Equipment

2018-04-26 · campaign 18V267000 · 6,154 vehicles

These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk and remedy

Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

Remedy: GM will notify owners, instructing them to contact Kidde to get a replacement fire extinguisher, free of charge. The recall began June 11, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020, GMC customer service at 1-800-462-8782, and Isuzu customer service at 1-866-441-9638. GM's number for this recall is 18146.

Fuel system, gasoline: storage, auxillary tank

2017-10-19 · campaign 17V664000 · 35,292 vehicles

General Motors LLC (GM) is recalling certain 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.

Risk and remedy

Risk: If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.

Remedy: GM has notified owners, and dealers will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary, free of charge. The recall began December 11, 2017. Owners may contact GM customer service for Chevrolet 1-800-222-1020 or for GMC customer service at 1-800-462-8782. GM's number for this recall is 17399.

General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.

Risk and remedy

Risk: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.

Remedy: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC).

In the affected vehicles, the transfer pump which moves fuel from the rear tank to the front tank could malfunction and cause the fuel gauge to indicate an inaccurate reading.

Risk and remedy

Airbag

2021-02-05 · campaign 2021-025 · 614 vehicles

Issue: Long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, may eventually degrade the propellant contained in the passenger-front airbag. This could cause the airbag to deploy with more force than normal. If the airbag inflator ruptures, fragments could be propelled toward vehicle occupants or cause damage to the airbag assembly, preventing its proper function. Note: This recall is for vehicles that were originally sold or ever registered in certain areas of the United States that experience high or moderate levels of heat and humidity, and that were subsequently imported into Canada. Affected states: American Samoa and the U.S. Virgin Islands, Alabama, Arizona, Arkansas, California, Delaware, District of Columbia, Florida, Georgia, Guam, Hawaii, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Puerto Rico, South Carolina, Tennessee, Texas, the Northern Mariana Islands (Saipan), Virginia and West Virginia. Safety Risk: If the vehicle is involved in a crash requiring an airbag deployment, the airbag inflator could rupture and create a risk of injury. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the passenger-front airbag inflator. Note: This recall is being conducted as a precaution to address future risk. It is expected that all airbag inflators will be replaced before their function would be affected.

Issue: On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, may eventually degrade the propellant contained in the passenger-front airbag. This could cause the airbag to deploy with more force than normal. If the airbag inflator ruptures, fragments could be propelled toward vehicle occupants or cause damage to the airbag assembly, preventing its proper function. Safety Risk: If the vehicle is involved in a crash requiring an airbag deployment, the airbag inflator could rupture and create a risk of injury. Corrective Action: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the passenger-front airbag. Note: The Canadian climate results in the propellant degrading slowly. This recall is being conducted as a precaution to address future risk. It is expected that all airbag inflators will be replaced before their function would be affected.

Fuel system

2017-10-20 · campaign 2017-511

On certain vehicles equipped with gasoline engines and dual fuel tanks, the fuel level sensor in the front tank could become stuck in the low level position, causing the rear tank to overfill the front tank. If this occurs, the front tank could expand and come in contact with the moving drive shaft which, over time, could create a hole in the front tank and cause a fuel leak. A fuel leak in the presence of an ignition source could result in a fire causing injury and/or damage to property. Correction: Dealers will replace the rear tank fuel pump module or flash the vehicle software. Dealers will also inspect the front tank for damage and replace it as necessary.

Electrical

2014-12-30 · campaign 2015-002

On certain vehicles, a defect in the ignition lock cylinder could cause the key to stick in the "start" position if the vehicle interior temperature is sufficiently high. If the vehicle is operated in this condition and the interior temperature cools or the vehicle goes off-road or is subjected to some other jarring event, the key could move out of the "start" position, rotate past the "run" position and into the "accessory" position. If this were to occur, engine power, power steering and power braking would be affected, increasing the risk of a crash causing injury and/or damage to property. The timing of the key movement out of the “run” position, relative to the activation of the sensing algorithm of the crash event, may also result in the airbags not deploying in a subsequent collision, increasing the risk of injury. Correction: Dealers will inspect the steering column for identifying information and replace if necessary.

Fuel system

2013-12-13 · campaign 2013-438 · 342 vehicles

On certain pickup trucks equipped with a 6.6L diesel engine and dual fuel tanks, the fuel tank transfer pump may malfunction, stopping the transfer of fuel from the rear tank to the front tank. This could cause the fuel gauge to display an inaccurate reading, and cause the front tank to become empty while fuel remains in the rear tank. This could result in engine stalling which, in conjunction with traffic, road conditions, and driver's reactions, could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will replace the fuel transfer pump.
