Anyone else notice a speedo error on their 2019s?

I have an SR 4x4 with the stock wheels (and tires) but my GPS keeps saying I'm about 3 to 4 miles fast on my speedometer. So when it says 75 my GPS/phone says 71... it's been accurate on all of my other cars so I'm pretty sure it isn't my phone that is wrong.

 

My 2013 was about 3 mph slower than the speedometer read out. I installed bigger tires recently and it corrected it for the most part. Went from 265/65 to 265/70. I don't know if you can have it recalibrated or not.

 

When you say stock wheels, I assume you also mean stock tires, yes?
This has been reported before, and isn't unusual across the automotive spectrum. What you're unlikely to find is a speedometer reading the other way around.

Same exact thing on my stock 2020. If speedometer says 75 I’m actually 72 or 73. My first time with a digital speedo, so maybe I’m just noticing because it’s so much clearer than an analog gauge. Good for MPG though i guess.

 

Same thing on my 2019 SR, which is completely stock. Speedo says I'm going 75, GPS says I'm going 72

 

Same on my SR. i plan on stepping up in tire diameter so it wont be as much of an issue

 

its normal, i believe honda or some other brand had a class action suit because it ran the warranty out so much faster. i like it because it will correct by bigger tire size when i will go up

 

Not sure which I prefer; it being a nanny thing to slow people down or a real product flaw.

 

i would have guessed it would be a way to report better MPG numbers. Thats a real sticking point for alot of consumers.... who want a truck and cant deal with the reality of owning one.

 

Not good for MPG. Basically it is telling you that you are getting better MPG than you actually are.

I think this whole speedo/actual speed difference thing is a conspiracy between the gubmint and the car manufacturers...they are trying to make us drive more slowly by having our speedo's calibrated such that we think we're going 80 when we're actually only going 75-78. We're all just pawns in their game...

 

But if I think im going 75 and actually going 72, I'm truly getting better mileage than if I was really doing 75.

 

I’d go with preferring the nanny myself.

 

But you are actually getting worse mileage than you THINK you're getting based on the MPG readout. You are traveling fewer miles per gallon than you think you are traveling because your speedo/tach are calibrated wrong. On top of that, as was mentioned previously, your warranty will expire sooner than it should because your tach is rolling up more miles than you are actually going.
hmmm...I wonder if we can get a class action lawsuit going against toyota for premature warranty expiration...

 

time to trade the truck in!!!! complain to corporate!!!! buy a ridgeline!!!!

 

Except for the Ridgeline suggestion I was thinking the same thing, reporting better mpg than I am really getting but... at least when I up to a 32 or 33" tire once the stock ones wear out I'll be at the right mph.

 

Enjoy life. It's not a police spec package

§393.82 Speedometer.

BMW has been doing this for years. All my M3’s were about 5 MPH slower than what the speedo said

 

Tarbal255, yes mines totally stock. I noticed it driving home the day I bought it while passing a portable radar speed sign near my house. I first thought the radar was wrong. But after passing a few others and plugging in my old Garmin I verified the truck speedo is off. I meant to bring it up on my 5k service but forgot.

 

Well, at least it might prevent me from getting speeding tickets.
