GM recalls trucks with faulty EPS software

 

Warren, Mich. – Aug. 15, 2017 – General Motors has recalled nearly 700,000 vehicles suspected of containing faulty electronic power steering software, according to documents filed with the National Highway Transportation Safety Administration. The campaign affects 2014 Chevrolet Silverado LD pickup trucks manufactured between Jan. 30, 2013 and Sept. 4, 2014, as well as 2014 GMC Sierra LD pickups with production dates ranging from Jan. 29, 2013 to Sept. 4, 2014. GM estimates that 2 percent of the vehicles named in the recall contain the defective EPS software.

The Defect

Vehicles referenced in the recall could potentially contain EPS software prone to sudden shutoff during low-voltage maneuvers such as low-speed turns. The software normally fails within a one-second span, when system voltage measurements drop below 8.8 volts. With the EPS disabled, operators have difficulty navigating the vehicle. This poses a serious safety risk to owners, passengers and other drivers. However, GM has yet to receive any field reports connecting the defective software to any accidents or injuries.

Timeline of Events

On Feb. 2, 2017 GM opened an internal investigation into EPS software installed in some vehicles after receiving multiple customer complaints and vehicle owner’s questionnaires mentioning momentary loss of EPS function. Throughout February and April, the automaker reviewed the collected customer complaints, warranty claims and VOQs to determine if the vehicles referenced in these reports shared similar mechanical features. GM did indeed find technical links between the models and launched an extended field investigation to gather more data, eventually discovering that faulty software was the root cause of the EPS failures.

Over the course of April and May, GM engineers conducted internal tests at the company’s testing facility in Milford, Michigan in an effort to recreate the and evaluate the EPS problem. The automaker was able to gain a deeper understanding of the defective software and its impact on driveability. Engineers discovered that the EPS software stalled in particularly low-voltage situations and required at least 9 volts of electricity to maintain proper operations.

In June, the GM Open Investigation Review re-evaluated the original reports collected in February. On June 22, the car company’s Safety Field Action Decision Authority announced that an official safety recall was necessary. GM notified dealers of the campaign Aug. 7, according to internal documentation submitted to the NHTSA.

The Solution

The automaker has ordered dealers to update the EPS software in affected models with a new iteration released May 19. The repairs are to be administered free of charge. GM plans to notify owners via first-class mail beginning Aug. 15. Those in need of more immediate assistance can contact GM customer service at (800) 462-8782 or the NHTSA Vehicle Safety Hotline at (888) 327-4236.

GM Recalls Vehicles with Faulty Seat Belts

Warren, Mich. – July 10, 2017 – General Motors has recalled more than 40,000 vehicles possibly equipped with dysfunctional software, according to documentation filed with the National Highway Transportation Safety Administration.

The campaign affects over one dozen models across multiple brands, including:

  • 2014 – 2017 Buick Encore sport utility vehicles
  • 2014 – 2016 Buck Lacrosse sedans
  • 2015 – 2016 Cadillac Escalade sport utility vehicles
  • 2015 – 2016 Cadillac Escalade ESV sport utility vehicles
  • 2014 – 2016 Chevrolet Caprice Police Pursuit sedans
  • 2014 – 2017 Chevrolet Corvette sports cars
  • 2014 – 2017 Chevrolet Silverado 1500 pickups
  • 2015 – 2016 Chevrolet Silverado 2500 pickups
  • 2015 – 2016 Chevrolet Silverado 3500 pickups
  • 2014 – 2016 Chevrolet Spark compacts
  • 2014 – 2016 Chevrolet SS sports sedans
  • 2015 – 2016 Chevrolet Suburban sport utility vehicle
  • 2015 – 2016 Chevrolet Tahoe sport utility vehicle
  • 2015 – 2016 Chevrolet Trax sport utility vehicle
  • 2014 – 2017 GMC Sierra 1500 pickups
  • 2015 – 2017 GMC Sierra 2500 pickups
  • 2015 – 2017 GMC Sierra 3500 pickups
  • 2015 – 2016 GMC Yukon and Yukon XL sport utility vehicles

GM suspects 75 percent of the vehicles named in the recall contain the outdated software.

