Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2023 Chevrolet Suburban sits in the middle of the current generation’s federal-record arc. After the 2021 launch year posted 179 complaints and 12 recalls, reported defects dropped to 105 complaints and 4 recalls in 2022, then ticked slightly to 109 complaints while recalls fell to 3 in 2023, with investigations holding steady at 3. TSB volume also fell sharply from 1,166 in 2022 to 653 in 2023, while the 2024 entry shows a further decline to 559 TSBs, 36 complaints, and 1 recall. Engine-related complaints dominate the 2023 file with 42 reports, followed by “Unknown or Other” at 8, powertrain at 7, and engine cooling at 5; fire complaints are zero and crash complaints are one, though the data does not specify a common root cause. That pattern places 2023 as a maturing model year with a lighter recall load than 2021–2022 but still more owner reports than the newer 2024. For a used buyer, a 2023 Suburban looks like a reasonable choice: it avoids the launch-year recall spike and carries only three recalls, though any candidate should be inspected for the engine complaints that lead the file.
