My BT 50 2x4 ute registers 8-10 kms over the indicated speed.ie.,110 kms per hour is in fact 100kms per hour .There are at least 4 other vehicles in the area that do the same and the owners are particularily annoyed about it .The local dealer has tested these vehicles and acknowledged the error however Mazda will no rectify the problem as they state it is within ADR specs.
The error is over the whole speed range and is particularily annoying on the open road .Mazda advises you should just compensate for the error.
I rang the customer service line a week ago and was advised a "technician"would call me back.Still waiting!
Future buyers should be aware of this problem and I would be interested to see if anyone else has had it rectified.

Cheers

My work-ute is a Fraud - Ranger, aka BT-50,
It has the same problem.
I actually quite like it, I don't get booked for speeding...........

All my 4b's have had different tyre sizes put on, so I use a GPS for speed reading. Guess I'm just used to it now.

Pretty normal to be a bit over. 10% is slightly high perhaps.
Think of the fuel you'll save travelling at 90 instead of 100 :)

By the time the speed cameras have malfunctioned with there (pull a speed outa the hat) and you stick to the speedo speed you should be ok !

When it come to resale and fuel used it would show 110,000kms and only have done 100,000kms.
Service at 10,000kms only done 9,000kms.
Fuel using 10lts for 100kms is in fact 10lts for 90kms.
Have fun working it all out

Hi Corio,

The Navara has the same problem. It is about 9km out when doing 100 - speedo reads 100 actual is 91km/hr.

There have been many complaints to Nissan but get the same response as you do. It is a tad high I think, they (all manufacturers) have been building cars for a long time now and really should have it right by now!

Hey,
look on the brighter side of life, no tickets for speeding, now the down side is you know that when you are doing a dollar you are only doing 90 cents, this presents a problem cause if you are anything like me you will ramp it to a $1.20, thats when the man gets to notice you and hand out bits of paper you can't ignore.

There has been a lot of discussion on Sydney talk back radio over the last couple of weeks about speed cameras and the loss of three points for being less than 15 ks over the limit. Plenty of people have said all cars have their speedos set this way now because of the huge numbers being caught just a few ks over.

I don't know if it is true or not but I have not heard anybody call and disagree.

What's the point in etting your speedo rectified??

ADR's allow up to 10% error but no speedo is allowed to under read (ie; show 100 while actually doing 110).

To make things even worse, the difference between a new tyre and a just legal tyre is enough to throw your speedo out by up to 5%.

As many others have said elsewhere fitting non-standard tyres will also put your speedo out by varying amounts.

Just learn to live with it and count your savings by not getting flashed at your 110 (indicated).

Disco.

This seems to be std across most new vehicles these days. Our 07 subaru liberty is the same, as is vehicles like the X-trail, honda civic, new hilux. The only one I recently found OK was the ford xr6 (hire car). Not worth getting upset about really, less likely to get done speeding.

According to my GPS unit my 04 Rodeo ute was running 5km below the speedo and my Kia Sorrento about 7 km. I have been told they are allowed to be out by 10 km. Evidentally it is quiet common across the various makes

My BT 50 had the same problem.

I reasoned with the dealer and they agreed to fix it - under warranty.

They send the instrument pod to Melbourne, so the car is off the road for up to 5 days.

I know of at least one other BT 50s that has had its speedo recalibrated at the same dealer.

It's now only 4% out.....
