The short list
Where the money goes wrong — and where it doesn’t.
✕ Years to avoid
The transmission year — the 8L90 at its loudest. 831 complaints, the most of any third-generation year, and the file is dominated by the eight-speed: a shudder you feel through the truck, surging, hard 1–2 shifts, hunting for gears, and torque-converter failures. Owners in the file quote $7,500 from a dealer and $4,670 for an independent reman; shudder onsets are reported as early as 20,000–22,000 miles, with replacements at 94k and 120k. GM's answer is a flush with a revised fluid, which helps many trucks — so ask for that service history and drive it at light throttle at 25–50 mph listening for the shake. The AFM lifter risk on the 5.3L rides alongside it, uncovered. One narrow bit of good news: a fuel-injector Special Coverage (N182198000) exists for 5.3L and 6.2L trucks — but only in 13 emissions states (CA, CT, DE, ME, MD, MA, NJ, NY, OR, PA, RI, VT, WA), so check where the truck lived. Verify the vacuum-pump brake-assist recall (19V645) and the control-arm weld recall (16V256, a 'do not drive' campaign).
The launch year — and the lifter design got worse. 1,033 complaints, the loudest Silverado in our data, and this time the engine is the story rather than the transmission. 2019 is the pivot from AFM to DFM: where AFM deactivated four cylinders, DFM can deactivate any of eight across 17 firing patterns, doubling the problematic two-piece lifters and running deactivated more of the time — mechanics say it fails more often and at lower mileage. In-sample failures land at 35k, 60k, 106k and 143k miles, described as a pop, then lost oil pressure at highway speed. There is no recall: a class action alleges the valvetrain is defective by design, and owners report being denied once out of warranty. On top of it, a Customer Satisfaction Program (owners cite N212326940 — a CSP is GM's quiet, free-repair program short of a recall) covers engine oil-cooler lines that leak and detach at the crimp, dropping oil pressure with no warning. Launch-year safety recalls are free but must show closed: a battery cable that can stall the truck or arc into a fire (19V888), a driveshaft weld that can separate (20V650), and a seat-belt pretensioner that can ignite the carpet (19V814).
✓ Years to hunt for
The best of the old body — the kinks worked out. 504 complaints, the lowest of the third generation, and the reason is the transmission: the 8L90 wave receded, mechanics say the kinks were mostly worked out, and the complaint file backs it up. What doesn't improve with the model year is the AFM lifter on the 5.3L — still a tick, misfire, power loss and a $3,000–$10,000 repair with no recall behind it, so cold-start the truck yourself and listen. Free programs to check by VIN: the fuel-rail bracket braze CSP (an incomplete braze can sever wiring to the fuel pump or the passenger-side injectors — reduced power, a remote fire risk) and the vacuum-pump brake-assist recalls (19V645 and 20V603, the latter specific to 2018 5.3L/6.2L trucks). Two carryover realities to price in: the A/C condenser cracks with no recall (about $1,000 out of pocket — look for the upgraded condenser's mark in its top-right corner) and the wax frame coating flakes, so salt-belt trucks rust around the fuel tank. Note the 2018 crew cab's roof-rail airbag inflator recalls were still expanding through 2026 (24V756, 25V432, 26V166, 26V325) — parts availability, not danger, is the usual sticking point.
The quietest year — and GM finally admits the lifter. 342 complaints, the lowest in the range, and only three recalls. But the newest year is not the innocent one: GM's clearest acknowledgment of the lifter problem lands here as a Customer Satisfaction Program for trucks with oversized engine lifter bores, where the remedy is a new engine — and a second program covers transmission pinion gears with low hardness, remedy a new transmission. 2023 also still shipped the older eight-speed on some trims, with harsh shifts and a class action to match. If it's a 6.2L, recall 25V274 (connecting rod and crankshaft, ~597,571 trucks, free inspect-repair-or-replace and a switch to 0W-40 oil) applies and must show completed. Also on the list: a low-brake-fluid warning software recall (24V674, free, often over-the-air) and a CSP for chip-shortage trucks delivered with heated and ventilated seats that simply don't work. A clean, VIN-checked 2023 is the strongest buy here — with the same cold-start listen as every other year.
Same year. Different engine.
One badge, several engines — the year’s verdict assumes the riskiest one. Yours might be the calm one.
Which engine is in the one you found?
