The 2018CHEVROLETSILVERADO LT carries 5 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2018 SILVERADO LT is power train with 2 filings, followed by engine (1) and electrical system (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 57 investigation files overlapping the 2018 SILVERADO LT, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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. Iâve almost been rear ended a few times bc it wonât 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. Iâm disabled I canât afford to have major repairs while still making payments. Someone needs to hold Chevrolet responsible. Iâve read enough comments from people who have one and their complaints are the same. Is anyone looking into this?

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 âAct of Godâ 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 on
