STRUCTURE:BODY
While driving on Interstate 10 at 70 mph the upper section of the front grille broke off. After the part broke off it contacted my windshield before continuing to fly off behind him. Not only putting me in danger but also anyone traveling behind me. From online research the is a recall for this truck except the 2022 models after the same thing happening.

engine recall 6.2 L-87 , after Pico scoop Test, which my truck passed, its using 2 plus quarts of oil per 1000 miles, the dealer has it and is saying they can find nothing wrong per the gm tech that is telling them to check this and that. Ok, oil is going somewhere, I want the motor replaced , they want to continue the oil consumption test, my thing is wasting my time to continue driving and bring back to it back for a low oil reading, Its not gonna fix its self by driving it. I understand gm wants to figure out why, but it should not be at customers time , replace the motor all ready, something is wrong. the first 1000 miles after a oil change and they put die in the oil to check for leaks. When They check the oil level friday 02/06/26 the oil did not read on the dip stick.

STEERING
This letter serves as a formal notice of concern and demand for accountability regarding the 2009 GMC Sierra LD, VIN [XXX] , owned by [XXX] . There are numerous documented complaints and safety investigations concerning premature tie rod failure in 2009 GMC Sierra models. While the 2009 model year may not have been subject to a sweeping, industry-wide recall specific to tie rods in the 1500 series, it is undeniably and consistently associated with premature steering component failure — including both inner and outer tie rods. The refusal to proactively address this defect, assign a broader recall, or take ownership of the recurring issue reflects a troubling disregard for consumer safety. Documented and Reported Issues Include: • Premature Wear: Tie rods becoming loose or failing between 50,000–100,000 miles, resulting in steering wander and excessive play in the steering wheel. • Clunking/Knocking Noises: Audible front-end knocking at low speeds, a well-known symptom of failing tie rod joints. • Severe Safety Risk: Instances where tie rods have separated or become dangerously compromised, directly affecting steering control. • Uneven Tire Wear: Excessive inner or outer tire edge wear caused by steering instability. • Recall 14V-246000: A related recall acknowledging improper tightening of tie rods where they thread into the steering gear rack — a defect that could cause separation and loss of steering control. The common symptoms — steering vibration, looseness, clunking when turning, and vehicle pulling due to misalignment — are not minor inconveniences. They represent serious safety hazards that endanger drivers, passengers, and the public. It is unacceptable for GMAC and General Motors to minimize or compartmentalize this issue when patterns clearly demonstrate a systemic steering component weakness in this model year. The presence of Recall 14V-246000 further demonstrates that the manufacturer was aware of tie rod-related risks ! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

SUSPENSION
I am writing to formally express my dissatisfaction regarding a significant safety and reliability issue with my 2020 GMC Denali. Specifically, the vehicle is experiencing premature wear and imminent failure of the front ball joints. I expect the suspension components of a premium Denali-trim vehicle to last significantly longer than the 37,061 miles currently on my odometer. Industry standards typically place the lifespan of these components between 70,000 and 150,000 miles. Technical Details of the Failure: The vehicle is currently exhibiting the following symptoms of accelerated ball joint degradation: •Excessive Vertical and Lateral Play: Inspection reveals play in the right lower ball joint that exceeds the manufacturer’s maximum allowable wear specifications. The left lower Ball Joint is starting to have a small amount of play, according to the technician

I waved down a police officer and he kept me safe from cars hitting from behind.Come to find out it was the bearing rod and now I’m getting my engine replaced.

ENGINE, POWER TRAIN
The engine has been burning oil since purchased but really highlighted when at 47k miles I got a dashboard message saying “reducing power to engine” I checked the oil and it didn’t register in dipstick. I added 3quarts of oil to show up on dipstick. When I changed the oil which I did at my own garage only 2.5qrt came out including what was in filter. It’s since take an average of 2.5qrt between oil change at 7500. Also the transmission is slipping which happened after warranty expired at about 69k miles and I don’t want it to repair or repair until gm fixes these issues which they know are problem in2020-2021 models but they haven’t addressed it. My truck has been serviced at the dealership except fo 3 oil changes. The issue are noted but the answer is car burn oil typically between changes. Yeah they do if it was 20yrs old not 3yrs. The issue lies with GM. It’s Needs to be addressed.

