4 safety recalls, most serious first
1. Equipment
What's wrong, in plain English: A part or accessory supplied with the vehicle. 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/20…
What could happen: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.
The fix: 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…

Component: EQUIPMENT
Summary: General Motors LLC (GM) is recalling certain 2009-2014 Chevrolet Silverado HD and GMC Sierra HD, 2009 GMC Topkick 5000, 6000, 7000 and 8000 Series and Isuzu F Series, and 2009-2018 Chevrolet Express, and GMC Savana vehicles, equipped with certain Plastic-Handle Fire Extinguishers or Push Button 'Pindicator' Fire Extinguishers. 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
Consequence: 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.

2. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.
What could happen: 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.
The fix: 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…

Our Dash board cracked very badly from the top next to the speaker to the passenger side air bag. We purposely use a dash board cover and never place heavy things on it. This is a safety issue as if getting in an accident wouldn’t be bad enough flying shrapnel would be worse. We just had it fixed at a dealership to the tune of $2500. This is not okay as I s…

THE GMC SIERRA 3500HD WHILE IN REGENERATION MODE FUNNELS EXHAUST DIRECTLY INTO THE CAB THROUGH THE VENTS. WHILE GM RECOGNIZED THIS AS A FLAW AND CAME UP WITH A FIX FOR IT, THEY WILL ONLY REPAIR IT IN A 5 YEAR OR 100,000 MILE WINDOW. HOW IS THIS NOT A SAFETY ISSUE WITHOUT AN EXPIRATION?
