Ongoing observation where the 10L80 equipped often shutters or struggles to determine the appropriate gear, often hesitating on acceleration. This has caused numerous scares when entering onto roadways. This has been a recalled issue on 2020-2022 models, but the issues persists with this year model (2024). The dealer has said it is a common experience among owners and expects a recall, but has said they can do nothing otherwise until then. The transmission has been properly cared for and serviced, following the GM recommended maintenance interval.

Loss of motive power due to engine failure post recall remedy
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V‑274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V‑274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GMâs recall remedy for Recall 25V‑274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V‑274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V‑274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

What 2024 Chevrolet Suburban owners say
Most recent owner complaints, unedited.
Persistent, intermittent total audio cutout disabling critical crash avoidance alerts. Failure Summary & Safety Impact: The vehicle experiences intermittent, complete failures of the audio system across all sources. When this failure occurs, all audible safety warning chimes are completely silenced—including Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, and Park Assist. This places occupants and other road users at immediate safety risk, as the driver receives no audible warning prior to an impending crash or hazard. Diagnostics & History: The issue first was brought to an authorized Chevrolet dealership for inspection and repair multiple times (first on April 29, 2026) and has not been remedied. They even replaced the radio system (through which all audio is routed) and this did not fix the issue. The vehicle remains in its original condition and is available for inspection upon request. There were no dashboard warning lamps or error messages displayed prior to or during the failure.
Driving our 2024 Suburban, 6.2 L engine, on a 2-lane highway in southern Utah, traveling on cruise control at 70 mph, felt 2 hesitations (jerking movement), and turned off cruise control. Immediately after, heard knocking/thumping sound in the front of the vehicle, followed by a whining sound that got louder. Immediately found a turn-off from the highway, pulled in, and engine died while vehicle was still in motion. Attempted starting again and would not start. People stopped to help us and tried to jump vehicle without success. Suburban was towed to a Chevy dealership and we were told the Suburban's engine seized. In researching this issue, we came across the federal safety agency's investigation case EA26005. Our VIN does not fall in to this recall.
Radiator was cracked and leaking at 42,000 miles. GM is well aware of the known failure, but has failed to issue a recall
Subject: Formal Safety Complaint—Cracked 22-Inch Polished Aluminum Wheels on 2024 Chevrolet Suburban To Whom It May Concern: I am submitting a formal complaint concerning repeated failures of the original 22-inch polished aluminum wheels installed on my 2024 Chevrolet Suburban, which I purchased new. Two wheels have cracked without any known impact, collision, road-hazard event, or other incident that would reasonably explain the damage. The first wheel cracked at approximately 25,000 miles. Tire pressure began dropping unexpectedly and ultimately fell to zero. The wheel was inspected and replaced by a dealership in Cincinnati. A second wheel later cracked and caused another sudden loss of tire pressure without warning. During that incident, I experienced difficulty maintaining steering control, creating a serious risk of a crash and injury. The second wheel was inspected and replaced by Tire Discounters in Lebanon, Ohio. The recurrence of substantially similar failures raises concern that the wheels may contain a material, manufacturing, or design defect. Aluminum wheels should not crack during normal operation in the absence of impact damage. A sudden loss of tire pressure, especially while the vehicle is moving, presents an unacceptable safety risk to the vehicle’s occupants and other road users. I respectfully request that Chevrolet and General Motors promptly: 1. Investigate these wheel failures as a potential safety-related defect; 2. Arrange for a thorough inspection of all remaining wheels on the vehicle; 3. Replace any affected wheels at no cost to me and review reimbursement for related expenses already incurred; 4. Confirm whether similar complaints, technical service bulletins, special coverage programs, or recalls have been identified; and 5. Provide a written response explaining the findings and proposed corrective action. I can provide the vehicle identification number, purchase documentation, mileage records, photographs, inspection findings, r
While driving down a two-lane blacktop road at 70 MPH (the posted speed limit) the engine, a 6.2 L L87 with a little over 15,000 miles, grenaded and seized. At the time I recall a warning message that said something like "engine shutdown". Fortunately the electronic transmission self-shifted into neutral so the car could coast to a stop. Had it not done this a loss of control would have been likely at this speed. The vehicle was towed to the local Chevrolet dealer in Bozeman, Montana (Resseler Chevrolet) where it was confirmed the next day the engine had seized. The dealer is currently replacing the seized engine with a replacement long block. The dealership currently has the engine and is planning to ship it back to Chevrolet or GM for tear down and inspection. They are also replacing the radiator and all coolant hoses as a precaution. Two weeks prior I took the vehicle to the same Chevrolet dealer complaining that on one day the engine shut off four times within 1 mile. Each time it displayed a warning message that said "restart engine", which it did each time. I also complained about a ticking noise that began in the engine at 12,000 mile. The dealer reported that the engine sounded fine and that they could not reproduce the engine shutting off on its own. This engine was NOT part of the large L87 recall. At time of purchase I was told by the selling dealer (Kendall Chevrolet in Maryville, Washington) and the local dealer (Resseler) that the engine was assembled after assembly line procedure were put in place to avoid the same issues as the recall engine. I've been and engineer for 46 years. The problem with this engine is not the assembly line, it is the never before used tight moving component tolerances and the water thin oil demanded by the manufacturer. The design shortcomings are compounded by systems such as cylinder deactivation and auto stop that significantly acceleration engine component wear.
Vehicle brought to Chevrolet dealer for recall# N252494000 at 27,626 miles. Vehicle passed inspection and oil replaced per recall. Despite engine passing and recall complete the engine failed at 29,861 miles requiring an engine replacement which was provided under warranty. The failed engine was taken by GM.
This an addendum to my original submission. Took my 2024 Chevy Suburban the the dealership XXX, my engine making unusual noises. Due to the severity of the sounds vehicle was towed to dealership in [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Initial indicators lead to engine failure as a result of defective part internal to the engine.
Transmission faulty, loud, clunky and hard shifting! Service transmission now alert and code P0747
