What years of 5.3 are bad?
The worst years for the 5.3L engine are generally considered to be the 2007-2013 models due to issues with their Active Fuel Management (AFM) system, which can cause excessive oil consumption and lifter failure. Some 2019-2021 models also experienced issues, specifically with the newer Displacement Fuel Management (DFM) system. These problems can lead to costly repairs, and owners should frequently check their oil levels.
2007–2013 (Gen 4)
- Primary problem: Active Fuel Management (AFM) system, also known as cylinder deactivation.
- Specific issues:
- Oil consumption: The system can cause oil to be burned by the engine.
- Lifter failure: A ticking sound from the engine is a common symptom of the AFM lifters failing to work correctly, which can lead to severe engine damage.
- Carbon buildup: This can foul spark plugs and is often linked to AFM and the PCV valve, particularly in 2007-2011 models.
- Mitigation: Deactivating AFM with a tuner can often resolve these issues.
2019–2021 (Gen 5)
- Primary problem: Issues with the newer Displacement Fuel Management (DFM) system.
- Specific issues:
- DFM lifter failures .
- Engine bearing issues .
- High rate of issues .
Other years to consider
- 2010–2014: A class-action lawsuit was filed for models in these years, as they were significantly affected by the oil consumption issues.
- 2014–2016: These years for the Silverado are sometimes cited for other problems like A/C condenser leaks and transmission issues, although the AFM/DFM issues are engine-specific.
Is the 2002 5.3 a good engine?
They're excellent engines. Some higher mileage ones from that Era may have a small lifter tick, but it does nothing except just make noise (my 03 Suburban had it. Ran great otherwise).