At 22,000 miles I experienced issues while driving on a 150 mile trip. We frequently take this particular drive. We choose to driver later in the evening to miss commuter traffic. This even we pull over for a late dinner and hear a loud ticking noise while the the truck seems to lose power. I turn the vehicle off and start it again and its worse, it barely idols and shuts down. I'm in a parking lot and drive down the block to a gas station where serves only gas and no mechanics onsite. I turn off the car and wait 5 mins and restart, same results but this time all the warning lights come on. We end up finding a hotel and in the morning i find a Chevrolet dealership down the block, I ask if I can take it in, there the advisor connects to my obd port and says there are many issues and needs to see a mechanic. I manage to get it towed 80's to the original dealership. Advisor says the engine is bad and replaces it. Now my vehicle has 38,000 miles and I run into the same issue, loud ticking sounds and low power. Immediately I drive it home and the next day have it towed to the dealership to have it looked at. The advisor said during their analysis they saw metal in the air filter so another engine has to ordered and installed.

ENGINE
My truck supposedly passed the initial recall for the 6.2L GM engines. AT THIS TIME THEY CHANGED THE OIL AND SAID THE ENGINE WAS FINE! 5 months and one oil change (performed at the same GM dealership using the new recommended oil) my engine seized up while driving approximately 55 mph in rush hour traffic. The engine made a banging and clanging noise and lost power approximately 1/4 miles after the initial noise. This almost caused two accidents as the traffic had to come to a sudden stop, That’s engines are extremely dangerous to both the owners and the driving public on the highways alongside them. p the failure of the engine put me in a highly dangerous situation. This “oil” Fix is not doing what GM is saying it will do. I was told yesterday that my vehicle will need a new engine and radiator. This is simply dangerous and it makes for a horrible financial situation with the truck already needing a new engine.

I remote started my truck. I got in about 5 minutes later. When I shut the door the rear window, passenger side of the power sliding window blew out. GM says my VIN is not affected by the recall but my truck shows that it should have been part of the recall or customer satisfaction program. N192265660 Rear Window Defroster Thermal EventS

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The front forward-facing camera module has failed, causing cruise control and driver-assistance features to become inoperative. Dealer diagnosis indicates the front camera must be replaced and recalibrated in order to restore cruise control and safety systems. This failure disables cruise control and driver-assist features that were standard equipment on the vehicle at purchase, resulting in a sudden loss of functionality while driving. The dealer has provided a repair estimate of approximately $1,150, including parts, labor, and required calibration, at owner expense. Based on similar reports from other owners, this appears to be a recurring issue affecting this model year.

54k miles. Crankshaft failure. Truck shut off and put in neutral while driving with no codes on dash. Got a text saying to service engine and transmission immediately. On a side note, it is bullshit that you can't put the truck in neutral to get it off the road. The dealership is also doing a great job covering it and offering a loaner.

The vehicle camera camera system is sometimes not available at startup and will not reset until the vehicle is allowed to sit for several hours. This prevents the backup camera, forward camera and side mirror cameras from providing an in-dash video of vehicle surroundings, which is especially critical for reversing direction or backing-up. Typically the camera will reset after sitting from a period of time. I have reported it to the dealer, but their position has been that since camera has always been working when I bring the truck in for service, is that there is really nothing they can do to correct the intermittent issue.

After a really bad cold snap noticed oil spots on my driveway, after further inspection noticed the oil cooler lines were leaking from the crimps. Got in contact with GM because there was a customer satisfaction program for my year model- N212326940- they told me it did not apply to my truck but it is a know issue, and now I’m having to come out of pocket for it.

My 2020 GMC Sierra 1500 experienced a premature transmission failure consistent with GM’s known 8-speed transmission defect. My safety and the safety of others were put at risk if/when the transmission occurs a temporary lockup which can/will cause the vehicle to stall on the highway, and potentially create a minor/major automobile incident if vehicle stalls. The vehicle was taken to dealership Capital Chevrolet Montgomery, AL where dealership technician diagnosed/confirmed the issue along with pictures of internal transmission failed components as well as recommended resolution for fix. The vehicle has been inspected by my out-of-pocket expense extended warranty company Endurance Warranty Services sub-contracted repair claims adjuster. No warning lamps, vehicle messages, or other symptoms of the problem prior to the failure were noticeable; the vehicle had multiple diagnostic scans prior to original sale and after sale to present no issues or trouble scans. the first issue appeared or was noticeable 12/08/2025. GM has refused action by asserting warranty expiration despite widespread knowledge of this defect. The vehicle has been out of service since December 8, 2025.
