According to my GPS, Toyota speedometers are less then accurate. I have proven that with 2 Toyota cars, and 2 GPS's. Both had original tires and the speedometers were 3 mph faster then the GPS readings. Not a big deal, but just a fact that seems odd to me. . Has anyone else tested theirs?
I've noticed the same thing with my 2011 Highlander Limited model with the 19-inch stock wheels/tires. Seems to read about ~3MPH faster than the GPS speed.
It’s a liability issue and not only Toyota has high reading speedos. There are variables that can fluctuate the gauge’s reading. If the speedometer reads low and you are fined for speeding or something worse, then you could potentially go back to the manufacture for damages.

Uh, no. The speedo in the 2005 HL is dead on accurate, so that blows your theory anyway. The reason for the inaccuracy is the conversion from the digital signal to the analog gauge. If Toyota put in a digital speedo, you'd see the accurate speed (which is why the odometers are accurate). For speeding purposes, CHP here in Calif automatically deduct 5 mph from the clocked speed to account for possible speedo errors.
Toyota actually allows up to 4 mph at 60 mph. The Tacoma is at 4 mph fast, the HL is at 3 mph (according to the radars that I've checked them against). What's interesting to note is that the Taco varies (it's 3 mph fast at 40 mph), whereas the HL is 3 mph fast at all speeds (it's 3 mph fast at 30 mph and at 65 mph). Sure, the analog gauge could be more accurate, but doing so with tighter tolerances probably costs more money. Cheaper to allow some error.

That is pretty much the universal error rate with Highlander owners as I've observed in these forums the past few years. My Highlander was 3 MPH too fast, and now that I've changed my tires from the OEM 245s to 255s, which changes the turn rate of the tire, the speedometer error is now down to 2 MPH too fast. IMO, that much error in a speedometer is ridiculous....

My '11 Limited speedometer reads 2% higher than 2 different GPS units at all speeds - 50mph on GPS = 52mph on speedometer, 75 on GPS = 78 on speedo. Better than the '11 Subaru I got rid of which was 4% off across the board.

Mine seems to be right no. I got a new garmin so I'll test it later.

My camry speedometer is 5mph more than my GPS. I tried my GPS on my Honda SUV and both have same speed. I think Toyota is somehow a bit off. No big deal thou unless theres a speedlaser pointing on you

this.
its a liability issue. they get them as close as they can, but not under.
