I just bought this 2020 Outlander LE new in March 2021. Since day one the Speedometer is consistently reading/displaying 5 km/hr faster than my actual speed. Anyone else with this problem or know how to fix it ?? The Mitsubishi dealer doesn't.

 

Not sure where in the world you are, but this explains the situation


Australian Speedo accuracy standards

Australian Design Rule 18 sets out the accuracy standards for vehicle speedos.

Until July 2006 this rule specified an accuracy of +/- 10 percent of the vehicle’s true speed when the vehicle was travelling above 40km/h.

That is, at a true vehicle speed of 100km/h the speedo could indicate between 90km/h and 110km/h.

An odometer accuracy of +/- 4 percent was also a requirement.

From July 1 2006 a new standard began its phase in and by 1 July 2007 all new vehicles had to comply. The new standard requires that:

• The speedo must not indicate a speed less than the vehicle’s true speed or a speed greater than the vehicle’s true speed by an amount more than 10 percent plus 4 km/h.
• Odometer accuracy is no longer defined.

What this means:

• For a vehicle travelling at a true speed of 100km/h, the speedo must read between 100km/h and 114km/h. The effect of this is that many drivers will find that at 100km/h they are driving up to 14km/h below the speed limit if they rely on the vehicle’s speedo.
• The speedo must always read 'safe', meaning the vehicle must not travel faster than the speed indicated by the speedo.

This change was made to align Australian vehicle rules with those already in place in Europe. It applies to all Australian motor vehicles except mopeds.Dealers will generally not attempt to correct speedo error unless it exceeds the legal requirements

 

I am in Canada. Do you know if the same accuracy standards apply in Canada ??

 

No i dont know. Just do what i did and google it
