Head to head · Full-size pickups · 2020 · 2020 Ford F-150 vs 2020 GMC Sierra 1500
The 2020 F-150 is the year mechanics point to for this body style — complaints run under a third of the 2018 peak, and its engine habits are checkable in a single visit. The 2020 Sierra answers with paper: its costliest transmission failure is covered to 15 years/150,000 miles. What it asks instead is the lifter listen.

Control-valve failure under Special Coverage
The signature problems, with real repair money — every fact cited in the full reports.
Still the #1 complaint category, though at much lower volume than 2017–18. One recall matters here: a shift-cable clip defect can make the dash gear indication mismatch reality — rollaway risk if unremediated (20V-197). Confirm the dash indicator always matches the lever on your test drive.

The 2018–2020 5.0 can burn oil with no puddle, no visible smoke, and no warning light — owners report losing a quart every 1,000–3,000 miles without knowing, and 2020 is inside the affected window. Ford's fix is TSB 19-2365 (a revised dipstick plus a software update); it was warranty work, not a recall, so many trucks never received it. Ask specifically whether TSB 19-2365 was performed, ask about top-up habits, and check the dipstick yourself.

The 2015–2020 EcoBoost's signature problem: a metallic, diesel-like rattle on cold start that fades in about 30 seconds, caused by the variable-timing cam phasers and chain tensioners going marginal — usually downstream of stretched oil-change intervals. By 2020 the incidence is reduced versus 2017–18, but it's still reported. Caught at the first rattle it's a phaser/tensioner job; ignored, the timing chain stretches and the bill roughly doubles. The check costs nothing: arrive before the seller warms the truck up and listen to the first 30 seconds.

The good-news issue. On 2020–2022 trucks the 8-speed's transmission control valve can wear and lose pressure, causing harsh shifting, a service-engine-soon message, reduced performance, or a P0747 code. GM addressed it with a Special Coverage that runs 15 years or 150,000 miles from the original in-service date, regardless of ownership, installing a new control valve body free — and reimbursing owners who already paid. That means a common GM half-ton transmission complaint has a documented free remedy on this year. Confirm the truck is within the window and whether the valve was already replaced.

The uncovered risk. 2020 is all-DFM, the lifter system mechanics say fails more often and earlier than the older AFM. A collapsed lifter brings a tick, misfire, power loss, and often camshaft and pushrod damage — a $3,000–$10,000 repair with no blanket recall, only a class action and reactive, sometimes-denied warranty repairs. A DFM disabler (~$150) is cheap prevention; a cold-start tick is the tell to walk. This is the single most important thing to check on a 2020.

Alongside the lifter issue, the DFM V8s can burn oil — owners report a quart every 1,500–2,000 miles, and GM considers up to a quart per 2,000 within spec. The oil-cooler lines can also seep at the crimp. Check the oil level and look for leaks or a burning-oil smell; a truck that needs regular top-ups is telling you something about the engine's health.

How to actually decide, listing by listing.
Quiet-year rules
F-150: buy the engine, not the year.
The 5.0L oil-consumption interview and dipstick check, and the cold-start phaser listen on the 3.5L EcoBoost, decide any individual truck. Confirm the rollaway shift-cable recall (20V-197) shows closed while you're at it.
Sierra: the 15-year/150k control-valve coverage is the headline.
GM's special coverage on the 8-speed control valve turns this year's costliest transmission failure into a $0 event. Confirm the truck qualifies and keep the paperwork — that coverage is a reason to pick 2020 over 2019 on its own.
The Sierra's open question is still the lifter.
DFM lifter failure runs $3,000–$10,000 with no recall behind it. The ~$150 disabler module is the cheap hedge; an engine with documented lifter work is the better buy.
Both recall lists are free — they differ in kind.
Ford's 2020 items run to a starter-nut fire risk (20V-467) and breakable wiper arms; GM's include brake-caliper bolts (20V116) and a fuel-pump regulator (19V837). Every one is a free fix that must show closed on the VIN.
The matchup flips by year. Pick a different pair of cells and the verdict changes.
One truck sells you its service record; the other sells you its warranty booklet. Take whichever the seller can actually produce.
Paste either VIN and we’ll check its open recalls, campaign status, and build date against everything in these two reports — free.
