ELECTRICAL SYSTEM
My truck’s battery is dead after sitting for a few days. There is a manufacturing deficit causing parasitic draw. This is a safety issue because it leaves us stranded after parking the vehicle for a few days. The General Motors dealership refuses to do it anything about it. They claim it’s normal.

VISIBILITY/WIPER
Started my truck and started driving. It was a very foggy night with lots of mist in the air, so I turned on the defroster to clear fog/dew from the side view mirrors. About 10-15 minutes later I hear a very loud pop inside the truck. It turns out my rear driver side window was completely exploded/shattered. This seems to be a known issue in these trucks.

SERVICE BRAKES
At low speed (5 mph or less), my GMC truck looses brake pedal resistance and I have to mash the pedal hard to stop.... very dangerous when in traffic, parking lot or pedestrians crossing in front. This needs immediate attention. No warning lights on dash. After researching this issue online I discover there are many youtubes and complaints about this apparent brake vacuum pump problem). I also see where there is a recall of over 3.5 million Chevy/GMC vehicles (recall #s N202300860 and N192268490) for this exact low speed brake pump problem. My GMC truck falls within this recall (GMC Sierra LD between 2014 and 2018). But when I check my VIN # on the NHTSA website, it states no recall. How can this be? It clearly is the exact same issue. Please explain.

EXTERIOR LIGHTING
During winter/snow driving snow accumulates on the headlights and causes a partial to total loss of visibility. This has happened multiple times during winter months. Cleaning the headlights requires exiting the vehicle in a potentially dangerous situation. This may occur after every few miles or less depending on the conditions.

STRUCTURE:BODY
I have a 2011 GMC Sierra Standard Cab pickup truck. I’m a disabled veteran and have this as my primary vehicle. The frame has a huge hole that developed and will need repair. The frame is rotted and soon will not pass inspection. The truck looks brand new but Engin compartment, frame and tow parts have rotted. I had the leaf spring separated from rotted frame on the highway. I swerved and almost died. GMC must replace the frame to make this right. Soon I will have no truck after giving GMC so much money. It’s criminal what they have done.

SERVICE BRAKES, ELECTRICAL SYSTEM
I purchased my 2018 GMC Sierra 1500 pickup truck new in 2018. To date it only has 28K miles on it. I have never used the trailer breaking system that it came equipped with. On 12/24/22 we were traveling to a family function for Christmas. The "service trailer break system" warning message came on and the chime chimed continuously until I got to my destination, about an hour away. This chime was very distracting and there was no way to turn it off. After arriving at my destination I turned the truck off hoping it was just a fluke. When I started the truck back up the "service trailer break system" warning light and chime continued. It continued for an hour on my way home. Again, this was very distracting and I was unable to focus 100% of my attention on the road and my driving. Thank fully I made it home okay. On 12/27/22 I took the truck to my mechanic to have him take a look. He said he has heard of this issue with these pickups. His diagnostic confirmed that the trailer breaking switch (on the dash) was functioning properly but said that the chassis control module was likely the culprit. He replaced the control module and it had to be programed by a factory technician. After this part was replaced the warning light or chime does not come on anymore. I have the defective part for inspection and the bill totaling $1191.86 for the repair upon request.

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
My 2016 GMC Sierra 1500 (5.3L 8-speed). When on the highway or in the city when the truck is changing gears it has a shake almost like hitting small bumps on the side of the road. I have several friends and family members with the same model truck and have spent thousands of dollars to fix the problem by modifying the whole truck. Is there anyway a recall could be made since it has to be a huge issue with all models with the v4 mode? I brought it to a transmission shop due to GMC dealerships being booked for weeks..the receipt is attached! They said the fluid was burnt and changed it but need new torque converter!

ELECTRICAL SYSTEM, VISIBILITY/WIPER
Rear defroster (with sliding rear window) thermal events with arcing and hissing, smoke smell present. Matches the same description as provided in document N192265660. GM will not cover my vehicle because it was not delivered to a dealer in any of the states listed in the document. There is evidence in the vehicle of thermal events, however GM wants me to pay $1000-$1500 for a new rear sliding window.

POWER TRAIN
Truck was placed in Park on an inclined road. Exiting truck, truck started to roll backwards. I was struck and right foot was run over by Driver's side front tire and knocked down. I was wearing composite toe shoes which enabled me to get up and run after the truck, trying to stop and control the truck a second time. I was hit again and thrown off the side of the road into a briar patch. Truck continued to roll backwards and off the road into the woods. Upon investigation, two separate County Deputy Sheriffs confirmed that the truck. when it came to rest, confirmed the truck was still in the Park position. Truck had to be towed out of a ditch in the woods. I sustained moderate injuries, but thankfully was not catastrophically disabled. This should be investigated thoroughly, so that no other person(s) is injured or dies as a result of this defect.

SERVICE BRAKES
I purchased this 2018 GMC pickup in May 2021. Starting in Nov 2022 I started getting a sporadic SERVICE TRAILER BRAKE SYSTEM warning light and chime. I have never towed a trailer using this trailer brake system on the vehicle, but the warnings come on sporadically. I have done some research and found this is not an isolated case as others have reported the same problem. Some owners have replaced the dashboard controller at their own expense, however this is now a well documented problem that goes beyond an isolated case. This is a defect of the trailer brake controller and should be recalled by GM at GM expense. It is a hazard to driving when the visual and audible chime come on sporadically. It's a distraction to safe driving and requires immediate intervention. I did advise my local dealer of the problem when the vehicle was serviced Dec 2022, however they did not have a technician available to work the problem. So I continue receiving the visual and audible warning every time I drive the vehicle. Please highlight this problem within your organization for a possible safety recall.
