The Toyota 2AZ-FE 2.4L powered the Camry, RAV4, Highlander, Scion tC, and Solara from 2002-2009. It is mostly reliable, but two big issues - sludge on early years and a documented oil-consumption class-action campaign on later years - demand attention before you buy.
2002-2003 had sludge problems with an extended warranty offer. 2007-2009 had an oil-consumption class action with piston replacements. Verify VIN-specific campaign status before purchase.
A class action settlement covered piston ring redesigns on affected 2AZ-FE engines. Toyota replaced pistons under the campaign - check the VIN before purchase.
Run free diagnosis →Early 2AZ-FE engines were prone to oil sludge buildup if oil changes were skipped. Toyota offered an extended warranty - always verify oil-change history.

2002-2003 (sludge risk) and 2007-2009 Camry/RAV4 without verified piston-replacement campaign records.
2004-2006 2AZ-FE engines - after the sludge fix, before the oil-consumption issue. Verify oil-change history regardless.
Verify the VIN was covered by the oil-consumption campaign. Otherwise plan $400-$700 for a water pump at 120K and budget for potential head-bolt issues if a major repair is needed. Total lifetime cost ranges $2,000-$8,000 depending on campaign coverage.
Codes most often associated with the 2AZ-FE 2.4L.
Yes - a class action covered excessive oil consumption on 2007-2009 Camry and RAV4 models. Toyota replaced pistons under the campaign.
Yes, on 2002-2003 model years. Toyota offered an extended warranty for affected owners. Later years had the issue resolved.
Not necessarily - just verify oil-change history and check VIN against the oil-consumption campaign. 2004-2006 are the safest 2AZ years.
With proper oil changes and addressed campaign work, 200,000+ miles is common.
The head bolts can strip the aluminum block threads, especially during head gasket service. Time-serts or heli-coils are a known repair.
