I had my alternator replaced at a decent repair shop. 2004 MDX with 140k miles. I believe it‘s a reconditioned one they installed. Not sure if this is coincidental or not, but my MDX is now reporting 15.5 mpg instead of the normal 17.5 to 18 mpg. No other changes to the vehicle. It starts fine. I’ve owned this car for many yrs and never saw such low gas mileage. In the first few days after getting new alternator, the vehicle seemed a bit sluggish, like the brakes were engaged (not brakes, I checked) or engine was being restrained. Anyone out there have a similar experience? Maybe a bad alternator?
