In owner complaints to the government, the areas named most are brakes, electrical, transmission & drivetrain.

Which Sierra HD diesel has the most engine complaints?

By VIN, the Duramax L5P: 16% of its complaints name the engine. The Duramax LLY has the lowest share, 7%. Shares of complaints, not failure rates.

Which Sierra HD years have the most complaints?

2001, 2003, 2004 drew the most complaints filed so far (170, 167, 167). Popular years draw more because more were sold, so these are counts, not a score.

Why doesn't the Sierra HD have a Lemon Index score?

No Lemon Index score: automakers report heavy-duty pickup sales together with the half-ton (one F-Series, Ram or Silverado number), so there is no honest per-truck denominator. These are counts and shares of owner complaints, not failure rates.

52 NHTSA recalls across model years 1999–2025.

Where is the Sierra HD in the GMC Sierra score?

Blended in: the GMC Sierra page scores the whole line, because sales are reported for the whole line. Its banner shows how much of each year is heavy-duty.

No Lemon Index score: automakers report heavy-duty pickup sales together with the half-ton (one F-Series, Ram or Silverado number), so there is no honest per-truck denominator.
