I PURCHAESD A NEW 07 TOYOTA TACOMA VEHICLE IS TOTALLY STOCK INCLUDING TIRES AND WHEELS,HOWEVER THE SPEEDOMETER AND ODOMETER IS OFF BY 9 % [IT READS FAST] AT FREEWAY SPEEDS 65 MPH WHICH MEANS FOR EVERY 91 MILES I DRIVE ODOMETER REGISTERS 100 MILES. ANY OTHER TOYOTA OWNERS NOTICE THIS PROBLEM?
An error of 9% is too much, bring it back to the dealer and have them correct it. It’s not unusual to have an error of a couple of percent.
IVE BEEN TO DEALERSHIP FOR REPAIRS THEY SAY SPEEDO IS[ WORKING AS DESIGNED] THEY DONT SAY ITS ACCURATE.I AGREE 9% IS NOT EVEN CLOSE
I believe there was something on the news a few months ago about a lawyer that filed suit against toyota for the speedometer being off by so much.
I would keep complaining to the dealer and toyota until they fix it.
I HAVE NOT HEARD OF A LAWSUIT BUT IM THINKING MY VEHICLE IS NOT THE ONLY ONE LIKE THIS .MOST PEOPLE DONT NOTICE . I CHECKED MINE WITH G. P. S. AND THEN TO SPEEDOMETER REPAIR SHOP WHERE THEY CERTIFY SPEEDOMETERS.THE GUY AT SPEEDO SHOP TOLD ME A LOT OF NEW VEHICLES ARE LIKE THIS HE MENTIONED HONDA AS ONE OF THEM. I THINK THEY ARE DOING IT SO YOUR WARRANTY EXPIRES BEFORE IT SHOULD 36000 MILES MINUS 9% =32760 MILES
Exactly. That’s what the lawsuit was about.
It’s quite possible for a speedometer to be wrong by several percent. However, that’s not acceptable on a new vehicle which is under warranty. Toyota should fix it for free.
The odometer is much more likely to be correct. I assume you have compared the odometer to highway mileposts on a reasonably long drive. If you go 91 miles according to the mileposts and the odometer shows 100 miles, there is a big problem. I don’t know if the odometer is driven mechanically or by computer software. For purely mechanical odometers, the only sources of error are the differential gear ratio and tire size. If a computer program is involved, it could be a programming error such as the wrong conversion factor between input pulses and miles.
THE WAY I UNDERSTAND IT IS WHEEL SPEED SENSORS THE SAME SENSORS USED FOR A.B.S BRAKE SYSTEM SEND INFO TO COMPUTER WHICH IS THEN SENT TO SPEEDO AND ODOMETER.

One lawsuit on odometer error and warranty coverage.
It is normal for the speedometer to be optimistic by about 5%. However the odometer should be very close. There will be some change as the tyres wear, but it should be a whole lot closer than you indicate. That should be corrected under the warranty.
I wouldn’t call that “normal” but many do read high (until you have them properly calibrated). I might live with 2%, not 5% or greater.
THANKYOU JOSEPH MEEHAN FOR THAT LINK THAT IS A VERY INTERESTING STORY
I had a brand new 84 Mazda which was off by 5.5%. I pushed the issue all the way up to the US Mazda technical support offices. Their official statement was that any tolerance within +/- 7% was “normal and acceptable”. I wasn’t happy, but it was clear they weren’t going to do anything about it.
