bulletin adding insert and possibly changing key
from slot to hole.
11/28/05 Service Bulletin #05-2-35-007 issued to remedy inadvertent turning of key
cylinder (reduce content on key chain and add insert).
4/26/06 Ignition switch PPAP completed with new plunger and spring (effort increase).
No P/N change, production implementation date unknown.
8/1/09 Ignition key changed from slot to hole.
7/1/11 Service Bulletin #05-2-35-007 updated to add model years.
8/24/11 Investigator assigned for airbag nondeployment.

• Ion switch original for 2003 MY.
• For 2005 MY a capacity tooling increase was needed for Cobalt. The part number is the same, and it is not known which cavities were used for Ion and then for Cobalt/Pursuit.
• HHR added in 2006 MY, G5 in 2007 MY.
A One G5 incident, all others are Cobalt.B Ion uses Class 2 architecture which does not record in ACCESSORY. Cobalt, G5 & HHR use the GM LAN
which records to the SDM even with ignition in ACCESSORY
The Chevrolet Cobalt began production with the Saturn Ion ignition switch.All model years Cobalt, Pursuit, G5, Ion and HHR use same ignition switch part number.

Summary Points
A) Combined reports (FPA, VOQs, Tread) indicate that a distinct change occurred during 2007 MY:
B) The non-deployment incident rate for 2005 MY is over 2 times higher than 2006; approx. 3 times higher than 2007 MY.
2005 2006 2007Incidents 11 7 5IPHTV/Yrs Exposure 0.89 0.39 0.30
(Combined IPTV/Yrs Exposure = 0.47 IPHTV)
C) 2005 MY incident rate is higher than the GMT800 (SDM Contact Bounce) field action which was at 0.77 IPHTV at the time of decision.
D) All Model Years show a decreasing trend. Reported non-deployment incidents within the last 5 years are significantly lower compared to the first 4 years of exposure.
2005 2006 2007
2005-2008 8 4 4IPHTV/Yrs Exposure 1.42 0.58 0.81
2009-2013 3 3 1IPHTV/Yrs Exposure 0.45 0.28 0.09
There have been 2 reports in the past 34 months.
E) The change to the ignition switch that was introduced during the 2007 Model Year (possibly Oct ‘06) is directionally correct. Four incidents have occurred on vehicles built after this date.
F) Changing the key from a slot to a hole is directionally correct.

2005-7 Cobalt, G5, Pursuit, 2003-2007 Ion, 2006-2007 HHRCondition:A review of selected Cobalt & G5 frontal crash events indicates some airbag non deploys have occurred where the ignition switch was in accessory or off. The condition appears to be limited to 2005-07 Cobalt & G5 vehicles. The noted field events involve vehicles going off the road and/or hitting smaller objects shortly before a more significant impact.
Questions:– Why no incidents on Ion or HHR
• Ion is Class 2 architecture vs GM LAN on Cobalt and HHR– Both disable SDM with key off, but Cobalt/HHR will store ignition state & crash record while Ion will not– NISM review indicates 2 potential non-deploys for Ion
• Ion has different column shroud which could affect potential for key interaction• Ion customers may be less likely to have the type of crash needed for the condition• Ion has different SDM and supplier than Cobalt• HHR has more clearance to the driver’s knee
– Why no incidents on 2008-10 Cobalt?• Ignition switch was revised to have longer plunger and spring to increase effort (confirmed
10/29/13)– Part number not changed, so implementation date is unknown (Validation complete 4/26/06). Salvage
yard samples included 2007 vehicles with longer plunger (unknown if any had been replaced in service).
Root Cause:– The hypothesis is that during the off road event the driver’s knee is interacting with
the keys and/or the mass of the keys is causing the ignition to rotate

Switch Background
• Ion switch original for 2003. For 2005 capacity tooling was needed for Cobalt. The part number is the same, so it is not known what cavities were used for Ion and then for Cobalt. HHR added in 2006– A change was initiated in 2006 to implement a new printed circuit
board (12861211 Rev 5) and a new detent plunger (741-79378). The taller plunger and spring with more coils completed validation testing 4/24/06. The switch p/n was not changed, so it is unknown when switches with the new content were put into production or service.*
*The change to the plunger and spring was not confirmed until Delphi provided details with that information on 10/29/13

Assessment SDM Change• Changing the SDM power down behavior is high risk. The power moding, fail
safe operation, and diagnostics portion of the SW would need to be modified. – The start up behavior, i.e. driver seat belt reminder would still need to be compliant –
even though there was no change to the “internal power mode” of the SDM on a quick IGN cycle.
– Diagnostics of the IGN line and AOS module (perhaps other U-Codes) would need to be modified
– Changes to the design of the SDM will need to be done by engineers who were not part of the original design team.
• Note that the AOS module is powered from IGN not battery – so it will power off when the key transitions from run. The FMVSS requirement is that the correct airbag state be displayed within 10 secs – so if the SDM shut off delay lasted longer than 10 seconds or if a transition of airbag state happened with 2-3 seconds of power mode change, there may be a violation of this requirement.