The defect

Affected vehicles contain sensing and diagnostic module software that may not properly deploy front air bags and seat belt pre-tensioning features in the event of an accident.

This poses serious safety risks to drivers and passengers, as they may be left unprotected during collisions. However, the car company has not reports connecting the defective software to accidents or injuries as yet.

Timeline of events

In September of last year, GM recalled more than 3 million vehicles believed to contain problematic SDM software, according to the NHTSA. Approximately 100 percent of the cars involved in the campaign contained the defect.

GM ordered dealers to update the software in all recalled vehicles free of charge, a process that began that very month. Roughly 2.9 million were eventually serviced.

In April 2017, GM personnel conducted an internal audit, reviewing recall and repair records for recent campaigns.

Auditors discovered three instances in which dealers had failed to update the SDM software on vehicles involved in the September 2016 yet reported that the repairs had been successfully executed.

These findings prompted the auditors to evaluate additional repair records and OnStar diagnostic data for approximately 30,000 vehicles named in the aforementioned campaign.

This data indicated that many more models connected to the campaign, an estimated 41,000, might have never received the SDM software update. On May 18, the auditors filed an internal report via the GM Speak Up program.

The GM Safety Field Action Decision Authority chose to conduct an official safety recall June 30. Dealers received notification July 10.

The solution

GM has once again ordered dealers to update the SDM software in affected models. The automaker has pledged to reimburse owners for the repair, according to documents submitted to the NHTSA.

However, GM has not publicized an official notification date for owners.

GM recalls Chevrolet SS vehicles

 

Warren, Mich.—June 26, 2017—A new Chevrolet recall pertains to thousands of vehicles with a potential power steering issue. According to an acknowledgment statement filed with the National Highway Traffic Safety Administration, drivers in certain Chevrolet SS models could suddenly lose electric power steering assistance while the vehicle is in motion. The specific models involved cover the years from 2014 to 2016 for the Chevrolet SS, though the recall itself comes from General Motors.

The Defect

The statement said that a power steering connector could suffer conductivity issues through fretting corrosion, possibly cutting off assistance altogether. This could in turn activate a warning light and noise to alert the driver, even though it might still technically be possible to drive the car. Estimates indicate approximately 95 percent of the 6,204 vehicles may have this issue. The affected components themselves are from Mando Corporation.

Timeline of Events

  • May 14, 2013: This was the earliest production date listed in the same NHTSA statement, applying specifically to the 2013 Chevrolet SS vehicles in the recall.
  • April 27, 2016: The production period for the 2016 vehicles involved in this recall ended on this day, making it the last of all of the included vehicles overall. The report did not list how many vehicles of each model year were included.
  • July 26, 2016: The gold-plated terminals, which were listed as part of the solution to the issue, were introduced on this date. However, the manufacturer reportedly didn’t discover this until it had begun its investigation the following year.
  • September 28, 2016: A related chronology document, also filed with the NHTSA, said that this date was when a report on steering warranty data brought the matter to GM’s attention.
  • March 23, 2017: The manufacturer began its official investigation on this day, with the actual recall decision coming on June 9.

The Resolution

The original statement listed the dealer notification date as June 15, with no date listed for owner notification at that time. The replacements will involve the previously introduced gold-plated terminals to fix the assembly, if such a repair is needed.

Headrest Standards Concerns Lead to Chevrolet Recalls

Detroit — Mar. 02, 2017 — Some Chevrolet Cruze vehicles reportedly have issues with the recliners that could leave the vehicle noncompliant with the Federal Motor Vehicle Safety Standards. Because of this, General Motors Co. targeted 17,197 possibly affected vehicles in the U.S. as part of a recently announced recall action.

The Defect

GM Authority recently reported on the decision. According to the source, the recall would center around improperly secured head restraints. Chevrolet Cruze vehicles from either the 2016 or 2017 model years are part of GM’s concerns. {if they’re just part which vehicles are the rest of GM’s concerns?}

During a crash, the headrests could potentially separate. This not only would put the drivers in possible danger, but would also go against FMVSS 202a the standard that deals with head restraints and comes with height and placement demands.

