2019 Chevrolet Silverado 3500 Problems

Very hard downshift of transmission caused rear wheels to break traction on icy road. Vehicle slid sideways across the road nearly going over the edge of a steep downgrade.

There was oil leaking from my rear wheel causing loss of brakes and lots of smoke, almost caught on fire. Dealer stated that there was a defective rear wheel seal. There was loss of braking control on wet pavement from precipitation.

Def pump and heater module had burned terminals. This caused failure to the def pump and heater module. This was the second instance of this happening on this truck in roughly 40,000 miles. Burned terminals can start electrical fires that are a danger to occupants and others in the vicinity. Failure of this system forces a drop in speed after so many miles that make you a danger on the road.

There is a common and very dangerous electrical wire routing problem on my vehicle, along with 3 dozen others and my dads (separate but same truck) i confirmed with (FB group for owners of 17-19 L5P GMC diesel trucks) where the alternator positive wire from the alternator to the battery is run right along and across a rather sharp part of molding from the air intake tube. This routing location and rough intake plastic molding rubs through the alternator wire creating a possible electrical short/ corrosion problems that can lead to battery and electrical system compromise, as well as fire risk! A short-circuit condition can cause damage to engine components and, in rare cases, start a fire in the engine compartment. I have 92,000 miles on this 2019, my father has the problem starting on his at only 40,000 miles and may others have issues as well to very degrees of severity between 25 and 150k miles. I discovered this issue while performing routine air filter maintenance and happened to see the rub damage. no modifications have been done, this is the way the wire is routed from the factory. IMO and estimations This issue far supercedes the danger and severity of the recall that currently exists for the engine block heater cord for these models of trucks. 2 of the photos show the damage and exposed wire as soon as i found it. The last shows the location and the part that caused the rub damage along with a temporary mitigation method: electrical tape with a rubber hose installed as a buffer until a permanent fix can be installed.

The contact owns a 2019 Chevrolet Silverado. The contact stated that on several occasions at various speeds, the contact observed an exhaust odor coming into the cabin of the vehicle from the vents. The vehicle was taken to two dealers where the failure was not able to be replicated. The manufacturer was notified of the failure. The failure mileage was approximately 60,000.

Driving at hiway speed and towing a 40' travel trailer the transmission failed and put my family in grave danger. GM is aware of this issue as they have issued a service bulletin due to an engineering flaw.... ( transfer case input and out put shaft failure) This needs to be a recall before someone is killed or injured ( wheels locking up at hiway speeds)

1st incident: When driving the vehicle dashboard shut off, no indicators working such as speedometer, gauges etc and brakes were not working, luckily I was in a 60 miles an hour zone so I had to just let the vehicle come to a gravity stop. To turn off the engine and start it back up again. 2nd incident: when driving the dash lights turned off and on like flickering on and off and all the gauges mentioned above did not work, and brakes did not work. This is very scary! All power in the truck is lost while driving and braking issue!

Service trailer brake system appears and my trailer brake information doesn’t show up on the dashboard when I try to manually engage the electric trailer brakes.

The contact owns a 2019 Chevrolet Silverado 3500. The contact received notification of NHTSA campaign number: 21V496000 (Equipment) however, the part to do the recall repair was unavailable. The contact called the local dealer who stated that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified but, no further assistance was provided. The contact had not experienced a failure. VIN tool confirms parts not available.

The contact, who owns a 2019 Chevrolet Silverado 3500, reported an incident that occurred while driving at approximately 35 MPH. A semi-truck, backing out of a warehouse across three lanes, collided with the driver's side of the contact's vehicle, causing damage to the entire left side. Despite the impact, no airbags were deployed. The collision exacerbated the contact's existing lower back and spine injuries, necessitating medical attention and ongoing physical therapy. A police report was filed following the incident. Although the vehicle was not towed, it was taken to a collision center, which determined that repairs could be made as the frame was not damaged. The contact consulted with the dealer, who was unable to confirm whether the airbag sensors had activated or failed. The manufacturer has not been informed of this potential airbag system failure. The vehicle's mileage at the time of the incident was approximately 63,000.
