The truck when put in parking it still roll forward a little bit. Back up camera can’t not see during night time. Dealership stated they will not solve that problem and tell us to do manually by turn around look back. The suspension really bouncy but the tech stated that is normal. Spoke to other 3rd party tech they said that not normal at all.
NHTSA complaint #11758448 — an unverified report by a vehicle owner.
I am retired and have always bought GM vehicles which are taken care of with required oil changes etc. This one I have only owned 25,000 mi each year (I have owned two years). So, when purchased it has high 50,000 miles not sure of exact, and it has only been driven 2 years. When calling escalation at GM, they act as though it doesn't matter and too bad. 110,000 miles and the truck needs a new motor. This is what we are told and 10,000 more than the initial 1500 to tear it down. This truck is not broken due to us, this is a problem with the manufacturer and the responsibility needs to be addressed. My husband has a heart issue and he almost didn't make it home. I'm not accepting that nothing be done, since next we need a lawyer and a media appointment. This isn't right when you see thousands of people with the same GMC Sierra trucks online with complaints of the same valve and motor issues. This needs completely replaced and not by a customer, by the manufacturer. How can 1500 people new wrong on one sight stating the same as we have had. This person who is responsble for reporting and making sure we are safe needs to be fired. I am writing my representatives, senators etc to let them know this is going on. No one should pay for the mistakes of bad engineering. PERIOD.

While coasting down or under very light acceleration between 12-20 mph the vehicle has a shudder like driving over a highway rumble strip. While cruising on the highway at 65+ mph, the vehicle has a light shudder or vibration. Vehicle has been checked numerous times for wheel and tire inconsistencies. Brake pads and rotors have also been replaced with no change in issue. Headlights daytime running light changes color from bright white to purple during warm weather. The vehicle has been to 3 different GM dealerships and they acknowledge the issues but do not provide a resolve.

The contact owns a 2019 GMC Sierra 1500. The contact stated that the trailer lights flashed intermittently while the vehicle is turned off. Additionally, the contact stated while driving with a trailer hitched to the vehicle, the messages "Trailer Disconnected" and "Trailer Connected" were intermittently displayed, and the running and marking lights were inoperative. The contact related the failure to GM TSB Numbers: 20-NA-198 (Trailer Running Lights Shut Off Due to Excessive Load on the Running Lamp Circuit), PIT5747B (Diagnostic Tip - Trailer Lighting Complaints with Trailering App RPO U1D) and N192213550 (Service UpdateTrailer Integration Module Software Error). The vehicle was taken to an independent mechanic, where it was determined that the failures were due to a wiring or software failure.

I am writing to express my significant concerns regarding the recurring issues with my 2024 Denali 6.2, which has been subject to multiple service visits since reaching 7,000 miles. Despite these visits, the underlying problem remains undiagnosed and reoccurs shortly after I retrieve the vehicle. Following the second oil change, the engine developed a persistent ticking noise. Over the past 13 month, I have invested over $200,000 with your dealership in the past 5 years!. My truck was recently held for two weeks for service. After I lodged a complaint, the General Manager suggested I seek service elsewhere. This recommendation was made after I responded to an email stating that, following the completion of repairs to the headliner, third brake light, and brakes/rotors, I would no longer be utilizing Crain's services. The headliner sustained water damage due to improper installation by your technician, and fingerprints were also evident. I firmly believe in transparent communication regarding service progress, which was notably absent in this instance. Both the General Manager and Service Manager deferred responsibility, instructing me to contact GM directly, only for GM to inform me that direct contact was inappropriate. This resulted in a continuous cycle of unaddressed concerns with the service manager. Currently, I am operating an $80,000 vehicle that has incurred damage from a technician and exhibits a ticking engine. Furthermore, the driver's side mirror, which was previously replaced due to shaking at highway speeds, is now exhibiting the same issue, despite a technician's assertion that this is normal. I also note that my brakes, with over 89% remaining, are beginning to squeak, which your team claims is normal. This assessment is difficult to accept.