Condition:
Front airbag non-deployment has been identified in certain crash events. In those events the
ignition switch had moved from RUN to ACCESSORY or OFF.
Effects: The airbags will not deploy if the ignition has moved from RUN.
Root Cause: The ignition switch torque performance may be below specifications.
Service Bulletin: Bulletin #05-2-35-007 – Inadvertent key turning – issued Oct 2005.
Number of Reports:
• 23 allegations of front airbag nondeployment.
Field incidents involve vehicles going off the road or hitting smaller objects
shortly before a more significant impact.
• 26 VOQs for “Ignition Off” while driving.
• 355 TREAD reports or application of Service Bulletin.
Ignition Switch Change: Increased effort for RUN to ACCESSORY.
Rate & Injury Comparison: GMT800 SDM Switch Contact Bounce.
Potential Field Remedy: Add key inserts on all, replace ignition switch builds < Nov ‘06.
Potential Field Action Category: Safety Recall

Follow-up from December 17, 2013 FADC Review:
1. Forces required to rotate ignition from RUN to ACCESSORY/OFF
• Mass/number of keys
• Road inputs (rough road data – interior accelerations)
2. Knee Clearance to Key Cylinder
• GM Fleet vs. Cobalt
3. Power Mode Deactivation Delay
• Extend the time the SDM algorithm remains active after the vehicle
exits the RUN power mode.

JDP Comparison
Extend the time the SDM algorithm is active after the vehicle exits the RUN power mode:
SDM: Software for power moding, fail safe operation, and diagnostics would require modification.
– Must address driver seat belt reminder (MVSS) on a quick ignition cycle.
– Requires modification to the diagnostics of the IGN line and AOS module (and other U-Codes).
– Software design changes would be done by Conti engineers who were not part of the original design team (originally Siemens).
– AOS: The occupant sensor module is powered from IGN and will power off when the key transitions from run. MVSS requirements for airbag state display would be violated if a transition of airbag state occurred within 2-3 seconds of power mode change.
– Not designed to be programmable. Approximately 25% would require replacement.
– Replacing with a newer (2011 MY) unit requires replacement of all crash sensors and crash testing to develop calibrations.
– Possible introduction of other issues or non-conformances that would be typically discovered in a full IVER.

Summary Points
1. The rate of reported stall or non-deployment incidents has decreased significantly from ‘05 to ‘06 without any known changes.
2. The rate of reported stall or non-deployment incidents from ‘06 to ‘07 has decreased significantly. 80% of the ‘07 MY reports are after the switch change (believed to have occurred Nov ’06).
3. The 2008 and later models do not have any non-deployment allegations. There are no known differences between ‘07 MY (produced after Nov ’06) and these vehicles.
4. The same switch is used on Ion and HHR which have a total of 2 unconfirmed reports.
5. Two thirds (16) of the non-deployment allegations occurred in the 4 calendar years from 2005-2008. Only one third (7) have occurred in the 5 calendar years from 2009-2013.
6. There have been only two non-deployment events in the last 3 calendar years. Random off road crashes should be continuous, not decreasing (91% of the vehicles are still in use).
7. Of the 12 VOQs for 2005MY, all occurred prior to Dec 2007.
8. The 2006MY VOQs (13) are consistent with the most recent Aug 2013.

• HHR added in 2006 MY, G5 in 2007 MY.
A One G5 incident, all others are Cobalt.B Ion uses Class 2 architecture which does not record in ACCESSORY. Cobalt, G5 & HHR use the GM LAN
which records to the SDM even with ignition in ACCESSORY
The Chevrolet Cobalt began production with the Saturn Ion ignition switch.All model years Cobalt, Pursuit, G5, Ion and HHR have the same mechanical properties for the ignition switch.

2005-7 Cobalt, G5, Pursuit, 2003-2007 Ion, 2006-2007 HHRCondition:A review of selected Cobalt & G5 frontal crash events indicates some airbag non deploys have occurred where the ignition switch was in accessory or off. The condition appears to be limited to 2005-07 Cobalt & G5 vehicles. The noted field events involve vehicles going off the road and/or hitting smaller objects shortly before a more significant impact.
Questions:– Why no incidents on Ion or HHR
• Ion is Class 2 architecture vs GM LAN on Cobalt and HHR– Both disable SDM with key off, but Cobalt/HHR will store ignition state & crash record while Ion will not– NISM review indicates 2 potential non-deploys for Ion
• Ion has different column shroud which could affect potential for key interaction• Ion customers may be less likely to have the type of crash needed for the condition• Ion has different SDM and supplier than Cobalt• HHR has more clearance to the driver’s knee
– Why no incidents on 2008-10 Cobalt?• Ignition switch was revised to have longer plunger and spring to increase effort (confirmed
10/29/13)– Part number not changed, so implementation date is unknown (Validation complete 4/26/06). Salvage
yard samples included 2007 vehicles with longer plunger (unknown if any had been replaced in service).
Root Cause:– The hypothesis is that during the off road event the driver’s knee is interacting with
the keys and/or the mass of the keys is causing the ignition to rotate