Timeline of Events

  • July 19-20, 2016: According to an official chronology from GM, the company’s suppliers discovered a welding issue with the affected car brackets on the 19th, and then took measures to improve it the following day, though GM did not learn of this until later.
  • Sept. 16-21, 2016: Three warranty claims for vehicles reportedly containing this defect come to GM’s attention.
  • Nov. 2, 2016: The manufacturer discovered and reported the bracket issue affecting the seat backs.
  • Nov. 21, 2016: GM learned about the supplier actions, among other things, after reaching out to them. 
  • Jan. 9, 2017: The company reviewed the case through its Open Investigation Review board.
  • Jan 19, 2017: After examining relevant computer simulations two days earlier, the company’s Safety and Field Action Decision Authority made the noncompliance recall official.

The Resolution

As a repair document released through the National Highway Traffic Safety Administration said, the fix procedure will take two separate operations: an initial inspection and a follow-up installation, if necessary, to replace the seat back frame.

Chevrolet Suburban Recall To Fix Outside Mirror Issues

Recall Masters – February 28, 2017


Chevrolet Suburban Recall To Fix Outside Mirror Issues

Because of problems with exterior mirrors, some Chevrolet Suburban vehicles are going to be part of a non-compliance recall action, according to documents filed with the National Highway Traffic Safety Administration.

A possible safety issue with these mirrors led to concern over noncompliance with the Federal Motor Vehicle Safety Standards, specifically No. 111, which concerns “rear visibility.” This standard calls for outside mirrors to provide a “view of a level road surface” for the driver.

The Defect
The glass in these mirrors was the source of the issue: Instead of the flat mirror needed for these vehicles, the affected units reportedly came with right-side convex mirrors, possibly distorting drivers’ views while in motion. The recall order included 214 Chevrolet Suburban heavy-duty vehicles with the 2016 and 2017 model years fitted with mirrors from the Michigan-based supplier Magna Mirrors of Americaf…

Chevrolet Suburban Recall To Fix Outside Mirror Issues

Warren, Mich. — Feb. 28, 2017 — Because of problems with exterior mirrors, some Chevrolet Suburban vehicles are going to be part of a non-compliance recall action, according to documents filed with the National Highway Traffic Safety Administration.

A possible safety issue with these mirrors led to concern over noncompliance with the Federal Motor Vehicle Safety Standards, specifically No. 111, which concerns “rear visibility.” This standard calls for outside mirrors to provide a “view of a level road surface” for the driver.

The Defect

The glass in these mirrors was the source of the issue: Instead of the flat mirror needed for these vehicles, the affected units reportedly came with right-side convex mirrors, possibly distorting drivers’ views while in motion. The recall order included 214 Chevrolet Suburban heavy-duty vehicles with the 2016 and 2017 model years fitted with mirrors from the Michigan-based supplier Magna Mirrors of America.

Timeline of Events

  • June 15 to Nov. 10, 2016: The affected Suburban vehicles go through the production process.
  • November 2016: After a line operator notices an incorrect mirror label, General Motors Co. issues an order to stop work on the affected models.
  • December  2016: The manufacturer’s Open Investigation Review team considers the matter as investigations reveal the glass issue and possible FMVSS violation.
  • January 2017: GM officially launches the noncompliance recall through its Safety and Field Action Decision Authority. The Manufacturer’s Report Date is listed as Jan. 12.  

The Resolution

The Part 573 Safety Recall Report said that dealers would replace the previous mirrors with compliant ones, based on FMVSS 111. The glass would be both flat and non-magnifying so as to match the weight-based vehicle requirements and provide an accurate view for drivers.

The safety bulletin related to the recall said that the repair would simply involve two units of the same mirror, and that it would come from GM Customer Care and Aftersales for this necessary replacement supply only, not shelf stock.

Additional Chevy Malibus Recalled Over Takata Air Bag Defect

Warren, Mich. – Dec. 29, 2016 – General Motors will recall certain 2017 Chevrolet Malibu vehicles for defects with Takata air bag inflators. These problems were similar to the reasons that led to a recent recall of 2016 Malibu vehicles.

