GMC Sierra 1500 Filters and Fluids: 4 Symptoms Worth Taking Seriously (2014-2018)

Most filters and fluids problems announce themselves well before they strand anybody. On a 2014-2018 Sierra 1500, these are the ones worth acting on.

1. A diesel that derates or throws a fuel pressure code on a neglected filter

By the time this is obvious you are generally replacing more than one part. Start by looking at cabin air filters.

2. A slight hesitation on hard acceleration with a dirty air filter

By the time this is obvious you are generally replacing more than one part. Start by looking at cabin air filters.

3. Reduced airflow from the vents

It rarely gets better on its own, and it usually gets louder before it gets expensive. Start by looking at air filters.

4. An oil life monitor that reaches zero faster than it used to

By the time this is obvious you are generally replacing more than one part. Start by looking at air filters.

What to Do Next

Follow the oil life monitor rather than a fixed mileage. Engine air filter every 30,000 to 45,000 miles. Transmission service intervals vary widely by transmission and by whether you tow.

Engine size and emissions equipment change the filter, and diesel filter kits in particular are not interchangeable across model years.
