Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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!”
NHTSA complaint #11677598, filed 2025-07“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.”
NHTSA complaint #11585338, filed 2024-04“The electrical connector vibrated loose at the injector. The mechanic said he has seen this happen before and GM said its because those motors vibrate excessively. It caused my vehicle to run in reduced power mode. In that mode it was lurching forward uncontrollably and it felt like the transmission was banging. What damage will that alone cause in the future? Also, if GM knows there is an issue, why isn't it fixed? Why is the consumer responsible for poor engineering or design flaws? It isn't normal wear and tear or neglect on my part. …”
NHTSA complaint #11522066, filed 2023-05“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! …”
NHTSA complaint #11696384, filed 2025-10“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.”