Where the years split by powertrain — the V8s carry the lifter risk, the eight-speed carries the shudderThe volume engine — and the lifter that defines the truck. The 5.3L EcoTec3 deactivates cylinders to save fuel, and the lifters that do it collapse. Through 2018 it's AFM (Active Fuel Management, four cylinders off), from 2019 it's DFM (Dynamic Fuel Management, any of eight across 17 patterns) — and mechanics are unanimous that DFM fails more often and at lower mileage, because it doubles the number of the problematic two-piece lifters and runs deactivated more of the time. The sequence is a tick, then a misfire, power loss, and often a bent pushrod, a damaged camshaft, and metal through the engine: $3,000 to $10,000. There is no recall — only a class action (E.D. Michigan) alleging the valvetrain is defective by design, reactive warranty repairs, and owners reporting denials once out of warranty or after a repeat failure. GM's 2023 Customer Satisfaction Program for oversized lifter bores (remedy: engine replacement) is its clearest admission. Cheap prevention exists: a disabler module (around $150) keeps the engine in V8 mode. Cold-start every truck you look at, and listen. The same engine can also burn oil — owners report a quart every 1,500–2,000 miles, and GM calls up to a quart per 2,000 within spec.
The lifter risk plus a federal engine recall of its own. The 6.2L shares the AFM/DFM lifter story with the 5.3L — same collapse, same $3,000–$10,000 bill, same absence of a recall — and adds one all its own. Recall 25V274 covers roughly 597,571 GM trucks and SUVs from 2021–2024 (Silverado, Sierra, Tahoe, Yukon, Escalade) for connecting-rod and crankshaft manufacturing defects that put debris in the oil and can cause sudden, total engine failure — 'no warning, just died' in the complaint file. The remedy is free: inspect, then repair or replace the engine, and switch to 0W-40 oil. NHTSA has expanded its probe twice and is investigating failures beyond the recall's scope, and 2019–2020 owners report the same pattern outside it. On any 2021-and-later 6.2L, the recall must show completed by VIN; on an earlier one, treat sudden engine failure as a known possibility rather than a freak event. A fuel-injector Special Coverage (N182198000) also touches 2017 5.3L and 6.2L trucks — but only in 13 emissions states.
The quiet-running option with two specific weak points. The 3.0-liter Duramax inline-six skips the cylinder-deactivation lifter story entirely, which is most of why buyers like it. It has two named issues instead. Mechanics report a coolant-control-valve failure that is common on 2021–2023 trucks — a $2,000–$4,000 job because the transmission has to come out — and GM covers it free with an extended warranty only on the 2023 model year. A thrust-bearing failure surfaces from 2023 with no recall, only a GM test bulletin. Separately, recalls 24V797 and 26V083 cover a transmission control valve on 2020–2022 diesels that can lock the rear wheels — a software fix plus special coverage. This row is thinner than the V8s' because the diesel draws far fewer complaints, not because it is proven immortal.
The shudder — and, on 2020–2022, the one program with real teeth. The 8L90 eight-speed arrived around 2016 and brought a shudder you feel through the truck, plus surging and hard 1–2 shifts. It dominates the 2016–2019 complaint files and peaks in 2017, where owners quote $7,500 (dealer) and $4,670 (independent reman) and describe torque converters failing and sending debris into the filter. GM's fix is a flush with a revised fluid, which helps many trucks — a documented flush is a buying signal, and a light-throttle 25–50 mph drive is the test. It receded in 2018, then rode on into the new truck: 2023 still shipped the older eight-speed on some trims, with harsh shifts, delayed park-to-drive engagement and a class action. The bright spot is 2020–2022, where GM's Special Coverage for a worn transmission control valve (harsh shifting, reduced power, code P0747) runs 15 years or 150,000 miles from the in-service date regardless of ownership, with reimbursement for prior repairs — the single most valuable number on this page. Mechanics rate the ten-speed that replaced it markedly better.
The split is partial by design — we draw a row only where a GM campaign, a mechanic source, or a complaint cluster names that engine. Everything on this page also describes the GMC Sierra 1500: same platform, same engines, same programs, different badge and its own complaint counts — see the Sierra's page for the numbers and its GMC-only items (the MultiPro tailgate, the Denali's 6.2L skew, a grille-deflector recall). The VIN tells you which engine and transmission you actually have, and which recalls, special coverages and satisfaction programs apply — paste it and we'll tell you which row is yours.