Switch Background
• Ion switch original for 2003. For 2005 capacity tooling was needed for Cobalt. The part number is the same, so it is not known what cavities were used for Ion and then for Cobalt. HHR added in 2006– A change was initiated in 2006 to implement a new printed circuit
board (12861211 Rev 5) and a new detent plunger (741-79378). The taller plunger and spring with more coils completed validation testing 4/24/06. The switch p/n was not changed, so it is unknown when switches with the new content were put into production or service.*
*The change to the plunger and spring was not confirmed until Delphi provided details with that information on 10/29/13

Salamis, key rings and GM's ongoing sense of humor
BYLINE: CHRISTOPHER JENSEN, Plain Dealer Auto Editor
SECTION: DRIVING; Pg. F1
LENGTH: 696 words
Just when things look so glum for General Motors, what a relief that somebody at the world's largestautomaker still has a sense of humor.
In this case it comes from a GM news release about the possibility that the engine on its 2005 ChevroletCobalt (built by God-fearing and corn-fed Buckeyes in Lordstown) might inadvertently shut off.
The release was issued in response to a short piece in last Sunday's New York Times that accompanied agenerally favorable review of the Cobalt. In the sidebar story, free-lance writer Jeff Sabatini reported that atest Cobalt driven by his wife stalled, apparently after her knee bumped the steering column.
Intrigued, I asked GM in Detroit if there was an official statement. Sure enough there was and it is, pleaseexcuse me, a knee slapper, suggesting that an engine that can be inadvertently turned off is not a safetyproblem.
"In rare cases when a combination of factors is present, a Chevrolet Cobalt driver can cut power to theengine by inadvertently bumping the ignition key to the accessory or off position while the car is running," itbegins.
"When this happens, the Cobalt is still controllable," the release says. "The engine can be restarted aftershifting to neutral." Incidentally, in a telephone interview a GM spokesman said the steering does not lockwhen the engine stalls.
So, if you're whisking along at 65 mph or trying to pull across an intersection and the engine stops, that'swhat you do. Only a gutless ninny would worry about such a problem. Real men are not afraid of temporaryreductions in forward momentum.
The chuckles are not over yet.
"GM has analyzed this condition and believes it may occur when a driver overloads a key ring, or when thedriver's leg moves amid factors such as steering column position, seat height and placement. Depending onthese factors, a driver can unintentionally turn the vehicle off."
The release goes on to say that service advisers are telling customers they "can virtually eliminate" this kindof unintended deceleration by "removing non-essential materials from their key rings."
So this is not an engineering or manufacturing problem, but a problem with clumsy drivers who can't controltheir knees or with those haunted by stories of the Donner Party who have attached a five-pound salami totheir key chain.
Page 1
Never mind that Sabatini, the troublemaker who started this, said the key chain being used was provided byGM and included such weighty items as a key fob and a tag identifying the vehicle as being part of MotherGM's brood.
The release concludes with an explanation of the complexity of ignition systems, apparently an appeal tothose with an appreciation for an in-depth, technical dive.
"Ignition systems are designed to have 'on' and 'off' positions and practically any vehicle can have power to arunning engine cut off by inadvertently bumping the ignition from the run to 'accessory' or 'off' position," itconcluded.
GM says it has no consumer complaints and, in fairness, I could only find one complaint filed with theNational Highway Traffic Safety Administration that might match the ignition-switch situation; even that wasn'tclear.
But a GM spokesman said two GM employees driving Cobalts have experienced the problem.
There is no evidence it is a widespread problem, but you have to admit it is pretty funny to hear somebodypretend that turning off the engine by mistake isn't a safety issue.
But the record for GM automotive belly laughs belongs to correspondence sent to NHTSA by GM's generalcounsel Thomas Gottschalk in which he argued that windshield wiper failures on some 2002 and 2003midsize sport utilities such as the Chevrolet TrailBlazer weren't a safety problem.
Unfortunately, NHTSA apparently does not have a sense of humor: Almost 600,000 vehicles were recalledand the agency scolded GM, accusing it of attempting to conceal a safety defect and suggesting this was notthe first time the automaker could have been more forthcoming. Then it fined the world's largest automaker arecord $1 million.
GM said the automaker chose to simply pay the fine to avoid the expense and hassle of a long court case.

