The Toyota A25A-FKS 2.5L Dynamic Force engine is the modern replacement for the 2AR-FE, found in 2018+ Camry, 2019+ RAV4, Lexus ES 250, and Highlander. The early years had complaints, but newer builds are showing promising long-term reliability.
2018-2020 had early-launch oil consumption complaints; Toyota addressed via software and ring redesigns. 2021+ are showing strong long-term promise.
Early A25A engines reported a quart per 1,000-2,000 miles. Toyota addressed it via software updates and revised piston rings mid-cycle.
Run free diagnosis →The auto stop-start can fail to restart smoothly or trigger battery warning codes. Often resolved with a battery replacement or software update.
Run free diagnosis →Like all GDI engines, the A25A accumulates carbon on the intake valves over time. Symptoms appear around 60K-90K miles.
View P0300 Diagnosis →Multiple TSBs cover small calibration tweaks for shift behavior, throttle response, and stop-start logic. Most are free dealer reflashes.
Run free diagnosis →Some A25A engines develop a brief cold-start tick from the high-pressure fuel pump. Generally benign and tracked under TSB.
Run free diagnosis →The 12V battery sees heavy duty cycling from the auto stop-start. Plan on a 3-4 year battery replacement interval, shorter than older Camrys.

2018-2019 Camry/RAV4 with no oil-consumption test on file - verify the dealer documented consumption per Toyota guidelines.
2021+ Camry and RAV4 A25A - oil-consumption complaints have largely settled and the calibration is mature.
Plan around $400-$700/year in routine maintenance plus around $400-$700 for a walnut-blast carbon clean every 60K-90K miles. Stop-start battery replacements run $200-$350 every 3-4 years.
Codes most often associated with the A25A 2.5L.
Yes - after some early-launch oil consumption complaints, the A25A has matured and is showing strong reliability on 2021+ models.
Some 2018-2020 examples did. Toyota addressed it via software updates and piston ring redesigns. Track consumption and have the dealer document it if it exceeds spec.
Most A25A stop-start failures are 12V battery related. Heavy-duty AGM batteries last 3-4 years under stop-start cycling.
Yes - the A25A is interference. It uses a timing chain (no belt).
The A25A is a clean-sheet design with a 14:1 compression ratio, dual injection (port + direct), and Atkinson-cycle operation. It is more efficient and produces more power than the 2AR-FE it replaced.
