The 2.4L is a documented oil-burning grenade — only the 3.6L V6 version is worth touching.
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 2 of these are rated Critical.
40k–90k mi● Watch$200–$400MODERATE
TPMS sensor batteries dying prematurely — multiple sensors fail in quick succession
How to catch it: Replace all four with aftermarket Autel/Schrader sensors at the next tire change — cheaper than dealer OEM and reprogrammable.

50k–100k mi● Watch$250–$900MODERATE
Rear main seal and valve cover gasket seepage on the 2.4L
How to catch it: Look for oil sheen on the bellhousing during PPI — a slow VC leak is cheap, but RMS means engine or trans has to come out.

60k–120k mi● Critical$3,500–$6,500MODERATE
2.4L LEA excessive oil consumption — worn piston rings + failing PCV system causing 1qt per 1,000 miles or worse, often with no dash warning until bearings knock
How to catch it: Check oil every single fill-up, run a quart heavier than the dipstick 'full' mark, and swap to a thicker synthetic (5W-30 HM) — this is the #1 defect and NHTSA complaints confirm it.

60k–100k mi● Watch$80–$350MODERATE
Purge valve / evap solenoid failure causing rough idle, P0496 code, and fuel odor
How to catch it: Keep an ACDelco purge valve in the glove box — 15-minute swap on the intake manifold when the CEL trips.

70k–120k mi● Watch$300–$600HIGH
Wiper motor / windshield washer pump failure and cowl water intrusion — huge share of NHTSA complaints are wiper-related
How to catch it: Clear the cowl drains twice a year and test wipers in every mode before buying; a stuck wiper linkage is a $50 fix, a motor is $400.
Source: owner-reported (102 NHTSA complaints)
80k–130k mi● Critical$1,800–$2,800MODERATE
Timing chain stretch and tensioner wear on the 2.4L (and early 3.6L LFX)
How to catch it: Change oil every 5,000 miles max with dexos-approved synthetic — chain wear correlates directly with oil condition and level.

90k–140k mi● Plan$1,500–$2,800MODERATE
AWD transfer case / power transfer unit (PTU) failure — bearing whine then internal disintegration
How to catch it: Change PTU fluid every 30k (GM's 'lifetime' spec is fantasy) — buy the OEM synthetic and drain/fill yourself for under $50.
