The K24 powers Accord, CR-V, Element, TSX, and the 9th-gen Civic Si. Generally excellent - it is the engine you want in a high-mile Honda - but timing chain tensioner rattle (TSB 13-072 for CR-V) and 2008-2013 Accord excessive oil consumption (Soto v. Honda class action) are the two notable issues.
Excellent overall reliability. Famously high-mileage engine. Two known issues: timing chain tensioner rattle and 2008-2013 Accord oil consumption (class-action settled).
Honda 4-cylinder Accord with K24Z3 burns 1 quart per 1,000-2,000 miles past 70K miles - usually piston rings and PCV behavior. Covered by the Soto v. American Honda settlement on affected VINs.
View P0507 Diagnosis →TSB 13-072 (CR-V) addresses a rattle from the timing chain tensioner. Sounds like a worn alternator at cold start. Honda redesigned the tensioner.
View P0014 Diagnosis →Same VTC actuator pattern as the K20. Brief cold-start rattle. TSB-updated part fixes it.
View P0010 Diagnosis →The earliest K24 had a balance shaft belt next to the timing chain. Should be replaced at 100K, but most owners do not even know it exists.
Both are weeping seals at 150K+ miles. Cheap fixes.
View P0521 Diagnosis →Aftermarket cat eventually triggers P0420. OEM cat lasts 200K+, aftermarket often only 60-80K.

2008-2013 4-cyl Accord (oil consumption). 2003-2005 Accord K24 with neglected balance shaft belt.
2012-2015 9th-gen Civic Si K24Z7 (no balance shaft belt, no oil consumption). 2003-2008 TSX K24A2.
If you own a 2008-2013 Accord K24 and burn oil, check the class-action eligibility. Otherwise, plan on a $600-$1,200 tensioner job if it rattles after 100K, plus minor seals at 150K+. Mostly oil and plugs.

Yes - extremely reliable. Many examples cross 300,000 miles. The 2008-2013 Accord oil consumption issue is the only major reliability concern.
Soto v. American Honda (settled 2013) provided extended warranty and free piston ring replacements for affected 4-cylinder Accord owners. Most claim periods have closed.
250,000-350,000 miles with 5,000-mile oil intervals. The K24 is one of the longest-lived 4-cylinders in modern automotive history.
2003-2017 Accord, 2002-2017 CR-V, 2003-2011 Element, 2004-2008 TSX, 2012-2015 Civic Si, 2007-2009 RDX (turbocharged K23A1 variant).
No - the K24 uses a timing chain that does not require scheduled replacement. Early K24A versions have a separate balance shaft belt that should be replaced at 100K.
A short rattle from either the timing chain tensioner (TSB 13-072) or VTC actuator on cold start. Both have updated parts available from Honda.
