ELECTRICAL SYSTEM, UNKNOWN OR OTHER
On 2 occasions now my tailgate has opened on its own. The first incident happened sometime after I got home from work for the night, when I went to leave in the AM my tailgate was resting on the garage door and had been scratched. The second time it happened I didn’t notice it while driving but when I went to close the garage door I looked back and saw the gate was open and partially sticking out of the garage. Nothing happened this time to put anyone at risk however there is damage to the truck and if it happened while hauling something could have come out and hurt someone or damage property. I have not brought it to a service center yet. No warning

POWER TRAIN
When the truck reaches approximately 50mph it is unable to shift into the next gears and then it's unable to downshift. The transmission will not go into neutral. The truck must be stopped and turned off, sometimes it will need to be restarted 2x before it's able to shift into first gear. The outdoors temperature was approximately 24F, transmission temp was 178F. The truck locked into 7th gear 6x in a row while the transmission was set to normal driving mode. There were no signs of transmission failure until the vehicle reached approximately 50mph, afterwards the check engine light illuminated, a warning stating "reduced acceleration drive with care" and "service transmission now unable to shift soon". The trucks RPMs were approximately 2500rpm while driving 45mph and would not go down because the transmission would not shift up or down.

POWER TRAIN, ENGINE, SERVICE BRAKES
I received a notice of a recall for a known problem with GMC transmissions. it is very well known that these transmissions lock up and cause problems with braking and can cause the vehicle to slide off the road when the tires lock up. it also causes hard shifting, which I have experienced. GMC said they will not fix the transmission, they instead will add a device to monitor the transmission, so when the transmission locks up and causes an accident, it will let me know that it was the transmissions fault!!! How is this legal? they will let me know that their transmission caused the accident after the fact? why not fix it? typical of government to do nothing about safety... and instead make laws that allow big corporations and government to make money off of peoples deaths!

Subject: Potential Issue Related to Recall N202314870 for GMC Sierra 1500 Problem Description: I own a 2019 GMC Sierra AT4 (VIN# [XXX] ) and have identified a potential issue related to the drive shaft. Although my VIN does not appear in the official system as affected by recall N202314870, the vehicle exhibits the following symptoms: 1. Unusual and consistent vibrations in the drivetrain while the vehicle is in motion. 2. Noises coming from both the front and rear differentials. 3. Concern regarding the integrity of the drive shaft, as these issues align with the details described in the recall. Given that this issue potentially affects the safety of the vehicle, I kindly request a review to determine if my unit should be included in recall N202314870 or any other related campaign. I appreciate your consideration of these symptoms for a proper evaluation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
I have a 2019 gmc sierra 1500 elevation. The dash indicated low oil with 60lbs of oil pressure. I stop park my vehicle and see there is a puddle of oil underneath my truck. It appears to be leaking (extremely high flow rate) from the oil cooler lines where the rubber has given way from the metal crimping. Apparently after calling the dealership and reading online there isn't any type of recal for this issue even tho there is a Customer Satisfaction Program N212326940 implemented for Alaska and Canada due to the cold weather climate causing the failure. I live in western Pennsylvania and currently had a cold snap of 11°F. The dealership wants me to pay out of pocket and take my vehicle in to get diagnosed for service , which also means paying to have it towed to the dealership since it is un-drivable . Then pay for the very obvious service and file to see if I can be potentially reimbursed. This vehicle has less than 70,000 miles on it and is outside of the warranty. However this is a reported common issue online and even through the service department in Zelienople Pennsylvania because the tech. Told me they have the parts in stock because they do alot of them when I was inquiring into the issue.

EXTERIOR LIGHTING
The reverse lights are too dim to provide sufficient viewing of the rear of the truck when it is dark outside and there is no other lighting. Almost nothing can be seen from the rearview or sideview mirrors, and the backup camera is rendered useless. GM changed the design of the taillights such that they are now sealed, which means owners cannot upgrade the reverse lights with stronger LEDs any longer. This lack of lighting is more than an inconvenience; it is a safety issue. This is a known issue and GM is well aware of it.

STRUCTURE:BODY
As I was traveling down the interstate at about 70 mph the front upper grille moulding flew off and almost hit the vehicle behind me. The clips that held this on the vehicle are very weak and this is happening to many of the same vehicles. Had I hit a car behind me there could have been significant damage, and luckily there was not a motorcyclist behind me. I did not hear any rattling or have any damage to the vehicle, this is simply a manufacturer's issue.
