When your apple macbook air 13" (m2) is most likely to develop issues, based on community repair data and manufacturer patterns.

The most common failure types, sorted by when they typically appear.
The MacBook Air M2 uses a revised Magic Keyboard with scissor-switch mechanism — a major improvement over the butterfly keyboard era. However, individual keys can still fail from debris ingress, liquid spills, or mechanical wear. The critical issue: the keyboard is riveted to the top case. Apple service replaces the entire top case assembly (keyboard, trackpad, speakers, battery) for a single failed key, which costs $400+ even out of warranty. Third-party keyboard repair is possible but voids warranty and requires specialized tools.
The MacBook Air M2 has no cooling fan — the aluminum chassis is the only heat sink. Under sustained workloads (video export, compilation, ML inference), the M2 chip reaches thermal limits faster than in the MacBook Pro, causing CPU and GPU frequency to drop significantly. This is by design, not a failure — but performance can degrade 30-50% during extended heavy tasks. Thermal paste between the chip and heat spreader also degrades over 3-4 years, worsening this effect over time.
The MacBook Air 13" M2 uses a 52.6 Wh battery rated for 1000 cycles to 80% capacity. The fanless design means the M2 chip runs warmer during sustained tasks, which accelerates battery chemical aging compared to cooled alternatives. Battery health below 80% triggers macOS service recommendation. The battery uses pull-tab adhesive strips and is accessible via bottom case removal, but Apple often replaces the entire top case (keyboard, trackpad, speakers, battery) as an integrated assembly.
