In my non-tech package GT, I've noticed the average speed and average mpg update very infrequently. Anybody else noticed this?

Mine updates every 15-30 seconds, I think that's just the way they work on the Mazda.

I have a Mazda 3 2011, mine is made in Japan and bought from a Mexican Dealer (Im from Mexico) and I have exactly the same issue.

I use to have a Mazda 6 2009 and I experience the same problem....the trip computer updates very infrequently.

My work is 18 km away from home (11 miles) and I have to use a highway to travel so I use plenty the cruise control.

Normally I drive in a constant of 110 km/hr (68 mph) and the trip computers since 4 weeks ago reports average speed of 39 km/h (24 mph) and barely moves no matter is my constant speed remains over 85km/h (52 mph) all the time.

No understand how the computers supposedly calculates every 2 seconds.

Mine is the same. I think the keyword is "average". This is not a realtime display, it needs time to calculate the "average" numbers.

In my old Cobalt, there was an option in the Information Center called MPG Inst. It was real time updating. The other option in it was MPG Avg that didn't update frequently at all. Hope this helps.

+1 Nothing to worry about

Just remember that its counting the 0 mph when youre at a stoplight and everything in between... i have a pretty even mix of highway and city and my average shows 27mph

Also remember the longer you drive without resetting it the longer it will take to calculate the average.

my averages are good, but my Trip A and B keep resetting... when i gas up ? :mellow 1:

Like everyone else is saying, the average is constantly being built up, so it gets harder and harder to change the average. My car was averaging 18.9mpg with like, 98% city driving, but after I took a few freeway trips, maybe 250 miles altogether while getting around 35-40mpg, my average mileage only went up to 19.0mpg.

I think all the 3s's have them. I know mine does.

"i" level 3's do not come with the trip computer, I think you have to get to the S level cars to get them from the factory, I added mine from a wrecked 3.

That's what I meant by 3s's.

Sorry bout that, somewhere I missed an "s" in there!:sad 1:

Yeah, what other people said: the average (as opposed to the next trip computer menu, instant) MPG/speed will be over a longer and longer period if you don't reset it. I've taken to habitually resetting my avg MPG and avg speed with each gas tank fill up, so my averages are built up somewhere between 0-400 miles.

Lol, it's all good.

I think I should start doing that. I'm getting tired of staring at the same low average MPG and speed. Darn city driving.
