Is it normal for the Lambdas to have a significant delay when using the resume feature of the cruise control? It takes a good 3-4 seconds from hitting the button to feeling the car accelerate to the previous speed. Neither my Mazda3 nor my Honda Odyssey had such a big delay.

Alot of times- I dont use this resume feature-- beause it downshifts and rpms go way up to get up back to speed...
I prefer to do it gradually (to save gas)...
Though I have not timed to see if it mimics yours.

I don't use the resume feature either; I have found in the past that my Acadia downshifts 1 to 2 gears until it gets back to the previous set speed. As far as the time; I would guess it would be in the 3-4 second range

I'm surprised that folks aren't using resume. 3-4 seconds to feels like an eternity, especially if you've jumped out in traffic to pass a slow driver.

And to clarify - it's not 3-4 seconds to get back to speed, it's 3-4 seconds before it starts accelerating at all. None of my other cars had such a delay.

I guess I'll take it in while I'm still under the 3/36, I just figured I'd avoid the trip if they all did it.

I've actually heard that for better mileage it's better to floor it and get up to speed as quickly as you can. The theory being you want to spend as much time at the most efficient speed as possible. I have a reasonably heavy foot and get 17/23.5 with my outlook.

I have a relatively heavy foot as well (set cruise at 8 over the limit, 73 MPH most places around here) and have only managed ~20 MPG on the one road trip I've taken without my trailer.

I dont know about this one...
flooring it--- increasing RPMs and dumping fuel to get the brick up to the speed you want----- is going to use alot of gas.
vs- taking it easy- in low RPMs and gradually increasing speed will use less fuel....... at least thats how I see it.

I would also agree that this delay is likely to be normal operation. However, if you feel that this is the result of some kind of issue, I would recommend contacting your local dealership. Please feel free to keep us updated regarding the concern.
