Known problems with the 2023 Chevrolet Silverado 1500

4 of the 6 issues we track for the 2019–2025 generation are documented against the 2023 model year, and 1 carries a recall or service bulletin.

• 6.2L L87 crankshaft/rod-bearing failure, major recall

  majorNHTSA 25V-274 / GM N252494001

  GM recalled roughly 600,000 2021–2024 trucks and SUVs with the 6.2L L87 after 28,000+ field complaints of engine failure: sediment left on connecting rods and crank oil galleries plus out-of-spec crankshafts destroy rod bearings, seize engines, and cut propulsion. Dealers inspect; failed engines are replaced free, passing engines get 0W-40 oil, a new filter and cap. Listen for knocking and don't ignore a check-engine light.

  Typical cost: Free under recall (engine replacement or 0W-40 remedy)

• DFM lifter failure (5.3L and 6.2L)

  major

  Dynamic Fuel Management lifters collapse just like their AFM ancestors: sudden loud tick, flashing check-engine light, misfire on a deactivation cylinder, and possible cam damage. Heaviest complaint volume is 2019–2021; 2021–2023 6.2Ls also had a batch of blocks with oversized lifter bores that GM replaced whole engines for. Out of warranty, a lifter/cam job runs thousands, many buyers check for this before purchase.

  Typical cost: Free under 5-yr/60k powertrain warranty; $2,500–$5,500 (lifters/cam) or $8,000+ (engine) after

• Duramax oil-pump belt service everyone forgets

  moderate

  The 3.0L Duramax drives its oil pump with a wet belt at the back of the engine, and GM schedules replacement at 150,000 miles (LM2), a job that requires removing the transmission, typically $1,500–$3,000. The 2023+ LZ0 stretched the interval to 200,000 miles. Not a defect, but a real ownership cost that surprises high-mileage buyers.

  Typical cost: $1,500–$3,000 at 150k/200k miles

• Infotainment freezes and screen blackouts (2022+ refresh)

  minor

  The 2022 interior refresh brought the Google-built-in infotainment; early software froze, rebooted, or blanked the cluster/center screen intermittently. Most cases were fixed by over-the-air and dealer software updates. Annoying, occasionally persistent. Check for updates before replacing hardware.

  Typical cost: Free (software updates)
