I just received paperwork from the feds concerning a suit that will acheive
Class Action status on Accord odometers. Of all cars, our '05 Accord is the
most accurate! I do, however, have a different car that has a similar 3-4%
error on the speedometer & odometer. So, now I'm wondering how common a
problem is this? If I switch tire sizes, it all goes out the window,
Anyone else question their odometer?
Sure. The odometer on my '88 Civic is about 2-3% off. For what it's worth,
slight errors can be adjusted for by switching to different tires. Try
experimenting with a tire size calculator such as
I've noticed when I pass through the school or police van radars my
2000 Ody shows about 2-3 mph below what my speedometer is showing. As
an aside, this is a replacement unit, because my first one blew (quit)
during the warranty period.

I've questioned the speedometer on my 2004 Accord as being a little
optimistic, reading 65mph when others are passing me in the presence
of Highway Patrol car! And, um, I forget what else triggered
suspicion, but I estimated at least 2-3mph discrepancy.
However, if anything, I suspected the odometer of being a tad
pessimistic, reading shorter than actual distances, maybe a couple of
percent in the other direction.
So the combination means I look at the speedometer, estimate my time
of arrival, and can't understand why I'm late.
On several long trips I have had a go at calibrating my speedometer. The
accuracy of my calculation is 100% dependent on the assumption that the
odometer is reading correctly. I set the cruise control to hold several
speeds, usually 60, 65, 70 and 80 mph and then record the miles traveled
over a 3 minute time period. The results were relatively consistent--the
speedometer reading was always higher than the calculated number and it was
a combination of a percentage of the speed plus a fixed value. The error was
4% of the speedometer reading plus 2. So when set to 80, calculated was 75;
70 vs 65, 65 vs 60, 60 vs 61 . Not too sure just how accurate this is but I
do know that when I was moving at the 70 mph (65 speed limit) I always
seemed to be the slowest one on the road.
Yes California does! Take a look at those little white rectangular
paddles along to side of the road. The Large numbers on them are
post-miles. Also at certain markers that end in ##.00 there will be a
large white mark in the middle of the sideline stripe. These may be 5
miles apart or less. This is so that the CHP can clock your speed from

My 2004 Accord is dead on. I've tested it several times and at various
speeds using a handheld GPS. I've also tested it against the traffic
signboards that tell you your speed as you approach it. Under all
curcumstances, the readings match up. I can't say the same for the three
Civics I owned previously.

In all of my past vehicles, they would be off by 1-2 at 30, and 3-4 at 60.
For decades, manufacturers have intentionally aimed for calibration
which was as much as 10% above reality. There are a number of
advantages to this - the owner thinks he is getting better gas
mileage, the car is lasting longer, maintenance intervals come sooner
and replacement of the vehicle will come earlier if the decision is
based on the odometer. That said, it seems like the odometers have
become more accurate over the last 10 - 15 years.
As you point out, tire size can throw off the odometer no matter how
well it was calibrated. Even tire wear and inflation will have minor
effects. Also, different brands/models of tires can vary slightly in
size, even if they have the same size designation. Add in a
reasonable production tolerance and a desire to error on the high side
and you can have perhaps a +4% error even though the manufacturer made
a good faith effort to deliver an accurate instrument.
That said, if the manufacturer can be shown to have intentionally
delivered a significantly miscalibrated odometer, it might be cause
for legal action to recover loses associated with excess vehicle
depreciation. To win this, I think they should have to show that the
manufacturer in question was significantly worse than comparable cars
in this regard since the value of a used vehicle is compared to others
on the market. The manufacturer could argue that the odometer
measures "odometer miles" which are comparable with other used
vehicles within the make if not between makes. He could even argue
that, if his make is worse than other in this regard, that the
over-optimistic odometer reading has given his brand a reputation for
quality that compensates for the excess mileage.
Do the papers provided by the court mention any specific level of
inaccuracy? If they can't show that the cars average at least +4%
with original tires, the case is bogus IMO.
I am a Honda owner and am furious. I received a copy of the
"settlement" in the mail yesterday. The only ones benefiting from the
suit are the attorneys that filed the case. The only benefit I can get
is "any out of pocket expenses occurring between "Mile 36,000" and
"Mile 37,800". If the mileage on the odometer is incorrect, then 1)
the MPG is not as good as was promoted and the advertising that
factored into my decision to buy a Honda was false; 2) both of the trip
meters also incorrectly state miles traveled; 3) Honda owners can not
sell their used Hondas for their actual value since the odometer
reading, which is a factor in the sales price, will overstate the
actual miles driven; 4) vehicle usage taxes owed will be erroneously
high, due to the overstated odometer.

This implies that the odometers are reading 5% high. Therefore you

Have you checked it?
The odometer does not affect your actual mileage of course. If you
mean that you are measuring your MPG and the number is 5% higher than
reality, then you need to factor that into your calculation. If you
are referring to the EPA estimate, then rest assured that the estimate
is in no way dependent on the accuracy of the odometer.
You need to factor this in, but I don't see how you have been harmed
This may or may not be a valid point. But consider that, to the
extent that used Odysseys compete with each other for buyers, they are
all at an equal disadvantage. To the extent that they compete with
other cars, we don't know how accurate those cars' odometers are. I
can tell you that +5% is pretty typical for odometer accuracy.
If you pay taxes on this basis, then you are overpaying. Where are
you that calculates taxes this way? I have never heard of this and it
seems ripe for cheating by periodically disconnecting the odometer.
I would have a hard time working up much anger about this.
They filed the suit so the lawyers could collect $9.8 million in legal
fees from Honda!
I'm sure that if Honda odometers consistently read LOW, the same four
lawyers would file in behalf of purchasers of used Hondas.
Texas' tort reform has chased these small fry lawyers into federal
