EXTERIOR LIGHTING
Intermittent issue with entire dash lights and radio lights going either fully out/off or extremely dark. Adjusting dimmer does not correct the issue. Affects driver safety due to acute driver distraction while trying to correct, and disables driver warning lights and all information systems, including towing related warnings (transmission temp/coolant temp, etc) Dealer advises to bring it back when it is occurring, but occurrences are not predictable, nor do they occur on a regular basis. Cause is unknown, but since dimmer switch does not correct this issue, it is the probable cause.

SERVICE BRAKES, HYDRAULIC, ELECTRICAL SYSTEM:12V/24V/48V BATTERY
The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, the battery was draining quickly and was replaced. The vehicle was taken to the dealer, but the dealer could not duplicate the failure. The vehicle was then taken to an independent mechanic and diagnosed with brake system failure. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the dealer for diagnostic testing. The failure mileage was approximately 13,000.

POWER TRAIN
Hard shift on take off from 1st to 2nd gear and while driving around random hard erratic shifting. Feels like pickup is getting rear ended. Have take in to Gregg Lair in Amarillo TX and they have reset shift points to no avail. I talked to head service writer and he stated that GM had a problem with their transmission but did not have a remedy for them. He advised to drive for about 3,000 miles and we have and still have the issue. We have been back multiple times and Gregg Lair states that it is still in learn mode after over 10,00 miles. I am a mechanic by trade and in my opinion there is a design flaw with the transmission and/or they have the wrong transmission fluid for the design.

The 2019 GMC SIERRA I own shifts extremely hard from a stopped position or when changing from reverse to drive. The shift is so forceful, that it feels like I have been struck by another vehicle. The overall feeling is that the vehicle is not safe to drive and it is not a reliable mode of transportation. The delayed shift, vibration and jerk, makes this vehicle a hazard to drive, as the ability to predict the issue is impossible. There are no other warning lights, or messages prior to the error. Online forums show this to be a known issue.

ENGINE
My 2019 GMC Sierra was traveling on the highway at 70MPH. The oil cooler line detached, and the truck shut down telling me to get over now. There was oil everywhere. I am shocked it did not catch fire. there was also 7 quarts of oil on the highway I called the dealer, and they are well aware of this problem. They were sorry but there is nothing we can do for you. They told me they do 1-2 oil cooler lines a month. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

VEHICLE SPEED CONTROL, POWER TRAIN
Transmission jerks, slams, forces a feeling of being rear-ended, delayed acceleration with sudden engagement causing uncontrolled acceleration. I've had it looked at every time I've taken it into the dealership for regular maintenance. They haven't been able to reproduce it as it only happens once, first time after not driving it for a while. No warning lamps or messages ever appear.

ENGINE
Every time I start the engine I get loud ticking noises. This is Lifter noise! I took it into the Dealership and they said the noise was normal. GM is known for having this Lifter problem in the heads. This can destroy my engine, causing premature wear on the lifters themselves.

ELECTRICAL SYSTEM, SERVICE BRAKES, ENGINE
While driving on a two lane road I proceeded to pass a slow moving vehicle, after accelerating from 45 MPH to 60 MPH my Check Engine light, Service Electronic Stability Control (ESC) and Service Electronic Brake System lights illuminated on my display. My RPMs increased before shifting gears and I noticed a significant loss in power. Thankfully there was not an accident when the incident occurred; however, if an oncoming vehicle or bad weather it could have been a different outcome. I took my vehicle to a GMC dealer to diagnose the issue where I found out my lifters for my valves are bad and my fourth cylinder is inoperable along with a bad CAM. A new vehicle at 65K miles on it should not be having mechanical issues that can pose a danger while driving, putting others and my safety at risk. GM needs to reevaluate the products and materials their using to build engines to ensure there are no flaws starting with the valve lifters.

VEHICLE SPEED CONTROL, ENGINE, POWER TRAIN
While towing our trailer, truck went into reduced power mode, regen message displayed; check engine light came on; loud bag occurred and hissing from under the hood. Truck slowed to 3 mph so we pulled to shoulder and turned the vehicle off. Truck had blown the hose off the the turbo. We reclamped and restarted. Displayed check engine light, reduced power & regen message to keep driving however truck wouldn’t go over a 3mph crawl. Truck lost all power, everything shut down and wouldn’t restart. No dash lights, no error, no crank, no power. We were dead on the highway in the truck lane while towing. This Truck goes into reduced power mode every time it tries to regen and we have had it to the dealer multiple times however, the problem continues to get worse. When it does regen, sometimes it takes hours. Dealer says needed a manual regen & that is their solution. Yet problem persists.

The problem is still pending , At the dealer, and General motors has been notified . Case 9-6893265248, General Motors Product Assistance Claims (PAC) There has been a police report filled with local officials, I don't think the dealership has inspected , Buy recommendation of GM, since this is none accident related to the air bag system going off randomly, Very freighting to me and my family. No warning lamps no indication of anything wrong with the vehicle, prior to incident, And one of the boys could not exit the car due to the seat belts being cinched down on him during the air bag explosion. Incident happened 8/22/2021 at about 10:15 to 10:30 AM A week latter we are still waiting on answers from general motors as to what happened , This vehicle has never been in an accident , And we have all the service records from the dealership , The only place it has been serviced, GM has download data from the computers, And we have asked for copies of those data files as well, We do have all the service records as well should you need them.