The Defect

General Motors will recall all 2017 Malibu vehicles manufactured on Nov. 10, 2016, according to documents compiled by the National Highway Traffic Safety Administration. The right-hand rear side air bag inflators in these cars appear to lack sufficient welds, which could cause the inflators to separate at random. As a result, these air bags are at risk for spontaneous deployment that can project debris and cause injury or death among vehicle occupants.

Timeline of Events

  • November 13, 2016 – Takata informed General Motors inflators have ruptured during lot tests of modules.
  • November 14, 2016 – General Motors opened an investigation into the issue and attempted to locate all of the other inflators that originated from the same lot as the failed component.
  • November 16, 2016 – Further tests of the failed inflator confirmed the underlying issue was an incorrect seam weld. No other issues could be found in inflators from the same lot.
  • November 18, 2016 – General Motors decided to conduct a recall on the entire lot, affecting every Malibu vehicle made on November 10.

Resolution

General Motors will send notifications to all vehicle owners containing additional information about the recall schedule. As these cars are still under warranty, no reimbursement will be offered, but dealers will replace the side air bag modules free of charge.

Takata Airbags A Problem For Chevrolet

General Motors has announced a recall of Chevrolet Malibu vehicles from the 2016 model year. These cars are suffering a defect in their Takata-manufactured airbags – marking yet another problem for the embattled company.

The Defect

General Motors will recall 2016 Chevrolet Malibu models manufactured between Nov. 18, 2015 and June 7, 2016, according to documents compiled by the National Highway Traffic Safety Association. The cars have defective modules in their seat-mounted side-impact airbags that may cause the fabric of the airbag cushions to tear during deployment. This increases the risk that the airbags will not perform as designed, threatening the safety of the vehicles’ occupants.

Timeline

  • June 13, 2016 – Airbag supplier Takata discovered the fabric tear during a routine Lot Acceptance Test. Takata informed General Motors and then quarantined the entire shipment of supplies to confirm that the module was the cause of the problem. Specifically, the inflator may have been loaded with more propellant than necessary.
  • June 24, 2016 – General Motors opened an investigation into the issue after a report was filed on its Speak Up for Safety System.
  • July 13, 2016 – General Motors assigned a product investigator to look closely into the module issue.
  • Aug. 11, 2016 – General Motors learned that other inflators not included in the original quarantine may have similar problems, requiring further testing. The company’s Open Investigation Review then sought more data regarding the inflators.
  • Aug. 26, 2016 – Takata told General Motors that it found 18 modules with inflators that were heavier than they were supposed to be – meaning they could contain too much propellant.
  • Oct. 19, 2016 – General Motors decided to conduct the safety recall.

Resolution

Chevrolet dealers will inspect side airbags and replace them at no charge if faulty inflators are detected. Buyers are encouraged to contact their dealer as soon as possible.

Isuzu Faces Accelerator Problems

Isuzu Technical Center has recently announced the recall of NPR and NPR HD vehicles, as well as the Chevrolet Low Cab Forward 3500 and 4500, due to faulty throttle pedals. These components have flaws that could prevent vehicles from decelerating as expected.

The Defect

Isuzu will recall vehicles from the 2014-2016 model years. The throttle pedals on these cars may get stuck under steel stopper bolts, causing the pedal to remain in the full-throttle position, according to documents compiled by the National Highway Traffic Safety Administration. This makes it difficult for drivers to safely stop their vehicles and maintain control while on the road.

Timeline

  • July 2016 – Isuzu learned about a driver of a Model Year 2015 N-Series Gas vehicle who struggled to slow down when letting off the gas. The driver had to hit the brake in order to lose speed.
  • August 2016 – Isuzu received a warranty claim for another vehicle of the same model. Further investigation uncovered that some accelerator pedals may be susceptible to additional lateral force. In addition, the company reopened several prior investigations to see if there was a larger trend that had been missed. One pedal assembly was missing a fastener, while another had an excessively deformed bracket.
  • October 2016 – Isuzu issued the recall for all model years where similar issues have been reported.

Resolution

Isuzu will remove stopper bolts and replace them with flanged plates that will be bolted to the floor. This will prevent lateral movement and lessen straining on the components. This will be done free of charge, and any customer who has already paid for a replacement will be reimbursed.
