What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Chevrolet Silverado Lt, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

What the reports in each category say, in the owners' own words
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
Less than 33,000 miles the transmission thermostat cause the transmission to overheat. The dealership replaced thermostat and fluids. Then less than 100,000 miles same scenario and transmission goes out. Before it went out it had hard shifting and the obvious shutter at low speeds. Into my second transmission and same thing again!
Since I purchase my 18 Silverado the transmission has ALWAYS had a shift lag. On interstate especially it has become dangerous. I’ve almost been rear ended a few times bc it won’t shift properly. Even with the proper lane change habits the lag and uneven shifting has almost got me killed. Early on when I got my truck (est 2019) a dealer replaced some of the lifters in my engine. I spent over $40k and have even had to replace stereo because it died. I’m disabled I can’t afford to have major repairs while still making payments. Someone needs to hold Chevrolet responsible. I’ve read enough comments from people who have one and their complaints are the same. Is anyone looking into this?

From owner reports, verbatim
Since purchasing the vehicle in April of 2021, there have been significant issues with the audio system. This was noticed before the first payment was ever made. We had a “Act of God” claim made on the car for a tree falling on the windshield around this time. It was mentioned to the collision center at the time, but it was dismissed. The display will not work, gps system fails, it continuously changes settings and functions, etc. I can see where you would not consider this a safety issue, but I can argue otherwise and effectively, and would be happy to do so. This is a manufacturer issue. I have been made aware by several aftermarket companies that they have had to replace many of these components for similar issues, the dealership where we bought our vehicle literally told me that if I replaced it factory brand that I would have the same issue later down the road, and many acquaintances that have had to replace their audio systems for once again similar issues. This is just in one general location. If there are this many issues with one piece of equipment, there is absolutely no doubt that there should be a recall placed on these models. We purchase vehicles with the expectation that they will work. It is asinine and unethical to know of an issue and not correct it accordingly. We have purchased many Chevrolets in previous years, with an issue this persistent and without correction this may be the last Chevrolet we buy, which is a shame since it is an American company.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
