What owners describe

Engine

Many owners report their MDX engines burn through oil far faster than expected, sometimes needing a quart added every 1,000 miles or less. Some also describe knocking noises, warning lights, or reduced power, and say dealers offered mixed responses ranging from warranty repairs to calling the consumption normal.

Warning signs:
Owners report an oil-level or check-engine light, knocking or rattling noises, burning odors, vibration, and gradual loss of power before oil needed topping off.
What shops did:
Some dealers ran oil consumption tests, called the consumption normal, or included owners in a warranty extension for repairs; others could not resolve the issue or said coverage had expired.
Mileage:
most between 60,000 and 115,000 miles, among 15 complaints that give it

“The vehicle started consuming oil around 80,000 miles. At 90,000 miles the engine was consuming 1 quart every 1,000 miles”

“The oil indicator light has come on repeatedly. Also, the 'check emissions system' has also displayed after driving on the freeway.”
