Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.
40k–70k mi● Plan$250–$450MODERATE
eAssist / stop-start auxiliary 12V battery failure (the small AGM battery, not the main one)
How to catch it: Have any shop load-test BOTH batteries at every oil change; replacing the aux battery preemptively at ~5 years avoids the cascade of stop/start faults, ESC warnings, and no-start no-crank drama.

50k–90k mi● Watch$150–$600VERY HIGH
Shift-to-Park / electronic shifter module fault — car thinks it isn't in Park, won't let you remove key or lock doors
How to catch it: Check for the GM shifter reflash TSB has been performed (dealer records); if not, get it done now — it's usually free or cheap and preempts the more expensive shifter swap.
Source: documented (NHTSA recall)
60k–100k mi● Plan$700–$1,400MODERATE
A/C compressor clutch failure / condenser leak — common on 2.5L cars
How to catch it: Run the A/C for 10 minutes even in winter to keep seals lubed, and if it starts cycling loudly at idle in summer, replace the compressor before it grenades and contaminates the whole system.

70k–110k mi● Watch$400–$1,200MODERATE
Power steering assist reduced / EPS module fault (dash message, heavy wheel)
How to catch it: Keep the main battery healthy — most EPS 'Power Steering Reduced' warnings on these are voltage-related, not the rack itself; a fresh battery and clean grounds fix 70% of them.
Source: owner-reported (17 NHTSA complaints)
80k–120k mi● Watch$500–$1,000MODERATE
Passenger Presence Sensor (PPS) / occupant classification module — 'Service Airbag' light stays on
How to catch it: Don't ignore an intermittent airbag light — log the code with a scanner that reads SRS; if it's just a seat sensor connector, a $20 harness repair beats a $900 seat cushion.

90k–140k mi● Critical$1,200–$2,500HIGH
Timing chain stretch / cam actuator rattle on 2.5L LKW engine (cold-start rattle)
How to catch it: Change oil every 5,000 miles with dexos1 Gen2 5W-30 — NOT the 7,500-mile OLM interval GM allows; sludge and long intervals are what stretch these chains.
Source: owner-reported (20 NHTSA complaints)
100k–150k mi● Plan$300–$700MODERATE
Intake manifold / PCV diaphragm failure causing rough idle and lean codes
How to catch it: If you get a P0106 or P0171, don't chase sensors — pull a vacuum test on the valve cover; the integrated PCV diaphragm is the usual culprit and the whole cover is one part.
