Excess glue caused problems in GM trucks

Laguna Hills, CA – Dec. 20, 2019 – General Motors LLC is recalling certain 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. The B+ battery positive cable rings may have an excess of glue, increasing the likelihood of an intermittent electrical connection

The potential number of vehicles affected is estimated at 350,371.

The Defect

While driving the vehicle, the glue may soften so that the nut that attaches the battery cable to the alternator loosens, causing an intermittent electrical connection. A bad connection could cause the vehicle stall and also cause arcing, which could generate enough heat to start a fire. The defect was caused by an excess of glue that should have been removed from around the B+ battery cable rings during the supplier’s assembly process. The excess glue resulted in glue contamination.

Timeline of Events

General Motors’ Canadian Brand Quality Manage found a case where a 2019 GMC Sierra stalled because it was missing the nut that secures the B+ cable to the alternator stud. On August 20, 2019, the Brand Quality Manager submitted a report to General Motors’ Speak Up For Safety (SUFS) program. GM opened an investigation on September 10, 2019. The investigation found warranty reports of related field incidents. Between September and November, GM experts analyzed parts to determine the cause of the defect and conducted a torque-curve study. Field data analysis was completed November 25, 2019, finding one case of a related fire.

On December 5, 2019, General Motors’ Safety and Field Action Decision Authority decided to conduct a safety recall.

The Solution

Owners of affected vehicles will be notified and told to take their vehicles to a certified General Motors dealer for repairs, free of charge. Dealers will use a black light to inspect for glue and other contaminants at the B+ cable attachment alternator. Dealers may clean the connection and then reattach the B+ cable connection. If any damage has occurred to the alternator, cable or nut will replace the damaged parts. Secondary black light inspection has been implemented in production to catch the defect moving forward. Secondary inspections began November 14, 2019 at General Motors’ Fort Wayne plant and November 22, 2019 at their Silao plant.

Dealers will be notified of the recall beginning on December 12, 2019, while owners will be notified on January 27, 2020.

GM Recalls Pickup Trucks Due to Seat Belt Fire Fears

Laguna Hills, CA – Nov. 21, 2019 – Well over a half-million pickup trucks manufactured by General Motors LLC are poised to be pulled from the marketplace over safety concerns related to the front seat belt pretensioners. When passengers strap themselves in, a hot gas may emit from pretensioner bracket opening. This could cause a fire within the interior of the vehicle. The potentially compromised models in question include the Chevrolet Silverado and GMC Sierra.

Although GM has yet to announce when motorists will be officially notified of this safety issue by mail, the automaker intends to send mailers alerting registered owners shortly. Recipients are urged to have their cars examined by an area dealership so this problem can be resolved, if one exists. The repair comes at no charge.

The Defect

According to documents submitted to and distributed by the National Highway Traffic Safety Administration, GM is recalling approximately 556,399 pickup trucks nationwide whose seat belt pretensioners – both on the driver and passenger side of the car – may be compromised. Upon the belt’s deployment from the assembly, a flammable gas may emanate out of the bracket aperture. Such a scenario may lead to a fire. All the suspect vehicles have carpet floor mats, which are not fire retardant. Those with vinyl floor coverings are not in any danger.

The specific automobiles included in the GM seat belt fire recall are the following:

  • 2019-2020 Chevrolet Silverado 1500
  • 2020 Chevrolet Silverado 2500
  • 2020 Chevrolet Silverado 3500
  • 2019-2020 GMC Sierra 1500
  • 2020 GMC Sierra 2500
  • 2020 GMC Sierra 3500

Chevrolet Silverados represent the lion’s share of the GM seat belt fire recall at 355,878, based upon NHTSA records and estimates.

Timeline of Events

This issue first came to GM’s attention July 25, when corporate headquarters was briefed about a fire occurring within the cab of a GM-manufactured pickup truck. Internal fire investigators participated in the inquiry as well and determined approximately five days later that the problem may be linked to a similar event that involved the same make and model.

GM and the internal fire experts referred the case to GM’s technical center for follow-up analysis and a more in-depth breakdown as to the nature and cause of the conflagration and how best to resolve it. This subsequent investigation took place in September.

In mid-October, those leading the inquiry determined the most likely cause was a hot gas that vented from the pretensioner opening, which subsequently ignited carpet fibers found on the floor. These findings were then submitted to GM open investigation review board Nov. 4. Three days later, the automaker decided a safety recall was appropriate. No known crashes, deaths or injuries have been reported as a result of this seat belt glitch.

The Solution

While General Motors dealers have since been notified about this safety alert, motorists soon will be, according to the automaker’s  records. There’s no official date as of yet, but GM expects mailers being distributed sent out in the first or second week of December. Those informed are asked to bring their automobile to a local dealer. If deemed necessary after inspecting the suspect seat belt unit, the pretensioner aperture will be closed off, thus stopping the gas’s outflow.