3/31/2014 Making a Case for Ignitions That Don't Need Keys - New York Times

Making a Case for Ignitions That Don't Need KeysBy JEFF SABATINI
CHEVROLET dealers are telling Cobalt owners to lighten their key rings to prevent intermittent stalling and the loss of electrical power in their cars. GeneralMotors issued a service bulletin to dealers suggesting this fix.
"In rare cases when a combination of factors is present, a Chevrolet Cobalt driver can cut power to the engine by inadvertently bumping the ignition key to
the accessory or off position while the car is running," Alan Adler, a manager for safety communications, said. "Service advisers are telling customers they
can virtually eliminate this possibility by taking several steps, including removing nonessential material from their key rings."
During my time with the Cobalt, I encountered the problem once, or rather, my wife did. She was driving on a freeway when the car "just went dead," in herwords. She recalled bumping her knee against the steering column just before the car shut off. She was able to coast to the shoulder of the road, where,
once parked, the car started and behaved normally.
The only things on the ring, other than the key, were the fob for the remote locking system and a tag identifying the car as G.M.'s - just as the key ring was
given to me.
Though my wife was able to continue to her destination, I wanted a dealer service department to look at the car. Young Chevrolet Oldsmobile Cadillac, in
Owosso, Mich., found nothing wrong, but did share the service bulletin.
Curious whether this experience was indeed rare, I searched the Internet for others who had encountered the same problem. I found a newspaper review
describing the writer's experience with a Cobalt that unintentionally shut off.
"Unplanned engine shutdowns happened four times during a hard-driving test week," Gary Heller wrote in The Daily Item of Sunbury, Pa., on May 26. "I
never encountered anything like this in 37 years of driving. I hope I never do again."
Mr. Adler said that G.M. did not currently consider this situation a safety issue. "When this happens, the Cobalt is still controllable," he said. "The engine can
be restarted after shifting to neutral. Ignition systems are designed to have on and off positions, and practically any vehicle can have power to a running
engine cut off by inadvertently bumping the ignition from the run to accessory or off position."

Subject: Ignition Switch may Turn Off
Dear Ms. Benavides:
This letter serves to acknowledge General Motors LLC's notification to the National Highway Traffic Safety Administration (NHTSA) of a safety recall which will be conducted pursuant to Federal law for the product(s) listed below. Please review the following information to ensure that it conforms to your records as this information is being made available to the public. If the information does not agree with your records, please contact us immediately to discuss your concerns.
Makes/Models/Model Years: CHEVROLET/COBALT/2005-2007 PONTIAC/G5/2007
Mfr's Report Date: February 7, 2014
NHTSA Campaign Number: 14V-047
Components: ELECTRICAL SYSTEM:IGNITION:SWITCH
Potential Number of Units Affected: 619,122
Problem Description:General Motors LLC (GM) is recalling certain model year 2005-2007 Chevrolet Cobalt, and 2007 Pontiac G5 vehicles. In the affected vehicles, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence:If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Remedy:GM will notify owners, and dealers will replace the ignition switch, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet at 1-800-222-1020 or Pontiac at 1-800-762-2737. GM's number for this recall is 13454.
Notes:Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
As required in Part 573.6(c)(6), in the case of a defect, please provide a chronology of all principal events that were the basis for the determination that the defect related to motor vehicle safety, including a summary of all warranty claims, field or service reports, and other information, with their dates of receipt. Please provide this information as soon as possible. Please be reminded of the following requirements: You are required to submit a draft owner notification letter to this office no less than five days prior to mailing it to the customers. Also, copies of all notices, bulletins, dealer notifications, and other communications that relate to this recall, including a copy of the final owner notification letter and any subsequent owner follow-up notification letter(s), are required to be submitted to this office no later than 5 days after they are originally sent (if they are sent to more than one manufacturer, distributor, dealer, or purchaser/owner). You are required to provide an estimated date including month, day, and year, when you will send notifications to owners, dealers, and distributors as soon as it becomes available. Please be reminded that it is expected owners will be notified of a safety defect in their vehicles within 60 days of a manufacturer's notification to NHTSA of a safety defect in those vehicles. As stated in Part 573.7, submission of the first of six consecutive quarterly status reports is required within one month after the close of the calendar quarter in which notification to purchasers occurs. Therefore, the first quarterly report will be due on, or before, 30 days after the close of the calendar quarter. On August 20, 2013, NHTSA announced new changes to the requirements governing safety recalls. Some of these requirements are already in effect. Please ensure your company will be in compliance with each requirement on, or before, its respective effective date.

Your contact for this recall will be Kelly Schuler who may be reached by phone at (202) 366-5227, or by email at [email protected] or through the office email at [email protected]. We look forward to working with you. Sincerely,
Jennifer Timian Chief, Recall Management Division Office of Defects Investigations Enforcement