The backup camera in the dark on this vehicle is unusable. Someone will eventually run someone over. I have added brighter lights everywhere on the back of the vehicle and the camera is still useless at night. The dealer told me it looked fine to them (they checked it in a lit garage). There are hundreds of complaints across all forums.

While driving in the rain, the windshield wipers were on the highest intermittent setting and the high beam headlights were also on, automatic highbeams were not. The high beam lights dimmed to low, and the windshield wipers stopped in the middle of the windshield in the middle of navigating a sharp right hand turn at 35mph. The wipers stopped for approximately 30 seconds and then resumed operation. When the wipers resumed operation, the headlights also turned back on high with no input from the driver.

On August 3, 2025 I was on the road enroute to my residence. With no warning my 2024 GMC Sierra 1500 SLT engine quit. We heard a popping sound and the entire vehicle shuddered. I took safe control of the vehicle. As I intervened I noticed that the dash warning lights were lit. Almost immediately the warning lights went off and the engine restarted on its own. We were startled and extremely concerned about what had just happened. This was the first problem we encountered with the truck. I contacted the DeLuz Chevy garage in Hilo for a follow-up appointment.

Backup camera is not usable at night, you cannot see anything on the camera unless it is a brightly it area. This causes safety concern for people and property. Dealer confirmed no issues with the camera and that is how it is. Had to add external light to ensure I could see at night.

OTA update GM N25-250380 caused significant problems. Blinker tone and other safety tones are erratic. Infotainment system is erratic. Constant reboots while driving causing distractions. Camera screens will freeze on screen while driving down interstate. It may be affecting other systems as well since everything is erratic and buggy now.

Headlights on this vehicle, since purchased, have not cast enough light in order to see in unlit backroads, or extrememly dim areas. I have to drive with my brights on constantly, in order to get enough light thrown onto the road, for the left and right sides, as well as the front. These were not working well since purchase. I took my child to a friends house in rural PA, and I literally could NOT SEE THE street signs, let alone far enough down the road. I nearly hit a stone wall.. My eyes keep asking to see more, but truck does not produce enough headlight. I even went to the eye doctor, after that situation, thinking it was my vision dimming, but was told I have 20/20. There needs to be a formal recall. I am not the only one complaining about these HORRIBLE projection headlights. To replace these headlights would cost over 1000K, out of pocket, which is not something I should have to fix. I am complaining now, because with the light getting darker earlier, am noticing how lousy driving at night really is.. and honestly, being BLINDED by oncoming LED's , without having proper headlights on my truck in order to see when blinded, really [XXX]. Please address these [XXX]. Make headlights great again! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The entire instrument panel is blacked out. I can not see the speed, how much fuel and no waring lights etc. The screen flashes between black and dark blue and there is a repetative "ding" that I have no idea what is caused from since I can not see any warning lights, etc.This puts me and others at risk due to not being able to see any functions for operation of the vehicle, the speed or any indicator lights of vehicle issues. The dealer has seen the truck, and informed me that this is a known problem and they would have to order parts. According to the service department, parts for replacement will be covered under warranty/recall and they have been on order. It has been 3 weeks and they have no knowledge of when the parts will be in to make repair. There was no warning on this problem, the panel just went out.

When in a dark area with little to no lights the backup camera is unusable. The taillights/reverse lights do not put off enough light to provide the camera with the lighting it needs to see behind the vehicle in dark situations. If I am in an urban area with a lot of light pollution the camera works fine, but not when I am in a rural are with no lights.

The reverse lights don’t illuminate camera when you’re in a dark parking lot or area. If and when camera is relied on for reverse, you wouldn’t be able to see a person or anything else. It’s a lighting problem. When you are in an area that is lit (dealer parking lot) you can see fine. I also own a 2014 Chevrolet and camera works fine in dark and lit areas.

Back up camera is almost useless in very dark situations. Back up lights on vehicle wash out the view and all you can see are the red marker lines. Needs either brighter back up lights or a better camera definition. You cannot see a children's bike or other things while trying to back up.
