EXTERIOR LIGHTING
Lack of illumination of headlights straight ahead. No light shines to the sides of the vehicle making it difficult to see left or right when negotiating a turn at night. I have put new bulbs in both sides the best money can buy at CarQuest with no improvement. The headlight lenses are not dirty or fogged over. It appears to be a design problem, and I have seen other people with this model truck complain about the same thing on some blogs. I contacted GM directly looking for information I can get on a possible upgrade, and they have offered not solution. I have had this issue with this vehicle since buying it used 4.28.2018

ENGINE
Complete engine failure confirmed by GMC dealership service technicians. Incident Details: On [XXX] while driving at approximately 45-50 mph on [XXX] , my vehicle suffered a complete engine failure without warning. This resulted in sudden loss of power, inability to accelerate, no warning lights, near-accident, and the need to pull over in unsafe conditions. This failure placed me and my son, as well as others on the road at risk of serious harm and has left me with no confidence in this vehicle’s long-term safety and reliability—even with an engine replacement.

The engine has blown for the 6.2L V8 Denali with 31,300 miles. I was told that this is happening on several of these engines. They told me it would be 3-4 months for repair as the engines are on backorder. I am not able to use a truck that I have purchased and am paying on.

Valve Body. While driving the vehicle, hard shifts occurred; the vehicle check engine light came on and stayed on while the vehicle went into limp mode. I was able to link to the GMC dealer. The dealer was not and would not inspect the vehicle at that time. I was told I needed to leave or return in two for inspection. The left vehicle was inspected the next day and determined as a value body. The GMC dealer found the part in another state and has the part shipped. I installed the part, had the GMC dealer search it, and performed a recall update.

ELECTRICAL SYSTEM
While driving on interstate transmission would “lock up” momentarily creating drastic drop in speed and unable to shift gears and accelerate. “D” would start flashing in dash board. Dealership said this is unrelated to current recall about rear wheels locking up from valve body failure and instead this is an electrical issue. Dealership also stated this is the 2nd truck in a week they have had come in with this issue. Almost caused accident on interstate with my family and I as a result of sudden drop in speed and unable to accelerate with multiple cars behind us.

There is a known defect by other consumers with the same year/make/model as mine that causes the radiator to leak. I replaced the original radiator about a year ago with a new GM radiator (84207654) and it’s now leaking as well.

The front chrome grill on my Sierra 1500 SLT has begun to detach, and there is currently a recall for this specific component on my vehicle. I took my truck to GMC Covert Bee Cave to get this recall and 1 other recall fixed, but GM does not have a remedy for grill. Not only does this pose a safety risk to myself, but I use my truck as a source of income by renting it out on Turo, and Turo has unlisted my truck from the app indefinitely or until this remedy is resolved. The paperwork I received from the dealership confirms GM has no remedy for the recall, and they sent me on my way without even offering a replacement vehicle. My truck is available for inspecting if you would like to see it. My safety and others safety is at risk if this recall does not receive a remedy or if GM does not give me a replacement vehicle in the meantime. No warning lights or any other systems can notify me if the grill is going to detach all the way, and I will not be able to have this source of income from Turo without the ability to have my truck relisted.

On 1 February 2025; I was stuck in the mud, in my pickup. As I was attempting to get out, my truck died. After several attempts to restart my truck; I was towed to my lake camp. Which located less than 100 yards away. Since it was no longer had a current warranty I contacted a mechanic. He arrived the following day and discovered that the engine was “locked up”. I had it towed to his shop, and he began to diagnose the engine. He has determined that the crankshaft is broken and 2 rod bearing are spun. He is currently checking for piston borehole damage. If no other damages are found, he will ordered repair parts and repair my engine.

ELECTRICAL SYSTEM
Infotainment screen not responsive to touch, will not reset and freezes with black screen message warning drivers to not take their eyes off the road. Because of the latent defects known to GM in the screen, it is impossible to reset the controls (the "OK" button will not clear the error message). The freezing and non-responsiveness and elimination of outside temperature display creates a driver distraction hazard trying to clear it while driving, and prevents the driver from being alerted to outside temperatures dropping below freezing. GM customer care refused to provide any assistance for the $1,045 repair charge quoted by the dealer and refused to acknowledge that this is an inherent vehicle defect well established, that already produced a service advisory and redesign of the defective screen. Problem has existed for quite some time, and infotainment issues were initially reported to dealer on 3/9/2015 (2 months after delivery) without adequate resolution.

POWER TRAIN
Transmission Light has been on & off for a month and half. Had it at dealer twice, dealer will not confirm a problem. Truck shifts and bucks between first and second gear. Makes stopping in traffic difficult as truck will surge and jump when down shifting while stopping. Took truck to AAMCO Transmission shop. Confirmed problem, no new transmission units or rebuild parts are available for the GM 8 Speed transmission. AAMCO is replacing unit with a used one. This is a company truck also have a second truck having the same issues with half the miles of this unit. In my opinion GM is aware of the issue in that with both trucks at dealer with same issue, they just send me off with no documentation so as to not have a paper trail. Also no new units available makes me believe that GM can not keep up with warranty replacements.
