All 1 Known Issue

On the 2024-2026 Chevrolet Trax, unlike the old 1.4L turbo, the 1.2L three-cylinder in the 2024+ Trax drives its camshafts with a rubber timing belt that runs submerged in engine oil. GM acknowledges the design's shedding behavior in preliminary information bulletin PIP5938, which tells technicians that a quantity of debris found in the engine oil of these engines is a normal wear-in characteristic of the wet belt and is not by itself cause for engine replacement. The concern for owners is what that debris does over time: shed belt material collects in the sump, can partially block the oil pickup screen and the small lubrication passages that feed the main and rod bearings, and is a leading suspected contributor to the low-mileage rod bearing failures now the subject of a class action. Extended oil-change intervals, low oil level, or cheap non-dexos oil accelerate belt degradation dramatically.

Common Symptoms

Black rubber particles or sludgy debris in the drain oil or oil filter
Oil level dropping between changes
Low oil pressure warning
Bearing knock developing after an extended oil change interval
Timing/cam correlation faults in later stages

How to Fix

There is no recall and no revised belt part number published. Practical protection is maintenance discipline: change the oil and filter every 5,000 miles with dexos1 Gen 3 0W-20 regardless of what the oil-life monitor says, never let the level fall below the dipstick's lower mark, and ask the shop to cut open or inspect the old filter for black rubber particles. If the filter or drain pan shows significant rubber debris, or the engine has ever run low on oil, have the oil pan dropped and the pickup screen inspected and cleaned before bearing damage occurs - that is far cheaper than the engine. Wet-belt replacement is a full front-of-engine job (pan and cover off) and runs well into four figures if a belt is ever found deteriorated.

Typical repair cost:$250 - $2,200
