2011 Acura MDX

For the 2011 Acura MDX, engine complaints dominate the picture by a wide margin. The most commonly reported issue is excessive oil consumption, with owners describing oil levels dropping significantly between changes, in some cases the dipstick reading near empty within days of a fresh oil change. Many trace this to what they believe are piston-related problems, though the consistent symptom across reports is rapid oil loss. A number of owners also report check engine lights returning after attempted repairs, and some describe complete engine failure requiring full replacement. The powertrain draws a smaller cluster of complaints, mostly around hesitation and occasional transmission skip during acceleration. Electrical complaints are fewer but include a recurring note about reverse lights being too dim to provide useful visibility when backing up.
